Mid-term results of zone 0 thoracic endovascular aneurysm repair after ascending aorta wrapping and supra-aortic debranching in high-risk patients

2017

Objectives Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. Methods During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included. All patients were considered at high risk for conventional surgery. Measured outcomes included perioperative deaths and morbidity, maximal aortic trans…

Endovascular treatment of large and wide aortic neck: case report and literature review

2017

Large (24–34 mm) and wide (≥35 mm) aortic necks are a contraindication to endovascular aneurysm repair (EVAR). A 63-year-old man, unfit for conventional surgery, presented a 79 mm abdominal aortic aneurysm with 36.5 mm aortic neck and a 62 mm right common iliac artery aneurysm. He was treated endovascularly with standard commercially available stent-graft using the so-called ‘funnel technique’; by placing a thoracic stent-graft inside a bifurcated device to achieve proximal sealing. The completion angiography and the 6 months follow-up with computed tomography showed no stent-graft migration, limb occlusion or endoleak. The literature review reported 179 cases of large aortic neck managed w…

Carotid Artery Disease in the Era of Biomarkers: A Pilot Study

2023

The intima-media thickness (IMT) and its irregularities or ulcerations in the common carotid artery (CCA) are useful tools as sentinel biomarkers for the integrity of the cardiovascular system. Total homocysteine and lipoprotein levels are the most commonly used elements in cardiovascular risk stratification. Duplex ultrasound (DUS), associated with serum biomarkers, can be used simply to assess the degree of atherosclerotic disease and cardiovascular risk. This study highlights the role of different kinds of biomarkers, showing their usefulness and potentiality in multi-district atherosclerotic patients, especially for early diagnosis and therapy effectiveness monitoring. A retrospective a…

CEA vs CAS

2009

Objectives: Last years registered an increment in the number of endovascular procedures. Traditional carotid endoarterectomy (CEA) is the most performed surgical treatment for carotid stenosis. In symptomatic patients CEA reduces significantly absolute relative risk of stroke and death. In asymptomatic patients AHA guidelines recommend CEA for stenosis 60–99%, if the risk of perioperative stroke or death is <3%. According to 2007 Clinical Expert Consensus Document Carotid Artery Stenting (CAS) should be used in patients at high-risk for CEA or into controlled trials and Cochrane Database of Systematic Reviews does not support a widespread change in clinical practice away from recommending C…

A New Off-Pump Hybrid Open and Endovascular Repair to Treat Ductus Botalli and Ascendens Aneurysms

2012

To report a combined ascending aorta and aortic arch hybrid repair, we performed off-pump with no aortic graft replacement. A 65-year-old man, developing progressive recurrent laryngeal nerve paralysis, underwent a computed tomography (CT) angiography detecting nonpatent residual ductus Botalli aneurysm and ascending aorta aneurysm. Due to severe multimorbidities, a less-invasive alternative was elaborated. In a first step, appropriate proximal landing zone for aortic stent grafting was achieved by ascending aorta diameter reduction, with epiaortic wrapping, and debranching the supra-aortic trunks. In the second step, endovascular stent grafts were deployed from proximal ascending aorta to…

Stent-assisted detachable coil embolization of wide-necked renal artery aneurysms

2017

Renal artery aneurysms (RAAs) are rare with an estimated incidence of 0.1% in the general population, and they represent approximately 25% of all visceral aneurysms. The gold standard of treatment is open surgery, but it is associated with a high risk of nephrectomy, mortality, and morbidity. Less invasive endovascular therapies are becoming increasingly common for the treatment of RAAs. Here, we aimed to report three cases of wide-necked complex renal artery aneurysms treated endovascularly using stent-assisted coil embolization with self-expandable stent nitinol Solitaire AB and Concerto Axium coils. In addition, we describe the use of the waffle-cone technique in a case of wide-necked sa…

European guidelines on chronic mesenteric ischaemia - joint United European Gastroenterology, European Association for Gastroenterology, Endoscopy an…

2020

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. The underappreciation of this disease results in diagnostic delays, underdiagnosis and undertreating of patients with chronic mesenteric ischaemia, potentially resulting in fatal acute mesenteric ischaemia. This guideline provides a comprehensive overvi…

Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry

2017

Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …

Insufficienza Celiaco Mesenterica

2022

L’insufficienza celiaco-mesenterica (ICM) è una sindrome clinica in cui il sintomo cardine è rappresentato dal dolore addominale che insorge nella fase post-prandiale, e che è provocata dall’inadeguata vascolarizzazione di uno o più settori dell’apparato digerente. Essa insorge per la presenza di lesioni ostruttive a carico delle tre principali arterie splancniche: il tripode celiaco (TC), l’arteria mesenterica superiore (AMS) e quella inferiore (AMI). Esistono due forme di ICM, una acuta e una cronica, che differiscono dal punto di vista fisiopatologico, oltre che per eziologia e clinica, sottolineando peraltro la possibile evoluzione improvvisa da cronica in acuta, fino all’evoluzione in …

Complete renovisceral debranching and EVAR for thoracoabdominal aneurysm

2011

Open graft repair of thoracoabdominal aortic aneurysms (TAAA) is an incredibly complex and challenging procedure with acceptable results achieved only by a few centers worldwide. Contemporary outcome analysis of TAAA repair performed in the United States showed greater operative mortality and morbidity rates than commonly reported. Moreover, a recent European long-term follow-up study showed that survival remains suboptimal, especially in the early years after TAAA repair. Complete renovisceral debranching combined with EVAR offers many advantages in regard to open surgical repair with comparable or better results, especially in the high-risk patient. Although this hybrid procedure will not…

SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study

2021

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 da…

Carotid artery stenting with contralateral carotid occlusion in a rare aortic arch configuration

2010

We present the case of a 47-year-old man admitted to our department with an episode of aphasia. Duplex scan showed an occluded right internal carotid artery and severe left internal carotid artery stenosis. Contrast-enhanced computer tomography demonstrated a common trunk for both common carotid arteries anterior to the trachea and aberrant right subclavian artery posterior to the esophagus. The patient was considered to be a high risk for carotid endarterectomy and, consequently, we performed stenting of the left carotid artery. To our knowledge, this is the first case reporting the combination of these two aortic arch anomalies and the concomitant endovascular treatment of atherosclerotic…

EVAR IN OUT CLINIC PATIENTS: IS IT FEASIBLE AND SAFE?

2013

Introduction Only little is known about endovascular aneurysm repair (EVAR) performed as an outpatient procedure. We report here a two-center (Middelares Hospital, Antwerp (Deurne), Belgium and University Hospital Zurich, Switzerland) experience in 104 EVAR patients of which a group of 52 patients have been treated on an outpatient (out-EVAR) basis and compared to a matched group of 52 patients that have been treated as inpatients (in-EVAR). Methods Selection criterions for out-EVAR were: informed consent, travel time to the hospital if readmission was required of <30-60 minutes, and technically uncomplicated EVAR. Most out-EVAR has been treated percutaneous. In-EVAR patients consisted in a…

Chronic Mesenteric Ischemia: Critical review and guidelines for management

2011

Background CMI is caused by chronic occlusive disease of mesenteric arteries. In such an uncommon disease, clear recommendations are strongly needed. Unfortunately, treatment options for symptomatic CMI are still controversial and no guidelines exist. Methods A systematic literature review of the last 25-years was conducted through MEDLINE, Embase, and Cochrane Review/Trials register to identify studies reporting on CMI treatment with more than 10 patients. Primary outcomes were perioperative mortality and morbidity rates. Secondary outcomes were survival rates, primary and secondary patency rates, vessels treated, CMI recurrence, follow-up (FU), technical success (TS), and in-hospital leng…

Simultaneous appearance of leukemoid reaction and phlegmasia cerulea dolens

2012

A leukemoid reaction is an extreme form of reactive leukocytosis defined as granulocytic leukocytosis above 50 × 109/L produced by normal bone marrow, mostly in response to systemic infection or cancer. The mechanism as to how the haematopoetic system is altered to elevate production of myeloid cells is not known. A 69-year-old man presented with phlegmasia cerulea dolens caused by massive iliofemoral thrombosis. His workout at admission revealed absolute white blood cell count of 73.4 × 109/L, with neutrophil granulocyte of 68.5 × 109/L. The new increase in white blood cell count happened at day 5 after admission, when the haematoma of the anteromedial thigh was evacuated in general anaes…

Hypotensive Hemostasis in Patients Presenting with Ruptured Aortic Aneurysm

2017

Hypotensive hemostasis in aortic rupture has been showed to be feasible and advantageous, especially in trauma patients. To date, there are no randomized studies on hypotensive hemostasis in patients with ruptured abdominal aortic aneurysm (rAAA), but observational studies indicate similar advantages when hypotensive hemostasis is used for endovascular aneurysm repair (EVAR) as in trauma patients. Actually, in EVAR for rAAA, a target systolic blood pressure of 90 mmHg or even lower is considered safe in conscious patients. Fluids should be administrated judiciously with the sole aim of maintaining adequate cardiac output and tissue oxygenation, whereas vasoactive pressors or dilatators may …

Results of chimney endovascular aneurysm repair as used in the PERICLES Registry to treat patients with suprarenal aortic pathologies

2020

Background: The prevailing evidence calls for using chimney/snorkel endovascular repair (ch-EVAR) with one or two chimney grafts. No studies up to now focus on its applicability and results for the treatment of suprarenal aortic pathologies (SRAP). Hence, we evaluated the clinical and radiologic results of ch-EVAR treatment for SRAP placing three or more chimney grafts within the PERICLES Registry. Methods: Data from 517 patients suffering complex aortic pathologies treated by ch-EVAR between 2008 and 2014 at 13 European and U.S. centers were retrospectively reviewed and analyzed. Results: Sixty-seven ch-EVAR-treated patients (12.9% of the entire PERICLES cohort) presented SRAP (83.5% elect…

Type 1A endoleak detachable coil embolization after endovascular aneurysm sealing: Case report

2021

Introduction Endovascular aneurysm sealing (EVAS) with the Nellix system was introduced to reduce endovascular aneurysm repair (EVAR) perioperative complications, especially endoleaks. Herein we report a case of successful type 1A endoleak managed with detachable coils embolization after EVAS. Presentation of case A 77-year-old male was referred for abdominal pain. The angio-CT scan confirmed the previous EVAS procedure and showed a type Is2 endoleak below the right renal artery resulting in a 2.5 cm aortic blister with contrast medium filling the space between the aortic wall and the endobags. The patient was considered unfit for conventional open surgery and an endovascular approach with …

Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEM) of a Customized Stent-Graft for Endovascular (EVAR) Treatment of Abdominal Aorti…

2023

Background: The treatment of abdominal aortic aneurysm (AAA) is today commonly treated by inserting a stent-graft by the endovascular route, without resorting to open surgery. However, some clinical cases do not allow this less invasive approach, meaning that the stent-graft cannot be inserted and open surgery is used. Methods: In the study, we propose a fluid–structure interaction (FSI) analysis of an aneurysmatic aorta that could not be treated with Endovascular Aneurysm Repair (EVAR). The vessel is reconstructed through segmentation from CT scans and subsequently modeled on CAD software to create the surface and thickness of the vessel itself. Subsequently, we proceeded to carry out Comp…

Surgical repair of popliteal artery aneurysms remains a safe treatment option in the endovascular era: a 10-year single-center study

2012

Introduction: Endovascular popliteal artery aneurysm repair has emerged recently as a feasible alternative to standard surgical repair. However the evidence from the literature is still limited, with only case reports, case series and one small randomized trial. Currently these data suggest the use of stent-grafts in patients at very high surgical risk. The purpose of this study is to present our surgical experience in popliteal artery aneurysm repair in an era of endovascular philosophy. Materials and Methods: Data from 36 consecutive patients who were admitted to our hospital from January 2000 to April 2010, were analyzed retrospectively. Twenty-six patients underwent surgical treatment t…

Endovascular treatment of spontaneous isolated abdominal aortic dissection

2016

Isolated abdominal aortic dissection is a rare clinical disease representing only 1.3% of all dissections. There are a few case series reported in the literature. The causes of this pathology can be spontaneous, iatrogenic, or traumatic. Most patients are asymptomatic and symptoms are usually abdominal or back pain, while claudication and lower limb ischemia are rare. Surgical and endovascular treatment are two valid options with acceptable results. We herein describe nine cases of symptomatic spontaneous isolated abdominal aortic dissection, out of which four successfully were treated with an endovascular approach between July 2003 and July 2013. All patients were men, smokers, symptomati…

Treatment of isolated ascending aortic aneurysm by off-pump epiaortic wrapping is safe and durable.

2016

OBJECTIVES: Isolated ascending aortic aneurysm (iAA) is usually treated by open graft repair requiring sternotomy, cardiopulmonary bypass (CPB) and cardioplegia. This approach carries significant mortality in older patients or those presenting with comorbidities. We report an original series of patients presenting with iAA and treated with epiaortic wrapping by using a synthetic mesh. This less invasive aortic repair technique allows reducing the aortic diameter to a predefined value and is performed without CPB. METHODS: Data from patients presenting with an iAA and treated with the wrapping technique (WT) by polypropylene/polyester mesh from November 2006 to July 2015 were collected. The …

Periscopes, chimneys, sandwich and VORTEC to facilitate abdominal and thoracoabdominal aortic aneurysm repair

2012

The VORTEC (VIABAHN open revascularization technique) and the chimney graft technique are tools with which to maintain or restore blood flow to the aortic branches and can be used intentionally or as a bailout procedure in open surgery or endovascular procedures. VORTEC is a stent graft-based vascular connection technique that achieves end-to-end anastomosis configuration; it is especially useful when the traditional suture technique proves (can be) cumbersome. It is also a speedy tool with virtually no blood flow interruption and no anastomotic bleeding, and patency rates compare favorably with sutured anastomosis. The chimney/periscope, as well as the sandwich graft technique (CHIMPES), i…

Akute Gefäßerkrankungen in der Gastroenterologie. Der Gastroenterologe - Acute gastroenterologic vascular diseases

2012

Acute gastroenterologic vascular emergencies are common situations in emergency departments and the clinical consequences range from trivial to life-threatening. Only the early recognition of these symptom patterns and prompt use of the appropriate diagnostic tools lead to a correct diagnosis with subsequent potentially life-saving treatment. To decrease the high mortality rate of acute mesenteric ischemia (50%), aorto-enteric fistula (30–40%), visceral artery aneurysms (10– 100%) and Budd-Chiari syndrome new strategies with an endovascular approach are gaining importance and are partially replacing established diagnostic and therapeutic algorithms. This article provides a review of the dia…

A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…

2012

Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were p…

Use of covered chimney stents for pararenal aortic pathologies is safe and feasible with excellent patency and low incidence of endoleaks.

2012

Background To present the clinical experience of consecutive series with use of balloon-expandable and self-expanding chimney endografts (balloon-expandable covered stent group [BECS] vs self-expanding covered stent group [SECS]) in the endovascular treatment of challenging aortic pathologies requiring renal and/or visceral revascularization. Methods Between January 2009 and May 2011, data for 37 high-risk patients from one center and 35 patients from another institution, with pararenal aortic pathologies treated by the chimney endovascular technique, were prospectively collected. The chimney-graft technique is based on the deployment of a covered or bare-metal stent parallel to the aortic …

Periscope endograft technique to revascularize the left subclavian artery during thoracic endovascular aortic repair.

2013

Purpose: To present early and midterm results of the periscope endograft (PG) technique to maintain left subclavian artery (LSA) blood flow in thoracic endovascular aortic repairs (TEVAR) involving zone 3. Methods: From April 2010 to January 2013, 14 consecutive high-risk patients (11 men; mean age 7068 years, range 56–87) underwent TEVAR with the PG technique for 10 thoracic aortic aneurysms (TAA), 2 traumatic aortic ruptures, and 2 aortic dissections without a suitable landing zone (.2 cm distal to the LSA). Five procedures were performed emergently for rupture (3 TAAs and the 2 trauma cases). Two patients had a periscope deployed in an aberrant right subclavian artery. The periscope endo…

Staged acute mesenteric and peripheral ischemia treatment in COVID-19 patient: Case report

Introduction COVID-19 is an infectious disease that has been associated not only with respiratory complications. The COVID-19 disease includes, also damage to other organ systems as well as coagulopathy. The present report describes a case of COVID-19 presenting with acute mesenteric ischemia (AMI) and subsequent acute limb ischemia (ALI). Presentation of case An 84-years old hospitalized female patient presenting diabetes and recent COVID-19 reported acute onset of abdominal pain and typical findings of AMI. The CT-angiography confirmed the AMI secondary to a superior mesenteric artery (SMA) occlusion. The patient was managed through an endovascular approach using a SMA mechanical thrombec…

Branch ligatures and blood aspiration for post-traumatic superficial temporal artery pseudoaneurysm: surgical technique

2014

The aim of this study is to report a new minimally invasive technique of superficial temporal artery (STA) pseudoaneurysm treatment. Several surgical options have been employed to treat STA pseudoaneurysms. To address this rare condition, the employed techniques are ligation and excision of the aneurysm, endovascular coil embolization or percutaneous ultrasound-guided thrombin injection. Between techniques no significant differences are reported in terms of outcomes. The decision to adopt a technique depends on STA pseudoaneurysm morphology and surgeon preference. In the present report, STA pseudoaneurysm afferent and efferent branches were identified by ultrasound in a 92-year-old female. …

Late Complication after Superficial Femoral Artery (SFA) Aneurysm: Stent-graft Expulsion Outside the Skin.

2014

A 78-year-old man presented with a 7-cm aneurysm in the left superficial femoral artery, which was considered unfit and anatomically unsuitable for conven- tional open surgery for multiple comorbidities. The patient was treated with stent-graft [Viabhan stent-graft (WL Gore and Associates, Flagstaff, AZ)]. Two years from stent-graft implantation, the patient presented a purulent secretion and a spontaneous external expulsion through a fistulous channel. No claudication symptoms or hemorrhagic signs were present. The pus and device cultures were positive for Staphylococcus aureus sensitive to piperacillin/tazobac- tam. Patient management consisted of fistula drainage, systemic antibiotic the…

Tips and tricks to make the ascending aorta accessible to EVAR

2012

The ascending aorta is gaining increasing interest for endovascular specialists, as it opens the door to a potentially better way to treat aortic arch pathologies. Landing safely a stentgraft into the ascending aorta allows downgrading significantly the invasiveness of conventional open repair of the ascending aorta and/or aortic arch. Unfortunately, accessibility to the ascending aorta, in order to perform EVAR, can be challenging as the transfemoral approach might be cumbersome, or because the ascending aorta might not be appropriate for stentgraft landing. This paper will present some technical tips and tricks to achieve successful stentgraft landing in zone 0.

Collected Transatlantic Experience From the PERICLES Registry: Use of Chimney Grafts to Treat Post-EVAR Type Ia Endoleaks Shows Good Midterm Results

Multilevel diabetic foot revascularization in COVID 19 patient: Case report

2021

Abstract Introduction Coronavirus 2019 (COVID-19) has been associated with endothelial dysfunction. This hypercoagulable state coming from the endothelial injury pones COVID-19 patients to a higher risk for thrombosis. COVID 19 diabetic patients are more exposed to peripheral vascular disease progression. Multilevel peripheral arterial disease is the main cause of critical limb ischemia. Vascular interventions are required to increase distal blood flow and reduce the risk of amputation. Presentation of case We report a case of complex revascularization in a diabetic patient with aggressive right foot lesions evolution after COVID-19 infection. The patient presenting a Peripheral arterial is…
