Desarrollo de un modelo predictivo de mortalidad a largo plazo y complicaciones relacionadas con la endoprótesis, en la reparacion endovascular de an…

2015

Desde el inicio de la reparación endovascular de aneurismas de aorta abdominal infra renal, la progresión de dicho tratamiento ha superado en numero al realizado anualmente mediante cirugía abierta convencional, en la mayoría de servicios de Cirugía Vascular. A ello ha contribuido principalmente la menor mortalidad operatoria los 30 días y al atractivo que supone para pacientes un procedimiento menos agresivo y para los profesionales, el ofrecer una alternativa en casos en los que la cirugía abierta sería inasumible por elevado riesgo. Sin embargo se pueden señalar dos puntos de controversia en dicha tendencia: -La menor tasa de mortalidad postoperatoria, puede hacer que se ofrezcan alterna…

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…

Use of the directional atherectomy for the treatment of femoro-popliteal lesions in patients with critical lower limb ischemia

2016

Femoro-popliteal PTA for the treatment of critical limb ischemia is frequently associated with unsatisfactory procedural success rates while directional atherectomy (DCA) has improved success rate since claudicant patients undergoing percutaneous treatment of femoro-popliteal obstructive disease. The aim of this prospective study is to evaluate the safety, efficacy and procedural success of DCA, at one year, in the percutaneous treatment of femoro-popliteal obstructive disease in patients with critical limb ischemia.Methods. From March 2012 to March 2013 18 consecutive patients with critical limb ischemia were treated with DCA (Turbohawk/ Covidien-ev3 Endovascular Inc., North Plymouth, Minn…

Aneurysms of Vertebro-basilar Junction: a single center experience and meta-analysis of endovascular treatments

2014

Vascular lesions of the vertebrobasilar junction (VBJ) are a challenging task in neurosurgical practice, and their gold-standard therapy is still under debate. The authors describe the operative strategies currently in use for the management of those complex vascular lesions and discuss their rationale throughout a literature metaanalysis and a single center blinded retrospective study. The single center study included a review of initial presentation, angiographic features and clinical outcome (with modified Rankin Scale [mRS] scores) over a long-term follow-up. In our series, small aneurysms were effectively treated with endosaccular coils embolization; whereas a strategy including flow-d…

Mid- and Longer-term Follow up of Chimney and/or Periscope Grafts and Risk Factors for Failure

2016

Objective The aim was to report on chimney and periscope grafts (CPGs) and their mid- and longer-term outcomes when they are used to preserve reno-visceral artery (RVA) perfusion in endovascular repair of pararenal (PRAAs) or thoraco-abdominal aortic aneurysm (TAAAs). In addition, factors associated with CPG failure are presented. Limited data exist on the outcomes of CPGs, and mid- and long-term results are generally not reported. Methods This was a prospective study in a cohort of 100 patients with PRAA (69) or TAAA (31). A total of 224 (mean 2.24 per patient) RVAs were preserved with 136 (61%) chimney and 88 (39%) periscope grafts. CPGs were constructed mainly using self expandable stent…

Surgical conversion with graft salvage as a definitive treatment for persistent type II endoleak causing sacenlargement

2015

Objective The goal of this study was to present open surgical conversion with graft salvage or "semiconversion" as a definitive and safe treatment for untreatable and persistent type II endoleaks causing sac enlargement after endovascular aneurysm repair. Methods Between January 2001 and December 2014, 25 of 1623 endovascular aortic repair (EVAR) patients were selected as candidates for open semiconversion. The indication was persistent type II endoleak in 13 patients (12 of whom received previous attempts of embolization), type I and II endoleak in 2 patients, and sac growth without imaging evidence of endoleak in the other 10. After the infrarenal aorta was prepared (via a retroperitoneal…

Peroperative Intravascular Ultrasound for Endovascular Aneurysm Repair versus Peroperative Angiography: A Pilot Study in Fit Patients with Favorable …

2020

The aim of this study was to compare intravascular ultrasound (IVUS) assistance for endovascular aortic aneurysm repair (EVAR) to standard assistance by angiography.From June 2015 to June 2017, 173 consecutive patients underwent EVAR. In this group, 69 procedures were IVUS-assisted with X-ray exposure limited to completion angiography for safety purposes because an IVUS probe does not yet incorporate a duplex probe (group A), and 104 were angiography-assisted procedures (group B). All IVUS-assisted procedures were performed by vascular surgeons with basic duplex ultrasound (DUS) training. The primary study endpoints were mean radiation dose, duration of fluoroscopy, amount of contrast media…

Predilation technique with balloon angioplasty to facilitate percutaneous groin access of large size sheath through scar tissue

2017

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin acce…

TEVAR and periscope graft technique to treatment of huge aneurysm of aortic isthmus: Case report

2021

Introduction Thoracic endovascular aortic repair (TEVAR) has revolutionized the treatment of thoracic aortic aneurysms. Innovative techniques as chimney and periscope grafts can improve the outcomes of procedure. Herein, we report a case in emergency of huge Thoracic aortic aneurism. Presentation of case An 86-year-old male with hypertension, diabetes mellitus, was referred to our hospital for chest pain. CT-angiography showed a huge aneurysm of aortic isthmus with signs of rupture. The patient was considered unfit for open surgery and an endovascular approach was chosen. This patient underwent endovascular repair with TEVAR, using the periscope graft technique to preserve patency in left s…

Treatment of de novo femoro-popliteal lesions with a new Drug Coated Balloon: early experience of a single Center in the first 50 patients

2018

Angioplasty with drug-coated balloon (DCB) is an emerging and reliable method for the treatment of femoro-popliteal lesions. We report our experience with the Stellarex™ DCB in the first 50 patients. Methods - From July 2015 to November 2017, 50 patients (41 M, 9F), medium age (64 ± 7.4 year) were subject to 33 angioplasties (PTAs) for femoro-popliteal lesions with a paclitaxel-coated balloon (Stellarex™). Based upon clinical data sixteen patients had severe claudication (56% - Rutherford class 3); ten patients suffered from ischemic rest pain (34% - Rutherford class 4); and five presented minor tissue loss (10% - Rutherford class 5). 42% of patients showed femoro-popliteal lesion TASC-II B…
