Descriptive and follow-up study of patients treated surgically for abdominal aortic aneurysm at tertiary hospitals in Spain.

2019

BACKGROUND The aim of this study was to assess potential variability in the clinical characteristics and treatment of patients undergoing elective surgery for abdominal aortic aneurysm (AAA) across five hospitals in Spain. METHODS Multicenter, retrospective cohort study of patients diagnosed with AAA and treated with open surgical repair (OSR) or endovascular aneurysm repair (EVAR). We evaluated clinical and demographic variables, including comorbidity (Charlson Comorbidity Index [CCI]); anatomic characteristics; surgical risk (ASA Score); aneurysm characteristics; and in-hospital and overall mortality. All patients were followed for three years. RESULTS A total of 186 patients were include…

Multiple periscope and chimney grafts to treat ruptured thoracoabdominal and pararenal aortic aneurysms

2011

Purpose: To report midterm outcomes after urgent endovascular repair of ruptured pararenal or thoracoabdominal aortic aneurysms using multiple periscope and chimney grafts to preserve renovisceral branch perfusion and facilitate aneurysm exclusion. Methods: Nine consecutive men (mean age 72614 years, range 40–88) presenting with ruptured thoracoabdominal (n56), pararenal (n52), or infrarenal (n51) aortic aneurysm underwent urgent endovascular repair with at least 1 periscope graft delivered via a transfemoral access; chimney grafts were installed from an axillary access. In all, 17 periscope and 7 chimney grafts were used to reperfuse 11 renal and 13 visceral arteries in the 9 patients. The…

Early results of endovascular treatment of patients with bilateral stenoses of the internal carotid arteries using proximal protection systems at 30-…

2017

Abstract Background Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an very important role as alternative treatment modality, especially in patients with critical, symptomatic lesions. This study was single-centre study to evaluate the technical and clinical success of proximal protection devices as the first choice for embolic protection in symptomatic and asymptomatic carotid stenosis in patients with bilateral, advanced lesions of carotid arteries (bilateral stenoses or stenosis and occlusion). Methods This was a post hoc analysis, with 30-day follow up. We anal…

Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery

2014

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stentgraft repair of aortic transection involving an aberrant right subclavian artery (ARSA). Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability. To achieve rapid sealing and maintain perfusion to both subclavian arteries, a chimney stent to the left subclavian artery (LSA) and a periscope stent-graft to the ARSA were deployed successfully. After surgical repair of all fractures, the patient was discharged 1 month aft…

Endovascular treatment of abdominal aortic anastomotic pseudoaneurysm. The experience of two centers.

2012

INTRODUCTION: Abdominal aortic pseudoaneurysms are a rare but serious complication of aortic surgery. Treatment with traditional open surgery is associated with a high rate of perioperative mortality and morbidity. Endovascular treatment is less invasive and guarantees lower mortality and morbidity rates. The aim of this study was to evaluate the role of short-, medium- and long-term endovascular treatment of these pseudoaneurysms. MATERIALS AND METHODS: Over the past 10 years, 14 patients with abdominal aortic aneurysms, which developed after prior aortic surgery, underwent endovascular treatment involving implantation of an endoprosthesis at our institutions. Exclusion criteria were emerg…

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…

CardioPulse: developments in the treatment of aortic aneurysms in 2014

2015

Since the introduction of EndoVascular Aortic Repair (EVAR) for the treatment of abdominal aortic aneurysms (AAA) more than 20 years ago, the technique has evolved rapidly, from tubular grafts for fairly simple abdominal aortic anatomy, to bifurcated, fenestrated, branched, or parallel grafts for complex aortic aneurysms, no longer confined to the infrarenal abdominal aorta.

Thoracic Endovascular Aortic Repair (TEVAR) for the treatment of aortic diseases: a position statement from the European Association for Cardio-Thora…

2012

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease.1–4 Fundamentally, it is a far less invasive approach than open surgery and its availability and relative ease of application has changed and extended management options in thoracic aortic disease, including in those patients deemed unfit or unsuitable for open surgery. In the operating room, this requires considerable perceptual, cognitive and psychomotor demands on the operators. The dramatic expansion of TEVAR activity has necessarily prompted a requirement to systematically consider the indications, appropriateness, limitations and…

Computer Modeling for the Prediction of Thoracic Aortic Stent Graft Collapse

2011

OBJECTIVE: To assess the biomechanical implications of excessive stent protrusion into the aortic arch in relation to thoracic aortic stent graft (TASG) collapse by simulating the structural load and quantifying the fluid dynamics on the TASG wall protrusion extended into a model arch. METHODS: One-way coupled fluid-solid interaction analyses were performed to investigate the flow-induced hemodynamic and structural loads exerted on the proximal protrusion of the TASG and aortic wall reconstructed from a patient who underwent traumatic thoracic aortic injury repair. Mechanical properties of a Gore TAG thoracic endoprosthesis (W. L. Gore and Assoc, Flagstaff, Ariz) were assessed via experimen…
