Predictive Factors of Amputation in Infrainguinal Vascular Trauma: A Monocentric Experience.

Background: Infrainguinal vascular injuries (IIVIs) are emergencies involving both functional and vital prognosis. The choice between saving the limb or doing a first-line amputation is difficult even for an experienced surgeon. The aims of this work are to analyze early outcomes in our center and to identify predictive factors for amputation.

Endovascular creation and validation of acute in vivo animal model for type A aortic dissection.

Background: Animal modeling is a prerequisite for clinical transfer of new therapies. This study targets an acute in vivo animal model of type A dissection using endovascular approach with a view to test future stent grafts dedicated to this aortic segment.

Methods: Experiments were conducted on 13 swine.

Aortic Anatomy and Complications of the Proximal Sealing Zone after Endovascular Treatment of the Thoracic Aorta.

Background: Technical and clinical success of thoracic aortic endovascular procedures relies mainly on the choice of the proximal sealing zone (PSZ). The latter can be affected by multiple complications, all of them having a potential gravity and a direct link with the quality of the PSZ. The objective of this study was to analyze the risk factors of PSZ complications occurrence.

Outcomes analysis of stent-graft repair for thoracic aorta emergencies.

Background: This study aimed to identify patient, pathology and procedure-related factors affecting perioperative and mid-term mortality of thoracic aorta emergencies.

Methods: Between 2007 and 2014, patients treated emergently with thoracic stent-graft were retrospectively reviewed. Variables analyzed were: age, renal insufficiency, shock, cardiac arrest, transfer status, pathology, debranching procedures, operation duration, vascular access and European System for Cardiac Operative Risk Evaluation (EuroSCORE).

Atheromatous occlusive lesions of the popliteal artery treated with stent grafts: predictive factors of midterm patency.

Background: Because of its location, the popliteal artery is exposed to important biomechanical constraints, inducing a specific risk of thrombosis of stents, little studied in the literature. The objective of this monocentric retrospective study was to evaluate the patency of stents implanted in the popliteal artery to treat atheromatous lesions and the risk factors predisposing to thrombosis.

Methods: Between January 2009 and July 2013, all the patients receiving stents for a residual stenosis or a complication of angioplasty in the popliteal artery or the distal anastomosis of a femoropopliteal bypass were included retrospectively and in an intention to treat.

Examination of factors in type I endoleak development after thoracic endovascular repair.

Objective: The objective of this study was to assess the effects of operative indication, anatomy, and stent graft on type I endoleak occurrence after thoracic endovascular aortic repair.

Methods: A retrospective review was conducted of patients admitted for thoracic endovascular aortic repair between 2007 and 2013. All computed tomography angiography imaging was analyzed for the presence of endoleak and measurement of diameters and lengths.

Unstable patients with retroperitoneal vascular trauma: an endovascular approach.

Background: In hemodynamically unstable patients, the management of retroperitoneal vascular trauma is both difficult and challenging. Endovascular techniques have become an alternative to surgery in several trauma centers.

Methods: Between 2004 and 2006, 16 patients (nine men, mean age: 46 years, range: 19-79 years) with retroperitoneal vascular trauma and hemodynamic instability were treated using an endovascular approach.

Renal artery thrombosis caused by stent fracture: the risk of undiagnosed renal artery entrapment.

We report a case of renal artery thrombosis resulting from a stent fracture in a patient with a solitary functional kidney. It was successfully revascularized by surgical repair despite renal ischemia lasting more than 48 hours. This article illustrates the danger of generalizing endovascular stenting in renal artery disease regardless of the etiology.

A comparison of the standard bolia technique versus subintimal recanalization plus Viabahn stent graft in the management of femoro-popliteal occlusions.

Objective: To assess the potential benefit of the addition of a covered stent to a subintimal recanalized artery in patients with femoro-popliteal occlusions.

Methods: From September 2003 to October 2005, we retrospectively analyzed all patients admitted for severe claudication or critical limb ischemia related to long femoro-popliteal occlusions and treated with subintimal recanalization. Patients were divided into two groups depending on whether they received a stent or not.
