This study describes the development of drug-loaded nanofibrous scaffolds as a nanocoating for endovascular stents for the local and sustained delivery of rosuvastatin (Ros) and heparin (Hep) to injured artery walls after endovascular procedures via the electrospinning process. PURPOSE: The proposed hybrid covered stents can promote re-endothelialization; improve endothelial function; reduce inflammatory reaction; inhibit neointimal hyperplasia of the injured artery wall, due to well-known pleiotropic actions of Ros; and prevent adverse events such as in-stent restenosis (ISR) and stent thrombosis (ST), through the antithrombotic action of Hep...

INTRODUCTION/OBJECTIVES: Endovascular repair of a proximal anastomotic pseudoaneurysm of an end-to-side aortobifemoral bypass (ABF) can lead to pelvic ischemia. We present a novel application of branched aortic endograft to repair such pseudoaneurysm while preserving flow into the ABF and native aortoiliac system. METHODS: A 71 year old male with history of aortoiliac occlusive disease resulting in lifestyle limiting claudication was treated with an aortobifemoral bypass in 1999...

TEVAR is a less invasive option for managing traumatic injuries of the descending aorta in polytraumatized patients. Concerns arise when treating young patients with TEVAR. A 22-year old male was admitted to the Emergency Department following a high-impact road traffic collision. Whole body CT scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke. We decided to treat him in an endovascular fashion with a Zenith Cook (Cook Incorporated, Bloomington, IN) endograft...

BACKGROUND: We would like to evaluate causes of Thoracic Endovascular Aortic Repair (TEVAR) failure and conversion to open surgery (COS) in high volume vascular center for open surgery, with low volume TEVAR procedures. METHODS: A total of 8 patients (6 males, mean aged 55.14 years) underwent COS after TEVAR. The indications for conversion to open surgery, intraoperative strategy, as well as early postoperative and mid follow-up results were analyzed. RESULTS: The indications for COS were persistent proximal type I endoleak with progressive aneurysm enlargement in two patients, endoleak type III in one patient, progressive aneurysm enlargement with no endoleak in one patient, stent graft migration in two patients, secondary aorto-esophageal fistula in one patient, secondary aorto-esophageal and aorto-bronchial fistula in one patient, as well as distal progression of the aneurysmal disease in 2 patient...

OBJECTIVE: After an infrapopliteal reconstruction, minor amputations are frequently required, but even in the case of successful revascularization, wound healing is a major concern. We studied the role of iliac artery inflow correction in patients undergoing infrapopliteal vein grafts to improve the heal of midfoot amputation. METHODS: Thirty-eight patients affected with Rutherford Grade III Category 5 PAD, who underwent successful simultaneous iliac endovascular procedure, infrapopliteal reversed vein bypass graft, and minor amputation, were enrolled in this retrospective study...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

BACKGROUND: Increased renal complications have been suggested with suprarenal stent grafts, but long-term analyses have been limited. Therefore, the purpose of this study was to evaluate the effect of endograft choice on perioperative and long-term outcomes. METHODS: We compared Medicare beneficiaries undergoing endovascular AAA repair from 2005-2008 with endografts with infrarenal fixation and a single docking limb (AneuRx, Excluder) to those with suprarenal fixation and two docking limbs (Zenith), or a unibody configuration (Powerlink)...

OBJECTIVE: Fenestrated and branched endovascular aneurysm repair (FB-EVAR) is a valid option to treat juxtarenal and pararenal abdominal aortic aneurysms and thoracoabdominal aortic aneurysms. Because successful deployment depends on complex maneuvers, hostile iliac artery anatomy (HIA) can prejudice the FB-EVAR outcome. The aim of the study was to evaluate the impact of HIA on FB-EVAR outcome. METHODS: Between 2010 and 2015, all patients undergoing FB-EVAR were prospectively categorized according to iliac anatomy (friendly iliac artery anatomy [FIA] or HIA)...

BACKGROUND: Aneurysms of the subclavian artery are usually the result of trauma, atherosclerosis or thoracic outlet syndrome. Until the 90s, open surgical repair was considered the only therapeutic choice, exhibiting high complication rates. Since the first report of endovascular repair of subclavian aneurysms in 1991, promising results have been published. OBJECTIVES: To summarize all available data on SA true and false aneurysm stenting in order to reach conclusions regarding morbidity, mortality and other procedure-related characteristics...

OBJECTIVE: Although the incident risk of peripheral artery disease increases in patients with metabolic syndrome, several authors report favorable outcomes in obese patients after arterial bypass surgery. We examine the effect of the so-called "obesity paradox" and metabolic syndrome on outcomes after open aortoiliac bypass surgery. METHODS: We identified patients between 2004 and 2015 who had open surgical bypass for aortoiliac occlusive disease. We excluded patients with endovascular repair and those treated primarily for aneurysmal disease...

In the last few years there has been an increase of implantable cardiac electronic device and vascular graft related infections. This is due in part to a higher complexity of some of these procedures and an increase in patient's comorbidities. Despite wide diagnosis methods availability, early stage diagnosis usually constitutes a challenge as often patients only denote insidious symptoms. In most confirmed cases, removal of the infected device is required to resolve the infection. This is mostly explainable because of bacterial ability to grow as biofilms on biomaterial surfaces, conferring them antimicrobial resistance...
