BACKGROUND: Few investigators have described en bloc resection of non-small cell lung cancer (NSCLC) invading the aorta. AIM OF STUDY: Analysis of outcome and prognostic factors for en bloc resections of NSCLC invading the aorta. METHODS: Thirty-five patients (27 males, 8 females; mean age 63 ± 8.6 years) were operated between 1994 and 2015 in four European Centers. HISTOLOGY: 12 (34.3%) squamous cell carcinoma, and 6 (17...

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...

OBJECTIVE: To achieve an optimal sealing zone during endovascular aneurysm repair, the intended positioning of the proximal end of the endograft fabric should be as close as possible to the most caudal edge of the renal arteries. Some endografts exhibit a small offset between the radiopaque markers and the proximal fabric edge. Unintended partial renal artery coverage may thus occur. This study investigated the consequences of partial coverage on renal flow patterns and wall shear stress (WSS)...

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: TEVAR has dramatically expanded treatment options for patients with thoracic aortic pathology. The interaction between endografts and the dynamic anatomy of the thoracic aorta is not well characterized for repetitive physiologic stressors and subsequent issues related to long-term durability. Through 3D modeling we sought to quantify cardiac-induced aortic deformation before and after TEVAR to assess the impact of endografts on dynamic aortic anatomy. METHODS: Eight patients with acute (n = 4) or chronic (n = 3) Type B dissections, or chronic arch aneurysm (n = 1), underwent TEVAR with a single (n = 5) or multiple (n = 3) Gore C-TAG(s)...

The aim of this report is to describe the imaging and successful treatment of an acute shrinkage of the Ovation Abdominal Stent Graft System. The Ovation Prime system utilizes a polymer-filled sealing ring that is cast in situ at the margin of the aneurysm; however, the residual endograft inner volume after ring filling may reduce volume and graft flow. Nevertheless, there are no reports about severe complications using the Ovation Prime system. A 75-year-old male presented to our hospital for acute lower limb ischemia...

INTRODUCTION: Infectious complications after FEVAR cause significant problems, with radical surgery considered to be the last resort for treatment. CASE REPORT: A 72 year old man presented with infection 1 month after FEVAR. Conservative therapy with percutaneous abscess drainage and antibiotics suppressed the infection for 10 months; however, when new peri-aortic abscesses developed, the patient agreed to revision surgery. The endograft was explanted and an autologous in situ venous reconstruction was performed...

Mural thrombus in non-atherosclerotic or aneurysmatic thoracic aorta is a relatively uncommon entity. Currently there is no consensus on the appropriate therapeutic algorithm of its management. We aim to present the current knowledge on the treatment of thoracic aorta mural thrombi (TAMT) in minimally atherosclerotic vessels and we hope that the juxtaposed discussions will shed light on the uncharted waters regarding this rare syndrome. The MEDLINE/PubMed database was searched for publications with the medical subject "aortic mural thrombus" and keywords "thoracic", "embolism", "normal vessel", "minimally atherosclerotic vessel" or "treatment"...

Traditional therapeutic options for complex thoracoabdominal aneurysm include open repair, hybrid repair or endovascular repair (involving fenestrated or branched endografts). The Streamliner Multilayer Flow Modulator has been available for treatment of thoracoabdominal aneurysms since 2010. Its design permits blood flow to perfuse through the mesh in a modus that preserves collateral branch patency, while modulating turbulent to laminar flow within the device. The flow then stagnates over time within the surrounding aneurysm sac...

A 74-year-old patient presented with recurrent aneurysms in the infrarenal abdominal aorta and right common iliac artery 6 years after endovascular aortic repair using endografts in the same location. The patient underwent an aorto-bi-iliac replacement with removal of the stent graft. Two holes measuring 2 mm each were found in the removed graft, and they appeared to have been caused by wear from continuous friction between the endograft and the aortic wall.

INTRODUCTION: Neck enlargement is well described in patients treated with self-expandable endografts for abdominal aortic aneurysms. Double endografting (ie, overlapping of stent grafts) occurs in patients with proximal cuffs or bifurcated to monoiliacal configuration conversions. When the aortic neck of patients receives 2 suprarenal fixation endografts, it may behave differently in terms of radial force and interaction of additional suprarenal stents extending to the visceral aorta...

BACKGROUND: Previous studies comparing endografts with suprarenal and infrarenal fixation for endovascular abdominal aortic aneurysm repair (EVAR) have found conflicting results and did not account for differences in patient selection. This study aims to evaluate the differences in outcomes among surgeons who routinely use either suprarenal or infrarenal fixation, as well as all surgeons in the Vascular Study Group of New England (VSGNE). METHODS: All patients undergoing EVAR in the VSGNE from 2003 to 2014 were identified...

PURPOSE: The in situ fenestration of a standard endograft is currently limited by difficulties in targeting the fenestration site under fluoroscopic control and by the lack of a safe method to perforate the graft. Evidence in the literature suggests the use of a 3 D electromagnetic navigator to accurately guide the endovascular instruments to the target and a laser to selectively perforate the graft. The aim of this work is to provide design guidelines to develop a sensorized catheter to guide the laser tool to the fenestration site and conduct preliminary testing of the feasibility of the proposed solution...
