PURPOSE: To present the clinical outcome of endovascular sealing of abdominal aortic aneurysms (EVAS) with the Nellix endoprosthesis in patients with abdominal aortic aneurysms treated in our institution. METHODS: This was a retrospective, single centre, observational cohort study. A departmental database was interrogated in order to extract demographics, clinical information and outcome of all patients treated with EVAS between December 2013 and December 2015. Outcome measures included technical success (successful device deployment and absence of any endoleak at completion angiography), mortality, major complications, incidence of endoleaks, aneurysm rupture and reintervention...

OBJECTIVE: To assess for regional variation in the incidence of postoperative myocardial infarction (POMI) following non-emergent vascular surgery across the United States in order to identify potential areas for quality improvement initiatives. METHODS: We evaluated POMI rates across 17 regional Vascular Quality Initiative (VQI) groups comprised of 243 centers with 1,343 surgeons who performed 75,057 vascular operations from 2010-2014. Four procedures were included in the analysis: carotid endarterectomy (CEA, n=39,118), endovascular abdominal aortic aneurysm (AAA) repair (EVAR, n=15,106), infra-inguinal bypass (INFRA, n=17,176), and open infra-renal AAA repair (OAAA, n=3,657)...

OBJECTIVES: High-mobility group box 1 (HMGB-1) is a key substance mediating inflammation and development of atherosclerotic lesions (AL), including abdominal aortic aneurysms (AAA). Serum levels of HMGB-1 are increased in patients with AAA than in normal controls because the ALs in AAAs secrete HMGB-1. We therefore postulate that the serum HMGB-1 level should decrease after endovascular aortic repair (EVAR) or open aortic repair (OAR). However, there is no evidence of this in the literature...

Endovascular aneurysm repair (EVAR) actually represents the treatment of choice for most patients affected by aneurysm of the abdominal aorta (AAA). However, the feasibility of EVAR depends on anatomical characteristics of abdominal aorta and ilio-femoral axis. We present the case of a 82-years old man affected by severe left hydronephrosis, kidney and ureteral tumor requiring nephrectomy, that presented also a very voluminous AAA with a large diameter (96 mm), presenting also with a large proximal neck (39 mm) and with a severe angulation of the proximal neck (> 60°)...

Several studies have suggested that surgical procedures performed at high-volume centers may result in superior outcome. Technically more demanding procedures such as aortic aneurysm repair appear to demonstrate a stronger relationship with volume. The present chapter reviewed the literature using the MEDLINE database to identify studies investigating the effect of volume in aortic aneurysm repair outcomes. The great majority of studies identified shows an advantage for high-volume hospitals with regard to perioperative mortality of abdominal (AAA), thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysm repair...

BACKGROUND: The risk of long-term complications after endovascular aneurysm repair (EVAR) is still higher than open surgery and is a critical issue. This study aims to make available reliable statistical predictive models of complications after EVAR. METHODS: Two hundred and thirteen patients who underwent EVAR between 2002 and 2012 were included in this study. The preoperative CT-scans were analyzed with a dedicated workstation to provide spatially correct 3-dimensional data...

AIM: To report early and mid-term results of endovascular repair of thoraco-abdominal aneurysms (TAAA) by using of Cook-Zenith fenestrated/branched endografts (FB-EVAR) in high-surgical risk patients unfit for open repair (OR). METHODS: Between January 2012 and April 2015, all the patients with TAAA, considered at high-surgical risk for OR and treated by Cook-Zenith FB-EVAR, were prospectively enrolled. Patients were studied using a thoraco-abdominal computer tomography angiography (CTA) and dedicated software for advanced vessels analysis...

: Closure of the proximal tear by Thoracic Endovascular Aortic Repair (TEVAR) at the acute phase appears to be an safe effective treatment to prevent aneurysmal degeneration type B dissection. However, it appears to be inefficient in up to a third of the patient. We report the technical aspects of our experience with patients undergoing secondary open repair after TEVAR for dissecting thoraco-abdominal aneurysm despite early closure proximal tear by TEVAR. METHODS: During a period of 5 years, 96 patients presenting acute Type B Aortic Dissections (TBAD) were treated by TEVAR and followed-up in our institution...

OBJECTIVES: The aim of the present study was to explore whether preoperative white blood cell count (WBC) may predict 30-day mortality and long-term survival following surgery for abdominal aortic aneurysm (AAA). Secondarily we wanted to assess the potential sex differences in WBC in these patients. MATERIAL AND METHODS: The study was carried out as a retrospective cohort study. Patients undergoing surgery for intact and ruptured AAA at our institution consecutively in the time-period 1994-2007 were included...

OBJECTIVE: The Vascular Study Group of New England (VSGNE) requires documentation of follow-up for >80% of patients at least 9 months post-procedure. However, many participating groups fall short of this goal. We sought to identify factors independently associated with loss to long-term follow-up (LTF). METHODS: The VSGNE was queried from 2008-2012, for all carotid endarterectomy (CEA), endovascular aneurysm repair (EVAR), open abdominal aortic aneurysm repair (OPEN), infrainguinal bypass (INFRA), and suprainguinal bypass (SUPRA) procedures in patients who survived greater than 9 months post-procedure...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

INTRODUCTION: Abdominal compartment syndrome (ACS) after endovascular repair (EVAR) of rupture abdominal aortic aneurysm (rAAA) is a rare emergency situation, which has a high mortality. However, the progression of ACS is rapid and the diagnosis is usually been delayed, which increase the difficulties in treatment and affect the prognosis. We describe a case of a sever complication (acute intestinal necrosis) resulting from ACS after endovascular repair of rAAA. CLINICAL FINDING: An elderly man, 81 years old, complained a sudden lower abdominal and back pain without any predisposing cause...

BACKGROUND: Ovation Aortic Stent-Graft System is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid ancored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new desing . Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the Ovation in 3 patients...
