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...

PURPOSE: Type II endoleaks (T2Es) remain the Achilles heel of Endovascular Aneurysm Repair (EVAR), involving a close follow-up and sometimes leading to reintervention. Identifying risk factors impacting T2Es is of concern to improve decision-making and optimize follow-up. However, it has led to contradictory results, with supporting evidence for the majority of factors being weak. METHODS: A systematic review and meta-analysis was conducted to study risk factors of T2Es following EVAR to identify risk factors and measure their dedicated strength of association...

OBJECTIVE: Alloplastic aortic graft infection is a devastating complication following aortic surgery. It is associated with excessively high mortality and morbidity caused by anastomotic rupture or septicemia. Many authors consider in situ replacement after complete surgical graft removal as the method of choice. However, there is an ongoing debate about the most suitable material for reconstruction. We present our first experiences with replacing the descending and infra-renal aorta using custom-made bovine pericardium grafts...

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...

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: Endoleaks of type Ib and III are relatively common causes of re-intervention after EVAR. The aim was to determine underlying causes and identify anatomical factors associated with these re-interventions. METHODS: A total of 444 patients with standard bifurcated stent grafts were included in a retrospective observational study. Patients requiring additional iliac stent grafts (n = 24) were compared to those who did not (n = 420). Pre- and post-operative CT examinations were reviewed in patients with additional iliac stents...
