Although endovascular aneurysm repair (EVAR) in the abdominal aorta has reduced the perioperative mortality when compared with open repair, the need for reintervention after complications such as endoleak may be presented in up to 20% of the cases. Type II endoleak from branch vessels is often benign but can potentially be associated with progressive abdominal aortic aneurysm growth and sac expansion. We present a rare case of a patient who presented with sac expansion and psoas hematoma due to Type II endoleak from "unusual" collaterals of IMA and was treated successfully with endoleak microembolization and percutaneous decompression of the hematoma...

BACKGROUND: Abdominal aortic aneurysm surgery with suprarenal cross-clamping is often associated with renal injury. Although the mechanism underlying such injury is unclear, tissue ischemia and reperfusion, which induces endothelial dysfunction and decreases the availability of tetrahydrobiopterin (BH4), may play a role. We evaluated whether BH4 administration prevents renal ischemia/reperfusion injury in an animal model of aortic cross-clamping. METHODS: Nineteen anesthetized, mechanically ventilated, and invasively monitored adult sheep were randomized into 3 groups: sham animals (n = 5) that underwent surgical preparation but no aortic clamping; an ischemia/reperfusion group (n = 7), where the aorta was clamped above the renal arteries for 1 hour, and a BH4 group (n = 7), in which animals received 20 mg/kg of BH4 followed by aortic cross-clamp for 1 hour...

OBJECTIVE: Our aim was to assess the short-term impact of centralization on the outcomes of patients undergoing abdominal aortic aneurysm repair in a vascular network in the South West of England. BACKGROUND: The centralization of vascular services has been implemented nationally across the National Health Service to improve patient outcomes. The full impact of these major changes has not yet been fully analyzed. METHODS: A retrospective cohort study examining outcomes of patients undergoing abdominal aortic aneurysm repair, based on prospectively entered National Vascular Registry data, pre and post centralization in the South West of England...

Although most type II endoleaks are self-limiting, the most common indication for secondary intervention after endovascular aneurysm repair (EVAR) is type II endoleak. However, it is still debatable when to treat them. Furthermore, different intervention techniques are available to treat type II endoleaks. The aim of this review is to look at current evidence and updates on type II endoleaks after EVAR for abdominal aortic aneurysm and their management.

Sex differences between women and men are often overlooked and underappreciated when studying the cardiovascular system. It has been long assumed that men and women are physiologically similar, and this notion has resulted in females being clinically evaluated and treated for cardiovascular pathophysiological complications as males. Currently, there is increased recognition of fundamental sex differences in cardiovascular function, anatomy, cell signaling, and pathophysiology. NIH has enacted guidelines expressly to gain knowledge about ways the sexes differ in both normal function and diseases at the various research levels (molecular, cellular, tissue, organ, system)...

BACKGROUND: Although male gender, aging, hypertension, dyslipidemia, and smoking are common risk factors for abdominal aortic aneurysm, diabetes mellitus is an independent negative risk factor. In aneurysm tissue, matrix metalloproteinases (MMPs) expressed by activated macrophages degrades extracellular matrix proteins. In our previous experimental study, we demonstrated that the aneurysmal formation and macrophage activity were suppressed by inhibiting mimicking hyperglycemia (HG) through upregulation of glucose-sensing nuclear receptor, Nr1h2...

OBJECTIVE: We compared the management of patients with symptomatic, unruptured abdominal aortic aneurysms (AAAs) treated at a tertiary care center between two decades. This 20-year period encapsulated a shift in surgical approach to aortic aneurysms from primarily open to primarily endovascular, and we sought to determine the effect of this shift in the evaluation, treatment, and clinical outcomes of patients with symptomatic AAA. METHODS: We reviewed 1429 consecutive patients with unruptured AAAs treated at a tertiary care hospital by six staff surgeons between 1995 and 2004 (era 1) and between 2005 and 2014 (era 2)...

The aortic disease comprises a group of different pathologies of high prevalence, seriousness and ever changing by the medical and surgical investigations. Therefore cardiovascular scientific societies in USA, Europe and Asia have created Task Force on practice guidelines (PG) to develop, update and revise PG for aortic diseases. These documents issue recommendations on the diagnosis and management of different aortic diseases. The three societies agree on the recommendations about diagnostic tests and on the value of computed tomography and magnetic resonance as the main tools for the diagnosis and follow-up of aortic disease...

We report a 78-year-old man who presents progression of his aneurysmatic pathology with previous abdominal infrarenal aortic surgery 20 years later. The computed tomography (CT) scan showed proximal degeneration of the infrarenal aorta, left iliac aneurysm and a new descending thoracic aneurysm close to the aortic arch. The surgical treatment was staged in two times due to the evolution of the aneurysm measures. First, the thoracic and the infrarenal aneurysms were covered each one with endoprosthesis. Four years later the iliac disease was solved with a branched specific iliac endograft...

BACKGROUND: The introduction of endovascular aneurysm repair (EVAR) has reduced perioperative mortality after abdominal aortic aneurysm (AAA) surgery. The objective of this systematic review was to assess existing mortality risk prediction models, and identify which are most useful for patients undergoing AAA repair by either EVAR or open surgical repair. METHODS: A systematic search of the literature was conducted for perioperative mortality risk prediction models for patients with AAA published since 2006...

Late collapsing of a stent graft is an extremely rare event, with one existing report describing this phenomenon. A 65-year-old man with a history of endovascular aortic repair for an abdominal aortic aneurysm presented with paraplegia and bilateral lower limb ischaemia. Contrast-enhanced computed tomography showed a dissection of the descending thoracic aorta and a collapsed stent graft, resulting in bilateral lower limb ischaemia. Subsequent axillo-bifemoral bypass resolved his lower extremity functions. The patient required haemodialysis due to acute kidney failure...

Laparoscopic surgery (LS) is the minimally invasive alternative to open surgery and endovascular approach for treating major aortic diseases. Only few reports in the literature describe the long-term outcomes of the laparoscopic approach for major vascular diseases. Furthermore, the widespread use of endovascular techniques has limited the use of LS to wellselected patients. This review evaluated the results of LS for aortic disease and compared the clinical outcomes of laparoscopic technique with those of open and endovascular surgery...

L-shaped kidney is a congenital anomaly. The disorder results in the kidney appearing very similar in shape to horseshoe kidney (also a congenital anomaly), but either the right or left kidney is located at a position lower than the other kidney. In this report, we describe a woman with L-shaped kidney, identified during anatomical dissection, and compare the findings with clinical data obtained before her death. We discuss the embryology of L-shaped kidney based on detailed anatomical data on the kidney and its vascular system obtained by means of gross anatomical, radiological, and histological examinations...

OBJECTIVE: Treatment reality of abdominal aortic aneurysm (AAA) is changing. Up to date, approximately 65% of intact AAA and 30% of ruptured AAA are treated endovascularly. As most comparative studies focus upon mortality and few major complications, some outcomes as lower extremity ischemia (LEI) after invasive AAA repair are often underreported. However, there is evidence for a worse outcome of patients suffering from this kind of complication. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) vascular surgery targeted module from 2011 to 2014, we identified all patients undergoing endovascular aortic repair (EVAR) and open aortic repair (OAR) for AAA to illuminate the incidence and outcome of LEI after AAA repair...

INTRODUCTION: Abdominal aortic aneurysm (AAA) is a prevalent disease affecting around 5% of the population over 65 years of age. The exact etiology and physiopathology of AAA still raises questions and elective surgery is currently the only treatment option for this often progressive disease. In this study we hypothesized and tested a pathophysiological model that depicts AAA as an inflammation triggered autoimmune disease with remnant vessel wall peptide fragments as the antigen. MATERIAL AND METHODS: A pilot study with male AAA patients (n=14) and male controls (n=8) was conducted...

The Open versus Endovascular Aneurysm Repair trial is the only randomized controlled trial that is funded by the federal government to evaluate the treatment outcomes of infrarenal abdominal aortic aneurysms. Since the initial publication, multiple post-hoc analyses have become available. This review summarizes these data, focusing on the primary outcome measures (ie, overall survival) and several key secondary outcomes including aneurysm-related death, age consideration, secondary procedures, and endoleaks...
