We report the case of a 61-year-old obese male patient in whom we found a well-functioning 33-year-old Starr-Edwards aortic prosthesis during repeat aortic surgery. Rather than explant the prosthesis, we remodeled the aortic root, almost completely removing the aortic sinuses and leaving only a pillar of aortic tissue around the coronary ostia. The proximal end of a Hemashield tube-graft was then scalloped to accommodate the remaining aortic tissue. The patient's heart function was excellent after his weaning from cardiopulmonary bypass...

A mycotic aneurysm that also involves the visceral arteries is a life-threatening condition. Surgical management typically consists of débridement and in situ repair with a Dacron graft and reimplantation of the involved visceral branches. We report a rare case of a mycotic saccular thoracoabdominal aortic aneurysm involving the celiac artery, with Streptococcus pneumoniae as the responsible organism. Successful repair of the aneurysm and concomitant revascularization of the celiac artery were achieved.

PURPOSE: To evaluate the feasibility, safety, and outcome of transcatheter embolization using ethylene vinyl alcohol copolymer (EVOH) of type I endoleaks associated with endovascular abdominal aortic aneurysm repair. PATIENT POPULATION AND METHODS: Retrospective chart review was performed to identify 8 consecutive patients who had undergone EVOH embolization for type I endoleaks between 2012 and 2015. The primary approach used to access the endoleak was the perigraft technique, where the endoleak itself is catheterized at the anastomotic site...

BACKGROUND: Compared to open thoracoabdominal aortic aneurysm (TAAA) repair, hybrid repair is thought to be less invasive with better perioperative outcomes. Due to the extent of the operation and long recovery period, studying perioperative results may not be sufficient for evaluation of the true treatment effect. The aim of this study is to evaluate 1-year mortality and morbidity in patients with TAAA undergoing hybrid repair. METHODS: In a retrospective cohort study, all medical records of patients undergoing hybrid repair for TAAA at the Erasmus University Medical Center between January 2007 and January 2015 were studied...

Abdominal aortic graft-enteric fistula is an uncommon but grave complication. Acceptable early results of its management have been reported in recent years, but aortic stump disruption remains a dreaded problem in the remote period. This report describes a case of a 71-year-old male with graft-enteric fistula following after a distant abdominal aortic aneurysm repair. The patient underwent 1-stage operation with extra-anatomic bypass preceding the complete removal of the infected aortic graft and intestinal repair...

: 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...

OBJECTIVES: To determine whether follow-up survival is better after elective endovascular aneurysm repair (EVAR) than open surgical repair (OSR) for intact abdominal aortic aneurysm (AAA), we combined 5-year survival curves themselves of EVAR and OSR in randomized controlled trials (RCTs) and propensity-score matched (PSM) studies. METHODS: Eligible studies were RCTs or PSM studies of elective EVAR versus OSR enrolling patients with intact AAA and reporting 5-year (at least) survival curves...

BACKGROUND: Follow-up computed tomography angiography (CTA) scans add considerable postimplantation costs to endovascular aneurysm repairs (EVARs) of abdominal aortic aneurysms (AAAs). By building a risk model, we hope to identify patients at low risk for aneurysm sac enlargement to minimize unnecessary CTAs. METHODS: 895 consecutive patients who underwent EVAR for AAA were reviewed, of which 556 met inclusion criteria. A Probit model was created for aneurysm sac enlargement, with preoperative aneurysm morphology, patient demographics, and operative details as variables...

OBJECTIVE: Thoraco-abdominal aortic aneurysm (TAAA) repair is a complex procedure performed in patients at high cardiovascular risk. High volume intra-operative bleeding is often recorded, and the amount of intra-operative blood product transfusion is associated with relevant morbidity and mortality. The aim of the study was to identify pre-operative predictors of intra-operative large volume blood transfusions (LVBT) to stratify patients pre-operatively. METHODS: This was a retrospective analysis of prospectively collected data of all patients who underwent open TAAA surgery at San Raffaele Scientific Institute from January 2009 to December 2015...

: Abdominal Aortic Aneurysms (AAA) involve slow dilation and weakening of the aortic wall due to breakdown of structural matrix components, such as elastic fibers by chronically overexpressed matrix metalloproteinases (MMPs), primarily, MMPs-2 and -9. Auto-regenerative repair of disrupted elastic fibers by smooth muscle cells (SMCs) at the AAA site is intrinsically poor and together with chronic proteolysis prevents restoration of elastin homeostasis, necessary to enable AAA growth arrest or regression to a healthy state...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...

BACKGROUND: Pharmacological prophylaxis has been proven to reduce the risk of cardiovascular events in individuals with atherosclerotic occlusive arterial disease. However, the role of prophylaxis in individuals with abdominal aortic aneurysm (AAA) remains unclear. Several studies have shown that despite successful repair, those people with AAA have a poorer rate of survival than healthy controls. People with AAA have an increased prevalence of coronary heart disease and risk of cardiovascular events...

OBJECTIVE: This study compared reoperation rates associated with open abdominal aortic aneurysm (AAA) repair (OR) outcomes vs endovascular AAA repair (EVAR). METHODS: A retrospective review of the Veterans Affairs Surgical Quality Improvement Project data was performed with inclusion criteria defined as all patients who underwent AAA repair from October 1, 2007, to October 1, 2013. The primary outcome was the incidence of reoperations. Reoperations included subsequent OR or EVAR procedures performed on the abdominal aorta or iliac arteries, surgical treatment of temporally related bowel obstruction, as well as treatment of abdominal or groin wound complications ≤6 months and treatment of bowel or lower limb ischemia ≤10 days...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...
