BACKGROUND: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. METHODS: From August 2009 to May 2015, 14 patients with AAAs and coexisting IAAs underwent repair with a bifurcated-bifurcated approach...

OBJECTIVE: Comparing costs between centers is difficult because of the heterogeneity of vascular procedures contained in broad diagnosis-related group (DRG) billing categories. The purpose of this pilot project was to develop a mechanism to merge Vascular Quality Initiative (VQI) clinical data with hospital billing data to allow more accurate cost and reimbursement comparison for endovascular aneurysm repair (EVAR) procedures across centers. METHODS: Eighteen VQI centers volunteered to submit UB04 billing data for 782 primary, elective infrarenal EVAR procedures performed by 108 surgeons in 2014...

Purpose. To investigate the reproducibility of aortic distensibility (D) measurement using CT and assess its clinical relevance in patients with infrarenal abdominal aortic aneurysm (AAA). Methods. 54 patients with infrarenal abdominal aortic aneurysm were studied to determine their distensibility by using 64-MDCT. Aortic cross-sectional area changes were determined at two positions of the aorta, immediately below the lowest renal artery (level 1.) and at the level of its maximal diameter (level 2.) by semiautomatic segmentation...

Type IIIb endoleak usually occurs years after the initial endograft implantation and the cause is the chronic fatigue of the endograft. This rare case describes a type IIIb endoleak, appearing immediately after deployment of a new generation low profile stentgraft and highlights the diagnostic and treatment challenges associated with the type IIIb endoleak. A 74 years old man underwent elective EVAR for an infrarenal abdominal aortic aneurysm. A type IIIb endoleak near to the flow divider due to a fabric defect was diagnosed...

This report presents the surgical repair and postsurgical outcomes following a ruptured infrarenal aortic aneurysm with a maximum transverse diameter of 20 cm. Its association with acute lower limb motor deficit is rare. Open surgery of giant abdominal aortic aneurysms is often the only available treatment, favored over an endovascular approach in the presence of increased aneurysm size with dislodged abdominal organs, adhesions, and short and angled proximal infrarenal aortic neck, presenting significant additional surgical and anesthesiological challenges...

Tumor involvement of the inferior vena cava (IVC) by hepatobiliary, pancreatic or duodenal malignancies can compromise adequate resection. However, radical resection with negative histological margins remains the only chance of cure. Various techniques are used for venous reconstruction, using a prosthetic graft interposition in most of the cases. However, in case of associated digestive resections, such as pancreaticoduodenectomy, postoperative complications can be responsible for prosthesis infection and related vascular complications...

OBJECTIVE: The aim of this study was to report the technical aspects and outcomes of late open conversion (LOC) after endovascular aneurysm repair (EVAR) in a single center by using exclusively infrarenal clamping of the endograft as an alternative to suprarenal or supraceliac aortic clamping. METHODS: A retrospective analysis of EVAR requiring late explantation (>30 days) from January 1996 to October 2016 was performed. Patients' demographics, type of endograft, duration of implantation, reason for removal, extent of stent graft removal, type of reconstruction, 30-day mortality, postoperative complications, and long-term survival were obtained for analysis...

BACKGROUND: Although recent guidelines recommend endovascular aneurysm repair (EVAR) for robust younger patients, we have been limiting our indication to older patients or those who are physically frail. This study compares long-term outcomes of our series of abdominal aortic aneurysms (AAAs) treated with endovascular repair (ER) and open surgery (OS), using propensity score matching. METHODS: Between June 2007 and October 2014, 819 patients with infrarenal AAA underwent elective repair at our institution...

Shivali Marketkar, Mark LeGolvan
IgG4 aortitis is one of the entities seen in the spectrum of IgG4-related disease (IgG4-RD). It is characterized by serologic (elevated serum IgG4) and histologic features including a lymphoplasmacytic infiltrate with increased numbers of IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. Some studies have described a correlation between infections and IgG4 aortitis. We describe a patient with an aneurysm of the infrarenal descending abdominal aorta with features of IgG4-RD, as well as culture evidence of Streptococcus sanguis...
