Tomomi Nakajima, Masataka Sato, Akito Imai, Yasunori Watanabe
A 79-year-old man underwent endovascular repair for abdominal aortic aneurysm (AAA), and both internal iliac arteries (IIAs) were preserved. Postoperatively, loss of appetite developed. On the fifth day, computerized tomography (CT) showed inferior mesenteric artery thrombus formation, necrosis of the descending colon and rectum, and generalized peritonitis. The endovascular devices had not migrated. A colonic resection was performed. Histological analysis confirmed intestinal necrosis associated with mesenteric thrombus...

We herein report a successful repair of an internal iliac artery aneurysm in a renal transplant patient. At renal transplantation, the main renal artery and accessory renal artery had been anastomosed to the right internal iliac artery and right external iliac artery, respectively. The patient underwent resection and graft replacement of the iliac artery aneurysm with reattachment of the main renal artery to the right external iliac artery through a midline laparotomy with repeated topical cold perfusion for renal protection...

Introduction: Abdominal aortic aneurysm has a lower incidence in the female population, but a higher complication rate. It was been hypothesized that some anatomical differences of abdominal aortic aneurysm in women could be responsible for that. We proposed to analyze our data to understand the differences in the clinical and anatomical characteristics and the outcomes of patients undergoing endovascular aneurysm repair, according to gender. Methods: A retrospective analysis of patients undergoing endovascular aneurysm repair between 2001-2013 was performed...

BACKGROUND: Iodine contrast medium (ICM) is considered gold standard in endovascular procedures, but nephrotoxicity and hypersensitivity limit its widespread use. Carbon dioxide (CO2) is considered an alternative for endovascular procedures in patients with contraindication to ICM. However no studies have compared the outcomes of EVAR (endovascular aneurysm repair) performed with ICM or CO2 in patients with no contraindication to ICM. METHODS AND RESULTS: From May 2012 to April 2014, 36 patients with abdominal aortic aneurysms underwent EVAR in a prospective, randomized and controlled study...

BACKGROUND: To evaluate the impact of iliac artery's diameters, tortuosity, and peripheral vascular patency on outcome of elective endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) in 2 high volume vascular centers' experience. METHODS: A retrospective study was conducted on a prospectively collected database between 2010 and 2012. Anatomical features at pre-operative computed tomography (CTA) considered as potentially influencing outcomes were: iliac diameters, tortuosity (expressed as a ratio), and calcifications, bilateral internal iliac artery (IIA) patency, and presence of Trans-Atlantic Inter-Societies Consensus (TASC) II C/D femoro-popliteal occlusive disease (PAD)...

Pregnancy-related rupture of an arterial aneurysm is an unusual occurrence associated with increased risk of morbidity and mortality. Various pregnancy-related physiologic changes appear to make pregnancy a high-risk situation for rupture of either preexisting arterial aneurysms or those that develop throughout the course of pregnancy. Splenic artery aneurysms are the most common (60%), followed by hepatic (20%), superior mesenteric (5.9%), celiac (4%), ovarian, uterine, and renal (<2%) artery. Even rarer are aneurysms involving the internal iliac artery and its branches, to which there is only one published case report...

A 77-year-old man with a history of stent implantation in the right common iliac artery(CIA) and the left external iliac artery(EIA) was admitted to our hospital for a rapid growth of an aneurysm( max 53 mm) at Th11 level of the descending aorta. Although thoracic endovascular aortic repair (TEVAR) was required, there were many problems about access rout. The infrarenal abdominal aorta and the left EIA were severely calcified, and the lumens of the right CIA stent(5.3 mm) and the left EIA stent( 4.3 mm) were small in size...

Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leakage forming a pseudoaneurysm within the hematoma...

OBJECTIVE: Internal iliac artery aneurysms (IIAA) are rare, representing only 0.3% of aortoiliac aneurysms. Its treatment with open surgery is complex and associated with high morbidity and mortality, which led to increasing application of endovascular solutions. In this study, we aimed to evaluate outcomes of endovascular aneurysm repair (EVAR) of IIAA in one institution. METHODS: We retrospectively reviewed all cases of IIAA treated with endovascular techniques between 2003 and 2014...

The accuracy and usefulness of computed flow data in an artery is dependent on the initial geometry, which is in turn dependent on image quality. Due to the resolution of the images, smaller branching arteries are often not captured with computed tomography (CT), and thus neglected in flow simulations. Here, we used a high-quality CT dataset of an isolated common iliac aneurysm, where multiple small branches of the internal iliac artery were evident. Simulations were performed both with and without these branches...

Repair of isolated iliac aneurysm with stentgraft implantation and internal iliac coverage may induce significant type ll endoleak from patent internal iliac refilling leading to ongoing aneurysm growth. Subsequent treatment of such complication can be challenging especially in case of bilateral iliac involvement. Open repair is technically demanding and often high risk procedure, while embolization via transfemoral approach is unviable due to the stentgraft coverage precluding direct antegrade access between the common and the internal iliac lumen...

INTRODUCTION: 40% of the abdominal aortic aneurysms (AAA) present an extension to the iliac axes. The access to a distal neck requiring an embolization of the iliac internal artery (AII) may cause buttock claudication, colic ischemia, perineal necrosis, erectile dysfunction and spinal cord ischemia. The aim of the branched iliac stentgrafts is to preserve pelvic vascularization while adapting to the constraints of arterial tortuosity which generate type Ib endoleaks, plications and limb thromboses...

INTRODUCTION: An increasing number of Abdominal Aortic Aneurysms (AAA) may occur in renal failure patients waiting for kidney transplantation because of sharing atherosclerotic risk factors. There is increasing possibility to diagnose an AAA in this group, which treatment has some particularities. After aneurysm's treatment these patients remain candidates to kidney transplantation. Similarly there is an increasing possibility to diagnose AAA in kidney transplantation recipients. Our aim is present our experience and review the published literature...

PURPOSE: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) involving the common iliac artery requires extension of the stent-graft limb into the external iliac artery. For this procedure, internal iliac artery (IIA) embolization is performed to prevent type II endoleak. In this study, we investigated the frequency and risk factor of buttock claudication (BC) in patients having interventional embolization of the IIA. MATERIALS AND METHODS: From January 2010 to December 2013, a total of 110 patients with AAA were treated with EVAR in our institution...

BACKGROUND: Current threshold recommendations for elective abdominal aortic aneurysm (AAA) repair are based solely on maximal AAA diameter. Peak wall stress (PWS) has been demonstrated to be a better predictor than AAA diameter of AAA rupture risk. However, PWS calculations are time-intensive, not widely available, and therefore not yet clinically practical. In addition, PWS analysis does not account for variations in wall strength between patients. We therefore sought to identify surrogate clinical markers of increased PWS and decreased aortic wall strength to better predict AAA rupture risk...

UNLABELLED: Vascular complications after kidney transplantation are uncommon, and in most cases they present in the early post-transplant period. Anastomotic pseudo-aneurysms usually involve the renal transplant artery anastomosis and in most cases are the consequence of a mycotic contamination during organ recovery or handling of the graft. We report the case of a 61 year-old woman, who presented, eight months after successful kidney transplantation from a deceased donor, with mild pain in the right iliac fossa...
