OBJECTIVE: A retrograde technique through the gap between the distal stent landing zone and the iliac artery wall has been applied to treat type II endoleak after endovascular aortic aneurysm repair (EVAR). In this study, we tried to investigate its efficacy in the management of type III endoleak and intraoperative accidental events. METHODS: We reported 2 complications of EVAR that were difficult to treat with conventional methods. One patient had a sustained type III endoleak after EVAR, and the right renal artery was accidentally sealed by a graft stent in the other patient during the operation...

Transcaval aortic access has been used for deployment of transcatheter aortic valves in patients in whom conventional arterial approaches are not feasible. This access can be vital in other situation when large bore access is needed. We described a case of 65-year-old man who had large thoracic descending aortic aneurysm with diffuse bilateral iliac disease precluding the arterial access required for the procedure. The patient underwent successful transcaval access with placement of 22-Fr balloon expandable sheath followed with successful deployments of 32 mm × 32 mm × 150 mm Valiant stent graft (Medtronic, Minneapolis, MN)...

BACKGROUND: Severe limb ischaemia (SLI) is defined as the presence of rest pain and/or tissue loss secondary to lower extremity atherosclerotic peripheral arterial disease. The superficial femoral and popliteal arteries are the most commonly diseased vessels in such patients and are being increasingly treated using endovascular revascularisation techniques. However, it is currently unknown whether drug-eluting stents and drug-coated balloons confer additional clinical benefits over more established techniques using plain balloons and bare metal stents, or whether they represent a cost-effective use of NHS resources...

Anticancer drugs are commonly used as inhibitors of vascular smooth muscle cell (VSMC) proliferation in clinical treatments. This study aims to investigate how elemene affects the proliferation of VSMCs, the restenosis, and the reendothelialization after implanting the elemene-coated stents. VSMCs derived from rat aorta were used to test the cell proliferation, cell cycle, migration, apoptosis, cytoskeletal protein F-actin, intracellular Ca(2+), IncRNA chip and gene expression of PCNA, P53, and Cx43 when cultured with elemene...

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...

An 81 year-old woman was referred for the treatment of a 79 mm-diameter short neck abdominal aortic aneurysm with highly tortuous iliac arteries. She was considered at high risk for open repair and not suitable for standard endovascular repair given the short length of the proximal neck. Delay for a manufactured custom-made fenestrated stent-graft was too long given the diameter of the aneurysm. A flexible stent-graft was preferred because of severe iliac tortuosity. Endovascular repair was performed using a physician-modified Anaconda stent-graft with one fenestration for the left renal artery...

BACKGROUND: Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB...

Aortocaval fistula (ACF) is a rare complication. Endovascular repair is an option for this fatal condition. However, endoleak and persistent fistula may occur and lead to technical failure. We performed endovascular repair for 3 cases of challenging ACF with hostile anatomy. Patient 1 was an 80-year-old man who complained of abdominal distension and lower limb edema for 15 days. He had renal and cardiac dysfunction. Computed tomography angiography (CTA) showed an ACF and extreme tortuosity of right iliac artery...

To report a case of pararenal aortic aneurysm (PAAA) with narrowed iliac arteries treated by the chimney technique combined with the INCRAFT(®) AAA stent graft system. A 75-year-old man was diagnosed with a 55mm PAAA. Patient was judged unfit for open repair and for standard endovascular repair (EVAR) due to its clinical and anatomical requirements. Custom-made fenestrated device (FEVAR) was excluded due to the presence of narrowed and heavily calcified iliac axes. Consequently, patient underwent auspicious endovascular aneurysm repair with the INCRAFT(®) System and chimney grafts in the superior mesenteric artery and both renal arteries...

Aneurysmal degeneration of distal landing zones after endovascular aneurysm repair (EVAR), can be a potential cause of late failure of this technique. Aneurysmal degeneration of common iliac arteries increases the risk of rupture of the iliac aneurysm itself as well as of the abdominal aortic aneurysm (AAA) owing to aneurysm's reperfusion as a type Ib endoleak. Reoperation consists in plugging and covering the internal iliac artery (IIA), by extension into the external iliac artery, or preservation of antegrade flow in IIA by iliac branch devices (IBD) or sandwich technique...

A 55-year-old male with a history of iliac artery - popliteal artery polytetrafluoroethylene graft bypass presented 2 years later with sudden onset gross hematuria with sepsis. Computed tomography (CT) angiography was suggestive of fistula between ureter and iliac artery which was treated with arterial covered stent graft. The patient presented 2 weeks later with watery discharge from the previous scar. CT suggested ureter-cutaneous fistula. JJ stenting of ureter was done. The patient was discharged and on follow-up CT scan, there was no evidence of fistula and patient was completely asymptomatic...
