The present study investigated the incidence, causes, treatment and prevention of limb graft occlusion following endovascular aortic repair (EVAR). A total of 66 cases of abdominal aortic aneurysm receiving EVAR at our department from January 2005 to December 2013 were enrolled. After EVAR, patients received routine antiplatelet therapy of 75 mg PLAVIX for 6 months and then 100 mg Aspirin for another 6 months by oral administration. According to previous clinical experiences, antiplatelet therapy is able to effectively reduce the incidence of iliac occlusion after EVAR...

Robotic technology has been utilized in cardiovascular medicine for over a decade, and over that period, its use has been expanded to percutaneous coronary and peripheral vascular interventions. The safety and feasibility of robotically assisted percutaneous cardiovascular interventions has been demonstrated in studies including simple to complex coronary lesions, and both iliac and femoropopliteal lesions. These reports have shown that robotically assisted PCI significantly reduces operator exposure to harmful ionizing radiation without a detrimental effect on procedural success or clinical efficacy...

A 74-year-old patient presented with recurrent aneurysms in the infrarenal abdominal aorta and right common iliac artery 6 years after endovascular aortic repair using endografts in the same location. The patient underwent an aorto-bi-iliac replacement with removal of the stent graft. Two holes measuring 2 mm each were found in the removed graft, and they appeared to have been caused by wear from continuous friction between the endograft and the aortic wall.

Complexity of the spatial configuration of an aortic implant with bifurcation in the distal part is related to changes in blood hemodynamic in the area of bifurcation which may disturb blood flow and lead to thrombus formation. This study was designed to characterize parameters which define spatial configuration of an aortic implant for which the risk of thrombus formation is the smallest. We used AngioCT data from 74 patients, aged 55 ±10 years, after endovascular procedure to prepare 3D geometries of stent-grafts...

We evaluated safety and long-term outcome of endovascular therapy for steno-occlusive iliac artery disease. All endovascular procedures of iliac artery lesions performed at our institution between 2001 and 2014 (n = 676) were retrospectively analyzed. The overall technical success rate was 99% and yielded 100% for stenoses (n = 596) and 95% for chronic total occlusions (n = 80). Lesion complexity defined by the Trans-Atlantic Inter-Society Consensus (TASC) II classification had no impact on success rates (TASC A + B vs C + D; 99...

We evaluated the effects of changes in blood flow due to abdominal aortic aneurysm (AAA) surgery by using a simple zero-dimension model and applied theoretical values to clinical data.The zero-dimension electronic circuit model and diagram of blood flow distribution were created by setting the resistance of the aorta, bilateral iliac arteries, renal arteries, and aneurysm. Resistance of the aneurysm and resistance of the aorta before surgery were compared with that of the aorta after surgery. We set the radius length of each anatomical parameter to calculate theoretical values...

Iliac arterial disease, unfavorable anatomy, and prior stenting all pose challenges to access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR). Iliac access injury during T/EVAR may lead to rupture, dissection, thrombosis, or distal ischemia. Some have advocated iliac stent prior to T/EVAR in patients with suboptimal iliac access. The rate of complication and iliac stent migration during subsequent T/EVAR is undocumented. This case report describes a unique instance of self expanding iliac stent migration during TEVAR which pinched the thoracic aortic endograft causing functional aortic coarctation...

BACKGROUND: The first-line recommendation for treatment of acute iliofemoral deep vein thrombosis (IFDVT) is catheter-directed or pharmaco-mechanical thrombolysis (CDT/PCDT). Recent analysis of surgical thrombectomy has shown comparable results. However this procedure is not commonly given as much importance as interventional techniques. We analyzed patient outcome of surgical thrombectomy using modern endovascular techniques in both the short and long term. METHODS: All consecutive patients who underwent surgical thrombectomy at our institution between April 2008 and April 2017 were included...

BACKGROUND: Severe aorto-iliac occlusive disease (AIOD) is traditionally treated with aorto-bifemoral (ABF) or aorto-unifemoral (AUF) bypass. However, cross-femoral bypass (CFB) and hybrid femoral endarterectomy and patch angioplasty with iliac stenting (EPS) have gained popularity as less invasive options. We sought to compare 1-year survival, primary patency, and major amputation rates between open surgical (ABF and AUF) and two less invasive reconstruction techniques (CFB and EPS) using a large, multicenter cohort...

We describe a rare case of acute type B dissection causing collapse of a previously placed infrarenal stent-graft, resulting in acute limb ischemia due to left iliac limb thrombosis in a 59-year-old male. The patient presented with acute back and abdominal discomfort radiating to his back, bilateral buttock stabbing discomfort, and left> right thigh and calf rest pain. CTA showed a spiral type B dissection with collapse of the proximal portion of the EVAR device and left limb occlusion. Urgent treatment with TEVAR distal to the left subclavian covered the entry tear and redirected the majority of the flow to the true lumen leading to near immediate expansion of the proximal portion of the EVAR device...

OBJECTIVE: To assess the first results of hybrid operations in chronic venous obstructions of iliofemoral segments in patients with postthrombotic syndrome (PTS). METHODS: Hybrid operations (open endovenectomy from the common femoral vein with arteriovenous fistula creation and iliac vein stenting) were performed in 12 patients diagnosed with PTS. All of the patients were diagnosed with severe chronic venous insufficiency. The degree of manifestations of PTS was assessed by means of the Villalta score 7 months before and after the surgical intervention...

Background Iliac vein stenting has emerged as a therapeutic option in chronic venous disease. The optimal stent size is unknown but should match normal caliber at a minimum. Methods Teleology: The iliac-femoral outflow caliber was measured by Duplex in healthy volunteers to determine normal caliber. Patient IVUS data: The distribution curve of IVUS planimetry data in 345 chronic venous disease limbs was analyzed: values at the right tail end of the curve should approach normal values according to distribution theory...

The decision-making process for treatment of patients with end-stage renal failure, multiple failed renal transplants, and severe comorbidities can be exceedingly difficult due to the inapplicability of many common surgery methods. In this article, we report the treatment of such a patient who underwent a third renal transplant and subsequently developed a ureteral stenosis. The third kidney had been transplanted with a high abdominal position and a partially intra- and retroperitoneally placed ureter due to a bilaterally obtained iliac fossa and severe abdominal adhesions...
