PURPOSE: This study aims to reveal risk factors and establish a prediction model for the immediate technical failure (ITF) of endovascular treatment (EVT) in femoropopliteal occlusive disease (FPOD) patients based on preoperative clinical data. METHODS: A retrospective analysis of 1563 FPOD patients who underwent above-the-knee EVT was undertaken. Univariate analysis with Chi-square test was used to screen risk factors from preoperative clinical data. Multivariable analysis with logistic regression was used to generate a model for predicting the ITF rate of EVT, which was evaluated through the receiver operator characteristic curve and another independent cohort of 242 FPOD patients...

Long-term iliofemoral complications induced by radiation include vascular (arterial and venous) lesions, nervous lesions and soft tissue loss that can be cutaneous and subcutaneous and potentially lead to radionecrosis with vessel exposure. We present five cases of groin radionecrosis. There were three men and two women (age 30-73 years). Radiotherapy had been delivered 15 years earlier in three cases, and 2 years earlier in two cases. Symptoms were intermittent claudication (n=1), critical ischemia (n=1), and septic hemorrhage (n=1)...

Endovascular intervention is an appealing revascularization strategy for iliac artery disease. Atherectomy of the iliac artery is uncommon due to the risk of life-threatening perforation but may be necessary if the iliac lesion is heavily calcified, preventing stent delivery or optimal expansion. We assessed the feasibility and safety of orbital atherectomy for the treatment of iliac artery disease. Demographic data, lesion characteristics, and procedure outcomes for the CONFIRM patients with at least one iliac artery lesion treated with orbital atherectomy (n=62 patients; n=68 lesions) were compared to patients with at least one superficial femoral artery (SFA) lesion treated with orbital atherectomy (n=1570 patients; n=1809 lesions)...

High-definition fluoroscopic imaging is required to perform endovascular procedures safely and precisely, especially in complex cases, resulting in longer procedures and increased radiation exposure. This is of importance for training institutions as trainees, even with sound instruction in as low as reasonably achievable (ALARA) principles, tend to have high radiation exposures. Recently, there was an upgrade in the imaging system allowing for comparison of radiation exposure to patients and providers. We performed an analysis of consecutive endovascular aneurysm repair (EVAR) and superficial femoral artery (SFA) interventions in the years 2013 to 2014...

This retrospective study determined the duplex ultrasound scanning criteria for detecting 50%-69% and 70%-99% stenosis of the superficial femoral artery (SFA). Examinations of 278 limbs in 185 patients with peripheral arterial disease were performed. Duplex ultrasound scanning was used to measure the diameter of the vascular lumen, the peak systolic velocity (PSV) at the stenotic segment of the SFA (PSVst), the segment proximal to the stenosis (PSVpro) and the popliteal artery (PSVpop, distal to the stenosis)...

This study tested the hypothesis that intermittent compression of the lower limb would increase blood flow during exercise and post-exercise recovery. Data were collected from 12 healthy individuals (8 men) who performed three minutes of standing plantar flexion exercise. Three conditions were tested: no applied compression (NoComp), compression during the exercise period only (ExComp), and compression during two minutes of standing post-exercise recovery (RecComp). Doppler ultrasound was used to determine superficial femoral artery (SFA) blood flow responses...

In adult liver transplantation, renoportal anastomosis (RPA) has been introduced as a useful technique for patients with grade 4 portal vein thrombosis and a splenorenal shunt. Here, we report a pediatric case in which RPA allowed a left lateral lobe living donor liver transplantation (LDLT) despite portal vein thrombosis and a large splenorenal shunt. At 36 days old, the patient underwent a Kasai operation for biliary atresia. At 17 months old, she underwent LDLT because of repetitive cholangitis. Pretransplant examinations revealed a large splenorenal shunt and portal vein thrombosis...
