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)...

PURPOSE: This retrospective study evaluates the effectiveness and safety of the Angio-Seal closure device in superficial femoral artery (SFA) antegrade punctures compared to common femoral artery (CFA) antegrade punctures. METHODS: Over a period of 46 months from January 2012, consecutive patients who underwent antegrade CFA or SFA punctures using Angio-Seal as a closure device in a single centre were studied. Patients were identified by reading all the individual reports on our radiology system for all patients who underwent any angiographic examination during the study period, and their individual case notes were subsequently reviewed...

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...

BACKGROUND/PURPOSE: Objective, reliable and easy monitoring of microvascular tissue perfusion is a goal that was achieved for many years with limited success. Therefore, a new non-invasive hyperspectral camera system (TIVITA™) was tested for this purpose in an in vivo animal model. METHODS: Evaluation of tissue oxygenation during ischemia and upon reperfusion was performed in left hind limb in a rat model (n=20). Ischemia was induced by clamping and dissection of the superficial femoral artery...

A 19-year-old man with mitral valve endocarditis and prolapse, intracerebral and intracerebellar hematoma, and a mycotic cerebral aneurysm underwent emergency mitral valve replacement during minimal cardiopulmonary bypass (total priming volume, 800 mL; autologous retropriming, activated clotting time <300 seconds) 1 day after undergoing endovascular coil embolization of the aneurysm. Postoperatively, there were no extensions of the intracerebral and intracerebellar hematoma. After intensive rehabilitation therapy, the patient recovered fully except for residual bilateral claudication because of preoperative bilateral embolism to both superficial femoral arteries...

BACKGROUND: The endovascular management of arterial injuries has resulted in reduced operating time, blood loss, hospital mortality, lower incidence of sepsis, and decrease in mortality rates. For penetrating trauma, however, the benefits of endovascular therapy are questionable. PATIENTS AND METHODS: Data were obtained by retrospective analysis of electronic medical records. All patients with vascular trauma seeking care at our institution from January 2010 to December 2015 were reviewed...

Crossover stenting of femoral bifurcation raises the concern of jeopardizing the deep femoral artery (DFA) entry, thereby increasing future risk of limb-threatening ischemia and amputation. This retrospective multicenter study compared clinical outcomes of crossover stenting and non-crossover stenting for ostial superficial femoral artery (SFA) lesions. We reviewed 125 limbs in 103 patients with successful stent implantation for ostial SFA lesions and allocated them to two groups, based on whether the stent crossed over the DFA orifice (CO, n = 54) or not (NC, n = 71)...

OBJECTIVE: Various animal models of critical limb ischemia have been developed in the past. However, there is no animal model that can undergo endovascular treatment, while providing reproducible true critical limb ischemia with arterial ulcers and rest pain. We evaluated the efficacy of a new model of rabbit hindlimb ischemia created through a percutaneous approach using embolization with calibrated particles. METHODS: Through a percutaneous transauricular artery approach and selective catheterization of the superficial femoral artery, embolization of distal limb vessels was performed using a mixture of 300- to 500-μm calibrated microparticles (Embosphere, Merit Medical, Salt Lake City, Utah), saline solution, and iodine contrast...

Cardiac myxomas are the most common cardiac tumors with diverse nonspecific clinical manifestations. A 78-year-old man presented to the emergency department with complaints of pain and coldness of the left lower extremity. The left femoral artery pulse was detected, while the pulses of the left popliteal, dorsalis pedis, and posterior tibialis arteries were absent. No blood inflow was detected in the superficial and deep femoral, popliteal, and anterior and posterior tibialis arteries. Thrombectomy was performed, and a fatty-like mass from the bifurcation of the common femoral artery and a thrombotic mass from the proximal portion of the superficial and deep femoral arteries were removed...

OBJECTIVES: This study sought to evaluate the safety and effectiveness of a paclitaxel-coated drug-coated balloon (DCB) for the treatment of patients with de novo in-stent restenosis (ISR). BACKGROUND: Treatment of patients with ISR remains a challenge. Current strategies are plagued by high rates of recurrent restenosis and need for reintervention. The best intervention for ISR remains to be elucidated. METHODS: The IN.PACT Global study is an independently adjudicated multicenter, prospective, single-arm study that enrolled 1,535 subjects with symptomatic atherosclerotic disease of the superficial femoral and/or popliteal arteries, including de novo ISR lesions...

We present the case of an 81-year-old female with flush occlusion of the superficial femoral artery (SFA) and percutaneous transluminal angioplasty. Initially, the antegrade approach failed due to flush occlusion without stump. Hard, round surfaced, calcific, and eccentric plaque of the ostium of SFA was also present, which involved distal common femoral artery (CFA). Thus, we successfully used a Frontrunner catheter for retrograde reentry at the lower position of the CFA. Various treatment strategies involving Frontrunner and atherectomy devices could make percutaneous procedures possible in femoropopliteal occlusive disease, involving the CFA...

INTRODUCTION: Acute aerobic exercise prevents sitting-induced impairment of flow-mediated dilation (FMD). Further, evidence suggests that sitting-induced impairment of FMD occurs via an oxidative stress-dependent mechanism that disrupts endothelial function. PURPOSE: We hypothesized that acute aerobic exercise would prevent impairment of femoral artery FMD by limiting oxidative stress responses that increase endothelin-1 (ET-1) levels and disrupt nitric oxide (NO) status...

This article presents the case of a 53-year-old man who presented with acute right superficial femoral and popliteal arterial thrombosis for which he underwent an emergent uncomplicated thrombectomy. He denied preceding cardiovascular or neurologic symptomatology and had no history of coronary or peripheral arterial disease, trauma, hypercoagulability, or malignancy. However, he reported having several days of intense emotional stress prior to presentation. His cardiac exam was normal, his electrocardiogram showed normal sinus rhythm and nonspecific ST-T wave abnormalities, and his troponin levels were normal...
