Superficial femoral artery stent

Sorin Giusca, Tom Eisele, Dorothea Raupp, Christoph Eisenbach, Grigorios Korosoglou
Currently, the treatment of thromboembolic ischemia of the lower extremities includes percutaneous rotational thrombectomy and aspiration devices. However, the standard approach for endovascular treatment requires the administration of iodine contrast agents, which is problematic in patients with pre-existing renal disease and diabetes. Herein, we describe a case of a CO2 angiography guided endovascular thrombectomy of the superficial femoral artery (SFA) in a young patient with critical limb ischemia. Mechanical thrombectomy using the Rotarex system, catheter aided aspiration and subsequent stent placement in the SFA was entirely guided using CO2 angiography...

OBJECTIVES: The aim of this study was to investigate the efficacy and safety of a new paclitaxel-coated balloon catheter in the treatment of stenotic or occluded femoropopliteal arteries. BACKGROUND: The incidence of restenosis can be reduced by the use of drug-coated balloons. However, dose, coating composition, and technology are decisive for efficacy. METHODS: Two hundred Chinese patients with peripheral arterial occlusive disease were prospectively randomized to treatment with new paclitaxel-coated or standard uncoated balloon catheters...

PURPOSE: To quantify the deformation behavior of the diseased femoropopliteal segment and assess the change to deformation behavior due to various stent placements. METHODS: The length and curvature changes of 6 femoropopliteal segments (the right and left superficial femoral and popliteal arteries) from 3 cadavers were measured in 3-dimensional space based on rotational angiography image data in straight leg and flexed hip/knee (50°/90°) positions before and after placement of nitinol stents of varying type (EverFlex, Misago, and BioMimics 3D) and length (60, 100, and 200 mm) in different locations along the arteries...

Endovascular techniques have improved markedly over the past several decades. Plain old balloon angioplasty can only reach patencies around 40% after 1 year. Scaffolding stents have resulted in improved short-term results but encountered limitations for longer-term durability. With the introduction of drug-eluting technologies the process of intimal hyperplasia might be slowed, resulting in improved long-term patency results. At first, limus-eluting technologies were not able to transfer the enthusiasm from the coronaries to the infrainguinal vascular bed...

PURPOSE: To evaluate the clinical efficacy of poststenting fractional flow reserve (FFR) in terms of predicting restenosis in superficial femoral artery (SFA) disease. METHODS: This prospective, single-center, nonrandomized study enrolled 48 patients (mean age 76±9 years; 38 men) with 51 SFA lesions from July 2013 to June 2014. Mean FFR (distal mean pressure/proximal mean pressure) and systolic FFR (distal systolic pressure/proximal systolic pressure) were calculated, and the relationship between these FFR values and restenosis at 12 months was investigated using receiver operating characteristic (ROC) curve analysis...

May-Thurner syndrome is the condition of the left common iliac vein being compressed between the right common iliac artery and the associated vertebral body. This condition has been linked to spontaneous episodes of deep vein thrombosis (DVT), especially in women aged 20-50, and it may contribute to the slightly higher tendency to develop left-sided (~56%) versus right-sided DVTs. A 50-year-old morbidly obese (BMI 42.7 kg/m(2)) female presented to the emergency room with acute left leg pain. Past medical history included asthma...

PURPOSE: To report preliminary experience with femoropopliteal revascularization using a completely transpedal/transtibial approach. MATERIALS AND METHODS: Three patients with Rutherford 3-4 disease underwent revascularization of TASC C/D lesions using a pedal/tibial artery as the only site of arterial access. RESULTS: One patient with a chronic superficial femoral artery occlusion had continuity achieved to the common femoral artery using a dedicated reentry device and stenting; in a second patient, an occluded popliteal artery stent was successfully revised with an endograft; and in a third patient with morbid obesity, a chronic SFA occlusion was successfully stented...

Peripheral vascular disease (PVD) is a devastating medical problem that may lead to significant life alterations for patients, from simply limiting their daily activities to potential loss of limbs and eventual demise. Superficial femoral and popliteal arteries are significantly common locations for PVD sequelae to present itself, and owing to their length and mobile nature, treatment of these segments are quite challenging. Indications for PVD treatment include lifestyle-limiting claudication that is not responding to medical management, ischemic rest pain, nonhealing ulcers, and lower extremity gangrene...

OBJECTIVES: The hypothesis that paclitaxel-eluting balloon angioplasty provides higher 1-year patency rates in femoropopliteal artery in-stent restenosis compared with standard percutaneous transluminal angioplasty (PTA) was tested. BACKGROUND: Several trials have demonstrated that paclitaxel-eluting balloon angioplasty reduces late luminal loss in comparison with PTA. METHOD: In a prospective, randomized, single-blind, dual-center study, 74 patients with symptomatic peripheral artery disease due to in-stent restenosis were treated with either paclitaxel-based drug-eluting balloon (DEB) angioplasty (n = 35) or standard PTA (n = 39)...

INTRODUCTION: Limb occlusion after endovascular aneurysm repair (EVAR) is a well-known complication. However, extensive ischemic ulcers due to limb occlusion are extremely rare. CASE DESCRIPTION: We report a rare case of extensive ischemic ulcers that developed seven months after EVAR in an 85-year-old Japanese man. He had been taking appropriate anticoagulant therapy because of paroxysmal atrial fibrillation. Angiography showed a left limb occlusion and superficial femoral artery (SFA) chronic total occlusion (CTO), and intravascular ultrasound showed limb kinking...

PURPOSE: A novel approach for arterial bypass grafting using exclusively endovascular techniques was established in-vitro in a phantom model. MATERIAL AND METHODS: The experimental setting consisted of a gel-wax phantom with two embedded parallel fluid-filled silicon tubes simulating the superficial femoral vessels. Through an 8-French sheath, a re-entry catheter (OUTBACK(®), Cordis) was placed in the simulated artery and used to puncture the vascular wall. Then a 0...

INTRODUCTION: Percutaneous endovascular revascularization requires the use of fluoroscopic guidance and radiopaque contrast. We present a successful intervention without the use of iodinated contrast. CASE: A 92-year-old man with dry gangrene involving the second and fourth left toes had acute on chronic kidney injury. Arterial duplex showed severe stenosis in bilateral superficial femoral arteries (SFAs). Fluoroscopic and ultrasound guidance and intravascular imaging were used to avoid iodinated contrast...
