High failure rates of femoropopliteal artery (FPA) interventions are often attributed to severe mechanical deformations that occur with limb movement. Torsion of the FPA likely plays a significant role, but is poorly characterized and the associated intramural stresses are currently unknown. FPA torsion in the walking, sitting and gardening postures was characterized in n = 28 in situ FPAs using intra-arterial markers. Principal mechanical stresses and strains were quantified in the superficial femoral artery (SFA), adductor hiatus segment (AH) and the popliteal artery (PA) using analytical modelling...

We present the case of a patient with a history of aortobifemoral grafting who presented with left lower extremity ischemic rest pain. Aortofemoral angiography was performed through a left radial access and showed a long, calcified total occlusion of the left superficial femoral artery (SFA) and a subtotal popliteal occlusion. The popliteal artery and SFA were crossed retrogradely through a 4-Fr anterior tibial access; the retrograde devices went subintimally and did not reenter at the common femoral level...

INTRODUCTION: Vascular homografts are used for limb salvage in cases of graft infection after previous reconstructive vascular surgery or inadequate autologous veins. During multi-organ donation the thoracic aorta segment, aortic bifurcation, iliac arteries, femoral arteries, popliteal arteries, femoral veins and greater saphenous veins can be harvested. Our aim was to optimize the use of homografts by analyzing the results of previous procedures. METHODS: The patient information was processed retrospectively, using the clinical computer system...

This case describes the surgical repair of profunda femoris artery aneurysm in a patient with a history of metasynchronous superficial femoral artery aneurysm. It demonstrates the value of screening for arterial aneurysms in patients presenting with isolated peripheral arterial aneurysms. We detail open surgical approach of aneurysm resection and subsequent revascularization with interposition graft. We also review the literature for this condition and discuss other approaches to this rare finding. The patient in this case report has consented to publication of this manuscript...

Persistent sciatic artery is a rare developmental anomaly prone to atherosclerotic disease. We present a case of successful endovascular therapy for left persistent sciatic artery that was occluded at the distal site. The angioplasty was performed with both antegrade approach from contralateral common femoral artery and retrograde approach from ipsilateral superficial femoral artery. The guidewire was advanced via collateral channel and crossed through the lesion retrogradely. Rendez-vous technique was performed and the lesion was successfully dilated by balloon inflation...

OBJECTIVE: Inflammation as a significant influence factor plays an important role in the formation and rupture of intracranial aneurysms. However, based on plenty of related studies, it is believed that the hepatocyte growth factor (HGF) is able to prevent vascular inflammation. This paper, therefore, explored the role and mechanism of endogenous HGF in the pathogenesis of intracranial aneurysms. MATERIALS AND METHODS: 16 blood samples were collected from the intracranial aneurysms and the lumens of the femoral artery of 16 patients...

BACKGROUND: Surgical revascularization for chronic critical limb ischaemia in patients with thromboangiitis obliterans (TAO) still remains controversial. Generally, besides cessation of smoking, conservative treatment supported by intravenous administration of vasoactive agents is regarded as the treatment of choice, in combination with local wound therapy or minor amputation. PATIENTS AND METHODS: In four male patients (42-47 years) surgical revascularization was chosen as therapy for established gangrene or non-healing ulceration after unsuccessful conservative treatment and cessation of smoking...

Carotid - femoral pulse wave velocity is an established measure to assess cardiovascular risk and an interesting surrogate parameter towards non-invasive continuous blood pressure inference. Due to progress in sensing technologies for wearable wrist worn sensors, there are low cost sensor combinations of photo-plethysmography and high fidelity accelerometers available offering access to pulse information from larger arteries complemented by blood volume changes in the superficial tissue. In this work we compare pulse wave velocities derived from accelerometer and reflective photo-plethysmography signals placed at the carotid and femoral artery...

REVIEW
Ashwin Nathan, Taisei Kobayashi, Jay Giri
The superficial femoral artery is a complex artery subject to a unique set of biomechanical loading conditions in its course through the leg. Plain balloon angioplasty and balloon-expandable stents had unacceptably high rates of restenosis, necessitating target vessel revascularization. Nitinol alloy is well suited to provide the strength and flexibility needed of stents to withstand the external forces posed by the environment of the superficial femoral artery. Advances in stent technology with the addition of a slow-releasing antiproliferative agent and changes in scaffold design have shown promise in reducing the rates of stent fracture and in-stent restenosis...

BACKGROUND: Chronic total occlusions (CTOs) are challenging to treat endovascularly. Classic subintimal approach is offering only moderate success rates mainly due of the lack of dedicated crossing catheters. Purpose of this study is to assess the acute procedural success of the use of a novel hydrophilic crossing catheter in the recanalization of peripheral CTOs. MATERIALS AND METHODS: This is a retrospective, single-centre study of patients with femoropopliteal CTOs...

BACKGROUND: The optimal sizing of self-expanding paclitaxel-eluting stents (PES) in the treatment for superficial femoral artery (SFA) lesions is unclear. This study sought to investigate the influence of PES diameter on stent patency in SFA lesions using optical frequency domain imaging (OFDI). METHODS: A total of 20 de novo SFA lesions were randomized 1:1 to receive either self-expanding PES with a nominal diameter of 6mm or 8mm. Follow-up angiography and OFDI was scheduled six months after stent implantation, and volumetric OFDI analysis was performed to evaluate vascular response to the stents...

REVIEW
Yoshiaki Yokoi
Most cases of femoral-popliteal disease require aggressive medical treatment, but patients with severe lifestyle-limiting symptoms and limb-threatening disease are increasingly receiving endovascular treatment. The femoropopliteal artery is the longest vessel in the thigh and the unique physical forces involved in this vessel are considered to cause high rates of restenosis and stent fracture. Endovascular therapy for superficial artery (SFA) disease is still a challenge in terms of long-term patency and clinical effectiveness...

Atherosclerosis is a systemic disease with different faces. Despite similar, or even identical, risk factors and pathogenesis, atherosclerotic lesions and their clinical manifestations vary in different parts of the vasculature. Peripheral arterial disease (PAD) in the superficial femoral artery (SFA) represents a frequent clinical manifestations of atherosclerotic disease. The pathohistological characteristics of plaques in PAD differ from lesions in the coronary arteries. Plaques in the SFA have more fibrotic elements with less lipid and degenerative tissue elements; this makes them more stable and less prone to rupture...

Pseudoaneurysm is a relatively common complication of arterial injury. Arterial pseudoaneurysms have many different etiologies, including trauma, iatrogenic injury, vascular repair, infection, and vasculitides. In this case report, we present a pseudoaneurysm created by a fracture of superficial femoral artery stent secondary to a mechanical fall. To our knowledge, this is the first report of a symptomatic pseudoaneurysm caused by a superficial femoral artery stent fracture. The large, unruptured pseudoaneurysm in this case was successfully treated with a covered stent and pseudoaneurysm exclusion...
