BACKGROUND: High failure rates of femoropopliteal artery (FPA) interventions are often attributed in part to severe mechanical deformations that occur with limb movement. Axial compression and bending of the FPA likely play significant roles in FPA disease development and reconstruction failure, but these deformations are poorly characterized. The goal of this study was to quantify axial compression and bending of human FPAs that are placed in positions commonly assumed during the normal course of daily activities...

BACKGROUND: Severe limb ischaemia (SLI) is defined as the presence of rest pain and/or tissue loss secondary to lower extremity atherosclerotic peripheral arterial disease. The superficial femoral and popliteal arteries are the most commonly diseased vessels in such patients and are being increasingly treated using endovascular revascularisation techniques. However, it is currently unknown whether drug-eluting stents and drug-coated balloons confer additional clinical benefits over more established techniques using plain balloons and bare metal stents, or whether they represent a cost-effective use of NHS resources...

OBJECTIVE: Preprocedural computed tomography angiography (CTA) assists in evaluating vascular morphology and disease distribution and in treatment planning for patients with lower extremity peripheral artery disease (PAD). The aim of the study was to determine the predictive value of radiographic findings on CTA and technical success of endovascular revascularization of occlusions in the superficial femoral artery-popliteal (SFA-pop) region. METHODS: Medical records and available imaging studies were reviewed for patients undergoing endovascular intervention for PAD between January 2013 and December 2015 at a single academic institution...

OBJECTIVE: In patients lacking autogenous vein suitable for infrainguinal bypass, cryopreserved saphenous vein (CSV) allograft (CryoLife, Inc, Kennesaw, Ga) may be an acceptable alternative. The purpose of this study was to examine outcomes of CSV conduit for infrainguinal revascularization. METHODS: Between February 2008 and August 2015, 70 patients underwent infrainguinal bypass grafts in 73 limbs using CSV. All patients lacked suitable arm or leg vein. Demographic data and patient outcomes were retrospectively collected using electronic medical records...

BACKGROUND: The role of collateral artery circulation in the lower limb is under debate but clinically relevant, particularly when using covered stents for occlusive disease. Covered stents seem to outperform nitinol stents in extensive disease, but collaterals could be essential in case of acute thrombosis. In the present study, we describe the collateral pathways of the deep and superficial femoral artery (DFA, SFA) and the popliteal artery (PA), observed in human cadavers. METHODS: Ten fresh frozen cadaver legs were selected...

Popliteal artery entrapment syndrome (PAES) is a rare cause of lower extremity arterial ischemia, especially in elder patients. At present, the role of the endovascular technique for PAES is still mainly auxiliary, there is no successful case treated successfully by endovascular treatment without open surgery, and also the long-term follow-up after endovascular treatment are lacking. We successfully treated a 51-year-old man with pale, cold right foot by endovascular therapy only, including percutaneous transluminal angioplasty and catheter directed thrombolysis...

We report a rare case of vascular graft-associated aneurysmal angiosarcoma by (18)F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). An 81-year-old male patient, with a prior history of graft interposition 1 year previously, was referred to (18)F-FDG-PET because of an inflammatory syndrome of unknown origin. FDG-PET images revealed a particular pattern of intense circular uptake within the arterial wall (SUVmax = 10) in a popliteal aneurysm and, additionally, a large hypermetabolic mass centered by the graft...

PURPOSE: Only anecdotal cases concerning primary stenting of thrombosed popliteal artery aneurysm (PAA) without a preoperative intra-arterial thrombolysis are reported. We report our series of six patients treated with this technique. CASE REPORT: Six male patients, aged between 63 and 88, came to our attention in the last 10 years for acute limb ischemia due to thrombosis of a PAA. In all the cases immediate digital subtraction angiography (DSA) was performed, the occlusion was crossed with an angiographic guidewire and, once an adequate distal landing zone was identified in the distal popliteal artery, a primary stenting was performed...

Adventitial cystic disease is a rare non-atheromatous cause of popliteal artery disease. Here, we present a case of a 51-year-old male patient who presented with right calf claudication caused by adventitial cystic disease. Preoperative magnetic resonance imaging and intraoperative findings revealed the presence of a connection between the cyst and adjacent knee joint. In addition, histopathological examination revealed that the tissue structure of the connection was similar to that of adventitial cysts. The tissue composed of two types of cells, namely macrophages and fibroblast-like cells, and lesional cells expressed D2-40...

A 55-year-old male with a history of iliac artery - popliteal artery polytetrafluoroethylene graft bypass presented 2 years later with sudden onset gross hematuria with sepsis. Computed tomography (CT) angiography was suggestive of fistula between ureter and iliac artery which was treated with arterial covered stent graft. The patient presented 2 weeks later with watery discharge from the previous scar. CT suggested ureter-cutaneous fistula. JJ stenting of ureter was done. The patient was discharged and on follow-up CT scan, there was no evidence of fistula and patient was completely asymptomatic...

OBJECTIVES: In cases of multilevel obstructive atherosclerotic disease, hybrid procedures of concomitant iliac artery stenting and femoro-popliteal bypass (IS-FPB) may represent a valid approach, but results are still unclear. The aim was to evaluate early and long-term outcomes of concurrent IS-FPB. METHODS: This retrospective study included 75 patients (76 limbs) treated with concomitant IS-FPB between January 2010 and June 2016. All patients were prospectively enrolled in a dedicated database...

BACKGROUND: The lack of early diagnosis, progression markers and effective pharmacological treatment has dramatic unfavourable effects on clinical outcomes in patients with peripheral artery disease (PAD). Addressing these issues will require dissecting the molecular mechanisms underlying this disease. We sought to characterize the Notch signaling and atherosclerosis relevant markers in lesions from femoral arteries of symptomatic PAD patients. METHODS: Plaque material from the common femoral, superficial femoral or popliteal arteries of 20 patients was removed by directional atherectomy...

Galectin-3 is a modulator of oxidative stress, inflammation, and fibrogenesis involved in the pathogenesis of vascular diseases. The present study sought to characterize, in patients with peripheral artery disease (PAD), the localization of galectin-3 in arterial tissue, and to analyze the relationships between the circulating levels of galectin-3 and oxidative stress and inflammation. It also sought to compare the diagnostic accuracy of galectin-3 with that of other biochemical markers of this disease. We analyzed femoral or popliteal arteries from 50 PAD patients, and four control arteries...

Peripheral artery disease (PAD) burdens a significant number of adult Americans and is associated with significant morbidity and mortality. The Transatlantic Inter-Society Consensus II (TASC II) guidelines standardize the degree of disease burden in individual vessel segments by assigning grades correlating to the complexity of lesion intervention. We sought data regarding endovascular approaches to lower extremity PAD in TASC C/D lesions in patients with claudication. Published data in these patients have demonstrated success in terms of procedural success, quality of life metrics, and intermediate to long-term primary patency rates...

Peripheral arterial disease (PAD) is a clinical manifestation of systemic atherosclerosis and is associated with significant morbidity and mortality. Vascular physicians come across PAD of different complexity and among them complex total occlusions present a formidable challenge to endovascular operators. Newer tools and techniques, particularly in the retrograde approach, have made endovascular therapy applicable to increasingly complex disease. In this article, we review various interventional devices and techniques that are key to achieving success in complex anatomic subsets...

True atherosclerotic aneurysms of superficial femoral artery (SFA) are rare and often associated with other peripheral or aortic aneurysms. We report the case of a 84-year-old patient presenting a giant degenerative ruptured aneurysm of the superficial femoral artery. The patient underwent successful aneurysm resection and bypass grafting, with a satisfying long-term follow-up and patency of the graft. The patient was also operated one year before, for a ruptured aneurysm of the abdominal aorta. This case report is rare, because we described a case of patient with multiple atherosclerotic aneurysms, who present, for the second time, a life threating ruptured aneurysm...

We report a case of traumatic anterior dislocation of the left knee in association with disruption of the soft tissues including knee ligaments, popliteal artery and common peroneal nerve, resulting in lower limb acute ischemia. All components of this complex trauma were recognised and treated promptly with rehabilitation commencing early. The present case is important in two aspects: firstly it reports a very rare occurrence of simultaneous anterior dislocation of the knee associated with vascular insult and common peroneal nerve injury, that was rarely reported in the current literature; secondly it highlights that with timely intervention and a team approach excellent results could be achieved...

BACKGROUND: Shortwave diathermy (SWD) and microwave diathermy (MWD) are frequently used by physical therapists to treat musculoskeletal conditions. The therapeutic benefits are usually associated with an increase in tissue temperature; however, there is no consensus on the changes in blood flow. OBJECTIVES: 1) To evaluate the behavior of temperature and arterial blood flow after the application of SWD and MWD to the lower limb of healthy women aged 18-30 and 2) to assess whether changes in limb positioning can influence SWD response...
