We describe a case of an infected popliteal artery stent with septic emboli presenting 6 years after peripheral vascular intervention for intermittent claudication. Management included resection of the stent and popliteal artery and revascularization by femoral-popliteal bypass with autogenous vein. This case demonstrates that peripheral stent infections can develop years after intervention. We performed an English language PUBMED literature review of arterial peripheral vascular stent infections on using the search term, "Non-coronary stent or stent graft infection from 1966 to present...

Restenosis caused by neointimal hyperplasia significantly decreases long-term efficacy of percutaneous transluminal angioplasty (PTA), stenting, and by-pass surgery for managing coronary and peripheral arterial diseases. A major cause of pathological neointima formation is abnormal vascular smooth muscle cell (VSMC) proliferation and migration. Notoginsenoside R1 (NGR1) is a novel saponin that is derived from Panax notoginseng and has reported cardioprotective, neuroprotective and anti-inflammatory effects...

AIM: In-Stent Restenosis (ISR) is the major reason for recurrent ischemia and amputation after endovascular treatment of Peripheral Artery Disease (PAD). Our previous study demonstrated that miR-140-3p is significantly down-regulated in PAD arteries. However, expression and function of miR-140-3p in ISR of human PAD are currently unclear. The aim of this study is to determine the miR-140-3p expression and its regulative role in ISR of PAD. METHODS: The RNA level was determined by quantitative real-time polymerase chain Reaction (qRT-PCR) and in situ hybridization...

The femoropopliteal artery is one of the commonest sites of involvement in peripheral artery disease (PAD) leading to intermittent claudication and/or critical limb ischemia. Endovascular therapy for superficial femoral artery (SFA) disease has been recognized as a safe and efficient therapy and is recommended by current guidelines as the first-line approach. Although the widespread use of new-generation, self-expanding, nitinol stents in SFA stenosis has reduced the shortcomings associated with plain old balloon angioplasty (POBA), lumen renarrowing at the stented (in-stent restenosis - ISR) level still represents a relevant clinical problem, because of higher risk of recurrent ISR, occlusion and surgical revascularization compared to de-novo lesions...

Degenerative femoral artery aneurysms are uncommon and often associated with aneurysm in other distributions. We report a case of a 68-year-old man with multianeurysmal disease involving the aorta, iliac, femoral, and popliteal arteries managed interdisciplinary by stent-graft placement and open surgical repair. Genetic testing revealed a variant in the FBN2 gene encoding fibrillin-2, an important component of microfibrils. We detail arterial reconstruction of the femoral artery and discuss incidence, diagnosis, and therapy of femoral artery aneurysms...

OBJECTIVES: This study was designed to evaluate outcomes of adventitial dexamethasone delivery adjunctive to standard endovascular revascularization in femoropopliteal peripheral artery disease. BACKGROUND: Drug-coated balloons and drug-eluting stents improve patency of endovascular interventions with passive diffusion of antiproliferative drugs. Adventitial dexamethasone delivery targets the initial triggers of the inflammatory reaction to injury, thus potentially providing a potent antirestenotic strategy...

Mechanical insults, such as stent implantation, can induce endothelial injury, vascular inflammation, and ultimately lead to vascular neointimal hyperplasia. Resolvin E1 (RvE1), derived from the ω3 fatty acid eicosapentaenoic acid, can facilitate the resolution of inflammation in many settings. We therefore aimed to determine if there was a role for RvE1 in preventing neointimal formation after arterial injury and to understand the underlying mechanisms. Vascular inflammation and neointimal hyperplasia were induced by wire injury in the femoral arteries of mice...

Occlusive arterial disease, including coronary heart disease (CHD) and peripheral arterial disease (PAD), is the main cause of death, with an annual mortality incidence predicted to rise to 23.3 million worldwide by 2030. Current revascularization techniques consist of angioplasty, placement of a stent, or surgical bypass grafting. Autologous vessels, such as the saphenous vein and internal thoracic artery, represent the gold standard grafts for small-diameter vessels. However, they require invasive harvesting and are often unavailable...

Iatrogenic iliac vein dissection secondary to femoral artery puncture is a rare complication that has not yet been documented. A 55-year-old woman presented to our institution with acute right iliofemoral thrombosis 2 weeks after transfemoral cerebral angiography. She was previously healthy and was not taking any medication. Right iliofemoral vein dissection was diagnosed by computed tomography angiography and confirmed by conventional venography. The patient was treated endovascularly with stent insertion, and the venous outflow was patent on the 6-month follow-up computed tomography angiogram...

Asymptomatic double aortic arches are a unique occurrence. An incidental finding of a double aortic arch in an elderly male was discovered during work up of a transient ischemic attack. The following case presentation details an effective treatment approach in cerebrovascular stenting in a patient with variant aortic arch anatomy. The initial diagnostic cerebral angiogram was performed via trans-femoral approach and was quite challenging. Faced with challenging anatomy, the radial artery approach is a viable option when navigating into the cerebrovascular anatomy for stenting when proximal variants such as a double aortic arch are identified...

INTRODUCTION: Phlegmasia cerulea dolens (PCD) is a rare complication of deep venous thrombosis (DVT). Massive ileo-femoral DVT is usually the cause and prompt treatment is mandatory as it represents a medical emergency. Reported amputation rates range from 12% to 25% and mortality ranges from 25% to 40%. Limb ischemia results from obstruction to arterial inflow secondary to extreme levels of venous hypertension. Primary treatment goal is restoration of venous outflow and can be achieved by endovascular or surgical techniques...

Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®). METHODS: We describe the case of a 70-year-old patient who was admitted to the emergency room due continuous low back pain with 3 days of evolution...

The article reflects the experience in and efficacy of endovascular interventions in patients presenting with type C and D lesions of the superficial femoral artery (SFA) according to the TASC II classification. The study included a total of 89 patients with the pathology involved. The obtained findings demonstrated encouraging immediate and remote results of the interventions performed, thus making it possible to recommend the use of angioplasty and stenting of long occlusions of the SFA, yielding satisfactory results in the majority of cases, both immediately after the operation and in the remote period...

Treatment of thoracic aortic rupture poses a substantial challenge for the aortic surgeon. The advent of thoracic endovascular aortic repair (TEVAR) revolutionized the treatment of this heterogeneous group of diseases. However, some patients suitable for TEVAR present severe peripheral vascular diseases which can prevent standard retrograde delivery of the stent-graft through the femoral artery. In this article, we present a case series of five patients with thoracic aortic rupture successfully treated with cardiac trans-apical TEVAR...

In this seminar, I would like to discuss the recent hybrid operations in patients with peripheral arterial diseases. Hybrid is generally defined as combinations of different types of things. In the surgical community, it is loosely defined as therapy combining open surgery (OS) and endovascular therapy (EVT). In practice, combination surgery of diseased inflow vessels by EVT and outflow vessels by OS is a typical example, namely, the combination therapy of thromboendarterectomy (TEA) for common femoral artery and EVT (PTA and stenting) for iliac artery in patients with PAD (ilio-femoral lesions)...

PURPOSE: To avoid distal plaques embolization during carotid artery stenting, we developed Universal Protection Method that combined the use of a proximal common carotid artery balloon, an external carotid artery balloon, and a distal internal carotid artery filter, with continuous flow reversal to the femoral vein. Herein, we assessed the efficacy of the Universal Protection Method by comparing stenting outcomes before and after its introduction. MATERIALS AND METHODS: We assessed outcomes for 115 cases before and 41 cases after the Universal Protection Method was adopted (non-Universal Protection Method and Universal Protection Method groups, respectively)...

Background: Endovascular stenting has surpassed bypass surgery to become the first-line treatment for superficial femoral artery (SFA) occlusive disease, and various types of stents including bare-metal stents (BMSs), covered stents, and drug-eluting stents (DESs), have been approved for treatment. This retrospective, single-institute study compared the short-term, real-world outcomes of BMSs and DESs for treating SFA occlusive disease. Methods: A retrospective chart review was used to enroll 94 patients who received a DES (n = 24) or BMS (n = 70) between 2009 and 2014...

BACKGROUND: Patients' intra and post procedural comfort, quick recovery, as well as procedure success, are key elements for choosing the right arterial access site. Radial artery access has been of increasing interest since it was first described. Advanced treatments of coronary lesions, from primary percutaneous interventions during ST elevation myocardial infarction cases to chronic total occlusion cases, have been increasingly done through the radial access. Distal left trans radial artery (dlTRA) is a new technique first described by Kiemineij...

MYOCARDIAL INFARCTION IN THE OLD PATIENT: Even old patients may crucially benefit from reopening the occluded coronary artery by percutaneous coronary intervention with stent implantation. Bleeding complications can be reduced by choosing the radial instead of the femoral vascular approach for cardiac catheterization. STATINS FOR THE ELDERLY: WHEN TO START UND WHEN TO STOP?: Elderly benefit no less than the younger from statins. "Goal-oriented statin therapy" is preferable to the "statin strategy of fixed dose"...
