OBJECTIVE: In recent years, a controversial discussion about the clinical relevance of the angiosome concept during tibial angioplasty has developed. Therefore, we conducted a prospective study to evaluate the angiosome concept on the level of microcirculation during tibial vascular interventions. METHODS: Thirty patients with isolated tibial angioplasty were examined prospectively. Macrocirculation was evaluated by measurement of the ankle-brachial index (ABI)...

BACKGROUND: Drug-eluting balloon (DEB) and standard percutaneous transluminal angioplasty (PTA) are commonly used endovascular therapeutic procedures for the revascularization of infrapopliteal arterial occlusive disease. However, which procedure is more beneficial for patients is unknown. METHODS AND RESULTS: We performed a meta-analysis, searching PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, ISI Web of Knowledge, and relevant websites without language or publication date restrictions for randomized trials that compared DEB with PTA in patients with infrapopliteal arterial occlusive disease...

Analysed herein are both immediate and remote results of surgical treatment of 93 patients presenting with chronic atherosclerotic occlusion of the femoral-popliteal-tibial segment in the stage of critical ischaemia. The patients were subjected to autovenous femoropopliteal bypass grafting to the isolated arterial segment or balloon angioplasty with stenting of the superficial femoral artery. While choosing the method of arterial reconstruction we assessed concomitant diseases, primarily lesions of the coronary and cerebral circulation...

OBJECTIVES: The aim of this study was to investigate the midterm performance of an everolimus-eluting, bioresorbable vascular scaffold (Absorb, Abbott Vascular, Santa Clara, California) for the treatment of focal tibial and distal popliteal lesions. BACKGROUND: Drug-eluting stents are used below the knee to improve technical success and durability, but the ongoing presence of a permanent metal scaffold may have deleterious effects on the local vessel. METHODS: Tibial and distal popliteal angioplasty with scaffold placement was performed using an everolimus-eluting, bioresorbable scaffold (Absorb)...

BACKGROUND: Atherosclerotic peripheral arterial disease (PAD) can lead to disabling ischemia and limb loss. Treatment modalities have included risk factor optimization through life-style modifications and medications, or operative approaches using both open and minimally invasive techniques, such as balloon angioplasty. Drug-eluting balloon (DEB) angioplasty has emerged as a promising alternative to uncoated balloon angioplasty for the treatment of this difficult disease process. By ballooning and coating the inside of atherosclerotic vessels with cytotoxic agents, such as paclitaxel, cellular mechanisms responsible for atherosclerosis and neointimal hyperplasia are inhibited and its devastating complications are prevented or postponed...

In order to assess the role of drug-coated balloons (DCB) in below-the-knee (BTK) artery interventions, we analyzed randomized trials which compare coated to non-coated balloons and additionally a direct comparison of drug-eluting stents (DES) with DCB. As angioplasty with non-coated balloons is per guideline-recommendation still standard of care for below-the-knee artery endovascular treatment, we focused on the direct comparison of efficacy and clinical outcome data of both treatment modalities. Data from peer reviewed and published trials were consulted...

OBJECTIVE: Tibial artery calcification (TAC) is associated with increased risk of amputation and mortality in peripheral artery disease. We sought to investigate whether the severity of TAC based on semiquantitative analysis of computed tomography angiography (CTA) can predict outcomes of endovascular therapy in patients with critical limb ischemia. METHODS: We reviewed medical records of 124 patients who underwent lower extremity CTA before intervention. Based on CTA, TAC severity was categorized into three groups: minimal calcification (MC; n = 43), intermediate calcification (IC; n = 36), or extensive calcification (EC; n = 45)...

OBJECTIVES: Endofibrosis is a rare clinical entity that usually manifests as claudication in cyclists and other endurance athletes. We report a case of a 43-year-old cyclist presenting with pain and cyanosis of his toes due to an embolism to his left anterior tibial artery. The source of the embolism was found to be an ulcerated, endofibrotic plaque in his left common femoral artery. METHODS: We performed an extensive literature search using the Pubmed database and identified 60 results on endofibrosis...

We here report a successful angioplasty for tibial artery occlusion using direct tibial puncture and subsequent retrograde approach under surgical cutdown technique. An 82-year-old man with ulcer/gangrene in first and second digits was referred to our hospital for endovascular therapy (EVT) of lower extremity ischemia. Diagnostic angiogram revealed anterior tibial artery (ATA) occlusion with severe calcification. Subintimal angioplasty was attempted using a 0.014-inch hydrophilic guidewire but was unsuccessful...

RATIONALE: Restenosis due to intimal hyperplasia (IH) is a major clinical issue that affects the success of lower limb endovascular surgery. After 1 year, restenosis occurs in 40% to 60% of the treated vessels. The possibility to reduce IH using local antiproliferative drugs, such as taxols, has been the rationale for the clinical applications of drug-eluting stents and drug-eluting balloons (DEBs). The purpose of this study was to evaluate the clinical and instrumental efficacy of DEBs versus simple percutaneous transluminal angioplasty (PTA) in patients affected by chronic limb ischemia (CLI) with tibial artery "de novo" lesions...

PURPOSE: To describe the combined use of radial-pedal access for recanalization of complex superficial femoral artery (SFA) occlusions unsuitable for transfemoral recanalization. TECHNIQUE: Patients are selected for this strategy if they have a long (≥ 10 cm) SFA occlusion with unfavorable aortoiliac anatomy, an absent ostial stump, or severely diseased and calcified distal reconstitution. Left radial artery and distal anterior or posterior tibial artery are accessed with 6-F and 4-F sheaths, respectively...

BACKGROUND: Severe limb ischaemia is defined by ischaemic rest/night pain, tissue loss, or both, secondary to arterial insufficiency and is increasingly caused by infra-popliteal (below the knee) disease, mainly as a result of the increasing worldwide prevalence of diabetes. Currently, it is unknown whether vein bypass surgery or the best endovascular treatment (angioplasty or stenting) represents the optimal revascularisation strategy in terms of amputation-free survival, overall survival, relief of symptoms, quality of life and cost-effective use of health care resources...

BACKGROUND: Endovascular revascularization is an established approach for limb salvage in the setting of critical limb ischemia. However, failure rate of antegrade recanalization in complex femoropopliteal to infrapopliteal occlusions is as high as 20%. We report a series of 21 patients who underwent retrograde pedal access and recanalization of below-the-knee chronic total occlusions after failed antegrade attempts. METHODS: This is a retrospective review of prospectively maintained data for all patients who underwent ultrasound-guided percutaneous pedal access for retrograde endovascular treatment of advanced tibial vessel disease between 2011 and 2014...
