“…When using cryoplasty catheters, reduced postinterventional neointima formation is expected due to the supplementary application of cold. As a result, lower dissection rates with similar long-term patency compared to conventional PTA in the case of arterial stenoses of the femoropopliteal circulation were described [68]. In a case series of only five patients with dialysis grafts, the superiority of cryoplasty compared to conventional PTA could be shown in the case of pronounced recurrent stenoses of the venous anastomosis [16].…”

A wide variety of diagnostic and minimally invasive modalities is currently available to radiologists for providing sufficient medical care for dialysis patients. In addition to clinical examination, ultrasound is the first line imaging method in suspected dialysis vascular access dysfunction. The percutaneous approach is the primarily recommended therapeutic option in many cases. This article reviews the current diagnostic and therapeutic methods in dialysis vascular access insufficiency. Key Points: ??Vascular access dysfunction is often elicited by stenosed vessels, which are regularly associated with concomitant thrombosis. ??Stenoses are commonly observed in the anastomosis, vascular access vein and also in the central venous system. ??Beside the clinical examination, sonography is the diagnostic method of first choice. ??Percutaneous balloon dilatation frequently is the first treatment option.

“…32 Clinical data show that outcomes following cryoplasty in claudicants are no better than the results that may be expected with conventional balloon angioplasty. 33,34 There is little data supporting the use of cryoplasty in CLI at present. The results of the Below the Knee (BTK) Chill study, in which 100 patients with CLI were treated with belowknee cryoplasty, have yet to be published.…”

Endovascular therapy for critical limb ischemia

Chronic critical limb ischemia (CLI) occurs when arterial perfusion is reduced below a threshold level that results in rest pain and/or tissue breakdown in the lower extremities. Importantly, it is associated with high cardiovascular morbidity and mortality. Without prompt revascularization, CLI may result in loss of a limb (i.e. amputation) and/or life. The goal of endovascular therapy is the re-establishment of pulsatile, straight-line flow to the distal extremity. Percutaneous transluminal angioplasty (PTA) has been shown to be effective and safe in the setting of CLI, with limb salvage rates that compare favorably with surgical procedures. Stents are indicated for failed PTA, while adjunctive therapies such as lasers, thermal angioplasty and atherectomy devices lack data demonstrating improved efficacy compared with conventional lower extremity interventions. In addition to successful revascularization, the institution of lifestyle changes, atherosclerotic risk factor modification, and pharmacologic therapies are indicated to reduce cardiovascular morbidity and mortality.

“…Primary assisted and secondary patency rates were 94% and 98%, respectively. 11 Extended follow-up data on 70 patients from the multicenter registry at Ͼ3 years (1253 days) from the procedure demonstrated that the clinical patency rate was well maintained at 75%. 12 An additional prospective, multicenter registry of cryoplasty for infrapopliteal lesions in patients with critical limb ischemia has been completed.…”

Overview of New Technologies for Lower Extremity Revascularization

Abstract-Lower extremity peripheral arterial occlusive disease poses a unique challenge to traditional angioplasty-based endovascular therapies. The diffuse nature of lower extremity atherosclerotic disease, the presence of chronic total occlusions, poor distal runoff, and the presence of critical limb ischemia all have contributed to the disappointing results of balloon angioplasty for complex infrainguinal arterial disease. These challenges have spawned the development of a host of new technologies in an attempt to improve the safety and effectiveness of percutaneous revascularization for lower extremity peripheral arterial occlusive disease. This review summarizes the recent advances in available technologies, including novel angioplasty balloons; nitinol stents, stent grafts, and drug-eluting stents; excisional, laser, and rotational atherectomy devices; devices for crossing total occlusions; true-lumen reentry devices; thrombectomy catheters; and embolic protection devices.
