Abstract
An endovascular approach is often considered the first line treatment option for lower limb chronic limb-threatening ischemia (CLTI), which is defined by the presence of ischemic rest pain and severe tissue loss, such as ulcers or gangrene. Although the technical success rate of endovascular revascularization is high, in specific patients with advanced infrapopliteal disease and the absence of run-off tibial vessels, the so-called 'desert foot', the chance of successful endovascular revascularization is minimal. In order to avoid primary amputation, several treatment options are currently being investigated, including gene therapy and deep venous arterialization. This review focuses on the percutaneous deep venous arterialization technique as a promising, minimally invasive treatment option for limb salvage in CLTI patients presenting with a 'desert foot'.
