Anterograde or retrograde arterial access for diabetic limb revascularization.

The selection of an optimal vascular access strategy for lower limb endovascular intervention is key for procedural safety and success, and is particularly relevant in diabetic patients, in whom extensive occlusive disease commonly involves the infrapopliteal arteries. Individualizing vascular access requires careful planning, including determining normal and abnormal arterial anatomy; the patient's co-medical conditions, especially renal insufficiency; and review of noninvasive vascular laboratory testing. It is essential to be cognizant of the technical nuances, relative safety, advantages, and disadvantages of each potential access site. Retrograde and antegrade femoral approaches; upper extremity access via the radial, brachial, or axillary arteries; or retrograde access via the below-the-knee popliteal or pedal arteries should all be considered in endovascular intervention planning.
