The descending genicular artery as a recipient vessel in chronic limb-threatening ischemia - case report and literature review.

In recent decades, the increasing complexity of arterial bypasses in the management of chronic limb-threatening ischemia has spurred the development of alternative techniques, such as revascularization of genicular arteries. Few publications on this technique can be found in the literature, and its use has been restricted to specialized vascular groups. This article describes the case of a patient with extensive femorotibial occlusive disease who received a collateral artery bypass, using the deep femoral artery as a donor, the cephalic vein as an alternative autogenous substitute and the descending genicular artery as a recipient. Bypass to the descending genicular artery, although underutilized, is an effective option and increases the possibility of limb salvage in the management of chronic limb-threatening ischemia.
