A solution to ankle-brachial index limitations in peripheral transluminal angioplasty.

Purpose: We evaluated the limitations of the ankle-brachial index (ABI) in the revascularisation of diabetic patients with critical limb ischaemia (CLI) who were undergoing peripheral transluminal angioplasty (PTA) compared with the degree of arterial stenosis and with transcutaneous oxygen tension (TcpO2).

Materials And Methods: This prospective study assessed 250 consecutive diabetic patients in whom we evaluated results of posterior tibial and dorsalis pedis Doppler, ABI, TcpO2, and duplex scans. In total, 104 patients were considered suitable candidates for PTA.

Increased transcutaneous oxygen pressure is an indicator of revascularization after peripheral transluminal angioplasty.

Background: In recent years, the use of peripheral transluminal angioplasty (PTA) procedures for revascularization of an ischemic limb has increased. Evaluation of reperfusion has been carried out by Doppler scan; however, a successful PTA does not necessarily result in improved oxygen delivery to the distal parts of the limb.

Purpose: To evaluate the efficacy of the revascularization in diabetic patients with critical limb ischemia after treatment with PTA by comparing transcutaneous oxygen tension (TcpO₂) with the ankle-brachial index (ABI) post PTA.
