Runoff Detected by Magnetic Resonance Angiography as an Indicator for Better Recanalization Outcomes in Below-the-Knee Chronic Total Occlusions in Diabetic Patients

Abstract

Distal runoff detected using MRA could be a predictor for successful intraluminal recanalization, better distal tissue perfusion, improved long-term patency, and better limb salvage for patients with BTK CTOs.

Abdominal Aortic Hemodynamics in Intermittent Claudication Patients at Rest and during Dynamic Pedaling Exercise

“…Clinically, blood flow rate has been shown to be a strong predictor of patency following angioplasty, bypass, or arteriovenous fistula [12–14]. And for disease research, blood flow, among other hemodynamic conditions, is necessary to understand the mechanisms of atherosclerosis development.…”

Magnetic resonance imaging characteristics of lesions relate to the difficulty of peripheral arterial endovascular procedures

“…CTA with runoff is nondiagnostic in 17% to 52% of infrapopliteal studies, 4 yet runoff is a recognized predictor of endovascular success. 5,6 Duplex ultrasound can visualize some features of the vessel wall and provides physiologic flow information, but it suffers from calcium acoustic shadowing, variable quality, user dependence, and limited field of views for procedure planning. Many physicians do not feel confident in making therapeutic decisions on the basis of ultrasound alone 7 and often order additional investigations.…”

Commentary: Intra-arterial Digital Subtraction Angiography

“…In the current issue of the JEVT , Zhu et al 1 compared the feasibility and efficacy of recanalizing tibial artery chronic total occlusions (CTOs) between patients with good or poor distal runoff based on magnetic resonance angiography (MRA) scans. They found that distal runoff detected using MRA could be a predictor for successful intraluminal recanalization, better distal tissue perfusion, improved long-term patency, and better limb salvage for patients with CTOs of the tibial arteries.…”
