Competing Risk Analysis of the Impact of Pedal Arch Status and Angiosome-Targeted Revascularization in Chronic Limb-Threatening Ischemia.

Background: In the context of chronic limb-threatening ischemia, the prognostic impact of angiosome-targeted revascularization and of the status of the pedal arch are debated.

Methods: This series includes 580 patients who underwent endovascular (n = 407) and surgical revascularization (n = 173) of the infrapopliteal arteries for chronic limb-threatening ischemia associated with foot ulcer or gangrene. The risk of major amputation after infrapopliteal revascularization was assessed by a competing risk approach.

Quality Control of the Foot Revascularization Using Indocyanine Green Fluorescence Imaging.

Objectives: Critical limb ischemia (CLI) is a clinical diagnosis, confirmed by objective tests, usually ankle-brachial index (ABI), toe pressure (TP) and TcPO2. Furthermore, the anatomical lesions in patients affected by CLI were visualized by ultrasound, angiography, CTA, or MRA. Indocyanine green fluorescence imaging (ICG-FI) is a diagnostic modality for assessing foot perfusion.

Angiosome Targeted PTA is More Important in Endovascular Revascularisation than in Surgical Revascularisation: Analysis of 545 Patients with Ischaemic Tissue Lesions.

Introduction: This study aimed to evaluate the impact of angiosome targeted (direct) revascularisation according to revascularisation method in patients with diabetes.

Materials And Methods: This retrospective study cohort comprised 545 diabetic patients with critical limb ischaemia and tissue loss (Rutherford 5, 6). All patients underwent infrapopliteal endovascular (PTA) or open surgical revascularisation between January 2008 and December 2013.

The Prognostic Significance of Different Definitions for Angiosome-Targeted Lower Limb Revascularization.

Background: The definition of angiosome-targeted revascularization is confusing, especially when a tissue lesion affects several angiosomes. Two different definitions of direct revascularization exist in the literature. The study aim was (1) to compare the 2 definitions of direct revascularization in patients with foot lesions involving more than one angiosome and (2) to evaluate which definition better predicts clinical outcome.

The Feasibility of Angiosome-Targeted Endovascular Treatment in Patients with Critical Limb Ischemia and Foot Ulcer.

Background: To determine wound location according to the angiosome concept and to investigate the feasibility and success of angiosome-based revascularization in below-the-knee (BTK) arteries.

Methods: This was a retrospective study of 161 patients (67.5 ± 25.
