Oxygen Saturation Increase in Ischemic Wound Tissues after Direct and Indirect Revascularization.

Background: The primary approach for treating ischemic wounds is restoring oxygen supply to the ischemic region. While direct angiosomal revascularization is often associated with better post-operative wound healing and limb salvage, its superiority over non-angiosomal revascularization remains controversial. This study aimed to compare intraoperative tissue oxygen saturation changes in ischemic zones following either direct or indirect revascularization in below-the-knee arteries.

Abdominal Aortic Aneurysm Diameter versus Volume: A Systematic Review.

Unlabelled: Recently, AAA volume measurement has been proposed as a potentially valuable surveillance method in situations when diameter measurement might fail.

Objective: The aim of this systematic review was to analyze the results of previous studies comparing AAA diameter and volume measurements.

Methods: A systematic search in PubMed, Cochrane, and EMBASE databases was performed to identify studies investigating the use of diameter and volume measurements in AAA diagnosis and prognosis in English, German, and Russian, published until December 2022.

Measurement of Revascularization Effect Using Near Infrared Spectroscopy in Below the Knee Arteries.

Background: Current methods evaluating tissue ischemia are based mainly on evaluating blood flow and not tissue perfusion. However, diabetes mainly affects small vessels and blood flow evaluation is insufficient. The aim of the trial was to evaluate the feasibility of NIRS in measuring perfusion changes during chronic total occlusion (CTO) revascularization in below the knee (BTK) arteries.
