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. Methods: This prospective observational study included patients undergoing direct and indirect below-the-knee endovascular revascularizations. Assignment to the groups was not randomized. Near-infrared spectroscopy was used to monitor rSO2 changes near the ischemic wounds intraoperatively. The changes were compared between the groups. Results: 15 patients (50%) underwent direct angiosomal revascularization, while an equal number of patients underwent indirect revascularization. Overall, a statistically significant increase in regional oxygen saturation was observed after revascularization (p = 0.001). No statistically significant difference was found between the direct and indirect revascularization groups (p = 0.619). Conclusions: This study revealed a minor difference in the oxygen saturation increase between the angiosomal and non-angiosomal revascularization groups. Such a finding indicates that the clinical significance of angiosomal revascularization is negligible and might be concealed by confounding factors, such as the vessel diameter and outflow impact on the restenosis rate.

Background and Objectives: The Walking Impairment Questionnaire (WIQ) is a short and simple tool to measure walking impairment for patients with peripheral arterial disease requiring no special equipment or trained staff. The aim of this study was to assess the validity and reliability of the culturally adapted Lithuanian WIQ version in patients with intermittent claudication. Materials and Methods: In total, 40 patients with intermittent claudication and ankle–brachial index < 0.90 participated in this study. Reliability and internal consistency of the questionnaire were assessed by the intra-class correlation coefficient (ICC) and Cronbach’s alpha (α), respectively. Validity was determined by correlations between the WIQ scores and a subjective test (Quality of Life 5 Dimension Questionnaire 3 Level Version (EQ-5D-3L)) and objective tests (6 min walk test (6MWT), treadmill test, and ankle–brachial index). Results: The test–retest reliability was assessed as excellent with an intraclass correlation coefficient of 0.90. The values of Cronbach’s alpha were 0.957 (I time) and 0.948 (II time) and indicated an excellent internal consistency. Statistically significant Spearman correlations were detected between the WIQ and walking distances on the 6MWT (rho 0.514, p < 0.001) and treadmill test (rho 0.515, p < 0.001). Higher WIQ scores were associated with longer walking distances and duration. Moderate negative and low negative correlations were found between the WIQ and EQ-5D-3L scores. Conclusions: The Lithuanian version of culturally adapted WIQ demonstrates reliability and validity for patients with intermittent claudication, supported by two different walking tests showing statistically significant moderate Spearman correlations.

Background/Objectives: Management of prehepatic portal hypertension involves endoscopic and medical therapies with subsequent shunting if symptoms persist. Lately, surgical shunts, particularly the Meso-Rex shunt, are increasingly considered early in the disease course, offering benefits such as minimized hyperammonemia, improved somatic growth, and preservation of liver function. Our study evaluates post-operative outcomes after different surgical procedures in children with prehepatic portal hypertension. Methods: This single-centre retrospective case series included six children undergoing surgical shunting for prehepatic portal hypertension over a 5-year period. Medical records before and after surgery, followed for an average of 4.0 years, were analyzed. Results: Five patients underwent a Meso-Rex bypass, while one patient underwent a mesorenal shunt procedure. All cases showed clinically significant regression of esophageal varices six months post-surgery. Thrombocyte as well as leukocyte count significantly increased in five out of six patients during the long-term follow-up. Currently, five out of six surgically formed shunts (83%) continue to function normally. Conclusions: Our study supports early surgical intervention for improved long-term outcomes in managing portal hypertension, reducing complications like hypersplenism and variceal bleeding. Early consideration and ongoing monitoring are crucial for long-term success in children with portal hypertension.
