472-86 | Factors Predicting Outcomes in Patients with Critical Limb Ischemia After Multidisciplinary Team Treatment: A 5-year Single-Center Retrospective Review-JVU 472-86

JVU 472-86

Pdf Summary

This article is a retrospective review of patients with critical limb ischemia (CLI) who were referred to a multidisciplinary limb salvage committee over a 5-year period. The study aimed to identify factors that predict outcomes in these patients after multidisciplinary team treatment. The factors assessed included the modified Frailty Index (mFI), Society for Vascular Surgery (SVS) WIfI wound score, and pedal acceleration time (PAT). The outcomes analyzed were 1-year amputation-free survival (AFS-1), independence, and major complications.<br /><br />The study included 81 patients who underwent either open or endovascular revascularization. The results showed that 1-year amputation-free survival was positively correlated with post-procedure PAT and inversely related to the severity of the wound at presentation. Independence at 1 year was linked to wheelchair dependence prior to intervention. An mFI ≥6 was associated with an increased incidence of major complications at 1 year.<br /><br />The study highlights the importance of post-procedural PAT in predicting amputation-free survival and the negative impact of severe wound presentation on outcomes. It also emphasizes the significance of wheelchair dependence prior to intervention as a predictor of independence. The mFI was found to be associated with an increased risk of major complications.<br /><br />Overall, the study suggests that assessing frailty and considering factors such as post-procedural PAT, wound severity, wheelchair dependence, and mFI can help predict outcomes and guide decision-making in managing patients with CLI. The findings suggest that a multidisciplinary approach, led by vascular technologists, can improve outcomes for these patients, particularly in terms of limb salvage.
