In-Hospital Risk Factors for Reintervention and Amputation in Brachial Arterial Trauma.

ABSTRACT

INTRODUCTION: Brachial artery trauma is a rare but potentially devastating injury. There is little data regarding risk factors for reintervention and amputation prevention in this population, as well as anticoagulant (AC) and antiplatelet (AP) regimens and outcomes after discharge in trauma patients with vascular injuries requiring repair. This study aims to identify in-hospital risk factors for reintervention and amputation and stratify outcomes of follow-up by discharge AC or AP regimen. METHODS: The AAST Prospective Observational Vascular Injury Trial database was queried for all patients who underwent traumatic brachial arterial repair from 2013 to 2022. Patients were evaluated by need for reintervention, amputation, and outcomes at follow-up by AC or AP regimen. RESULTS: Three hundred and eleven patients required brachial repair, 28 (9%) required reoperation, and 8 (2.6%) required amputation. High injury severity score and an increased number of packed red blood cells and platelets showed a significant increase for reoperation and amputation. Damage control and shunt use were significant for the need to reoperate. Seventy-four percent (221/298) of patients were discharged with postoperative AC or AP regimens. There was no significant difference of short-term follow-up by type of AC or AP regimen. CONCLUSIONS: Damage control and temporary shunt may lead to additional operations but not an increase in amputations. However, anticoagulation intraoperatively and postoperatively does not appear to play a significant role in reducing reintervention. It also suggests that there is no increase in short-term follow-up complications with or without AC or AP therapy.
