Objective: To investigate the safety and clinical effect of self-expandable bare-metal stent for acute brachial artery injury. Methods: The clinical data of 18 cases with acute brachial artery injury were retrospectively analyzed. All patients underwent emergency angiography for confirmation of the diagnosis, and then received angioplasty and self-expandable bare-metal stent placement. Results: The technical success rate of the endovascular procedures was 100%, and the mean operative time was 50 (30–90) min. Thirteen patients underwent single-layered stent placement and 5 patients underwent two overlapping stents insertion, with a total of 23 self-expandable bare-metal stents deployed. Angiography immediately after stent placement showed that the blood flow of the injured brachial artery was restored, pseudoaneurysms disappeared and no stent stenosis or contrast agent extravasation was observed. All the 18 patients were followed up for an average period of 20.2 months, 17 patients had complete blood flow restoration or minor stenosis (required no treatment), while one patient developed a >50% in-stent stenosis, which was resolved by balloon dilation. No stent displacement, rotation or fracture was found, no ischemic necrosis occurred and no amputation surgery was needed during the follow-up period. Conclusion: Self-expandable bare stent placement is safe and effective in treatment of acute brachial artery injury, with satisfactory short- and medium-term efficacy.
