Abstract：Objective: To investigate the safety and effectiveness of Acostream thrombus aspiration device in the treatment of acute lower limb arterial embolism (ALAE). Methods: A retrospective analysis was conducted on the clinical data of 11 patients with ALAE treated with Acostream thrombus suction device in the vascular department of Quzhou People’s Hospital from January 2022 to January 2023. Clinical observation indicators such as target vessel lesion length, intraoperative blood loss, balloon and stent use, complications (target vessel perforation, dissection, bleeding events, etc.), and symptom relief were recorded. Treatment effectiveness was evaluated through changes in lower limb ischemia WIFi grading and Cooley efficacy score. Outpatient follow-up was conducted at the 1st, 3rd, and 6th months after surgery to evaluate lower limb pain and target vessel patency.Results: All patients underwent surgery using the Acostream thrombus suction device, with intraoperative blood loss of 50-300 [190 (145, 245)] mL. Seven patients underwent balloon dilation without stent implantation. No target vessel flow limiting dissection or perforation occurred during the surgery. After the surgery, all patients had significantly reduced limb pain symptoms in a resting state, with no lower limb movement or sensory disorders in 9 cases, 1 left foot numbness, and 1 foot drop. The postoperative creatine kinase level, NRS pain score, ABI,and lower limb ischemia WIFi grading were significantly improved compared with those before surgery, showing significant differences (P<0.05). According to postoperative Cooley efficacy score, 9 cases were cured and 2 cases were good. During the follow-up period, 11 patients did not experience lower limb pain or intermittent claudication, and follow-up ultrasound showed smooth blood flow at the original occluded vessel. Conclusion:The Acostream thrombus suction device is safe, effective, and has high clinical application value in the treatment of ALAE.
