Efficacy and safety analysis of AcoStream thrombus aspiration device in the treatment of acute superior mesenteric artery embolism

Abstract

Objective Acute superior mesenteric artery embolism is a life-threatening disease caused by the abrupt interruption of mesenteric blood circulation, and the prognosis is very poor. Several studies have confirmed the efficacy and safety of percutaneous mechanical thrombectomy in acute superior mesenteric artery embolism, however, there are currently no literature reports on the latest percutaneous mechanical thrombectomy device—AcoStream™. In the present report, we summarize a series of cases and share our surgical experiences. Methods The clinical data of 10 patients (six men and four women, mean age 77.6 ± 7.4 years) with acute superior mesenteric artery embolism treated by AcoStream™ in our center from December 2022 to December 2023 were retrospectively analyzed. Based on the literature, we summarized the diagnosis, therapy, and surgical experience of acute superior mesenteric artery embolism. Results Percutaneous mechanical thrombectomy was performed for all the patients. The success rate of surgery reached 100% and no perioperative complications occurred. Abdominal pain was significantly relieved and the abdominal signs gradually disappeared in eight patients, while the other two patients still complained of abdominal pain during hospitalization, and eventually, they underwent resection of necrotic bowel. All the patients’ symptoms were significantly relieved and they were smoothly discharged from the hospital. Conclusions As shown in the present study, percutaneous mechanical thrombectomy using AcoStream™ is minimally invasive, safe, and efficient in the initial stage of acute superior mesenteric artery embolism. We believe that percutaneous mechanical thrombectomy can be a promising alternative in selected cases.
