- Abstract: Objective To evaluate the efficacy and safety of using stent semi-retrieval technique during mechanical thrombectomy(MT)for acute anterior cerebral artery(ACA)occlusion.Methods We made a retrospective analysis of 38 patients with acute ACA occlusion treated by stent semi-retrieval technique at Tangdu Hospital and Xi'an No.1 Hospital from June 2019 to September 2023.The successful recanalization,first-pass effect(FPE),perioperative complications and postoperative recovery of all the patients were analyzed.Modified thrombolytic test in cerebral infarction(mTICI)was used to evaluate the recanalization(unsuccessful recanalization,mTICI 0-2a;successful recanalization,mTICI 2b-3).FPE was defined as mTICI 3 after one thrombectomy.The clinical outcome was evaluated by modified Rankin Scale(mRS)3 months postoperatively.A good prognosis was defined as a mRS 0-2.Results Of the 38 patients,36(94.7％)got successful recanalization(mTICI 2b-3),with an FPE of 73.7％(28/38).Two cases of mild vascular spasm(5.3％)occurred during the mechanical thrombectomy,which completely relieved without further treatment.None of the 38 patients experienced vascular rupture or dissection,and no thrombus escaped during the thrombus removal process.There was no subarachnoid hemorrhage or parenchymal hemorrhage in the area related to ACA occlusion.Ninety days after operation,14 cases(36.8％)reached good outcome(mRS 0-2),18 cases(47.4％)reached mRS 3-5,and 6 cases(15.8％)died.Conclusion Our preliminary experience suggests that the stent semi-retrieval technique may be a safe and effective method for treating acute anterior cerebral artery occlusion.
