Abstract：Objective To investigate the surgical treatment and outcomes of Hasan type A chronic internal carotid artery occlusion(CICAO).Methods The clinical data of 32 patients with Hasan type A CICAO admitted from January 2019 to December 2022 were retrospectively analyzed.After surgery,the Arterial Occlusive Lesion(AOL)scale was used to measure the degree of recanalization,with grade 2～3 indicating successful reperfusion.The postoperative restenosis(stenosis rate≥50%)was evaluated according to the North American NASCRT method.The patients were followed up for 6 months,and the prognosis was evaluated using the modified Rankin scale(mRS)score.Results Sixteen patients underwent endovascular treatment,and 16 underwent hybrid surgery;successful reperfusion was achieved in 22 patients,while 10 patients failed;the treatment success rate was 68.7%,with a success rate of 62.5%(10/16)for endovascular treatment and 75.0%(12/16)for hybrid surgery.Seven patients(4 endovascular treatment,3 hybrid surgery)had postoperative complications,including hyperperfusion syndrome in 2 patients,cavernous sinus in 2 patients,dissection in 2 patients,and stent thrombosis in 1 patient.Three patients had restenosis,including 1 with clinical symptoms who underwent Superficial temporal artery-middle cerebral artery bypass.At 6 months,a mRS score of 0～2 was achieved in 27 patients and a mRS score of 3～5 in 5.Conclusions Endovascular treatment and hybrid surgery for patients with Hasan type A CICAO are safe and effective.Compared with endovascular treatment,hybrid surgery has a higher technical success rate and a lower incidence of surgical complications.
