Interventional embolization therapy for anterior choroidal artery aneurysms

This study aims to explore the clinical efficacy and surgical techniques of interventional embolization therapy for anterior choroidal artery aneurysms (AchANs). We retrospectively collected clinical data from 25 patients with AchANs treated with interventional therapy in our hospital from October 2021 to May 2024, including 16 cases with unruptured aneurysms and 9 cases with ruptured aneurysms. All 25 cases of aneurysms had relatively or absolutely wide necks and were treated with stent assisted coil embolization. All 25 patients achieved subtotal embolism. During interventional embolization surgery, 3 cases experienced choroidal artery thrombosis or spasm, and were treated with tirofiban simultaneously. Due to cerebral infarction, all the 3 patients had limited limb mobility on 1 side. After active treatment for cerebral infarction, one of them showed improvement in symptoms. Flexibly utilizing intervention techniques to ensure the patency of the anterior choroidal artery is crucial for interventional embolization of AchANs.
