Abstract:

Objective To explore the key technique of endovascular embolization of ruptured tiny intracranial aneurysms, and evaluate the clinical efficacy and safety of this treatment. Methods A retrospective analysis of clinical data of patients with subarachnoid hemorrhage was performed to rupture tiny intracranial aneurysm which was treated by endovascular embolization in Yunfu People’s Hospital during April, 2014 and October 2016, and to evaluate the clinical efficacy, intraoperative complications and the prognosis. Results All 23 patients were treated with endovascular coil embolization under the general anesthesia. Among which, 17 of them were only with coil and 6 were with stent-assisted embolization. There were complete embolization in 19 cases (82.61%), aneurysm neck residue in 4 cases (17.39%) and all parent arteries were normal. Aneurysm were followed up for 6-30 months, and no bleeding recurred was found. The parent artery in one (4.35%) case was occluded by a bit of protruding coil and restored to normal after planting Enterprise stent. One (4.35%) with residual aneurysm neck recurred after 1 year and was successfully treated with stent-assisted endovascular embolization. Among 23 patients, the mRS scale scores in 21 cases were 0 at 6 months after procedure, and 2 cases were 2. Conclusion Endovascular embolization for the treatment of ruptured tiny intracranial aneurysms is safe and effective, and the result of short-term follow-up is good.
