Clinical observation of coil embolization of ruptured tiny intracranial aneurysms / 中国脑血管病杂志

ABSTRACT

Objective: To investigate the feasibility and efficacy of endovascular embolization of ruptured tiny intracranial aneurysms. Methods: The clinical data of 11 patients with ruptured tiny intracranial aneurysm were analyzed retrospectively. All the patients with subarachnoid hemorrhage (SAH) were diagnosed by CT and microcoil embolization was performed after being confirmed by digital subtraction angiography (DSA). Results: Circled digit oneNine patients had anterior communicating artery aneurysm, 1 had anterior choroidal artery aneurysm, and 1 had pericallosal artery aneurysm. At admission, the Hunthess grade I was 3 cases, grade II was 5, grade III was 2, and grade IV was 1. Circled digit twoAll the patients were embolized successfully, 6 of them were embolized completely, and 5 were embolized incompletely (during 3 to 6 months DSA follow-up, they were all obliterated completely). The GOS were 5 in 9 patients, GOS 4 in 1 patient, and 1 patient died after the procedure. No technology-related complications were observed. Circled digit threeAt 3 to 6 months after procedure, 6, 2, and 2 patients were followed up with DSA, magnetic resonance angiography (MRA) or telephone respectively. The aneurysms were all obliterated completely, the GOS were 5 in all patients, and no rebleeding occurred. Conclusion: Endovascular embolization of ruptured tiny intracranial aneurysms in intracranial anterior circulation is safe and feasible, and the result of short-term follow-up is good.
