Endovascular Treatment of Ruptured Intracranial Aneurysms (a Report of 24 Cases)

Objective To explore the curative effect of endovascular treatment on ruptured intracranial aneurysms and its technique. Methods Twenty-four patients with spontaneous subarachnoid hemorrhage confirmed by CT or MRI underwent the DSA examination, which showed that the diameters of intracranial aneurysms ranged from 2 mm to 5 mm in 10 aneurysms, did from 6 mm to 15 mm in 16 ones and did from 16 mm to 25 mm in 2 ones. There were 28 aneurysms in 24 patients. There were 3 aneurysms in 1 patients and there were 2 aneurysms in each of 2 patients. According to Hunt-Hess grading, of 24 patients, 5 belonged in grade Ⅰ, 8 in grade Ⅱ, 8 in grade Ⅲ, 2 in grade Ⅳ and 1 in grade Ⅴ. The aneurysms were embolized with Guglielmi detachable coils (GDC) in 24 patients. Two aneurysms were endovascularly embolizated and 1 aneurysms were clipped in the patients with 3 aneurysms. Results Of 24 patients with intracranial aneurysms, 21 were clinically cured, 1 was disabled (hemiplegia) and 2 died. The following-up from 3 to 24 months showed that 22 survival patients were recovered well, and did not suffered from re-bleeding. Conclusions Endovascular embolization by GDC is safe and effective treatment in patients with ruptured intracranial aneurysms, in whom there are few complications, and low disabled and death rates after undergoing endovascular embolization.
