GOLAND, Javier et al. Experiencia con el tratamiento endovascular de los aneurismas del tope de la arteria basilar. Rev. argent. neurocir. [online]. 2006, vol.20, n.3, pp.115-120. ISSN 1850-1532.

Objective: We describe the early results obtained in a series of cases with basilar tip aneurysms treated by endovascular surgery with detachable coils. The results are compared according to the size of the neck and the sac of the aneurysm, the history of aneurysm rupture and neurological state. Method: A retrospective descriptive study was made in a cohort of 37 adults patients of both sexes with basilar tip aneurysms treated by endovascular surgery (period 1993 - 2006). Hunt- Hess scale was used for patients classification. The aneurysms were classified according to their size and the wide of the neck . The occlusion grade was classified in 4 categories: A (100%), B (> 95%), C (> 90%) and D(<90%). Results: Occlusion grade A was obtained in 68% of patients and occlusion grade B was obtained in 18% of patients.The morbidity was 7% in the non-SHA group and 28% in the SAH group. Morbidity was 9% in HH 0, 12.5% in grade HH 1-2, 58% in grade HH 3 and 50% in grade HH 4-5. Occlusion was grade A in 75% of the aneurysms with small sac and narrow neck and in the 55% of the aneurysms with a huge sac and broad neck. Global morbidity was 24% and global mortality was 5.4% Conclusion: According with our results, endovascular surgery was a good alternative for acute ruptured basilar tip aneurysms and incidental ones too, mainly when they had smaller sacs, narrower necks and a better neurological state.
