DOI : 10.5137/1019-5149.JTN.31887-20.3 AIM: To assess the results, effectiveness, safety, and potentials of coiling and clipping of ruptured basilar apex aneurysms.

MATERIAL and METHODS: Included in this study were articles comparisons of outcomes of endovascular coiling and clipping of ruptured basilar apex aneurysms, published in the full-text form (from 1960 to March 31, 2020). Collected variables included: first author?s name, country, study period covered, publication year, the total number of patients and follow-up, the early postoperative mortality rate (PostOp-Mo) (30 days from the selecting treatment), permanent neurological deficit (PND), late mortality (LateMo) (after 1 month) and re-intervention (ReInt) (requiring surgery or coiling), for both groups. Outcomes reported by the eligible articles should be evaluated at least 6 months after subarachnoid hemorrhage or intervention (clipping or coiling).

RESULTS: After the preliminary searching, 210 articles were established to be nominees for further investigation. After the application of exclusion and inclusion criteria, there were 9 eligible articles left. The total number of patients was 582 (241 in the clipping group and 341 in coiling). Regarding PostOp-Mo, PND, and LateMo the final results demonstrated no potential significant difference between the two groups. Regarding the subgroup of patients with the ReInt the findings illustrated a statistically significant difference among the two groups [OR 2.33, CI 95%, (1.62? 3.09), Chi2=0.59 and p=0.001] with no heterogeneity (p=0.79 and I2=-69.27%).

CONCLUSION: Management complications, recurrences, and reintervention are considerably more frequent in endovascularly treated BX aneurysms. Keywords : Basilar apex aneurysms, Basilar tip aneurysms, Intracranial aneurysms, Posterior circulation aneurysms, Clipping
