Relationship between morphology of anterior communicating artery aneurysms and feasibility of endovascular coil embolization

Objective To summarize the experience of endovascular treatment for anterior communicating artery(AcoA) aneurysms and discuss the indications of the embolization,the aneurysm morphology and its relationship to the feasibility of endovascular coil embolization,the technical points of procedure and complications.Methods The clinical data of 36 cases with ruptured AcoA aneurysms treated by endovascular embolization were retrospectively reviewed. Results 34 of 36 cases were embolized successfully.Complete embolization was achieved in 22,5 aneurysms were 95%embolized,and 7 aneurysms 90%embolized.Rupture during embolization occurred in 2 patients and 1 died.Severe vasospasm occurred in 5.One patient died of complications following embolization.No rebleeding was found post embolization during a follow up from 6 to 58 months and 3 recurred.Conclusions Endovascular embolization is a minimally invasive,relatively safe and effective method for treatment of AcoA aneurysm.Aneurysm morphology should be considered to assess the probability of successful endovascular treatment for AcoA aneurysm.
