In our a study a giant wide–necked vertebrobasilar junction aneurysms previously treated with endovascular detachable coils is followed up meticulously.The outcome was satisfactory
A 52 year old man presented with 2 year history of headache and was diagnosed as partially thrombosed giant aneurysm at the vertebrobasilar junction on cerebral angiographic examination. The patient underwent coil embolization by inserting a detachable and hydrogel coated coils successfully. He became symptom free after embolization on the next day. But 16 months later he was readmitted with a reccurrent episode of headache. Subsequent cerebral angiography revealed a new baby aneurysm formation at the same level near by the neck of the previous aneurysm.
Although giant vertebrobasilar junction aneurysm seems to be successfully blocked off initially, it should be remembered long- term follow-up as 1,5-2 years is required to further validate the importance of coil embolization technique.
