Giant fusiform aneurysm at the basilar trunk treated with endovascular coil occlusion following bypass surgery for the flow diversion / 대한뇌혈관외과학회지

Giant fusiform aneurysms at the basilar trunk tend to have a poor natural history and surgical management for these aneurysms remains controversial. For these aneurysms, basilar trunk occlusion with endovascular coiling is difficult when the collateral supply from the carotid circulation is relatively poor. Interestingly, we herein present a successfully treated case of a partially thrombosed giant fusiform aneurysm at the basilar trunk with relatively poor collateral supply using endovascular coil occlusion following bypass surgery (superficial temporal artery-radial artery-superior cerebellar artery anastomosis).
