Y-configured double stent technique is useful for coil embolization of a bifurcation wide neck aneurysm while preserving the patency of the two important vessels. However, if the important vessels emanating directly from the aneurysm comprised four vessels, two vessels not deployed, Y-stents might not be preserved with the Y-stent technique by itself. We report a case treated with Y-configured double stent-assisted coil embolization with a double microcatheter technique for complex basilar bifurcation aneurysm. A 78-year-old woman presented with a subarachnoid hemorrhage (SAH) of poor grade. CT-angiography showed a wide neck and shallow aneurysm of complex basilar bifurcation involving both posterior cerebral arteries (PCAs) and superior cerebellar arteries (SCAs). In the chronic stage of SAH, Y-configured double stent-assisted coil embolization with a double microcatheter technique was performed. After Y-stent (two Enterprise) deployment from both the PCAs to the basilar artery, coil embolization of a basilar bifurcation aneurysm was performed using a double microcatheter technique to preserve both SCAs.
