Endovascular treatment has taken advantage of microsurgical clipping of the cerebral aneurysm since the advent of stent-assisted coiling. This is because several studies indicated that endovascular coil embolization had been associated with better outcomes than surgical clipping though coiling leads to a greater risk of rebleeding. Certainly, endovascular treatment has been a valuable therapeutic alternative for the cerebral aneurysm, though microsurgery still plays an important part in the treatment of cerebral aneurysm.
First, we discuss the apparent need for microsurgery to treat aneurysms in cases requiring revascularization to the distal of aneurysms, decompressive procedure due to intracranial hemorrhage, and to prevent repeated bleeding from the preciously coiled aneurysms. Moreover, microsurgery is relatively required to treat such cases as distal aneurysms, and aneurysms presented with mass effect. Second, we review the long-term follow-up outcomes of ruptured cerebral aneurysms treated at our hospital over 20 years between 1991 and 2011.
