What is the role of clipping surgery for ruptured cerebral aneurysms in the endovascular era? A review of recent technical advances and problems to be solved

Abstract

Craniotomy and clipping have been robust treatments for ruptured cerebral aneurysm for more than 50 years, with satisfactory overall outcomes. Technical advances, such as developments in microsurgical tools and equipment, adjunctive therapy, and novel monitoring methods enable safer and more efficient treatment. However, overall surgical results have not shown any major improvements, as outcomes are mainly determined by the damage from initial bleeding, and new treatment strategies are not always free from associated complications and problems. Recent advances in endovascular treatment are shifting the treatment for ruptured cerebral aneurysm from craniotomy and clipping to intravascular coil embolization. However, craniotomy and clipping are very important for the treatment of ruptured cerebral aneurysm. This paper discusses recent advances and future perspectives in the field of clipping surgery for ruptured aneurysms.
