Surgical clipping versus endovascular embolization for treatment of intracranial aneurysms:an analysis of postoperative results
2006
Objective To compare the postoperative results of endovascular embolization or surgical clipping in patients with intracranial aneurysms.Methods Two hundred and eighty-two patients with in- tracranial aneurysms treated with surgical clipping or endovascular embolization were reviewed between Sep- tember 2003 and May 2005.The postoperative complications,length of hospitalization and Glasgow Out- come Scale(GOS)score at discharge in patients with the two interventions were compared.Of the 282 pa- tients with intracranial aneurysms,7(2.5%)were failed in their endovascular embolization and were trea- ted with surgical clipping afterward.128(45.4%)were treated with endovascular embolization,99 (35.1%)were treated with surgical clipping,and 48 received neither surgical clipping nor endovascular embolization for various reasons.Results The good outcomes(GOS score 4,5)in the groups of endo- vascular embolization and surgical clipping were 91.4%and 79.8%,respectively;the poor outcomes (GOS score 1 to 3)were 8.8%and 20.2%,respectively;and their mortalities(GOS score=1)were 4.7%and 5.1%,respectively.Conclusion For the selected patients with intracranial aneurysms, endovascular embolization may be superior to surgical clipping.
