Objective: Endovascular treatment as well as surgical treatment has become a treatment method for the management of the intracerebral aneurysms. The authors present the results of surgical and endovascular treatment of middle cerebral artery (MCA) bifurcation aneurysms.
Methods: From 1999 to 2005, 54 MCA bifurcation aneurysms were treated with surgical or endovascular methods at our hospital. Forty two patients had ruptured aneurysms and 12 had unruptured aneurysms. Of 54 aneurysms, 33 were treated with surgical clipping, 20 with Guglielmi detachable coil (GDC) embolization and 1 with cross over treatment. The medical, radiological and operation records were reviewed retrospectively.
Results: Of the 54 patients, 37 (68.5%) were female and 17 (31.5%) were male. In the surgically treated group, 22 (66.7%) experienced excellent or good outcomes (GOS 5 or 4), 8 (24.2%) had fair or poor outcomes (GOS 2 to 3), and 3 (9.1%) died (GOS 1). In the endovascularly treated group, 15 (75%) had excellent or good outcomes, 1 (5.0%) had fair outcomes (GOS 3), and 4 (20%) died. Symptomatic vasospasm revealed 9 (25.7%) in the surgically treated group, and 6 (30%) in the endovascularly treated group. Seven (20.5%) complications occurred from the surgical group, 3 (15%) from the endovascular group. On logistic regression analysis, there were no significant differences in GOS and vasospasm between surgically treated group and endovascularly treated group (p=0.788, 0.643, respectively).
Conclusion: Endovascular treatment of MCA bifurcation aneurysms results in clinical outcome equal to the outcome of surgical treatment of MCA bifurcation aneurysms and it can be a good alternative method for MCA bifurcation aneurysms treatment.
