Objective To summarize the diagnosis and endovascular treatment of middle cerebral artery (MCA) bifurcation aneurysm. Methods Between January 2010 and June 2011, 32 patients with MCA bifurcation aneurysm underwent endovascular treatment. There were 12 males and 20 females, aged 49.5 years on average (range, 35-81 years). All patients had sudden headache, 2 cases had disturbance of consciousness and hemi plegia, and 22 cases had a history of
hypertension. Before operation, 10 cases were classified as Hunt-Hess level I, 15 cases as level II, and 7 cases as level III; 24 cases were classified as Fisher level II and 8 cases as level III. The patients underwent coil embolization using single microcatheter in 16 cases, using double microcatheter in 7 cases, using balloon-assisted in 4 cases, using single stent in 4 cases, and using double stent in 1 case. Results The results of postoperative immediate digital subtraction angiography showed that 30 patients achieved dense embolization, and 2 patients using single microcatheter achieved approximated dense embolization. Among them, 18 cases suffered extensive subarachnoid hemorrhage, thus lumbar puncture continued drainage was performed for 3-7 days; the other 14 cases had l ittle subarachnoid hemorrhage, lumbar puncture released hemorrhagic cerebrospinal fluid discontinuously, and after
1 week, head CT demonstrated that subarachnoid hemorrhage was significantly decreased. At 1 day after surgery, 2 patients had local cerebral ischemia; after Nimotop and other drugs were used for 1 week, the symptom was alleviative. All 32 patients were followed up 4 to 17 months. No aneurysm rupture and bleed occurred during follow-up; no other complications or sequelae was observed except for 3 cases of hemiparesis and 1 case of aphasia. The computed tomographic angiography examination showed no re-open of dense embolized aneurysm at 3, 6 months, and 1 year after surgery. Conclusion As long as appropriate intervention treatment method is chosen, endovascular treatment of MCA bifurcation aneurysm is safe and effective.
