Conclusions
An IAT was observed in 18.9% of the 53 patients who
underwent surgical treatment for partially thrombosed
MCA aneurysms. Thrombectomy with temporary trapping
was the major risk factor for this complication.
Puncture of the wall of the thrombosed MCA branch
and intraarterial injection of a fibrinolytic agent is one possible
solution of this problem and has proven highly effective.
When fibrinolysis fails to restore blood flow, revascularization
of the distal portions of the thrombosed arteries
should be performed.
