Abstract
Sixty-five middle cerebral artery (MCA) aneurysms in 59 patients treated by endovascular treatment (EVT) without the remodelling technique were analyzed. For ruptured aneurysms, the patients in bad condition are predominant and those with Fisher group four is 47.8% and with Hunt and Hess grade (HHG) IV or V are 43.5%. The clinical result is that 58.7% is in mRS 0–3, 21.7% in 4–5 and 19.6% in death. Contrary, 92.3% of the patients in HHG I-III resulted in mRS 0–3. Re-rupture was observed in two cases (4.4%). For all the aneurysms, thromboembolic complications were observed in 12.3% and those were predominant in the aneurysms greater than 10mm in diameter (p<0.05). Hemorrhagic ones occurred in 6.2% which were predominant in the aneurysms less than 10mm in diameter. No mortality was observed by the accidents. In follow-up angiography, Raymond classification was employed and Complete Obliteration or Dog Ear was observed in 24 of 43 cases (55.8%). Recanalization occurred in 10.5% of the cases with complete or almost complete obliterated aneurysms. These results suggested that EVT for the ruptured MCA aneurysms with good grade or the unruptured ones is feasible. Strict follow-up is important like the other aneurysms.
