ABSTRACT
Objective To evaluate the therapeutic efficacy of endovascular embolism in treating aneurysms located at the bifurcation of middle cerebral artery. Methods During the period from Jan. 2009 to May 2013 at authors’ hospital, a total of 21 patients with intracranial aneurysms located at the bifurcation of middle cerebral artery were treated with interventional embolization. Of the 21 cases , steel coils were used in 7, stent-assistant embolization was adopted in 12, and dual-microcatheter technique was employed in 2. The results were analyzed. Results Postoperative angiography showed that complete embolization of the aneurysm was achieved in 14 patients, residual neck was detected in 2 patients and subtotal obliteration of the aneurysm was seen in 5 patients. Procedure-related complications occurred in 2 patients, including cerebral bleeding during operation (n = 1) and postoperative small area cerebral infarction. Seventeen patients were followed up for 6 months, and follow-up angiography showed that no recurrence of aneurysm was seen. Conclusion For un-ruptured, or ruptured with no big hematoma, intracranial aneurysms located at the bifurcation of middle cerebral artery, endovascular interventional embolization is the treatment of choice.
