Intracranial aneurysm treated by endovascular embolism:an clinical analysis of 38 cases

Objective To explore the timing and technical points in treating intracranial aneurysms with endovascular embolization, and analyze its efficacy and the prevention of its complications. Methods Thirty-eight patients with intracranial aneurysm, admitted to our hospital from February 2006 to January 2009, were treated by endovascular embolism with the help of digital subtraction angiography (DSA). Twenty-six patients (27 aneurysms) were performed embolization with mechanical detachable coils (MDC) and 12 patients (12 aneurysms) were performed embolization with Guglielmi detachable coils (GDC). Their clinical data and efficacy were analyzed. Results Thirty-eight cases (39 aneurysms) were successfully embolized: 32 cases (84.2%) were fully embolized; 4 cases (10.5%) were 95% embolized and 2 cases (5.26%) were 90% embolized. Internal carotid artery thrombosis was found in 1 with wild-necked aneurysms after embolism and the patient was found hemiplegia and aphasia after 3 months. Bleeding caused by aneurysm rapture occurred in 2 and recovered after treatment Follow-up showed that 37 patients were successfully recovered except that 1 elderly patient died of lung infection and gastrointestinal bleeding. Conclusion Endovascular embolization, a minimally invasive, safe and effective technique, can effectively treat most patients with intracranial aneurysms.
