Abstract:
Objective To evaluate the short term efficacy and safety of the new bioabsorbable polymeric coils (Matrix) system. Methods Sixty two patients with intracranial aneurysms were treated with Matrix coil or combined with Guglielmi detachable coils (GDC). Results All 62 cases of aneuryem were successfully embolized including 29 with Matrix alone, while 33 with Matrix and GDC. Total occlusion was achieved in 49 aneurysms and subtotal in 13. One patient experienced with aneurysmal rupture bleeding and two had thromboembolic complications during the procedure. Two patients died, 3 had severe neurologic deficits, while others recovered well in the clinical follow up for 3-5 months. Ocularmotor nerve palsy occurred in 2 cases and resolved 2 weeks later. 3-6 months angiographic follow up in 25 patients showed the result was stable with no stenosis in parent artery. Conclusions Matrix system may release the mass effect and prevent recanalization after endovascular embolization of cerebral aneurysms. Long tesm follow up is necessory for further investigation.
