Abstract

Objective To explore the complications and countermeasures in acute rupture intracranial aneurysm embolization with guglielmi detachable coil (GDC).Methods 146 patients with acute rupture intracranial aneurysm were embolized with GDC under the digital subtration angiography(DSA) imaging .Results Total occlusion was achieved in 136 cases (93%),over 90% in 9 cases(6%),less than 90% in one cases(1%). 4 patients died (2.7%); 9 rebleeded in the surgery;the parent artery were constricted in 4 cases; GDC escaped in 4 cases, 2 had over embolizations, 2 had thromboses; and 2 had hypertension hemorrhage after surgery.The rate of complications was 15.8%, and success rate 84.2%. Conclusion Better understanding of aneurysm and its parent artery angioanatomy, skill in embolization technique, correct judgment during treatment and improved embolic material are helpful to reduce the complications.
