Abstract:
Objective To study the risk factors of intraprocedural re-rupture (IPR) of ruptured intracranial aneurysms, and the emergency management on this event and its efficacy. Methods The clinical data of 236 patients with ruptured intracranial aneurysms, admitted to our hospital from 2005 to 2009 and treated with embolization, were retrospectively analyzed; non-conditional logistic regression analysis was performed to analyze the risk factors of IPR of ruptured intracranial aneurysms. And the emergency management of IPR and its efficacy were concluded in 16 patients with IPR. Results The risk factors of IPR of ruptured intracranial aneurysms included small aneurysms with a diameter smaller than or equaling to 3.0 mm (OR=6.353, 95% CI: 1.266-31.894, P=0.025), aneurysms at distal part of Al and M1 segment of the anterior cerebral artery or middle cerebral artery (OR=35.449, 95% CI:3.053-411.642, P=0.004), atherosclerosis (OR=5.961, 95% CI: 1.215-29.260, P=0.028), mild vasospasm (OR=13.048, 95% CI: 1.220-139.574, P=0.034) and severe vasospasm (OR=14.826, 95% CI:1.871-117.488, P=0.011). Immediate reversal of heparin anticoagulation with protamine sulfate and rapid completion of coiling were performed in 16 patients (6.78%) occurred IPR. Emergent external ventricular drainage was performed in 12 patients having above Hunt-Hess grade Ⅲ:6 patients died; 1 was under persistent vegetative state and 9 fully recovered. Conclusion Small aneurysms, atherosclerosis,cerebral vasospasm and aneurysms at the distal part of Al or M1 segment may easily lead to IPR of ruptured intracranial aneurysms. Rapid completion of coiling combined with immediate reversal of heparin anticoagulation, and emergent external ventricular drainage performed in severe patients are confirmed to be the keys, which can decrease the death rate and improve the prognosis.
