TY - JOUR T1 - Rupture of aneurysms in the immediate post-coiling period JF - Journal of NeuroInterventional Surgery JO - J NeuroIntervent Surg SP - 16 LP - 18 DO - 10.1136/neurintsurg-2012-010588 VL - 6 IS - 1 AU - Adam Andrew Dmytriw AU - Gwynedd Elaine Pickett AU - Jai J S Shankar Y1 - 2014/01/01 UR - http://jnis.bmj.com/content/6/1/16.abstract N2 - Purpose We present a series of cases featuring re-rupture of posterior communicating artery aneurysms in the immediate post-coiling period, where clots obscured the neck of the aneurysm during the procedure. We report on the incidence of re-rupture and discuss possible mechanisms behind this phenomenon. Methods This study included 462 aneurysms over a 10-year period which were treated with endovascular coiling. 137 of these were ruptured aneurysms. Radiographic and clinical information pertaining to the patients was collected. The immediate post-coiling period was defined as ≤3 days following the procedure. Results The incidence of re-rupture in the immediate post-coiling period was 1.4% (2/137). Of these two, one received recombinant tissue plasminogen activator and both received acetylsalicylic acid. One patient presented with adjacent hematoma on re-rupture. In both cases, clot obscured the aneurysm neck during the procedure. Conclusions Re-rupture of intracranial aneurysms in the immediate post-coiling period is an exceedingly rare complication, and the events leading to it have not been discussed at length. Repeat treatment, follow-up imaging and close observation are merited in the setting of re-rupture of a posterior communicating artery aneurysm. ER -
