Abstract

BACKGROUND: We investigated the complication rates of balloon-assisted coil embolization of ruptured and unruptured cerebral aneurysms dependent on their morphologic characteristics in angiography. METHODS: The study was a single-center retrospective analysis of all consecutive endovascular balloon-assisted coiling interventions performed between April 2008 and December 2013. Data were extracted from a prospective database on an intention-to-treat basis. We described the clinical (Hunt & Hess score, modified Rankin scale) and technical results (Raymond Roy aneurysm occlusion scale) and analyzed the rate of periprocedural complications with regard to aneurysm subgroups of bifurcation aneurysms versus sidewall aneurysms. RESULTS: There were 116 interventions performed on 108 patients (mean age: 51.7 +/- 11.1 years), with 70/116 emergency procedures (60%), 36/116 elective procedures (31%), and 10/116 elective procedures on recurrent aneurysms (9%). The balloon was used in 108/116 cases (93%). Among the cases, 76/116 were bifurcation aneurysms and 40/116 were sidewall aneurysms. Periprocedural complications, such as rerupture, thrombus formation, distal embolism, coil-loop protrusion, and coil migration, occurred in 26/116 cases (22%). Complications occurred significantly more often in ruptured than unruptured bifurcation aneurysms (23 vs. 3 events, P < 0.05). There was a significantly higher rate of complications in bifurcation aneurysms compared with sidewall aneurysms (17% vs. 3%, P = 0.03). Six periprocedural complications were associated with a permanent neurologic deficit (6% of cases), all of which occurred in the subgroup of acutely ruptured aneurysms. CONCLUSION: The risk of periprocedural complications in balloon-assisted coil embolization of ruptured and unruptured cerebral aneurysms is linked to the morphologic presentation of the aneurysm; the complication rate was significantly higher in bifurcation aneurysms.
