- Stent-Assisted Coiling versus Coiling Alone in Unruptured Intracranial Aneurysms in the Matrix and Platinum Science Trial: Safety, Efficacy, and Mid-Term Outcomes
These authors analyzed data on 131 non-selected MCA aneurysms treated during a 6-year period. One month after treatment, permanent morbidity and mortality was 3.3% without significant differences according to technique used. The rate of recanalization was nearly 16%, also without differences according to technique, and re-treatment was needed in 7.6% of cases. A greater rate of complications occurred with balloon remodeling and only large aneurysm size predicted recanalization. The authors concluded that endovascular treatment of MCA aneurysms is safe, effective, and durable.
- Coiling of Large and Giant Aneurysms: Complications and Long-Term Results of 334 Cases
The long-term complications of coil treatment of giant intracranial aneurysms were assessed in 334 instances when treatment consisted of only coiling (225), stent-assisted coiling (88), parent vessel occlusion (14), or balloon-assisted coiling (7). The authors concluded that coiling of large and giant aneurysms has reasonable safety profiles with good clinical outcomes, but aneurysm reopening was common. Stent-assisted coiling had lower recurrence, retreatment, and new or recurrent hemorrhage rates with no additional morbidity compared with conventional coiling. Aneurysm size was a major determinant of recanalization, retreatment, new or recurrent hemorrhage, and poor outcome.
