- Endovascular Treatment of 300 Consecutive Middle Cerebral Artery Aneurysms: Clinical and Radiologic Outcomes
Controversy about the best treatment method for MCA aneurysms persists and these authors report the results of endovascular treatment of these lesions in a large series in which 295 such aneurysms were treated during a 17-year period and the results retrospectively analyzed. Complete occlusion was achieved in 94% and treatment failed in 4.3%. Procedure-related morbidity and mortality occurred in nearly 8%. Death occurred in 13.6% of patients and 4.3% needed to be re-treated. Thus, endovascular treatment of MCA aneurysms is acceptable as a primary treatment.
- 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.
