Background:
Reports about the use of flow diverter stents (FDS) in the acute setting of subarachnoid hemorrhage (SAH) are limited. This article presents a single center experiences based on 45 consecutive cases with emphasis on complication rates and clinical and radiologic outcomes.
Methods:
A prospectively maintained database of all cases treated with FDS as a stand-alone or adjunct device was retrospectively reviewed. All patients treated within 30 days of SAH were included. Records were made of clinical presentation, details of endovascular treatment, procedural complications, clinical outcome, and degree of occlusion on follow-up.
Results:
In this study 45 patients (48.9% females; mean age 58.8 ± 12.4 years) were included. Flow diversion was performed after a median of 4 days. The procedural complication rate was 13.3% resulting in 2.2% permanent morbidities and 4.4% mortalities. No major hemorrhagic complications related to antiplatelet therapy were recorded. Immediate complete occlusion was achieved in 13.3%. Among survivors, complete occlusion was achieved in 94.6%. Excellent clinical outcome was recorded in 68.9% and 81.6% of the total population and survivors, respectively. There were no records of rebleeding from the target lesions.
Conclusion:
Flow diversion is an attractive alternative strategy for management of acutely ruptured aneurysms with high rates of delayed complete occlusion and acceptable complication rates.
