- Coil Type Does Not Affect Angiographic Follow-Up Outcomes of Cerebral Aneurysm Coiling: A Systematic Review and Meta-Analysis
This meta-analysis of the literature sought to identify differences between outcomes of patients treated with first- and second-generation aneurysm coils. Unfavorable outcome was defined as recanalization, less than 90% occlusion, and/or incomplete occlusion at follow-up. In 82 published articles, unfavorable outcomes were reported in 20% of patients treated with bare platinum coils, 23% with Matrix coils, 15% with HydroCoil, and 15% with Cerecyte coils. These differences were not statistically significant.
- Use of CT Angiography and Digital Subtraction Angiography in Patients with Ruptured Cerebral Aneurysm: Evaluation of a Large Multihospital Data Base
This article explores the usage of CTA and DSA in nearly 5000 patients with ruptured aneurysms. During a 5-year period, use of CTA more than doubled to 44% of all patients while the use of DSA remained stable (94–96%). The same trend was observed for patients undergoing coiling or clipping and following treatment the use of imaging increased from 41% to 48%, especially in clipped patients. The use of DSA as a second test is potentially redundant.
