- Long-Term Outcomes of the WEB Device for Treatment of Wide-Neck Bifurcation Aneurysms
With a mean follow-up of approximately 15 months, the authors evaluated 41 cases of wide-neck aneurysms. Overall, 78.8% of the aneurysms had complete occlusion in the last follow-up, and 19.5% required retreatment with additional endovascular devices. A good clinical outcome (mRS: 0–2) was obtained in 95.1% of the patients, and the overall treatment-related morbidity and mortality rates were 2.4% and 0.0%, respectively. They conclude that treatment of wide-neck bifurcation aneurysms with a WEB device is feasible with an acceptable safety and efficacy rate.
- Predictors of Cerebral Aneurysm Rupture after Coil Embolization: Single-Center Experience with Recanalized Aneurysms
The authors evaluated a total of 426 unruptured aneurysms and 169 ruptured aneurysms that underwent coil embolization in their institution between January 2009 and December 2017. Recanalization occurred in 38 (8.9%) of 426 unruptured aneurysms and 37 (21.9%) of 169 ruptured aneurysms. The Modified Raymond-Roy Classification on DSA was used to categorize the recanalization type. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.
