Endovascular nuances of the treatment of very small intracranial aneurysms

摘要

Adjunct devices, like compliant balloons or stents, can be useful to mitigate these nuances, although they should be weighed against their contribution to treatment complexity and risk. As cited by the authors and worth mentioning further, in a meta-analysis of 422 very small aneurysms (61 % ruptured) treated by endovascular means (excluding flow diversion), with adjunct devices used in 31.8%, overall short-term and long-term complete or nearly complete occlusion rates were 95.3% and 93.5%, respectively, with 5.4% requiring retreatment (1). The overall combined morbidity and mortality rate from intra-procedural ruptures, thromboembolic complications, or late rebleeding was 7.3%, with an overall intraprocedural rupture rate of 8.3% (1).
