BACKGROUND AND PURPOSE: Outcomes of endovascular treatment of very small @entity438 are still not well-characterized. Recently, several series assessing coil embolization of tiny @entity439 have presented new promising results. Thus, we performed a systematic review and meta-analysis of studies evaluating endovascular treatment of very small @entity438 . MATERIALS AND METHODS: We conducted a computerized search of Scopus, Medline, and the Web of Science for studies on endovascular treatment of very small ( <=3 mm in diameter) @entity438 published between January 1996 and May 2015. Using a random-effects model, we evaluated clinical and angiographic outcomes. RESULTS: Twenty-two studies with 1105 tiny @entity439 (844 ruptured and 261 unruptured) endovascularly treated were included. Postoperative and long-term complete occlusion was achieved in 85% (95% CI, 78%-90%) and 91% (95% CI, 87%-94%) of @entity439 , respectively. The recanalization rate was 6% (95% CI, 4%-11%) and retreatment occurred in 7% (95% CI, 5%-9%) of cases. Seventy-nine percent (95% CI, 64%-89%) of @entity1 had good neurologic outcome at long-term follow-up. Intraprocedural @entity397 occurred in 7% (95% CI, 5%-9%) of the coiling procedures, while @entity1031 complications occurred in 4% (95% CI, 3%-6%). CONCLUSIONS: Coil embolization of very small @entity438 can be performed safely and effectively. In the case of unruptured @entity439 , procedure-related complications are not negligible. @entity1 and providers should consider such risks when engaged in a shared decision-making process.
