BACKGROUND AND PURPOSE: Blister-like @entity439 are uncommon but challenging lesions. Their small size and atypical location often make the diagnosis difficult. Microsurgery and endovascular procedures have been used for their treatment, but there is no consensus on the best treatment technique. We conducted a systematic review and meta-analysis of treatments and outcomes of these @entity455 . MATERIALS AND METHODS: We reviewed English-language articles on " @entity439 " published between January 1997 and November 2014. All studies reporting @entity1 with these @entity439 treated with surgery, endovascular procedures, or combined therapy with data on treatment modalities and clinical and/or angiographic outcomes were selected, including case reports and series. We performed a meta-analysis on the 2 largest treatment groups (surgery and endovascular management). RESULTS: Sixty studies with 334 @entity1 met our inclusion criteria. Surgery was performed in 114 @entity1 (34.2%), and endovascular treatment, in 199 @entity1 (59.5%). A combined treatment was used in 19 @entity1 (5.7%). A favorable outcome (mRS 0-2) was reported in 67.4% and 78.9% of @entity1 treated with surgery and with endovascular therapy, respectively (P = .034). CONCLUSIONS: Blister-like @entity439 are @entity455 . The choice of treatment method must be based on the initial clinical presentation and an analysis of the radiologic features of the lesion to select the best technique. Endovascular treatment seems to have lower morbidity and mortality and provides a better outcome compared with surgical approaches. Further prospective studies must be performed to confirm such interesting results.
