OBJECTIVE: The Enterprise stent is used for endovascular treatment of @entity438 . The purpose of this study was to evaluate delayed @entity1031 (DTEs) that developed more than 30 days after Enterprise stent-assisted embolization (SAC) and its associated risk factors. METHODS: There were 125consecutive @entity1 (90 @entity1 and 35 @entity1 ; mean age, 56.1 years) who received endovascular treatment for126 @entity438 using the Enterprise stent during December 2008 to May 2011. A DTE was defined as a symptomatic or asymptomatic @entity385 with positive findings on brain magnetic resonance imaging in the territory of the treated @entity439 and transient @entity63 attack. Asymptomatic in-stent @entity850 and occlusion were excluded. RESULTS: During a mean follow-up of 32.4 months, DTEs occurred in 10 @entity1 (7.93%). DTEs occurred on antiplatelet therapy (dual medication, n=2, 2 months after embolization; single medication, n=6, 10-20 months after SAC) or after discontinuation of antiplatelet therapy (n=2, 14 months after embolization). Multivariate analysis showed that current smoking (p=0.005) and maximum parent artery diameter >4.5mm (p=0.003) were associated with DTE. CONCLUSIONS: SAC with the Enterprise stent poses a considerable risk of DTE. Our results suggest that a longer duration of antiplatelet therapy and clinical follow-up may be warranted for cases with suggested risk factors. The protocol for antiplatelet therapy after SAC should be determined in a large prospective trial.
