UNASSIGNED: OBJECT The purpose of this study was to report the authors' preliminary experience using self-expanding closed-cell stents deployed in small arteries (< 2 mm in diameter) to treat @entity438 . METHODS A total of 31 @entity1 were studied. All subjects met the following criteria: 1) they received an Enterprise stent for treatment of a wide-necked @entity439 or a dissecting @entity439 or as part of a stent-salvage procedure; and 2) they had an Enterprise stent deployed in a small parent artery (< 2 mm in diameter) that had no @entity731 . Procedure-related complications and follow-up sizes of the parent arteries were evaluated for safety and patency. RESULTS There were 16 @entity1756 and 15 unruptured @entity439 . Three (9.7%) of the 31 @entity1 experienced procedure-related complications, and they all were asymptomatic. Follow-up angiography was performed in 27 @entity1 (87.1%) (at a mean 15.5 months after surgery). Parent arteries with 2 acute angles (n = 4) were occluded in 3 cases (75.0%), and those with no acute angles (n = 13) or 1 acute angle (n = 6) showed 100% patency on follow-up angiography. There was a significant difference between the follow-up sizes (mean 1.72    0.30 mm) of parent arteries and their sizes (mean 1.59    0.26 mm) before treatment (95% CI - 0.254 to - 0.009 mm; p = 0.037, paired-samples t-test). CONCLUSIONS In the current series the deployment of self-expanding closed-cell stents in small arteries was safe and resulted in good patency, especially when the stents were deployed in segments of the parent artery with no acute angles or only 1 acute angle.
