A, Concentric stenosis with a small residual lumen. B, An appropriately sized angioplasty balloon is inflated (arrows) in the lumen. C, Fracturing, fissuring, and subintimal dissection of the plaque greatly increase the crosssectional area of the lumen.,The primary mechanism of balloon angioplasty is controlled fracture of the obstructing plaque. This results in formation of fissures in the plaque itselt, and tearing of the edges of the plaque away from the adjacent normal intima. With proper oversizing of the balloon, the muscular media is stretched as well. Plaque is not remodeled, redistributed, or vaporized by the balloon.,第三十八頁，共四十二頁。,第二節(jié) 支架(zhīji224。,第三十五頁，共四十二頁。)成形術(shù)根本概念,五、支架(zhīji224。)分類 按支架外表情況分為： 裸支架(Bare stent) 覆膜支架〔Covered stent),第三十三頁，共四十二頁。,第二節(jié) 支架(zhīji224。chǎn)支架、wallstent、 symphony 激光切割支架：smart、zilver、palmaz、 saxxstent、lumingnexx 螺旋狀支架：IntraCoil、EndoCoil,第三十一頁，共四十二頁。,第二節(jié) 支架(zhīji224。)成形術(shù)根本概念,四、
