【摘要】目的：总结锁骨下动脉蹼样改变（即锁骨下动脉有向其管腔内突出膜样结构）的彩
色多普勒超声特征。方法：收集我院经颈部血管超声检查提示锁骨下动脉蹼样改变的患者
213 例，观察锁骨下动脉蹼样改变发生的位置、长度、厚度、突向管腔内膜样结构中膜的长
轴与锁骨下动脉长轴形成的夹角，以及蹼样改变对应部位有无斑块以及是否造成管腔狭窄、
盗血及其程度，总结锁骨下动脉蹼样改变的超声特征。结果：213 例患者共发现 217 例处锁
骨下动脉蹼样改变，其中发生于右侧 195 处（89.9%），左侧 22 处（10.1%）；蹼样改变长
度 1.2～8.6mm，厚度 0.5～1.9mm。突向管腔内膜样结构中膜的长轴与锁骨下动脉长轴形成
的夹角中，直角 17 个、钝角 181 个、平角 19 个。蹼样改变对应部位不伴有斑块 97 处，伴
有斑块 120 处。蹼样改变造成管腔轻度狭窄 58 处，中度狭窄 3 处；蹼样改变与斑块共同造
成管腔轻度狭窄 65 处，中度狭窄 11 处，重度狭窄 2 处；78 处无管腔狭窄。蹼样改变造成
隐匿盗血 15 处，部分盗血 6 处；196 处无盗血。结论：锁骨下动脉蹼样改变的超声表现具
有一定的特征性，彩色多普勒超声可作为锁骨下动脉蹼样改变筛查的首选方法。

ABSTRACT：Objective To summarize the color Doppler ultrasonography characteristics of
subclavian artery webbed changes（that is，the subclavian artery has a membranous structure
protruding into its lumen. Methods A total of 213 patients with the subclavian artery webbed
changes in our hospital were enrolled. The location，length，thickness of the webbed changes of
the subclavian artery，the angle between the long axis of the membrane protruding into the
intimal structure of the subclavian artery and the long axis of the subclavian artery，the presence
of plaque at the corresponding site of the webbed changes，lumen stenosis，blood steal and its
degree were observed. The ultrasonic characteristics of the webbed change of the subclavian
artery were summarized. Results There were 217 subclavian artery webbed changes in 213
patients，195 （89.9%）on the right side and 22 (10.1%) on the left side. The webbed changes
length 1.2～8.6mm and the thickness 0.5～1.9mm.There were 17 right angles，181 obtuse angles
