金属支架(Ultraflex stent)管是一种用一根具有弹性的铂合金单丝编织而成的金属网扩张支架,其具有自动扩张性,按放在各种原因引起的食管狭窄或食管吻合口内,当完全扩张后,可形成一个直径18mm管状网架,对狭窄部位起扩张支撑作用。我院自1993年11月至1994年4月用Ultraflex stent管治疗食管、吻合口
Ultraflex stent is a metal mesh expansion stent braided with an elastic platinum alloy monofilament. It has self-expanding properties and is placed under esophageal stenosis or esophageal anastomosis caused by various reasons. When fully expanded, it can form a tubular scaffold with a diameter of 18mm to support the stenosis. Ultraflex stent was used to treat esophageal and anastomosis in our hospital from November 1993 to April 1994.
