Abstract

Valvular pulmonic stenosis has been successfully treated in dogs via minimally invasive transcatheter balloon dilation procedures for almost 20years. Supravalvular pulmonic stenosis however is not amenable to balloon dilation procedures. Although several surgical procedures are described for treatment of pulmonic stenosis, the morbidity and mortality of these procedures are significantly higher than for transcatheter approaches. Two cases of supravalvular pulmonic stenosis are presented, one acquired and one congenital, which were successfully treated with transcatheter intravascular stent placement. The procedure alleviated the stenotic lesion and resolved clinical signs.

摘要

近20年来，犬的瓣膜性肺动脉狭窄已通过微创经导管球囊扩张术成功治疗。然而，瓣上肺动脉狭窄不适合球囊扩张术。尽管有几种外科手术方法用于治疗肺动脉狭窄，但这些手术的发病率和死亡率明显高于经导管治疗方法。本文介绍了两例瓣上肺动脉狭窄病例，一例为后天性，一例为先天性，均通过经导管血管内支架置入术成功治疗。该手术缓解了狭窄病变并消除了临床症状。
