Closure of reversed patent ductus arteriosus (PDA) is generally accepted to be contraindicated due to case based evidence of worsened outcomes, but little is known about closure of left-to-right PDA with concurrent pulmonary hypertension (PH). This report describes three dogs presenting with varying severity of PH and clinical signs, all with documented left-to-right PDA. The PDA was closed in each case; either by surgical ligation or transarterial device occlusion, and follow up was available for a minimum of 8 months. Every case had a successful outcome with improvement or resolution of PH and associated clinical signs.
由于基于病例的证据表明逆向动脉导管未闭(PDA)闭合后预后恶化,一般认为逆向PDA闭合是禁忌的,但对于伴有并发肺动脉高压(PH)的左向右分流PDA的闭合情况却知之甚少。本报告描述了三只患有不同严重程度的PH和临床症状的犬,所有犬均记录有左向右分流的PDA。每只犬的PDA均成功闭合;要么通过手术结扎,要么通过经动脉装置封堵,并且至少随访了8个月。每例均获得成功结果,PH及相关临床症状得到改善或消除。
