报道对11例肺动脉瓣狭窄患者施行经皮球囊肺动脉瓣成形术(PBPV)治疗的体会。11例患者经手术后,右室收缩压由术前75.5±49.7降至38.7±13.8mmHg(P<0.01);肺动脉收缩压由术前15.2±6.5升至21.0±5.0mmHg(P<0.01);肺动脉平均压由术前8.5±2.9升至9.8±3.6mmHg(P<0.05);肺动脉瓣跨瓣压差由术前60.1±16.9降至33.5±16.6mmHg(P<0.01)。在1年后随访,跨瓣压差与术后即刻测定值无显著差异。作者认为,PBPV应列为治疗单纯肺动脉瓣狭窄的首选方法。
Report of 11 patients with pulmonary valve stenosis percutaneous balloon pulmonary valvuloplasty (PBPV) treatment experience. The systolic pressure of right ventricle decreased from 75.5 ± 49.7 to 38.7 ± 13.8 mmHg before operation (P <0.01). The systolic pressure of pulmonary artery increased from 15.2 ± 6.5 to 21.0 ± 5.0 mmHg before operation (P <0.01). The mean pulmonary artery pressure increased from 8.5 ± 2.9 to 9.8 ± 3.6 mmHg preoperatively (P <0.05). The pulmonary valve pressure transvalue decreased from 60.1 ± 16.9 preoperatively to 33.5 ± 16.6 mmHg (P <0.01). After a year follow-up, transvalvular pressure and postoperative immediately after the determination of no significant difference. The authors believe that, PBPV should be classified as the preferred method of treatment of simple pulmonary valve stenosis.
