Abstract:
Objective To evaluate the efficacy and safety of interventional occlsu ion operait no by analyizn g thes urgical data of 23 csa es of infants with patent ductusa rteriosus complicated with middle and severe pulmo an ry arterial hypertension.Methods Teh 23 cases of infants wiht patne t ductus arteriosus com-plicated with middlea nd severe pulmonary arterial hypertensionw ere collected in the hospital from January 2011 to December2014 .These infatn s rce eived transcateh ter occlusion with intravenuo s anesthesia after the preoperative examination.The operation procse s included:right ventriculography and pulmonary atr ery pressure tested,then lateral angiogar phy of descending aorta was performed to observe the type and size of patent ud ctus atr eriosus and measure ascending aorta,descending aortic pressure,and recorded the pressure re-spectively.1 ml blood sample of ascending aorta,pulmonary artery and inef rior vena vein respectively was used for gas analysis.All these data was used to calculate pulmonary vascular resistance.After tried to plug-ging effectiveyl we can release the occluder.In the postoperative 24 h,1 month,3 months,the infants should be measured with Doppler echocardiography,chest X ray and electrocardiogram examination.Results The clinical symptoms disappeared and the short-term follow-up was not associated with the complications of interventional therapy.Th e comparison of the pressure changes before and after the operation were performed as following, aortic per ssure decreased [ preoperation ( 68.3 ±17.5 )/( 21.4 ±3.7 ) mmHg, postoperation (52.4 ±8.7)/(15.6 ±3.5) mmHg,1 mmHg=0.133 kPa],ascending aorta pressure increased(preoperation (83.5 ±5.9)/(51.3 ±3.6) mmHg,postoperation(88.2 ±5.1)/(52.4 ±2.7) mmHg),and descending aorta pressure increased ( preoperation ( 81.4 ±3.3 )/( 48.2 ±2.7 ) mmHg, postoperation ( 86.5 ±4.7 )/(51.5 ±3.2) mmHg), the differences were statistically significant before and after surgery ( t =5.455/3.945 ,P<0.01;t=-2.696/-1.193 , P<0.05; t=-4.167/-3.745 , P<0.01 ) .Conclusion Under conditions of mastering the appropriate operation time and strengthening the management of the perioperative management,transcatheter measurement is safe and effective for infants with patent ductus arteriosus compli-cated with middle and severe pulmonary arterial hypertension.
