Use of Amplatzer duct occluder to close severely hypertensive ducts: utility of transient balloon occlusion.

摘要: BACKGROUND The dividing line between a patent ductus arteriosus with severe but reversible pulmonary artery hypertension and an Eisenmenger duct remains elusive. Increasing experience the Amplatzer occluder has made non-surgical closure of even large simple safe. However, data on use this device in severly hypertensive ducti is sparse. METHODS AND RESULTS There were six patients (2 males, 4 females), wherein transient ductal occlusion was done embolectomy balloon catheter. post-occlusion hemodynamics along overall clinical hemodynamic assessment used to decide likelihood benefit choice device. In four (pulmonary vascular resistance index> 8.0 U/m2) successfully closed using occluder, while two ventricular septal defect used. CONCLUSIONS Transient quite helpful for assessing hypertension, short-term non-invasive follow-up shown strategy be safe useful.
