Closure of residual leakage after the use of hybrid umbrella in umbrella technique: A case report

Özet

Patent ductus arterious (PDA) is a common congenitalheart defect. Some adults with PDA are often associated withsevere pulmonary hypertension and frequently have to forgotheir chance of surgery because the lung conditions progress toEisenmenger syndrome (1). Therefore, early treatment should beperformed as soon as a diagnosis of PDA is established. Severalmethods, including surgical ligation and transcatheter occlusion,have been currently employed for the treatment of PDA. However, surgical ligation has major disadvantages, such as significanttrauma and other complications associated with thoracotomy.Transcatheter occlusion must be carried out under fluoroscopyand angiography, which causes inevitable radiation injury. Furthermore, closure of a large-sized PDA defect is technically challenging and carries a risk of device embolization (2, 3).
