Interventional treatment of anastomotic leakage after repair of complex congenital heart disease:4 cases report and literature review
Anastomotic leakage is a common complication after surgical repair of complex congenital heart disease(CHD).When the leakage is small,it may close spontaneously over time,in which case it may be treated conservatively or without treatment.When the leakage is large,it will cause hemodynamic disorder,and in severe cases,it can lead to heart failure or sudden death,requiring surgical intervention.In the past,reoperation was the main treatment for this type of anastomotic leakage.However,surgery often requires reoperation,cardiopulmonary bypass,and general anesthesia,which not only causes great trauma and high risk,but also increases the difficulty of reoperation due to the adhesion of pericardium and surrounding tissues after the first operation.In recent years,with the development of interventional technology for CHD,interventional therapy has gradually become an ideal alternative to secondary surgery due to its advantages of minimally invasive,exact effect,good repeatability and few complications.At present,there are few clinical cases of interventional treatment of anastomotic leakage after surgical repair of complex CHD.This paper reported four cases of successful interventional closure of anastomotic leakage after surgical repair of complex CHD and systematically reviewed the relevant literature,in order to provide new ideas for clinical treatment of this disease.
