ABSTRACT

There are still differences in the surgical treatment of children with pulmonary atresia(PA-VSD) with ventricular septal defect. The high rate of postoperative complications and reoperation intervention is still a problem that plagues surgeons. There are few reports on the understanding of the anatomy and physiological functions of MAPCAs. This article systematically reviews and analyzes domestic and foreign literature, and reviews the anatomical classification, surgical management strategies and related complications of PA-VSD patients.

ABSTRACT

Objective:To investigate the clinical outcomes of selective major aortopulmonary collaterals(MAPCAs) unifocalization and report histopathological findings in patients with pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals(PA/VSD/ MAPCAs).Methods:The study enrolled 6 MAPCAs/VSD/PA patients with age ranged from 6 to 96 months and body weight ranged from 5.0 to 23.0 kg. These patients underwent selective MAPCAs unifocalization and primary repairs. Preoperative cardiac catheter, selective arteriography, cardiac CTA and intraoperative pathology were performed to identify different function, anatomic distribution and histopathology of MAPCAs.Results:6 MAPCAs/VSD/PA patients underwent selective MAPCAs unifocalization and primary repair. No death occurred after operation and at follow-up which lasted for 1 to 20 months. Preoperative cardiac catheter, selective arteriography and intraoperative histopathology demonstrated distribution of functional MAPCAs similar to native pulmonary artery arborization and participating in arterial gas exchange. Functional MAPCAs were classified into elastic arteries according to histopathology.Conclusion:There are two histological type of MAPCAs which play different roles. Selective unifocalization to functional MAPCAs which are classified into elastic arteries like native pulmonary artery is a safe and effective treatment approach for PA/VSD/MAPCAs.

ABSTRACT

Objective To analyze the clinical characteristics of complete transposition of great arterial with left ventricular outflow tract obstruction(TGA/LVOTO) patients who received arterial switch operation(ASO),and further evaluated the risk factors of postoperative adverse events.Methods Retrospectively evaluated the adverse events(including postoperative mortality,reoperation,aortic valve insufficiency,re-LVOTO and mitral valve insufficiency) and the related risk factors of 39 TGA/LVOTO patients after ASO.Results 39 TGA/LVOTO patients were included,the mean Z value of PV was 0.6,the mean peak LVOT gradient was 31.6 mmHg (1 mmHg =0.133 kPa).The mean follow up time was 15.9 months,during the follow up,1 patient had early mortality,and CPB time(P =0.034) was associated with early mortality;4 patients had early reintervention;15 patients had AVI,and larger PV Z value(P =0.026) was associated with postoperative AVI;7 patients had MVI,and subvalvar level LVOTO(P =0.001) was associated postoperative MVI;6 patients had re-LVOTO,and older age at operation (P =0.029),muhi-level LVOTO (P =0.024) were associated with postoperative re-LVOTO.Conclusion If the obstruction of LVOT can be repaired by surgery,TGA/LVOTO patients had a satisfied prognosis after ASO with relief of LVOTO,the postoperative early mortality was very low,and although the probability of re-LVOTO was increased with time,the long-term reintervention probability was very low.
