Purpose : Superior vena cava (SVC) stenosis during follow-up is one of major concerns after heart transplantation. And many technical modifications were introduced. We analyzed the surgical results of SVC intima layer only suture technique in heart transplantation.
Methods : We underwent the SVC anastomosis with only intima layer during heart transplantation. We measured the area of SVC at 3 different points including above anastomosis, anastomosis, and below anastomosis in axial view by free drawing regions-of-interests (ROI) method and evaluated the degree of stenosis. Between June 2017 and May 2020, the patients who can check the cardiac computed tomography (CT) at postoperative 2 years were included in this study.
Results : We underwent heart transplantation in 41 patients. Among them, 24 (16 males and 8 females) patients can check the postoperative 2 years follow-up cardiac CT. Mean age at operation was 49.4 ± 4.9 years. The diagnosis at operation was dilated cardiomyopathy (n = 12), ischemic heart disease (n = 8), valvular heart disease (n = 2), hypertrophic cardiomyopathy (n = 1), and congenital heart disease (n = 1). There was no postoperative bleeding control case. Mean CT follow-up duration was 1.9 ± 0.7 years. The mean area at 3 points were 2.7 ± 0.8㎠, 2.7 ± 0.8 ㎠, and 2.7 ± 1.0 ㎠ (P = 0.996). And there was no SVC stenosis related symptom during follow-up.
Conclusion : SVC intima layer only suture technique is safe and effective method in heart transplantation.
