RESUMO
SUMMARY OBJECTIVE: This study aimed to compare the effectiveness of resection and extended end-to-end anastomosis between neonate and infant patients with coarctation. METHODS: This study was designed retrospectively and included 41 neonate (<30 days) and infant (30 days to 1 year) patients who were operated on using the resection and extended end-to-end anastomosis technique for aortic coarctation. Preoperative aortic annulus diameters and Z scores, all aortic arch diameters and Z scores, the presence of hypoplastic aortic segment, and the presence of prematurity were reviewed in both groups. Subsequently, we investigated whether these parameters were statistically related to the residual gradient in the operation area, whether there was a need for early re-intervention, and what was the incidence of mortality in the early postoperative period. In addition, the aortic arch Z scores of the patients at 6 months postoperatively were examined. RESULTS: While the mean age (p<0.001), body weight (p<0.001), and proximal arch Z score (p=0.029) were found to be significantly lower in the neonate group than in the infant group, the total length of the intensive care unit stay (p=0.013) and the total length of hospital stay (p=0.017) were found to be significantly higher. In addition, significant enlargement was detected in the proximal arch, distal arch, and isthmus segments in both patient groups. CONCLUSION: The resection and extended end-to-end anastomosis is an equally effective technique that can provide a marked decrease in gradient in the coarctation area and a significant enlargement of the aortic arch segments in the early period after coarctation repair in both neonate and infant patients.
RESUMO
ABSTRACT Introduction: Cyanotic congenital heart diseases constitute 40-45% of all congenital heart diseases. In patients who are not suitable for primary repair, modified BT (MBT) shunt and central shunt (CS) procedures are still frequently used. Methods: This study included 62 pediatric patients who underwent MBT shunt or CS via median sternotomy. Patients' demographic, echocardiographic, operative, and postoperative data were collected retrospectively. The patients were classified as single ventricle and bi-ventricle according to their cardiac anatomy, and the presence of prematurity and heterotaxy was noted. Procedure details of the patients who underwent endovascular intervention prior to the surgery were investigated, and operation data were accessed from the surgery notes. Data regarding postoperative follow-ups were obtained and comparatively analyzed. Results: Of the total 62 patients, 32 (51.6%) were newborns and 16 (25.8%) had a body weight < 3 kg. MBT shunt was applied to 48 patients (77.4%), while CS was applied to 14 patients (22.6%). There was no significant difference between the two surgical procedures in terms of requirement for urgent shunt or cardiopulmonary bypass, additional simultaneous surgical intervention, need for high postoperative inotropes, and in-hospital mortality (P>0.05). The rate of congestive heart failure in patients with in-hospital mortality was determined as 66.7% and it was significantly higher than in patients without heart failure (P<0.001). Conclusion: MBT shunt and CS are still frequently used in cyanotic patients. The use of small-diameter shunts, particularly when centrally located, can prevent the onset of congestive heart failure and lower mortality.
RESUMO
ABSTRACT The presence of persistent left superior vena cava to the left atrium connection without an innominate vein may give rise to technical challenges during intracardiac repair. In this report, the end-to-side anastomosis technique of the persistent left superior vena cava to the right superior vena cava is discussed in a patient with tetralogy of Fallot associated with persistent left superior vena cava draining directly into the left atrium. A successful end-to-side anastomosis between the persistent left superior vena cava and the right superior vena cava was performed and short-term anastomosis patency was documented via angiography.
