SUMMARY OBJECTIVE: Fluid overload is associated with increased mortality and morbidity in pediatric cardiac surgery. In the pediatric age group, peritoneal dialysis might improve postoperative outcome with avoiding fluid overload and electrolyte imbalance. It preserves hemodynamic status with the advantage of passive drainage. In this study, we are reporting our results of peritoneal dialysis after cardiac surgery. METHODS: In this retrospective study, we evaluated the patients who underwent pediatric cardiac surgery in our hospital between December 2010 and January 2020. Patients who required peritoneal dialysis during hospitalization period were included in the study. Patients’ clinical status and outcomes were evaluated. RESULTS: Peritoneal dialysis was performed to 89 patients during the study period. The age varies from the newborn to 4 years old. The indication of peritoneal dialysis was prophylactic in 68.5% (n=61) and for the treatment in 31.5% (n=28). There were 31 mortalities. The risk factors for the mortality were preoperative lower age, longer cardiopulmonary bypass time, lengthened intubation, lengthened inotropic support, and requirement of extracorporeal membrane oxygenation (p<0.0001). CONCLUSION: Earlier initiation of peritoneal dialysis in pediatric cardiac surgery helps maintain hemodynamic instability by avoiding fluid overload, considering the difficulty in the treatment of electrolyte imbalance and diuresis.

SUMMARY OBJECTIVE: In deep venous valve repair, transcommissural external valvuloplasty (TEV) is the commonly used technique. In some cases, external banding (EB) is combined with this procedure to improve the patency and durability of the surgical procedure. METHODS: We retrospectively analyzed patients who underwent deep venous valve repair from 1998 through 2018. Patients were divided according to the surgical procedure: Group A: TEV alone and Group B: TEV+EB. Early postoperative outcomes of the procedure were compared between the groups. RESULTS: There were 265 patients in Group A and 165 patients in Group B. The mean follow-up period was 4.2±3.7. The rate of recurrence of venous reflux, ulcer, and reoperation were 31.9 versus 30.9, 21.2 versus 21.8, and 16.7 versus 13.9 in Group A and Group B, respectively. There were 67 reoperations in the follow-up period. At reoperation, external valvuloplasty was performed in 64% of the reoperations in Group A, while this rate was 13% for Group B. CONCLUSIONS: There is no more need for EB during the venous valve repair with the increased experience of valvuloplasty techniques. TEV might be enough with acceptable long-term outcomes during deep venous reconstruction.
