[Closure of major aorto-pulmonary collateral artery with the Amplatzer vascular plug in an infant with pulmonary atresia and ventricular septal defect - a difficult therapeutic problem]. / Zamkniecie nieprawidlowego polaczenia aortalno-plucnego zatyczka Amplatzer vascular plug u dziecka z zarosnieta zastawka plucna i ubytkiem miedzykomorowym - trudny problem terapeutyczny.

A case of a 2-day-old newborn with congenital heart disease, pulmonary atresia and ventricular septal defect is described. The Blalock-Taussig shunt was created 6 days after birth. After the procedure, the newborn developed symptoms of increased pulmonary blood flow and respiratory distress. We decided to close one of the major aortopulmonary collateral arteries with the Gianturco coil on the 41st day after birth, however the results were not satisfactory. On the 66th day of infant life (by that time the patient weighted 3 kg), another procedure with the Amplatzer vascular plug was performed. This procedure was successful. After a few days the infant was discharged from hospital.

Application of the CardioCel bovine pericardial patch - a preliminary report.

INTRODUCTION: Animal pericardial patches are widely used in adult and pediatric cardiac surgery. A search is ongoing for a new material with optimal surgical properties that will reduce intraoperative bleeding and the occurrence of restenosis, calcification, and pseudoaneurysms in long-term observation. One product of interest is the CardioCel bovine pericardial patch. AIM: Evaluation of the short-term results of CardioCel bovine pericardial patch implantation during pediatric cardiac surgery. MATERIAL AND METHODS: The study included 8 patients who underwent surgical correction of congenital cardiac defects between January 2015 and February 2016. Pericardial patches were used to repair supravalvular aortic stenosis and reconstruct the aortic arch and pulmonary arteries. The age of the patients ranged from 10 days to 14 years. RESULTS: There were no hospital deaths. The new material exhibited satisfactory durability and elasticity during surgery, facilitating optimal adaptation of the patch to the patient's tissues. No significant bleeding was reported from the suture site. The median duration of follow-up was 58 days. During the follow-up, there were no symptoms of pseudoaneurysm formation, patch thickening, or calcification in the areas where the pericardial patches were implanted. No clinical or laboratory symptoms of infection were observed in locations where the new material was applied. CONCLUSIONS: Satisfactory surgical properties of the patch were observed intraoperatively. Positive results using the new pericardial patch were obtained in short-term follow-up.

Infection risk factors in pediatric cardiac surgery.

Cardiac operations were preformed in 499 children from January 1998 through December 1999. Their median age was 263 days. A positive culture from blood, bronchoalveolar lavage, wound, or central catheter was obtained in 110 patients (22%). Age, sex, presence of pulmonary hypertension, body surface area, ratio of body surface area to oxygenator surface area, whether heart surgery was open or closed, and the duration of the operation, cardiopulmonary bypass, intubation, and intensive care were analyzed. Patients who developed infections were significantly younger, with smaller body surface areas and disparity with the oxygenator surface area, longer operative and bypass times, extended intubation, and prolonged intensive care. There was a significant correlation between infection and pulmonary hypertension. Sex and type of operation were not predictors of infection.
