Table 3 Diagnosis of the patients with chylothorax

From: Chylothorax after surgery on congenital heart disease in newborns and infants -risk factors and efficacy of MCT-diet

  1. * chylothorax in HRHS in one patient occurred after a neonatal operation (reconstruction of the RVOT), in one patient after bidirectional Glenn procedureand in one patient after valvuloplasty at the age of five month. CVP after bidirectional Glenn operation was below 18 mm of mercury during ventilation.
  2. ** In HLHS two cases of chylothorax occurred during the Norwood I procedure, two cases of chylothorax occurred after the bidirectional Glenn anastomosis. CVP was regular (14 - 16 mmHg) after extubation in both patients.
  3. *** 9 out of 36 patients were bidirectional Glenn operations
  4. **** 12 out of 36 operations were bidirectional Glenn operations
  5. ***** 2 out of 4 patients with chylothorax after correction of AVSD were suffering on Down-syndrome; 6 out of 25 children without chylothorax after correction of AVSD were without Down syndrome.
  6. Most patients developed chylothorax after the correction of a transposition the great vessels. After HLHS and AVSD operations the chylothorax was seen as well. Abbr.: HRHS = hypoplastic right heart syndrome, HLHS = hypoplastic left heart syndrome, AVSD = atrium ventricular septal defect, VSD = ventricular septal defect, ASD = atrium septal defect, TAC = truncus arterious communis, TGA = transposition of the great vessels, DORV = double outlet right ventricle, TOF = Tetralogy of Fallot, CoA = coarctation of the aorta; ALVS = aorto left ventricular shunt
