A case of bacteremia and disseminated intravascular coagulation after the conduit procedure for tetralogy of Fallot with pulmonary atresia.

A case undergoing conduit procedure for tetralogy of Fallot with pulmonary atresia was complicated postoperatively by bacteremia due to non-fermentative Gram-negative rods and by disseminated intravascular coagulation. He was able to be cured without any sequela. The patient was a 16-year-old male, who had undergone Blalock-Taussig anastomosis in his infancy. The present operation was carried out as follows: ventricular septal defect was closed with a Teflon-patch and discontinuity between the right ventricle and the pulmonary artery was corrected using a Hancock's valved conduit. Two weeks after the operation, pleural effusion in the right chest cavity was shown by a chest X-ray film. On the 32nd postoperative day, high fever with chills occurred, and subsequently developed pulmonary edema, shock and hemorrhagic tendencies with petechia. Pseudomonas aeruginosa, Flavobacterium and Alcaligenes faecalis were detected by the culture of pleural effusion. The platelet count decreased to about 10,000/microliters. Carbenicillin, tobramycin and minocycline were administered for the infection, and heparin and aprotinin were used for disseminated intravascular coagulation. By these treatments for about 6 months, the patient became well and was discharged without any sequela.
