[The changes in lymphocytes subpopulations of a patient with postoperative chylothorax].
A case of 64-year-old male who developed chylorrhea at 2 days post coronary artery by-pass grafting, is reported. He was managed conservatively for 3 weeks. But chylothorax was not improved, he was treated operatively. Analysis of his lymphocyte subpopulations in peripheral blood were performed during the course of chylothorax. Lymphocytepenia became apparent and subpopulation of T cell were decreased gradually. The subpopulation of CD 4(+) cell decreased, while the subpopulation of CD 8(+) increased. The CD 4(+) cell/CD 8(+) cell ratio decreased consequently till 7th day after 2nd operation. Although the replenishment of nutritional deficiencies using TPN allows prolonged conservative management for chylothorax patient, the deterioration in cellular immunocompetence can not be prevented at present. It is necessary to take great care about infection for chylothorax patient.
