RESUMO
A large left-sided pleural effusion occurred in a 12-year-old end-stage renal disease patient undergoing chronic hemodialysis (HD). The fluid had physical and laboratory characteristics of chylothorax (CHTX) and was probably related to the multiple HD accesses placed in the neck area. Initially, thoracenteses were performed and the fluid discarded. Subsequently, a permanent drainage catheter placed in the left hemithorax was connected to a syringe with a stopcock, and from here to the arterial port of the HD catheter. One liter of CHTX fluid was removed on dialysis days three times weekly, for 7.5 weeks, and directly re-infused into the patient in a closed sterile circuit. A total of about 20 l was safely returned to the patient. The procedure was well tolerated and provided time until the CHTX resolved spontaneously. It is recommended that in similar clinical settings re-infusion of CHTX fluid should be performed to prevent the loss of protein-/T-cell-rich fluid.
