Surgical techniques for long-term studies of thoracic duct circulation in the rat

Abstract

Two techniques for cannulation of the thoracic duct in the rat, thoracic duct shunt and thoracic duct side fistula, are described. They give access, for repetitive sampling, to a normal thoracic duct circulation and are suited for study of the circulation under physiologic conditions. The thoracic duct shunt creates, with tubing, a shunt between the caudad and cephalad ends to the cisterna chyli. The exteriorized midportion of the shunt allows observation of the lymph. In the thoracic duct side fistula, the short arm of a T tube is placed within the cisterna and sampling is done via the long arm of the tube. Ten shunts functioned for 8-26 days and 10 side fistulas functioned for 8-30 days. Average lymph flow was 0.044 ml/min (shunts) and 0.042 ml/min (side fistulas). Average thoracic duct lymphocyte output was 1,729,000 cells/min (shunts) and 2,310,000 cells/min (side fistulas). Average blood lymphocyte count was 11,700 cells/mm3 (shunts) and 12,600 cells/mm3 (side fistulas). All parameters remained stable during the period of study. Advantages of those techniques over the Bollman end fistula are presented.
