In group A, side by side, double-lumen, Polyurethane catheters were applied to five dogs with either sexes(3 male and 2 female) weighing 11.5 -23 kg in the periods of 7 to 21 days external jugular vein as the vascular access of hemodialysis. Vascular thrombosis was prevented by 1.3 ml of heparin (5,000 IU/ml)flushing and by oral aspirin 10 mg/kg B.W. Once daily. Hemodialysis was the removal of catheters. Complications are described as following: severe hemorrhage at the puncture site in one case, local inflammation at the catheter entry site in 5 cases, catheter withdrawn by the dog in 2 cases, severe hematoma in 2 cases, and inadequate blood flow in 3 cases. Venous stenosis was observed in 4 cases on autopsy. In group B, unreserved teflon single lumen catheters were placed bilaterally to 6 dogs of either sex ( 3 male and 3 female) weighing 12-22kg, which were removed after each hemodia- lysis. In 19 cases, vein stenosis developed in 5 catheterization , hematoma was noted in 2 cases, and the catheter was withdrawn by one dog. In conclusion, infection and thrombosis has been the major drawbacks of hemodialysis catheterization, and repeated catheterization should be avoid for the high occurance of venous stenosis.
