Abstract
1. Anatomical snuffbox arterio-venous fistula was established in 73 patients who had been newly placed on hemodialysis, and the post-operative course was analyzed for 34 months. Fifteen shunts were obstructed (21%). Early (within twelve weeks following operation) and late obstruction were observed exclusively in patients with diabetic nephropathy.
2. The blood flow wave pattern was recorded by the supersonic Doppler method. The change in blood flow with tabaciére shunt was studied for one week after the operation. The average amount of blood flow was about 200ml/min, which was judged to be satisfactory for hemodialysis patients with diabetic nephropathy. No special wave pattern, however, was observed in patients with diabetic nephropathy.
