Abstract
From January 1986 to December 1990 we studied angiographically the subclavian-brachiocephalic vein of 100 patients dialysed by subdavian catheter for 50 (first group) and by internal jugular catheter forthe 50 others (second group). These two groups were not statistically different as regards age (61.6 ± 11.3 years in the first and 61 ± 11.1 in the second), sex (48% and 56% were women), duration of catheter insertion (31 ± 21.8 and 31.7 ± 16 days), andthe number of dialysis sessions (13.5 ± 9.1 and 13.6 ± 7.1). The type of catheters, the frequency of removal for poor flow (16% in both groups) or infections (6% in both groups), and localnursing were similar in the two groups. The only difference was the side of cannulation: the right side in 58%of cases in group 1 and 78% in group 2. The giographic study revealed a stenosis of the vein in 42% of the subdavian group and in 10% of the internal jugular group: a dramatic difference in favour of the internal jugular route, whose superiority over the subdavian route is asserted in respect of venous access ofdialysed patients
