[Initial experiences with PTA of hemodialysis shunts]

Our experience of using PTA for stenoses of haemodialysis fistulae in 11 cases is described. PTA is the procedure of choice for re-establishing adequate shunt function. Intraluminal pressure measurements on the venous limb of well functioning Cimino shunts produced values of 7.5 to 44.5 mmHg, average 24.5 mmHg. These values are the basis for judging the success of a dilatation. Shunt angiography with DSA with a highly diluted non-ionic contrast medium injected via a remaining dialysis needle is an effective procedure with minimal discomfort to the patient.
