Summary:
Background. Arterial ischemic disease represents highly serious complication for patients undergoing chronic
haemodialysis. The aim of the study was to examine peripheral arteries in the group of haemodialysed patients and
to estimate the incidence and seriousness of pathological findings.
Methods and Results. Total 82 sonographic examinations of arteries in lower extremities using Multi Dopplex
II set with graphic registration of dopplex curves was done in 53 dialysed patients. Blood pressure values of four
peripheral arteries at legs together with blood pressure values at the brachial artery were evaluated as the ankle-arm
index (API). Character of changes of dopplex curves was classified as SO index (obliteration index). Also with
normal API, changes in SO were identified. SO index was significantly higher (p=0.034) in patients of the peritoneal
dialysis program in comparison with haemodialysed patients, in persons with diabetes the value was only marginally
higher. Patients who died later (of the cardiovascular complications), the SO index was significantly higher then in
others (p<0.0001), though the API values were not different. Repeated testing in 29 patients after 6 months brought
about worsening of the SO index (p<0.00001) in those patients where no changes of API were seen. No relation with
any of the followed biochemical parameters was found.
Conclusions. To estimate most accurately the conditions of the peripheral arteries in dialysed patients ankle-arm
index was used together with evaluation of the shape of dopplex curves (index SO). Such detailed Doppler
examination has proved identifiable changes of arteries in 73 out of 82 cases.
