[Pre-transplantation evaluation with echo-Doppler of the receptor's vascular risk factors].
A total of 51 potential recipients of a renal transplant (RT) have been evaluated with an Eco-Doppler study of the posterior femoral, popliteal and posterior tibial corteries. Acceleration (AC), mean rate (MR), maximum systolic rate (MXSR) and minimal diastolic rate (MNDR), as well as pulsatility (PI) and resistance index (RI) were measured. Arterial high blood pressure (HBP), smoking, time in haemodialysis (HD) and cholesterol and triglycerides levels, were evaluated as vascular risk factors. RI and PI were maximal, and MXSR, MR and AC minimal at the popliteal artery level. Smoking (number of cigarettes/day) (R = 0.77), systolic blood pressure (BP) (R = 0.43), time of HBP evolution (R = 0.044), cholesterol level (R = 0.43) and time in HD (R = 0.35) correlate with Eco-Doppler parameters. Fifteen of these 51 patients underwent transplantation, and increased RR and PR with decreased MR and MXSR were seen post-RT in the ipsilateral popliteal and posterior tibial arteries. Eco-Doppler is a useful technique to evaluate the vascular risk of potential RT recipients.
