Prospective evaluation of lower limb arterial blood flow velocity and vascular complications of percutaneous transfemoral arterial catherterization was carriedout in 26 children at S.N.U.H. Children's hospital from Dec. 1985 to May 1986. Common femoral and popliteal arterial velocity singnals of both limbs were monitored and compared by doppler duplex sonography immediately after angiography and at 24-48 hours later. In most cases, the average velocity of proximal femoral artry and popliteal artery of puncture site was slower than that of the other limb vesels. In complication group of thromboembolism, the catheterization time was longer, the catheter size was larger, the velocity discrepancy of both limb arteries was larger, the doppler velocity profile was more irregular, and the diurnal change of arterial velocity discrepancy was slower than in normal control group. It is recommended that the catheterization time is less than 30 minutes and the catheter diameter is less tha two-fifths of the femoral arterial diameter. Systemic heparinization within 24 hours is required if the catheterization time is longer of blood flow disturbance is detected on doppler examination. The doppler duplex sonography is a simple, rapid, and noninvasive technique for assesing lower limb hemodynamis, especially in patients undergoing transfemoral arterial catherization.
