[Duplex ultrasound measurement of morphologic parameters before and following repeated puncture of the femoral artery for intermittent infusion therapy].

In order to estimate morphologic changes of the femoral artery after an intermittent intraarterial infusion therapy duplex scanning was performed before therapy, immediately after a series of 26 (10 to 52) infusions, and 30 weeks after hospital discharge. Minimum and maximum values of internal and external vessel diameter and thickness of wall were estimated in the common femoral artery, superficial femoral artery, and deep femoral artery. The external diameter values and the thickness of wall increased significantly after therapy. After 30 weeks these values decreased but did not reach the initial values.
