Pulsed color-flow Doppler analysis of arterial deficiency in idiopathic clubfoot.
This prospective study used pulsed color-flow Doppler sonography to determine differences in the presence and direction of flow through the dorsalis pedis, posterior tibial, and peroneal arteries in a group of children with clubfoot and a comparison group of controls. There was a statistically significant difference in the prevalence of deficient (absent or retrograde flow) dorsalis pedis arteries in children with clubfoot (45%) compared with controls (8%). This indicates that there is an association between some clubfeet and deficiency of the dorsalis pedis artery. There was a trend toward difference in the prevalence of deficiency of the dorsalis pedis artery in the clubfeet that required surgery (54%) compared with those that did not (20%), suggesting that dorsalis pedis artery deficiency may be more prevalent among clubfeet with greater deformity.
