Arterial abnormalities in talipes equinovarus as assessed by angiography and the Doppler technique.
Preoperative angiography in 30 uncorrected clubfeet demonstrated abnormal vascular patterns in all but two limbs with hypoplasia or premature termination of the anterior tibial and medial plantar arteries in the remainder. Postoperative Doppler studies in nine of the limbs with abnormal vessels indicated that these arteries were present. We suggest that the continuous-wave Doppler technique is less useful for identifying major arteries than either dissection or angiography. Furthermore, arterial dysgenesis may play a role in the etiology of clubfoot. Since the posterior tibial artery usually provides the sole arterial supply to the foot, this vessel must be preserved at surgery and during subsequent ankle dorsiflexion.
