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.
对30例未经矫正的马蹄内翻足进行术前血管造影显示，除两例肢体血管发育不全或其余肢体胫前动脉和足底内侧动脉发育不全或过早终止外，其余均有异常血管模式。对9例血管异常的肢体进行术后多普勒研究表明这些动脉是存在的。我们认为，与解剖或血管造影相比，连续波多普勒技术在识别主要动脉方面用处较小。此外，动脉发育异常可能在马蹄内翻足的病因中起作用。由于胫后动脉通常是足部唯一的动脉供应，因此在手术及随后的踝关节背屈过程中必须保留该血管。
