Congenital arterial malformations associated with clubfoot. A report of two cases.

Arteriograms were examined in three limbs of two patients who had talipes equinovarus. An abnormal arterial pattern characterized by severe diminution in the size of the anterior tibial artery and diminution or absence of the dorsalis pedis artery was evident. Inasmuch as one of these patients was preambulatory, the arterial malformation is congenital and would not have been acquired in walking. The relationship between the abnormal arterial and bony pattern in talipes equinovarus is comparable to that previously described for congenital absence of the fibula. A possible etiologic relationship between TEV and embryonic arterial accidents is suggested.
