Revision of the incidence of congenital absence of dorsalis pedis artery by an ultrasonic technique

Abstract

Ultrasound studies of dorsalis pedis artery in 400 feet showed the artery to be absent in 2.25%, i.e., much less frequently than it was commonly claimed. Clearer understanding of this variation and its frequency may facilitate the diagnosis of peripheral circulatory disease.

The medial malleolar network: A constant vascular base of the distally based saphenous neurocutaneous island flap

“…The vascular axes of the two saphenous nerve branches and their anastomoses with the medial malleolar network are not shown (AT, tibialis anterior m.; PT, tibialis posterior m.; other abbreviations are listed in table 1 ); d Final result after uneventful postoperative course the transverse bimalleolar axis, are in agreement with the literature [15,22,37]. In none of our specimens was the dorsal pedis a. totally absent, in contrast to s o m e p u b l i s h e d d a t a i n d i c a t i n g the "absence" of the dorsal pedis a. in 2.25% and 14.2% of specimens [10,15,22,23,27,28,31]. However, a close analysis of the literature reveals that in those series with the highest incidences of "absence" not only absent but also small arteries were excluded [15,27,37].…”

Turner syndrome – an accidental finding?

“…The absence of pedal pulses is, however, valueless in the diagnosis of Turner syndrome, as the degree of severity of aortic coarctation cannot be correlated with presence of lower extremity pulses, which result from variation in collateral blood supply, unless corroborated by other physical signs. 5 Despite specific physical findings of short stature in the presence or absence of lymphoedema and web neck, the diagnosis of Turner syndrome is, however, often delayed in many affected girls, as in this case. 1,3 This is because, although these clinical findings are frequent in patients with Turner syndrome, they occur relatively infrequently in the general population.…”

The dorsal pedis artery as a new distal landmark for extramedullary tibial alignment in total knee arthroplasty

“…We usually wrap around the entire leg with an adhesive transparent drape in order to clearly identify distal landmarks including the dorsal pedis artery, the malleolar centre, and the extensor hallucis longus tendon. If the pulse of the dorsal pedis artery is impalpable, congenital absence [3] should also be taken into account. Yamada et al [20] reported the prevalence of congenital absence on the dorsal pedis artery was 6.7 % in the cadavers.…”
