Study about Branching Pattern of Dorsalis Pedis Artery with Clinical Significance | Chapter 3 | Emerging Trends in Disease and Health Research Vol. 8

The study's objective was to identify changes in the dorsalis pedis artery's origin, course, and branching structure. In order to diagnose peripheral arterial diseases of the lower extremities, such as thromboangiitis obliterans (TAO) or Buerger's disease, pulsations of the dorsalis pedis artery are routinely employed. The anterior tibial artery continues directly into the dorsalis pedis artery, which supplies blood to the dorsum of the foot. However, there are many vascular alterations in the lower limbs as a result of the numerous distal anastomoses surrounding the ankle joint. Given that it might be replaced by an enlarged perforating branch of the peroneal artery, the lack of a dorsalis pedis arterial pulse does not automatically indicate peripheral arterial disease. which might be narrow and deviate laterally on the dorsum of the foot, be absent, or both. We discovered uncommon changes in the dorsalis pedis artery's origin, course, and branching pattern during normal dissection of lower limbs for undergraduates. The second, third, and fourth dorsal metatarsal arteries in the current investigation were shown to originate from the dorsalis pedis artery rather than the lateral tarsal artery in the absence of the arcuate artery. 27 limbs had normal anatomical descriptions. We found variants in 13 specimens, including bilaterally anomalous origins for the dorsalis pedis artery, bilateral lateral deviations for the dorsalis pedis artery, twin dorsalis pedis arteries, trifurcation for the dorsalis pedis arteries, and lack of the arcuate artery. In order to reduce risks during surgical intervention, it is crucial to have a preoperative angiogram for any anomaly because variation in the dorsalis pedis artery is relatively prevalent.
