Abstract:
The dorsalis pedis artery (DPA) is the primary source of arterial blood supply to the dorsum of the foot, serving as a key landmark for peripheral pulse evaluations, microvascular micro-surgical flaps, and distal arterial cannulations. This study utilized high-resolution color Doppler ultrasonography to comprehensively map the course, diameter variations, and terminal branching patterns of the DPA relative to bony soft-tissue axes. One hundred limbs from fifty healthy adult volunteers (25 males, 25 females; mean age 24.5 ± 3.2 years) were scanned using a 12-MHz linear array transducer. The classic linear continuation of the anterior tibial artery across the midpoint of the bimalleolar line was observed in 81.0% of limbs (n = 81). Variational configurations were documented in 19.0% of the cases. The most frequent variant involved a lateral deviation of the main DPA trunk toward the second intermetatarsal space (11.0%). Complete absence or severe hypoplasia of the DPA, where the dorsum of the foot was supplied by the perforating branch of the peroneal artery, was identified in 5.0% of limbs. The mean diameter of the DPA trunk at the ankle joint level was 2.14 ± 0.28 mm in males and 1.82 ± 0.21 mm in females (p < 0.05). These ultrasonic measurements offer specific anatomical margins, providing critical guidance for clinicians executing foot reconstructive flap adjustments or catheterization entries.
