Anatomical study of Dorsalis pedis Artery and Its Clinical Correlations
2011
INTRODUCTION To evaluate patients with arterial disease, palpation of peripheral arterial pulse is commonly used. In lower limb, palpation of dorsalis pedis artery is used to evaluate the arteriosclerotic diseases. Dorsalis pedis artery is the main source of blood supply to the foot. A knowledge about the origin, course and branching pattern of this artery is essential, as it forms the stem for one of the major myocutaneous flaps, used for ankle surgeries in plastic and reconstructive surgeries. Fifty free lower limbs were dissected and the origin, course and branching pattern of dorsalis pedis artery were studied. 50 free lower limbs were collected from the anatomy dissection hall. The dorsalis pedis artery was dissected and its origin, course and branching pattern were studied. In the present study dorsalis pedis artery was found to have a normal course and branching pattern in 56%, variation in origin in 8%, variation in branching pattern in 16%, absence of the artery in 2% and d...
Relationship of the dorsalis pedis artery to the tarsal navicular
The Journal of foot and ankle surgery : official publication of the American College of Foot and Ankle Surgeons
When undertaking surgical maneuvers about the midfoot, caution must be used to avoid injury to the dorsalis pedis artery, which courses along the dorsum of the foot on the dorsolateral aspect of the tarsal navicular. In an effort to better understand the relationship of the course of the dorsalis pedis artery relative to the tarsal navicular, 128 embalmed feet (31 [48.4%] female and 33 [51.6%] male cadavers aged 15 to 91 years) were measured. The dorsalis pedis artery was dissected from its origin to its termination (i.e., the first dorsal metatarsal artery and the deep plantar perforating artery), and the distance from the medial cortex of the navicular tuberosity to the medial margin of the artery and the location of the artery as a percentage of the medial-to-lateral width of the navicular were measured. In the male cadaver specimens, the distance from the navicular tuberosity to the dorsalis pedis was 23.75 ± 3.1 mm, the width of the navicular was 37.41 ± 5.0 mm, and the locatio...
Anatomical Variations of the Dorsalis Pedis Artery in a Thai Population
International Journal of Morphology, 2022
The dorsalis pedis artery (DPA) is a vital artery that supplies the foot and ankle area which is clinically important for palpating when taking the pulse. This research was performed on fresh cadaveric dissection of 40 legs by injecting paint into popliteal artery for tracking the dorsalis pedis artery and its branches. The present research revealed that the Thai population has an anatomical variation and different location of the DPA and exact location of DPA for estimating the location of the DPA and may have clinical implications. The statistically descriptive analysis elucidated the distances of the DPA to the lateral malleolus and medial malleolus which were 51.48 ± 7.27 mm and 42.62 ± 11.40 mm, respectively. The distance of the extensor hallucis longus (EHL) to the DPA was 14.29 ± 4.11 mm. The length of the dorsalis pedis artery which measured from artery on intermalleolar line to its dipping in 1st intermetatarsal space to be 122.03 ± 21.07 mm. The arcuate loop which is anastomosis U-loop of lateral tarsal arteries of the DPA was found 55 % in Thais population. There were no statistically significant differences of all parameters between the side and sex in DPA consideration. An understanding of the variations of the anatomical vasculature of DPA is essential for precise clinical assessment because exact anatomical knowledge and location can contribute to the pulse taking and be applied in surgical procedure.
Anatomy of the Dorsalis Pedis Artery
The dorsalis pedis artery (DPA) is the largest blood vessel distal to the ankle joint. It is the continuation of the anterior tibial artery (ATA) and runs along the dorsum of the foot until the 1st intermetatarsal space. The DPA gives rise to five branches, viz. medial tarsal, lateral tarsal, arcuate, deep plantar and dorsal metatarsal arteries. Given the vast blood supply provided by the DPA, in the current era of microvascular surgery, the anatomy of the DPA is of increasing interest to anatomists, surgeons and angiographers. The aim of this study was to outline the course, origin, branching patterns and possible variations of the DPA. The present study included the dissection of forty (n=40) cadaveric specimens of the lower limb region (Left: 25; Right: 15). The origin, course and branching patterns of the artery were studied. These morphological parameters were further analysed with regard to laterality to determine if a correlation existed. The Pearson Chi-square test was employed and a p value of less than 0.05 was deemed statistically significant. Although the DPA was present in 97.5 % of cases, it followed the standard anatomical description in only 42.5 % of cases. The DPA originated from the peroneal artery in 5 % of cases. In 25 % of cases, DPA deviated laterally. Variation in the branching pattern of the DPA, which was recorded in 50 % of cases, was further classified according Types 1 to 6. The findings of this study correlated closely with most previous studies. However, the incidence of lateral deviation of the DPA was higher in this study as well as the incidence of Type 1 variation in branching pattern. Additionally, this study proposes a novel variation in branching pattern which has been termed Type 6, which displays a recurrent branch of the Type 5 variation. The DPA has an important role in a clinical setting since the DPA flap is employed in reconstructive surgeries and peripheral circulation may be assessed by the palpation of the DPA pulse. Therefore, a thorough understanding of the anatomy of the DPA is of prime importance to podiatrists, surgeons, anatomists and angiographers.
Anatomical variation of the Dorsalis pedis artery in a South African population – A Cadaveric Study
The Foot, 2018
Background: The dorsalis pedis artery is responsible for blood supply to the dorsal aspect of the foot and is vital in the clinical assessment of the arterial supply thereof. Clinical assessment should consider anatomical variations of dorsalis pedis artery. Clearly, a thorough understanding of the potential variations of the vasculature in the area is important for a precise clinical assessment of arterial supply to the foot. The aim of this study was to investigate the different branching patterns of the dorsalis pedis artery that exist in a South African population. Methods: A Cadaveric study in which a total of 33 dissected lower limbs (27 adult cadavers and 6 partial wet lower limb specimens) of a South African population sample were studied. The course and branching pattern of the dorsalis pedis artery were photographed and documented. Results: Nine variations of the dorsalis pedis artery were recorded, with the standard branching pattern being the most common with an incidence of 36.36% and a completely absent dorsalis pedis artery variation was noted in 6.06% of the sample. Conclusion: Nine variations of the arterial anatomy of the dorsalis pedis artery were identified in this current study. Each of these may possibly alter the location or strength of the dorsalis pedis pulse affecting clinical assessment outcomes. Knowledge of dorsalis pedis variations may be useful to clinicians when making clinical decisions.

Detailed knowledge of the dorsalis pedis artery (DPA) on the dorsum of the foot is required for reconstructive surgery, especially when a dorsalis pedis flap is utilised. The aim of this study was to determine the size and branching pattern of the DPA. Within the anterior tarsal tunnel of 40 cadaveric ankles, the size and branches of the DPA were measured, while the relationship of the branches of the DPA to the inferior extensor retinaculum (IER) was noted. The thickness and the locations of the DPA and its branches provided statistically significant data (p>0.05) that the DPA does not divide into equal diameter branches at the level of the ankle joint. The branching pattern of the DPA can be divided into three categories: 27.5% of the arteries arise proximal to the IER, 62.5% of the branches deep to the IER and 10% of the terminal branches distal to the IER. The measurements and locations of the branches noted should assist and inform surgeons of variations

Accurate knowledge of the pelvic arterial anatomy is a prerequisite for the success and safety of the surgical and endovascular procedures performed in the male pelvis. Digital subtraction angiography (DSA) is the reference modality for the depiction of the branches of the internal iliac artery (which primarily supply the viscera and walls of the lesser pelvis) and the first step of all the relevant endovascular interventions (most commonly in the form of transarterial embolization). Identification of some of these branches during angiography is often challenging, because of their small size, complex course, superposition of other arteries and anatomic variants. This is a pictorial review of the basic DSA findings relevant to the male pelvic arterial anatomy. The angiographic technique is briefly described and a current practical approach that facilitates the angiographic identification of the branches of the internal iliac artery is also reviewed.

During routine dissection, we came across multiple variations in the dorsum of the right foot. Dorsalis pedis artery (DPA) presented with an unusual branching pattern. The arcuate artery was completely absent, and hence three tarsal branches arose from lateral side of DPA. The first branch continued as first dorsal metatarsal artery, the second branch continued as the second dorsal metatarsal artery, and the third branch continued as third dorsal metatarsal artery which also provided a small twig to the fourth intermetatarsal space as the fourth dorsal metatarsal artery. We also observed the unique presence of extensor hallucis brevis muscle with the origin from the medial part of superior surface of the calcaneus and inserted to proximal phalanx of great toe. Since the DPA was just beneath this muscle, anomalous presence of the muscle may lead to compression of DPA. Awareness regarding such variations is critical for angiographers, vascular surgeons, reconstructive and plastic surgeons.
Anatomic Study of Blood Supply of the Dorsum of the Foot and Ankle
Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2006
This project was to study the different patterns of the anterior tibal and dorsalis pedis arteries in relation to the blood supply of the dorsum of the foot and ankle. Methods: A reliable sample of 150 human embalmed cadavers was dissected. Results: Four different patterns were identified. The dorsalis pedis artery was most frequently (287 cases, 95.7%) found to be the continuation of the anterior tibial artery distal to the ankle, and lay between the tendon of extensor hallucis and the first tendon of extensor digitorum longus. The other 13 cases (4.3%) showed 3 variant patterns of the anterior tibial-dorsalis pedis vascular axis: the anterior tibial artery took a more lateral course, passing in front of the lateral malleolus (6 cases, 2%); the perforating branch of the peroneal artery assumed the expected course of the dorsalis pedis artery (4 cases, 1.3%); the anterior tibal artery gave a lateral branch that replaced the perforating branch of the peroneal artery to supply the lateral aspect of the ankle (3 cases, 1%). Conclusion: Arterial variations of the anterior tibial-dorsalis pedis axis occurred in almost 5% of cases. Clinical Relevance: An awareness of the existence of such variations is helpful during a preoperative assessment and could prevent injury during surgery.
