Anatomical study of the perforating vessels of the lower leg
The Anatomical Record, 1999
Difficulty of soft tissue defects of the lower leg demands the development of new methods to treat such defects. The aim of this study is the examination of perforators and the various ways of blood supply to the skin in the lower leg. Provided with certain regularity, we would be able to cure soft-tissue defects also in the difficult zone of the distal segment and on the dorsum of the foot not harming vessels and not affecting mobility of muscles. Subcutaneous island-flaps supplied by perforating vessels could replace free flaps.

Introduction: Palpation of peripheral arterial pulse is commonly used to evaluate the patients with arterial diseases. Dorsalis pedis artery is commonly used to evaluate arteriosclerotic diseases in the lower limb. Aim: Aim of the present study is to observe the course of fibular (peroneal) artery continuing as dorsalis pedis artery associated with hypoplastic anterior tibial artery as it is a rare anatomical variation. Material and Methods: Fifty (50) formalin embalmed lower limb specimens were dissected and studied to observe the anatomical variation of fibular (peroneal) artery continuing as dorsalis pedis artery associated with hypoplastic anterior tibial artery. Results: In one specimen of lower limb the fibular (peroneal) artery was larger than usual and crossed the lower end of interosseous membrane and continued as dorsalis pedis artery. Posterior tibial artery had a normal course and divided distally into medial and lateral plantar arteries, however, the anterior tibial artery was found to be hypoplastic. Conclusions: A good knowledge about the arterial variations around the ankle is important to the vascular and orthopaedic surgeons to prevent the occurrence of any complications during arterial reconstructive studies.
Anatomic study of septocutaneous system of the human fetuses’ lower leg: Posterior tibial artery
Vojnosanitetski pregled
Background/Aim. Lower-leg septocutaneous system of perforating blood vessels represents the vascular basis of fasciocutaneous flaps. Additionally, it is of a particular importance when designing distally based fasciocutaneous flaps which represent the ?workhorse? in the reconstruction of the distal third of the lower leg and foot. The aim of this study was to analyse the vascular anatomy of posterior tibial artery and its septocutaneous (fasciocutaneous) perforating arterial vessels. Methods. The dissection was conducted on 20 fetuses of both sexes and of gestational age from 20 to 28 weeks. Cluster analysis was applied to the data on vascular anatomy of posterior tibial artery and its septocutaneous performating arterial vessels. Results. A total of 212 perforating arterial vessels was identified. The average number of perforating arterial vessels was 5.32 (ranging from 4 to 7). It was identified that septocutaneous perforating blood vessels are more likely to be found at certain l...
Clinical features of a rare anatomical variation of the posterior tibial and fibular arteries
The posterior tibial artery normally arises from tibial-fibular trunk at the popliteal fossa, together with the fibular artery. The classic course of the posterior tibial artery is to run between the triceps surae muscle and muscles of the posterior compartment of the leg before continuing its course posteriorly to the medial malleolus, while the fibular artery runs through the lateral margin of the leg. Studies of both arteries are relevant to the fields of angiology, vascular surgery and plastic surgery. To the best of our knowledge, we report the first case of an anastomosis between the posterior tibial artery and the fibular artery in their distal course. The two arteries joined in an unusual " X " format, before division of the posterior tibial artery into plantar branches. We also provide a literature review of unusual variations and assess the clinical and embryological aspects of both arteries in order to contribute to further investigations regarding these vessels. Resumo A artéria tibial posterior e a artéria fibular se originam do tronco tibiofibular, na fossa poplítea. A trajetória clássica da artéria tibial posterior é correr entre o tríceps sural e os músculos do compartimento posterior da perna, e, então, seguir posteriormente ao maléolo medial. Já a artéria fibular corre na margem lateral da perna, seguindo profundamente aos músculos. O estudo dessas artérias é relevante para o campo da angiologia, cirurgia vascular e cirurgia plástica. O presente trabalho é o primeiro relato de caso de uma anastomose entre ambas artérias, na porção distal de suas trajetórias. Tais artérias se anastomosaram em formato de " X " , antes da divisão da artéria tibial posterior em ramos plantares. Foi feita uma revisão de literatura das variações de tais artérias, dando ênfase ao aspecto clínico e embriológico, de modo a contribuir para novas investigações sobre esses vasos. Palavras-chave: variação anatômica; cadáver; artéria fibular; artéria tibial posterior; artéria poplítea.
Clinical anatomy of the arterial supply of the human patellar ligament
Surgical and Radiologic Anatomy, 2002
The arterial supply of the human patellar ligament has been systematized on 20 knee joints. After intravascular injection of colored natural latex, the blood supply to the extensor apparatus of the knee was studied by anatomical dissection and tissue transparentation techniques. Three arterial pedicles (superior, middle and inferior) were observed placed on each side of the patellar ligament. Medial pedicles had their origin from the descending and the inferior medial genicular arteries. The lateral pedicles took their origin from the lateral genicular arteries and the recurrent tibial anterior artery. Two main vascular arches anastomosed with these pedicles: the retropatellar and the supratubercular. Both arterial pedicles and anastomotic arches gave rise to a peritendinous network, characterized by a high vascular density next to poles of the patellar ligament. Only the anastomotic arches gave rise to collateral vessels that pierced the tendon, which revealed two vascular segments in the arterial supply of the patellar ligament (bipolar pattern). The upper segment was supplied by deep vessels from the retropatellar arch, whereas the inferior segment received superficial vessels from collaterals of the supratubercular arch. These intratendinous vessels anastomosed in the middle third of the patellar ligament.

Blood supply of subcutaneous tissue in the leg and its clinical application
Clinical Anatomy, 1995
The vascular anatomy of the subcutaneous or adipose layer of the leg is described. The major arteries of the distal thigh and leg were injected with either a colored latex or an India ink and gelatin mixture to demonstrate the principal sources of blood supply to the skin and the superficial tissues of the leg. Microdissection and the techinique of Spalteholz for dehydrating and clearing the tissues (rendering them transparent) facilitated the study of the direct and indirect arterial branches which form the three principal networks: the deep fascia, the subcutaneous or adipose layer, and the skin or the dermoepidermic layer. The results are of practical importance since the fascio-subcutaneous tissue layer can be used as a flap for covering soft tissue defects of the leg.
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.
