Abstract:

BACKGROUND: At present, design of pedicled island skin flap with arterial arch at the superior border of abductor hallucis muscle mainly depends on clinician’s abstract thinking, which makes it difficult for quantitative analysis and exchange learning, and makes it limited in clinical application.
OBJECTIVE: To perform the three-dimensional reconstruction of pedicled island skin flap with arterial arch at the superior border of abductor hallucis muscle, and to establish visible models of the flap.
METHODS: One fresh adult cadaver specimen was collected and perfused with the mixture of lead oxide-gelatine through anterior tibial artery and posterior tibial artery, and then received spiral CT scanning. The branch of anterior medial malleolus artery, medial tarsal artery and the superficial branch of medial plantar artery as well as its anastomotic branch were reconstructed with mimics10.0 software, in order to observe the constitute, track-way and distribution of arterial arch at the superior border of abductor hallucis muscle. According to the feature of anatomical structures, reconstruction was conducted in skin and vessel to obtain three-dimensional arterial skin flap structure.
RESULTS AND CONCLUSION: The layers of three-dimensional reconstruction were distinctively displayed, and the arterial arch at the superior border of abductor hallucis muscle was displayed well with strong physical sense and clear relationship between skin and arteries. The morphology of various anatomical structures could be bserved clearly on the three-dimensional reconstruction image, especially the formation of arterial arch at the superior border of abductor hallucis muscle and its surface projection. Three-dimensional reconstruction of pedicled island skin flap with arterial arch at the superior border of abductor hallucis muscle may provide great value for basic research, clinical experiments and surgical planning, and provide visual reference for the individual operation design and can be able to enhance the successful rate of surgery.
