The study on the anatomy of the deltopectoral flap that extended to the area of the neck, should or back was carried out in 30 fresh adult cadavers by means of dissecting under microscope, MO-Pd radiography, carbon-ink injection of arteries. We observed the origin of cutaneous arteries of the flap and the running direction, length and diameter of vessel branches and its anastomotic network. The clinical applications and the prospect of the flap are described.
