Abstract:
The arteries of the breasts of 25 Chinese female cadavers, injected with color latex, were dissected and observed by surgical microscope. These arteries originate from the first, second and third perforating branches of the internal thoracic artery. They were classified into five types. The two branch type occured most frequently (54%), and is musculoadenocutaneous in nature. The distribution of this type of artery is in four directions, one branch to the nipple, the second branch to the axilla, the third branch to the sternum and the last branch to the clavicle. The second perforating branch is the largest in diameter, 0.92 mm., the first and third perforating branches come next. The area of distribution of the second perforating branch is also the largest, 6265.50 mm2, and the third and first perforating branches come next. The first perforating branch crosses the 4 th rib in 52%, and that of the second perforating branch in 43%. The arteries supplying the medial portion of the breast have an extensive anastomoses (48%) with those arteries of the lateral portion.
