Abstract:
It is scanty in reports about the anatomy of the medial thoracic free flap, that which one of the perforating arteries of the internal thoracic artery is the main arterial source of this flap is still in dispute. This investigation was based on dissection of 50 sides of adult cadavers under the operating microscope.Among the perforating arteries of the internal thoracic artery in the upper four intercostal spaces, the second perforating artery presents a higher incidence of occurence, it also possesses a larger caliber and distributing area. So that it would be the first choice as a pedicle artery in the transplantation of the medial thoracic free flap. The next choice is the first perforating artery, because its distributing area is larger than that of the third as well as the fourth arteries.The second intercostal space is the widest among all other spaces. The internal thoarcic artery in this space is located more superficial and stands further apart from the lateral border of the sternum than that in the other three intercostal spaces. All these advantages are in favor for taking the second perforating artery as the pedicle artery of the free flap or even to take the internal thoracic artery of the same segment together with it. If a portion of the second costal cartilage isresected, the first two perforating arteries and their related portion of internal thoracic artery can be involved in the pedicle, and the area of the skin flap will be increased to a large extent.Some of the applied anatomy of the transplantation of the medial thoracic free flap has been discussed.
