[Design of myocutaneous flap with color Doppler flow imaging technique for breast reconstruction in breast cancer after operation and radiotherapy].
OBJECTIVE
To investigate the method and effect of axial pattern myocutaneous flap in reconstructing breast by using color doppler flow imaging (CDFI) technique.


METHODS
Suitable axial myocutaneous flaps were selected according to the character of the focus in 26 cases of breast cancer after operation and radiotherapy. All the axial pattern myocutaneous flaps were designed on the basis of traditional design method before operation; then, CDFI with high resolution was used to examine the starting spot, exterior diameter, trail and length of the myocutaneous flaps' major artery. The myocutaneous flaps were redesigned according to the results of CDFI and transferred to reconstruct the breasts. The results of operation and examination were investigated.


RESULTS
According to the CDFI, only one thoracodorsal artery's blood current was slow, its wall was rough and presented with arteriosclerosis. The blood flow was fluent and the vessel wall was smooth with other supplying arteries in the flaps. And no embolism, sclerosis or absence of blood vessel was found. The starting spots, exterior diameters, trails and anatomic layers of the major supplying arteries of the flaps were displayed clearly with CDFI, in accordance with the results of operation. Twenty-one cases of latissimus dorsi myocutaneous flap, 4 cases of the contralateral transverse abdominis myocutaneous flap and 1 cases of the bilateral transverse abdominis myocutaneous flap were used in this group. The flaps survived and healed well, the breasts were reconstructed well with perfect appearance, shape and sensation.


CONCLUSIONS
CDFI is a simple, visualized and noninvasive method for designing the axial pattern myocutaneous flap in breast reconstruction, it can provide more scientific and accurate evidence for preoperative determination of myocutaneous flap transplantation.
