Abstract:
Objective To locate the points where the superior epigastric artery perforates the rectus abdominis muscle by using the spiral CT,in order to evaluate its control on abdominal complications after breast reconstruction.Methods Fifty cases had received abdominal spiral CT angiography,respectively.Then the coordinate system was established,with the umbilicus as the origin,the umbilicus horizontal line as X axis,vertical umbilical level line as Y axis.The point where superior epigastric artery perforates the rectus abdominis muscle in the coordinate system was located as described above.Results There were 392 perforating points in the rectus abdominis muscle in all 50 cases,with a mean of 7.84 perforators per patient.In the first quadrant,the points where superior epigastric artery perforate the rectus abdominis muscle were located in the range from 1.45 cm to 5.47 cm on the X axis,and in the range from 2.52 cm to 16.38 cm on the Y axis,respectively.In the second quadrant,the points where superior epigastric artery perforates the rectus abdominis muscle were located in the range from 2.02 cm to 6.80 cm on the X axis,and in the range from 2.30 cm to 14.46 cm on the Y axis,respectively.Conclusions The spiral CT angiography has high sensitivity and specificity,it can locate the point where the superior epigastric artery perforates the rectus abdominis muscle,which can avoid to cut extra rectus abdominis muscle.It is significant to reach best postoperative effect with the lowest donor site complications.
