94例腹直肌肌皮瓣肌皮动脉穿支的研究

目的 了解腹直肌肌皮瓣、肌瓣与皮瓣之间的血管穿支的分布，以及在体表的定位和动脉收缩期血流速度。方法 采用彩色超声血管检查仪对９４例进行检测，术中进一步验证检涮 结果。对腹部各区内肌皮穿支出现频率、位置及收缩期血流速度，腹直肌肌皮瓣转移后肌皮穿支动脉的收缩期血流速度进行检测和统计。结果 左右两侧腹直肌肌皮瓣、肌瓣与皮瓣之间血管穿支呈非对称性分布，脐周的肌皮穿支含量占８１．１％，同一分区内第二条穿支的

COLOR-FLOW DUPLEX DOPPLER SCANNING STUDY IN THE TRAM FLAP PERFORATORS:A REPORT OF 94 CONSECUTIVE PATIENTS

Objective To investigate the location of transverse rectus abdominis musculocutaneous(TRAM) flap perforators on abdomen skin and the peak systolic flow velocities of the perforators.Methods A series of 94 consecutive patients's TRAM flap perforators were detected by color flow duplex Doppler scanning peroperatively. Perforator locations were tabulated on the abdomen skin according to their vertical position relative to the umbilicus and their lateral location relative to the abdominal midline. Results The perforators on both left and right side of TRAM flap were quite not symmetry. The peri umbilical region contained 81.1% of the perforators. All perforators were detected with peak systolic flow velocities ranging from 5 to 81 cm/s.Conslusion The preoperative color flow Doppler localization of TRAM flap perforators improves the surgeon's ability to design the flap in order to capture the dominant vessels, and select single or double pedicle and free TRAM flaps based on each patient's individual characteristics.
