RESUMEN
<p><b>OBJECTIVE</b>To investigate the significance of preoperative MDCT angiography for breast reconstruction with abdominal flap.</p><p><b>METHODS</b>Preoperative MDCT angiography scans were performed on 34 patients who underwent breast reconstruction with abdominal flaps during December 2006 to June 2009. The operation was designed based on the MDCT results. Then the MDCT results were proved intraoperatively. Another 22 cases who underwent breast reconstruction with abdominal flap without preoperative MDCT were selected as controls. The rate of operative method change, the operation time and the flap necrosis were compared between the two groups.</p><p><b>RESULTS</b>The preoperative design changed in 23.53% of the patients, based on the MDCT results. No one had any method change intraoperatively in the group with MDCT. The operative method was changed intraoperatively in 13.64% of the patients in the control group. The mean time spending on flap harvesting was (2.51 +/- 0.64) h in the experimental group and (4.42 +/- 0.21) h in the controlled group (P < 0.05). The rate of complication was 6.12% in the experimental group and 12.5% in the control group (P = 0.017).</p><p><b>CONCLUSIONS</b>Preoperative MDCT angiography is an easy and reliable method for breast reconstruction with abdominal flap. The preoperative design can be more reasonable. It helps to save the operation time and reduce the risk.</p>
