磁共振成像与阿基米德法测量乳房体积在即刻假体乳房再造中的效果比较

Comparison of effects between MRI imaging and Archimedes method for measurement of breast volume on immediate implant breast reconstruction

目的 探讨磁共振成像（MRI）与阿基米德法测量乳房体积在即刻假体乳房再造中的临床效果.方法 选择青岛大学附属医院乳腺中心2011年3月至2013年3月行即刻假体乳房再造的乳腺癌患者44例.其中试验组22例,采用基于MRI的乳房体积及相关径线测量方法,指导选择合适的乳房假体;对照组22例,采用传统的阿基米德法及临床经验来选择乳房假体.选择3名未参与手术的乳腺外科及整形外科医师对两组患者术后乳房形态进行评价.结果 44例患者术后恢复均顺利,无1例并发感染,切口均愈合良好.术后乳房形态评价,试验组优良21例（95.5％）,差1例（4.5％）;对照组优良16例（72.7％）,差6例（27.3％）,两组比较差异有统计学意义（P＜0.05）.结论 采用MRI的乳房体积及相关径线测量方法,对于即刻假体乳房再造术中假体的选择有着重要的指导作用.

Objective To conduct the comparative study of the measurement of breast volume by MRI imaging and Archimedes method in immediate implant breast reconstruction.Methods A total of 44 patients who were diagnosed as breast cancer and undergone immediate implant breast reconstruction were selected from March 2011 to March 2013.22 cases were guided to select suitable breast implants by measuring the breast volume and correlative radial line based on MRI imaging.Control group containing 22 cases were guided to select breast implants by traditional Archimedes method and clinical experience.3 breast surgeons and plastic surgeons who did not participate in the operation were selected to judge the postoperative breast shape.Data of two groups were analyzed by using chisquare test.Results All the patients recovered smoothly after operation without infection,and the wound healed well.The breast shape was evaluated.21 cases （95.5 ％） were good in test group and 1 case （4.5％） was poor;16 cases （72.7％） were good in control group and 6 cases （27.3） were poor.The comparison between the test group and control group had statistical significance （P＜0.05）.Conclusions The method to measure the breast volume and correlative radial line based on MRI imaging has important values for selecting breast implants in immediate implant breast reconstruction.It could be extensively used in clinical practice.
