目的 探讨聚丙烯酰胺水凝胶注射隆乳术后分布的有效诊断方法.方法 对聚丙烯酰胺水凝胶注射隆乳术后的患者进行双侧乳房MRI薄层扫描(层厚1 mm,t2_ps3d_cor序列),在计算机上运用Amira电脑软件模块对扫描信息分别进行体积重建和表面重建,观察水凝胶的分布范围和部位,并计算其体积.结果 自2007年3月以来,于临床应用23例(46只乳房),其中5例(10只)水凝胶位于乳房后间隙,包膜完整,分布均匀,无移位;6例(12只)注射的水凝胶包膜不完整,形态不规则,边缘不整,呈多处散在的团块分布;11例(22只)水凝胶浸及胸大肌内、胸大肌后方、乳腺组织内和皮下,1例(2只)外院双侧取除水凝胶术后复查发现仍有少量残留,散在分布于乳腺及变性肌肉组织中.初次就诊的22例(44只)注射水凝胶的总体积为220.309～372.371 ml,平均306.328ml.结论 MRI三维重建能清晰显示注射物的体积和分布范围,可以有效地指导水凝胶的手术取除.
目的 探討聚丙烯酰胺水凝膠註射隆乳術後分佈的有效診斷方法.方法 對聚丙烯酰胺水凝膠註射隆乳術後的患者進行雙側乳房MRI薄層掃描(層厚1 mm,t2_ps3d_cor序列),在計算機上運用Amira電腦軟件模塊對掃描信息分彆進行體積重建和錶麵重建,觀察水凝膠的分佈範圍和部位,併計算其體積.結果 自2007年3月以來,于臨床應用23例(46隻乳房),其中5例(10隻)水凝膠位于乳房後間隙,包膜完整,分佈均勻,無移位;6例(12隻)註射的水凝膠包膜不完整,形態不規則,邊緣不整,呈多處散在的糰塊分佈;11例(22隻)水凝膠浸及胸大肌內、胸大肌後方、乳腺組織內和皮下,1例(2隻)外院雙側取除水凝膠術後複查髮現仍有少量殘留,散在分佈于乳腺及變性肌肉組織中.初次就診的22例(44隻)註射水凝膠的總體積為220.309～372.371 ml,平均306.328ml.結論 MRI三維重建能清晰顯示註射物的體積和分佈範圍,可以有效地指導水凝膠的手術取除.

Objective To investigate the effective diagnostic method for the patients with polyacrylamide hydrogen injection for augmentation mammaplasty.Methods MRI scanning (layer thickness 1mm,t2_ ps3d_cor alignment) was performed on 23 patients with polyacrylamide hydrogen injection for augmentation mammaplasty.The data were imported into computer and processed.3D reconstruction and analysis modules were nm subsequently to do the volume recunstmction and surface reconstruction to obtain stereoscopic images of the gel and adjacent structures in virtual reality,and to calculate the volume of the hydrngel.Results Among the 23 patients (46 breasts),the injected hydrngel with integrity capsule existed in retromammary space with no malpostition in 5 cases (10 breasts).The capsule was not integrally formed and hydrogel was separately distributed with irregular edge in 6 patients (12 breasts).The pectoris major space,subcutaneous and gland invasion was found in 11 patients (22 breasts).Small amount of hydrogel sparsely distributed in mammary gland and degenerative muscular tissue in 1 patient (2 breasts) who had received extracting surgery before.The volume of hydrngel ranged from 220.309 ml to 372.371 ml (mean:306.328 ml) in 22 untreated patients (44 breasts).Conclusions The volume and distribution of hydrogel can be known clearly by 3D MRI reconstruction technique.This feasible technique is helpful in removing the hydrogel completely.
