ABSTRACT
Polyacrylamide hydrogel (PAAG) was once widely used in breast augmentation in China. Although it had been banned for augmentation mammaplasty in 2006, a large number of patients whose breasts were augmented with the gel injection have continued to seek medical advice because of its complications. The clinical management of these complications has never been standardised. The data of a total of 235 patients with complications following PAAG-injected breast augmentation have been summarised and the types and causations analysed. Magnetic resonance imaging (MRI) was undertaken in 228 patients with palpable masses, breast pain or tenderness, asymmetry or deformity and functional or psychological problems to eliminate neoplasm, infection and to delineate the diseases. The surgical gel evacuation via periareolar incisions was performed for all patients and immediate silicone breast prostheses were implanted in 108 patients and were delayed in 28 cases by 6 months. Most patients (214/235) of the group were satisfied with the treatment, and symptoms disappeared after removal of the gel. The gel distribution and involved tissue were well defined and neoplasm was ruled out by MRI. Postoperative MRI in 68 patients revealed that no obvious PAAG remaining. In either immediate or delayed reconstructive patients with silicone breast implants, good breast contour presented. A diagnosis and management strategy for these complications is proposed. In conclusion, the breast masses, pain and deformity are major complications after PAAG-injected breast augmentation. Psychological problems should be paid attention to. MRI is a sensitive and accurate method for diagnosis and treatment evaluation. Surgical removal of injected gel is the preferred method for complication management. The implantation of silicone prostheses for breast contour restoration after PAAG evacuation is effective for patients under strict selection. Our strategy for treating PAAG-related complications proved useful.
