Complications of breast augmentation with injected hydrophilic polyacrylamide gel.

Since 1997, the hydrophilic polyacrylamide gel (PAAG), an injectable alloplastic biomaterial, imported from the Ukraine has been used for augmentation mammaplasty in China. There were twelve patients with various complications visiting our hospitals after breast augmentation with injected hydrophilic polyacrylamide gel by other clinics, even though such procedures are not performed in our clinical practices. The complications included four cases of PAAG-induced multiple induration and lumps, and one with lactation, three cases of hematoma, two cases of inflammation (infection), and persistent mastodymia, unsatisfactory contour results and abnormal skin sensations in each case.
