Abstract
Filler injection or implantation is a progressing revolutionary subject. Although the widely available kinds in many implications are considered safe, post filler adverse events are not uncommon. These reactions range from mild reactions such as edema or erythema to detrimental reactions such as recurrent infected granuloma or vascular occlusion, which are predominantly related to non-FDA approved materials. Here, we presented a patient with a significant history of gluteal augmentation using unlicensed silicone who developed extensive retroperitoneal fibrosis complicated by deep venous occlusions and obstructive uropathy.
