The most important problem in fat transplantation is the unpredictable rates of resorption. Deferoxamine (DFO) is an iron-chelating agent with many useful functions including stimulating angiogenesis and antioxidant nature. The purpose of the study is to evaluate the effects of DFO on fat graft viability in rat model. A total of 24 Wistar rats were divided into three groups and 0.5 g of the left inguinal fat pad was extracted. In control group, fat grafts were implanted to the parascapular area without performing any procedure. In sham group, they were implanted in 0.2 mL saline solution followed by serial saline injections for 1 month. In the study group, fat grafts were implanted in 0.2 mL saline solution and 300 mg DFO followed by serial DFO injections for 1 month. At the postoperative second month, fat grafts were taken back and sent for histopathologic examination. The weight measurements of biopsy specimens in the …
