Efficacy and safety of topical nitroglycerin in the prevention of mastectomy flap necrosis: a systematic review and meta-analysis.

ABSTRACT: Flap necrosis is a common complication after mastectomy, and nitroglycerin (NTG) ointment has been used successfully to treat it. However, it is not clear whether topical NTG can completely prevent the occurrence of flap necrosis after breast cancer surgery, and it is also unclear whether this treatment may cause side effects. Three randomized controlled trials (RCTs) and two retrospective cohort studies (RCSs) were included in our investigation. This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We found that NTG significantly reduced the rates of mastectomy flap necrosis, full-thickness flap necrosis, and debridement as well as the rate of early complications other than flap necrosis. However, there was no significant difference in drug-related adverse reactions, explantation, superficial flap necrosis, infection, hematoma or seroma between the NTG and placebo groups.
