RESUMO
AIM: The aim of this study was to assess the value of discontinuing antiplatelet treatment prior to surgery for skin cancer with loss of skin of up to 10 cm in diameter. The study hypothesis postulated equivalence between discontinuation of antiplatelet therapy and continuation of these drugs during the perioperative period with regard to risk of cutaneous complications. PATIENTS AND METHODS: This was a prospective, randomised study comparing two groups of patients on long-term antiplatelet treatment scheduled for surgery for skin carcinoma. In the first group, patients underwent surgery without change to their antiplatelet therapy while in the second, antiplatelet treatment was discontinued and substituted with either flurbiprofen or isocoagulant fractionated heparin or calcium heparin. Sixty patients took part in the study. Statistical analysis using ANOVA and Mann-Whitney non-parametric tests was performed to compare the following variables: age, sex, number of pre- and post-operative consultations, complications (haemorrhage, haematoma, separation and infection) and quality of wound healing. RESULTS: No statistically significant difference was seen between the two groups regarding either complications or quality of wound healing. CONCLUSION: There appear to be no rational grounds for discontinuing antiplatelet therapy in advance of skin cancer surgery involving loss of skin of up to 10 cm in diameter.
