Abstract Introduction Surgery is a risk factor for flares in people with gout. However, gout flares after endovascular interventional procedures are not well understood. The aim of this study was to evaluate the clinical features and risk factors for gout flare that develop during the postsurgical period including endovascular procedures. Methods We enrolled 222 patients with gout who developed postsurgical gout and 196 controls who had histories of gout but did not develop gout flares after surgery within 20 days. Clinical characteristics of patients who developed a postsurgical gout flare were compared with the controls. Results The rate of endovascular interventional procedures was higher (38.74% vs. 13.48%, P < 0.001) in the flare group than in the no-flare group and lower in orthopedic surgery (13.96% vs. 41.84%, P < 0.001). The Cox model showed that endovascular interventional procedures (HR, hazard ratio 1.752; 95% CI, confidence interval 1.126–2.724, P = 0.013) and presurgical uric acid levels of ≥ 7 mg/dl (HR 1.489; 95% CI 1.081–2.051, P = 0.015) were significantly associated with increased risks of postsurgical gout flare, and taking colchicine before surgery were significantly associated with decreased risk of postsurgical gout flare (HR 0.264; 95% CI 0.090–0.774, P = 0.015). There was no significant difference in the types of endovascular interventional procedures between the flare group and the no-flare group. Conclusions Patients with a history of gout should be more alert to recurrence gout flares after endovascular interventional procedures. Adequate presurgical control of serum uric acid levels and/or prophylactic treatment with colchicine will help prevent gout flares during the postsurgical period.
