The effect of anti-thyroid drug treatment duration on thyroid gland microvessel density and intraoperative blood loss in patients with Graves' disease

Abstract

Background. Preoperative preparation of the patient with Graves' disease (GD) is crucial to avoid intraoperative or postoperative complications associated with anesthesia or surgery. We aimed to evaluate thyroid blood flow and microvessel density in patients with GD according to antithyroid drug (ATD) treatment, preoperatively.
