Description
Summary:Abstract Background Pituitary surgical intervention remains the preferred treatment for Cushing’s disease (CD) while postoperative venous thromboembolism (VTE) is a significant risk. Whether to prescribe pharmacological thromboprophylaxis presents a clinical dilemma, balancing the benefit of reducing VTE risk with the potential for increasing hemorrhagic events in these patients. Currently, strong evidence and established protocols for routine pharmacological thromboprophylaxis in this population are lacking. Therefore, a randomized, controlled trial is warranted to determine the efficacy and safety of combined pharmacological and mechanical thromboprophylaxis in reducing postoperative VTE risk in patients with CD. Methods This investigator-initiated, multi-center, prospective, randomized, open-label trial with blinded outcome assessment aims to evaluate the efficacy and safety of combined pharmacological and mechanical thromboprophylaxis compared to mechanical thromboprophylaxis alone in postoperative patients with CD. A total of 206 patients diagnosed with CD who will be undergoing transsphenoidal surgery will be randomized in a 1:1 ratio to receive either combined pharmacological and mechanical thromboprophylaxis (intervention) or mechanical thromboprophylaxis only (control). The primary outcome is the risk of VTE within 12 weeks following surgery. Discussion This trial represents a significant milestone in evaluating the efficacy of combined pharmacological and mechanical prophylaxis in reducing VTE events in postoperative CD patients.
