BACKGROUND/OBJECTIVE: Cushing syndrome (CS) is a prothrombotic state associated with an increased risk of postoperative venous thrombosis. We aim to present the case of a patient with Cushing disease who underwent pituitary surgery and subsequently developed acute lower extremity deep venous thromboses after anticoagulation was stopped. CASE REPORT: We present the case of a 57-year-old woman who was admitted for intra-abdominal abscesses after a gastric bypass surgery and was found to have evidence of severe CS. Her 24-hour urinary free cortisol level was 898.6 μg/24 h. She was diagnosed with Cushing disease and underwent transsphenoidal resection of a pituitary adenoma, with an appropriate postoperative drop in the cortisol level. She received thromboprophylaxis during hospitalization; however, this was discontinued upon discharge, on postoperative day 9, because she was ambulating. Five days after hospital discharge and 14 days after her surgery, she developed left lower extremity edema and was found to have 4 deep venous thromboses. DISCUSSION: As previously described, thrombotic risk can be elevated for at least 1 month after surgery for CS, and thromboprophylaxis can decrease this risk. CONCLUSION: This case highlights the need for clear recommendations for the duration of postoperative thromboprophylaxis in patients with CS. Clinicians should consider continuing thromboprophylaxis for at least 1 month after surgery for CS.
