| description | This skill suggests perioperative prophylaxis for venous thromboembolism in patients with Cushing's syndrome undergoing surgery. Use when preparing a CS patient for any surgical procedure; triggers include "CS patient pre-op", "Cushing's syndrome surgery", "perioperative VTE prophylaxis CS". |
Perioperative Prophylaxis for Venous Thromboembolism in Cushing's Syndrome
STEP 1 — Gather Information
Confirm diagnosis of Cushing's syndrome (elevated UFC, late-night salivary cortisol, or dexamethasone suppression test); note type and urgency of surgery; assess baseline VTE risk factors (prior VTE, malignancy, obesity, immobilization, estrogen use, thrombophilia); review bleeding risk (active bleeding, coagulopathy, recent surgery, platelet count, anticoagulant use); obtain baseline coagulation labs if indicated.
STEP 2 — Rule In / Rule Out
Is the patient with Cushing's syndrome scheduled for a surgical procedure? If yes, proceed to assess thrombotic and bleeding risk; if no, routine VTE prophylaxis is not indicated solely for Cushing's syndrome (consider standard indications).
STEP 3 — Classify or Stratify
Stratify thrombotic risk: high if major surgery (e.g., bilateral adrenalectomy, transsphenoidal resection) plus any additional VTE risk factor (prior VTE, malignancy, obesity >30 kg/m2, prolonged immobilization); moderate if major surgery without additional risk factors or minor surgery with risk factors; low if minor surgery without risk factors. Assess bleeding risk: high if active bleeding, coagulopathy, platelet <50k, recent intracranial hemorrhage, or planned neuraxial anesthesia.
STEP 4 — Decide
If thrombotic risk is high and bleeding risk is low/moderate, initiate pharmacologic prophylaxis (e.g., enoxaparin 40 mg SC daily or unfractionated heparin 5000 units SC q8h) starting pre-op and continue until ambulatory or discharge; if thrombotic risk is moderate and bleeding risk low, consider pharmacologic prophylaxis or mechanical compression devices; if bleeding risk high, use mechanical prophylaxis only and hold pharmacologic agents until bleeding risk resolves.
Clinical Guardrails / Mimics / Pitfalls
Do not administer pharmacologic prophylaxis in patients with active bleeding, severe thrombocytopenia, or contraindications to anticoagulants; avoid neuraxial blockade while on therapeutic anticoagulation; monitor for heparin-induced thrombocytopenia if heparin used >4 days; ensure timely discontinuation post-op to prevent bleeding; mechanical prophylaxis alone is insufficient for high thrombotic risk.
Concrete Clinical Example
A 48-year-old man with ectopic ACTH syndrome scheduled for laparoscopic adrenalectomy. He has a prior provoked DVT, BMI 32, and no bleeding disorder. Thrombotic risk high (major surgery + prior VTE), bleeding risk low. Start enoxaparin 40 mg SC daily pre-op and continue for 7 days post-op until ambulatory.
