Question

A 60-year-old man on ICU requires anticoagulation for a new proximal DVT. He has a platelet count of 42 × 10⁹/L due to bone marrow suppression from chemotherapy. What is the recommended platelet threshold for safe therapeutic anticoagulation?

Accepted Answer

Therapeutic anticoagulation can generally be given if platelets are >50 × 10⁹/L; for platelets 25-50 × 10⁹/L, a reduced dose may be considered with careful monitoring; below 25 × 10⁹/L, the bleeding risk usually outweighs the benefit and anticoagulation should be withheld or an IVC filter considered

Answer

Anticoagulation is absolutely contraindicated at any platelet count

Answer

Platelets must be >100 × 10⁹/L

Answer

Anticoagulation can be given regardless of platelet count

Answer

Only oral anticoagulants are safe at low platelet counts
