    Clotted Cliff — Deep Vein Thrombosis & VTE Prevention

    Unilateral calf swelling, warmth, and a positive Homans-like tenderness — never massage the leg, a clot may already be loose

    Clotted Cliff, the MnemoNurse character for Deep Vein Thrombosis & VTE Prevention

    Three days after hip surgery, Cliff's right calf becomes swollen, warm, and tender to touch, and he suddenly develops sharp pleuritic chest pain and shortness of breath while the nurse is assessing him.

    Cliff spent a long postoperative recovery immobile in bed, and venous stasis, vessel wall injury, and hypercoagulability — the classic Virchow's triad — combined to form a clot in his calf vein. A swollen, warm, tender unilateral leg raises suspicion for DVT, confirmed by Doppler ultrasound. The greatest danger is embolization to the lungs, so nurses never massage or vigorously rub a suspected clot and instead focus on anticoagulation and mechanical prevention.

    The story arc

    1. The setup

      Cliff underwent hip replacement surgery and has been largely immobile in bed for three days without his sequential compression devices consistently applied.

    2. The turn

      Cliff's right calf becomes visibly swollen compared to the left, warm to touch, and tender along the posterior calf.

    3. The crisis

      While being assessed, Cliff suddenly develops sharp pleuritic chest pain, shortness of breath, and his oxygen saturation drops to 88%.

    4. The save

      The nurse immediately keeps Cliff on strict bed rest without massaging the leg, raises the head of the bed, applies supplemental oxygen, and notifies the provider for emergent imaging and anticoagulation.
