D. Dissolution of residual thrombus after balloon thromboembolectomy.

DISCUSSION: Conditions that would cause undesirable consequences from rethrombosis (e.g., venous thrombosis, additional embolization from the cardiac source, pre-existing ischemia) are indications for postoperative heparinization. Heparin prevents additional clotting; it is not a thrombolytic agent.
