THROMBOENDARTERECTOMY IN CHRONIC PULMONARY THROMBOEMBOLISM (CASE REPORT)

Chronic pulmonary thromboembolic disease is entrapment of thrombus in pulmonary arteries from a single episode or repeated embolic episodes that subsequently organize, or thrombi that develop inside the pulmonary arteries into firm, fibrous tissue that becomes incorporated into the vessel wall.We operated 7 patients with end stage chronic pulmonary thromboembolism over a two year period at our center. Four patients had good function class after operation on follow up at 6 to 12 months and we administered warfarin prophylaxis (with international normalized ratio, INR, of 3) for them.Three patients died in hospital postoperatively. We used extracorporeal membrane oxygenation (ECMO) for one of them but it failed on the third postoperative day.
