Pulmonary embolectomy for acute massive pulmonary embolism under percutaneous cardiopulmonary support.
Portable percutaneous cardiopulmonary support (PCPS) with heparin-coated circuits and a biopump was employed in a patient who had a massive pulmonary embolism with circulatory collapse after stripping of varicosities of the leg. Emergency pulmonary embolectomy was successfully performed. The main pulmonary incision was facilitated by cross-clamping of the main pulmonary arterial root. The bypass circuit was kept closed, and used with the normothermic beating heart without converting to conventional total cardiopulmonary bypass. Blood flow from the lung was removed by pump suction, stored in the reservoir, and intermittently returned to the venous circulation. Heparin was added to the circuits to keep the activated clotting time greater than 300 sec. In massive pulmonary embolism, PCPS is useful for preoperative, intraoperative, and postoperative support.
