[Use of percutaneous cardiopulmonary support (PCPS) for extended surgery in patients with T4 tumor]

Since 1991, we have performed operations for tumors invading the upper airway, left atrium or main pulmonary artery with percutaneous cardiopulmonary support (PCPS) stand by support available. Of 15 cases with PCPS stand by, 6 patients actually underwent operation using PCPS. There were three esophageal cancers invading the carina, two lung neoplasms with left atrial invasion and one neoplasm extending to the main pulmonary artery. One of three patients with esophageal cancer had massive bleeding in the trachea resulting in airway obstruction. For this patient, emergency PCPS was carried out followed by the total removal of the thoracic esophagus and combined resection of membranous portion of the carina. As a result, a substantial amount of time (6 hours) was required. The two patients with reconstruction of the carina due to esophageal cancer were also successfully treated by using PCPS. Two patients with malignant pulmonary neoplasms invading the left atrium underwent combined resection of the lung and left atrium using a combination of PCPS and ventricular fibrillation under normothermia. In conclusion, PCPS should be accepted as a standard technique for patients with advanced thoracic malignancies in whom cardiac arrest or ventilation support is thought to be necessary for the complete removal of the tumor.
