Abstract

To determine the indication for surgery from the point of pulmonary function, we have performed the unilateral pulmonary artery occlusion test in lung cancer patients. In these patients, we gave a surgery in 13 cases whose total pulmonary vascular resistance were over 700 dyne.sec.cm-5/M2 per body surface area. The pulmonary hemodynamics before and during pulmonary artery occlusion were 549 +/- 82 and 798 +/- 78 dyne.sec.cm-5/M2 in total vascular resistance, 18.7 +/- 3.8 and 27.2 +/- 4.3 cmHg in mean pulmonary arterial pressure and 2.69 +/- 0.36 and 2.73 +/- 4.3 L/min/M2 in cardiac index respectively. In 7 cases out of 13, we performed selective pulmonary artery occlusion test. In pulmonary function test, 10 cases had a chronic obstructive diseases, 2 cases had a disturbance of diffusion and one case has a contractive disease. We gave a lobectomy in 12 cases and completion pneumonectomy in one case. Two of lobectomy cases died in the early phase: 42 and 72 days after surgery due to pulmonary complications. One of these cases needed an additional completion pneumonectomy because of bronchial fistel. Surgical complications were seen in 12 cases. These 13 cases used to be recognized that they have no indication of surgery because of low pulmonary function, however it revealed that we can give a lobectomy through a high intensive care after surgery.
