概要	The aim of this study was to evaluate the relationship between pulmonary arterial pressure and distal embolisation during catheter fragmentation for the treatment of acute massive pulmonary thromboembolism with haemodynamic impairment. 25 patients with haemodynamic impairment (8 men and 17 women; aged 27-82 years) were treated by mechanical thrombus fragmentation with a modified rotating pigtail catheter. After thrombus fragmentation, all patients received local fibrinolytic therapy, followed by manual clot aspiration usinga percutaneous transluminal coronary angioplasty (PTCA) guide catheter. Pulmonary arterial pressure was continuously recorded during the procedure. The Friedman test and Wilcoxon test were applied for statistical analysis. Distal embolisation was confirmed by digital subtraction angiography in 7 of the 25 patients. A significant rise in mean pulmonary arterial pressure occurred after thrombus fragmentation (before: 34.1 mmHg; after: 37.9 mmHg; p<0.05), and this group showed a significant decrease in mean pulmonary arterial pressure after thrombus aspiration (25.7 mmHg; p<0.05). No distal embolisation was seen in 18 of the 25 patients, and a significant dec
