We will report on the characteristic features of pulmonary embolism (5 cases) and deep vein thrombosis (2 cases), especially on the prodromal symptoms. The onset time was about 2 weeks after operation in 4 out of 5 pulmonary embolism cases, which corresponded to the starting time of the rehabilitation.
A non-infectious, unknown fever and tachycardia were seen just before their onset in 6 out of the total 7 cases. They were considered to be important prodromal symptoms of pulmonary embolism and deep vein thrombosis.
