Fatal pulmonary embolism after total hip arthroplasty. Three Japanese cases

It has been reported that the incidence of postoperative pulmonary embolism is significantly lower in Asians than in Westerners, however, several recent reports have cited an increase in the incidence in Asia. We have experienced three cases of fatal pulmonary embolism after total hip replacement in Japanese patients. Our three patients had received no preoperative prophylaxis, even though they had risk factors for pulmonary embolism. Prophylaxis for pulmonary embolism seems necessary in Asian patients who are at risk.
