Objective:
To investigate the incidence and risk factors of symptomatic pulmonary thromboembolism (PTE) in patients following gynecologic surgery or cesarean section in Japan.
Method:
We examined the clinical records of all patients who have undergone gynecologic surgery or cesarean section at 32 hospitals affiliated with the Tohoku University Hospital between 1990 and 1999.
Result:
The total number of gynecologic surgical procedures and cesarean sections were 61648 and 26502, respectively. Twenty-five of the 88150 (0.028%) patients developed clinical PTE. Among the PTE patients who underwent gynecologic surgery, 86% were more than 40 years of age, 36% were obese (BMI>25 kg/m(2)) and 43% had uterine body cancer. Among the PTE patients who underwent cesarean section, 36% were more than 35 years of age and 55% were obese (BMI>29 kg/m(2)).
Conclusion:
Risk factors in Japanese patients undergoing gynecologic surgery may include age and cancer of the uterine body; risk factors for the development of PTE following cesarean section may include age and obesity.
