title: Clinicopathological pattern of pulmonary thromboembolism in Chinese autopsy patients: comparison with Caucasian series.
abstract: The clinicopathological data of adult Chinese patients identified to have 'significant pulmonary thromboembolism (PTE)' at autopsy in Queen Mary Hospital (QMH) Hong Kong, from 1990 to 1994 inclusive, were analysed retrospectively. The prevalence of PTE was documented and data were compared with published series of Caucasian patients. The parameters studied included sex-age distribution, associated diseases, symptomatology, site of venous thrombosis, duration of admission and intervals between surgery and death. The rate of PTE was 4.7% (4.5% in males and 5.2% in females). The mean age of PTE patients was significantly higher than that of non-PTE patients (p < 0.001). Two clinicopathological features worthy of note are: (1) as in Caucasian patients, most Chinese patients with 'significant PTE' do not present with leg symptoms although many of them are found to have deep vein thrombosis (DVT) at postmortem; and (2) DVT in these patients is found in the calf veins rather than in the more proximal deep veins. The recently identified racial differences in hemostasis that may contribute to the differences between Chinese and Caucasian people are discussed.
