Abstract:
This is a Prospective Cohort Study of Six hundred eleven women who underwent caesarean
section during a period of nine months (1st of March 2003 to 31st of November 2003) in the
above unit. Data was collected by an Interviewer-based pretested questionnaire, from case
notes, physical examination and by doing non invasive colour Duplex ultrasonography and
real time ultrasound scan.. Five hundred and four out of six hundred eleven women
responded to this study. The response rate was 83.3 percentage. Based on clinical diagnosis
14 cases were detected as haying DVT. Out of these 14 cases 6 had continned DVT by
objective tests. Out of the 6 continned cases one had pulmonary thromboembolism (PIE).
The risk factors identified for DVT in our study include emergency caesarean section, age -
35years, para -4, pre eclampsia, current major illnesses, current infections immobility prior
to surgery. The very high risk for D VT was identified as of risk score - 10 or risk factors 5
or more.The sensitivity of clinical diagnosis is 42.8 percentage. Thromboembolic disease is
not uncommon among women after caesarean section in Sri Lanka. The long standing belief
that thromboembolism is rare among Sri Lankan women is at least partly because of under
diagnosis. So diagnosis treatment may prevent morbidity and mortality due to DVT and
PTE.
