Deep venous thrombosis : Five years analysis at Prapokklao Hospital

Abstract

Objective : To determine the age, sex, underlying risk factors and clinical manifestations of patients with deep venous thrombosis at Prapokklao Hospital.

Materials and methods : Retrospective descriptive study of the medical records with diagnosis of deep venous thrombosis at Prapokklao Hospital in five year period, from October 1, 1999 to September 30, 2004. Diagnosis of deep venous thrombosis was based on consistent clinical manifestations and confirmed by contrast venography or compression ultrasonography.

Results and conclusion : There were 41 cases of deep venous thrombosis. The male to female ratio was 1.9 : 1 and the median age was 62 years. Most patients (95.1 percent) had one or more risk factors. The three most common risk factors were age older than 40 years, immobilization and malignancy. (82.9, 56.1 and 26.8 percent respectively). The most common clinical manifestation was localized swelling (100 percent). Clinical manifestations of inflammation were uncommon. This hospital-based study provides helpful fundamental data of deep venous thrombosis in the Thai population but there are many unstudied aspects of the issue. Further study may be required.
