Deep Vein Thrombosis, Demographic Characteristics and Risk Factors in Iran

Abstract

Background: Deep vein thrombosis (DVT) can be an ethnicity related disease and an important health issue for health-care systems. Thus, domestic recognition of risk factors and disease characteristics seem to be inevitable. This study was designed to evaluate the epidemiology, basic characteristics, and risk factors in patients with DVT.

Materials and Methods: In this descriptive cross-sectional study, all patients with primary or final diagnosis of DVT, confirmed by Doppler ultrasound in a 5-year period were included. Demographic data and prognosis were extracted from medical files. To evaluate the outcome of the patients after discharge, a phone-call follow-up was performed for all available patients.

Results: Three-hundred seventy-one DVT patients were included with 232/139 male to female ratio. The mean age was 55.72±20.01 years with significant difference between genders (p=0.006). Mean weight was 88.97±10.2 kg with no significant difference between genders (p=0.74). The most common affected veins were common femoral vein (257 cases, 69.2%), followed by Popliteal, iliac, axillary, and subclavian veins. No season preference was seen in DVT occurrence. One-year survival of the patients after discharge was 92.6% and two-year survival was 87.7%.

Conclusion: By knowing local information about this disease, health-care providers can give accurate warnings and suggestions to prevent the probable thrombosis chances. As Iran lacked information about DVT characteristics, this study can be an epidemiologic guide for health-care systems and an opening path for future studies.
