Prevalence of deep vein thrombosis in heparin prophylaxis patients in general surgery department

One of the complications of surgery operation is deep vein thrombosis. Because of its dangerous side effects, it is important to prevent it. The purpose of this study was to determine the incidence of deep venous thrombosis in patients with DVT-associated risk factors

This cross-sectionalstudy was performed on 100 patients at high risk for probability of DVT incidence in accordance with the known risk factors of the attached checklist over one-year interval in the General Surgery Department of Imam Reza hospital. All patients underwent lower extremity bandages during operation and prophylaxis with 5,000 units of subcutaneous heparin every 8 hours after surgery. At day-3 after the operation, the Color Doppler Ultrasound of the lower extremity and the evaluation of Iliac and Femoral and Popliteal venous system in two sides (bilateral) were performed.Descriptive statistics were reported in this study.

Incidence of DVT after surgery was evaluated in one hundred high-risk patients underwent heparin prophylaxis for one year. Both sides of lower extremity venous Duplex Scan was performed on the third day after surgery operation. Only one case with partial subclinical thrombosis of the right femoral vein was found. Meanwhile, heparin did not have any complications.

Although the study seems to require a larger sample size for more accurate evaluations, given the fact that all patients were considered to be at high risk for DVT, the final result for one-percent of DVT incidence in this statistic community can be extended to larger communities with further studies.
