Summary
The 125I-fibrinogen test effectively detects asymptomatic postoperative deep venous thrombosis (DVT). Doppler ultrasound is useful for identifying symptomatic DVT extending above the knee.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Thrombosis Research
Background:
- Postoperative deep venous thrombosis (DVT) is a significant complication following abdominal surgery.
- Early detection of DVT is crucial to prevent potentially life-threatening pulmonary embolism.
Purpose of the Study:
- To evaluate the efficacy of 125I-fibrinogen testing and Doppler ultrasonic examination in detecting postoperative deep venous thrombosis (DVT) of the lower limbs.
- To compare the diagnostic capabilities of these methods for asymptomatic and symptomatic DVT.
Main Methods:
- Systematic performance of 125I-fibrinogen tests and Doppler ultrasonic examinations in 227 patients undergoing abdominal surgery.
- Venography and lung scanning were utilized for confirmation of DVT and pulmonary embolism, respectively.
Main Results:
- The 125I-fibrinogen test identified 19 patients with potential DVT, confirmed by venography in 18 cases (16 calf, 2 femoral).
- Five pulmonary embolisms were detected; venography revealed DVT in 4 of these patients.
- Doppler ultrasound detected abnormalities in 4 of the 18 confirmed DVT cases, specifically the 2 femoral DVT.
Conclusions:
- The 125I-fibrinogen test is a valuable tool for detecting asymptomatic postoperative deep venous thrombosis (DVT).
- Doppler ultrasonic examination is more effective in identifying clinically symptomatic DVT with proximal extension (above the knee).
