Summary
Doppler ultrasound accurately maps venous reflux in varicose veins, identifying specific escape points. This precise mapping allows for targeted therapy, avoiding unnecessary surgical stripping of the saphenous system.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Medical Ultrasound
Background:
- Primary varicose veins present with diverse clinical manifestations.
- Identifying the precise source of venous reflux is crucial for effective treatment.
Purpose of the Study:
- To correlate clinical presentations of primary varicose veins with their topographic and anatomic reflux sources.
- To evaluate the diagnostic utility of Doppler ultrasound in mapping venous reflux.
Main Methods:
- One hundred sixty-three patients with primary varicose veins underwent examination.
- Doppler ultrasound was used to trace the origin and extent of venous reflux.
- Patients were categorized into three groups based on reflux patterns.
Main Results:
- Typical saphenous varicosities with junctional escapes (SFJ/SPJ incompetence) occurred in 71.3% of limbs.
- Atypical saphenous varicosities with non-junctional escapes (perforator incompetence) occurred in 22.17% of limbs.
- Non-saphenous varicosities were observed in 6.52% of limbs.
Conclusions:
- Physical examination alone may lead to unnecessary surgical interventions.
- Doppler ultrasound is essential for accurately mapping venous reflux.
- Hemodynamic information from Doppler US enables selective, multimodal therapy, avoiding indiscriminate saphenous vein stripping.
