Injury of the greater saphenous vein at the lower leg level is typically caused by trauma, such as a fall, or direct contact with a sharp object. It can also be caused by overstretching of the vein or compression due to a cast or other type of immobilization.
Diagnosis of an injury to the greater saphenous vein may be confirmed through physical examination, imaging studies such as ultrasound or CT scan, or by performing a venogram.
Differential diagnosis includes other conditions that may cause similar symptoms, such as deep vein thrombosis, varicose veins, and cellulitis.
Treatment of an injury to the greater saphenous vein may include rest, elevation, and compression stockings. Depending on the severity of the injury, surgery may also be required to repair the vein and restore normal blood flow.
The prognosis of an injury to the greater saphenous vein is generally good. If the injury is treated promptly and correctly, most patients will make a full recovery.
