Arterial and Venous Doppler (Both Lower limb)

You should get an arterial and venous Doppler of both legs if you have leg pain while walking, cold or numb feet, non-healing wounds, leg swelling, visible varicose veins, skin discoloration, or leg ulcers. It is also recommended for people with diabetes, smoking habits, or high cholesterol. Sudden painful swelling of one leg needs urgent testing for DVT.

No special preparation or fasting is required for an arterial and venous Doppler of both legs. Wear loose clothing or shorts for easy access to your legs, and remove compression stockings before the scan. Avoid smoking for at least 2 hours beforehand, as it narrows blood vessels. Continue your regular medicines and bring previous reports.

No, fasting is not required for an arterial and venous Doppler of both lower limbs. You can eat and drink normally and take your regular medicines before the scan. Wear loose clothing, avoid smoking for at least 2 hours beforehand, and remove compression stockings before the test.
