What is Vascular lab?
A vascular lab is a specialized medical facility focused on diagnosing and managing disorders of the blood vessels, including arteries and veins. Using advanced imaging techniques like ultrasound, Doppler studies, and other non-invasive methods, vascular labs evaluate blood flow, detect blockages, and monitor conditions such as varicose veins or peripheral artery disease. These assessments help guide treatment plans and ensure optimal vascular health.
ABI (Ankle Brachial Index Test)
The Ankle-Brachial Index (ABI) test is a simple, non-invasive diagnostic tool used to assess blood flow and detect peripheral artery disease (PAD). During the test, blood pressure measurements are taken at both the ankle and the arm. The ABI is calculated by dividing the blood pressure in the ankle by the blood pressure in the arm. A lower ABI indicates reduced blood flow to the legs, which can be a sign of arterial blockages or other vascular issues.
- Color Doppler/Ultrasound of vein: Color Doppler test helps in the diagnosis of varicose veins, deep vein thrombosis (DVT).
- Color Doppler/Ultrasound of peripheral arteries: This is a basic test to confirm arterial blood supply to the peripheral organs like upper and lower limbs.
- Carotid Color Doppler: Carotid Doppler is specifically meant for assessment of blood vessels that supply the brain. Carotid arteries are the major vessels which carry blood to the brain.
- Dialysis access evaluation ultrasound: This ultrasound helps in evaluating the diameter and condition of veins of upper limb which are commonly used for dialysis access fistula.
Color Doppler
CT Angiography
CT Angiography (CT guided non-invasive angiography) is a highly confirmatory test and helps in exact treatment and management plan. By this test, we can evaluate the exact site, extent, and type of blockages, as well as the size of blood vessels (we can decide whether blockages can be treated by angioplasty or will require a peripheral bypass). This provides a road map which helps us keep planning further treatment.
MRI (Magnetic Resonance Imaging)
This test is highly useful for diagnosis of vascular malformation. It can help to know the extent of the lesion.
DSA (Digital Subtraction Angiography)
An invasive but accurate technique which is useful for diagnosis, especially in a diabetic patient who have calcified arteries.
