Peripheral Angiogram
Home > Services > Peripheral Angiogram
A peripheral angiogram is a minimally invasive diagnostic procedure that uses X-rays and a special contrast dye to evaluate blood flow in the arteries that supply your legs, arms, and other organs outside the heart. When cholesterol plaque builds up in these blood vessels, it can restrict circulation and lead to severe pain, non-healing ulcers, or limited mobility. This imaging test helps pinpoint the exact location and severity of any narrowings or blockages, allowing the doctor to map out the most effective treatment plan to restore healthy blood flow.
1. Indications:
A peripheral angiogram is recommended in patients experiencing symptoms of poor circulation, or when preliminary tests show reduced blood flow. Common indications include:
- Leg pain, cramping, or heaviness while walking (intermittent claudication)
- Pain in the legs or feet at rest due to severe circulation issues
- Non-healing wounds, ulcers, or sores on the lower extremities
- Critical limb ischemia
- Weak or completely absent pulses in the legs or feet
- Coldness, numbness, or tingling in the extremities
- Abnormal non-invasive tests, such as Doppler ultrasound or CT/MR angiogram
- Planning for a therapeutic intervention like angioplasty or stenting
Early and accurate diagnosis through an angiogram is a crucial step in preventing severe complications like tissue damage or limb amputation.
2. Procedure:
A peripheral angiogram is performed in a cath lab under local anesthesia with strict sterile precautions. A small puncture is made in an artery, usually in the groin (femoral artery), though the wrist (radial artery) is sometimes used depending on the area being evaluated.
Through this puncture, a thin, flexible catheter is inserted and guided to the area of interest using X-ray imaging. Once the catheter is in position, a contrast dye is injected into the blood vessels. This dye makes the arteries clearly visible on the monitors, instantly highlighting any narrowed, blocked, or damaged segments. You may feel a brief, warm flush spreading through your body as the dye is injected, which is completely normal.
If a significant blockage is found during the angiogram, the doctor may treat it immediately during the same session using balloon angioplasty and stenting. The diagnostic angiogram usually takes 30 to 60 minutes depending on the complexity.
3. Safety:
Peripheral angiograms are highly safe diagnostic procedures when performed by experienced interventional specialists in a well-equipped cath lab. Continuous monitoring of heart rate, blood pressure, and oxygen levels is done throughout the procedure.
Possible but uncommon risks include:
- Bleeding or hematoma at the puncture site
- Vessel injury or dissection
- Contrast allergy
- Kidney function changes
- Clot formation or embolism
- Infection at the insertion site
