Peripheral Angiography and Intervention
What the Service Involves
Peripheral angiography involves using X-ray imaging to visualize blood flow in the peripheral arteries. Similar to a coronary angiogram, this procedure uses a catheter to inject a contrast dye into the blood vessels. If a blockage or narrowing is identified, various interventions such as angioplasty or stenting may be performed to restore adequate blood flow.
Preparation
Patients are advised to fast for several hours before the procedure and may need to adjust their regular medications, especially blood thinners, as directed by the physician.
During the Test
The procedure typically lasts about an hour but can vary depending on whether interventions are performed during the same session. Local anesthesia is administered, and patients are usually awake but sedated to ensure comfort.
Benefits
Peripheral angiography and intervention can significantly improve blood flow, reduce symptoms like leg pain during walking, and prevent more severe outcomes such as limb loss in advanced cases.
