Peripheral Angioplasty
Peripheral Angioplasty is a minimally invasive vascular procedure to open blocked or narrowed arteries in the legs, arms, or pelvis — relieving pain, restoring circulation, and significantly reducing the risk of limb loss without the need for major open surgery.
Overview
Peripheral Angioplasty uses a catheter-based balloon to widen blocked peripheral arteries and restore normal blood flow to the affected limb, treating peripheral artery disease (PAD) that causes pain, poor circulation, and — in severe cases — tissue death and risk of amputation. A stent is often placed after balloon dilation to keep the vessel permanently open and maintain long-term patency. This minimally invasive approach provides immediate improvement in limb blood flow, walking ability, and quality of life, often dramatically transforming a patient's ability to walk and function.
Types of Peripheral Angioplasty
Peripheral angioplasty is tailored to the location and nature of the arterial blockage affecting your circulation. Your vascular specialist will select the most effective approach based on imaging results.
- Iliac Artery Angioplasty (treating blockages in the pelvic arteries)
- Femoral Artery Angioplasty (treating blockages in the main thigh artery)
- Popliteal Artery Angioplasty (targeting the artery behind the knee)
- Below-Knee Angioplasty (tibial and peroneal artery blockages)
- Subclavian or Renal Artery Angioplasty (upper limb or kidney artery intervention)
Risk Factors of Peripheral Artery Disease
Peripheral artery disease shares many risk factors with coronary artery disease, and patients with PAD often have concurrent heart disease. Managing these risks protects both limb and heart health.
- Smoking — the single most significant risk factor for peripheral artery disease
- Diabetes mellitus causing accelerated vascular damage in small and large arteries
- Hypertension increasing stress and plaque formation in peripheral vessels
- High cholesterol promoting atherosclerosis throughout the peripheral arterial system
- Obesity and sedentary lifestyle impairing circulation and vascular health
- Advancing age, particularly over 60 years, with multiple cardiovascular risk factors
Peripheral Artery Disease Symptoms
Peripheral artery disease often progresses silently for years. Recognising warning signs and seeking medical attention promptly can prevent serious complications including limb loss.
- Leg pain, cramping, or heaviness during walking that resolves with rest (intermittent claudication)
- Persistent pain in the foot or toes even at rest in severe cases
- Non-healing wounds or ulcers on the feet, ankles, or lower legs
- Cold or pale skin on one leg or foot compared to the other
- Weak or absent pulse in the foot or behind the knee
- Shiny, hairless skin on the lower leg indicating poor circulation
- Blackening or gangrene of the toes in advanced ischaemia
- Numbness or weakness in the legs during physical activity

Catheter-based vascular procedure that avoids the need for open vascular surgery
Treats multiple arterial blockages in the same session where clinically appropriate
Live fluoroscopic imaging ensures precise balloon and stent positioning
Immediate improvement in limb blood flow and circulation confirmed before discharge
Suitable for blockages in the iliac, femoral, popliteal, and below-knee arteries
Preparation Instructions
- Fast for 4 to 6 hours before the procedure as directed
- Ensure blood tests including CBC, kidney function, and coagulation profile are completed
- Inform your doctor of all medications — blood thinners may need adjustment
- Report any history of allergy to contrast dye or iodine
- Diabetic patients must discuss insulin management on the day of the procedure
- Stop smoking at least 2 weeks before the procedure
- Arrange transportation home as you will not be fit to drive on the day
- Bring all imaging reports including duplex ultrasound or CT angiogram
The Procedure
Step-by-step guide to what you can expect during your peripheral angioplasty procedure.
Vascular Assessment and Planning
Your vascular specialist carefully reviews your symptoms of leg pain, walking difficulty, or non-healing wounds alongside your Doppler ultrasound and CT angiogram to precisely locate the blocked peripheral artery and plan the safest and most effective approach for your angioplasty.
Preparation and Safe Access Setup
Our team confirms your kidney function, allergy history, and medication review before applying local anaesthesia at the catheter entry point — typically the groin or wrist. You remain comfortably awake while our team prepares the access site using a sterile, aseptic technique.
Navigating to the Blocked Vessel
A thin, flexible guidewire is gently advanced through the catheter to the site of the arterial narrowing under continuous X-ray fluoroscopic guidance, allowing your vascular specialist to map the exact location and severity of the blockage before treatment begins.
Balloon Dilation and Stent Placement
The balloon catheter is positioned precisely across the blocked segment and inflated to widen the artery, and a stent is deployed where needed to maintain the vessel's patency long-term. You may feel mild pressure in the treated limb during balloon inflation, which passes quickly.
Confirming Restored Blood Flow
Contrast dye is injected after treatment and fluoroscopic imaging is reviewed to confirm that blood now flows freely through the treated vessel. Your vascular specialist carefully checks all neighbouring vessels to ensure the optimal outcome before the catheter is removed.
Recovery and Limb Care Guidance
Our nursing team monitors your limb circulation, pulse, and insertion site closely in the recovery area before providing you with personalised discharge instructions on antiplatelet medications, walking programme, wound care, and follow-up vascular assessment timing.
What to Expect
Peripheral Angioplasty is performed under local anaesthesia with light sedation so you remain comfortable and relaxed. A catheter is guided to the blocked artery and the balloon is inflated to open the vessel, followed by stent placement if required. The procedure takes 60 to 120 minutes and most patients notice immediate improvement in limb warmth, colour, and walking ability, with discharge within 24 hours.
Recovery
Take all prescribed antiplatelet medications faithfully to prevent the treated artery from re-narrowing, and never stop these without medical advice. Keep the catheter insertion site clean and dry for 24 hours and avoid heavy lifting for 3 to 5 days. Begin gentle walking as soon as your doctor permits — regular walking is one of the most effective ways to maintain good circulation. Return for a follow-up duplex ultrasound at 4 to 6 weeks to confirm the artery remains open.
