Peripheral artery disease (PAD) affects millions of people, causing blocked or severely narrowed arteries in the legs that reduce blood flow, cause pain on walking, and in severe cases threaten limb viability. For decades, the only option for significant arterial blockages was open bypass surgery — a major operation requiring general anaesthesia and a prolonged recovery. Today, the majority of peripheral arterial blockages can be treated with balloon angioplasty and stenting — a minimally invasive catheter-based procedure that restores blood flow without a single major incision. Dr. Mohamed Haggag performs peripheral angioplasty at his vascular surgery practice in Heliopolis, Cairo.

What Is Peripheral Angioplasty?

Percutaneous transluminal angioplasty (PTA) is performed using a thin, flexible catheter inserted through a small needle puncture — usually in the groin or wrist. Under X-ray guidance (fluoroscopy), the catheter is guided through the arterial system to the site of the blockage. A small balloon at the tip of the catheter is then inflated to compress the plaque against the artery wall and re-establish a clear channel for blood flow.

When the balloon alone does not achieve an adequate result — due to elastic recoil or residual narrowing — a metallic stent (a small mesh tube) is deployed at the treated site to hold the artery open permanently. Drug-eluting stents coated with medications that prevent restenosis (re-narrowing) are used in specific anatomical locations.

Which Arteries Can Be Treated?

  • Iliac arteries (pelvis): Excellent results — high patency rates, often the first choice over bypass
  • Femoral artery (thigh): Most commonly affected in PAD. Good results for short occlusions; longer lesions may require drug-coated balloons or stents
  • Popliteal artery (behind the knee): Treated, but stent placement here is avoided due to the flexion forces on the artery
  • Below-knee arteries (tibial and peroneal): Critical for diabetic foot wound healing — angioplasty restores perfusion to the foot, enabling ulcer healing
  • Renal arteries: For renovascular hypertension (see renal vascular disease article)

⚠️ Critical Limb Ischaemia Requires Urgent Intervention

Rest pain, non-healing wounds, or black discolouration of a toe are signs of critical limb ischaemia — a medical emergency. Without urgent revascularisation, major amputation within weeks is the likely outcome. If you or a family member has these symptoms, contact Dr. Haggag immediately or go to an emergency vascular unit.

The Procedure: Step by Step

  1. Pre-procedure CT angiography maps the arterial anatomy and plans the approach
  2. Local anaesthesia at the access site — no general anaesthesia required
  3. Arterial access by needle puncture, then a sheath is inserted
  4. Catheter and guidewire navigated across the blockage under X-ray
  5. Balloon inflated for 1–3 minutes; result checked by angiogram
  6. Stent deployed if needed
  7. Sheath removed and pressure applied to the puncture site
  8. Most patients walk within a few hours and are discharged the same day or next morning

✅ After Angioplasty — What Happens Next?

Dual antiplatelet therapy (usually aspirin plus clopidogrel) is prescribed for 1–3 months after stent placement to prevent clotting. Statins and risk factor modification are essential for long-term patency. A Doppler follow-up at 3 and 12 months monitors the treated segment for restenosis. Most patients experience immediate symptomatic improvement — they can walk further without pain from the day after the procedure.
