What a vascular surgeon does — roles scope and when you need one — Dr Rahul Agarwal CARE Hospitals

“A vascular surgeon is the specialist your body calls when blood cannot flow freely — whether that means opening a blocked artery, repairing a ruptured aorta, or creating a lifeline for dialysis.”

When a doctor refers you to a vascular surgeon, it can feel like stepping into unfamiliar territory. Most people understand what a cardiologist does, or what an orthopaedic surgeon fixes — but vascular surgery sits in a quieter corner of medicine, even though it deals with some of the most life-critical structures in the human body.

I want to change that. In this article, I will explain exactly what a vascular surgeon does, what conditions we treat, what the difference is between open and endovascular surgery, and most importantly — when you should see one.


🫀 The Simple Answer

A vascular surgeon is a doctor who specialises in treating diseases of the blood vessels — specifically the arteries, veins, and lymphatic system — throughout the body. We treat everything from leg artery blockages (peripheral artery disease) and dangerous aortic bulges (aneurysms) to varicose veins, blood clots in the legs, and dialysis access surgery for kidney patients.

We do not treat the blood vessels of the heart (that is a cardiac surgeon’s domain) or the major brain arteries directly (that is a neurosurgeon). Every other blood vessel in the body — from the aorta to the arteries in your feet — falls within our scope.


🔬 What Makes Vascular Surgery Unique?

The defining feature of modern vascular surgery is that we use two very different toolkits — and often combine them in the same patient.

Open surgery involves directly exposing the blood vessel through an incision, removing or repairing the problem with the surgeon’s hands. This is the traditional approach — more invasive, but sometimes the only option or the best option for certain conditions.

Endovascular surgery involves working entirely inside the blood vessel through a tiny puncture in the skin. We thread catheters, balloons, stents, and stent-grafts through the vessel under X-ray guidance. Most patients go home the next day with just a small dressing over the puncture site.

The ability to offer both — and to judge which approach is right for each patient — is what makes a fully trained vascular surgeon different from an interventional radiologist (who only does endovascular) or a general surgeon (who rarely trains in vascular techniques).


🦠 Conditions a Vascular Surgeon Treats

Arterial Diseases

  • Peripheral Artery Disease (PAD) — Blocked or narrowed arteries in the legs, causing pain while walking, non-healing wounds, and in severe cases, the risk of amputation
  • Aortic Aneurysm — A dangerous balloon-like bulge in the aorta (the body’s main artery) that can be fatal if it ruptures
  • Carotid Artery Disease — Plaque buildup in the neck arteries that supply the brain, causing stroke risk
  • Acute Limb Ischaemia — A sudden, complete blockage of a limb artery that constitutes a vascular emergency
  • Mesenteric Ischaemia — Insufficient blood supply to the intestines

Venous Diseases

  • Varicose Veins — Enlarged, twisted leg veins causing pain, swelling, and skin breakdown
  • Deep Vein Thrombosis (DVT) — Blood clots in the deep veins of the legs or pelvis
  • Chronic Venous Insufficiency — Long-term valve failure in leg veins leading to swelling, ulcers, and skin changes
  • Lymphoedema — Persistent limb swelling due to lymphatic damage

Dialysis Access

  • AV Fistula Creation — Connecting an artery and vein in the arm to create permanent haemodialysis access
  • AV Graft Placement — A synthetic bridge used when native veins are not suitable
  • Tunnelled Dialysis Catheter — Temporary central line access for urgent dialysis

Diabetic & Limb-Threatening Conditions

  • Diabetic Foot Disease — Non-healing ulcers and gangrene due to poor circulation, requiring revascularisation and wound care
  • Critical Limb Ischaemia (CLI) — Severe arterial blockage threatening limb loss
  • Thoracic Outlet Syndrome — Compression of vessels and nerves at the junction of neck and chest

🏥 When Should You See a Vascular Surgeon?

Most patients arrive through a referral from their family doctor, cardiologist, or nephrologist. But there are situations where you should ask for a vascular surgery opinion directly. Seek one if you have:

  • Leg pain or cramping that comes on with walking and disappears with rest (claudication)
  • A wound or ulcer on the leg or foot that is not healing after several weeks
  • Varicose veins with pain, skin changes, or bleeding
  • A pulsating, tender lump in the abdomen
  • A sudden cold, blue, or painful limb
  • Kidney failure requiring dialysis access planning
  • Diabetes with foot complications

❓ Frequently Asked Questions

Is a vascular surgeon the same as a cardiologist?

No. A cardiologist treats heart disease medically (with medications, stents in coronary arteries, pacemakers). A cardiac surgeon operates on the heart. A vascular surgeon operates on all peripheral arteries, veins, and the aorta — but not the coronary arteries or heart valves.

Do I need a referral to see a vascular surgeon?

In India, you can self-refer to a vascular surgeon for a consultation. However, most patients are referred by a family physician, nephrologist, diabetologist, or cardiologist who has identified a vascular problem requiring specialist opinion.

What happens at a first vascular surgery consultation?

Your surgeon will take a detailed history of your symptoms, examine your pulses and circulation, and usually arrange a vascular ultrasound or other imaging to assess your blood vessels before recommending a treatment plan.


💡 Key Insight: Vascular disease is often silent until it becomes critical. Leg pain while walking, wounds that won’t heal, or a pulsating belly lump are never symptoms to ignore. A single vascular consultation can be the difference between keeping a limb and losing it.
