Angioplasty: Restoring Blood Flow Safely and Effectively in Dubai
Introduction
Angioplasty is a minimally invasive procedure that restores blood flow through narrowed or blocked arteries. It is commonly used to treat Peripheral Artery Disease (PAD), coronary artery disease, and vascular blockages affecting the legs, kidneys, or other parts of the body. By reopening the arteries and improving circulation, angioplasty helps relieve pain, promote wound healing, and prevent tissue loss or amputation in advanced cases.
​
Performed under local or general anaestheisa and guided by live imaging, angioplasty offers a safe and effective alternative to open surgery, allowing for faster recovery and shorter hospital stays.
In Dubai, Dr. Soroush Sohrabi, a UK-trained Consultant Vascular & Endovascular Surgeon with international fellowships in the US and Australia, provides expert angioplasty treatment using advanced endovascular techniques to help patients regain mobility and improve vascular health.
What Is Angioplasty?
Angioplasty (also called percutaneous transluminal angioplasty or PTA) is a procedure designed to widen narrowed arteries caused by plaque buildup (atherosclerosis). A small balloon is inserted through a thin tube (catheter) and inflated inside the artery to open the blockage. In many cases, a stent—a tiny mesh tube—is then placed to keep the artery open.
​
The goal of angioplasty is to restore normal blood flow to the affected area, relieving symptoms such as leg pain, cramping, or non-healing ulcers, and reducing the risk of severe complications like critical limb ischaemia.
Conditions Treated with Angioplasty
Angioplasty is commonly performed for:
​
-
Peripheral Artery Disease (PAD) — blockages in the leg arteries causing pain or tissue loss.
-
Renal Artery Stenosis — to improve kidney function and blood pressure control.
-
Diabetic Foot and Non-healing Ulcers — to improve circulation and promote wound healing.
-
Critical Limb Ischaemia (CLI) — severe arterial blockage or narrowing causing rest pain or gangrene.
-
Intermittent Claudication - arterial or narrowing causing leg pain on activity.
Symptoms That May Indicate the Need for Angioplasty
Patients may benefit from angioplasty if they experience:
-
Pain, cramping, or fatigue in the legs when walking (intermittent claudication)
-
Cold, pale, or discoloured feet
-
Weak or absent pulses in the legs
-
Numbness, tingling, or skin changes due to poor blood flow
How Angioplasty Works
-
Access: A small puncture is made, usually in the groin or wrist, to insert a catheter into the artery.
-
Imaging: A special dye (contrast) is injected, and real-time X-ray imaging (angiography) identifies the blocked area.
-
Balloon Inflation: A fine balloon is advanced into the blockage and gently inflated to stretch the artery open.
-
Stent Placement: In many cases, a stent is inserted to keep the artery open long-term.
-
Completion Check: The catheter is removed once blood flow is restored, and the puncture site is sealed.
​
The procedure typically takes 30–90 minutes, and most patients are able to walk within a few hours and return home the same or next day.
Risks and Complications
Angioplasty is generally very safe, but like all medical procedures, it carries some risks. These may include:
-
Bleeding or bruising at the puncture site
-
Re-narrowing of the artery (restenosis)
-
Formation of a blood clot
-
Vessel injury or spasm
-
Allergic reaction to contrast dye
​
The overall risk is low, especially when performed by an experienced vascular and endovascular specialist.
Recovery and Aftercare
Most patients go home the same or next day. It is normal to feel mild bruising or soreness at the access site. After angioplasty, it is important to:
-
Take antiplatelet medications (e.g., aspirin or clopidogrel) if prescribed by your physician to prevent clots.
-
Control risk factors such as smoking, diabetes, and high cholesterol.
-
Attend follow-up scans to monitor stent or artery patency.
​
Long-term success depends on a combination of effective treatment and healthy lifestyle changes.
Frequently Asked Questions (FAQ)
Q: What conditions can angioplasty treat?
A: Angioplasty is most commonly performed for peripheral artery disease (PAD), intermittent claudication, critical limb ischaemia, renal artery stenosis, and to improve circulation in diabetic foot disease with non-healing ulcers.
Q: How long does angioplasty take, and will I need to stay in hospital?
A: The procedure typically takes 30 to 90 minutes. Most patients are able to walk within a few hours and return home the same day or the next day.
Q: Is angioplasty painful?
A: The catheter is inserted through a small puncture in the groin or wrist under local or general anaesthesia, so discomfort during the procedure is minimal. Mild bruising at the puncture site is common afterwards and usually settles within days.
Q: Will I need a stent as well as the balloon?
A: In many cases a stent is placed after balloon inflation to keep the artery open long-term. Whether one is needed depends on the location of the blockage and how the artery responds to the balloon.
Q: What are the risks of angioplasty?
A: Angioplasty is generally very safe. Possible risks include bleeding or bruising at the puncture site, re-narrowing of the artery (restenosis), blood clot formation, vessel injury or spasm, and allergic reaction to the contrast dye.
