Vascular conditions treated:

Abdominal Aortic Aneurysm

An enlargement of the aorta, the main blood vessel that delivers blood to the body, at the level of the abdomen.

An abdominal aortic aneurysm (AAA) can be life-threatening if it bursts. Abdominal aortic aneurysms are most common in older men and smokers.

We treat the condition with minimally invasive surgery using endovascular stents. The procedure can be performed under local anaesthetic.

Peripheral arterial disease

A circulatory condition in which narrowed blood vessels reduce blood flow to the limbs.

Peripheral vascular disease is a sign of fatty deposits and calcium building up in the walls of the arteries (atherosclerosis). Risk factors include ageing, diabetes and smoking.

We treat the condition using endovascular techniques to open up arteries and improve distal circulation. Bypass surgery in the leg is usually performed as last resort.

Carotid artery disease

Narrowing of the blood vessels in the neck that carry blood from the heart to the brain.

Carotid artery stenosis can be caused by cholesterol build-up in the blood vessels (atherosclerosis). Blood clots can form in this area and travel up to the brain causing stroke.

We treat this using open surgery under a general anaesthetic. Stents are not preferred in this position given the risk of embolisation.

Leg Ulcers

Leg ulcers are open wounds on your leg that take more than two weeks to heal despite treatment. These ulcers typically appear between the ankle and knee.

We treat them with improving the blood supply to the leg using minimally invasive techniques and controlling the oedema and inflammation with compression. 

Varicose veins

Gnarled, enlarged veins, most commonly appearing in the legs and feet.

Varicose veins are generally benign. The cause of this condition is not known.

We treat them either conservatively or with myriad of techniques including open surgery, injections or laser.

Mesenteric vascular disease

Mesenteric artery ischemia occurs when there is a narrowing or blockage of one or more of the three major arteries that supply the small and large intestines.

We treat this with minimally invasive techniques using stents to open the arteries. Bypass surgery may rarely be performed.

Renal artery disease

Renal artery stenosis (RAS) occurs when the arteries that carry blood to your kidneys narrow. It's usually the result of atherosclerosis. It causes difficult to treat high blood pressure.

We treat this with minimally invasive surgery using stents in the renal artery. Bypass surgery is rarely necessary.

Popliteal artery aneurysm

Popliteal artery aneurysms are the most common peripheral arterial aneurysm and the second most common aneurysm after abdominal aortic aneurysms. They cause embolism to the small arteries in the calf and can cause gangrene in the leg.

We treat them again using minimally invasive surgery using stents. Sometimes bypass surgery is necessary.

Thoracic Outlet Syndrome

A group of disorders that occur when certain blood vessels or nerves are compressed.

Thoracic outlet syndrome affects the space between the collarbone and first rib (thoracic outlet). Common causes include trauma, repetitive injuries, pregnancy and anatomical defects, such as having an extra rib.

90% of the time the condition requires no operative management including adjustment to posture and physio therapy. When aneurysms develop, invasive treatments are recommended.

Pelvic Congestion Syndrome

Pelvic congestion syndrome is a condition that causes chronic pelvic pain. It's thought to be caused by problems with the veins in the pelvic area.

We investigate this using non invasive imaging and manage it using minimally invasive techniques such as coils introduced to the pelvic veins via the neck.
