Vascular Surgery

Vascular surgery is now considered a specialty in its own right.  It is a specialty of surgery in which diseases of the vascular system or arteries and veins, are managed by medical therapy, minimally-invasive catheter procedures, and surgical reconstruction. The vascular surgeon is trained in the diagnosis and management of diseases affecting all parts of the vascular system except that of the heart and brain which are dealt with by the cardiothoracic surgeons and neurosurgeons respectively.

Common conditions requiring the expertise of vascular surgeons include:

·         Aortic Aneurysm

This is a localised dilatation (ballooning) of the aorta exceeding the normal diameter by more than 50 percent. Most of these occur in the abdominal aorta. Elderly men who smoke or are hypertensive are more at risk. The major complication of abdominal aortic aneurysms is rupture, which can be life-threatening as large amounts of blood spill into the abdominal cavity and can lead to death within minutes.

·         Carotid Stenosis

It is a narrowing or constriction of the inner surface (lumen) of the carotid artery, usually caused by build-up of fatty material such as cholesterol and predispose to stroke.

·         Varicose Veins

Varicose veins commonly refer to enlarged and tortuous veins and most commonly occurs on the leg. They are unsightly, cause aching, impair healing of leg wounds and even cause spontaneous ulceration.

·         Peripheral Vascular Disease (PVD)

The obstruction of large peripheral arteries is called PVD, commonly referred to as peripheral arterial disease (PAD) or peripheral artery occlusive disease (PAOD).  This is a result of atherosclerosis, inflammatory processes leading to narrowing, embolism, or thrombus formation. It leads to acute or chronic ischemia (lack of blood supply). Most commonly, PVD affects arteries in the lower extremity.

PVD also includes a subset of diseases classified as microvascular diseases resulting from episodal narrowing of the arteries (Raynaud's phenomenon), or widening thereof (erythromelalgia), i.e. vascular spasms.

·         Acute Limb Ischaemia

When there is a lack of blood flow to a limb,acute limb ischaemia occurs.  It is usually due to either an embolism or thrombosis of an artery in those with underlying peripheral vascular disease.  It is a highly treatable condition with proper surgical care but may lead to limb amputation in severe cases.

·         Aortic Dissection

When a tear in the inner wall of the aorta causes blood to flow between the layers of the wall of the aorta and force the layers apart,aortic dissection occurs.  This is a medical emergency and can quickly lead to death, even with optimal treatment.  If the dissection tears the aorta completely open (through all three layers), massive and rapid blood loss occurs. Aortic dissections resulting in rupture have an 80% mortality rate and 50% of patients die before they even reach the hospital.
