Vascular (blood vessel) disorders treated by vascular surgery include varicose veins, blockages and narrowings in the arteries or abnormal swellings of the arteries (aneurysm).

The most common of these venous conditions facing the vascular surgeon is varicose veins. This occurs when veins in the legs and thighs become enlarged and twisted. This is often caused by the failure of the one-way valve system in the veins, in which case it can be treated surgically by removing the segments of veins containing the malfunctioning valves as well as those veins which are significantly dilated.

Arterial problems can be due to blockages, narrowings or dilatations (swellings). Treatment for each problem, depends on the site of the artery and the underlying pathology. Patients medical condition will be taken into consideration when offering treatment options. New endovascular treatments are also available depending on the suitability of the artery, situation and pathology.
