Vascular (blood vessel) disorders treated by general surgery at WDHB include 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.

All other vascular problems are dealt with by Auckland City Hospital.
