Vascular surgery refers to surgical interventions in arteries and veins, as well as conservative therapies for diseases of the peripheral vascular system.
Arteries are blood vessels that take good (oxygenated) blood from heart to other parts of the body whereas veins are blood vessels that bring back impure blood to heart from other parts of the body.
Some of the diseases that can affect blood vessels are:
Veins: In legs they may get dilated resulting in varicose veins. For this, the patient has to wear stockings or crepe bandage and avoid standing for long periods. If there is no relief from discomfort, the patient needs surgery. Another problem is clotting of veins in leg (deep vein thrombosis). This causes severe pain and swelling in legs. This needs immediate doctor’s attention. Surgery is rarely needed for this.
