Vascular bypass
Vascular Bypass
Vascular bypass or blood vessel bypass is a surgical procedure performed to redirect blood flow from one area to another by reconnecting blood vessels. This is often done to bypass a diseased or blocked area to improve blood flow.
Pronunciation
Vascular: /ˈvæskjʊlər/ Bypass: /ˈbaɪˌpæs/
Etymology
The term "vascular" originates from the Latin word "vasculum" meaning "small vessel". The term "bypass" comes from the English language, meaning "to avoid something by going around it".
Procedure
The vascular surgeon removes a healthy blood vessel, often from the patient's own leg, to use as a graft. This graft is then used to reroute blood around the blocked or narrowed artery. The procedure is performed under general anesthesia.
