Venous cutdown
Venous Cutdown
Venous cutdown is a medical procedure that involves the surgical dissection of a vein, followed by the insertion of a cannula or tube. This procedure is typically performed when a peripheral intravenous cannula cannot be inserted.
Pronunciation
The term 'venous cutdown' is pronounced as /ˈviː.nəs ˈkʌt.daʊn/.
Etymology
The term 'venous cutdown' is derived from the Latin word 'vena', meaning 'vein', and the English word 'cutdown', which refers to the surgical incision made during the procedure.
Procedure
The venous cutdown procedure is typically performed under local anesthesia. The vein is first located, usually the saphenous vein at the ankle or the cephalic vein at the elbow. A small incision is made over the vein, which is then dissected free. A cannula or tube is then inserted into the vein, and the incision is closed.
