For what condition is temporary artery ligation performed?

• A. To manage severe headache
• B. To control bleeding
• C. To decrease vascular pressure
• D. To assist in biopsy

Answer: (B)

Temporary artery ligation is primarily performed to control bleeding. When a major artery is severed or there is significant blood loss, ligating the artery can help to temporarily stop the flow of blood, allowing time for further medical intervention or stabilization of the patient. This procedure is crucial in trauma situations where immediate blood loss poses a risk to the patient's life, and it serves as a means of providing temporary control until more definitive surgical repair can be performed.

Managing severe headaches, decreasing vascular pressure, or assisting in biopsy are not the main objectives of temporary artery ligation. While vascular pressure may be a concern in some contexts, the ligation serves a more immediate function in bleeding control rather than serving as a long-term solution for vascular pressure management. Similarly, while biopsies may involve the examination of blood vessels, ligation is not a standard step in that procedure.
