Conclusion:
The internal jugular vein is crucial in intensive care units and head
and neck surgeries. Handling the internal jugular vein without
considering anatomical variances is fatal. Early detection of these
anomalies allows for necessary measures to avoid patient injury (e.g.,
discussions with the patient and surgeons about ideal solution
anesthetics plans, cannulation sites, monitoring tactics, and thus
further inquiry prior to operation). The most common headache symptom is
usually caused by that benign, and it can generally be detected after a
comprehensive history and targeted neurologic and overall physical
tests. Headache caused by cerebral venous abnormalities is a new issue
that all health care workers should be aware of this issue.
