Contiguous internal carotid arteries in empty sella syndrome
Radiology
|July 1, 1976
Summary
This study reports a unique case of nearly contiguous internal carotid arteries in empty sella syndrome. Carotid angiography can diagnose this rare condition, especially with a large sella turcica.
Area of Science:
- Neurology
- Vascular Anatomy
Background:
- Empty sella syndrome is a condition where the pituitary gland shrinks or collapses.
- The cavernous internal carotid arteries are major blood vessels supplying the brain.
Observation:
- A patient with empty sella syndrome presented with unusually close proximity of the right and left cavernous internal carotid arteries.
- This anatomical variation was considered unique based on existing literature and measurements.
Findings:
- The proximity of the cavernous internal carotid arteries in this case was significantly greater than previously reported.
- This unique anatomical finding highlights potential variations in vascular structures associated with empty sella syndrome.
Implications:
- Carotid angiography is a valuable diagnostic tool for identifying this rare presentation of empty sella syndrome.
- Understanding such anatomical variations is crucial for neurosurgical and radiological assessments.
- Further research may elucidate the relationship between empty sella syndrome and internal carotid artery anatomy.

The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.

Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
