Arteries of the Head and Neck

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.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck

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...

Overview of the Skull

Overview of the Skull

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Area of Science:

Radiology
Vascular Surgery
Trauma Surgery

Background:

Cerebrovascular injury is a severe complication of craniofacial trauma.
Prompt diagnosis and management are crucial to prevent hemorrhage and rupture.
Interventional radiologists are key in managing these vascular injuries.

Purpose of the Study:

To highlight the role of interventional radiology in managing cerebrovascular injuries from craniofacial trauma.
To emphasize the diagnostic utility of computed tomography angiography.
To outline the effectiveness of endovascular embolization in treating these rare vessel injuries.

Main Methods:

Computed tomography angiography (CTA) for diagnosis.
Angiography for precise identification of vascular lesions.
Endovascular embolization for acute management.

Main Results:

CTA is significant in detecting rare cerebrovascular injuries like carotid-cavernous fistulas, pseudoaneurysms, and arterial lacerations.
Endovascular embolization successfully treats these abnormalities.
Treatment reduces the risk of vessel rupture and associated hemorrhage.

Conclusions:

Interventional radiology is vital for managing cerebrovascular injuries post-craniofacial trauma.
CTA and endovascular embolization are effective diagnostic and therapeutic tools.
Timely intervention prevents severe complications such as hemorrhage.
