Summary
We report two cases of aberrant innominate artery (IA) in the neck. Surgical imaging revealed the IA anterior to the airway, highlighting significant risks for cervical surgeries in such anatomical variations.
Area of Science:
- Vascular Surgery
- Anatomical Variations
- Surgical Risk Assessment
Background:
- The innominate artery (IA), or brachiocephalic trunk, is a major artery originating from the aortic arch.
- Aberrant IA positioning can lead to diagnostic and surgical challenges.
Observation:
- Two distinct cases of IA presenting in an unusual cervical position were identified.
- In one case, surgical imaging demonstrated the IA and its branches positioned anterior to the laryngotracheal axis.
Findings:
- The anatomical variation of a cervical innominate artery was confirmed in two patients.
- Surgical visualization provided detailed anatomical context of the aberrant IA relative to the airway.
Implications:
- Cervical surgeries in patients with a cervical IA carry a substantial risk of vascular injury.
- Awareness of this anatomical anomaly is crucial for pre-operative planning and patient safety in head and neck procedures.

01:26Arteries 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...

01:22Aneurysm IV: Nursing Management
Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:10The 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.
Encircling the heart, the coronary arteries form a ring-like structure before...

01:19Veins 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...
