Summary
A rare case of bilateral thyroid ima arteries (TIAs) originating from the brachiocephalic trunk was identified during thyroid surgery. This vascular anomaly underscores the need for meticulous surgical planning to prevent complications.
Area of Science:
- Vascular anatomy
- Surgical oncology
- Radiology
Background:
- Bilateral thyroid ima arteries (TIAs) originating from the brachiocephalic trunk are exceptionally rare.
- Identifying such vascular anomalies is critical for successful thyroid and mediastinal surgeries.
- Failure to recognize these variations can lead to significant intraoperative complications.
Observation:
- A 28-year-old female underwent surgery for a thyroid nodule.
- Intraoperative findings revealed two unexpected arteries from the brachiocephalic trunk.
- Postoperative imaging and 3D reconstruction confirmed these as bilateral TIAs.
Findings:
- The patient underwent total thyroidectomy, bilateral neck dissection, and mediastinal lymph node dissection.
- The identified bilateral TIAs were carefully preserved during the procedures.
- The patient experienced an uneventful recovery with no complications.
Implications:
- This case emphasizes the importance of thorough intraoperative assessment and advanced imaging in surgical planning.
- Awareness of rare vascular variations like bilateral TIAs is crucial for minimizing surgical risks.
- This report contributes valuable insights into vascular anatomy and its clinical significance in surgical practice.

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.

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 thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
