Summary
A rare vascular ring involving a right cervical aortic arch and aberrant left subclavian artery can be diagnosed with advanced imaging. Surgical intervention is effective for treating this congenital anomaly in both infants and adults.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Radiology
Background:
- Vascular rings are congenital anomalies of the aortic arch.
- A right cervical aortic arch with aberrant retroesophageal left subclavian artery and ligamentum arteriosum is a rare variant.
- Kommerell's diverticulum can be associated with these anomalies.
Observation:
- Two patients, a 21-day-old infant and a 54-year-old adult, presented with symptoms of a rare vascular ring.
- Diagnosis was confirmed using multislice 3-dimensional computed tomography and magnetic resonance imaging.
- The adult patient had an associated Kommerell's aneurysm.
Findings:
- Both patients underwent successful surgical division of the vascular ring.
- The infant's vascular ring was completely divided.
- The adult required resection of the Kommerell's aneurysm and reimplantation of the aberrant subclavian artery.
Implications:
- This rare vascular ring can be effectively diagnosed with modern imaging techniques.
- Surgical management is crucial for relieving symptoms and preventing complications.
- Complex cases, like the adult with Kommerell's aneurysm, necessitate tailored surgical approaches.

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.

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...

01:15Thoracic Aorta
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,...
01:25Abdominal Aorta
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.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:14The Aorta
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
