Summary
Aortic dissection originating from an aberrant right subclavian artery was successfully treated with endovascular repair. This approach sealed the entry site, leading to favorable healing and thrombosis of the false lumen.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Medical Imaging
Background:
- Aortic dissection is a life-threatening condition often involving the ascending aorta.
- Aberrant right subclavian artery is a rare congenital anomaly of the aortic arch.
- An intimal tear in an aberrant vessel can be a rare cause of aortic dissection.
Observation:
- A 47-year-old male presented with aortic dissection.
- Intraoperative arteriography revealed an aortic arch anomaly: a common carotid trunk and an aberrant right subclavian artery.
- The intimal tear originated in the aberrant right subclavian artery, with retrograde and anterograde extension of the dissection.
Findings:
- Endovascular repair using a Wallgraft endoprosthesis successfully sealed the entry site in the aberrant right subclavian artery.
- Follow-up computed tomography confirmed satisfactory healing and complete thrombosis of the proximal false lumen.
Implications:
- Endovascular treatment is a viable option for aortic dissection originating from aberrant subclavian arteries.
- Accurate diagnosis of aortic arch anomalies is crucial for managing complex aortic dissections.
- This case highlights the importance of considering rare anatomical variations in aortic pathology management.

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.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:25Abdominal 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.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
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...

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,...
