Summary
Anatomical variations in aortic arch branching were studied in Jordanians using CT angiography. Approximately 38.8% of patients exhibited variations, with no significant difference between sexes.
Area of Science:
- Anatomy
- Radiology
- Vascular Surgery
Background:
- The aortic arch's branching pattern is crucial for blood supply to the head, neck, and upper limbs.
- Anatomical variations in these branches can impact surgical procedures and diagnostic interpretations.
- Understanding the prevalence of these variations in specific populations is essential for clinical practice.
Purpose of the Study:
- To investigate anatomical variations in the direct branches of the aortic arch in a Jordanian population.
- To determine the prevalence of these variations using contrast Computed Tomography (CT) angiography.
- To analyze the correlation between these variations and patient sex.
Main Methods:
- Analytical, retrospective study of 500 patients (209 females, 291 males).
- Data collected from CT angiography of the aortic arch performed between 2010 and 2014.
- Random sampling method used for patient selection.
Main Results:
- Six distinct patterns of aortic arch artery arrangement were identified in Jordanians.
- The classical branching pattern occurred in 61.2% of cases.
- Anatomical variations accounted for 38.8% of cases, with no significant sex-based correlation (p > 0.05).
Conclusions:
- Significant anatomical variations in aortic arch branching exist within the Jordanian population.
- These findings contribute novel data on the prevalence of aortic arch branching variations.
- Awareness of these variations is critical for angiography, aortic instrumentation, and surgeries of the supra-aortic arteries.

01:10The Arch of Aorta
2.2K
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.

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...

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,...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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.
