Aneurysm II: Clinical Manifestations and Diagnostic Studies01:21

Aneurysm 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...
Thoracic Aorta01:15

Thoracic 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,...
Abdominal Aorta01:25

Abdominal 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.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Aneurysm 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...
The Aorta01:14

The 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...
Veins of Thorax01:19

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
The...

Summary

Aortic dissection, a serious condition, can be identified on unenhanced CT scans. A "double aortic lumen" on a thoracic-lumbar CT may indicate dissection, prompting further investigation.

Area of Science:

  • Radiology
  • Cardiovascular Imaging
  • Emergency Medicine

Background:

  • Aortic dissection is a critical medical emergency requiring prompt diagnosis and treatment.
  • Early identification of aortic dissection is crucial for patient outcomes.
  • Computed tomography (CT) is a primary imaging modality for diagnosing aortic pathologies.

Purpose of the Study:

  • To highlight a potential new radiological sign of aortic dissection on unenhanced CT scans.
  • To increase radiologist awareness of subtle CT findings indicative of aortic dissection.
  • To report a case illustrating the detection of type B aortic dissection on unenhanced imaging.

Main Methods:

  • Case presentation of a 71-year-old female patient with hypertension presenting with low back pain.
  • Initial imaging with unenhanced thoracic-lumbar spine CT.
  • Confirmatory diagnosis using enhanced CT scan.

Main Results:

  • Unenhanced thoracic-lumbar spine CT revealed a hyperdense thin line simulating a "double aortic lumen" within the aorta.
  • Enhanced CT scan confirmed the diagnosis of type B aortic dissection.
  • The finding on unenhanced CT was recognized as a potential sign of aortic dissection.

Conclusions:

  • The "double aortic lumen" appearance on unenhanced CT may serve as an early indicator of aortic dissection.
  • Radiologists should consider this finding in the differential diagnosis of aortic abnormalities on non-contrast CT.
  • Increased awareness of this sign can potentially expedite the diagnosis and management of aortic dissection.
