Insights

Coarctation of the aorta with type B aortic dissection is rare. This case highlights 64-multidetector row computed tomography (MDCT) as crucial for diagnosing this unusual presentation and planning surgical repair.

Area of Science:

  • Cardiovascular Medicine
  • Radiology
  • Medical Imaging

Background:

  • Coarctation of the aorta (CoA) is a congenital narrowing of the aorta.
  • Aortic dissection (AD) is a tear in the inner layer of the aorta.
  • CoA with AD is uncommon, particularly type B AD, with few reported cases globally.

Observation:

  • A 36-year-old male presented with sudden chest and back pain.
  • The patient exhibited highly developed collateral circulation.
  • 64-multidetector row computed tomography (MDCT) revealed coarctation of the aorta with type B aortic dissection and collaterals.

Findings:

  • MDCT with 3D image reconstruction accurately depicted the anatomical relationship between CoA, collaterals, and type B AD.
  • The findings suggest that developed collaterals may have masked symptoms of CoA and AD.
  • MDCT provided superior information for surgical planning compared to cardiac catheterization.

Implications:

  • This case underscores the importance of advanced imaging in diagnosing rare cardiovascular conditions.
  • MDCT is a valuable tool for assessing complex anatomical variations in CoA with AD.
  • Accurate pre-operative imaging is essential for successful surgical management of coarctation of the aorta with aortic dissection.

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...

The Arch of Aorta01:10

The 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.
Encircling the heart, the coronary arteries form a ring-like structure before...

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...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla01:27

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
