Insights

Internal carotid artery (ICA) fenestrations are rare anatomical variations. Accurate diagnosis is crucial to prevent misdiagnosis, such as mistaking fenestration for dissection, and ensure appropriate patient management.

Area of Science:

  • Vascular Neurology
  • Radiology
  • Embryology

Background:

  • Anatomical variations of the internal carotid artery (ICA) are uncommon but significant.
  • These variations can impact the diagnosis and prognosis of cerebrovascular diseases.
  • Knowledge of ICA variations aids in preventing unnecessary medical interventions.

Purpose of the Study:

  • To highlight the importance of recognizing internal carotid artery anatomical variations.
  • To present a case of ICA fenestration misdiagnosed as dissection.
  • To discuss the origins and literature of ICA fenestrations.

Main Methods:

  • Case report presentation.
  • Review of diagnostic imaging findings (computed tomography angiography).
  • Literature review on internal carotid artery fenestrations.

Main Results:

  • A case of right cervical internal carotid artery fenestration was identified.
  • The fenestration was initially misdiagnosed as a dissection on computed tomography angiography.
  • The patient received neurological treatment based on the initial misdiagnosis.

Conclusions:

  • Internal carotid artery fenestrations require careful diagnostic evaluation.
  • Misdiagnosis of ICA fenestrations can lead to inappropriate treatment.
  • Understanding embryological origins aids in identifying arterial fenestrations.

Arteries 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...

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...

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...
