Aneurysm I: Introduction01:30

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...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
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...

Summary

Traumatic pericallosal artery aneurysms in children can be missed due to nonspecific symptoms. Early digital subtraction angiography (DSA) is crucial for diagnosis and prompt intervention to improve outcomes.

Area of Science:

  • Pediatric Neurosurgery
  • Vascular Neurology
  • Traumatic Brain Injury

Background:

  • Traumatic pericallosal artery aneurysms are rare but serious complications in children.
  • Delayed diagnosis can lead to severe neurological deficits or death.

Purpose of the Study:

  • To examine the clinical features, treatment strategies, and management considerations for pediatric traumatic pericallosal artery aneurysms.
  • To highlight the importance of timely diagnosis and intervention.

Main Methods:

  • Retrospective case analysis of a pediatric traumatic brain injury patient.
  • Comprehensive literature review on traumatic pericallosal artery aneurysms.

Main Results:

  • A case of delayed traumatic pericallosal artery aneurysm after head injury and surgery is presented.
  • Initial imaging was negative, but subsequent DSA confirmed the aneurysm, leading to embolization with an unfavorable outcome.

Conclusions:

  • Clinical and radiological signs of these aneurysms are often nonspecific, increasing the risk of missed diagnosis.
  • Early and potentially repeat DSA is vital for diagnosis.
  • Prompt surgical or endovascular treatment is recommended upon diagnosis.
