Insights

A ruptured anterior communicating artery (Acom) aneurysm caused a brain hemorrhage and seizures in a 15-month-old infant. Endovascular stent coiling successfully treated the aneurysm, leading to a full recovery without neurological deficits.

Area of Science:

  • Pediatric Neurology
  • Vascular Neurosurgery
  • Neuroradiology

Background:

  • Intracranial hemorrhage in infants can be caused by various factors, including vascular anomalies.
  • Ruptured cerebral aneurysms are rare in pediatric populations but can lead to severe neurological consequences.

Purpose of the Study:

  • To report a rare case of a ruptured anterior communicating artery aneurysm presenting with intraparenchymal hemorrhage and seizures in a 15-month-old infant.
  • To highlight the successful endovascular management of this condition.

Main Methods:

  • A 15-month-old infant with acute neurological symptoms underwent diagnostic imaging, including CT angiography (CTA) and diagnostic angiography.
  • Endovascular stent coiling was performed to treat the ruptured aneurysm.
  • Follow-up magnetic resonance angiography (MRA) was conducted.

Main Results:

  • Imaging revealed an intraparenchymal hemorrhage in the left frontobasal region extending into the ventricles, with evidence of a ruptured Acom aneurysm.
  • Endovascular stent coiling was performed without hematoma evacuation.
  • At 1-year follow-up, the patient showed symptom improvement without neurological sequelae, and MRA confirmed no residual aneurysm filling.

Conclusions:

  • Ruptured Acom aneurysms, though rare in infants, can present with devastating intracranial hemorrhage and seizures.
  • Endovascular stent coiling is a viable and effective treatment option for pediatric Acom aneurysms, leading to favorable outcomes.

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.

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

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...
