Aneurysm I: Introduction

620
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

458
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

542
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...

Aneurysm IV: Nursing Management

598
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...

Summary

Intracranial aneurysm hemodynamics can change due to geometric alterations near rupture. This finding suggests caution when interpreting studies comparing ruptured and unruptured aneurysms based solely on hemodynamics.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computational Fluid Dynamics

Background:

  • Intracranial aneurysm rupture risk is linked to hemodynamics.
  • Previous studies compared hemodynamics of ruptured vs. unruptured aneurysms.
  • Aneurysm geometry may change around rupture, altering hemodynamics.

Purpose of the Study:

  • To assess changes in intracranial aneurysm hemodynamics.
  • To investigate hemodynamic alterations due to geometric changes before, during, or after rupture.

Main Methods:

  • 3D imaging (MRA, CTA, 3D rotational angiography) used before and after rupture.
  • Geometric models of aneurysms and vasculature generated.
  • Computational fluid dynamics (CFD) simulated intra-aneurysmal hemodynamics.
  • Flow complexity, stability, inflow concentration, and impingement qualitatively assessed.

Main Results:

  • Hemodynamics changed in 6 out of 9 aneurysms.
  • Observed changes included flow complexity, stability, inflow concentration, and impingement.
  • Changes were associated with aneurysm displacement, growth, or new lobulations due to rupture.

Conclusions:

  • Geometric changes can alter intracranial aneurysm hemodynamics.
  • Findings suggest caution when interpreting hemodynamic associations with rupture from case-control studies.
