Aneurysm I: Introduction

18
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

17
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

18
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...

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Cystic artery pseudoaneurysm (CAP) is a rare condition with poorly understood etiology and presentation.
  • Surgical treatment, typically cholecystectomy and cystic artery ligation, is challenging and risky, especially with acute inflammation and bleeding.
  • Comorbidities may preclude surgical intervention in some patients.

Observation:

  • An 81-year-old male presented with epigastric pain and melena, indicative of gastrointestinal bleeding.
  • Imaging revealed a cystic artery pseudoaneurysm and gallbladder distention.
  • The patient had significant cardiopulmonary comorbidities, making general anesthesia high-risk.

Findings:

  • Endovascular embolization successfully occluded the cystic artery pseudoaneurysm.
  • Percutaneous drainage managed the distended gallbladder.
  • The patient's condition stabilized without surgical intervention.

Implications:

  • Endovascular embolization offers a viable alternative to surgery for managing cystic artery pseudoaneurysms.
  • Combined endovascular and percutaneous drainage can be a life-saving approach for high-risk patients.
  • This case highlights the importance of considering less invasive options for complex vascular pathologies.
