Insights

Extracranial internal carotid artery (ICA) mycotic aneurysms are rare and dangerous. A Proteus mirabilis infection in an extracranial ICA aneurysm was successfully treated using a saphenous vein graft.

Area of Science:

  • Vascular Surgery
  • Infectious Diseases
  • Neurology

Background:

  • Extracranial internal carotid artery (ICA) mycotic aneurysms are uncommon vascular lesions.
  • These aneurysms pose a high risk of severe neurological complications and death.
  • Management of these aneurysms presents significant surgical challenges.

Observation:

  • A case of a contained ruptured mycotic aneurysm in the extracranial ICA was reported.
  • The aneurysm was associated with an infection caused by Proteus mirabilis.
  • The patient's condition required urgent and effective treatment.

Findings:

  • The mycotic aneurysm was successfully treated using an end-to-end spatulated interposition saphenous vein graft.
  • This surgical technique provided a durable repair and resolved the infection.
  • The patient experienced a favorable outcome without significant neurological sequelae.

Implications:

  • This case highlights the efficacy of saphenous vein grafting for managing infected extracranial ICA aneurysms.
  • The findings suggest that this technique can be a valuable option in complex vascular reconstructions.
  • Successful treatment can prevent devastating neurological events in patients with mycotic aneurysms.

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...

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...

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 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...

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...
