Insights

A patient with low back pain and intermittent claudication had an abdominal aortic aneurysm (AAA) and aorto-iliac disease. Surgical repair with an aorto-bifemoral bypass graft successfully treated the chronic contained rupture (CCR).

Area of Science:

  • Vascular Surgery
  • Infectious Disease
  • Radiology

Background:

  • A 63-year-old male presented with chronic low back pain and bilateral intermittent claudication.
  • Imaging revealed a 4 cm abdominal aortic aneurysm (AAA), severe aorto-iliac disease, psoas collection, and vertebral erosion suggestive of spondylodiscitis.

Observation:

  • Lumbar spine MRI suggested spondylodiscitis at L4-L5.
  • Initial antibiotic treatment for suspected infection was unsuccessful.

Findings:

  • A chronic contained rupture (CCR) of the posterior aortic wall was identified during surgery.
  • The patient underwent successful repair with an aorto-bifemoral bypass graft.

Implications:

  • This case highlights the importance of considering AAA in patients with back pain and claudication.
  • Surgical intervention is crucial for managing complex AAA with associated spinal pathology and infection.
  • Successful aorto-bifemoral bypass grafting can effectively treat AAA and aorto-iliac occlusive disease.

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 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.

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
