Abstract

Insights

Pseudoaneurysms and fistulas are rare complications following cardiac pacemaker implantation. Angioembolization offers an effective and safe treatment option for these uncommon issues.

Area of Science:

  • Cardiology
  • Interventional Radiology
  • Medical Device Complications

Background:

  • Cardiac implantable electronic devices (CIEDs) can lead to various complications, including infection, pneumothorax, hematoma, lead displacement, and perforation.
  • Pseudoaneurysms and fistulas are rare but serious complications associated with CIEDs, often lacking extensive documentation.

Observation:

  • A case report details a patient with severe sepsis who developed a pseudoaneurysm and fistula two weeks post-insertion of an externalized cardiac pacemaker.
  • The patient's condition required intervention by Interventional Radiology.

Findings:

  • Diagnosis of these rare complications relies on clinical assessment and multimodal imaging techniques.
  • Successful angioembolization was performed by Interventional Radiology for the patient's pseudoaneurysm and fistula.

Implications:

  • Recognizing pseudoaneurysm as a potential delayed complication of pacemaker implantation is crucial.
  • Angioembolization presents a safe and effective therapeutic strategy for managing pacemaker-induced pseudoaneurysms and fistulas.
  • Treatment decisions should integrate institutional protocols, imaging results, and multidisciplinary heart team recommendations.

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...

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 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...
