Insights

Coronary stent-grafts effectively treated a spontaneous internal carotid artery (ICA) dissection with a large pseudoaneurysm. This endovascular approach demonstrated successful closure without residual pseudoaneurysm at 9 months.

Area of Science:

  • Vascular Surgery
  • Interventional Neurology
  • Endovascular Therapy

Background:

  • Spontaneous internal carotid artery (ICA) dissection can lead to pseudoaneurysm formation, posing a risk of embolic events.
  • Endovascular treatment is an alternative to open surgery for managing complex carotid artery pathologies.

Observation:

  • A 68-year-old male presented with symptoms suggestive of carotid dissection and was found to have a large extracranial ICA pseudoaneurysm.
  • Contrast-enhanced CT confirmed a 3.5x3 cm left ICA pseudoaneurysm.

Findings:

  • Two coronary stent-grafts were successfully deployed endovascularly via percutaneous femoral artery access, completely excluding the pseudoaneurysm.
  • The patient remained hemodynamically stable during the procedure.
  • Follow-up duplex examination at 9 months showed no evidence of residual pseudoaneurysm, dissection, or endoleak.

Implications:

  • Covered coronary stents represent a viable endovascular option for treating spontaneous ICA dissection complicated by pseudoaneurysm.
  • This technique may offer a less invasive alternative for select patients with this rare condition.

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. This...

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...
