Insights

Endovascular repair for chronic type B aortic dissection showed long-term success but late intimal injury. Reintervention was needed for stent graft complications in both patients.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Endovascular Therapy

Background:

  • Chronic type B aortic dissection requires effective treatment strategies.
  • Endovascular repair offers a minimally invasive option for aortic dissection.

Observation:

  • Two patients with chronic type B aortic dissection underwent successful endovascular repair with stent grafting.
  • Follow-up revealed late intimal injury at the stent graft's distal end in both patients, occurring at 2 and 6 years post-procedure.

Findings:

  • Successful initial endovascular repair of chronic type B aortic dissection.
  • Development of late intimal injury at the stent graft-induced entry site is a potential complication.
  • Reintervention, including graft replacement or additional stent grafting, was necessary to manage complications.

Implications:

  • Long-term surveillance is crucial after endovascular repair for aortic dissection.
  • Intimal injury represents a significant late complication requiring further management.
  • Endovascular techniques for aortic dissection necessitate ongoing refinement to mitigate long-term risks.

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...
