Insights

A patient with a history of SARS-CoV-2 infection developed a stent graft complication. A secondary thoracic endovascular aortic repair (T-EVAR) successfully treated the dissection, showing good aortic remodeling at one year.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Medical Imaging

Background:

  • A 45-year-old male patient with a history of SARS-CoV-2 infection underwent thoracic endovascular aortic repair (T-EVAR) for a type B intramural hematoma.
  • Post-T-EVAR complications included a neointimal tear and dissection within the Hercules stent graft.

Purpose of the Study:

  • To describe the management and outcome of a patient with a stent graft complication after T-EVAR.
  • To evaluate the efficacy of a secondary relining T-EVAR procedure.

Main Methods:

  • Computed tomography angiography (CTA) was used for diagnosis and follow-up.
  • A secondary relining T-EVAR procedure was performed using a Hercules stent graft.
  • One-year follow-up included clinical assessment and control CTA.

Main Results:

  • The secondary T-EVAR successfully addressed the neointimal tear and dissection.
  • No complications or disease recurrence were observed at the one-year follow-up.
  • Control CTA demonstrated favorable aortic remodeling.

Conclusions:

  • Secondary relining T-EVAR is a viable option for managing stent graft complications.
  • This approach can lead to successful disease management and positive aortic remodeling.
  • Further studies are warranted to confirm long-term outcomes.
