Emergency endovascular repair of acute descending thoracic aortic dissection

Abstract

Background

Acute descending thoracic aortic dissection is a life-threatening emergency. It is not often considered as the initial diagnosis in patients presenting with epigastric pain and could easily be missed in a busy casualty department.

Aim

This case report is aimed to highlight the feasibility of the technique and the need for long-term surveillance following endovascular repair of acute thoracic aortic dissection.

Results

The patient presented with epigastric pain radiating to the interscapular region with a stable hemodynamic status. A computerized tomography (CT) scan demonstrated type B thoracic aortic dissection of the proximal descending thoracic aorta. A successful endovascular repair was carried out with uneventful recovery and follow-up CT scan six years after stent-grafting shows satisfactory position of the stent-graft, patent false lumen in the abdominal aorta perfusing the right kidney, and progressively enlarging diameter of the abdominal aorta.

Conclusion

Thoracic aortic dissection should be considered as a differential diagnosis in patients presenting with epigastric and interscapular chest pain. Emergency endovascular repair of acute thoracic aortic dissection is feasible and relatively safe. Regular follow-up with CT scan is required to evaluate the long-term efficacy and identify the need for re-intervention.
