Endovascular treatment of chronic type b dissection at dong nai general hospital: A case report

Abstract

Introduction: Chronic type B aortic dissection is a disease that can lead to false lumaen dilatation, which carries a risk of aortic rupture and sudden death. Endovascular intervention to treat this disease has been carried out at major centers in Vietnam. We report 1 case of endovascular intervention for chronic type B aortic dissection at Dong Nai General Hospital.[1]
 Case report: A 76-year-old male patient was admitted to the hospital because of incidentally finding of mediastinum dilatation on chest x ray. The patient had a history of severe retrosternal chest pain radiating to the back 3 months before admission. Computed tomography showed chronic type B dissection, primary entry point diameter of 16.3 mm, maximum aortic diameter of 46.6 x 47.7 mm. The patient underwent endovascular intervention, a 40 x 36 x 150 mm Medtronic Valiant Captivia graft was used, half of the left subclavian artery was covered. The results were good, the false lumen was partially thrombosed. The patient was discharged from the hospital in a stable condition 4 days after the intervention.
 Conclusion: Endovascular intervention for chronic aortic dissection at Dong Nai General Hospital can be applied safely. The implementation of this technique would benefit local patients and promote the development of the hospital.
