    Abstract:
    Complicated acute nonA-nonB dissection with malperfusion is associated with a high in-hospital mortality up to 67%. Therefore, rapid identification and treatment are critical for clinical outcomes. We report the urgent treatment of a complicated subacute aortic dissection treated with a physician-modified-endograft (PMEG) fenestrated-TEVAR (f-TEVAR) for the left common carotid artery (LCCA). A 49-year-old male patient with acute non-A non-B aortic dissection with complete true lumen collapse and associated mesenteric and renal ischemia, was referred to another vascular center for abdominal pain and received exclusively medical treatment. After 15 days of persistent pain, the patient self-referred to our center and was treated with endovascular repair. The proximal entry tear was located at the level of the left subclavian artery: a PMEG f-TEVAR was performed with fenestration for LCCA in conjunction with carotid-subclavian bypass. In addition, spot stenting of the left renal artery was performed to resolve renal malperfusion. The final angiography showed satisfactory result. The patient soon reported significant pain relief. Follow-up at 30-days was satisfactory, with no need for further intervention. A physician-modified fenestrated-TEVAR can be used in emergency setting to treat acute non-A-non-B aortic dissection in conjunction with multiorgan malperfusion, with satisfactory results even after initial delayed treatment.
