Extensive iatrogenic aortic dissection during renal angioplasty: successful treatment with a covered stent-graft.
An extensive iatrogenic aortic type B dissection during percutaneous transluminal renal angioplasty (PTRA) for bilateral renal artery stenosis was treated with a covered stent placed in the right renal artery. Control angiography confirmed closure of the entry. Postprocedural CT demonstrated a thick intramural hematoma (IMH) up to the left subclavian artery. CT follow-up at 8 months showed an almost complete resorption of the IMH. While medical treatment is the standard therapy for type B dissections, closure of the intimal tear with a covered stent may be an additional option in extensive cases during PTRA.
