Figure 8d. Chronic Stanford type B dissection. (a) DSA image shows an entry tear (arrow) in the distal descending aorta and injected contrast material in the false lumen. The dissection extends distally into the abdominal aorta. The abdominal branch vessels are supplied by the compressed true lumen. C = celiac trunk, LRA = left renal artery, RRA = right renal artery, SMA = superior mesenteric artery. (b) DSA image obtained after stent-graft placement shows complete exclusion of the false lumen. The flow to all visceral vessels from the true lumen is maintained. (c) Pretreatment CT scan shows compression of the true lumen by the dilated false lumen (*) at the level of the entry site. (d) Pretreatment CT scan shows that the celiac trunk is supplied by the true lumen. Note the partial thrombosis of the false lumen (*). (e) CT scan obtained at 3-month follow-up shows that exclusion of the entry site has led to thrombosis of the thoracic component of the false lumen (*). (f) CT scan obtained at 3-month follow-up shows that the caliber of the abdominal aorta has been reestablished. The false lumen is completely thrombosed (*).
