Summary:

Description
  • Radiopaedia case ID: 85272
  • Study ID: 100847
  • Image ID: 54098499
  • Plane projection: Axial
  • Modality: CT
  • System: Vascular
  • Findings: Chest radiograph without evidence of an acute cardiopulmonary process. Lungs fields clear bilaterally. Unremarkable cardiomediastinal silhouette. Thoracic spine radiographs demonstrate moderate diminution of intervertebral disc space height most prominently in the lower thoracic spine, accompanied by end plate spurring, consistent with mild-moderate degenerative changes.
  • Study findings: Demonstrates a Stanford B aortic dissection, with an intraluminal flap arising just distal to the left subclavian origin, extending through the descending and abdominal aorta to at least the bilateral common iliac arteries and likely the proximal external iliac arteries. Diameter of the ascending aorta is normal. No pericardial effusion. The false lumen has a transverse diameter of 1.7 cm and has a segment of thrombus in the proximal 2 cm, but is otherwise patent. The true lumen is located medially, and measures 8 mm in transverse diameter. The intimal flap appears to involve the orifice of the superior mesenteric artery, with a segment of intraluminal thrombus involving a short length of the proximal SMA, flow reconstitution appears to occur distally. The origins of the left innominate artery, left common carotid artery, left subclavian artery, celiac trunk, common hepatic artery, splenic artery, and inferior mesenteric arteries are patent. No intraperitoneal or pelvic free fluid, lymphadenopathy, or masses.
