Extensive aortic dissection extending from the mid ascending aorta to the upper abdominal aorta, just above the origin of the superior mesenteric artery - this is unchanged compared to the previous study. New findings of marked dilatation of the distal aortic arch and descending thoracic aorta. The descending portion now measures 6.6 cm in transverse diameter and the mid aortic arch measures 7.2 cm. Extensive mural haematoma in the arch and descending portion, and there is evidence of acute intramural haemorrhage, arising from the superolateral aspect of the aortic arch.
No gross mediastinal haemorrhage, pleural or pericardial effusion.
No significant findings within the solid upper abdominal organs. Normal bilateral renal enhancement. New significant increase in size of the upper abdominal aorta which measures 4.7 cm in AP calibre compared to around 2.6 cm previously. No significant intramural haematoma within the abdominal aorta.
No free abdominal or pelvic fluid.
