Shema of mechanism of abdominal-organ malperfusion.
(a) True lumen stenosis type: True lumen is compressed by false lumen in aorta.
(b) Visceral artery dissection type: True lumen is compressed by false lumen in visceral artery.
(c) Mixed type: True lumen is compressed by false lumen in both aorta and visceral artery.
T: true lumen, F: false lumen, Arrows: direction of pressure |

Patient characteristics in acute type IIIb aortic dissection associated with abdominal-organ malperfusion |
|

|
Fig. 3 |
In Case 8, computed tomography on onset of acute abdomen.
True lumen compressed by false lumen in aorta was severely narrow, and false lumen was not patent. |

In Case 7, computed tomography on onset of acute type IIIb aortic dissection (a) and digital subtraction angiography on onset of acute abdomen (b).
(a) False lumen invaded into the orifice of celiac artery.
(b) The orifice of celiac artery was 99% stenosis. |

In Case 4, computed tomography (a) and digital subtraction angiography (b) on onset of acute type IIIb aortic dissection.
(a) True lumen compressed by false lumen in aorta was severely narrow, and false lumen invaded into the orifice of superior mesenteric artery (SMA).
(b) True lumen was severely narrow on thoraco-abdominal aorta level, and occluded on just below SMA level. Furthermore, the orifices of celiac artery and SMA were 99% stenosis. |
