Left:
dissection membrane starts approx. 2 cm above the aortic valve, the ascendant aorta is aneurysmatic.
Right:
view of the ascendant aorta, so far it can be seen in the TEE examination. The left main bronchus
hinders usually visuali- zation of intersection of ascendant aorta to the aortic arch.
Left:
cross-section of the ascen- dant aorta in the same case. Notice the intramural hematoma previous to start
of dissection membrane.
Right:
further away of the aortic valve, intramural hematoma and start of dissection membrane.
Standford B
Left:
descendant aorta short after intersection from the aortic arch. Flat, wall-adherent plaques.
Right:
same case, further distal from in the descendant aorta, a large intramural hematoma can be seen.
Left:
more distal, a dissection membrane with entrance tear can be seen. False lumen at the bottom of the image.
Right:
dissection membrane with entrance tear and color Doppler flow display.
Left:
dissection membrane with entrance tear and PW-Doppler flow display.
Right:
further distal in the descen- dant aorta, pronounced spontane- ous echo contrast in false lumen.
