Findings and procedure details
- CT scans have been collected on patients with MS and Acute Aortic Syndrome who underwent aortic repair during the past 7 years in the Department of Cardiac Surgery.
- The appropriate surgical approach was based on the localization of tear, extend of the flap, patency of true and false lumens, perfusion.
- In all cases, an initial intimal tear was available in ascending aorta. The majority of patients had second or third surgeries for a reason of dissections at other sites or aneurysms.
Proximal part of the aorta:
1. Size of the aortic annulus
2. Aneurysm of Valsalva sinuses
3. Severe transaortic valve regurgitation
(Fig. 8)
Distal part of the aorta:
1. Patency of the false and true lumens, their size
2. Aneurysm (dilatation) of the false lumen
3. Intraluminal thrombus with the embolic syndrome
4. Paraaortal haematoma
(Fig. 9); (Fig. 10).
Patients after 1st stage surgery of AAD should be examined with CT scan at least 1 time a year.
- Patients must be scheduled for surgery (open or endovascular) in case of verification that dimensions of the aorta are exceeded [in any vulnerable part] (Fig. 11)
- If true or false lumen is dilated
The question: “Can we radical treat aortic dissection?” opens still now
