7.8.1. Long-Term Surveillance Imaging After Aortic Dissection
and IMH
COR LOE
Recommendations
1 B-NR 1. In patients who have had an acute aortic dissection and IMH
treated with either open or endovascular aortic repair and
have residual aortic disease, surveillance imaging with a CT
(or MRI) is recommended after 1 month, 6 months, and 12
months and then, if stable, annually thereafter.
1 B-NR 2. In patients who have had an acute aortic dissection and IMH
that was managed with medical therapy alone, surveillance
imaging with a CT (or MRI) is recommended after 1 month, 6
months, and 12 months and then, if stable, annually thereafter.
7.8.2. Long-Term Management After Acute Aortic Dissection
and IMH
COR LOE
Recommendation
1 B-NR 1. In patients with a previous acute aortic dissection and IMH,
whether initially treated medically or with intervention, who
have chronic residual TAD and an aneurysm with a total
aortic diameter of ≥5.5 cm, elective thoracic aortic repair is
recommended.
7.8.3. Long-Term Management and Surveillance for PAUs
COR LOE
Recommendations
2a C-LD 1. In patients with a PAU who have undergone aortic repair,
surveillance imaging at intervals appropriate for the repair
approach and location (see Section 6.5.6, "Surveillance After
Aneurysm Repair") is reasonable.
2a C-LD 2. In patients with a PAU that is being managed medically,
surveillance imaging with a CT is reasonable at 1 month after
the diagnosis and, if stable, every 6 months for 2 years, and
then at appropriate intervals thereafter (depending on patient
age and PAU characteristics).
