These concerns need timely advice but are not always emergencies.
Call emergency services for sudden severe pain, fainting, severe breathlessness, stroke-like symptoms, or a suddenly cold, painful, weak limb.
Contact the treating team promptly for new or increasing chest, back, or abdominal discomfort, reduced exercise tolerance, medication problems, or consistently higher blood pressure readings.
These symptoms should not wait for a routine appointment.
Aortic dissection requires lifelong follow-up with a cardiovascular clinician.
Care may involve a cardiologist, vascular surgeon, cardiac surgeon, genetics specialist, or a dedicated aortic disease center.
Routine follow-up should review blood pressure, medicines, activity, symptoms, and imaging results.
Patients can ask whether they should measure blood pressure at home and what range their care team recommends.

CT or MRI scans are used to monitor the repaired and unrepaired parts of the aorta.
For people with residual aortic disease after an acute dissection, major US guidance recommends imaging after 1 month, 6 months, and 12 months, then annually if findings remain stable.
The schedule may differ based on the repair, imaging results, kidney function, and individual risk.
Genetic counseling or testing may be appropriate when dissection occurs at a younger age, runs in the family, or appears with features of an inherited condition.
First-degree relatives—parents, siblings, and children—may be advised to have aortic imaging even if genetic testing does not identify a cause.
