Thoracic Aneurysm

While relatively rare, thoracic aneurysms are increasing in frequency. Size of the aorta is considered the major factor in determining risk for dissection or rupture of a thoracic aneurysm.

Waiting period

Minimum — 3 months post-surgical repair

NOTE: If more than one waiting period applies (because of multiple cardiac conditions or other comorbid diseases), examine the driver for certification after the completion of the longest waiting period.

Decision

Maximum certification period — 1 year

Recommend to certify if:

The driver:

• Has a thoracic aneurysm less than 3.5 cm.
• Has a surgically repaired thoracic aneurysm and the driver meets post-surgical repair of aneurysm guidelines, including:
  • Has completed surgical repair waiting period.
  • Has medical clearance from a cardiovascular specialist who understands the functions and demands of commercial driving.

Recommend not to certify if:

The driver has a thoracic aneurysm greater than 3.5 cm.

Monitoring/Testing

You may on a case-by-case basis obtain additional tests and/or consultation to adequately assess driver medical fitness for duty.

Follow-up

The driver should have an annual medical examination.
