He noted that imaging is the gold standard for diagnosing aneurysms, and there are medical guidelines that recommend testing based on assessment of certain risk factors.
“If someone with a positive thumb test also has features suggestive of Marfan syndrome, Ehlers-Danlos, or a family history of aneurysm or dissection, they should discuss it with a physician who may recommend formal evaluation and imaging of the aorta,” Rambhatla said. “If it’s an isolated finding in an otherwise healthy person, it usually does not warrant urgent concern but can be brought up at a routine medical visit for context.”
Hirsch also recommended that people discuss risk factors with their physicians to determine when screening and monitoring is appropriate.
