A quiet aortic aneurysm

"A Chandigarh gentleman, an incidental CT finding, and the year we chose not to intervene."

Presenting

68-year-old man, ex-smoker, referred after a CT for unrelated back pain incidentally noted a 4.6-cm infra-renal aortic aneurysm. He was asymptomatic. Two colleagues had already recommended he 'get it stented before something happens.'

The read

The aneurysm was 4.6 cm — below the standard 5.5 cm intervention threshold for men. Growth rate is what matters at this size. There was no prior scan to compare, so we did not know if he was slow-growing or fast-growing. Intervening now would be treating a number, not a patient.

03
The plan we chose

Ultrasound surveillance at 6 months and 12 months. Blood pressure and cholesterol optimised in coordination with his GP. Smoking already stopped (relevant). A stent-graft was and remains an option — but not until the aneurysm earns it.

04
One year later

Growth 2 mm over 12 months (well within slow-growth range). Continued 12-monthly surveillance. He has not had a procedure. If growth accelerates, or the aneurysm passes 5.5 cm, EVAR remains straightforward. Meanwhile he continues an ordinary life, which is the point.

— The lesson
"Not every finding needs a procedure. A stent is not the same as an answer. Sometimes the best treatment is the one you don't do — and the discipline to review it in six months."
