Abstract
Purpose: To report the novel management of a persistent type 1 endoleak with Onyx embolisation. Case Report: A 75-year-old male presented with a type 1a endoleak 4 years after endovascular aortic aneurysm repair (EVAR). The patient was unfit for open surgery and received an aortic cuff with chimneys for renal arteries. Six months later, enlargement of aneurysm sac was detected. Aortography confirmed the diagnosis and the endoleakentry site was selectively catheterised and embolised with Onyx. Follow-up imaging with computed tomography (CT) and contrast-enhanced ultrasound at 12 months showed no residual endoleak and stable sac size. Conclusions: Type 1 endoleak after EVAR can be treated successfully with Onyx embolisation when standard endovascular techniques have failed and surgical options are unsuitable due to severe comorbidity.
