The reversed umbrella: displacement of a Contour device into an MCA aneurysm 18 months after treatment
Summary
The Contour is a promising new device designed to treat large-neck intra-cranial aneurysms. We describe a first case of Contour device displacement 18 months after initial treatment.
A patient with a 10 mm unruptured right middle cerebral artery bifurcation aneurysm was treated with a 9 mm Contour. The device was correctly positioned at the neck during treatment and at the 6 month angiography follow-up. At 18 months follow-up we noticed a full displacement of the device into the aneurysm dome. The Contour had a reversed shape and the aneurysm was still fully opacified. No neurological event occurred during the whole follow-up. Contour may be a promising tool but needs to be assessed over a long-term period.
