Embolization of a Jejunal Artery Pseudoaneurysm via Collateral Vessels

Figure 1

34-year-old woman presenting a jejunal artery pseudoaneurysm treated by transcatheter embolization via collaterals vessels. (a) Sagittal contrast enhanced CT image showing a pseudoaneurysm emerging from the first SMA branch (jejunal artery) just after its origin. (b) Digital angiogram obtained after coil embolization shows that pseudoaneurysm is still partially patent (white arrow) requiring further embolization; however subsequent direct catheterization was not possible. The image shows a collateral vascular arc between the first and the second jejunal arteries. (c) The collateral vascular arc was used to obtain pseudoaneurysm catheterization. (d) Complete embolization was finally obtained.
