Endovascular contrast enhanced vessel delineation using X-ray fluoroscopy instead of DSA with flush of contrast medium into the aneurysm (A). After selective probing of the left uterine artery with a microcatheter better visualization of the true UAA and demarcation of another uterine branch (arrow) that should be preserved during embolization (B). Back-door of the true UAA and a little flush of contrast medium (arrow) after overinjection (C). Back-door (D), intra-aneurysm (E) and front-door (F) coil-embolization preserving the initial shown other uterine branch (F, arrow). In the final X-ray fluoroscopy, there is no contrast enhancement of the uterine vessel leading to the UAA (F). Altogether 34 coils (Cook: 2 mm Hilal, 3 mm / 8 mm / 10 mm Nester; BostonScientific: 3 mm IDC, 20 mm Interlock) were used for embolization
