demonstrates the second step of the maneuver – introduction and placement of the greater and potentially more traumatic large bore microcatheter and the succeeding FDS implantation. a Plain radiography in working projection shows the placement of the delivery-microcatheter in the distal A2 segment, providing sufficient forerun for the delivery of the densely woven FDS. b DSA confirmation of the true lumen by injection of contrast agent via the correctly positioned microcatheter prior implantation. c Plain radiography in working projection demonstrating FDS delivery – note the radiopaque olive at the distal end of the p48 wire and the tulip-like appearance of the partially unfolded distal device. d Plain radiography of the implanted FDS, optimally covering the aneurysm neck originating from the A1-A2 curve
