 ( A ) Perioperative fluoroscopic view. Initial angiography through the pigtail catheter in the ascending aorta confirmed the Dacron dilatation and false aneurysm. ( B ) Control angiography demonstrates successful implantation and false-aneurysm exclusion. Figure 8 markers: white (*) pigtail catheter in the ascending aorta; black arrow, pigtail catheter inside the ascending aorta; proximal figure 8 markers distal from the proximal anastomosis once the stent graft is delivered.
