Iatrogenic migration of iliac stent graft that was implanted for the reason of iliac artery perforation at the beginning of TAVI into the ascending aorta during the procedure
Angiography of iliac and femoral arteries. Picture (A) shows perforation of right external iliac artery by 10 Fr sheath. Red arrow marks area of perforation, blue shows huge retroperitoneal bleeding, and black indicates guiding wire outside of artery, i.e., in retroperitoneal space. (B) Fluoroscopy of pelvis shows implanted stent graft BeGraft 8x57 mm in right external iliac artery (black arrow). (C) The angiography of right iliac and femoral artery after implantation of stent graft shows no leakage of iodine contrast out of artery into retroperitoneal space.
Figure 2
(A) Fluoroscopy of the chest showing stent graft BeGraft 8x57 dislocated from external iliac artery into ascending aorta (black arrow) due to unintentional entrapment by Lunderquist guiding wire and Vertebral catheter. (B) Fluoroscopy showing stent graft BeGraft 8x57 mm (red arrow) caught by loop snare device Multi-Snare® (blue arrow).
Figure 3
(A) Angiography of right iliac arteries shows balloon inflated in external iliac artery after dislocation of stent graft BeGraft 8x57 mm (red arrow) in order to stop bleeding. Blue arrow indicates small leakage of iodine contrast from external iliac artery despite inflated balloon, i.e., it marks area of perforation. (B) Fluoroscopy of pelvis shows new stent graft implanted into right external iliac artery (black arrow). (C) Angiography of right iliac artery shows no acute leakage of iodine contrast after stent graft implantation. However, a small amount of iodine contrast is visible near the stent graft that got out from the artery prior to the second stent graft implantation.
