[Endovascular treatment of aneurysms after implantation of an aortic-femoral homograft bypass].
METHODS
We report on two rare endovascular procedures concerning aneurysmatic complications of arterial homografts. In both cases infected aortobifemoral grafts were explanted und replaced by cryopreserved aortofemoral homografts on the left side. The revascularisations on the right side were performed with the deep femoral vein in one case, and by desobliteration of the iliac artery in the other case. After 4 and 10 months, respectively, we found aneurysmatic enlargements of the aortic anastomoses. In both cases we excluded a false aortic aneurysm by uniiliac stentgrafts in combination with a femoro-femoral cross-over bypass for the contralateral leg. Both operations were carried out successfully. However, one patient developed an infection of the stent graft. We explanted the stent graft und performed an aortobifemoral bypass procedure with arterial cryopreserved homograft once again.


CONCLUSIONS
Both aneurysmatic complications after aortofemoral homograft implantation could be treated successfully by an endovascular approach. Possible late complications caused by the implantation of homografts or by endovascular procedures can be only detected in due time by a follow-up at short intervals.
