Use of autogenous internal iliac artery for bridging the external iliac artery after excision of Aspergillus mycotic aneurysm in renal transplant recipients

Repair of vascular defects in the presence of infection remains a challenging task in immunocompromised patients. We report two patients with postrenal transplant Aspergillus mycotic aneurysms of the allograft renal artery involving the external iliac artery which were excised along with the allograft. The defect in the external iliac artery was repaired successfully with interposition of autogenous internal iliac artery graft. Use of an internal iliac artery graft in such settings has been rarely reported in English literature. Autogenous internal iliac artery grafts provide a useful method to bridge the vascular defects created by radical debridement in the presence of fungal infections. (J Vase Surg 2011;53:802-4.)
