Figure 13a. Transcatheter embolization of pseudoaneurysms and an AVF in a 33-year-old man with renal transplant dysfunction. (a) Angiogram of the transplant renal artery shows pseudoaneurysms and an AVF supplied by an enlarged lower segmental artery. (b) Selective angiogram of the segmental artery obtained after proximal embolization of the artery with coils shows successful exclusion of the pseudoaneurysms and AVF. Note the preservation of flow in the upper and middle segmental branches.
