Abstract
INTRODUCTION
Brachial artery aneurysm (BAA) following long-standing arteriovenous fistula (AVF) ligation after renal transplantation is odd.
CASE PRESENTATION
Two cases of brachial artery aneurysm treated with bypass (a saphenous vein graft and a PTFE graft). In the first patient no complications were recorded whereas an infection was diagnosed after 6 months from the procedure in the second treatment.
CLINICAL DISCUSSION
Multiple factors activated by stress on the vessel wall followed by fistula ligation are the cause of vascular remodeling of the three layers making up the wall with possible evolution in aneurysmatic lesions. In literature the gold standard for this lesion is the surgical approach, only one endovascular procedure is reported. The traditional surgical approach uses the autologous vein or prosthetic PTFE grafts.
CONCLUSION
Brachial artery aneurysm is a complication that affects patients undergoing renal transplantation who have already undergone AVF ligation. In our experience autologous vein graft represented the best solution.
