Vascular complications are reported in a significant proportion of patients following renal transplantation and are a contributory cause of graft dysfunction.

We present three patients in whom extra-renal transplant artery pseduoaneurysms arising from the surgical anastomosis between the external iliac and renal transplant artery were initially diagnosed with colour Doppler ultrasound, and outline their subsequent management.
