Late onset anastomotic pseudoaneurysm of renal allograft artery: case report, diagnosis, and treatment.

A large, late onset, extrarenal pseudoaneurysm at the anastomotic site of the renal allograft artery is reported herein. The patient was a 25-year-old woman who presented 2 months after a normal vaginal delivery. She had received a renal allograft 6 years before admission without any renal compliants after transplantation. She presented with lower abdominal pain and an elevated creatinine level. Digital subtraction angiography revealed a pseudoaneurysm at the anastomotic site; surgical treatment was performed via a venous patch angioplasty. She has been followed postoperatively for 18 months with normal kidney function and without any other renal or vascular problems.
