Dissecting pseudoaneurysm of the hepatic artery: a delayed complication of angioplasty in a liver transplant.
We report a 59-year-old female with a dissecting pseudoaneurysm of the allograft hepatic artery, as a delayed complication of percutaneous transluminal angioplasty (PTA). PTA of a severe anastomotic stenosis was successful, but complicated by a dissection involving the allograft hepatic artery. A large dissecting pseudoaneurysm developed and was incidentally detected during routine sonographic evaluation 14 months after PTA. Because of the extent of the pseudoaneurysm, percutaneous repair or surgical reconstruction was considered impossible. The patient underwent successful retransplantation 1 week after diagnosis.
