Transcatheter embolization for visceral pseudoaneurysm with situs inversus totalis

We present a case of visceral pseudoaneurysm with situs inversus totalis, which was treated by transcatheter embolization. A 58-year-old man with chronic pancreatitis and situs inversus totalis was admitted to our hospital for epigastric pain. On celiac arteriography, a pseudoaneurysm was detected at the anterior superior pancreaticoduodenal artery (ASPD). We catheterized the ASPD with a microcatheter introduced coaxially through a 5Fr catheter, and we isolated the pseudoaneurysm with microcoils. The patient's recovery was uneventful and he was discharged 17 days after the procedure. We describe this case because of the rarity of this anomaly, and it is important in that recognition may help avoid mishaps at interventions, particularly in the emergency setting.
