[A case of difficult treatment of infected pseudoaneurysm of the femoral artery during hepatic arterial infusion chemotherapy for hepatocellular carcinoma].

For advanced hepatocellular carcinoma, an 80's woman underwent right inguinal reservoir port implantation and hepatic arterial infusion chemotherapy. The patient developed sepsis caused by methicillin-resistant Staphylococcus aureus 40 days after starting treatment. After the reservoir port was removed, an infected pseudoaneurysm developed. Interventional radiology treatment could not be completed because of the shape of the aneurysm, and deep femoral artery suture closure was conducted surgically. Unfortunately, the pseudoaneurysm recurred two months after surgery, and treatment for hepatocellular carcinoma was discontinued. It is important to remember that the formation of pseudoaneurysms is a complication after reservoir port placement.
