Totally implantable arterial device (TIAD): a questionable complication.

The authors report a complication of a totally implantable arterial device in a patient in which the device was inserted to prevent recurrence of hepatic metastasis. After intrahepatic chemotherapy, during the nursing of the totally implantable arterial device, the patient developed a mass close to the duodenal loop that disappeared seven months later. The spontaneous decrease of this mass suggests the hypothesis of a hematoma due to a rupture of a pseudoaneurysm of a small collateral artery.
