title: Hepatic perfusion abnormalities during treatment with hepatic arterial infusion chemotherapy: value of CT arteriography using an implantable port system.
abstract: OBJECTIVE
  The purpose of this study was to evaluate CT arteriography (CTA) using an implantable port system in the detection of perfusion abnormalities occurring during hepatic arterial infusion chemotherapy (HAIC).
  
  
  METHODS
  In 51 patients with unresectable primary and metastatic liver tumors, who had implanted port systems for HAIC, CTA examinations through the infusion pump were performed. When perfusion abnormalities were found, selective angiography and/or digital subtraction angiography using the implantable port system were performed to determine the etiology.
  
  
  RESULTS
  Forty-nine perfusion abnormalities were detected in 32 patients. Intrahepatic hypoperfusion was found in 24 cases. Of 11 patients in whom correction of the hypoperfusion was attempted, it was successful in 10. Of 13 patients in whom correction was not attempted, 6 patients showed progressive disease in nonperfused areas. Intrahepatic hyperperfusion was found in 14 cases, which showed no subsequent complication. Extrahepatic perfusion was found in 11 cases.
  
  
  CONCLUSIONS
  We consider CTA to be useful in detecting perfusion abnormalities that may compromise HAIC.
