title: Withdrawal of port-catheter system for hepatic arterial infusion chemotherapy implanted with fixed catheter tip method.
abstract: OBJECTIVE
  To evaluate the feasibility and safety of a method to withdraw port-catheter systems implanted by the fixed catheter tip method.
  
  
  METHODS
  Retrospective review was conducted of 14 cases of unresectable advanced liver cancer in which it was necessary to attempt 15 withdrawals of percutaneously placed implantable port-catheter systems. Reasons for withdrawal, withdrawal success, complications, and subsequent treatment of patient were evaluated.
  
  
  RESULTS
  In 14 of the 15 procedures (93.3%), the port-catheter system was successfully retrieved. Because continuation of hepatic arterial infusion chemotherapy was necessary in 10 procedures, a second implantation was performed after withdrawal of the initial catheter. Only one complication occurred, in which the indwelling catheter was broken in the aorta during withdrawal.
  
  
  CONCLUSIONS
  When retrieval of a port-catheter system implanted with the fixed catheter tip method is necessary, withdrawal can be accomplished safely with high frequency.
