title: Side-Hole Catheter Placement with Fixation and Embolization in Common Hepatic Artery for Hepatic Arterial Infusion Chemotherapy (Modified CHA-Coil Method) for Patients with Celiac Artery Stenosis or Occlusion.
abstract: OBJECTIVE
  We retrospectively assessed the feasibility of a side-hole catheter placement with fixation and embolization in the common hepatic artery (CHA) (modified CHA-coil method) for hepatic arterial infusion (HAI) chemotherapy.
  
  
  METHODS
  HAI catheter placement was attempted with modified CHA-coil method in five patients with unresectable hepatic malignancies between 2000 and 2013. The reason for using this method, the mode of catheter placement, and the duration of HAI were investigated.
  
  
  RESULTS
  All patients had either occlusion or stenosis of the celiac artery (CA) or CHA, and, as a result, CHA blood flow had either reversed or decreased and hepatopetal GDA flow was observed. In three patients, the proper hepatic artery was extremely short. The side-hole catheter was inserted through the left subclavian artery and was placed from CA to the right gastroepiploic artery in an anterograde manner (n = 4) and from the superior mesenteric artery to the splenic artery in a retrograde manner through GDA (n = 1). The side hole of the catheter was positioned at the proximal portion of GDA. Using a separate catheter inserted from the right femoral artery, coils were placed around the indwelling catheter of CHA to embolize CHA and to fix the catheter. Coil mislocation was not observed, and catheter placement was successful in all patients. HAI chemotherapy was administered for a median of 136 days. The catheter displacement was not observed during HAI.
  
  
  CONCLUSIONS
  The modified CHA-coil method can be used as a stable method for catheter placement when CHA is narrow or there is retrograde CHA blood flow.
