Abstract
HAI catheter placement was attempted with modified CHAcoil 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 investigatedAll 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 sidehole 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
