Placement of 125I seed strands and stents for a type IV Klatskin tumor

Figure 1 A 75-year-old man with a Bismuth type IV Klatskin tumor was treated via the placement of ¹²⁵I seed strands and stents in the right and left intrahepatic bile ducts. A: An 8.5-F external catheter (arrow) was placed for biliary drainage before placement of the ¹²⁵I seed strands and stents; B: The stent delivery systems and ¹²⁵I seed strands (arrow) were advanced over the wires to the sites of the obstruction. The stents were then deployed simultaneously, followed by placement of the ¹²⁵I strands; C: Abdominal CT at 3 mo after the procedure. The results showed mild dilatation of the intrahepatic bile ducts (arrow), and the stents remained patent. CT: Computed tomography.
