21 Products listed may not be available in all markets. GORE ®, VIATORR ®, and designs are trademarks of W. L. Gore & Associates. © 2010, 2013 W. L. Gore & Associates, Inc. Case Study: TIPS in a Small Hard Liver Clinical Challenge: 52 year old female with autoimmune hepatitis complicated by intractable ascites, lower extremity edema and esophageal varices. MELD score of 9 (Figure 1). Materials and Methods: Implantation of a 10 mm diameter x 6 cm long (lined portion) GORE ® VIATORR ® TIPS Endoprosthesis to treat her portal hypertension and sequela (Figure 2). Physician Comments: Goal was to reduce patient’s ascites and subsequently her lower extremity edema. TIPS was technically successful (Figure 3). Liver was extremely small and “rock hard”. However, the device could be advanced and deployed without difficulty. TIPS Tip: For small hard livers it is essential to use a reinforced 10 Fr sheath to prevent kinking below the hub. Case Study Information Provided by: James Caridi, MD, Irvin Hawkins, MD, Shawn Meader, MD.

Case Study: Recurrent Hepatic Vein Stenosis in a TIPS Clinical Challenge: 50 year-old male with Child-Pugh liver disease related to prior alcohol use underwent TIPS for recurrent variceal hemorrhage six years previously. Shunt was revised with balloon agioplasties and repeated stent placements three times due to stenoses and recurrent hemorrhage (Figure 1). Device Solution: Implantation of a 10 mm diameter x 6 cm long (lined portion) GORE ® VIATORR ® TIPS Endoprosthesis to treat recurring TIPS outflow stenosis(Figure 2). At 50 month clinical follow-up, the shunt remains, patent, portal pressures remain low, and no interventions have been needed. Patient is free of recurrent symptoms (Figures 3 – 5). Physician Comments: The ePTFE-lined stent endoprosthesis provided a solution to the patient’s recurring TIPS failure. Liver disease has remained mild and stable. Ultimate need for liver transplantation is expected to be very low. TIPS Tip: Using the GORE ® VIATORR ® TIPS Endoprosthesis in revision situation can be more challenging than in a de novo case. Location of intrahepatic portal vein must be precisely identified, so as to avoid lining the intrahepatic portal vein with graft material. Case Study Information Provided by: Ziv Haskal, MD, FSIR.

24 Products listed may not be available in all markets. GORE ®, VIATORR ®, and designs are trademarks of W. L. Gore & Associates. © 2010, 2013 W. L. Gore & Associates, Inc. Implantation Tips for Success: Step 1 Pre-dilate Parenchymal Tract All balloon-dilated segments should be covered by the device post-deployment. The entire de novo tract from the liver parenchyma / portal vein junction to hepatic vein / IVC ostium should be covered by the lined portion of the GORE ® VIATORR ® TIPS Endoprosthesis. To enhance tactile feel and to minimize the potential for pulling the bar chain-link portion of the device into the liver parenchyma, use an undersized balloon from the selected device diameter to pre-dilate the de novo parenchymal tract.

Implantation Tips for Success: Step 3 Device Selection Select the appropriate device (diameter and length) from the sizing table. Select the appropriate accessory equipment. Table 1: Dimensions and Recommended Accessories (12 mm device is not available in all countries) 1 Lengths may vary by ± 0.5 cm. 2 A stiff guidewire, having a length of at least 180 cm and a maximum diameter ≤ 0.038" (0.97 mm), is required. Delivery catheter working length is 75 cm for all endoprosthesis configurations. 3 Introducer sheath length must be sufficient to be delivered into the portal circulation by ≥ 3 cm. It is recommended that a wall-reinforced TIPS introducer sheath (such as COOK ® FLEXOR ®, CHECK-FLO ® II Introducer Sheath. or equivalent) with an integral radiopaque marker band and a length of approximately 40–45 cm be used. 4 The same balloon dilatation device can be used for TIPS dilatation and dilatation of the endoprosthesis following implantation.

Implantation Tips for Success: Step 7 Consider utilizing a two-operator approach to device deployment. Fluoroscopic guidance is required. While maintaining the delivery system position, retract the sheath and deploy the chain-link segment of the device into the portal vein. Completely retract the hemostatic introducer sheath beyond the trailing end of the endoprosthesis and into the IVC: –For de novo procedures, once the chain-link portion is deployed (3 cm) into the portal vein, gently pull back on the delivery catheter until resistance is felt. This will seal the distal end of the covered device portion to the liver parenchyma / portal vein junction. Deployment

Implantation Tips for Success: Step 7 continued... While maintaining delivery system traction and the delivery system position relative to the sheath, keep the delivery system straight and loosen the GORE ® SIM ‑ PULL Deployment System knob. –Pull the deployment knob with smooth, controlled tension. –Do not attempt repositioning during deployment. Deployment NOTE: Do not attempt to recapture once deployment is initiated. Device cannot be repositioned once deployment is complete. For de novo cases: Advance distal end of introducer sheath 3 cm into portal vein. For revision cases: Align distal end of introducer sheath to distal end of stent being revised. Do not advance chain-link beyond end of bare stent as pulling back the GORE ® VIATORR ® TIPS Endoprosthesis may result in device or deployment line entanglement on the distal end of bare stent. Exercise care when positioning device while patient is breathing. GORE ®, SIM-PULL, VIATORR ®, and designs are trademarks of W. L. Gore & Associates. © 2010, 2013 W. L. Gore & Associates, Inc.

Implantation Tips for Success: Step 10 Completion Imaging Confirm positioning and patency of device. NOTE: If placing a second endoprosthesis to provide adequate length coverage, ensure ≥ 2 cm of lined graft-to-lined graft overlap of the telescoping devices. Take final PSG measurement and re-balloon as necessary. Use caution to not displace a deployed GORE ® VIATORR ® TIPS Endoprosthesis by re-introduction of an introducer sheath or working catheter back through the endoprosthesis.

35 Products listed may not be available in all markets. GORE ®, VIATORR ®, and designs are trademarks of W. L. Gore & Associates. © 2010, 2013 W. L. Gore & Associates, Inc. Conclusion A large body of published data demonstrate numerous clinical advantages of GORE ® VIATORR ® TIPS Endoprosthesis in treatment of patients with refractory ascites and variceal bleeding. The improvement of TIPS patency by using ePTFE-covered stents compared to bare metal stents is maintained over time with a decreased risk of hepatic encephalopathy and a decreased risk of death. The data demonstrate a clinical advantage of GORE ® VIATORR ® TIPS Endoprosthesis in treatment of patients with variceal bleeding and refractory ascites. Considering these results, the role of GORE ® VIATORR ® TIPS Endoprosthesis in the management of portal hypertension should be considered.
