Cryoablation of the tissue ingrowth was performed using the CryoSpray (TruFreeze, Lexington, MA) Ablation (Figure 2) for 20 seconds, followed by placement of a 125 mm x 23 mm Wallflex FC-SEMS (Boston Scientific, Natick, MA) within the previously placed PC-SEMS (Figure 3) in order to promote tissue necrosis and permit subsequent removal of both stents.
