  • Strategies for the Management of SVC Stent Migration into the Right Atrium
    CardioVascular and Interventional Radiology, 2007
    Co-Authors: J. D. Taylor, E D Lehmann, A A Nicholson, David Kessel, I R Robertson, J G Pollock, A.-m. Belli, Robert A Morgan
    Abstract:

    Purpose Stent Migration into the right atrium is a potentially fatal complication of Stenting in the venous system and is most likely to occur during the treatment of superior vena cava obstruction. Endovascular approaches that can salvage this hazardous situation are described and the keys to successful treatment are highlighted. Materials and Methods Four different strategies are reviewed: (1) snaring the Stent directly, (2) angioplasty balloon-assisted snaring of the Stent, (3) guide wire-assisted snaring of the Stent, and (4) superior vena cava-to-inferior vena cava bridging Stent. Results These techniques have been employed in the successful management of four cases. No short- or long-term complications as a result of these maneuvers have been identified. Additional treatment of the underlying disease was possible at the same time in each case. Conclusion We conclude that prompt management of right atrial Stent Migration is essential and can be successfully achieved by a variety of “bale-out” techniques which are within the technical range of most interventional radiologists.

  • Superior vena cava Stent Migration into the pulmonary artery causing fatal pulmonary infarction.
    CardioVascular and Interventional Radiology, 2010
    Co-Authors: Girija Anand, Conrad R. Lewanski, Steven A. Cowman, James E. Jackson
    Abstract:

    Migration of superior vena cava (SVC) Stents is a well-recognised complication of their deployment, and numerous strategies exist for their retrieval. To our knowledge, only three cases of Migration of an SVC Stent to the pulmonary vasculature have previously been reported. None of these patients developed complications that resulted in death. We report a case of SVC Stent Migration to the pulmonary vasculature with delayed pulmonary artery thrombosis and death from pulmonary infarction. We conclude that early retrieval of migrated Stents should be performed to decrease the risk of serious complications.

  • endoscopic suturing for the prevention of Stent Migration in benign upper gastrointestinal conditions a comparative multicenter study
    Endoscopy, 2016
    Co-Authors: Saowanee Ngamruengphong, Reem Z Sharaiha, Amrita Sethi, Ali Siddiqui, Christopher J Dimaio, Susana Gonzalez, Jennifer Im, Jason Rogart, Sophia Jagroop, Jessica L Widmer
    Abstract:

    Background and study aims: Fully covered self-expandable metal Stents (FCSEMSs) have increasingly been used in benign upper gastrointestinal (UGI) conditions; however, Stent Migration remains a major limitation. Endoscopic suture fixation (ESF) may prevent Stent Migration. The aims of this study were to compare the frequency of Stent Migration in patients who received endoscopic suturing for Stent fixation (ESF group) compared with those who did not (NSF group) and to assess the impact of ESF on clinical outcome. Patients and methods: This was a retrospective study of patients who underwent FCSEMS placement for benign UGI diseases. Patients were divided into either the NSF or ESF group. Outcome variables, including Stent Migration, clinical success (resolution of underlying pathology), and adverse events, were compared. Results: A total of 125 patients (44 in ESF group, 81 in NSF group; 56 benign strictures, 69 leaks/fistulas/perforations) underwent 224 Stenting procedures. Stent Migration was significantly more common in the NSF group (33 % vs. 16 %; P = 0.03). Time to Stent Migration was longer in the ESF group (P = 0.02). ESF appeared to protect against Stent Migration in patients with a history of Stent Migration (adjusted odds ratio [OR] 0.09; P = 0.002). ESF was also significantly associated with a higher rate of clinical success (60 % vs. 38 %; P = 0.03). Rates of adverse events were similar between the two groups. Conclusions: Endoscopic suturing for Stent fixation is safe and associated with a decreased Migration rate, particularly in patients with a prior history of Stent Migration. It may also improve clinical response, likely because of the reduction in Stent Migration.

  • optimal prevention and management of proximal ureteral Stent Migration and reMigration
    The Journal of Urology, 2001
    Co-Authors: Rodney H. Breau, Richard W. Norman
    Abstract:

    Purpose: We evaluated issues associated with proximal ureteral Stent Migration and reMigration, including causes and management, and the predictability of ureteral length.Materials and Methods: All proximal ureteral Stent Migrations that occurred from January 1997 to March 2000 were reviewed. Characteristics and treatment of the 33 patients with proximal ureteral Stent Migration were compared with those of 66 randomly selected controls who did not have Stent Migration. We also analyzed a subgroup of 6 cases of reMigration.Results: Of the ureteral Stents 2% migrated proximally. Mean height was greater in patients with versus without a migrated Stent (p = 0.028). The Stent-to-ureter length ratio was lower in the migrated than in the nonmigrated group (p <0.0001). Patient height and side of Migration were significant predictors of ureteral length (R2 = 0.3511, p <0.0001 and 0.0007, respectively). Of the patients who required continued ureteral Stenting migrated Stent management included placement of a longer...
