Endovascular Treatment of Angio-Seal™-Related Limb Ischemia-Primary Results and Long-Term Follow-Up

Objectives: To investigate primary success rates and long term follow-up of endovascular treatment of AngioSeal (TM)-related limb ischemia. Background: Current knowledge on optimal therapy of ischemic complications following application of AngioSeal (TM) is limited. Methods: A single-center prospectively maintained database was retrospectively interrogated and AngioSeal (TM) related complications requiring endovascular treatment over an 8-year-time period was identified. Results: Fifteen patients fulfilling the inclusion criteria were identified, resulting in an approximated incidence of 0.26% of all devices implanted at our institution. In all cases, the complication was managed successfully in the absence of complications. Eleven patients were treated with balloon angioplasty (PTA) and four with stent implantation because of suboptimal PTA results. Twelve patients were available for noninvasive vascular follow-up examination for a median time of 40 months postinterventionally. Only two patients needed a second intervention consisting of balloon angioplasty due to symptomatic restenosis. At final follow-up all patients were asymptomatic with no relevant restenosis. Conclusion: Endovascular treatment for AngioSeal (TM)-related limb ischemia with or without stent implantation results in an excellent immediate and long-term clinical and hemodynamic outcome.
