Abstract

Purpose: To evaluate the technical feasibility and safety of dual lumen balloon microcatheter Onyx embolization in peripheral interventions. Material and methods: Between January 2013 and September 2014 , seven patients underwent Onyx embolization through a double lumen balloon microcatheter. Onyx was injected as solely agent in three patients with chronic hemoptysis, two patients with life threatening organ bleeding and one with a rejected kidney graft. In one patient with a liver arterioportal fistula, a combination of coils and onyx was used through the same system. In addition to this technical implementation, we also describe three cases where an anchoring tecnhique were used in tortuous arterial anatomies in order to place micro and guide catheters in a stable position. Results: All the Onyx embolizations were completed and well tolerated. During the Onyx embolization, no reflux was noted and inmediate forward flow was identified. Technical success was 100%. The clinical outcome of the patients was satisfactory with no (peri/postprocedural) complications Conclusion: Double-lumen balloon microcatheter Onyx embolization is feasible and safe in peripheral interventions, lowering the potential complications related to reflux or Onyx migration.
