Fluid-dynamic control microcatheter used with glue: preliminary experience on its feasibility and safety

Purpose: To evaluate feasibility, safety, and success of peripheral embolization procedures carried out using anti-reflux microcatheter with N-butyl-cyanoacrylate (NBCA) as an embolic agent. Methods: We retrospectively described 11 patients that suffered from active bleeding in different body districts, who underwent embolization procedure using SeQure microcatheter (Guerbet, France) with NBCA glue (Glubran II, GEM Italy) as an embolic agent. The treatments required NBCA volumes ranged from 0.1 to 0.6 mL, with different dilutions with ethiodized oil (Lipiodol, Guerbet, France), depending on the entity of the bleeding. Technical success, clinical success, and complications were evaluated. Results: The procedures were successfully concluded in the totality of the patients, achieving full technical and clinical success. In one patient (9.1%), a small upstream of embolic material was encountered, without any consequence. Conclusion: This preliminary experience shows that the use of SeQure is feasible and safe with NBCA.
