Case Series of Three Patients Undergoing Splenic Artery Aneurysm Embolization with Coils and n-Butyl 2-Cyanoacrylate (NBCA), Utilizing a Novel Polytetrafluoroethylene (PTFE)-Coated Microcatheter

Abstract

Case Series of Three Patients Undergoing Splenic Artery Aneurysm Embolization with Coils and n-Butyl 2-Cyanoacrylate (NBCA), Utilizing a Novel Polytetrafluoroethylene (PTFE)-Coated Microcatheter

Background: Splenic artery aneurysms (SAA) pose a significant risk due to potential rupture. N-butyl cyanoacrylate (NBCA) embolization is a common minimally invasive treatment, yet catheter performance can impact procedural success. This study evaluates the effectiveness and safety of the PTFE-coated Carry Leon NSX microcatheter in delivering NBCA during embolization of SAA.

Methods: A retrospective case series of patients undergoing NBCA embolization for SAA using the PTFE-coated Carry Leon NSX microcatheter. Procedural details, embolization success, complications, and follow-up outcomes were analyzed.

Results: The study includes three female patients: a 55-year-old, a 60-year-old, and an 80-year-old. Each patient presented with an SAA that was either incidentally discovered or demonstrated significant growth over time. The embolization procedure was successful, with complete occlusion of the aneurysm confirmed postembolization. Minimal complications such as mild splenic infarction or transient inflammatory responses were observed.

Conclusion: The PTFE-coated Carry Leon NSX microcatheter demonstrated high technical success and safety in NBCA-assisted embolization of SAA, suggesting it is a reliable tool for complex vascular interventions involving liquid embolics.
