Summary

The Spinnaker 1.8F microcatheter can rupture during Ethibloc embolizations with Ethibloc/Lipiodol mixtures 1:1 or 1:2 after more than four injections. The Spinnaker 1.5F is unsuitable for Ethibloc embolization, recommending guidewire-directed microcatheters instead.

Area of Science:

  • Interventional Radiology
  • Vascular Surgery
  • Biomedical Engineering

Background:

  • Endovascular embolization is a minimally invasive procedure used to block blood flow to specific areas.
  • Microcatheters are essential tools for delivering embolic agents during embolization procedures.
  • The Spinnaker microcatheter is a flow-directed device used in endovascular interventions.

Purpose of the Study:

  • To evaluate the in vitro performance and safety of the Spinnaker microcatheter during endovascular embolizations using Ethibloc as the embolic agent.
  • To determine the rupture and occlusion rates of Spinnaker 1.8F and 1.5F microcatheters with different Ethibloc/Lipiodol mixtures.
  • To identify optimal conditions for using Spinnaker microcatheters with Ethibloc or recommend alternative devices.

Main Methods:

  • In vitro testing of 50 Spinnaker 1.8F and 10 Spinnaker 1.5F microcatheters.
  • Use of Ethibloc and Lipiodol (E/L) mixtures at ratios of 1:1, 1:2, and 1:3 as embolic agents.
  • Microcatheters were subjected to up to ten injections, with rupture and occlusion events meticulously recorded.

Main Results:

  • Spinnaker 1.8F microcatheters ruptured in 45% of cases with E/L 1:1 and 20% with E/L 1:2, primarily after the fifth injection.
  • No ruptures occurred with Spinnaker 1.8F using E/L 1:3, or with fewer than four injections of E/L 1:1 or 1:2.
  • All Spinnaker 1.5F microcatheters ruptured when used with E/L 1:2 or 1:3 mixtures.

Conclusions:

  • The Spinnaker 1.8F microcatheter demonstrates susceptibility to rupture with Ethibloc/Lipiodol mixtures (1:1, 1:2) beyond four injections.
  • The Spinnaker 1.5F microcatheter is not suitable for Ethibloc embolization due to high rupture rates.
  • Guidewire-directed microcatheters are recommended for Ethibloc embolizations to ensure procedural safety and efficacy.
