Fixing Visceral Pseudoaneurysms with N-Butyl Cyanoacrylate Glue
The endovascular repair of visceral pseudoaneurysms encompasses a heterogenous set of technical challenges that have been well described using conventional techniques of coil embolization. In the majority of cases, classic coil embolization to exclude the PSA is both technically achievable and well tolerated. However, in a minority of cases, this approach may not be possible secondary to anatomic challenges. Alternative techniques to overcome these challenges include covered stent placement and stent-assisted coil embolization. With NBCA, the interventionalist has yet another tool to overcome these often challenging cases. The authors’ description and figures highlighting potential complications associated with use of NBCA for PSA repair highlight the need for the operator to be familiar and experienced in the use of this embolization agent prior to its use in these challenging circumstances.
