1 Novel use of the Surefire antireflux device in subtotal splenic embolization 
John Chung, MD, Richard Cormack, MD, Roshni Patel, MBBS, Avnesh Thakor, MD, PhD, Darren Klass, MD, PhD, David Liu, MD  Journal of Vascular Surgery Cases  Volume 1, Issue 4, Pages (December 2015) DOI: /j.jvsc Copyright © 2015 The Authors Terms and Conditions

2 Fig 1 Splenic artery angiographic appearances before any embolization (a) and after administration of half a vial of 100- to 300-μm Bead Block particles through an end-hole catheter (b), showing apparent subtotal splenic embolization with truncation of distal splenic branches and proximal reflux into short gastric arteries (arrow). Positioning of a Surefire antireflux infusion catheter into the splenic artery undeployed (c) and with the expandable tip deployed (d; arrow). Residual small dissection in the mid splenic artery (arrowhead). Journal of Vascular Surgery Cases 2015 1, DOI: ( /j.jvsc ) Copyright © 2015 The Authors Terms and Conditions

3 Fig 2 a, Angiographic appearance during Surefire infusion system-aided administration of an additional 2.5 vials of 100- to 300-μm Bead Block particles and 1 vial of 300- to 500-μm Embosphere particles. No reflux was seen into short gastric arteries. b, Axial image from postembolization contrast-enhanced cone beam computed tomography (CT) performed on the procedural table, showing persistent patchy splenic parenchymal enhancement compatible with subtotal splenic embolization. c, Axial image from a preprocedural contrast-enhanced CT study revealing a large subcapsular splenic hematoma. d, Axial image from a contrast-enhanced CT study obtained 5 days after embolization shows substantially reduced splenic parenchymal enhancement (arrow), although some residual viable splenic tissue was depicted, indicating successful subtotal splenic embolization.
