1 Timeline of data

The data presented here are from fenestrated or branched EVAR performed between 17 December 2009 and 24 April 2023 and comprise 83 cases.

Both urgent and elective cases are included.

2 Fenestrations and branches - counts

In general, fenestrations are preferred to branches but urgent cases are almost exclusively treatable only with branches.

Stenting all four vessels is the most common scenario.

Largely for availability reasons, choice of stent-graft moved to VBX when Atrium (V12 Advanta) became more unreliable to source.

Size of some stent-grafts could not be obtained (n = 7)
Splenic artery was stented once; this is not included
CA = coeliac axis, LRA & RRA = left and right renal arteries, SMA = superior mesenteric artery
In some situations, a larger stent (eg. 7 mm VBX) is deliberately under-inflated in a smaller vessel as the 7 mm VBX will flare more reliably and easily than the 6 mm device

These all reflect imaging-proven stent-graft occlusion.

Splenic artery is again omitted as it was only stented once
Of note, the case in which both coeliac axis and splenic artery were individually stented resulted in coeliac axis fenestration occlusion and splenic fenestration patency
