Recommendations
14
Gastroduodenal Artery Aneurysm (GDAA) and
Pancreaticoduodenal Artery Aneurysm (PDAA)
Recommendation
Grade/
LOE
3.3 In patients with appropriate anatomy, we suggest transcatheter
embolization with liquid embolic agents as a treatment option for both
GDAA and PDAA.
2-C
3.4 In patients with suitable anatomy, we suggest flow-diverting,
multilayered stents as a treatment option for GDAA and PDAA,
although these have not been adequately studied to be recommended as
a primary treatment modality.
2-C
3.5 In patients with nonruptured aneurysms, we suggest open surgical
reconstruction if needed to preserve flow.
2-B
3.6 In patients with concomitant stenosis or occlusion, we suggest celiac
artery reconstruction.
2-B
4. De novo screening and screening for concomitant aneurysms
4.1 In patients with median arcuate ligament syndrome, we suggest
screening for GDAA or PDAA with CTA or duplex ultrasound.
2-C
5. Follow-up and surveillance
5.1 In patients status post treatment of GDAA and PDAA, we recommend
follow-up imaging aer endovascular treatment of GDAA and PDAA
to rule out persistent flow through the aneurysm sac.
