>70% stenoses of the coeliac axis and superior mesenteric artery.
This patient had endovascular repair of an abdominal aortic aneurysm. Aliasing of the coeliac axis and proximal superior mesenteric artery was noted on colout Doppler assessment of the graft. B-mode imaging indicated significant stenoses of these vessels graded at >70% by spectral Doppler analysis.
The patient was asymptomatic for mesenteric ischaemia. However he is at risk as both the coeliac axis and superior mesenteric artery are stenosed.
Post-prandial scanning to assess for the level of velocity increase after food ingestion was not performed due to time constraints and lack of symptoms.
