during weeks 4 to 9 of intrauterine life.

Superior Mesenteric Artery
Aneurysms: Is Presence An Indication For Intervention?
Ligation of both the coeliac axis and superior mesenteric artery
with survival of the patient.
The precise aetiology of the bleed from the superior mesenteric artery
pseudoaneurysm cannot be fully determined.
Fewer than 2% of cases included ovarian cysts, superior mesenteric artery
syndrome, gallstones, chronic appendicitis, or hydronephrosis.
Aortic stentgrafts are available in various configurations: tube stentgrafts, tapered stentgrafts (aorto-uniiliac), bifurcated stentgrafts ('Y' or trouser graft), fenestrated stentgrafts (with a scallop for the superior mesenteric artery
and two reinforced fenestrations for renal artery stents), and branched stentgrafts (with side-arm/s for additional endografting to the mesenteric, renal and supra-aortic vessels) (Fig.
They are benign but can obstruct important structures such as the superior mesenteric artery
, resulting in significant morbidity and even mortality.
3,4) Given that the majority of extra-adrenal intra-abdominal paragangliomas occur in the superior para-aortic region, (7) it is not surprising that normal paraganglionic tissue has been described close to the duodenum and at the root of the superior mesenteric artery
The sidehole pattern and unique tip shape allow for opacification of the aorta from distal vessels - without obscuring the image by filling of the superior mesenteric artery
William Norwood, the surgeon who operated on the patient, opined that she may have had in infarct (an area of tissue death due to a local lack of oxygen) of the superior mesenteric artery
, the main blood supply to the intestines.
