Weight loss and abdominal pain in general pointed to intestinal ischemia of some sort and since most absorption of nutrients happens in the jejunum, ischemia there would cause weight loss. Jejunum is supplied by SMA
Bruit to me meant a larger vessel was blocked since to be able to hear it it has to be a pretty large vessel, SMA is one of the larger arteries listed
No liver symptoms (i.e. jaundice) so eliminated hepatic artery
If anyone has a better explanation please offer it.
deathcap4qtgreat explanation for not knowing the answer! You're right in that it has to do with a vessel of a larger size. Generally Celia, SMA or IMA. pt hx of atherosclerosis should be a big hint. FA 2019 pg 380.+3
nbmeanswersownersucksSMA is the MOST COMMON vessel involved in ischemic bowel disease.+2
baja_blastI reasoned this out by remembering that the Abdominal Aorta was the most common place for atherosclerosis and picking the only option that branches off immediately from there. Not sure if that's what they were going for but it got me to the right answer.+1
topgunberi think thats a great explanation ^, namely because its possible obstruction at the other vessels may not cause symptoms due to collateral circulation. SMA on the other hand, if stenosed, would have a number of regions with ischemia- not to mention its involved in a watershed area. +
an1I thought because this said severe pain after meals, it was hinting at gastric ulcers which was cause for the weight loss :(+

This is mesenteric artery stenosis causing postpranidal intestinal ischemia/angina. I definitely did not know this answering the question and I personally got to the answer by attempting to logically think through the symptoms:
