Q2- A large tumor mass impinges on the splenic artery and its branches as the artery passes out from below the gastric curvature of the stomach . Branches of which of the following arteries would most likely get affected by the pressure on the splenic artery?
a- left gastric
b-left gastroepiploic
c-right gastric
d-right gastroepiploic
e-short gastric

Mytime,I believe in your Anatomy qs the right answer to 2nd q is E "short gastric artery" not B.
Left gastroepiploic artery has anstomotic connections with right gastroepiploic artery , so the blood supply is not affected while short gastric artery does not have any anastomoses so the area supplied by short gastric artery is affected more.
Reasons i still choose B-left gastro epiploic..
1- The obstruction is +nt at artery's exit frm behind stomach n till then, short gastrics have already gone out
2- Short gastrics anastomose wth left gastro epiploic n r major sources of compensatory blood supply to spleen frm sup.mesenteric when we occlude splenic artery to treat aneurysms.

Yeah, you are right indi that short gastric arteries anstomose with left gastroepoploic and left gastric arteries but I am not sure if this anstomosis is as strong as between the left and right gastroepiploics ? I mean is the anastomosis strong enough to keep the blood supply intact inspite of short gastrics being impinged by a big tumor ? Please explain.

Short gastric arteries (four to five): arise from the distal end of the splenic artery or its splenic branches and pass to the fundus of the stomach.

I think the questions wants us to know that whether we know th ebracnhes of the splenic artery cos they have asked the ARTERIES Affected by Pressure on Splenic Artery. not he Anastomoses of the Artery or arteries in a event of such pressure. by looking at the diagram i think the only artery as i have chked both Gray's Anatomy n KLM they both say that Short gastric arteries r the last branches of Splenic And Also they say that the origin of Left gastric -epiploic n short gastric is almost near each other

Thanks nnl . You are right that they are asking the branches of splenic artery but the left gastorepipoic and all of the short gastrics are the branches of splenic artery . So which ones are most likely to be affected ? I was thinking that the ones with less anastomotic connections will be affected more than the one with a rich anastomosis
I am looking at the atlas right now and according to it left gastroepiploic originates behind the stomach and short gastrics originate just after this near the spleen.
Oh well, what ever .... lets finish it and get back to books.

Got it guys.. Splenic A. compressed below curvature probably means behind the stomach..which is below relatively..so the most effected wud be Short gastric A. which gets it's blood supply from the Splenic! Viola'! It took four geniuses to come up with one simple ans! There's still a future for us, I guess! Cud have been more ppl. Thanks for the dia NNL..been looking for that one for long. And the eye-opener! Am glad i posted these qs. Discussion over! Next round plz.!
SOMEONE PLZ, ATTEMPT THOSE ENDO. QS BEFORE THE WHIP COMES OUT, YET AGAIN! 
They are on the prev. page over the anat. set!

i think the Answer shud be Short gastric artery for one reasononly As the Lt. Gastroomental artery is largeer than Short Gastric the artery most likely to suffer is short gastric cos as INDI rightly said it will receive anastomoses but in particular the diameter of the artey gives us a clue abt it. Short Gastric is not gonna have any help is a little branch hence its likely for it to suffer more. If in th eend they hadnt mentioned that the tumor is hitting splenic then the answer wud be Lt. gastroepiploic cos its the only branch which runs along the greater curvature but they asked which branch in particular if Splenic arter is compressed which changes the Scenario

Yup so will probably start having a splenic infart senario here if not for that LGE! Thank u!! good to know we all got it wrong, one way or the other! Doesn't feel lonely anymore!

Branches of which of the following arteries would most likely get affected by the pressure on the splenic artery?
Now i m beginning to think that the Q doesn't ask us abt anastomosis at all... or it would be.. "parts supplied by which of these would undergo max damage"
even otherwise.. considering the anastomosis.. short gastric arteries are multiple small branches n not a single one... n as if the LGE is ok, they ll have blood flow due to anastomosis... LGE is single n more likely to be compressed by tumors.
I m thoroughly confused but my gut feeling says..its B left gastroepiploic..
PS- The gut ought to know.. After all.. these arteries supply it!!

Hey USMLE4ME u finished resp? What u doing now...We'll be starting renal!
Guys..another one.....
1. the coz of pneumonia in immunocomprimised pts.!? u know this one too! think!!!!!! Ah ha! C!
2. Most common gram negative pneumonia?
3. Most common pneumonia in neutropenics?
4. How do u do the rapid diagnosis in legionella infection?
i'll post some more as I read.... this is just to help us recall! Others can do the same vingettes not always reqd.
