is this question asking what we physically pass through or by?

impostersyndromel1000  no, basically the question is testing if you know the branches of the abdominal aorta and which is closest to the renal (in this case, inferior to the renal arteries) +1  
impostersyndromel1000  what you are passing by would better answer your question actually +

Essentially, we're trying to get to the renal artery from the femoral.

We cross through internal iliac (B) already to reach the aorta.

Remember the branches of the abdominal aorta: Celia -> SMA -> Renal -> IMA (FA 2020 pg. 363)

Celiac (A) and SMA (C) is superior to the renal so cross them out.

We're left with testicular artery.





This question in it's essence is asking that after inserting the catheter in the femoral artery, which landmark should we use beyond which superiorly lies the renal artery, and the answer is the origin of the testicular artery. What a weirdly worded question though. :?

makinallkindzofgainz  I don't think it's worded that weirdly. The guide wire should be advanced superiorly just beyond the testicular artery to approach the right renal artery. +
