Q

Budd-Chiari syndrome demonstrates thrombosis of the

A

22
Q

The vessel that arises from the anterior aortic wall and takes a parallel course to the aorta is the:

A

SMA

(The superior mesenteric artery (SMA) and the celiac axis arise from the anterior aortic wall; of these, only the SMA takes a parallel course to the aorta)

23
Q

Which one of the following statements is false for a patient with renal vein thrombosis?

b. Renal size increases in the acute phase.
c. Doppler flow increases.

A

Doppler Flow increases

24
Q

Select one:
a. The portal vein enters the lesser omentum.
b. The portal vein is formed anterior to the pancreas.
c. The portal vein drains blood out of the gastrointestinal tract.
d. The portal vein has an anastomosis with the esophageal veins, rectal venous plexus, and superficial abdominal veins.
