welpdedelpSuperior rectal comes from the inferior mesenteric vein which comes from the splenic vein --> portal veins
Thus, this dude had cirrhosis so it would "back-up" into the superior rectal vein.

lilyothomasburton, so are they asking what vessels do internal hemorrhoids directly drain into? The order is Superior rectal vein--> Inferior mesenteric vein--> portal vein.+2019-09-13T14:25:04Z
thomasburtonYes exactly, so they do eventually reach IMV but not 'directly'+2019-09-18T14:12:46Z
dubywowBecause the wording sucks. It's a confusing way to word the question. I too was confused what direct tributaries was referring to and chose Inferior mesenteric because I suck and also because this question sucks.
Really its asking where are the hemorrhoids? They are on/from the superior rectals even though those veins feed to Inferior mesenteric. +2019-10-13T16:38:44Z
