Messi Mesentery

Luis, a 1st year medical student, is a self-proclaimed superfan of the world’s most popular sport, fútbol. He is devoted to Lionel Messi. Shortly after Messi announces his departure from FC Barcelona, Luis begins to experience crampy abdominal pain, vomiting, and constipation. He assumes these symptoms are related to the knowledge that his friends who rooted for Real Madrid would now show him no mercy.  However, his symptoms continue to progress, even after an evening with his pals when he experiences no stress because they spare him any taunts about Messi.  Luis visits the ED. A physical exam reveals distention, hyperactive bowel sounds, and a well-healed midline abdominal surgical scar. Imaging demonstrates dilated air-filled small bowel loops and minimal gas in the colon. The first-year colleagues are at a loss to determine which of his intestines are causing this mesenteric mess.

Question: Which of the following vessels most directly supplies the tissues impacted in this patient?

Postscript: I thank Alina Corona, M’4, at Georgetown Medical School for this question and the clinical scenario.
