Question

Explain briefly:
Capillaries arising from the mesentric and splenic artery do not unite to form the corresponding veins.​

Answer 1

Answer:

Explanation:

The splenic artery is the largest and most tortuous branch of the celiac trunk. After originating from the celiac trunk, the artery courses laterally, posterior to the stomach, and along the superior border of the pancreas. At the tail of the pancreas, the artery divides into its terminal branches that enter the hilum of the spleen.1 Variations in origin, course, and branching of visceral arteries, particularly those of the celiac trunk and superior mesenteric artery (SMA), are documented in medical literature.2 However, splenic artery origin from the SMA occurs infrequently. For certain abdominal surgeries, it is imperative to know the anatomic location of the splenic artery. An unforeseen variant in splenic artery anatomy could lead to inadvertent iatrogenic injury, prolonged operative time, and/or increased blood loss.
