Abstract
Three to six veins drain blood from the spleen and form the splenic vein, which lies at the T12 to L1 vertebral level (Sharma et al. 2012; Seidelmann et al. 1977). The caliber of the splenic vein is normally under 10 mm. A wider diameter can indicate an underlying pathology such as portal hypertension (Carneiro et al. 2019). The splenic vein runs from the splenic hilum in the splenorenal ligament medially from the spleen and posterior to the pancreas (Sharma et al. 2012). It passes along a groove on the posterosuperior surface of the pancreas, lying anterior to the left kidney and abdominal aorta and inferior to the splenic artery. The superior mesenteric artery separates it from the abdominal aorta. After running medially from the spleen, the splenic vein joins the superior mesenteric vein to form the portal vein in the right paraspinal area (Seidelmann et al. 1977). Specifically, this confluence occurs behind the neck of the pancreas (Kadel and Pandit 2020; Corness et al. 2006). Forty percent of the blood that drains into the portal vein flows from the spleen and pancreas through the splenic and other veins (Brennan et al. 2019).
