2025年2月13日 · The veins of the abdomen drain deoxygenated blood and return it to the heart. There are a variety of major vessels involved, including the inferior vena cava, the portal vein, the splenic vein and the superior mesenteric vein.

2015年12月26日 · The ileocolic vein is formed by the union of the anterior and posterior cecal veins, appendicular veins, the last ileal vein, and a colic vein. The ileocolic vein can anastomose with the ileal veins and right colic vein and it eventually drains into the SMV on the right.

2023年11月3日 · This article will discuss the anatomy of abdominal arteries and veins, as well as topographical approach to the abdominopelvic vasculature.

2023年3月5日 · The two principal venous tributaries in the pelvis are the internal and external iliac veins, while the gastric veins dominate the abdomen. The union of the internal and external iliac veins creates the common iliac vein, while the inferior epigastric vein drains into the external iliac vein and anastomoses from the superior epigastric vein.

2024年6月2日 · The key portal venous anatomy on CT starts with the mesenteric veins – specifically the superior mesenteric vein (SMV) which joins with the splenic vein to form the portal vein. This relationship is often best seen on coronal images.

In this section, learn more about the vasculature of the abdomen- the arterial supply and the venous drainage.

2024年10月7日 · This chapter deals with the normal and variant anatomy of the abdominal venous system and the main types of pathology detectable by ultrasound. Because of their embryology, the inferior vena cava and its tributaries and the mesenteric and extrahepatic portal venous systems are discussed in the same chapter.
