21 kwi 2024 · The veins of the pelvis drain deoxygenated blood and return it to the heart. There are three major vessels involved in the venous drainage of the pelvis - the external iliac vein, internal iliac vein and common iliac vein (these correspond the major major pelvic arteries).
3 lis 2023 · The internal iliac vein arises superiorly to the greater sciatic foramen. It is formed by the coalescence of several extrapelvic and pelvic veins; Its extrapelvic tributaries are the superior gluteal, inferior gluteal, internal pudendal and obturator veins.
25 maj 2023 · The common iliac vein is formed by the unification of the internal and external iliac veins. The external iliac vein drains the lower limb, and the internal iliac vein drains the gluteal region and pelvic viscera. The unification of the two common iliac veins forms the inferior vena cava.
The internal iliac vein (hypogastric vein) begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.
The internal iliac vein is a blood vessel that passes into the pelvis alongside the internal iliac artery, dividing into posterior and anterior divisions at the upper margin of the greater sciatic foramen.
27 wrz 2023 · Like the arterial analogues, the external iliac vein primarily drains the lower limbs, while the internal iliac vein drains the pelvic viscera, walls, gluteal region and perineum. In most instances, the major veins are mirror images of their arterial counterparts.
5 mar 2023 · The internal, external, and common iliac nodes drain the pelvis and its contents, while the inferior epigastric vein empties into the external iliac vein. For example, the contents of the pelvic viscera are drained by the internal iliac nodes while being surrounded by branches of the internal iliac vessels.
