obturator vein
Noun 1. A specific vein of the pelvis: The obturator vein is a blood vessel that is formed by the merging of smaller veins draining the hip joint and the muscles of the inner thigh. It carries deoxygenated blood from these areas and empties into the internal iliac vein, which is a major vein in the pelvic region.
The term "obturator vein" is used exclusively in anatomical, medical, and surgical contexts to identify this specific structure. * During the pelvic dissection, the surgeon carefully identified and ligated the obturator vein. * The anatomy textbook illustrated how the obturator vein connects the thigh muscles to the internal iliac vein.
- Clinical Relevance: The obturator vein is of particular importance in surgical procedures involving the pelvis, such as hernia repairs or pelvic lymph node dissections, as it must be identified to avoid significant bleeding.
- An injury to the obturator vein during surgery can lead to a hematoma.
- Venous plexus: A network of veins. The tributaries forming the obturator vein are often described as part of an obturator venous plexus.
- Internal iliac vein: The larger pelvic vein into which the obturator vein drains.
There are no true synonyms for this specific anatomical term. It may be referred to descriptively as: * A tributary of the internal iliac vein (describing its function).
The word "obturator" alone can refer to other anatomical structures: * Obturator foramen: A large opening in the hip bone. * Obturator nerve: A major nerve supplying the inner thigh. * Obturator artery: The artery that accompanies the vein through the obturator canal.
The term "obturator vein" refers specifically to the blood vessel and not these other structures.
- a vein formed by the union of tributaries that drain the hip joints and thigh muscles; empties into the internal iliac vein
