external iliac vein
The surgeon carefully identifies the external iliac vein during the procedure.
Noun: A major blood vessel that is the continuation of the femoral vein in the pelvis. It carries deoxygenated blood from the lower limb towards the heart. It unites with the internal iliac vein to form the common iliac vein.
The term "external iliac vein" is used in anatomical, medical, and surgical contexts to describe a specific part of the venous system. * The external iliac vein runs alongside the external iliac artery. * Surgeons must be careful not to damage the external iliac vein during pelvic procedures. * A deep vein thrombosis (DVT) can sometimes occur in the external iliac vein.
- Clinical Context: In medical imaging and diagnosis, the patency (openness) of the external iliac vein is crucial for proper blood return from the leg. Conditions like May-Thurner syndrome involve compression of this vein.
- Surgical Landmark: The external iliac vein serves as an important anatomical landmark during procedures like hernia repairs and vascular surgeries.
- Common iliac vein (noun): The vein formed by the union of the external and internal iliac veins.
- Internal iliac vein (noun): The vein that drains blood from the pelvic organs and joins the external iliac vein.
- Femoral vein (noun): The vein in the thigh that continues upward to become the external iliac vein.
- Iliac (adjective): Pertaining to the ilium (hip bone) or the nearby anatomical structures, such as in , .
- There are no true synonyms for this precise anatomical term. In general descriptive language, it may be referred to as a major pelvic vein or a venous trunk of the lower limb, but these are not exact synonyms.
- Venous drainage of the lower limb: The process by which blood returns from the leg, involving the external iliac vein.
- Iliac vein compression: A condition where an artery presses on a nearby iliac vein (often the left common iliac vein), potentially affecting the external iliac vein's outflow.
