Overview of the anatomy of the common, external, and internal iliac veins, their tributaries, and their roles in the vascular system.

Common Iliac Vein:
Formed by the confluence of the internal and external iliac veins at the level of L4-L5 vertebrae.
No valves present in the common iliac veins.
Tributaries:
- Ascending lumbar vein (anastomoses with azygos and hemiazygos veins).
- Median sacral vein (opens into the left common iliac vein).
- Iliolumbar veins (could open into the internal iliac vein).

External Iliac Vein:
Continuation of the common femoral vein starting at the inguinal ligament.
Tributaries:
- Inferior epigastric vein (drains the anterior abdominal wall, anastomoses with superior epigastric vein).
- Deep circumflex iliac veins (collects blood from the iliac region).

Internal Iliac Vein:
Divided into two divisions with parietal and visceral tributaries.
Parietal Tributaries:
- Superior and inferior gluteal veins (drain gluteal muscles).
- Obturator vein (drains medial thigh muscles).
- Lateral sacral veins (form sacral venous plexus).
Visceral Tributaries:
Categorized into male, female, and others.
- Rectal Venous Plexus: Drained by superior, middle, and inferior rectal veins.
- Vesical Venous Plexus: Drains urinary bladder.
Male: Fuses with prostatic venous plexus.
Female: Surrounds bladder and drains urethra.
- Uterine and Vaginal Venous Plexuses (female).
- Internal Pudendal Vein: Drains various structures near the pelvis.
