Trunk vessels (aorta, vena cava, abdominal branches)
Inferior epigastric veins
Venae epigastricae inferiores
- Origin
- Arise from the periumbilical venous plexus in the rectus sheath
- Insertion
- Descend accompanying the inferior epigastric artery to drain into the external iliac vein
- Function
- Drains the lower anterior abdominal wall into the external iliac vein and IVC system
- Innervation
- Sympathetic vasomotor fibers
- Movement & chain
- Low-pressure venous drainage
- Palpation
- Not palpated directly
- Clinical
- Deep collateral drainage pathway in portal hypertension and IVC occlusion.
- Segmental innervation
- T10-L1 dermatomes
- In clinical practice
- Avoidance of vascular injury in lower abdominal laparoscopic ports
- Region in the model
- Trunk vessels (aorta, vena cava, abdominal branches)
