126. Veins of the thoracic wall, the upper part of the abdominal wall and the vertebral column.
Covers the veins of the thoracic wall, starting with intercostal veins: their anterior and posterior arrangement, and which vein each group drains into on the right and left sides, shown in tables. It then moves to the abdominal wall, listing the anterior superficial and upper veins by mnemonic-style groups and the posterior tributaries of the inferior vena cava. The final part describes the internal and external vertebral venous plexuses, the intervertebral veins and segmental drainage in the cervical, thoracic, lumbar and sacral regions.
Topic 21 of 36 in the MU Sofia syllabus for Anatomy (Cardiovascular system) (Medicine, Year 2). The free AceMed note covers it in 10 sections, about 470 words (4 min of reading), with 14 flashcards.

THORACIC WALL VEINS
Intercostal veins :
ABDOMINAL WALL VEINS
Anterior Abdominal Wall:
Posterior Abdominal wall:
VERTEBRAL COLUMN VEINS
Internal Vertebral Venous Plexus
External Vertebral Venous Plexus
Intervertebral Veins
Segmental Drainage
Intercostal veins :
Anteriorly : 2 veins in each intercostal space.
Posteriorly : 1 vein in " " "
* Anterior intercostal veins have the same arrangement and mode of drainage on both sides.
Posterior " " " " different mode " " "
Ant. intercostal veins :
Because : 1st - 6th intercostal arteries arise from internal thoracic artery.
7th - 9th " " " musculophrenic branch
Posterior intercostal veins
Anterior Abdominal Wall:
The same as the arteries:
→ Below the umbilicus: "ICE"
1. Superficial iliac circumflex v.
2. Superficial Epigastric v. ] from femoral v.
→ Upper to the umbilicus "LATTE" (axillary v.)
1. Lateral thoracic v.
2. Inf. Epigastric v.
3. Sup. Epigastric v.
* lateral thoracic v. & Sup. Epigastric v. make anastmoses Thoraco-Epigastric v.
↓ drain into IVC.
* If IVC is blocked the blood goes to the SVC.
Posterior Abdominal wall:
The veins are tributaries of the IVC, except for the left testicular or ovarian vein , wich enters the left renal vein.
