This document provides tips for using a PowerPoint presentation on the thoracic duct: 1. The presentation can be freely downloaded, edited, and modified. Many of the slides are blank except for the title to facilitate active learning. 2. The instructor should first show blank slides related to a topic and ask students what they know, then show the next slide with information. 3. This process of blank slide then information slide should be repeated for revisions and self study. 4. The presentation covers the introduction, formation, course, relations, tributaries and applied anatomy of the thoracic duct.

1. Tips on using my ppt.
1. You can freely download, edit, modify and put your
name etc.
2. Don’t be concerned about number of slides. Half the
slides are blanks except for the title.
3. First show the blank slides (eg. Aetiology ) > Ask
students what they already know about ethology of
today's topic. > Then show next slide which enumerates
aetiologies.
4. At the end rerun the show – show blank> ask questions >
show next slide.
5. This will be an ACTIVE LEARNING SESSION x
three revisions.
6. Good for self study also.
7. See notes for bibliography.

6. Introduction
- Is the largest lymphatic trunk which drains
chyle(product of fat digestion) & most lymph of body.
- Extent- Upper abdomen at lower border of T12 to
lower part of neck, crossing post & sup mediastinum
- 45cms long & 0.5cms wide
- Appears Beaded due to presence of many valves in its
lumen

7. Drains lymph from whole of body except
• Rt side of head & neck
• Rt upper limb
• Rt lung & thoracic wall
• Rt side of heart and rt surface of liver
Area of drainage

9. Course of Thoracic Duct
9

10. Course:
10

11. Course:
 Begins in abdomen at lower border of T12 as a continuation of
cisterna chyli
 Enters post mediastinum through aortic opening of diaphragm(T12)
 At T5 shifts to left & runs in superior mediastinum
 At C7 (root of neck) arches laterally, then downwards
 Ends at angle formed by union of left int jugular vein
& lt subclavian vein, (regurge of blood prevented by
a pair of valves)
11

12. Tributaries:
 Receives lymph from both halves below diaphragm
through Cisternae chyli & Lt half above diaphragm
1. From post IC lymph nodes of lower 6 spaces
2. From upper lumbar nodes(paraaortic LN)
3. From Post Mediastinal lymph nodes & post IC LNs of
upper 6 IC spaces
4. From axilla through Lt Subclavian trunk
5. From nodes in Lt ½ of H & N thru Lt Jugular trunk
6. From Lt half of thorax (Lt lung & Lt side of heart) through
Lt Bronchomediastinal trunk
12

13. Applied anatomy
 Obstruction of Thoracic duct – Due to mature
filarial parasites lymph vessels get burst
chylothorax, chyloperitoneum, chyluria.
 Cervical part of thoracic duct is damaged in
block dissection of neck
 Thoracic duct is very thin walled and colourless
so more prone for injury during surgery in post
mediastinum. 13
