Flashcards in Anatomy of O and G incisions Deck (29)
1

What is a laparotomy

A vertical midline incision

2

What type of incision is used in a lower segment caesarean or abdominal hysterectomy

Suprapubic or Pfannenstiel incision

3

What is the linea alba

midline blending of aponeuroses

4

where do the external oblique muscles attach

Between the lower ribs and iliac crest, pubic tubercle and linea alba

5

What direction do the external oblique fibres run in

hand in pockets direction

6

Where does the internal obliques attach

Lower ribs, thoracolumnar fascia, iliac crest and linea alba

7

what direction dot he internal obliques run in

same direction as internal intercostals

8

where does transversus abdominus attach

between lower ribs, thoracolumar fascia, iliac crest and linea alba

9

what divides up each rectus abdominus

tendinous intersections

10

What is the rectus sheath

combined aponeuroses of anterolateral abdominal wall muscles

11

why is the rectus sheeth stitched up again after surgery

Increases the wound strength and reduces the risk of complications such as an incisional hernia

12

What is the nerve supply to the anterolateral abdominal wall

thoracoabdominal nerves
subcostal
iliohyogastric
ilioinguinal

13

Where do the thoracoabdominal nerves emerge from

the 7-11th intercostal nerves

14

what is the nerve root of the subcostal nerve

T12

15

What is the root of iliohypgastric

L1

16

What is the root of ilioinguinal

L1

17

Where do the named nerves travel in the abdomen

they travel in the plane between internal oblique and transversus abdominus

18

What is the blood supply to the anterior abdominal wall

Superior epigastric arteries and inferior epigastric arteries

19

Where does the superior epigastic artery continue form

the internal thoracic

20

Where does the inferior epigastric artery branch from

the external iliac

21

At what layer do both superior and inferior epigastric arteries lie in the abdomen

Posterior to rectus abdominis

22

what arteries supply the lateral abdominal wall

Intercostal and subcostal arteries (continuation of posterior intercostal arteries)

23

in what circumstance is the fasicila layer stitched closed

in increased BMI

24

Why are misline laparotomies more difficult to heal

relatively bloodless - increases chance of wound complications

25

In what areas are ports inserted for laparoscopy

subumbilical
lateral ports

26

what artery can be injured when inserting a lateral port

inferior epigastric

27

where is the deep inguinal ring situated

half way between the ASIS and the pubic tubercle

28

where does the inferior epigastric artery emerge in the abdomen

just medial to the deep inguinal ring

29

Which artery could be damaged easily in a hysterectomy

uterine artery - water under the bridge
