Anatomy of surgical incision Flashcards
Common surgical incicision in obs and gynae?
Lower segment C Section
Laparotomy
Abdominal (and vaginal) hysterectomy
Laparoscopy
Layers of anterolateral body wall superficial to deep?
Skin Superficial fascia Ext oblique Int oblique Transversus abdominis
Attachments of external obliques?
Lower ribs
Iliac crest
Pubic tubercle
Linea alba
Attachments of internal obliques/
Lower ribs
Thoracolumbar fascia
Iliac crest
linea alba
Attachments of transversus abdominis?
Lower ribs
Thoracolumbar fascia
Iliac crest
Linea alba
What divides the rectus abdominis into smaller muscles?
Tendinous intersections
What is a rectus sheath
Anterior and posterior
Combined aponeuroses of anterolateral abdo wall muscles.
Where do the nerves that supply the anterolateral abdo wall travel?
In plane between internal oblique and transversus abdominis
Nerve supply to anterolateral abdo wall?
7-11 intercostal nerves becoming thoracoabdominal nerves
Subcostal T12
Iliohypogastric L1
Ilioinguinal L1
Blood supply to anterolateral abdo wall?
Superior and inferior epigastric arteries
Intercostal and subcostal arteries
What happens to rectus muscles in an LSCS incision?
The muscles are not cut, they are separated from each other in a lateral direction.
Advantage and disadvantages of midline incision?
+ Relatively bloodless
- Healing not as good
If a lateral port is required in laparotomy, which strucutre is it important to avoid
Inferior epigastric artery
Different types of hysterectomy?
Vaginal and abdominal
How can the uterine artery and the ureter be differentiated between during hysterectomy?
Ureter passes inferior to artery (Water under the bridge)
Ureter vermiculates when touched
