Anatomy of Surgical Incisions Flashcards
What is the term for the abdominal wall’s midline blending of aponeurosis?
linea alba
What improve mechanical efficiency of the rectus abdominal muscles?
tendinous intersections, dividing each muscle into 3 or 4
What is immediately deep to the superficial fascia?
rectus sheath
Nerve supply to anterolateral abdominal wall?
enters from lateral direction
7-11th intercostal nerves become thoracoabdomonal
T12, L1
Blood supply to anterior abdominal wall?
superior and inferior epigastric arteries
Blood supply to lateral abdominal wall?
intercostal and subcostal arteries (which are continuations of posterior intercostal arteries)
In what direction should incision to muscle be made?
in same direction as muscle fibre
Are rectus muscles cut in an LSCS incision?
no, separated in lateral direction
What layers need to be stitched closed in an LSCS incision?
uterine wall
rectus sheath skin
Which layers need to be stitched closed in a laparotomy?
peritoneum and linea alba
fascia
skin
Is healing good in a midline incision?
no - relatively bloodless, increasing chance of wound complications eg dehiscence and incisional hernia
If a lateral port is required in a laparoscopy, care must be taken to avoid which artery?
inferior epigastric
What is the inferior epigastric artery a branch of?
external iliac
Which artery emerges just medial to the deep inguinal ring?
inferior epigastric
During hysterectomy, extreme care must be taken to differentiate the ureter from the what?
