Surgical Incisions Flashcards
Give some common surgical incisions done in O&G
Lower segment C-section
Laparotomy
Hysterectomy
Laparoscopy
Which three muscles form the layers of the anterolateral abdominal wall?
External oblique
Internal oblique
Transversus abdominis
Which abdominal wall muscle is found in the midline?
Rectus abdominis
Which abdominal wall muscle fibres has a ‘hands in pocket’ orientation?
External oblique
The external oblique muscles run from which ribs (roughly)?
Rib 5 to 11
What are the distal attachments of the external oblique muscles?
Iliac crest
Linea alba
What is the orientation of the internal oblique muscle fibres?
Hands on chest
Which ribs do the internal obliques attach to?
Lower ribs (10/11/12)
What divides the rectus abdominis into sections?
Tendinous intersections
What forms the linea alba?
Interweaving of muscle aponeuroses
What forms the rectus sheath?
Combined aponeuroses of anterolateral abdominal wall muscles
The rectus sheath is anterior/posterior to the rectus abdominis below the arcuate line
Anterior
Which nerves supply the anterolateral abdominal wall?
Thoracoabdominal
Subcostal
Iliohypogastric
Ilioinguinal
The nerves to the abdominal wall run within which muscles?
Internal oblique and transversus abdominis
What is the main blood supply to the anterior abdominal wall?
Inferior epigastric arteries
The inferior epigastric arteries are branches of which structure?
External iliac artery
The inferior epigastric arteries lie deep to what structure?
Rectus abdominis
In a LSCS the rectus abdominis muscles are/are not cut
Are not cut
Why are laparatomy scars poor at healing?
As they are relatively bloodless
What incision is usually done in laparoscopy?
Sub-umbilical
What artery must be considered if using a lateral port for laparoscopy?
Inferior epigastric artery
Which artery must be considered when performing a hysterectomy?
Uterine artery
