Abdominal Wall Reconstruction Flashcards
Hernia mesh reduces hernia recurrence by about 50%.
T
lightweight meshes
and macroporous meshes have lost favor because of their adverse effects
F lightweight meshes
and microporous meshes have lost favor because of their adverse effects
as small bites 5 mm apart,
5 mm from the fascia edge to close laparotomy wounds
T
In Diastasis recti there is fascia! defect
F Diastasis recti is a widening of the linea alba fascia with lateralization of the rectus abdominis muscles but no fascia! defect
paper in the Lancet, support the use of
hernia mesh prophylactically in high risk undergoing laparotomy to
prevent hernia occurrence
T
Incarcerated hernia,
hernia with compromised blood
supply
F Nonreducible hernia that may cause pain and
bowel obstruction
Amyand hernia mean Hernia that contains the appendix
T
Richter hernia
Hernia defect that contains only the antimesenteric
border of bowel
the linea alba is central fascia between
the paired recti and the semilunar line is the lateral border of the
recti
T
The recti originate from the symphysis pubis and the pubic crest
and insert onto the seventh costal cartilages and the
xiphoid process
F The recti originate from the symphysis pubis and the pubic crest
and insert onto the fifth, sixth, and seventh costal cartilages and the
xiphoid process
What is the The arcuate line ?
a horizontal line below the umbilicus
that demarcates the lower limit ofthe posterior rectus sheath, and it is
also where the inferior epigastric vessels perforate the rectus abdominis.
The posterior rectus sheath is composed of two overlapping fascia layers that are continuations of the external oblique aponeurosis
and internal oblique aponeurosis, respectively.
F The anterior rectus sheath is composed of two overlapping fascia layers
The posterior rectus sheath composed of two overlapping fascia layers that are continuations of the internal oblique aponeurosis and the
transversalis fascia
T
The muscular/fascia! layers lateral to the semilunar line
the external oblique aponeurosis, external oblique musculature.
internal oblique aponeurosis internal oblique musculature,
transversalis fascia, and transversus abdominis
parietal peritoneum
If nerves are injured, bulges will occur and bulges are
difficult to manage because adynamic fabric or scar underperforms
innervated muscle
T
The rectus muscle is innervated by the lower
intercostal and lumbar neurovascular bundles
T
neurovascular bundles traveling between the
external oblique and internal oblique muscles and is a target
for regional nerve blocks
F neurovascular bundles traveling between the
internal oblique and transversus abdominis muscles and is a target
for regional nerve blocks
The superior artery runs the length of the rectus muscle and joins the
deep inferior epigastric artery that originates from the external iliac
artery superior to the inguinal ligament
T
shingles may
weaken the abdominal wall musculature
T
small tissue bites of5 mm every 5 mm with 2-0 absorbable suture
lead to fewer hernias (13%) versus large tissue bites of I cm every
I cm (21%)
T
lightweight meshes have
been associated with ventral hernia recurrence because of mesh tearing
T
Degradable meshes are significantly
more expensive than nondegradable meshes but purportedly safer for
use in clean wound only
F Degradable meshes are significantly more expensive than nondegradable meshes but purportedly safer for
use in clean-contaminated and contaminated cases
that more than three fixation points along a 7-cm region does not increase bursting strength
