86 peritoneum, retroperitoneum Flashcards
Structures in the inguinal canal
Vaginal process,
Spermatic cord/round ligament
external pundendal vessels
genital nerve
Structures in the femoral ring/vascular lacunae
Femoral a+v
lymphatics
saphenous nerve
How does the cullen sign arise
direct communication between abdominal cavity and s/c around umbilicus
Three openings in diaphragm and which structures in each
Caval foramen - caudal vena cava
Oesophageal hiatus - oesophagus, vagus, oesophageal vessels
Aortic hiatus - aorta, azygos, hemiazygos, thoracic duct
Where do sympathetic chain and splanchnic vessels travel across diaphragm
paired slit openings in dorsal diaphragm. clinical significant in some conditions affecting both cavities
what are the 3 portions of the greater omentum
Bursal - greater curvature of this stomach, extends caudally to bladder covering the intestines. folded so superficial and dorsal layer. potential space between two = omental bursa.
Splenic - extends to hilus of spleen to form gastrosplenic ligament
Veil - left limb pancreas
where is the lesser omentum and what does it give rise to
between lesser curvature of the stomach and portages hepatis. Gives rise to hepatoduodenal lig and hepatogastric ligament.
what forms the epiploic foramen
dorsally = cava ventral = portal vein
When are organs considered retroperitoneal?
When covered on one aspect only with peritoneum.
Adrenal, kidneys, ureters, Aorta, lumbar lymph nodes, caudal cava
Normal range of intraabdominal pressure in dogs
2-7.5cm H20
At what intraabdominal pressure should surgical decompression be considered
> 30cmH20
What has been shown to correct low mucosal perfusion caused by moderately increased abdominal perfusion
low dose infusion dobutamine
What, apart from inflammatory cells and fibrin, is required for adhesion formation?
tissue ischaemia/vascular damage
fibroblasts infiltrate
which interleukin is anti inflammatory
IL-10
