secondary liver failure
No pre-existing liver disease. The Liver failure is a result of the patient’s overall critical condition.
Lung major fissure separates…
lower lung from middle/upper lung. (also called oblique fissure)
Treatment for malignant hyperthermia?
Stop offending anesthetic, Stop surgery, 100% O2, give dantrolene 2.5mg/kg q5min, glucose, HCO3, alternate anesthetic
Longest and most variable phase of cell cycle
G1.
Not G0, division stops in G0.
Most radiosensitive phase of the cell cycle
G2 and M
Most radioRESISTANT phase of the cell cycle
S phase
p53 mutations arrest in what phase of cell cycle
G1.
Associations with GB cancer
Cholelithiasis (especially > 3cm), limited areas of calcification but not diffuse calcification/porcelain, polyps > 1cm (esp solitary), choledochal cysts
Boundaries of the femoral canal
iliopubic tract superiorly,
Cooper ligament inferiorly,
femoral vein laterally,
lacunar ligament medially (junction of the iliopubic tract and Cooper ligament)
Hepatic adenoma appearance on imaging?
Tx?
Strong early-phase enhancement, hyperintense on T1 and rapid washout. NO Kupffer cells.
Tx: If < 4cm and asymptomatic then stop OCPs, observe. If persists then resect, malignant potential.
If > 4cm then resect, malignant potential + risk of rupture, 30-50%?
FNH appearance on imaging?
Tx?
Nearly isointense on T1 & T2.
Homogeneous mass with maybe central scar that enhances rapidly during arterial phase.
Has Kupffer cells so + on sulfur colloid scan.
Tx: No resection, may stop OCPs as well.
Liver hemangioma appearance on imaging?
Tx?
+on Tagged RBC scan (best test)
Peripheral nodular enhancement on CT/MRI/
Tx: Asymptomatic = conservative.
Symptomatic then resect +/- pre-op embolize.
Unresectable? Then steroids or possible XRT.
Solitary wall of blue hue on liver during OR?
Solitary liver cyst. Most are left alone.
What is may-thurner syndrome?
Left common iliac vein obstruction as is crosses under the right common iliac artery.
> in women.
May need thrombolysis, angioplasty, stenting
Difference between chronic and acute liver failure?
Acute liver failure patient will be unstable and coagulopathic.
