Anatomic borders of a inferior lumbar hernia of Petit?
Latissimus dorsi (posteriorly), iliac crest (inferiorly), posterior border of the external oblique
(anteriorly)
What are the diagnostic criteria for brain death?
1) Normothermia for > 6 hours
2) No brainstem reflexes
3) Positive apnea test (PCO2 > 60 or >20mmHg above baseline after 10 minutes off ventilator)

What is the gold standard imaging test for brain death? What is an alternative test?
Gold standard: 4-vessel angiography
Backup test: radionucleotide scintigraphy
What is the preop medication before resecting an aldosteronoma?
Spironolactone
Treatment for an acute provoked VTE with modifiable risk factors?
Anticoagulation for at least 3 months, modify risk factors
Treatment for an acute provoked PVE without modifiable risk factors?
Indefinite anticoagulation
, Treatment for an unprovoked VTE?
Indefinite anticoagulation
Branching fibrovascular core with epithelial + myoepithelial layers and cellular atypia = what is

What are the 3 mechanisms by which full-thickness grafts survive at the donor site, in order?
1) Plasmatic inbibition (passive absorption)
2) Inosculation (forming vascular connections between graft and site)

What is the most serious complication of liver transplant? What are the symptoms? What is the
treatment?
Primary graft non-function is the most serious complication.
Symptoms are continued, progressive liver dysfunction after transplantation.
Treatment is emergent re-transplantation.
