Transplants Flashcards
Scoring system for assessing the severity of chronic liver disease
MELD(Model for End-Stage Liver Disease)
The most common cause for liver transplants in US
- Chronic Hep C
2. Alcohol
A low RI in a liver transplant can indicate a ________
Proximal stenosis
A high RI in a liver transplant can indicate:
- rejection
- hepatic venous congestion
The most common cause for liver transplant failure is
Rejection
Liver—
- Low RI (less than 0.5)
- velocity >200 cm/s
- tardus parvus waveform
These indicate:
Hepatic artery stenosis
The most common vascular complication of liver transplantation is
HA thrombosis

Lung
Portal venous gas is (common/uncommon) during the early postoperative period.
Common
