CCTC Immediate Postoperative Care 3

Question 1

Which laboratory value is the most sensitive early marker for hepatic artery thrombosis after liver transplant?

Accepted Answer

Liver transaminases (AST/ALT)

Answer

Transaminases (AST/ALT) rise rapidly and dramatically with hepatic artery thrombosis due to acute hepatocellular ischemia.

Question 2

A renal transplant patient in the immediate postoperative period develops oliguria with a rising creatinine. Doppler ultrasound shows normal arterial and venous flow. What is the most likely cause?

Accepted Answer

Delayed graft function (DGF)

Answer

Delayed graft function is the most common cause of oliguria with normal blood flow after kidney transplant, typically resulting from ischemia-reperfusion injury.

Question 3

What is the primary purpose of maintaining a strict fluid balance record in the immediate post-transplant period?

Accepted Answer

To guide fluid resuscitation and detect third-spacing or hemorrhage

Answer

Precise fluid balance monitoring guides resuscitation and helps detect hemorrhage, third-spacing, or inadequate organ perfusion early.

Question 4

Which post-transplant complication is best detected by Doppler ultrasound in the immediate postoperative period?

Accepted Answer

Vascular thrombosis of graft vessels

Answer

Doppler ultrasound is the first-line imaging study to evaluate vascular complications such as arterial or venous thrombosis in the transplanted organ.

Question 5

A post-liver transplant patient develops confusion and asterixis on postoperative day 2 despite a functioning graft. What metabolic complication should be suspected?

Accepted Answer

Hyperammonemia

Answer

Residual hyperammonemia from the pretransplant liver disease can persist postoperatively and cause encephalopathy even with a functioning graft.
