Abdomen Sonography: Perfusion and Function of Transplanted Organs - Video Lesson

Hello everyone and welcome back to our abdominal ultrasound series! Today's lesson will cover the important vascular flow and Doppler patterns that are found after successful liver and or kidney transplant surgeries. We'll compare normal versus abnormal perfusion patterns that can easily be seen on Doppler imaging. Let's get started! Let's start with an important term. You'll often hear the word graft in transplant imaging. The graft is just another way of referring to the transplanted organ, whether it's a liver or a kidney. When we describe graft function, we're describing how well that transplanted organ is working inside the patient. For the liver transplant, a normally functioning graft will appear homogeneous with smooth margins and without focal lesions. The biliary tree should not be dilated and there should not be significant ascites or fluid collections around the liver. In a liver transplant, the donor liver is surgically connected to the recipient through several key
