Pediatric Abdominal Organ Transplantation: Current Indications, Techniques, and Imaging Findings

Abstract

The anatomy, normal postoperative radiological appearance, and imaging features of common postoperative complications of pediatric abdominal transplants are reviewed, including renal, liver, and intestinal transplants. Doppler ultrasound is the mainstay of imaging after transplantation. Computed tomography (CT) and CT angiography, MR imaging and magnetic resonance (MR) angiography, MR cholangiopancreatography, conventional angiography, and nuclear medicine imaging may be used for problem-solving in pediatric transplant patients. Accurate and timely radiological diagnosis of transplant complications facilitates appropriate treatment and minimizes morbidity and mortality.
