Professional Statement

Dr. Darrell L. Cass has particular expertise and clinical interest in fetal surgery for a number of fetal disorders and neonatal surgery for all newborns with surgical problems, including Hirschsprung's disease and esophageal atresia. He is also experienced in laparoscopic and minimally invasive surgery, chest and lung surgery, the Nuss repair of chest wall deformities, and endocrine surgery.

Dr. Cass’s basic research interests center on the mechanisms of fetal tissue healing. He has shown that fetal skin and fetal arteries have remarkable healing capabilities characterized by rapid healing, minimal inflammation, and smaller scars. Dr. Cass’s research goal is to understand the mechanisms involved in these unique reparative processes in order to develop new strategies to surgically treat problems that affect the developing fetus. Another goal of Dr. Cass’s fetal tissue healing research is to develop new treatments to minimize or prevent scarring in children and adults. Dr. Cass’s clinical research focuses on treatment advances of fetal and neonatal surgical conditions.
