In this episode of "PICU Doc on Call," Drs. Pradip Kamat and Rahul Damania dive into a pediatric ICU case involving a 4-year-old girl who presents with severe anemia and bleeding, ultimately diagnosed with von Willebrand disease (VWD). They chat about the causes and different types of VWD, walk through the key clinical features, and break down how to diagnose and manage this condition. Drs. Kamat and Damania highlight the important roles of desmopressin and factor concentrates in treatment. Throughout the episode, they stress the need to recognize VWD in kids who have mucosal bleeding and offer practical tips for intensivists on lab evaluation and treatment strategies for this common inherited bleeding disorder.
