When Type 1 von Willebrand Disease Lives Together with Hashimoto Thyroiditis, Hypothyroidism, Hypoparathyroidism, Morbid Obesity, and Bariatric Surgery: A Case Report

Von Willebrand disease (vWD) is the most common bleeding disorder with type 1 being the more prevalent, although underdiagnosis is an actual concern. This case is the first clinical report of a type 1 vWD with several comorbidities submitted to bariatric surgery. The authors demonstrate the importance of a diagnosis and the consideration of other diseases or disturbances in vWD patients’ perioperative management. A multidisciplinary approach is crucial for minimizing and preventing bleeding risk.
