Williams Syndrome And Anesthesia

Williams syndrome affects approximately one in 10 000 people and is caused by the deletion of genes on chromosome 7q1123 which code for elastin. In general anesthesia is deemed safe for individuals with WS. The risk of sudden death in this population is 25 to 100 times that of the general population with many documented deaths associated with sedation or anesthesia. Although a relatively rare disease these patients frequently require sedation or anesthesia for a variety of medical procedures. Patients with Williams syndrome are considered at high risk for anesthesia-related adverse events. Patients with Williams syndrome have increased morbidity and mortality under sedation and anesthesia largely as a result of cardiovascular abnormalities. Since the first description in 1961 several case reports have documented an increased incidence of anesthesia-related cardiac arrest in patients with WilliamsBeuren syndrome commonly known as Williams syndrome WS.
