Radiographic and Ultrasonographic Study of the Etiology of High-Rise Syndrome in Cats: A Retrospective Analysis

High-rise syndrome (HRS) is a common traumatic presentation in cats.

This study evaluated the etiology, frequency and types of radiographic and sonographic lesions associated with HRS in 120 cats.

Information regarding the circumstances of the falls was collected from the owners. The data were analysed to identify causative factors, types and frequency of injuries.

It was found that most affected patients were under 1 year old and the majority of cases fell from the third floor. Approximately 75% of cats had a history of high-risk behaviours, as reported by the owners. Femoral fractures were the most frequent skeletal injury (17.5%), while thoracolumbar spinal injuries (T13-L1) were observed in 50% of cases of vertebral column injuries. Pulmonary contusions and haemorrhage were the most common soft tissue injuries, occurring in 45% of cases. No significant correlation was found between fall height and injury severity; however, higher injury severity was associated with increased mortality. The overall survival rate was 92.5%.

Preventive measures, such as restricting access to windows and balconies, are recommended to reduce the incidence of HRS.
