Transösophageale Echoskopie des Spinalkanals^*

Abstract

Transoesophageal ultrasound imaging of the spinal canal through an intervertebral disc was successfully achieved in 44 of 50 adults (18 women and 32 men; mean age 56 years, range 22-79) who, for cardiological indications had transoesophageal echocardiography. On average, five (range 1-11), usually sequential, segments were visualized. In 37 patients pulse-synchronous sagittal displacement of the spinal cord was noted, presumably caused by cerebrospinal fluid pulsation. In one woman, with known syringomyelia, the spinal cord cavity was well shown. Real-time demonstration of dynamic events in the spinal canal opens up new possibilities for the diagnosis and follow-up monitoring of spinal diseases.
