SINE
Also written as: SINE — Spinal Ischemic Neurologic Event
Acronym for Spinal Ischemic Neurologic Event, a complication of thoracoabdominal aortic surgery affecting spinal cord function.
Full Definition
SINE (Spinal Ischemic Neurologic Event) encompasses a spectrum of neurological complications affecting the spinal cord following thoracoabdominal aortic surgery or endovascular procedures. These events range from temporary weakness to permanent paraplegia and result from interruption of blood supply to the spinal cord through sacrifice or occlusion of intercostal and lumbar arteries. The incidence varies with the extent of aortic coverage and patient-specific factors. Prevention strategies include cerebrospinal fluid drainage, maintenance of adequate perfusion pressure, and staged procedures when possible. Recognition and prompt reporting of SINE is crucial for patient care and medicolegal documentation.
Usage
