article description
Cervical Traumatic SSH are very rare in literature. They are usually caused by cardiopulmonary diseases that increase vascular pressure causing spinal vessels rupture. In thoracolumbar spine, the spinal puncture is the most common cause. The ventrolateral position is even more unusual. In traumatic brain injury (TBI), an abrupt extension-flexion movement could have caused the rupture of subarachnoid vessels. This, accompanied by the slowed blood "wash out" (probably due to the previous osteoarthrosis and spinal canal stenosis), led to the formation of an organized clot, which caused an acute spinal cord compression syndrome. Cervical subarachnoid spinal hematoma can present as Brown-Séquard syndrome. The treatment is prompt surgical removal and decompression. The posterior approach (partial hemilaminectomy with or without laminoplasty) with microsurgical technique is feasible, fast and simple to evacuate the hematoma with good results. Surgical nuances in posterior approach are: small spinal canal, difficulty in mobilizing the cervical cord, these haematomas are wrapped and attached to the spinal cord or nerve roots by multiple arachnoid bands, requiring techniques of Microdissection for its evacuation unlike the epidural and subdural haematomas that are easily aspirated. Here, we report a unique case of a ventrolateral SSH due to TBI.
