title: [Congestive myelopathy caused by spinal dural arteriovenous fistulas. Anamnesis, clinical aspects, diagnosis, therapy and prognosis].
abstract: Congestive myelopathy, formerly referred to as varicosis spinalis or Foix-Alajouanine syndrome, is caused by a spinal dural arteriovenous fistula (SDAVF). So far, the blood supply from the meningeal arteries draining through the fistula into the medullary venous system can only be verified by spinal angiography. Patients predominantly male and over the age of 60 are afflicted. Initially reversible functional disorders caused by the congestion of the spinal cord veins eventually become irreversible, the most common symptom being an increasingly paretic gait disorder, the signs of which generally begin symmetrically and progress from distal to proximal signs. Simultaneously, predominantly transverse sensory dysfunctions develop, as well as bladder and bowel dysfunctions, most often leading to incontinence. MRI typically shows a central medullary signal enhancement with slight swelling of the afflicted region, initially indicative of a reversible congestive edema and later of an irreversible infarction, and extended perimedullar vessels. Thus, if the clinical course and the characteristic MRI findings suggest the possibility of disease related to congestive myelopathy, spinal angiography becomes indispensable. Since ensuing the success of therapy and prognosis depends on rapid determination of the extent of the illness, a speedy diagnostic reaction is mandatory to institute the treatment necessary to prevent paraplegia.
