A review is given on the current diagnosis and treatment of spinal vascular malformations with special emphasis on the use of selective spinal angiography. Spinal vascular malformations are mostly encountered within the thoraco-lumbar segment of the spinal cord. Typical clinical symptoms are due to either progressive myelopathy or hemorrhage (subarachnoidal hemorrhage). The prognosis of untreated spinal angiomas is poor. Therefore, therapeutic measures are aiming to prevent bleeding of angiomas resulting in subarachnoidal hemorrhages or hematomyelia or to prevent spinal cord ischemia due to compression. Using selective spinal angiography, spinal angiomas can now be treated successfully by complete surgical extirpation or embolization procedures. The evaluation of radicular myelopathies and subarachnoidal hemorrhages of unknown origin has also considerably benefited from this technique. It is concluded that early diagnosis of spinal vascular malformations is of crucial importance for good therapeutical results.

A twenty year old man presented an acute hematomyelia at T2-T3 level and had electrocardiographic changes suggesting subendocardial and subepicardial ischemia; he also had precordial pain and elevation of the MB fraction of creatine phosphokinase. Neurons providing heart inervation are located at the T2-T3 spinal level. The electrocardiographic changes observed were considered neurogenic in origin and were transient. Although there are experimental reports showing electrocardiographic changes associated with compression of the upper part of thoracic spinal cord, this is the first report to our knowledge, in which an acute spinal injury is shown to be associated with neurogenic changes in ventricular repolarization simulating acute myocardial ischemia.

We reviewed 44 cases of ischemia and infarction of the spinal cord at two university hospitals. Three patients experienced transient ischemic attacks. Etiologies of completed strokes were diverse and included rupture and surgical repair of aortic aneurysms, aortic dissection, aortic rupture and thrombosis, global ischemia, anterior spinal artery embolism, repair and thrombosis of spinal arteriovenous malformations, hematomyelia, epidural hematoma, cervical osteophytosis, celiac plexus block, systemic lupus erythematosus, coagulopathy, and decompression sickness. Motor function improved in 12 patients, was substantial in only one, and occurred largely within the first 2 to 4 weeks. Favorable ambulatory outcome correlated with improving neurologic examinations and relatively preserved strength in hip abductors and knee extensors. More extensive deficits without initial improvement portended a more severe prognosis. Autonomic dysfunction, pain, paresthesia, and depression were common and impeded recovery in some patients. The mean level of deficit was at T-8 and in cases of global ischemia was at T-9, which leads us to dispute the classical view of a midthoracic watershed zone of ischemic vulnerability near T-4.

The syndrome of acute central cervical spinal-cord damage, as originally described by Bailey and subsequently by Schneider, Cherry, and Pantek, consists of disproportionately greater weakness in the upper extremities as compared with the lower, with various sensory changes at or below the site of the lesion, and urinary bladder dysfunction. Three patients with this problem are presented. The mechanism of injury is discussed and related to pre-existing conditions such as cervical spondylosis as well as acute pathological entities causing central cord damage, such as hematomyelia, contusion, cord swelling, and ischemia. The treatment and prognosis of patients with this type of spinal-cord injury is outlined.
