✓ The etiopathogenesis of traumatic spinal subdural hematoma (SSH) is uncertain. Unlike the supratentorial subdural space, no bridging veins traverse the spinal subdural space. The authors describe a case of subacute SSH that occurred after spontaneous resolution of traumatic intracranial SDH and suggest a causal relationship between the two. A 23-year-old woman suffered an acute intracranial SDH after a snowboarding accident. There was no clinical or radiological evidence of spine injury. Conservative management of the supratentorial SDH resulted in spontaneous radiologically documented resolution with redistribution of blood in the subdural space. Four days after the injury, the patient started noticing new onset of mild low-back pain. The pain progressively worsened. Magnetic resonance imaging of the lumbosacral spine 10 days after the original injury revealed a large L4—S2 SDH. Ten days after the original injury, bilateral L5—S1 laminotomy and drainage of the subacute spinal SDH were performed. The patient experienced immediate pain relief. The authors hypothesize that in some cases spinal SDH may be related to redistribution of blood from the supratentorial subdural space.

✓ A method for producing a clinical form of experimental chronic subdural hematoma is reported. When blood is mixed with cerebrospinal fluid and incubated, a peculiar clot is formed which, when inoculated into the subdural space of dogs or monkeys, grows gradually. Histologically the capsule of the hematoma is comparable to that seen in human chronic subdural hematoma. In some animals progressive hemiparesis develops.

Object. This study was conducted to determine the best position for the subdural drainage catheter to achieve a low recurrence rate after burr-hole irrigation and closed-system drainage of chronic subdural hematoma (CSDH).Methods. The authors studied 63 patients with CSDH in whom the drainage catheter tip was randomly placed and precisely determined on postoperative computerized tomography (CT) scans and 104 patients with CSDH in whom CT scans were obtained 7 days postsurgery. The location of the subdural drainage catheter, the maximum postoperative width of the subdural space, and the percentage of the ipsilateral subdural space occupied by air postoperatively were determined and compared with the postoperative recurrence and reoperation rates.Patients with parietal or occipital drainage had a higher rate of CSDH recurrence and much more subdural air than those with frontal drainage. In addition, patients with residual subdural air demonstrated on CT scans obtained 7 days postsurgery also had a higher recurrence rate than those without subdural air collections. Furthermore, patients with a subdural space wider than 10 mm on CT scans obtained 7 days postsurgery had a higher recurrence rate than those with a space measuring 10 mm or less.Conclusions. The incidence of postoperative fluid reaccumulation seems to be reduced by placing the tip of the drainage catheter in the frontal convexity and by removing subdural air during or after surgery.

✓ A case of interhemispheric subdural hematoma (ISH) is presented and discussed. This disorder is a rare form of intracranial hemorrhage, which classically presents as an isolated paresis of one leg or a hemiparesis worse in the leg than the arm. The majority of cases are due to occipital trauma because of the anatomy of the bridging veins. Chronic interhemispheric hematomas are rare since the natural history of these lesions is to spread out over the cerebral convexity. Conservative treatment for ISH may be beneficial unless neurological deterioration necessitates early operative intervention.

✓ The authors describe studies performed on material aspirated from chronic subdural hematomas. Patients were given 51Cr-labeled red cells prior to aspiration, and it was possible to demonstrate that the mean daily hemorrhage into the hematoma space amounted to 10.2% of its volume. Immunoelectrophoresis of the aspirated hematoma fluid by monospecific anti-human fibrinogen revealed the presence of fibrin and fibrinogen degradation products that, measured by hemagglutination-inhibition immunoassay techniques, varied between 5.0 and 10,500 µg/ml with an average of 2604 µg/ml in 18 cases. The tissue activator was demonstrated by Todd's histological localization in the outer membrane of the chronic subdural hematoma in 11 cases, but not in the inner membrane. These results indicate that if a clot in the subdural space causes the formation of neomembrane, and excessive fibrinolysis occurs, the subdural clot would not only liquefy, but also enlarge by continuous hemorrhage from the neomembrane. Therefore, local hyperfibrinolysis and continuous bleeding are important in the etiology of the chronic subdural hematoma.

✓ The authors review 29 cases of surgically-proven isodense subdural hematomas examined by non-contrast and contrast-enhanced computerized tomography scans. Three types of isodense collections were noted: homogeneous isodense collections, mixed-density collections, and gravitational layering within subdural collections. Contrast enhancement within the cerebral cortex, cortical vessels, and subdural membranes led to the correct diagnosis in each case. Contrast-enhanced scans are essential for the evaluation of isodense subdural hematomas.

✓ Two cases of internal carotid artery occlusion secondary to spontaneous dissection are reported. Both patients presented with transient ischemic attacks. Both had antiplatelet aggregation therapy, followed by spontaneous resolution of the occlusion. The period of healing seems to be relatively short. In both cases, restoration of flow was angiographically documented 14 days and 10 weeks after the initial arteriogram. Strategies for treatment of such patients are discussed.

✓ In a consecutive series of 39 cases of acute subdural hematoma (SDH), encountered since computerized tomography diagnosis became available, 61.5% were found to be the result of bleeding from a small cortical artery, 25.6% were of venous origin, 7.7% resulted from cerebral contusions, and 5% were acute bleeds into chronic subdural hematomas. Craniotomy was performed promptly on admission, but there was no difference in survival (overall 51.3%) between patients with arterial and venous bleeds. The only apparent factor affecting survival in this series was the preoperative neurological status: 67% of patients who were decerebrate and had fixed pupils prior to operation died. Of patients with less severe neurological dysfunction, only 20% failed to survive.
