Subdural Tapping

✓ The cases of 30 infants with chronic subdural hematoma treated surgically between 1978 and 1987 (after the introduction of computerized tomography) were reviewed. This series was limited to infants presenting with increased intracranial pressure, neurological deficits, or developmental retardation. Nineteen patients were male and 11 were female, ranging in age from 1 to 14 months (average 6.1 months). The surgical treatment was initiated with percutaneous subdural tapping which was repeated periodically, if indicated, for 2 weeks. If the patients failed to respond to subdural tapping, subdural-peritoneal shunting was installed. The follow-up periods were from 3 months to 9 years 8 months (average 4 years 10 months). Computerized tomography at that time disclosed disappearance or minimal collection of subdural fluid in 28 cases (93%) and a significant collection (> 5 mm) in two (7%). Neurological examination revealed that the patients were “normal” in 17 cases (57%), “mildly or moderately disabled” in nine (30%), and “severely disabled” in four (13%). The majority of disabled patients had lesions secondary to infantile acute subdural hematoma, child abuse, or hemorrhagic diathesis. These results indicate that the treatment protocol in the present series is acceptable for the elimination of subdural hematoma. Together, early diagnosis and treatment of the etiological conditions causing the lesion are indispensable for obtaining a satisfactory neurological outcome.

✓ 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.

Subdural Tapping

✓ Twenty-six cases of infantile acute subdural hematoma treated between 1972 and 1983 were reviewed. The series was limited to infants with acute subdural hematoma apparently due to minor head trauma without loss of consciousness, and not associated with cerebral contusion. Twenty-three of the patients were boys, and three were girls, showing a clear male predominance. The patients ranged in age between 3 and 13 months, with an average age of 8.1 months, the majority of patients being between 7 and 10 months old. Most of the patients were brought to the hospital because of generalized tonic convulsion which developed soon after minor head trauma, and all patients had retinal and preretinal hemorrhage. The cases were graded into mild, intermediate, and fulminant types, mainly on the basis of the level of consciousness and motor weakness. Treatment for fulminant cases was emergency craniotomy, and that for mild cases was subdural tapping alone. For intermediate cases, craniotomy or subdural tapping was selected according to the contents of the hematoma. The follow-up results included death in two cases, mild physical retardation in one case, and epilepsy in one case. The remaining 23 patients showed normal development. The relationship between computerized tomography (CT) findings and clinical grading was analyzed. Because some mild and intermediate cases could be missed on CT, the importance of noting the characteristic clinical course and of funduscopic examination is stressed.

✓ The authors used light and electron microscope to examine the capsules of chronic subdural hematoma in 33 cases. In cases with neurological deficits, capillary endothelial cells in the capsule had many cytoplasmic protrusions and fenestrations, suggesting high permeability of the capillary wall. Endothelial degeneration was also observed in these cases. These morphological changes were reversed by osmotherapy. Formation of collagen fibrils from fibroblasts in the hematoma capsule was frequently observed in the cases treated by osmotherapy.

✓ A clear interface dividing subdural hematoma into an upper hypodense and a lower hyperdense part was seen on computerized tomography (CT) scan in seven of 140 patients with chronic subdural hematoma. All except one of the seven patients had a definite history of head trauma more than 1 month before they developed acute disturbances of consciousness and pronounced hemiparesis. Consequently, they remained bed-ridden until they underwent drainage of the subdural hematoma. This group was compared to seven chronic subdural hematoma patients with mild clinical manifestations who were selected and intentionally confined to bed for a period before CT examination and craniotomy. The CT scans in this latter group did not show the clear interface in the subdural hematoma seen in the first group. Based on this study, it is hypothesized that this sedimentation level occurred as a result of rebleeding into a chronic hematoma that was sufficiently old to result in its contents being homogenous prior to the rebleed. In cases of rebleeding, a sufficient period of bed confinement in the brow-up position before CT examination allows development of a gravitational sedimentation in the hematoma. This clear level of sedimentation is seen in only a small portion of patients, but this finding may be specific for a significant amount of rebleeding and may herald acute deterioration.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.

Diffuse Brain

✓ Dynamic computerized tomography (CT) was performed on 42 patients with acute head injury to evaluate the hemodynamics and to elucidate the nature of fatal diffuse brain bulk enlargement. Patients were divided into two groups according to the outcome: Group A included 17 nonfatally injured patients, eight with acute epidural hematomas and nine with acute subdural hematomas; Group B included 25 fatally injured patients, 16 with acute subdural hematomas and nine with bilateral brain bulk enlargement. Remarkable brain bulk enlargement could be seen in all fatally injured patients with acute subdural hematoma. In 29 (69%) of 42 patients, dynamic CT was performed within 2 hours after the impact. In the nonfatally injured patients with brain bulk enlargement, dynamic CT scans suggested a hyperemic state. On the other hand, in 17 (68%) of the 25 fatally injured patients, dynamic CT scans revealed a severely ischemic state. In the fatally injured patients with acute subdural hematoma, CT Hounsfield numbers in the enlarged hemisphere (hematoma side) were significantly lower than those of the opposite side (p < 0.001). Severe diffuse brain damage confirmed by follow-up CT scans and uncontrollable high intracranial pressure were noted in the fatally injured patients. Brain bulk enlargement following head injury originates from acute brain edema and an increase of cerebral blood volume. In cases of fatal head injury, acute brain edema is the more common cause of brain bulk enlargement and occurs more rapidly than is usually thought.

✓ The nonsurgical treatment of a case of interhemispheric subdural empyema is reported. At the time of diagnosis, the patient had a mild decrease in consciousness and only moderate focal neurological deficits. Computerized tomography (CT) confirmed the limited (interhemispheric) extent of the intracranial infection. After drainage of the nasal sinuses and antibiotic treatment, the patient recovered, although the lesion was initially increased in size on CT scanning.
