Clinical (prearteriographic) and arteriographic diagnoses were grouped into six categories each for analysis of central nervous system and systemic complications of 5,000 catheter cerebral arteriograms. Within each category, there was no significant difference in complication rate between clinical and arteriographic diagnoses. The highest complication rates (1.2%-1.9%) were in patients with cerebrovascular occlusive disease, posttraumatic or postoperative conditions, and subarachnoid hemorrhage. Significantly lower complication rates (0.2%-0.5%) were found in patients with tumor, seizure or headache, and patients with normal arteriographic findings.

A case is reported of a former woman astronaut candidate who withstood the rigors of the preliminary physical examinations for this position. Some years later, she sustained a subarachnoid hemorrhage from an arteriovenous malformation in the right parieto-occipital area, which was successfully excised. Postoperatively, she had a marked visual deficit, from which she completely recovered within 3 months. The development of psychomotor seizures 5 months later was due to probable scarring in the right parieto-occipital region of the cerebral cortex, the interpretive area for orientation of body image in space, which had been supplied by the clipped right anterior and posterior cerebral arteries feeding the arteriovenous anomaly. These seizures have been well controlled on anticonvulsants. A lesion in the temporoparieto-occipital region due to a hemorrhage from a ruptured arteriovenous anomaly, resulting in the disabling symptoms of disorientation or loss of body image due to impairment of the interpretive cortex, could be devastating to the pilot and a mission. This case raises the question of an automatic use of the CT brain scan in screening potential space candidates, and even the consideration of a percutaneous femoral four-vessel arteriogram in all, or possibly selected, candidates. Most neurosurgeons and neuroradiologists probably would consider the risks of the latter procedure too great to justify its use for fear of permanent complications to the space candidate.

The author has operated on 40 patients with giant intracranial aneurysms, using various surgical approaches. Giant aneurysms predominated in females (3:1) and were most common in the age group 30 to 60 years. Patients presented with subarachnoid hemorrhage (17), visual disturbance (18), chronic headache (14), transient or progressive hemispheric deficit (6), seizure (2), dementia (2), and cerebrospinal fluid rhinorrhea (1). Giant aneurysms were located at the carotid artery (25), the basovertebral artery (8), the anterior communicating artery (5), and the middle cerebral artery (2). Eight of 40 patients had one or more other aneurysms and/or associated arteriovenous malformations. Aneurysms were treated with intramural thrombosis (21), neck occlusion (7), trapping (10), proximal parent artery ligation (1), and aneurysmorrhaphy (1). After as much as 8 years of follow-up, 32 patients (80%) showed complete or marked improvement in signs and symptoms; two patients (5%) had a poor recovery. There were six surgical mortalities (15%). Giant aneurysms can be treated with respectable results if the surgeon selects the technique best suited to the particular aneurysm. In general, neck occlusion, trapping, and aneurysmorrhaphy are best for giant aneurysms of the anterior circulation, and intramural thrombosis is best for those of the posterior circulation. Extra- and intracranial vascular anastomotic techniques are also of value. For success, a flexible approach is essential.

Post-shunt subdural hematoma was found in two patients with hydrocephalus due to subarachnoid hemorrhage. The first case was a 46-year-old man with two episodes of subarachnoid hemorrhage from anterior communicating aneurysm. Two weeks after neck-clipping for the aneurysm, a ventriculo-peritoneal shunt with Pudenz's system was performed since hydrocephalus with moderately increased pressure had been found. He did well for one month, then soon after mild head injury, disorientation and right hemiparesis developed. Cerebral angiogram revealed avascular space in the left parietotemporal region. After the ligation of the shunt tube, subdural hematoma was removed. The symptoms improved in two weeks. The second case was a 62-year-old man with an aneurysm at the trifurcation of the right middle cerebral artery. One month after successful clipping of the aneurysm, he received a ventriculoperitoneal shunt with Pudenz's system for normal pressur hydrocephalus. One and a half years after the operations he hit his head against the ground during his convulsive seizure. Since then, disorientation, urinary incontinence and gait disturbance appeared. After cerebral angiogram, the subdural hematoma was removed and the shunt tube was ligated. He became free of these symptoms in two weeks. The cerebrospinal fluid shunt is recommended for hydrocephalus induced by subarachnoid hemorrhage, but careful follow-up is necessary since these patients might develop post-shunt subdural hematoma, especially after head trauma as shown in our cases.

Strokes in children and adolescents, although rare, are serious when they occur. A practical clinical approach is to differentiate between those events that occur in the presence of systemic disease and those that are restricted conditions involving just the intracranial circulation. Division on the basis of the presence or absence of intracranial hemorrhage further narrows down the differential diagnosis and dictates the urgency with which angiography should be performed. Treatment depends on the underlying condition and on the development of seizures, increased intracranial pressure, or subarachnoid hemorrhage. Prognostic statements are difficult and must be highly individualized.

During the 13-year period 1964 through 1976, 37 patients less than 20 years with an intracranial, parenchymal arteriovenous fistula were seen at the Mayo Clinic. The most frequent mode of presentation was hemorrhage or seizure. Other than angiography, computed tomography with contrast enhancement was the most helpful diagnostic test. Surgery was restricted to patients with intraparenchymal hematomas, intractable seizures, or subarachnoid hemorrhage with accessible lesions and to 1 infant with a massive, sumptomatic malformation. Surgery generally was tolerated well, with reversal of most acute focal neurological deficits related to hematomas. In the nonsurgical group, follow-up revealed a fairly stable neurological status during the period of the study.

A 6-year-old boy with seizures and signs of meningeal irritation was found to have a spontaneous subarachnoid hemorrhage. Investigations, including a renal biopsy, were diagnostic of an underlying acute poststreptococcal glomerulonephritis. The patient recovered and is asymptomatic three years later. This case shows that spontaneous subarachnoid hemorrhage can occur in children with acute poststreptococcal glomerulonephritis and should be suspected when meningeal manifestations are prominent.

The authors present six cases of subarachnoid hemorrhage secondary to rupture of an aneurysm of the pericallosal artery. Four of these were of the berry type and were located at the genu of the corpus callosum; in two instances the aneurysm was found at the bifurcation of an azygous or a bihemispheric pericallosal artery respectively. A fifth lesion was of the fusiform type and the sixth one represented most probably a false aneurysm. All patients have been operated upon, but in three only clipping of the neck was feasable. In the remainder one pericallosal or the azygos artery was occluded intentionally. Postoperatively, severe mental perturbation, incontinence and seizures were encountered, but all symptoms cleared during the follow-up period, and subarachnoid hemorrhage never recurred.

Twenty critically ill infants with abnormal head growth and/or seizures underwent CAT of the brain. Signs of birth asphyxia or respiratory distress were present in all. Six out of ten infants with abnormal size of the head had abnormal CAT scans. Nine out of ten infants with seizures had abnormal scans. Abnormalities included hydrocephalus, intraventricular hemorrhage, cerebral edema, subarachnoid hemorrhage and porencephaly. Six infants required neurosurgical procedures. Development at two to 15 months of age in the 19 surviving infants was normal in nine, suspect in eight, and severely delayed in two patients. Until the prognosis of the various CNS disorders discussed is clearly defined, aggressive management appears indicated.
