✓ In a case of subarachnoid hemorrhage, the arteries of the circle of Willis were left undisturbed and undissected at postmortem examination. A block of frontal lobe tissue with the attached vessels was serially sectioned disclosing in its entirety a saccular aneurysm that had ruptured at the base rather than the dome. The histology of the hemostatic process was clearly depicted.

Need For Information

✓ Saccular aneurysm associated with segmental duplication (also called “fenestration”) of the basilar artery is an anomaly that results from an embryonic fault. Reports of the treatment of the aneurysmal component have only recently appeared in the neurosurgical literature, and little has been written on the morphology of this anomaly. This study answers the need for information about its structure to the extent permitted by the examination of a single specimen. The specimen was obtained at postmortem examination. A cast of its interior features was made with a synthetic rubber. After the cast was removed, the entire anomaly was serially sectioned for histological study. Defects in the wall of the basilar artery were seen microscopically at each end of the fenestration. At the extensive proximal defect, a saccular aneurysm arose that bulged into the window between the two limbs of the segmental duplication and also presented dorsally and ventrally. It had fatally ruptured. The manner in which the fenestration was formed by intraluminal septa was also revealed.

✓ The authors report a case of subarachnoid hemorrhage in an 11-month-old infant with tragic outcome. Radiological investigation showed an anterior communicating aneurysm, and postmortem examination confirmed the aneurysm to be a so-called “berry” aneurysm. There were also typical signs of fibromuscular hyperplasia of the renal arteries. The microscopic findings are discussed. In view of the rarity of both aneurysms and fibromuscular hyperplasia in such a small child, a possible association of these entities suggested by several earlier investigators is reviewed.

✓ A patient with subarachnoid hemorrhage was found to have electrocardiographic abnormalities resembling an acute myocardial infarction as well as left ventriculographic findings of cardiac dysfunction. These cardiac abnormalities resolved following surgical clipping of the aneurysm and the patient recovered well from the operation. She died 2 months later from cancer and a postmortem examination at that time revealed no evidence of myocardial necrosis. In this report, the authors discuss coronary vasospasm and reversible postischemic “stunned myocardium,” a condition that has not been considered previously in relation to subarachnoid hemorrhage.

✓ The majority of patients with intracranial hemorrhage associated with moyamoya disease have been described as having subarachnoid hemorrhage (SAH), but it seems doubtful that moyamoya disease causes primary SAH. Computerized tomography (CT) has revealed that most of the hemorrhage found in cases of moyamoya disease is intracerebral or intraventricular. The authors have reviewed 54 cases of intracranial hemorrhage confirmed by CT, including nine of their own, and found that in all but one the bleeding was intracerebral or intraventricular. The single case of SAH was due to rupture of a saccular aneurysm associated with moyamoya disease. It may be concluded from these results that moyamoya disease does not cause primary SAH per se.

✓ A 15-year-old youth presented with a history and computerized tomography picture of subarachnoid hemorrhage. Conservative management was undertaken after failure to demonstrate an aneurysm. Reevaluation and operation 15 months later disclosed a firm leathery schwannoma intimately related to the frontal lobe and extending into the cortex in the Virchow-Robin spaces.

✓ Forty-two patients with aneurysm-induced third nerve palsy are described. After carotid ligation, 58% showed satisfactory and 42% unsatisfactory functional recovery. In some patients the deficit continued to increase even after carotid ligation. Early ligation provided a better chance of recovery of third nerve function. Patients in whom third nerve palsy began after subarachnoid hemorrhage had a poor prognosis. No relationship was noted between the size of the aneurysm and the recovery of third nerve function.

✓ A series of 35 patients with 36 giant aneurysms is presented. Thirteen patients presented following subarachnoid hemorrhage (SAH) and 22 with evidence of a space-occupying lesion without recent SAH. The preferred technique of temporary trapping of the aneurysm, evacuation of the contained thrombus, and occlusion of the neck by a suitable clip is described. The danger of attempted ligation in atheromatous vessels is stressed. Intraoperatively, blood pressure was adjusted to keep the general brain circulation within autoregulatory limits. Direct occlusion of the aneurysm was possible in over 80% of the cases. The mortality rate was 8% in 36 operations. Six percent of patients had a poor result. Considerable improvement in visual loss was evident in six of seven patients in whom this was a presenting feature, and in four of seven with disturbed eye movements.
