In a group of 27 patients with spontaneously developing intracerebal haematomas in three cases small angiomas of the brain were demonstrated at angiography, operation and microscopic examination. In two cases presence of such microangioma was suspected. In all five patients good results were obtained after operation. Attention is called to difficulties in clinical, angiographic and even surgical diagnosis of cerebral microangioma.
The problem of cerebral arteriospasm following rupture of intracranial aneurysm is analysed comprehensively in the clinical, angiographic, electroencephalographic and, particularly, neurosurgical aspects in a group of 51 cases. Seventy-six patients without arteriospasm after aneurysm rupture served as controls. It was found that cerebral arteriospasm caused deterioration of the preoperative condition of the patients with subarachnoid haemorrhage and influenced unfavourably the results of surgical treatment of patients with intracranial aneurysm.
In a 47-year-old women two subarachnoid haemorrhages developed with paralysis of the right oculomotor nerve. A big aneurysm on the right internal carotid artery was closed with a clip from intracranial approach. Seven months later the left oculomotor nerve was paralysed without haemorrhage. Another operation was done on the contralateral side clipping the aneurysm on the left carotid artery. The patient tolerated well both operations. The necessary of control postoperative angiography is stressed.
Seven surgical cases of large aneurysms (over 10 mm in diameter) are described. In 5 cases the neck of the aneurysm was closed, in 2 the aneurysmal sac was excised. Large aneurysms of the middle cerebral artery cause great difficulties in surgical closure of their necks with routinely used clips. Late results of treatment were very good in 5 cases.
