[The management of subarachnoid hemorrhage in pregnancy].

Subarachnoid haemorrhage (SAH) from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. Authors critically analyzed 12 cases of verified SAH during pregnancy from an 11 identified and 1 unidentified cerebral vascular malformation. Aneurysms were responsible for SAH in 7, and arteriovenous malformations in 4 patients. Subarachnoid haemorrhage occurred during I trimester in 2, II trimester in 3, III trimester in 6 patients and after cesarean delivery in 1 case. We conclude that the decision to operate after SAH during pregnancy should be based upon neurosurgical principles, whereas the cesarean delivery should be done in every pregnant patient with SAH.

[Spontaneous subarachnoid hemorrhage in pregnancy].

Subarachnoid haemorrhage from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. The authors analyzed 11 cases of verified subarachnoid haemorrhage during pregnancy from 10 identified and 1 unidentified cerebral vascular malformation. The aneurysms were responsible for subarachnoid haemorrhage in 6, and arteriovenous malformation in 4 patients. We conclude that the decision to operate after subarachnoid haemorrhage during pregnancy should be based upon neurosurgical principles, whereas cesarean delivery should be done in every pregnant patient with subarachnoid haemorrhage.

[Angiomas of blood vessels supplying the basal ganglia and the diencephalon].

The author discusses the problem of surgical treatment of intracranial angiomas situated in basal ganglia and diencephalon. Vascular malformations in this area were found in 7.5% of cases in a group of 80 patients with intracranial angiomas. In all 6 cases the onset of the disease was sudden with meningocerebral haemorrhage, prolonged coma and hemiplegia. The malformations had usually the features of arteriovenous angioma. The afferent vessels come usually from the medial short and long vessels branching off from the anterior and middle cerebral arteries, the choroid arteries and the posterior communicating artery. The author isolated two types of malformations differing in their situation, shape and range of vascularization. In the "subventricular" type situated within the nucleus caudatus and lenticularis, internal capsule and thalamus the malformation can be exposed well from the approach through the lateral ventricle. The angiomas situated nearer to the base of hemisphere (the parabasal type), in the diencephalon, in the area of the olfactory triangle, substantia perforata anterior and even crus cerebri can be exposed best using the subfrontal approach. The author believes that in many cases of these malformations regarded usually as inoperable, radical operation can be done with selective removal of angioma by means of microsurgery. This procedure was applied in 2 cases (Fig. 2 and 3).

[Contrast ventriculography using dimer-X].

The authors report the results of 100 Dimer-X ventriculographies mainly in cases of midline tumours. The value of tomography for the diagnosis of tumours is stressed. Besides that, the contrast was used for visulization of intracerebral cavities, emptied abscesses, cavities in astrocytomas and intracerebral haematoma. Complications following the use of Dimer-X for direct filling of the ventricular system are discussed.

[Congenital carotid-sinus cervical-sagittal fistula].

The reported case presented an unusual form of congenital carotid-sagittal communication. Clinical findings included: except vascular murmur over the skull a characteristic syndrome consisting of of epleptic seizures, hemiparesis, aphasia and dementia. The communication was excised radically in its central and peripheral parts. The segment corresponding to the main trunk of the middle cerebral artery was narrowed by means of bipolar coagulation. Postoperative angiography and disappearance of most neurological signs after the operation showed that the chronically ischaemic parts of the brain resumed their functions.

[Aneurysm situated within the optic nerve].

A case of carotid-ophthalmic aneurysm of unusual location in the optic nerve is reported. The development of the disease was sudden: pain in the eye was followed by unilaternal blindness and manifestations of subarachnoid haemorrhage. The optic nerve was dilated balloon-like, cyanotic and vigorously pulsating. It was divided longitudinally and the aneurysmatic sac was exposed from the nerve. A vascular clip was put on its peduncle communicating with the cervico-ophthalmic portion of internal carotid artery. Despite preserved patency of the ophthalmic artery and partial continuity of the optic nerve, the vision of the eye didn't improve.
