Diagnostic-therapeutic ventriculocystostomy.

Simple diagnostic-therapeutic ventriculocystostomy is described. Arachnoid, intracerebral, or intraventricular cysts are permanently connected with the ventricles by a Kifa red catheter with spirally situated holes. The pressure balance and the connection with a physiological space for resorption is maintained in this simple way. Twenty patients have been operated on over a 2-year period with good results.

Emergency internal carotid artery desobliteration in patients with severe neurological deficit.

7 patients evaluated for deep neurological deficit due to internal carotid artery stenosis or occlusion underwent emergency carotid artery desobliteration. At the time of the operation, which was performed 6-10 hours after the onset of signs, all the patients were hemiplegic and, when dominant side affected, aphasic, 5 of them have had the level of consciousness slightly depressed. The patients were divided into two groups: 1. Completed deficit with typical sudden onset of disease, without fluctuation (4 patients). 2. Progressing deficit with rapid downhill course despite medical therapy (3 patients). In the group with completed stroke one patient died, later three experienced modest improvement. In the group with progressing stroke two patients are neurologically intact, the last one in full-activity with mild hemiparesis. It is stated that those with completed stroke are unfavourable candidates for surgery. Patients with progressing stroke should be submitted to surgery before the deficit becomes stabilized.

Ventricular haemorrhage.

Our clinical experiments with a simulation of intracerebral haematomas in hypertonics and our clinical experiences lead us to the conclusions that a pure isolated ventricular haemorrhage causes according to the quantity of blood only a gradual increase of intracranial pressure. Pia's three classical types are marking points on the continual scale from haematocephalus totalis to haemorrhage. Haematoma rupture into the ventricles is to a certain degree a beneficial increase of intracranial volume reserve. Pia's types can be supplemented with the so called "pseudoventricular haemorrhage" in which the haematoma only bulges into the ventricle and is covered by ependym. Hypertonics with the bleeding into basal ganglias do not die as a result of blood bursting into the ventricles, but owing to secondary brainstem compression. Ventricular haemorrhage is therefore not decisive for the indication of an operation. In the case of a pure ventricular haemorrhage with signs of intracranal hypertension a bilateral external drainage should be carried out.
