[Immediate and late results of surgical treatment of hydrocephalus after subarachnoid hemorrhage].

During the period from January 1st 1983 up to the end of April 1989 in the Neurology Department and the Neurosurgery Department 1417 patients were treated due to subarachnoidal hemorrhage. Among these patients in 275 cases the inner hydrocephalus was diagnosed using computer tomography (19.4%). In 17 cases (6.2%) hydrocephalus was treated surgically. In all patients the ventricle-atrial Pudenz valve was implanted; in 15 patients the valve was implanted for low pressure and in 2 for moderate pressure. The diagnostics was based on the computed tomography and angiography of cerebral vessels. In all cases large hydrocephalus was diagnosed (the anterior horn index in the computed tomography was below 3.0). The most frequent clinical symptoms were: urine incontinence (15 cases), disturbances of orientation (8 cases), akinetic mutism (8 cases) and paresis of extremities (7 cases). Above symptoms together with radiologic image presented indication for the valve implantation. Very good and good results were obtained in 13 patients, bad results in 2 cases, 2 patients died. Longer observation showed that 6 patients remain in satisfactory state, 3 patients are in bad state and 3 others died.
