The selecting criteria before surgery were essentially clinical (association of gait disturbances, dementia and urinary incontinence, positive lumbar puncture withdrawal test) in consideration with the retrospective and cooperative study of this series. Hydrocephalus had an etiology in 23 cases (50%): 4 cases of trauma (8%), 9 cases of tumors (20%), 9 cases of subarachnoid haemorrhage (20%) and 1 case of infection (2%). The average follow-up is 17 months (median: 12 months). 20 patients (43.5%) have an excellent result (normal life), 16 patients (34.8%) have a good result (residual symptomatology compatible with a self-governing life), 5 patients (10.9%) have a poor result (residual symptomatology non compatible with a self-governing life), 2 patients (4.3%) have a bad result (unchanged symptomatology). 3 patients died after the surgical procedure. 3 patients had an infectious complication of their shunt (actuarial risk of infectious complication at one year and a half: 7%). 2 patients presented a non infectious complication, one chronic subdural hematoma and one bad insertion of the proximal catheter (actuarial risk of mechanical complication at one year and a half: 4.4%). | lld:pubmed |
