Objectives : A postoperative hydrocephalus is compromises the clinical outcome of patients with aneurysmal clippings as one of the major complications of SAH. Subdural hygroma is often complicated after aneurysmal clippings, which subsides spontaneously as simple hygroma, or progresses to shunt-dependent hydrocephalus (SDHC). To predict development of SDHC from the hygroma, and to improve clinical outcome of patients with aneurysmal clippings, we analyzed clinical predisposing factors between 2 subgroups, simple hygroma and SDHC. Patients and Methods : A retrospective study of 232 consecutive cases of clipped aneurysmal patient was undertaken in our hospital for last two years. The 46 patients(19.8%) developed hygromas after aneurysmal clippings. There were 22 cases with simple hygroma(9.5%), and 24 patients with SDHC(10.3%). Comparison of 2 subgroups was made for various clinical and radiological factors. Results : Older age(p=0.03), poor preoperative clinical grade(p=0.01), high Fisher grade(p=0.005), large amount of hygroma(p=0.014) and increased size of lateral ventricle ipsilateral to hygroma(p=0.001) were correlated significantly with SDHC. There was no statistical significance in sex, aneurysmal location and presence of acute preoperative ventricular dilatation between 2 subgroups. Conclusion : The clinical factors, such as older age, poor preoperative clinical grade, high Fisher grade, large amount of hygroma and increased size of lateral ventricle ipsilateral to hygroma showed statistical sinificance for differentiating SDHC from simple hygroma.
