Surgical intervention is suggested only when TSE exerts mass effect. The authors have found that many patients with TSE exerting mass effect have concomitant hydrocephalus. Patient experiencing this occurrence were studied, and the pathogenesis of this phenomenon was discussed in the context of recent advances in the understanding of CSF circulation.<\/jats:p><\/jats:sec>\n\nMethods<\/jats:title>\nDuring a 2-year period, the authors' institution treated 14 patients with TSE who developed hydrocephalus, after 1 of the patients suffered subdural drainage and other 13 received subdural peritoneal shunt (SPSs). Thirteen of those who had SPSs received programmable ventriculoperitoneal shunts (VPSs) for the hydrocephalus. The clinical characteristics as well as the imaging and operative findings of these patients were reviewed.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nAll patients with symptomatic TSE exerting mass effect received SPSs. All of these patients had a modified Frontal Horn Index of more than 0.33 at presentation, and high opening pressure on durotomy. Following a brief period (4\u20137 days) of clinical improvement, the condition of all patients deteriorated due to hydrocephalus. Programmable VPSs were inserted with the initial pressure set at approximately 8\u201310 cm H2<\/jats:sub>O according to opening pressure at ventriculostomy. Shunt valve pressure was gradually decreased to 5\u20137 cm H2<\/jats:sub>O, according to clinical and radiological follow-up.<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nElevated modified Frontal Horn Index in patients with TSE is suggestive of concomitant hydrocephalus. The authors propose that tearing of the dura-arachnoid plane following trauma contributes to TSE and may also impede CSF circulation, causing hydrocephalus. Shunt pressure was adjusted to relative low pressure, indicating the old age of the patients and poor reexpansion of brain parenchyma after the mass effect. Subdural peritoneal shunts and VPSs are indicated in those patients with TSE exerting mass effect with concomitant hydrocephalus.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2011.10.jns11711","type":"journal-article","created":{"date-parts":[[2011,12,16]],"date-time":"2011-12-16T15:05:00Z","timestamp":1324047900000},"page":"558-565","source":"Crossref","is-referenced-by-count":21,"title":["Treatment of patients with traumatic subdural effusion and concomitant hydrocephalus"],"prefix":"10.3171","volume":"116","author":[{"given":"Fon-Yih","family":"Tsuang","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, National Taiwan University Hospital, Taipei;"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abel Po-Hao","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Surgery, National Taiwan University Hospital, Yun-Lin Branch, Yun-Lin;"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Hsin","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Traumatology,"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo-Yu","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, and"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing-Er","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurology, Zhuchi Buddhist Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Kwang","family":"Tu","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, National Taiwan University Hospital, Taipei;"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuo-Chuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, National Taiwan University Hospital, Taipei;"},{"name":"Institute of Clinical Neuroscience, National Taiwan University, Taipei; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns11711","series-title":"Exp Eye Res","first-page":"585","article-title":"Removal of horseradish peroxidase and fluorescein-labelled dextran from CSF spaces of rabbit optic nerve.
