Risk factors of shunt-dependent hydrocephalus after aneurysmal subarachnoid hemorrhage / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To investigate risk factors for the occurrence of shunt-dependent hydrocephalus in patients with aneurysmal subarachnoid hemorrhage (aSAH).</p><p><b>METHODS</b>A cohort of 136 consecutive patients who were treated for ruptured aneurysms within 72 h after onset of aSAH from January 2011 to January 2013 were retrospectively analyzed. Lumbar drainage was performed during the surgery in all patients. The risk factors of shunt-dependent hydrocephalus were analyzed.</p><p><b>RESULTS</b>Of 136 patients, 23 (16.91%) underwent shunt operation to treat shunt-dependent hydrocephalus. Univariate analysis showed that Hunt-Hess grade at admission (P<0.01), Fisher grade (P<0.01), the presence of intraventricular hemorrhage (P<0.01), location of ruptured aneurysm (P=0.001), and the average daily volume of cerebrospinal fluid drainage (CSF) (P=0.047) were associated with shunt-dependent hydrocephalus.</p><p><b>CONCLUSION</b>The aSAH patients with poor Hunt-Hess grade at admission, high Fisher grade, the presence of intraventricular hemorrhage, ruptured aneurysm in posterior circulation, and abnormal average daily volume of CSF are more likely to develop shunt-depended hydrocephalus.</p>
