Table 1.
Characteristics of patients with spontaneous subarachnoid hemorrhage who underwent aneurysmal clipping classified by ventriculo-peritoneal shunt operation.
Fig 1.
(A, C, E) Bar plot showing the variations of laboratory parameters after SAH occurrence. A, sodium (normal: 135–145 mEq/L); C, potassium (normal: 3.5–5.0 mmol/L); E, fasting glucose except for preoperative glucose (normal 70–126 mg/dL). (B, D, F) Kaplan-Meier curves showing the cumulative hazard ratio of V-P shunt after clipping for SAH according to laboratory parameters from POD 1 to POD 12–16. B, sodium; D, potassium; F, glucose.
Table 2.
Variations of laboratory parameters as time increases in patients with subarachnoid hemorrhage who underwent aneurysmal clipping.
Fig 2.
Variations of various laboratory parameters after subarachnoid hemorrhage occurrence based on shunt dependency: A, sodium; B, potassium; C, glucose; D, osmolarity.
*p < 0.05, ** < 0.01, *** < 0.001.
Fig 3.
Receiver operating characteristic curve for shunt-dependent hydrocephalus after subarachnoid hemorrhage occurrence from POD 1 to POD 12–16 based on the following factors: A, sodium; B, potassium; C, glucose; D, osmolarity. POD = postoperative day.
Fig 4.
Kaplan-Meier curves showing the cumulative hazard ratio of V-P shunt after clipping for SAH according to several laboratory parameters from POD 1 to POD 12–16.
A, Total; B, sodium; C, potassium; D, glucose. V-P = ventriculo-peritoneal; SAH = subarachnoid hemorrhage; POD = postoperative day.
Fig 5.
Forest plot of estimates from the multivariate logistic regression of shunt-dependent hydrocephalus according to the potential predictive factors (adjusted for sex, age group, Hunt-Hess grade, modified Fisher grade, IVH, ICH, EVD, operation type, white blood cell, sodium, potassium, glucose, blood urine nitrogen, creatinine, osmolarity, and albumin).
IVH = intraventricular hemorrhage; ICH = intracerebral hemorrhage; EVD = external ventricular drainage.
