Brain edema and/or acute hydrocephalus are common features that limit working space during early surgery of aneurysmal subarachnoid hemorrhage (aSAH). Intraoperative ventriculostomy offers an immediate brain relaxation. However, management and complications related to the routine use of intraoperative external ventricular drainage (iEVD) are not well investigated.
Background: Brain edema and/or acute hydrocephalus are common features that limit working space during early surgery of aneurysmal subarachnoid hemorrhage (aSAH). Intraoperative ventriculostomy offers an immediate brain relaxation. However, management and complications related to the routine use of intraoperative external ventricular drainage (iEVD) are not well investigated. Methods: We retrospectively reviewed all patients who were treated with pterional craniotomy and clipping for ruptured anterior circulation aneurysms in our center between 2012 and 2019. We included in this study all patients submitted to iEVD using the Paine’s point on the side of craniotomy. Indication for positioning of an iEVD was given in all cases whenever initial cisternal dissection was hampered by the lack of cerebrospinal fluid (CSF) circulation due to SAH and/or hydrocephalus. Results: In the study period, 162 patients with aSAH underwent surgical clipping. In 103 patients, an iEVD was used. The overall rate of iEVD-related complications was 6.7%, including 3 cases of catheter misplacement, one case of catheter obstruction, one case of related hemorrhage, and 2 cases of infection. The rate of shunt-dependent hydrocephalus was 16.5% (17/103 patients). Conclusion: In our experience, iEVD is a safe technique that facilitates dissection during early surgery for intracranial ruptured aneurysms, without requiring an additional burr hole procedure.

Abstract
Background: Brain edema and/or acute hydrocephalus are common features that limit working space during early surgery of aneurysmal subarachnoid hemorrhage (aSAH). Intraoperative ventriculostomy offers an immediate brain relaxation. However, management and complications related to the routine use of intraoperative external ventricular drainage (iEVD) are not well investigated. Methods: We retrospectively reviewed all patients who were treated with pterional craniotomy and clipping for ruptured anterior circulation aneurysms in our center between 2012 and 2019. We included in this study all patients submitted to iEVD using the Paine’s point on the side of craniotomy. Indication for positioning of an iEVD was given in all cases whenever initial cisternal dissection was hampered by the lack of cerebrospinal fluid (CSF) circulation due to SAH and/or hydrocephalus. Results: In the study period, 162 patients with aSAH underwent surgical clipping. In 103 patients, an iEVD was used. The overall rate of iEVD-related complications was 6.7%, including 3 cases of catheter misplacement, one case of catheter obstruction, one case of related hemorrhage, and 2 cases of infection. The rate of shunt-dependent hydrocephalus was 16.5% (17/103 patients). Conclusion: In our experience, iEVD is a safe technique that facilitates dissection during early surgery for intracranial ruptured aneurysms, without requiring an additional burr hole procedure.File | Dimensione | Formato | |
