Background: Intraventricular hemorrhage is a neurosurgical emergency, and a dangerous condition associated with high morbidity and mortality. Previously, hematoma evacuation is generally executed by external intracranial drainage (EVD) or surgical evacuation. Nowadays, endoscopic evacuation is emerging as a good alternative because it brings relatively less invasion and injury. However, successful endoscopic evacuation requires skilled manipulation of endoscopic devices and the evidence supporting its efficacy differs in different reports.
Aim: To improve the technique usage and provide more evidence of endoscopic evacuation efficacy, we summarize our surgical experience and compared the outcomes of the endoscopic evacuation with EVD using real-world data.
Methods: We retrospectively studied 96 consecutive patients with intraventricular hemorrhage who underwent either endoscopic surgery (n = 43) or non-endoscopic surgery (n = 53) for hemorrhage evacuation between November 2013 and September 2019 in our center. Patients' conditions prior to and after the operation were evaluated and analyzed to assess the efficacy of the operation. The consciousness status improvement and perioperative in-hospital parameters in the two types of operation groups were assessed and compared.
Results: Patients in the endoscopic and non-endoscopic groups presented with a similar state of consciousness, with a comparable Glasgow Coma Scale (GCS) index. The average operation time of the endoscopic group was longer than that of the non-endoscopic group (median 2.42 h vs 1.08 h, P < 0.001). Although the endoscopic group was older and had a baseline Graeb score that indicated more severe hemorrhage than the non-endoscopic group (Graeb median: Endoscopic group = 9 vs non-endoscopic group = 8, P = 0.023), the clearance rate of hematoma was as high as 60.5%. Both the endoscopic and non-endoscopic groups showed an improved GCS index after surgery. However, this improvement was more marked in patients in the endoscopic group (median improvement of GCS index: Endoscope group = 4 vs non-endoscopic group = 1, P < 0.001). Additionally, the endoscopic group had a lower Graeb score than the non-endoscopic group after the operation. The intensive care unit stay of the endoscopic group was significantly shorter than that of the non-endoscopic group (median: endoscopic group = 6 d vs non-endoscope group = 7 d, P = 0.017).
Conclusion: Endoscopic evacuation of intraventricular hemorrhage was generally an effective and efficient way for hemorrhage evacuation, and contributed remarkably to the improvement of consciousness in patients with intraventricular hemorrhage.
