“…A study of patients with intracranial aneurysms showed that neuronavigation increased the safety for surgery and the precise localization of aneurysms (13). Similar effects have been achieved in patients with distal intracranial aneurysms, where neuronavigation combined with intraoperative ultrasound can precisely localize distal aneurysms of the middle cerebral artery and improve patient prognosis (14). However, the application of neuronavigation relies on a cranial Magnetic resonance imaging (MRI), which makes it difficult to pinpoint the exact location of small aneurysms.…”

Background: Distal intracranial aneurysms are often located deep in the lateral or longitudinal fissure pool or brain parenchyma, lacking a fixed anatomical location. Precise intraoperative localization of distal intracranial aneurysms is a problem that plagues neurosurgeons. Studies have shown that neuronavigation and Computed Tomography (CT) three-dimensional angiography can significantly improve the accuracy of intracranial aneurysm surgery. However, their values in the distal intracranial aneurysm surgery remain unknown. The objective of this study was to explore the application value of neuronavigation combined with CT three-dimensional angiography in distal intracranial aneurysm surgery.Methods: 112 patients admitted to our hospital for intracranial distal aneurysm surgery were retrospectively collected and divided into an observation group (n=51) and a control group (n=61) according to the surgical method received by the patients. The observation group underwent clipping treatment based on neuronavigation combined with CT three-dimensional angiography, and the control group received clipping treatment under the guidance of CT angiography. Both groups were observed for the accuracy of localization and approach design, duration of surgery, intraoperative bleeding volume, Glasgow Outcome Scale (GOS), National Institute of Health Stroke Scale (NIHSS), length of hospital stay, and complications.Results: Compared with the control group, the localization accuracy of patients in the observation group was significantly increased (94.12% vs. 78.69%, P=0.020), and the accuracy of approach design was markedly improved (90.20% vs. 72.13%, P=0.017). Furthermore, the length of hospital stay in the observation group was notably reduced compared with the control group (8.12±2.12 vs. 8.99±1.87 d, P=0.023). There was no statistical difference in the NIHSS scores between the two groups before treatment and at 3 days after treatment (P>0.05). However, compared with the control group, the NIHSS score was significantly reduced in the observation group at 28 days after surgery (4.10±2.48 vs. 6.30±3.20, P=0.000). There were no statistically significant postoperative complications in either group (P>0.05).Conclusions: Neuronavigation combined with CT three-dimensional angiography can enhance the accuracy of localization and approach design in intracranial distal aneurysm surgery, improve patient nerve function, and is worth promoting.
