To explore the application value of intraoperative ultrasound in lateral ventricle space occupying.

Twenty-eight patients with lateral ventricular space occupying lesions in the Neurosurgery Department of Third People’s Hospital Affiliated to Wuhan Jianghan University were selected from July 2015 to July 2019. All patients underwent localization and qualitative diagnosis by intraoperative ultrasonography before and after surgical resection, which guided clinicians to select appropriate surgical pathways and evaluated the extent of tumor resection.

In 28 patients with lateral ventricular space occupying, 10 cases (35.7%) had unclear boundary, 12 cases (42.9%) had edema zone around lesions and 14 cases (50%) had blood flow signals in lesions. Abnormal blood flow signals were found in 7 cases of 16 patients with WHO grade Ⅰ and 10 cases of 12 patients with WHO grade above Ⅰ, and there was a significant difference in the detection rate between the two groups (χ²=114.5, P=0.035). One patient died of early postoperative because of rebleeding with massive cerebral infarction; 27 patients were followed up for half a year, the neurological symptoms were significantly improved, and there was no new neurological dysfunction. Postoperative MRI reexamination showed total resection in 25 cases and minor residual in 2 cases. The overall complete resection rate guided by intraoperative ultrasound was 92.59%.

Intraoperative ultrasound has the advantages of real-time, convenience, visual image, accurate location and repeatable examination. It has unique advantages in lateral ventricle space-occupying surgery. It is helpful for full preoperative preparation, total resection of tumors, protection of function and blood vessels.
