Explore Intraoperative Ultrasound In The Removal Of Intracranial Subcortical Lesion And The Clinical Application Value Of Cavernous Hemangioma

The study was divided into two parts:(1)The application of intraoperative ultrasound in the resection subcortical occupying lesion.(2)The application of intraoperatice ultrasound in the resection cavernous hemangioma.Part ? The application of intra-operative ultrasound in the resection subcortical occupying lesion Objective: To investigate the clinical application value of intra-operative ultrasound(IOUS) in the resection of subcortical occupying lesions.Methods: Thirty-nine intracranial space-occupying lesions in 35 patients were located accurately to find the optimal operative approach via using IOUS, and guided to resect intracranial lesions in the whole process of operation. Simultaneously, resection range and residuals of lesions were observed clearly.Results: All the lesions were located exactly and resected totally. Twenty-eight focuses in non functional area and seven focuses in functional area were resected totally and no significant focal neurological dysfunction was observed postoperatively. Acroparalysis in four patients became more serious compared to preoperative situation. But myodynamia restored to preoperative level six months later via rehabilitation training.Conclusions: Subcortical occupying lesions were located exactly and guided the optimal operative approach to resect the lesions via IOUS. Not only IOUS protected normal nerve and vascular structures from damaging and improving the total removal rate and the effect of operation, but also reduced the recurrence rate and complications. The instantaneity, safety and practicability of IOUS exerted the clinical application prospect and value. Part ΙΙ The application of intraoperatice ultrasound in the resection cavernous hemangioma.Objective:To investigate the clinical value of intraoperative real-time ultrasound in resection of cerebral cavernous hemangioma.Methods: Thirty three patients with cerebral cavernous hemangioma were invided to two groups whether by introperative ultrasoud monitoring. Guided by ultrasound group of 16 cases, intraoperative ultrasound examination showed cavernous hemangioma of the location, size, shape and its relationship with the surrounding tissue, make the best surgical approach, and through real-time scanning, monitoring lesion resection of lesion resection after ultrasonic probe has a secondary bleeding again and residual lesions.Another 17 cases for control group, according to the traditional surgery operation.Compare two groups of patients with focal ablation time, resection and complications.Results: The focuses of two groups were all successfully resected and there was no fatal case in both groups.The MRI and pathology examination diagnosis coincidence rate was 100%. The intraoperative ultrasound exactly indicated the position, size and modality of cavernous hemangioma. All focuses were found through operating microscope. The operating time of ultrasonic group was obviously shorter than that of control group.The incidence of postoperative complications in ultrasonic group was significantly lower than that of control group.Conclusion: Intraoperative real-time ultrasound guided auxiliary for precise localization of lesions in the cerebral cavernous hemangioma, improve the accuracy of the operation and security, to help the performer to choose the best approach, defend the surrounding brain tissue to the greatest extent, shorten the operation time, reduce the postoperative complications and poor prognosis, in nerve microsurgical operation has good practicability and extensive application prospect.
