Abstract

Overview: Intraoperative ultrasound (IOUS) is a relatively new technique in Vietnam, especially in brain and spinal tumor surgery. It provides real-time imaging to assist with surgical orientation, tumor margin delineation, and assessment of residual tumor. Objective: To evaluate the initial experience with intraoperative ultrasound (IOUS) in neurosurgery, focusing on cases of brain and spinal cord tumors. Method and material: IOUS was performed in 15 surgical cases (10 brain tumors, 5 spinal cord tumors). Ultrasound was used to localize lesions, delineate tumor margins, and assess residual tissue. Data were collected in a qualitative descriptive manner based on intraoperative clinical observations. Results: IOUS provided real-time imaging, supporting surgical orientation and allowing flexible adjustment of surgical strategies. In tumors with well-defined margins (such as meningiomas and intramedullary spinal tumors), IOUS offered clear visualization and facilitated assessment of resection extent. In spinal tumors, IOUS helped accurately identify the tumor–cord interface, aiding in safe dissection. Discussion: IOUS is a feasible and valuable imaging tool in neurosurgery, particularly in settings without access to neuronavigation systems or intraoperative MRI. However, certain technical limitations were observed, including image artifacts caused by blood clots, air, and probe manipulation. Further research and training are necessary to optimize the clinical application of IOUS.
