High-frequency intraoperative ultrasound (ioUS) guided surgery of superficial intracerebral lesions via a single burr hole approach

Purpose: Feasibility study to minimize the approach in surgery of superficial intracerebral lesions to a single burr hole using high-frequency intraoperative ultrasound (hfioUS). Material and methods: Using a standard navigation system, placement of a single burr hole was performed and ultrasound scanning with the L15 – 7 hfioUS probe (iU22 Ultrasound System, Philips) was used through the burr hole to display the lesion in real-time intermittently throughout the entire procedure. In a cohort of 21 consecutive patients with 22 various intracerebral lesions including metastasis (n = 8), gliomas (n = 7), infections…
