3D ultrasound (US) is a convenient tool for guiding the resection of low-grade gliomas, seemingly without deterioration in patients’ quality of life. This article offers an update of the intraoperative workflow and the general principles behind the 3D US acquisition of high-quality images.The authors also provide case examples illustrating the technique in two small mesial temporal lobe lesions and in one insular glioma. Due to the ease of acquiring new images for navigation, the operations can be guided by updated image volumes throughout the entire course of surgery. The high accuracy offered by 3D US systems, based on nearly real-time images, allows for precise and safe resections. This is especially useful when an operation is performed through very narrow transcortical corridors.

Local Anesthetic Injection

Background: Percutaneous cryoneurolysis provides prolonged postoperative analgesia by placing a probe adjacent to a peripheral nerve and cooling the probe tip, inducing a reversible block that lasts weeks to months. Unfortunately, freezing the nerve can produce significant pain. Consequently, local anesthetic is generally applied to the nerve prior to cryoneurolysis, which, until now, required an additional needle insertion increasing both the risks and duration of the procedure. Case Presentation: Three patients underwent ultrasound-guided percutaneous cryoneurolysis of either the sciatic and saphenous nerves or the femoral nerve. In all patients, the local anesthetic injection and cryoneurolysis were accomplished with a single needle pass using the novel probe introducer. Conclusion: This introducer allows perineural local anesthetic injection followed immediately by cryoneurolysis, thereby sparing patients a second skin puncture, lowering the risks of the procedure, and decreasing the overall time required for cryoneurolysis.

Abstract Objective The anatomical landmarks method is currently the most widely used technique for epidural needle insertion and is faced with multiple difficulties in certain patient populations. Real-time ultrasound guidance has been recently used to aid in epidural needle insertion, with promising results. Our aim was to test the feasibility, success rate, and satisfaction associated with a novel real-time ultrasound-guided lumbar epidural needle insertion in the transverse interlaminar view. Design Prospective descriptive trial on a novel approach. Setting Operating room and preoperative holding area at a tertiary care hospital. Subjects Adult patients presenting for elective open prostatectomy and planned for surgical epidural anesthesia. Methods Consented adult patients aged 30–80 years scheduled for open prostatectomy under epidural anesthesia were enrolled. Exclusion criteria included allergy to local anesthetics, infection at the needle insertion site, coagulopathy, and patient refusal. A curvilinear low-frequency (2–5 MHz) ultrasound probe and echogenic 17-G Tuohy needles were used by one of three attending anesthesiologists. Feasibility of epidural insertion was defined as a 90% success rate within 10 minutes. Results Twenty-two patients were enrolled into the trial, 14 (63.6%) of whom found the process to be satisfactory or very satisfactory. The median time to perform the block was around 4.5 minutes, with an estimated success rate of 95%. No complications related to the epidural block were observed over the 48 hours after the procedure. Conclusions We demonstrate the feasibility of a novel real-time ultrasound-guided epidural with transverse interlaminar view.

Main Components

In needle-based medical procedures, beveled tip flexible needles are steered inside soft tissue to reach the desired target locations. In this paper, we have developed an autonomous image-guided needle steering system that enhances targeting accuracy in needle insertion while minimizing tissue trauma. The system has three main components. First is a novel mechanics-based needle steering model that predicts needle deflection and accepts needle tip rotation as an input for needle steering. The second is a needle tip tracking system that determines needle deflection from the ultrasound images. The needle steering model employs the estimated needle deflection at the present time to predict needle tip trajectory in the future steps. The third component is a nonlinear model predictive controller (NMPC) that steers the needle inside the tissue by rotating the needle beveled tip. The MPC controller calculates control decisions based on iterative optimization of the predictions of the needle steering model. To validate the proposed ultrasound-guided needle steering system, needle insertion experiments in biological tissue phantoms are performed in two cases–with and without obstacle. The results demonstrate that our needle steering strategy guides the needle to the desired targets with the maximum error of 2.85[Formula: see text]mm.
