Basivertebral nerve ablation technique.

Chronic low back pain represents a leading cause of global disability, but can often be complex in etiology, with multiple pain generators contributing to patient discomfort. Anterior column low back pain involves the vertebral bodies and discs, with the vertebral body endplates now known to be a significant pain generator. Vertebrogenic low back pain secondary to irritation of the basivertebral nerve presents as axial discomfort, worse with forward flexion, and with concomitant Type I or II Modic changes on MRI.

Vertebral augmentation: How we do it.

Vertebral augmentation consists of minimally invasive techniques indicated in the treatment of vertebral compression fractures (VCFs). These compression fractures cause vertebral body height loss and consequent significant pain and are most frequently the result of osteoporosis, cancer metastasis, or trauma. The deleterious effects of VCFs often compound, as greater load-bearing stress is transferred to the remaining healthy vertebrae.

Rotational thrombectomy versus balloon maceration in dialysis access salvage.

Background: Although end stage renal disease patients who undergo hemodialysis frequently experience dialysis-associated thrombotic complications, there remains a paucity of literature comparing the efficacy of different endovascular salvage techniques for grafts and fistulas. This study aims to compare primary patency in dialysis access following salvage mechanical thrombolysis/thrombectomy with a rotational thrombolysis device versus balloon maceration.

Methods: Using a database of patient records at a tertiary medical center, all patients who underwent rotational thrombectomy with the Cleaner XT™ Rotational Thrombectomy System for endovascular salvage of arteriovenous fistula or arteriovenous graft from August 2016 to July 2022 were included in the population.

Fixed-time synchronization of complex-valued neural networks for image protection and 3D point cloud information protection.

This paper studies the fixed-time synchronization (FDTS) of complex-valued neural networks (CVNNs) based on quantized intermittent control (QIC) and applies it to image protection and 3D point cloud information protection. A new controller was designed which achieved FDTS of the CVNNs, with the estimation of the convergence time not dependent on the initial state. Our approach divides the neural network into two real-valued systems and then combines the framework of the Lyapunov method to give criteria for FDTS.

Evaluation of paravertebral blocks in improving post-procedural pain and decreasing hospital admission after microwave ablation of liver tumors.

Although ablations are performed with conscious sedation or general anesthesia, microwave ablations can be painful post procedure. Newer analgesic modalities, including regional blocks, have promoted the proliferation of less invasive anesthesia care for ablative procedures. This study evaluates whether bilateral paravertebral blocks reduce the need for additional analgesics in comparison to unilateral blocks in microwave ablations.

New insights into atomic layer BiOBr quantum dot/ZnAl-LDH composites in photocatalytic water treatment: Performance and mechanism.

Assuming that the network is structurally balanced, bipartite synchronization can be reached with some conditions and coordinate transform criterion. Then, Based on Lyapunov stability theory, some important norms are established.

Finite-Time Synchronization of Neural Networks With Proportional Delays for RGB-D Image Protection.

Since the depth information of images facilitates the analysis of the spatial distance of objects in computer vision applications, it is necessary to protect the image depth information. Thus this article proposes a novel red-green-blue-depth (RGB-D) image protection algorithm, which is implemented with the finite-time synchronization (FTS) of neural networks (NNs) with proportional delays via the quantized intermittent control to derive the system synchronization criterion based on Lyapunov stability theory. The performance of RGB-D image protection depends on the synchronization error of the system by driving the system sequence to encrypt the RGB-D image and responding to the system sequence to decrypt the encrypted image.

Image-Guided Radiofrequency Ablation for Joint and Back Pain: Rationales, Techniques, and Results.

Image-guided minimally invasive radiofrequency ablation (RFA) of sensory nerves has emerged as a treatment option for pain and swelling associated with advanced symptomatic joint and spine degeneration to bridge the gap between optimal medical therapy and surgical treatments. RFA of articular sensory nerves and the basivertebral nerve use image-guided percutaneous approaches resulting in faster recovery time and minimal risks. The current published evidence indicates clinical effectiveness; however, further research must be performed comparing other conservative treatments with RFA to understand further its role in different clinical settings, such as osteonecrosis.
