Cryoablation

atients with combat-related amputations frequently develop chronic neuroma pain that interferes with rehabilitation, prosthesis use, mobility, sleep, and quality of life. Cryoablation is a minimally invasive treatment that produces controlled nerve injury using extreme cold. Although the freezing effect is localized around the cryoprobe, axonal interruption followed by distal Wallerian degeneration may extend functional denervation distal to the ablation site. This study aims to compare two ultrasound-guided cryoablation strategies for chronic neuroma pain after combat-related amputation: cryoablation performed directly near the neuroma and cryoablation performed proximal to the neuroma along the affected nerve. The study will evaluate whether proximal nerve cryoablation produces greater or longer-lasting analgesic effects compared with perineuroma cryoablation.

The clinical study is titled the CRYONIC PROTOCOL, which stands for Cryotherapy for Neurolysis In Chronic Pain. It is structured as a prospective, multi-cohort observational study. Purpose of the Study: The overarching purpose of the CRYONIC PROTOCOL study is to assess the Correlation Between Diagnostic Nerve Block Response and Cryoneurolysis Outcome in Chronic Musculoskeletal Disorders. The study focuses on evaluating the effectiveness of ultrasound-guided peripheral nerve cryoneurolysis, a minimally invasive technique that uses extreme cold to induce temporary nerve blocks, for patients with treatment-resistant chronic musculoskeletal pain. The study also seeks to determine if cryoneurolysis itself leads to meaningful improvements in both pain intensity and functional ability in the included patient cohorts.

Using RBS as the navigation and treatment platform, precisely navigate to the target lesion. Utilize r-EUBS and nCLE to identify the lesion, and when the confocal AI model recognizes the lesion as malignant, perform a biopsy. Subsequently, under the guidance of OBCT, carry out ablation treatment of the lesion.

A registry to audit the current range of applications, technical success rate, safety profile, complication rate and efficacy of cryoablation procedures being performed in children.

This study intends to evaluate the efficacy and safety of cryoablation combined with Cardonilizumab and Bevacizumab in hepatocellular carcinoma with pulmonary metastases.
