CT-guided robotic-assisted percutaneous interventions: first experience

Abstract

Computed tomography is an effective method of monitoring of percutaneous interventions. Conventional CT guidance and CT-fluoroscopy are used most frequently for proce dure monitoring. Image-guided robotic needle positioning is an alternative and relatively modern approach for interventional procedures. Purpose: to demonstrate convenience, effectiveness and safety of robotic system for CT-guided interventions. Materials and methods. CT-guided percutaneous interventions were performed in FSBI “N.N. Petrov NMRC of Oncology” Ministry of Healthcare of The Russian Federation using the Philips Ingenuity CT scanner and Maxio Perfint robotic system. This article presents clinical observations of adrenal tumor biopsy and cryoablation of a renal cell carcinoma. For cryoablation the Medical Cryotherapeutic System was used. Results. The robotic system for CT-guided interventions allowed to perform corresponding surgical procedures. Conclusions. The Maxio robotic console seems to be a promising technical solution for CT-guided interventions. Evaluation of the effectiveness of the robotic and traditional approaches of CT control in percutaneous procedures requires further investigations and analysis on larger data sample in longer periods of observation.
