CT-guided paravertebral block for microwave ablation of kidney tumors: a new technique

摘要

Patients suffering from renal carcinoma classified T1a and considered to be poor candidates for surgery were included in this prospective, single-center pilot study. They underwent MWA under CT-guided loco-regional anesthesia: an anterior variant of the PVB at the level of T10, ipsilateral to the renal MWA associated with anesthesia of the kidney capsule and EMONO. Technical success was defined as total thermal ablation without additional sedation and no side effect during the procedure. Maximal pain score during the procedure was assessed using a visual analog score.
