Measurement of Intrahepatic Pressure during Microwave Ablation in an Ex Vivo Bovine Liver Model
BACKGROUND/AIMS We experimented with different ablation methods and two types of microwave antennas to determine whether microwave ablation (MWA) increases intrahepatic pressure and to identify an MWA protocol that avoids increasing intrahepatic pressure. METHODS MWA was performed using either a single-step standard ablation or a stepwise increment ablation paired with either a 16-gauge (G) 2...
متن کاملComparison of Wet Radiofrequency Ablation with Dry Radiofrequency Ablation and Radiofrequency Ablation Using Hypertonic Saline Preinjection: Ex Vivo Bovine Liver
OBJECTIVE We wished to compare the in-vitro efficiency of wet radiofrequency(RF) ablation with the efficiency of dry RF ablation and RF ablation with preinjection of NaCl solutions using excised bovine liver. MATERIALS AND METHODS Radiofrequency was applied to excised bovine livers in a monopolar mode for 10 minutes using a 200 W generator and a perfused-cooled electrode with or without injec...
متن کاملEnhanced Percutaneous Permeation After Fractional Thermo-Ablation: an Ex Vivo Study
Background: Thermo mechanical ablation (TMA) is a novel platform for fractional ablation and non-ablation for skin treatment with no pain. Objective: This study aimed to evaluate the effects of TMA pre-treatment to facilitate transdermal drug delivery. Methods: Novoxel’s proprietary Tixel ® TMA system was evaluated in this study by a diffusion cell system using excised porcine ear skin. A 1 cm ...
متن کاملFluid-modulated bipolar radiofrequency ablation: an ex-vivo evaluation study.
BACKGROUND The effect of radiofrequency ablation (RFA) can be modulated by fluid injection. PURPOSE To evaluate the potential of different fluids to modulate the effect of bipolar RFA in an ex-vivo liver model. MATERIAL AND METHODS A bipolar RFA system with an internally cooled needle-shaped applicator (20-mm active tip) was used to induce coagulation lesions in ex-vivo porcine liver. Prior...
متن کاملFluid preinjection for microwave ablation in an ex vivo bovine liver model assessed with volumetry in an open MRI system.
PURPOSE We aimed to detect possible differences in microwave ablation (MWA) volumes after different fluid preinjections using magnetic resonance imaging (MRI). MATERIALS AND METHODS MWA volumes were created in 50 cuboid ex vivo bovine liver specimens (five series: control [no injection], 10 mL water, 10 mL 0.9% NaCl, 10 mL 6% NaCl, and 10 mL 12% NaCl preinjections; n=10 for each series). The ...
