Analytical transient-time solution for temperature in non perfused tissue during radiofrequency ablation

López Molina, Juan Antonio; Rivera Ortun, María José; Berjano Zanón, Enrique (Elsevier, 2016-10-26)

[EN] Radiofrequency ablation (RFA) with internally cooled needle-like electrodes is a technique widely used to destroy cancer cells. In a previous study we obtained the analytical solution of the biological heat equation ...
Comparison of two radiofrequency-based hemostatic devices: saline-linked bipolar vs. cooled-electrode monopolar

Moll, Xavier; Fondevila, Dolors; García-Arnás, Félix; Burdio, Fernando; Trujillo Guillen, Macarena; Irastorza, Ramiro M.; Berjano, Enrique; Andaluz, Anna (Taylor & Francis, 2022-12-31)

[EN] Purpose To characterize the coagulation zones created by two radiofrequency (RF)-based hemostatic devices: one comprised an internally cooled monopolar electrode and the other comprised externally irrigated bipolar ...
Computer modeling of an impedance-controlled pulsing protocol for RF tumor ablation with a cooled electrode

Trujillo Guillen, Macarena; Bon Corbín, José; Rivera Ortun, María José; Burdio, Fernando; Berjano, Enrique (Taylor & Francis, 2016)

[EN] Purpose: To develop computer models to mimic the impedance-controlled pulsing protocol implemented in radiofrequency (RF) generators used for clinical practice of radiofrequency ablation (RFA), and to assess the ...
Electrical-thermal analytical modeling of monopolar RF thermal ablation of biological tissues: determining the circumstances under which tissue temperature reaches a steady state

López Molina, Juan Antonio; Rivera Ortun, María José; Berjano, Enrique (American Institute of Mathematical Sciences (AIMS), 2016-04)

[EN] It has been suggested that during RF thermal ablation of biological tissue the thermal lesion could reach an equilibrium size after 1-2 minutes. Our objective was to determine under which circumstances of electrode ...
Impact of monopolar radiofrequency coagulation on intraoperative blood loss during liver resection: a prospective randomised controlled trial

Quesada-Diez, Rita; Poves, Ignasi; Berjano, Enrique; Vilaplana, Carles; Andaluz, Anna; Moll, Xavier; Dorcaratto, Dimitri; Grande, Luís; Burdío Pinilla, Fernando (Taylor & Francis, 2017)

Purpose: To evaluate the impact of using monopolar thermal coagulation based on radiofrequency (RF) currents on intraoperative blood loss during liver resection. Materials and methods: A prospective randomized controlled ...
Relationship between roll-off occurrence and spatial distribution of dehydrated tissue during RF ablation with cooled electrodes

Trujillo Guillen, Macarena; Alba Martínez, José; Berjano, Enrique (Informa Healthcare, 2012-02)

Purpose: To study the relationship between roll-off (sudden increase in impedance) and spatial distribution of dehydrated tissue during RF ablation using a cooled electrode (temperatures around 100°C). Methods: We used ...
