Abstract

Introduction: We aimed to evaluate the effect of transcatheter arterial embolization (TAE) with iodized oil (Lipiodol) on temperature change during cryoablation (CA) for renal cell carcinoma (RCC).

Material and methods: We retrospectively reviewed patients receiving CA for RCC from February 2020 to July 2021, including those who received Lipiodol TAE prior to CA (TAE group) and those who underwent only CA with comparable clinical and tumor characteristics (non-TAE group). Clinical data and tumor characteristics of both groups were recorded. The temperature readings of each cryoprobe at every 15 s and 'time to -100 °C' were compared between the groups.

Results: A total of 17 patients with 18 RCCs were recruited (seven in the TAE group and 11 in the non-TAE group). The 'time to -100 °C' was significantly longer in the TAE group than in the non-TAE group (64.5 ± 24.3 s vs. 48.8 ± 9.7 s, p = 0.018). Positive correlation between 'time to -100 °C' and tumor maximal diameter, RENAL nephrometry and PADUA score were observed in the non-TAE group, while no corresponding correlation was found in the TAE group.

Conclusions: Pre-embolization with iodized oil influences the temporal temperature changes during cryoablation by disrupting the positive correlation between the time to reach the target temperature and tumor characteristics.

碘化油栓塞对肾细胞癌冷冻消融过程中温度变化的影响

简介：我们旨在评估碘化油（Lipiodol）经导管动脉栓塞（TAE）对肾细胞癌（RCC）冷冻消融（CA）过程中温度变化的影响：我们回顾性研究了2020年2月至2021年7月期间接受CA治疗的RCC患者，包括在接受CA治疗前接受碘油TAE治疗的患者（TAE组）和仅接受CA治疗且临床和肿瘤特征相当的患者（非TAE组）。记录两组患者的临床数据和肿瘤特征。比较各组每 15 秒的每个冷冻探针的温度读数和 "达到-100 °C的时间"：结果：共招募了17名患有18颗RCC的患者（TAE组7人，非TAE组11人）。TAE 组的 "至 -100 °C 的时间 "明显长于非 TAE 组（64.5 ± 24.3 秒 vs. 48.8 ± 9.7 秒，p = 0.018）。在非TAE组中，"至-100 °C的时间 "与肿瘤最大直径、RENAL肾功能和PADUA评分呈正相关，而在TAE组中则没有发现相应的相关性：结论：碘化油预栓塞会影响低温消融过程中的时间温度变化，破坏达到目标温度的时间与肿瘤特征之间的正相关性。

期刊介绍： Minimally Invasive Therapy and Allied Technologies (MITAT) is an international forum for endoscopic surgeons, interventional radiologists and industrial instrument manufacturers. It is the official journal of the Society for Medical Innovation and Technology (SMIT) whose membership includes representatives from a broad spectrum of medical specialities, instrument manufacturing and research. The journal brings the latest developments and innovations in minimally invasive therapy to its readers. What makes Minimally Invasive Therapy and Allied Technologies unique is that we publish one or two special issues each year, which are devoted to a specific theme. Key topics covered by the journal include: interventional radiology, endoscopic surgery, imaging technology, manipulators and robotics for surgery and education and training for MIS.
