Abstract

CT angiography might be a suitable procedure to avoid arterial puncture in combined intracavitary and interstitial brachytherapy for cervical cancer curatively treated with combined chemoradiation and brachytherapy boost. Data in the literature about this technique are scarce. We introduced this method and collected brachytherapy data from patients treated in our department between May 2021 and April 2024. We analyzed the applicator subtype, needle insertion (planned versus implanted), implanted depth and the role of CT angiography in selecting needle trajectories and insertion depths. None of the patients managed through this protocol experienced atrial puncture and consequent hemorrhage. Needle positions were accurately selected with the aid of CT angiography with proper coverage of brachytherapy targets and avoidance of organs at risk. CT angiography is a promising method for guiding needle insertion during interstitial brachytherapy.

摘要

在同步放化疗联合近距离放疗根治性治疗宫颈癌的腔内和组织间联合近距离放疗中，CT血管造影可能是一种避免动脉穿刺的合适方法。关于该技术的文献数据稀缺。我们引入了这种方法，并收集了2021年5月至2024年4月在我科接受治疗的患者的近距离放疗数据。我们分析了施源器亚型、针插入情况（计划与植入）、植入深度以及CT血管造影在选择针轨迹和插入深度中的作用。通过该方案治疗的患者均未发生动脉穿刺及随之而来的出血。借助CT血管造影准确选择了针的位置，适当地覆盖了近距离放疗靶区并避免了危及器官。CT血管造影是组织间近距离放疗期间引导针插入的一种有前景的方法。
