Abstract

A 67-year-old man was referred to our hospital for the diagnosis and treatment of prostate cancer. Multidisciplinary discussion led to intensity-modulated radiotherapy preceded by hormone therapy. Before radiotherapy, a biodegradable hydrogel spacer (HS) was placed between the prostate and rectum to reduce radiation injury risk. Three weeks postplacement, pelvic magnetic resonance imaging revealed HS migration into the pelvic vein. Subsequent whole-body contrast-enhanced computed tomography (CECT) revealed HS migration into the pulmonary artery. The patient showed no symptoms or clinical signs. Radiotherapy was completed uneventfully. Complete absorption of the migrated HS was confirmed using CECT images 5 months postplacement.

一例放疗用水凝胶垫片移入肺动脉的病例。

一名 67 岁的男子因前列腺癌被转诊到我院接受诊断和治疗。经多学科讨论后，患者接受了调强放疗，并在放疗前接受了激素治疗。放疗前，在前列腺和直肠之间放置了一个生物可降解水凝胶垫片（HS），以降低放射损伤风险。放置三周后，盆腔磁共振成像显示 HS 移入盆腔静脉。随后的全身对比增强计算机断层扫描（CECT）显示，HS移入肺动脉。患者没有任何症状或临床体征。放疗顺利完成。放置后 5 个月，CECT 图像证实移位的 HS 已完全吸收。
