目的 探讨放疗所致动脉损伤的血管造影表现及评价该病的血管造影的价值。 方法 分析 14例患者经血管造影证实为放疗后动脉损伤的影像学资料。 结果 14例动脉损伤的病变中， 10例为动脉狭窄、 3例为动脉闭塞、 1例为动脉瘤。病变位于髂动脉 5例，锁骨下动脉 4例，肾动脉 2例，肠系膜上动脉 3例。血管造影和超声检查显示所有患者的动脉损伤均位于放疗野内。 结论 血管造影可显示动脉损伤的范围，同时还为介入放射治疗提供入路。
Objective To investigate the angiographic findings of arterial injury caused by radiotherapy and the value of angiography in evaluating the disease. Methods The imaging data of 14 patients who were confirmed by angiography as arterial injury after radiotherapy were analyzed. Results Of the 14 cases of arterial injury, 10 had arterial stenosis, 3 had arterial occlusion, and 1 had aneurysm. The lesions were located in 5 cases of iliac artery, 4 cases of subclavian artery, 2 cases of renal artery, 3 cases of superior mesenteric artery. Angiography and sonography showed that all patients had arterial lesions in the radiotherapy field. Conclusions Angiography shows the extent of arterial injury and also provides a route of interventional radiotherapy.
