DSA was employed using continuous intraarterial infusion tubes for various malignancies (73 cases) which were examined a total of 135 times. In head and neck malignancy (50 cases), the general position of the infusion tube had been determined beforehand by dye infusion, but DSA from the tube showed that the tubes in 24 cases (48%) were located in the wrong position, especially in tongue cancer (21 cases) where many tubes were discovered to be in an erroneous position (71%) such as the common carotid artery. We were unable to determine the effect of chemotherapy and radiation using DSA only. In 9 cases of breast cancer for which fixation of the tube was not attempted under X-ray fluoroscopy, 7 (78%) showed an unusual tube position such as the intraaortic arch. In 5 cases of abdominal malignancy, only the tube position for sigmoid colon cancer was unusual. We were able to observe the effect of chemotherapy by DSA in 2 cases. For DSA in one out of 3 hepatomas using a Port-A-Cath, we observed that infusion of anticancer drug with degradable starch microspheres caused a reduction in tumor size. However, in the two remaining cases, we were unable to observe any effect of infusion of these drugs by DSA for various mechanical reasons. DSA from an infusion tube revealed not only the location of the tube accurately and promptly, but also the effect of chemotherapy.
采用持续动脉内输注管对73例各种恶性肿瘤患者进行数字减影血管造影（DSA）检查，共检查135次。在头颈部恶性肿瘤（50例）中，输注管的大致位置已通过染料注入预先确定，但通过该管进行的DSA显示，24例（48%）的管子位置错误，尤其是在舌癌（21例）中，发现许多管子处于错误位置（71%），如颈总动脉。仅使用DSA我们无法确定化疗和放疗的效果。在9例未在X线透视下尝试固定管子的乳腺癌患者中，7例（78%）显示管子位置异常，如主动脉弓内。在5例腹部恶性肿瘤中，只有乙状结肠癌的管子位置异常。我们通过DSA在2例患者中观察到了化疗效果。在3例肝癌中的1例使用植入式静脉输液港进行DSA时，我们观察到用可降解淀粉微球输注抗癌药物导致肿瘤大小缩小。然而，在其余2例中，由于各种机械原因，我们无法通过DSA观察到这些药物输注的任何效果。通过输注管进行的DSA不仅能准确、迅速地显示管子的位置，还能显示化疗效果。
