目的 探讨介入放射学在结直肠癌诊治中的价值。方法 ４９ 例结直肠癌患者分别用ＤＳＡ 法进行了选择性动脉造影和区域化疗，对１ 例晚期直肠癌患者和１ 例直肠癌术后肝转移患者，留置了化疗泵（ＰＣＳ） 。结果 所有结直肠癌病灶在动脉造影时均明确显示，与手术符合率１００％ 。７ 例有不同程度肠梗阻的直肠癌患者，经动脉区域化疗后，６ 例症状得到改善。所有病例均无与插管有关的并发症。结论 介入放射学为结直肠癌的诊治提供了一条新的途径。
Objective To explore the value of interventional radiology in the diagnosis and treatment of colorectal cancer. Methods Selective arterial angiography and regional chemotherapy were performed in 49 patients with colorectal cancer by DSA. Chemotherapy pumps (PCS) were reserved for 1 patient with advanced rectal cancer and 1 patient with rectal cancer after liver metastasis. Results All colorectal cancer lesions were clearly shown in the arteriography. The coincidence rate with the surgery was 100%. In 7 patients with rectal cancer with varying degrees of intestinal obstruction, 6 cases of symptoms improved after transarterial chemotherapy. There were no complications associated with intubation in all cases. Conclusion Interventional radiology provides a new way for the diagnosis and treatment of colorectal cancer.
