本文报告了３２００例脑血管数字减影血管造影（ＤＳＡ）的临床应用经验。本组病例中静脉法ＤＳＡ（ＩＶＤＳＡ）为２９８６例，动脉法ＤＳＡ（ＩＡＤＳＡ）２１４例。共查出１８病种，临床符合率为９２．８％，手术符合率为９８．２％。与常规动脉造影相比，ＩＶＤＳＡ操作简便，安全易行，无并发症，基本上可取代常规血管造影。ＩＡＤＳＡ影像分辨力高，对小血管的观察满意，由于实时显像，造影剂用量仅为常规血管造影的２０～３０％，对多种脑血管疾病有较高的诊断价值，对颅内血肿，脑肿瘤亦能作出诊断。作者认为ＩＶＤＳＡ是脑血管疾病的首选检查方法。
This article reports on 3200 clinical trials of cerebrovascular digital subtraction angiography (DSA). The group of patients with intravenous DSA (IVDSA) was 2986 cases, artery DSA (IADSA) 214 cases. A total of 18 kinds of diseases were found, the clinical compliance rate was 92.8%, the coincidence rate was 98.2%. Compared with conventional arteriography, IVDSA is easy to operate, safe and easy to operate without complications, and can basically replace conventional angiography. IADSA image resolution, the satisfaction of the observation of small vessels, due to real-time imaging, contrast agent dosage is only 20 to 30% of conventional angiography, a variety of cerebrovascular diseases have a higher diagnostic value of intracranial hematoma, Brain tumors can also make a diagnosis. The authors believe that IVDSA is the preferred method of detection of cerebrovascular disease.
