82 patients were examined by IA-DSA using 4-F-catheter, 70 on an hospital and 12 on an outpatient basis. The examination included imaging of the aortic arch and selective depiction of both carotid arteries and required 30 ml of contrast agent for these three consecutive series. Image quality was evaluated for each vessel respectively. Cerebrovascular insufficiency could be diagnosed with the same accuracy as in conventional angiography. A definite diagnosis could be made in 96% of the cases for the right and in 98% for the left carotid artery. The vertebral arteries posed more problems for evaluation and required additional imaging depending on the clinical situation. Since introduction of IA-DSA the procedure seems to be less hazardous compared with conventional angiography because less contrast agent is needed and smaller catheters can be used.
82例患者接受了使用4F导管的IA-DSA检查，其中70例在医院进行，12例在门诊进行。检查包括主动脉弓成像以及双侧颈动脉的选择性显影，这三个连续系列需要30毫升造影剂。分别对每个血管的图像质量进行评估。脑血管供血不足的诊断准确性与传统血管造影相同。右侧颈动脉96%的病例和左侧颈动脉98%的病例可做出明确诊断。椎动脉的评估存在更多问题，需要根据临床情况进行额外成像。自引入IA-DSA以来，与传统血管造影相比，该检查似乎危险性更小，因为所需造影剂更少且可使用更细的导管。
