摘　　要：目的探讨旋转DSA技术在头颈部血管成像中的应用。方法使用SIEMENS AXIOM ArtisdTA大平板数字减影血管造影系统,对疑有头颈部血管病变的39例患者全部行常规正侧位DSA检查,对其中21例又行旋转DSA检查,研究其技术参数,并评价其应用价值。结果39例患者检出头颈部血管病变34例,其中,颅内动脉瘤17例,动脉狭窄9例,动静脉畸形4例,颈动脉海绵窦瘘2例和脑膜瘤2例。经旋转DSA的21例患者,病变血管的形态、位置及毗邻关系较常规DSA更清楚显示。结论常规DSA是诊断头颈部血管性疾病的必要检查方法,旋转DSA能够清楚显示头颈病变血管的供血动脉和分支结构,对头颈部血管性疾病的诊断、治疗及复查有重要的应用价值。Objective To explore the application of rotational digital subtraction angiography（RDSA）in cephalocervical angiography. Methods Thirty-nine patients with clinically suspected encephalocervical angiopathy underwent the conventional DSA（SIEMENS AXIOM Artis dTA DSA system）, of them , 21 patients underwent additional RDSA（SIEMENS AXIOM Artis dTA DSA system）. The techni- cal parameter and application value during DSA were analyzed and assessed. Results Among 39 cases, encephalocervical angiopaths were found in 34 cases who comprised 17 intracranial aneurysms, 9 arteriostenoses, 4 arteriovenous malformations, 2 carotid cavernous fistulae, and 2 meningiomas. The appearance, location and adjacent relationship of the lesions in 21 patients who underwent RDSA were more clearly displayed than conventional DSA. Conclusion In the diagnosis of encephalocervical angiopath, coventional DSA is necessary means, while RDSA can more clealy display the blood supplying arteries and branch structures of encephalocervical angiopath so that it has important value in the diagnosis, treatment and reexamination of this disease.
