摘　　要：目的 :了解MRA在颈动脉外科的应用价值。方法 :对本院头颈科1997年8月～1999年5月间收治的涉及颈动脉疾病患者9例中6例 ,进行了术前MRA检测 ,其中2例实施术后分析检测。结果 :颈动脉体瘤、颈动脉瘤及某些颈部转移肿瘤累及颈动脉的MRA表现与血管造影相似 ;MRA可直接显示颈动脉分歧部切除术后脑血管侧支循环血管影像。结论 :MRA作为一非创伤性血管显影新技术 ,可用于颈部肿瘤累及颈动脉或颈动脉本身疾病的术前诊断和术后脑代偿供血分析研究 ,值得推荐。Objective: To assess the possibility of application of MRA in carotid surgery. Methods: MRA was performed in 6 patients with carotid diseases. Results: MRA can be used in the diagnosis of carotid body tumor, carotid aneurysm and metastatic carcinoma invasion of carotid artery as well as in assessing the collateral cerebral crossflow after carotid artery resection. Conclusion: MRA is a recently developed noninvasive vascular technique without contrast agents. MRA is safer and more practical than traditional angiography. Although the use of MRA has some limitation but its role continues to expand. The value of MRA for diagnosis and treatment planning is paramount. The authors recommend more frequent use of this imaging technique in the practice of carotid surgery.
