目的 :探讨血管跟踪造影技术检查下肢血管性病变的方法和效果。方法 :通过造影床的两次移动 ,先摄取未注射对比剂的下肢影像 ,再摄取注射后的血管图像 ,两者相减 ,得到整个肢体连续的血管减影图像。结果 :12例患者行 16例次跟踪造影均获得成功 ,11例发现病变 ,其中 9例下肢血管广泛性存在动脉粥样硬化 ,伴不同程度的狭窄 ;2例患者血管完全闭塞 ,其中 1例行经导管血栓旋切术后再通 ,另 1例溶栓治疗后 ,行PTA球囊扩张并置入血管内支架 1枚。结论 :利用跟踪造影技术检查下肢血管性病变 ,操作简单 ,患者痛苦小 ,病灶部位显示清楚。
Objective: To investigate the method and effect of vascular tracking angiography in detecting lower extremity vascular lesions. Methods: After moving the contrast bed twice, the images of the lower extremities of the uninjected contrast medium were taken first, then the images of the injected blood vessels were taken, and the two images were subtracted to obtain the continuous angio subtraction images of the entire limbs. Results: Twelve patients were successful in follow-up imaging of 16 cases, and 11 cases were found to be pathological changes. Among them, 9 cases had extensive vascular atherosclerosis in the lower extremities with varying degrees of stenosis. Two patients had complete occlusion of blood vessels, of which 1 was performed Transcatheter thrombectomy after revascularization, the other 1 cases of thrombolytic therapy, line PTA balloon dilatation and placement of a stent. Conclusion: The use of follow-up angiography to detect lower extremity vascular lesions, simple operation, patients with small pain, the lesion showed clearly.
