摘要
目的探讨高压注射器在全身不同部位的血管检查与治疗时的技术参数,以提高影像质量。方法对2009年7月-2010年9月使用高压注射器进行不同部位的血管检查与治疗692例进行回顾性分析,造影部位肝血管341例,脑血管71例,胸部大血管19例,四肢血管203例。结果以被检查部位血管充盈良好、对比剂无反流、各时相显影清晰、符合诊疗要求为标准,对造影图像进行评价,符合要求615例,占88.7%;血管充盈欠佳、对比剂无反流62例,占9%;血管显示不良,产生反流的9例,占1.3%;注射过程中患者造影部位活动导致血管显示不良6例,占0.8%。所有病例在检查过程中无意外发生。结论根据不同部位血管的特点,使用的导管类型、设备性能和血管病变的性质,合理选择一定的注射参数,能使所检查的血管显示良好,为血管检查与治疗提供可靠的影像资料。
Objective To explore the optimal parameters of high pressure injector in performing interventional angiography and therapy of different parts of body in order to improve the image quality. Methods During the period from July 2009 to September 2010 interventional angiography or therapy of different parts of body with the help of high pressure injector was performed in 692 patients, including 538 males and 154 females with a mean age of (53.6 + 2.5) years. The clinical data were retrospectively analyzed. The angiographic regions included hepatic vessels (n = 341 ), cerebral vessels (n = 71 ), thoracic larger vessels (n = 19) and the vessels of the arms and legs (n = 203). The technical parameters and the image qualities were evaluated and analyzed. Results Based on the contrast filling degree, the presence or absence of contrast reflux, the imaging resolution and the satisfactory degree in meeting the diagnostic requirements, the angiographic images were evaluated. The image quality was up to standard in 615 eases (88.7%). Unsatisfactory contrast filling with no contrast reflux was seen in 62 cases (9.0%), and poor vascular opacification with contrast reflux was found in 9 cases (1.3%). Vagueness of the images caused by the body movement during exposure was seen in 6 cases (0.8%). No accidental events occurred in all procedures. Conclusion The use of appropriate catheter, equipment and reasonable injecting parameters, which can match the characteristics of the target lesions, is the key to provide physicians with reliable angiography images.
