摘要
目的比较血管造影跟踪法(BCA)与传统DSA的技术特点。方法回顾性分析我院61例全下肢动脉血管造影患者的造影技术参数,其中31例采用BCA,30例采用DSA血管造影技术。分别对完成造影时间、对比剂用量、图像质量、患者吸收辐射剂量(DAP)进行对照分析。结果应用两种技术分别成功完成全下肢动脉血管造影。DSA在膝至足背血管的图像质量上优于BCA(60/65 vs 52/62),但是DAP大[(134.67±1.34)Gycm2vs(69.55±0.74)Gycm2],对比剂用量多[(94.58±1.44)ml vs(46.77±0.94)ml],检查时间长[(47.17±0.56)s vs(32.55±0.28)s]。经统计学处理,差异均具有显著性(P<0.00)。结论BCA与DSA相比具有造影时间短,对比剂量用量少,DAP低的特点,DSA局部观察血管情况较细致。因此,先行BCA筛查,然后针对病变加作局部DSA。
Objective To compare the techniques of bolus chasing angiography （BCA） and digital subtraction angiography （DSA）. Methods Sixty-one patients with symptomatic atherosclerotic peripheral disease were randomly assigned to have their lower limbs examined by BCA or DSA. Time of examination, dose of contrast medium, dose-area product （DAP） were measured. Image quality was assessed from the laser printed images by two professors. Results Examination was performed successfully by the two methods. DSA produced better images of the infrainguinal vessels （59/60 vs 52/ 62）, but at a high DAP （[134.67±1. 341 Gycm^2 vs [69.55±0. 741 Gycm^2 ）. Contrast medium dose was higher with DSA （[94.58±1. 441 ml vs [46.77±0. 941 ml）. Times was higher with DSA than BCA （[47.17±0. 561 s vs [32.55±0. 281 s）. Statistically significant difference was showed （P〈0.001）. Image quality evaluation of iliac, femoral and popliteal vessels was no statistically difference （P〉0.05）. Conclusion BCA is the most effective way which required more technical skill. We suggest that BCA be used as the first choice and be complemented by DSA while local pathological change is detected.
