Abstract
Objective To explore the diagnostic value of color Doppler flow imaging (CDFI), transcranial Doppler(TCD) and digital subtraction angiography(DSA) on subclavian steal syndrome (SSS). Methods Atfal of 42 patients with SSS who were admitted to our hospital from January 2013 to December 2013 were selected. They were diagnosed by CDFI, TCD and DAS respectively. Results (1)CDFI diagnostic:17 patients had moderate stenosis of subclavian artery, 15 pa-tients had severe stenosis, and 10 patients had arterial occlusion. 32 patients had atherosclerotic plaque and 7 patients had takayasu arteritis. (2)TCD diagnostic: 16 patients had phase I steal blood, 20 patients had phase II steal blood, and 6 patients had phase III steal blood. (3)DSA diagnostic: 8 patients had mild stenosis of subclavian artery, 14 pa-tients had moderate stenosis, 12 patients had severe stenosis, and 8 patients had arterial occlusion. Conclusion The above three diagnoses all have significant diagnostic value on SSS, and the above methods can be combined clinically so as to improve the accuracy of diagnosis. However, only DAS diagnosis is able to provide dynamic vascular path dia-gram of subclavian artery and geometric data for patients, and this will provide beneficial suggestions for formulating patients' surgical procedures. Therefore, if conditions are limited and combined diagnosis with three diagnostic methods cannot be carried out, the current author suggests DSA diagnosis for patients with SSS.关键词
