Pressure wire was used to measure trans-stenosis pressure difference (\u0394P). Digital subtraction angiography, Transcranial Doppler and Electronic sphygmomanometer were introduced to assess stenotic rate, steal grade and inter-arm systolic pressure difference, respectively. Clinical symptoms and restenosis were followed up after endovascular therapy. The associations of \u0394P with stenotic rate, inter-arm pressure difference, steal degree, clinic symptoms and restenosis were analyzed in this paper.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Prior to the therapy, \u0394P moderately correlated with stenotic rate (r\u2009=\u20090.757, p\u2009=\u20090.007) and inter-arm pressure difference (r\u2009=\u20090.701, p\u2009=\u20090.016). \u0394P was \u22656\u2009mmHg in all patients, and 6\u20139\u2009mmHg for grade 1 steal and \u226510\u2009mmHg for grade 2 and 3 steals. After the therapy, all patients had technique success, and 10 patients had clinic success, and 1 patient appeared restenosis. \u0394P was \u22643\u2009mmHg and steal disappeared in the patients with clinical success. \u0394P was 18\u2009mmHg and grade 3 steal still existed in one patient without clinical success. One patient with 1\u2009mmHg of \u0394P after therapy appeared restenosis in the follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The trans-stenosis pressure difference is closely related to steal degree and clinical symptoms. The measurement of hemodynamic status by pressure wire is very useful to guide endovascular therapy in subclavian steal syndrome patients. However, the restenosis may still occur, even though the hemodynamic impairment is improved.<\/jats:p>\n
