The ratio of TSS was calculated by dividing the cross-sectional areas of the maximal stenosed transverse sinus by that of the adjacent normal transverse sinus on CTV. The correlations among and predictive values of TSS, TPG, and ICP were analyzed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In patients with unilateral venous PT, the symptomatic-sided and average bilateral TSS values were 78 \u00b1 11 and 77 \u00b1 9%; ICP, 230.50 \u00b1 55.75 mmH\n 2<\/jats:sub>\n O; and the TPG, 9.51 \u00b1 5.76 mmHg. The symptomatic-sided TSS was linearly and positively correlated with TPG (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.400), and the symptomatic-sided and bilateral average TSS both showed weak correlations with ICP (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.288,\n R<\/jats:italic>\n \u2032\n 2<\/jats:sup>\n = 0.156). When the degree of TSS increased by 10%, the TPG and ICP increased by approximately 3.3 mmHg and 25.8 mmH\n 2<\/jats:sub>\n O, respectively. The receiver operating characteristic curve showed the optimal threshold of ipsilateral TSS for a positive TPG was 0.75, while TSS had no significant predictive value for ICP (\n p<\/jats:italic>\n &gt; 0.05). TPG and ICP also exhibited a linear positive correlation (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.552). When ICP increased by 10 mmH\n 2<\/jats:sub>\n O, the TPG increased by approximately 0.77 mmHg, and the optimal threshold of ICP for a positive TPG was 227.5.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n TSS, TPG, and ICP are interrelated. TSS measured by CTV can predict TPG in patients with unilateral venous PT.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fnins.2021.694731","type":"journal-article","created":{"date-parts":[[2021,9,4]],"date-time":"2021-09-04T04:10:31Z","timestamp":1630728631000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["The Relationships Among Transverse Sinus Stenosis Measured by CT Venography, Venous Trans-stenotic Pressure Gradient and Intracranial Pressure in Patients With Unilateral Venous Pulsatile Tinnitus"],"prefix":"10.3389","volume":"15","author":[{"given":"Xiaoyu","family":"Qiu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengfei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoshuai","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heyu","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guopeng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Long","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenghan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shusheng","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenchang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,9,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2108","DOI":"10.3174\/ajnr.A5833","article-title":"MR venous flow in sigmoid sinus diverticulum.","volume":"39","author":"Amans","year":"2018","journal-title":"AJNR Am.
