摘要:
目的 探討T1 SPACE技術(shù)診斷Cockett綜合征的臨床應(yīng)用價(jià)值。方法 收集我院患有慢性下肢靜脈疾病且臨床考慮Cockett綜合征的患者96例,在行數(shù)字減影血管造影檢查前2 d內(nèi)行非增強(qiáng)磁共振血管檢查。在T1 SPACE序列上測(cè)量患側(cè)髂總靜脈受壓狹窄處前后徑和健側(cè)髂總靜脈遠(yuǎn)端分叉處前后徑,并計(jì)算出狹窄率,觀察盆腔內(nèi)側(cè)支血管顯影情況。以數(shù)字減影血管造影檢查結(jié)果為金標(biāo)準(zhǔn),計(jì)算最大約登指數(shù)下對(duì)應(yīng)的狹窄率,采用ROC曲線評(píng)估最大約登指數(shù)下單獨(dú)運(yùn)用髂總靜脈狹窄率及狹窄率聯(lián)合側(cè)支血管對(duì)Cockett綜合征的診斷效能。結(jié)果 在T1 SPACE圖像上髂總靜脈平均狹窄率為(47.77±21.16)% 。以狹窄率作為診斷Cockett綜合征的標(biāo)準(zhǔn),ROC曲線下面積為 0.738,取最大約登指數(shù)對(duì)應(yīng)狹窄率43.85% 作為診斷截點(diǎn),敏感性為63.90%,特異性為83.30%,診斷符合率為68.75%; 以髂靜脈狹窄率≥43.85%聯(lián)合側(cè)支血管顯像作為診斷標(biāo)準(zhǔn),ROC曲線下面積為0.867,敏感性為 90.10%,特異性為 83.30%,診斷符合率 87.50%,兩者差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論 在T1 SPACE技術(shù)檢查中,髂靜脈受壓狹窄率對(duì)Cockett綜合征有較好的診斷效能,狹窄率聯(lián)合側(cè)支血管能進(jìn)一步提高磁共振對(duì)Cockett綜合征的診斷效能,T1 SPACE技術(shù)具有較好的臨床應(yīng)用價(jià)值。
Abstract:
Objective To explore the clinical value of T1 SPACE technique in the diagnosis of Cockett syndrome.Methods Clinical data of 96 patients with chronic lower extremity venous disease and clinically suspected Cockett syndrome in our hospital who underwent non-contrast magnetic resonance angiography within 2 days before digital subtraction angiography were collected.The anteroposterior diameter of the compressed stenosis of the ipsilateral common iliac vein and the anteroposterior diameter of the distal bifurcation of the unaffected common iliac vein were measured on T1 SPACE sequence.The stenosis rate was calculated, and the situation of pelvic medial branch vessels was observed.The corresponding stenosis rate under the maximum Youden index was calculated by using the results of digital subtraction angiography as the gold standard.The ROC curve was used to evaluate the diagnostic efficacy of the common iliac vein stenosis rate and stenosis rate combined with collateral vessels on Cockett syndrome.Results The average stenosis rate of the common iliac vein on T1 SPACE images was(47.77±21.16)%.Taking the stenosis rate as the criterion for the diagnosis of Cockett syndrome, the area under the ROC curve was 0.738.The stenosis rate was 43.85% corresponding to the maximum Youden index and it was taken as the diagnostic cut-off point.The sensitivity was 63.90%, the specificity was 83.30%, and the diagnostic coincidence rate was 68.75%.Taking the iliac vein stenosis rate ≥43.85% combined with collateral vessel imaging as the diagnostic criteria, the area under the ROC curve was 0.867, the sensitivity was 90.10%, the specificity was 83.30%, and the diagnostic coincidence rate was 87.50%.The difference between the two methods was statistically significant(P<0.05).Conclusion The iliac vein compression stenosis rate has a good efficiency in the diagnosis of Cockett syndrome, and the stenosis rate combined with collateral vessels can further improve the diagnostic efficiency with T1 SPACE technique, T1 SPACE technique has good clinical value.
