【摘要】：目的探討多層螺旋CT血管成像(MSCTA)在先天性肝內(nèi)門-體靜脈分流(CIPSVS)診斷中的價(jià)值。方法搜集經(jīng)篩查后確診的29例CIPSVS患者,由2名放射科醫(yī)師采用盲法對(duì)其MSCT常規(guī)成像(平掃及增強(qiáng))和MSCTA重組(MPR、MIP、VR)的圖像共同閱片,分析CIPSVS的MSCTA特征,分別統(tǒng)計(jì)和比較兩種技術(shù)對(duì)CIPSVS的發(fā)現(xiàn)率、漏診率、診斷正確率,并采用配對(duì)資料χ2檢驗(yàn)。結(jié)果 29例患者中,病灶分流局部情況:2例通過側(cè)側(cè)相貼吻合,6例通過短或長(zhǎng)管狀血管吻合,21例通過大小不一結(jié)節(jié)狀或不規(guī)則形靜脈瘤吻合分流,其中14個(gè)交通靜脈瘤瘤體直徑2 cm,7個(gè)瘤體直徑≥2 cm。對(duì)CIPSVS的發(fā)現(xiàn)率、漏診率、診斷正確率在常規(guī)的平掃及增強(qiáng)成像為93.1%(27/29)、6.9%(2/29)、75.9%(22/29);在MSCTA重組為100%(29/29)、0%(0/29)、100%(29/29),兩者間的發(fā)現(xiàn)率和漏診率差異無統(tǒng)計(jì)學(xué)意義(χ2=0.518、0.518,P=0.472、0.472);正確率差異有統(tǒng)計(jì)學(xué)意義(χ2=5.849,P=0.016)。結(jié)論 MSCTA能清晰、直觀地顯示CIPSVS的分流病灶及供血引流靜脈,對(duì)診斷CIPSVS、判斷其分型具有較高的應(yīng)用價(jià)值。
[Abstract]:Objective to evaluate the value of multislice spiral CT angiography (MSCTA) in the diagnosis of congenital intrahepatic portal-systemic shunt (CIPSVS). Methods A total of 29 patients with CIPSVS diagnosed after screening were collected. The MSCTA features of CIPSVS were analyzed by two radiologists. The images of MSCT routine imaging (plain scan and enhancement) and MSCTA recombination (MPR,MIP,VR) were read together by two radiologists. The detection rate, missed diagnosis rate and correct diagnosis rate of CIPSVS were statistically analyzed and compared. The paired data 蠂 2 test was used. Results among 29 patients, the focal shunt was found in 2 cases by lateral anastomosis, 6 cases by short or long vessel anastomosis, and 21 cases by nodular or irregular venous aneurysm of different size. Of these, 14 had tumor diameters of 2 cm, and 7 with diameters 鈮，
