To explore the diagnostic value of spatiotemporal image correlation (STIC) for different types of fetal conotruncal defects (CTDs).
The clinical data and STIC images of 174 fetuses with CTDs diagnosed via prenatal ultrasound were analyzed retrospectively.
Among the 174 cases of CTDs, 58 were tetralogy of Fallot (TOF); 30, transposition of great arteries (TGA) (D-TGA, 23 cases; cc-TGA, 7 cases); 26, double outlet of the right ventricle (DORV); 32, persistent arterial trunk (PTA) (type A1, 15 cases; type A2, 11 cases; type A3, 5 cases; type A4, 1 case); and 28, pulmonary atresia (PA) (ventricular septal defect, 24 cases; ventricular septal integrity, 4 cases). Among the cases, 156 were complicated with complex congenital intracardiac and extracardiac malformations. The abnormal display rate of the four-chamber view of two-dimensional echocardiography was low. The display rate of the permanent arterial trunk was the highest (90.6%) in STIC imaging.
STIC imaging can be used in the diagnosis of different types of CTDs, especially in persistent arterial trunks, and thus has great value for the clinical treatment and prognosis of these defects.
探索时空关联成像（STIC）对不同类型胎儿圆锥动脉干畸形（CTD）的诊断价值。
回顾性分析 174 例经产前超声诊断为 CTD 的胎儿的临床资料和 STIC 图像。
在 174 例 CTD 中，58 例为法洛四联症（TOF）；30 例为大动脉转位（TGA）（D-TGA，23 例；cc-TGA，7 例）；26 例为右心室双出口（DORV）；32 例为永存动脉干（PTA）（A1 型，15 例；A2 型，11 例；A3 型，5 例；A4 型，1 例）；28 例为肺动脉闭锁（PA）（室间隔缺损，24 例；室间隔完整，4 例）。在这些病例中，156 例伴有复杂的先天性心脏内外畸形。二维超声心动图四腔心切面的异常显示率较低。在 STIC 成像中，永存动脉干的显示率最高（90.6%）。
STIC 成像可用于不同类型 CTD 的诊断，尤其是永存动脉干，对这些缺陷的临床治疗和预后具有重要价值。
