To evaluate various types of right ventricular outflow tract obstruction associated with tetralogy of Fallot (TOF) with emphasis on the abnormality of pulmonary arterial system and other associated cardiovascular anomalies using computed tomography (CT) angiography.
We retrospectively evaluated 184 consecutive previously diagnosed TOF patients who underwent CT angiography in our department.
Infundibular with pulmonary valvular stenosis was the most common type of stenosis (47.28%) found, followed by isolated infundibular stenosis (34.23%). Isolated abnormality of both right and left pulmonary arteries was also noted. Right side aortic arch (23.91%) was the most common associated abnormality followed by double superior vena cava (9.78%).
TOF is associated with various types of right ventricular outflow tract obstruction ranging from infundibular narrowing to isolated narrowing of right or left pulmonary arteries and is also associated with various other congenital abnormalities of the cardiovascular system. CT angiography is an excellent imaging modality, which provides comprehensive analysis of various abnormalities associated with TOF.
利用计算机断层扫描（CT）血管造影术评估与法洛四联症（TOF）相关的各类右心室流出道梗阻，重点关注肺动脉系统异常及其他相关心血管畸形。
我们回顾性评估了在我科接受CT血管造影术的184例先前确诊的TOF患者。
漏斗部合并肺动脉瓣狭窄是最常见的狭窄类型（47.28%），其次是单纯漏斗部狭窄（34.23%）。还发现了左右肺动脉的孤立性异常。右侧主动脉弓（23.91%）是最常见的相关异常，其次是双上腔静脉（9.78%）。
TOF与各类右心室流出道梗阻相关，范围从漏斗部狭窄到右或左肺动脉的孤立性狭窄，还与心血管系统的各种其他先天性异常相关。CT血管造影术是一种出色的成像方式，可对与TOF相关的各种异常进行全面分析。
