目的分析主动脉弓离断(interruption of aortic arch,IAA)患者的心血管造影影像,提高对本病的认识和诊断准确性。资料与方法 8例患者均经股动脉、股静脉穿刺插管,行右心室、左心室、降主动脉造影。其中3例经右颈总动脉穿刺插管行升主动脉造影;3例从右心室经室间隔缺损至升主动脉造影。结果 8例升主动脉与降主动脉之间均无血流连续。升主动脉细小7例,升主动脉扩张1例,降主动脉顶端与未闭的动脉导管连接7例,降主动脉与右锁骨下动脉连接1例。8例均合并心内畸形,其中室间隔缺损+动脉导管未闭并肺动脉高压5例,右室双出口+动脉导管未闭并肺动脉高压2例,法乐四联症1例。结论心血管造影是IAA确诊的重要方法,能够为IAA的早期有效诊断和外科手术适应证的选择提供重要的临床依据。
Objective To analyze the angiographic images of patients with interruption of aortic arch (IAA) and to improve their understanding of the disease and the diagnostic accuracy. Materials and Methods All 8 patients underwent femoral artery and femoral vein puncture and intubation. Right ventricle, left ventricle and descending aorta were performed. Three of them were ascending aorta through the right common carotid artery and three from the right ventricle through the ventricular septal defect to the ascending aorta. Results There was no continuous blood flow between ascending aorta and descending aorta in 8 patients. Ascending aorta in 7 cases, dilatation of the ascending aorta in 1 case, descending aorta and patent ductus arteriosus in 7 cases, descending aorta and right subclavian artery in 1 case. 8 cases were complicated with intracardiac malformations, including ventricular septal defect + patent ductus arteriosus and pulmonary hypertension in 5 cases, double outlet right ventricle + patent ductus arteriosus and pulmonary hypertension in 2 cases, tetralogy of Fallot in 1 case. Conclusions Cardiovascular angiography is an important method for the diagnosis of IAA. It can provide important clinical evidence for early effective diagnosis of IAA and selection of surgical indications.
