Coarctation of the descending aorta, patent ductus arteriosus, deficiency of right superior vena cava, and persistent left superior vena cava in a five-month infant demonstrated by multislice computed tomography

Abstract 

A 5‐month‐old female presented in our hospital with cyanosis, peripheral psychroesthesia, and signifacantly lower blood pressure of lower limbs compared with the upper limbs; suggesting aortic coarctation. The presence of patent ductus arteriosus (PDA) and persistent left superior vena cava (PLSVC) was suspected by echocardiogram. Before surgery, we performed multislice computed tomography to determine the spatial relationship between the site of aortic coarctation, PDA, and PLSVC. Although contrast material was injected from the right cubital vein, PLSVC was exclusively enhaced; therefore, deficiency of right superior vena cava was diagnosed. Coarctation of the DAo was observed in the right posterior direction of PLSVC and PDA was observed just distal to the coarctation site of the DAo and located at the right posterior direction of PLSVC. Therefore, the spatial relationship of PLSVC, coarctation of DAo and PDA could be evalutaed and a direct anastomosis of the DAo and ligation of PDA were performed.
