The Clinical Study of the Persistent Left Superior Vena Cava
|
|

Abstract
|
|
|
We have encountered persistent left superior vena cava in 43 of 1362 patients referred for investigation or operation of congenital heart lesions.
Data from clinical, roentgenologic and catheterization studies on forty three patients with this anomaly are presented.
1. The incidence of this anomaly in a series of patients investigated for suspected congenital heart disease, was 3.2 percent.
2. Among 43 cases, 23 were male and 20 were female.
3. In thirty nine of our patients the left superior vena cava was discovered during catheterization or angiography. In one, it was found at autopsy and in the remaining three patients its presence was demonstrated at operation.
4. Thirty patients had cyanotic congenital heart disease.
5. Tetralogy of Fallot was the most frequent cardiac anomaly associated with left superior vena cava (one-third; 13 cases) 9 patients has extracardiac anomalies.
6. In 39 patients the left superior vena cava entered the coronary sinus, which in turn communicated with right atrium, and in one patient it entered the left atrium directly, but in the remaining three patients its enterance was undetermined due to severe complex intracardiac anomalies.
7. Reviewing the posteroanterior chest roentgenograms of patients with left superior vena cava, we observed a crescentic vascular shadow passing from. the upper left border of the aortic arch toward the middle third of the clavicle in eighteen among 33 patients.
