2 CASES OF SCIMITAR VARIANT

The scimitar sign is characteristic of partial anomalous pulmonary ven ous drainage into the inferior vena cava (IVC). We encountered two var iant cases of scimitar sign. In one case, the scimitar vein entered bo th the IVC and the left atrium (LA) without any intracardiac shunts. S urgical repair was made by simple ligation of the scimitar vein to cor rect the left to right shunt. Retrograde balloon occlusion angiography of the scimitar vein was diagnostic. In the other case, the scimitar vein showed a meandering course, and then drained into the LA withhout any connection with the IVC, and surgical intervention was not requir ed.
