Two cases of scimitar variant.

The scimitar sign is characteristic of partial anomalous pulmonary venous drainage into the inferior vena cava (IVC). We encountered two variant cases of scimitar sign. In one case, the scimitar vein entered both the IVC and the left atrium (LA) without any intracardiac shunts. Surgical repair was made by simple ligation of the scimitar vein to correct 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 without any connection with the IVC, and surgical intervention was not required.[1]
