Superior vena caval (SVC) duplication is the most common form of a left-sided SVC, where the normal right-sided SVC remains. The right SVC, however, can be smaller in approximately two-thirds of such cases ³.

Epidemiology

Double SVC occurs in 0.3% of the general population. In those with congenital heart diseases, double SVC happens in 10 to 11% ⁴.

Pathology

Results from failure of the embryonic left anterior cardinal vein to regress. Drainage is variable and can be to:

Associations

Raghib syndrome
