PATHOLOGY

Detailed explanation-1: -Where is the vena cava located? Your inferior vena cava and superior vena cava are both on your heart’s right side. Your right and left innominate (or brachiocephalic) veins merge to form your superior vena cava.

Detailed explanation-2: -A right-sided SVC that drains into the LA is a rare congenital abnormality, and only a few cases have been reported. In our patient, due to the injection of agitated saline into the right antecubital vein, the agitated saline traveled through the right SVC and then drained directly into the LA.

Detailed explanation-3: -Transposition of inferior vena cava (also known as left-sided IVC) refers to a variant course of the inferior vena cava. It is the most common anomaly of IVC and occurs due to persistence of left supracardinal vein.
