Left inferior vena cava
 Discussion of Left inferior vena cava
- A left IVC results from regression of the right supracardinal vein with persistence of the left supracardinal vein.
- The prevalence is 0.2%–0.5% .
- The major clinical significance of this anomaly is the potential for misdiagnosis as left-sided paraaortic lymphadenopathy.
- Spontaneous rupture of an abdominal aortic aneurysm into a left IVC has been reported.
- Transjugular access to the infrarenal IVC for placement of an IVC filter may be difficult.
 Imaging Findings for Left inferior vena cava
- Typically, the left IVC joins the left renal vein, which crosses anterior to the aorta in the normal fashion, uniting with the right renal vein to form a normal right-sided prerenal IVC.
