Abstract: Inferior vena cava anomalies are rare, occurring in up to 8.7% of the population, as left renal vein anomalies are considered. The inferior vena cava develops from the sixth to the eighth gestational weeks, originating from three paired embryonic veins, namely the subcardinal, supracardinal and postcardinal veins. This complex ontogenesis of the inferior vena cava, with multiple anastomoses between the pairs of embryonic veins, leads to a number of anatomic variations in the venous return from the abdomen and … Show more

“…The infrarenal IVC segment derives from the right suprarenal vein and from its anastomoses with the subcardinal vein. The iliac veins derive from the post cardinal veins [36]. Anomalies of the IVC result from the abnormal development in regression and anastomoses of these three pairs of embryonic veins.…”

“…Superior vena cava (SVC), inferior vena cava (IVC) and left renal vein (LRV) variations are not rare at all, and they have been diagnosed with an ever-increasing rate (1)(2)(3)(4). Vena cava variations may stay asymptomatic throughout a lifetime (4).…”

“…Anomalies of the IVC are associated with lower extremity DVT, venous insufficiency, hematuria, and other congenital abnormalities. 3 The prevalence of AIVC is estimated to be 5% in young patients with DVT. 4,5…”

“…1 Multiple anomalies of the IVC have been reported, including a double, left-sided, and partial or complete absence of the IVC. 2,3 These variations are believed to occur in the early weeks of gestational development as multiple embryonic veins coalesce and ultimately form the IVC. Although an absent IVC is rare, previous reports suggest up to 5% of patients less than 30 years old diagnosed with idiopathic deep vein thrombosis (DVT), have such anomalies.…”
