“…The duplicated inferior vena cava has a reported incidence of 2-3% in autopsy studies [15,18]. However, this anomaly diagnosed by CT, was only 0.3-0.6% [13,16]. This difference in occurrence suggests that the smaller component is not readily apparent on CT.…”

“…These veins usually join to form one vein at the level of the origin of the renal arteries [1,2]. It is a rare developmental variant that has been reported to occur in 0.2-4% of the population [13][14][15][16]. However, coexistence of duplication of the inferior vena cava with the abdominal aortic aneurysm is described only in a few studies [5,[17][18][19], in which it accompanies other vascular variations [18] or developmental anomalies [20].…”

“…It is formed by the sequential formation, anastomoses, and regression of three paired veins (posterior cardinal, subcardinal, and supracardinal veins) [13,14,44]. At this time, there is an anastomotic junction between supracardinal and subcardinal channels, which produced a collar of veins around the aorta.…”

Four major variations of the venous system in the retroperitoneal space are the retroaortic left renal vein, left renal vein collar, left-sided inferior vena cava, and caval duplication. During surgery, especially, injury in veins is responsible for the most unexpected intraoperative bleeding. Therefore, above-mentioned anomalies pose potential hazards to surgeons during treatment of abdominal aortic aneurysm. Preoperative diagnosis is highly desirable but is not always available so, during abdominal surgery, familiarity with the anatomy of the most common types of venous variations is the first step toward preventing vascular injury. The chapter includes information describing the demographic, clinical, and morphological characteristics of the presence of the aforementioned main vein anomalies including: gender distribution, frequency in population, the most commonly reported symptoms, and associate complications. Massive intraoperative bleeding may be dangerous during aortic dissection; however, venous bleeding is more complicated than arterial hemorrhage. Significant venous bleeding, in particular, can occur if major retroperitoneal venous anomalies are present. The anomalous veins are typically thinwalled, dilated, and tortuous. As a result, manipulation of these veins during abdominal aortic surgery places the patient at high risk of long-term massive hemorrhage.

“…Variations of IVC may occur due to many complicated transformation processes during embryonic life [15,19]. Anatomical variation of the IVC occurs in 0.4-4% of the population [14]. Among the abnormalities related to the formation of the IVC, the double IVC (DIVC) was the most common anatomic variation [3].…”

“…Bilateral inferior vena cava (IVC) is a relatively rare anomalous condition, which can be correctly diagnosed on the basis of computed tomography (CT) findings without angiography (1)(2)(3)(4). Other retroperitoneal veins may be dilated in certain circumstances such as portal hypertension or postpartum state and located at the left side of the aorta similar to the left IVC (5)(6)(7)(8)(9)(10).…”
