Inferior Vena Cava Duplication: Incidental Case in a Young Woman

Abstract

A case of a double inferior vena cava (IVC) with retroaortic left renal vein, azygos continuation of the IVC, and presence of the hepatic portion of the IVC drained into the right renal vein is reported and the embryologic, clinical, and radiological significance is discussed. The diagnosis is suggested by multidetector computed tomography (MDCT), which reveals the aberrant vascular structures. Awareness of different congenital anomalies of IVC is necessary for radiologists to avoid diagnostic pitfalls and they should be remembered because they can influence several surgical interventions and endovascular procedures.

Unusual coexistence of double inferior vena cava with nutcracker syndrome–a case report and review of the literature

“…23 For example, the case of a doubled IVC with retroaortic LRV, azygos continuation of the IVC, and the presence of a hepatic portion of the IVC that drained into the RRV has been reported. 8 Furthermore, a similar case in a 74-year-old male patient has been described, in which the patient was diagnosed due to an enlarged juxtarenal abdominal aortic aneurysm. 24 During imagery examination, the following anomalies in vessel course were noticed: the left IVC joined to the LRV, then crossed the abdominal aorta posteriorly, met the right IVC and continued cephalad as the azygos vein.…”

“…Unrecognised anomalies prior to medical procedures may lead to interruption of veins and severe haemorrhage. 3,4,6,8,9 To the best of the authors' knowledge, the present case is a unique description of duplicated IVC coexisting with nutcracker syndrome, presented using two complementary radiological techniques.…”

“…Two-dimensional and three-dimensional images can aid in the visualisation and understanding of complex vascular malformations of the IVC. 11 …”

Acute mesenteric venous thrombosis in pregnant women with thrombophilia and doubled inferior vena cava

“…Выявленная при мультиспиральной компьютерной томографии аномалия развития -удвоение нижней полой вены -свидетельствует о нарушении процессов эмбриогенеза на 6-10-й неделе гестации [10,11]. В данном наблюдении это явилось диагностической находкой, не влияющей на течение заболевания, но при необходимости проведения вмешательств на органах забрюшинного пространства знание таких аномалий может быть полезным.…”

“…Другие исследователи описывают идиопатический мезентериальный венозный тромбоз на фоне протекающей беременности [2,4,[7][8][9]. Аномалии развития нижней полой вены встречаются в 0,2-3% наблюдений и чаще являются случайной патологоанатомической, операционной находкой или обнаруживаются современными высокоточными методами исследования [10,11].…”
