PURPOSE OF REVIEW: The inferior vena cava (IVC) system is the major venous collecting blood network of the human body. This structure is formed in a complicated series of developmental stages between the fourth and eighth weeks of intrauterine life. Alterations in the developing process of the IVC system give rise to an array of different congenital variants or developmental anomalies. RECENT FINDINGS: IVC anomalies are uncommon, usually of little physiological consequence, and mostly discovered incidentally during cross-sectional imaging in otherwise healthy individuals...

Hepatic vena cava syndrome (HVCS) also known as membranous obstruction of inferior vena cava was considered a rare congenital disease and included under Budd Chiari syndrome. It is now recognized as a bacterial infection induced disease related to poor hygienic living condition. Localized thrombophlebitis of IVC at the site close to hepatic veins (HV) outlets is the initial lesion which converts on resolution into stenosis or complete obstruction, the circulatory equilibrium being maintained by development of cavo-caval collateral anastomosis...

Inferior vena cava (IVC) thrombosis, although similar in many aspects to deep venous thrombosis (DVT), has distinct clinical implications, treatments and roles for endovascular management. Etiologies of IVC thrombosis vary from congenital malformations of the IVC to acquired, where indwelling IVC filters have been implicated as a leading cause. With an increasing incidence of IVC thrombosis throughout the United States, clinicians need to be educated on the clinical signs and diagnostic tools available to aid in the diagnosis as well as available treatment options...

With the increased use of cross-sectional imaging, systemic venous anomalies are more frequently being recognized in asymptomatic patients. Accurate characterization of systemic venous anomalies plays a major role in the appropriate selection of a surgical approach or interventional procedure. In this article, we review common and uncommon inferior vena cava (IVC) anomalies. We describe the embryological basis and clinical implications of these anomalies, particularly from an interventional radiology perspective...

The duplication of the inferior vena cava (IVC) is a rare congenital anomaly, which also has some variations regarding the complex embryological development of the IVC. In the typical form, infrarenal IVC segments are duplicated and the left IVC joins the left renal vein, which crosses anterior to the aorta in the normal fashion to join the right IVC. In variant forms, the interruption of the intrahepatic segment of the IVC, azygos or hemiazygos continuation, or retroaortic course of the renal vein may be seen...

Retrocaval ureter or circumcaval ureter is a rare congenital abnormality arising from dysgenesis of the inferior vena cava (IVC) that results in the right ureter coursing behind and medial to the IVC. The ideal nomenclature for the anomaly is preureteral vena cava, keeping in mind the aberrant embryology. It can result in hydronephrosis and is a rare cause of long-standing cyclical pain abdomen. Ultrasound, intravenous urography, nuclear scintigraphy, computed tomography urography (CTU) and magnetic resonance urography (MRU) have been used in the diagnosis of this abnormality but CTU, with its ability to depict the abnormality in three dimensions gives the most "wholesome" solution to its diagnosis...

This paper deals with two recent cases of Inferior Caval Vein (IVC) duplicity, congenital anomaly often but not always asymptomatic that should be considered in the differential diagnosis of flank pain when other more common disorders have been excluded. Here are described the clinical and surgical significance together with the typical sonographic findings useful for the diagnosis of IVC duplicity. Particular attention is given to a peculiar and easily repeatable sonographic aspect associated with IVC duplicity, not previously reported in Literature and that we called the "Neptune's sign"...

BACKGROUND: Tissue-engineered vascular grafts (TEVGs) offer potential to overcome limitations of current approaches for reconstruction in congenital heart disease by providing biodegradable scaffolds on which autologous cells proliferate and provide physiologic functionality. However, current TEVGs do not address the diverse anatomic requirements of individual patients. This study explores the feasibility of creating patient-specific TEVGs by combining 3-dimensional (3D) printing and electrospinning technology...

Congenital anomalies of the inferior vena cava (IVC) are rare but important problems in living donors for kidney transplantation, especially in cases of a short left renal vein and accompanying vascular and urological anatomic variations. However, the clinical impacts of IVC anomalies in deceased donors have yet to be reported. The unexpected presence of an IVC in an unusual position poses challenges to surgeons and increases the risk of bleeding during organ removal. Accompanying vascular variations can cause unexpected bleeding and injury and therefore technical complications in procurement and subsequent implantation...

Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckel's diverticulum. Double inferior vena cava (IVC) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small outpouching in the distal ileum with a band like structure attached to it...

BACKGROUND: Left-sided inferior vena cava (LIVC) and duplicated inferior vena cava (DIVC) are rare asymptomatic congenital abnormalities. Unrecognized, these anomalies can be the source of major injuries and cause serious life-threatening bleeding complications especially during abdominal aortic surgery. METHODS: Retrospective data for patients with 2 major inferior vena cava (IVC) anomalies that underwent aortic surgery over a 13-year period were collected. Patient demographics, type of aortic disease and caval anomaly, surgical approach, type of aortic reconstruction associated with procedure on caval vein, postoperative complications, and in-hospital mortality were recorded...

Congenital anomalies of the inferior vena cava (IVC) are rare and very often diagnosed in asymptomatic patients during computed tomography performed for other purposes. These anomalies can have significant clinical implications, for example if electrophysiology procedures are needed. Diagnostic and ablation procedures are difficult since catheter manipulation and positioning are more complex. We present here a case of successful atrioventricular nodal reentrant tachycardia ablation in a patient with unexpected IVC agenesis, using an azygos route...

The presence of aneurysms in the territory of the inferior vena cava (IVC) is an extremely rare finding in children and few cases have been reported in the literature. Etiology is unknown and some authors have hypothesized that it can be related to a congenital defect. Most cases present as incidental radiologic findings in asymptomatic patients, but can appear as life-threatening massive thrombosis. Clinical presentation is very heterogeneous and it should be included in the differential diagnosis of patients with retroperitoneal masses...

Congenital malformations of the inferior vena cava (IVC) are rare and underreported. They can be a risk factor for deep venous thrombosis (DVT) as a result of inadequate venous drainage of the lower extremities through collateral circulation. The significant number of cases reported in the literature highlights their importance, warranting investigating their existence in younger individuals with idiopathic DVT of the lower extremities and pelvic veins. In this systematic review, we depict the typical presentation of IVC malformations, their management, and the management of their associated DVT...

We report an interesting case of a man with a persistent left superior vena cava (PLSVC) with left azygos vein who underwent electrophysiological evaluation. Further evaluation revealed congenital dilated azygos vein, while a segment connecting the inferior vena cava (IVC) to the hepatic vein and right atrium was missing. The azygos vein drained into the superior vena cava, and the hepatic veins drained directly into the right atrium. The patient did not have congenital anomalies of the remaining thoracoabdominal vasculature...

Klippel-Trenaunay syndrome is a rarely encountered congenital disease characterized by a triad of enlarged arteries and veins, limb hypertrophy and capillary malformations. We are presenting an interesting case of a 23-year male who had been previously diagnosed to have Klippel-Trenaunay syndrome. The patient presented with large pulmonary embolism after having undergone laser surgery for varicose veins. The diagnostic chest computed tomography (CT) performed also revealed the co-existence of severe destructive pulmonary parenchymal disease involving large areas of the pulmonary parenchyma and formation of large emphysematous bullae having an asymmetric involvement of the left lung field...

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...

Partial anomalous pulmonary venous connection (PAPVC) is a rare congenital anomaly that leads to an anatomical left-to-right shunt. Termination of the intrahepatic inferior vena cava (IVC) with its azygos continuation associated with the hepatic venous connection to the left atrium (LA) is also a rare congenital anomaly that results in an anatomical right-to-left shunt. A 65-year-old male presented with severe dyspnea on exertion and pedal edema. He was further diagnosed at our clinic and was found to have both the aforementioned congenital abnormalities, creating a bidirectional shunt...
