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 two 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...

Congenital anomalies of the Inferior Vena Cava (IVC) result from the persistence of the embryonic venous system. Knowledge of such anomaly is of great importance during abdominal surgery, liver and kidney transplantation, renal venous sampling and in the treatment of thromboembolic diseases. Here, we report a rare anatomical variation of dual IVC with normal course of right sided IVC and hemiazygous continuation of left sided IVC with interiliac communication in potential renal donor. Congenital abnormalities of the inferior vena cava are easily identified on Computed Tomography (CT) and should be considered when interpreting any CT of the abdomen or chest...

Duplication of inferior vena cava is an uncommon abnormality and is important in daily today practice for vascular surgeons, radiologist and urologist especially during retroperitoneal surgeries and treatment of thromboembolic disease. Radiologically, Duplicated IVC can be mistaken for lymphadenopathy or left pyeloureteric dilatation. Crossed fused kidney with a single ureter defy the embryological theory of ureteric bud crossing the opposite side and induce nephron formation associated anomaly of Duplication of inferior vena cava and malrotation of gut are not reported in a same patient...

We present two cases of congenital intrahepatic portosystemic shunts in which the right portal vein directly communicated with the inferior venacava (IVC) in one patient and with the hepatic vein in the other. Multiple hepatic nodules consistent with focal nodular hyperplasia (FNH) were seen in the first patient. The second patient presented with recurrent history of hepatic encephalopathy. Percutaneous transhepatic embolization was performed using coils and Amplatz device following which she completely recovered...

OBJECTIVE: Inferior vena cava (IVC) thrombosis is an uncommon condition but can cause devastating complications to those affected. Historically, this has been treated with an open surgical approach (with high morbidity) and with angioplasty in more recent years. Herein we describe technical aspects of stenting of the IVC in patients with recalcitrant chronic occlusive disease and evaluate its outcomes. METHODS: We reviewed all the patients treated in an endovascular fashion for venous disease at our institution from 2005 to 2014 to identify and to include those with IVC stent placement in this study...

Thrombosis of the inferior vena cava (IVC) is an under-recognized entity that is associated with significant short- and long-term morbidity and mortality. In absence of a congenital anomaly, the most common cause of IVC thrombosis is the presence of an unretrieved IVC filter. Due to the substantial increase in the number of IVC filters placed in the United States and the very low filter retrieval rates, clinicians are faced with a very large population of patients at risk for developing IVC thrombosis. Nevertheless, there is a paucity of data and societal guidelines with regards to the diagnosis and management of IVC thrombosis...

The numerous variations of abnormalities of the inferior vena cava (IVC) result in anomalies such as isolated left IVC, double IVC and more than 60 types of malformation. These anomalies are rare and recognized incidentally during surgical or radiological procedures. They may lead to clinical complications during abdominal surgery, and predispose to venous thrombosis. Although they have no definite relationship to other congenital cardiac lesions, identification of these anomalies are important for pre-operative planning and post-operative follow-up...

Retrocaval ureter (pre-ureteral vena cava) is an uncommon congenital anomaly that causes ureteral obstruction by external compression. Although right retrocaval ureter is a common entity, left retrocaval ureter is extremely rare. A left retrocaval ureter is usually associated with situs inversus or duplicated inferior venacava (IVC). An isolated left retrocaval ureter with single left-sided IVC is even rarer and only four cases have been reported in the literature. We present images of a case with isolated left retrocaval ureter with a single left-sided IVC without situs inversus...

OBJECTIVES: To present and test a simple surgical technique that may prevent atrial reentrant tachycardia following surgery for congenital heart disease. This arrhythmia is one of the commonest long-term complications of such a surgery. It may occur many years (even decades) after the operation. It is usually explained as a late consequence of right atriotomy, which is an inherent component of many operations for congenital heart disease. Right atriotomy results in a long scar on the right atrial myocardium...
