Left Inferior Vena Cava and Right Retroaortic Renal Vein

Nowadays, incidental anatomical variants are frequent findings, due to the widespread diffusion of cross-sectional imaging. This case report illustrates a fairly uncommon anatomical variant, that is, the copresence of left inferior vena cava and retroaortic right renal vein reported in a 46-year-old lady, undergoing a staging CT for breast cancer. Although the patient was asymptomatic, the authors highlight potential risks related to the above-mentioned condition and the importance of correct identification and diagnosis of the findings.

ABSTRACT OBJECTIVE: The normal anatomic course of the left renal vein (LRV) from the kidney to inferior vena cava (IVC) is usually preaortic. It is called retroaortic left renal vein (RLRV) when located between the aorta and vertebra; the circumaortic left renal vein (CLRV) has both a preaortic and retroaortic course. In this study, we aimed to find the incidence and characteristics of LRV abnormalities in routine abdominal CT and MR examinations conducted in our clinic. MATERIALS AND METHODS: A total of 2189 abdominal CT and MR examinations, performed between April 2007 and June 2009, were reviewed retrospectively for retroaortic and circumaortic LRV abnormalities. RESULTS: LRV abnormalities were detected in 50 (2.3%) examinations. Forty-four of these (2%) were RLRV and 6 (0.3%) were circumaortic LRV abnormalities. CONCLUSIONS: Preoperative knowledge of LRV abnormalities facilitates the safe performance of surgery and reveals the clinical symptoms. It is easy to see LRV and its drainage way on routine CT and MR imagings

Inferior vena cava filters are commonly encountered devices on diagnostic imaging that were highlighted in a 2010 Food and Drug Administration safety advisory regarding their complications from long-term implantation. The Predicting the Safety and Effectiveness of Inferior Vena Cava Filters (PRESERVE) trial is an ongoing after-market study investigating the safety and utility of commonly utilized filters in practice today. While most of these filters are safe, prompt recognition and management of any filter-associated complication is imperative to prevent or reduce the morbidity and mortality associated with them. This review is aimed at discussing the appropriate utilization and placement of inferior vena cava filters in addition to the recognition of filter-associated complications on cross-sectional imaging. An overview of the PRESRVE trial filters is also provided to understand each filter's propensity for specific complications.

ObjectiveDynamic changes in anatomic geometry of the inferior vena cava from changes in intravascular volume may cause passive stresses on inferior vena cava filters. In this study, we aim to quantify variability in inferior vena cava dimensions and anatomic orientation to determine how intravascular volume changes may impact complications of inferior vena cava filter placement, such as migration, tilting, perforation, and thrombosis.MethodsRetrospective computed tomography measurements of major axis, minor axis, and horizontal diameters of the inferior vena cava at 1 and 5 cm below the lowest renal vein in 58 adult trauma patients in pre-resuscitative (hypovolemic) and post-resuscitative (euvolemic) states were assessed in a blinded fashion by two independent readers. Inferior vena cava perimeter, area, and volume were calculated and correlated with caval orientation.ResultsMean volumes of the inferior vena cava segment on pre- and post-resuscitation scans were 9.0 cm3and 11.0 cm3, respectively, with mean percentage increase of 48.6% ( P < 0.001). At 1 cm and 5 cm below the lowest renal vein, the inferior vena cava expanded anisotropically, with the minor axis expanding by an average of 48.7% ( P < 0.001) and 30.0% ( P = 0.01), respectively, while the major axis changed by only 4.2% ( P = 0.11) and 6.6% ( P = 0.017), respectively. Cross-sectional area and perimeter at 1 cm below the lowest renal vein expanded by 61.6% ( P < 0.001) and 10.7% ( P < 0.01), respectively. At 5 cm below the lowest renal vein, the expansion of cross-sectional area and perimeter were 43.9% ( P < 0.01) and 10.7% ( P = 0.002), respectively. The major axis of the inferior vena cava was oriented in a left-anterior oblique position in all patients, averaging 20° from the horizontal plane. There was significant underestimation of inferior vena cava maximal diameter by horizontal measurement. In pre-resuscitation scans, at 1 cm and 5 cm below the lowest renal vein, the discrepancy between the horizontal and major axis diameter was 2.1 ± 1.2 mm ( P < 0.001) and 1.7 ± 1.0 mm ( P < 0.001), respectively, while post-resuscitation studies showed the same underestimation at 1 cm and 5 cm below the lowest renal vein to be 2.2 ± 1.2 mm ( P < 0.01) and 1.9 ± 1.0 mm ( P < 0.01), respectively.ConclusionsThere is significant anisotropic variability of infrarenal inferior vena cava geometry with significantly greater expansive and compressive forces in the minor axis. There can be significant volumetric changes in the inferior vena cava with associated perimeter changes but the major axis left-anterior oblique caval configuration is always maintained. These significant dynamic forces may impact inferior vena cava filter stability after implantation. The consistent major axis left-anterior oblique obliquity may lead to underestimation of the inferior vena cava diameter used in standard anteroposterior venography, which may influence initial filter selection.

Abstract Scimitar syndrome is a rare variant of anomalous right pulmonary vein connection to the inferior vena cava and it is associated with other cardiopulmonary anomalies. It generally requires surgery and sometimes it may go unrecognised into adulthood. We report a unique case of a scimitar syndrome variant in a young adult, who was successfully treated percutaneously, after the first misdiagnosis of arrhythmogenic ventricular cardiomyopathy. The cardiac magnetic resonance unveiled the uncommon anatomical pattern, avoiding surgical repair. Cross-sectional imaging is extremely useful in the diagnosis and treatment planning of CHD in adults.

The case was found on an organic sample consisting of the two kidneys with the renal pedicles and the corresponding segments of the abdominal aorta and inferior vena cava. From the inferior face of the left renal vein, on the lower side of the aorta, a venous branch with an upward path of 8.02 mm was detached, passing on the anterior face of the aorta, passing before its right side, in order to end on the left side of the inferior vena cava, 13.9 mm above the end of the left renal vein in the inferior vena cava, this branch thus describing a periaortic ring (necklace), in which on the left side of the aorta the inferior adrenal vein ends. The periaortic ring (necklace) had a cross-sectional dimension of 3.2 mm and a vertical one of 1.7 cm. On the right side of the aorta, a 2.9 mm venous branch came out of the renal vein, ending on the left side of the inferior vena cava, 1.2 mm above the end of the left renal vein. At the level of the right kidney there were two renal arteries, superior and inferior. Between the two arteries there was an interval of 5.1 cm.
