Abnormalities of the inferior vena cava (IVC) and renal veins are extremely rare. However, with the increasing use of computed tomography (CT), these anomalies are more frequently diagnosed. The majority of venous anomalies are asymptomatic and they include left sided IVC, duplicated IVC, absent IVC as well as retro-aortic and circumaortic renal veins. The embryological development of the IVC is complex and involves the development and regression of three sets of paired veins. During renal surgery, undiagnosed venous anomalies may lead to major complications. There may be significant hemorrhage or damage to vascular structures. In addition, aberrant vessels may be mistaken for lymphadenopathy and may be biopsied. In this review we discuss the embryology of the IVC and the possible anomalies of IVC and its tributaries paying particular attention to diagnosis and implications for renal surgery.

Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia.

Rationale: We report the efficacy of combination prednisolone and intravenous (IV) rituximab as an immunosuppressive regimen for a young male presenting with extensive venous thromboembolism including a submassive pulmonary embolism secondary to life-threatening nephrotic syndrome from very high risk anti-phospholipase-A2 receptor (PLA2R) positive membranous nephropathy. Initial treatment was with mechanical thrombectomy and anticoagulation. Thereafter, oral prednisolone was initiated to induce remission, during a period of uninterrupted anticoagulation.

Knowledge of variations of the testicular vessels is essential for urologists, radiologists, and surgeons in general, as iatrogenic injuries of these vessels may affect the spermatogenesis severely. Though variations of testicular vessels are common, combined variations of these vessels are rare. We observed concurrent variations of left testicular vessels in an adult cadaver aged 70 years.

: Vascular access complications, particularly high venous pressure, pose significant challenges for hemodialysis patients undergoing hemodialysis. Limited research has focused on identifying predictive factors for invasive treatment. This study aimed to identify patients who might benefit from frequent monitoring and conservative management based on duplex ultrasound (DUS) evaluation.

Two unique presentations of renal anatomy were observed during routine cadaveric dissection. The first case presented with an ectopic malrotated left kidney supplied by supernumerary renal arteries. This kidney was drained by a circumaortic renal vein and an inferior polar vein.
