Background: Large vessel sarcomas are rare tumours. Leiomyosarcoma of the inferior vena cava is the most common. About 300 cases have been reported in the literature. They tend to be large, and not develop metastasis. The prognosis of these tumours is poor.
Clinical Case: An 81 year-old woman who complained of pain in the right flank, with no other symptoms. Abdominal computed tomography showed a large retroperitoneal mass, which affected the inferior vena cava, with signs of thrombosis inside. It also encompassed the right renal vein and the right kidney. Excision of the tumour was performed in block, performing an autologous saphenous vein bypass between left the renal vein and proximal segment of inferior vena cava.
Discussion: Leiomyosarcomas of the inferior vena cava are classified according to their relationship with adjacent structures. The clinical signs and symptoms are generally non-specific. Diagnosis is made using computed tomography or magnetic resonance imaging, and biopsy of the retroperitoneal mass. Surgery is the only treatment capable of providing prolonged survival. The surgical management is determined by: the level of involvement, the extension, and the presence or absence of collateral veins. The role of adjuvant therapy is controversial.
Conclusions: Inferior vena cava leiomyosarcomas remain a challenge for surgeons. At present, radical resection with negative margins, offers the highest survival rate. The best results are obtained with a multidisciplinary approach by experienced teams in the management of these tumours.

Impact of cardiac position, morphology and operative technique on long-term fontan outcomes in heterotaxy.
Eur J Cardiothorac Surg

Division of Cardiovascular Surgery, The Labatt Family Heart Centre, The Hospital for Sick Children, Toronto, ON, Canada.
Objectives: This study aimed to assess the outcomes of heterotaxy patients undergone the Fontan operation, focusing on morphological features and surgical techniques.
Methods: Eighty-two consecutive heterotaxy patients who underwent the Fontan operation from 1985 to 2021 were compared to 150 patients with tricuspid atresia (TA) and 144 patients with hypoplastic left heart syndrome (HLHS). The Kaplan-Meier method and Cox proportional hazard model were used to analyze transplant-free survival and predictor of outcomes.

Objective: This study aims to identify factors associated with the detectability of the right adrenal vein (RAV) on preoperative contrast-enhanced CT scans of adrenal venous sampling (AVS) in the era of high-resolution CT (HRCT).
Materials And Methods: In this retrospective study, 36 patients (15 men and 21 women; mean age, 56 y) who underwent preoperative contrast-enhanced CT [11 patients in HRCT with 0.25 mm detector matrix (Cannon Medical Systems) and 25 patients in conventional multidetector CT with 0.
Combining Low-energy Images in Dual-energy Spectral CT With Deep Learning Image Reconstruction Algorithm to Improve Inferior Vena Cava Image Quality.
J Comput Assist Tomogr

Department of Radiology, Affiliated Hospital of Shaanxi University of Chinese Medicine.
Objective: To explore the application of low-energy image in dual-energy spectral CT (DEsCT) combined with deep learning image reconstruction (DLIR) to improve inferior vena cava imaging.
Materials And Methods: Thirty patients with inferior vena cava syndrome underwent contrast-enhanced upper abdominal CT with routine dose, and the 40, 50, 60, 70, and 80 keV images in the delayed phase were first reconstructed with the ASiR-V40% algorithm. Image quality was evaluated both quantitatively [CT value, SD, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) for inferior vena cava] and qualitatively to select an optimal energy level with the best image quality.
Abnormal characteristics of inferior vena cava and abdominal aorta among neonates with early onset septic shock.

Background: The variety of shocks in neonates, if not recognized and treated immediately, is a major cause for fatality. The use of echocardiography may improve assessment and treatment, but its reference values across gestational age (GA) and birth weight (BW) are lacking. To address the information gap, this study aimed at correlating GA and BW of newborns with nonhemodynamic abnormalities, and at evaluating the usefulness of such reference values in neonates with early onset septic (EOS) -shock.

Hemodynamic processes from the portal vein(PV) to the inferior vena cava(IVC) were mimicked for three patients with portal hypertension(PH) and the effects of stent parameters on the outcomes of transjugular intrahepatic portosystemic shunt(TIPS) were investigated through computational fluid dynamics(CFD). The liver region was simulated with porous media model and the spatial distributions of superior mesenteric vein(SMV) and splenic vein(SV) blood were solved through the Eulerian multiphase model. The present method is able to simulate the PH flow and predict the PV pressure, the stent shunt rate and the SMV blood proportion after TIPS treatment.
