We report the usefulness of a technique called direct-MDCT venography in the diagnostic workup of a patient with an inferior vena cava leiomyosarcoma. The technique consists in the injection of contrast agent through both lower limbs achieving maximum enhancement in the inferior vena cava. Images are similar to those of the gold standard conventional cavography. To our knowledge, this is the first description of the direct-MDCT imaging appearance of an inferior vena cava leiomyosarcoma.

Congestive myelopathy secondary to epidural venous engorgement and venous congestion in a patient with Budd-Chiari syndrome and its management through inferior vena cava stenting.
BMJ Case Rep

Budd-Chiari syndrome with obstruction in the inferior vena cava causes increased venous pressure in the azygous-hemiazygous system and paravertebral venous plexus, which is transmitted to the epidural venous plexus, devoid of the valves. It causes epidural venous plexus engorgement and venous congestion and may present rarely with low back pain or radiating pain. However, patients developing lower limb weakness as a complication of Budd-Chiari syndrome is an infrequent and severe presentation.

Tissue-engineered vascular conduits (TEVCs) are a promising blood vessel replacement. In a recent publication in Cell Stem Cell, Park et al. developed TEVCs comprised of decellularized human umbilical arteries lined with shear-trained, human induced pluripotent stem cell (hiPSC)-derived endothelial cells (ECs) that resisted thrombosis and exhibited patency upon grafting into the rat inferior vena cava (IVC).

Background: Transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is primarily performed using the transfemoral approach. However, when this approach is not feasible, the transjugular approach can be used as an alternative.
Case Summary: A 57-year-old man presented with heart failure and persistent New York Heart Association class IV symptoms, refractory to guideline-directed medical therapy, intravenous therapy, and intra-aortic balloon pumping.
Perioperative ultrasound screening of lower extremity veins is effective in the prevention of fatal pulmonary embolism in orthopedic patients.

Patients at high risk of deep vein thrombosis are recommended to undergo lower-extremity ultrasonography to screen for pulmonary embolism (PE); however, there are few reports on whether this can effectively reduce the occurrence of fatal pulmonary embolism (FPE). This study aimed to assess the risk factors associated with PE and to investigate whether perioperative ultrasound screening of lower extremity veins in orthopedic patients can effectively reduce the incidence of FPE. We enrolled 137 patients with PE who underwent orthopedic surgery between 2013 and 2020.
