Background: The aim of the study was to review our three year experience with translumbar insertion of dialysis catheters.
Methods: In five adult patients (4 males and one female, mean age 45 yr), requiring dialysis due to end-stage chronic renal failure, the inferior vena cava was cannulated because of the impossibility of using any other approach. All procedures were performed under fluoroscopy. After visualisation of the inferior vena cava by injection of contrast medium into a peripheral vein, the vena cava was punctured with a 20 cm long needle, at the L3 level. The position of the needle was confirmed by injection of contrast medium, and the vein was then cannulated with a peel-away cannula, using a standard Seldinger technique. Subsequently, a pre-tunneled silastic catheter was introduced and secured.
Results: The catheters were used for from 3 to 10 months. No case of permanent catheter dysfunction was noted. Three episodes of temporary thrombosis, in two patients, were successfully treated with heparin and urokinase. Three catheters became contaminated, but they were treated without the necessity for catheter removal.
Conclusion: The described method is a safe and effective way of securing haemodialysis access in patients where a standard approach is not possible.

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.

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.

We demonstrate an aberrant ramification pattern of the renal and testicular vessels. On both sides, the anterior and posterior renal veins emerged from the renal. On the right side, the anterior renal vein collected the right testicular vein and drained into the inferior vena cava, while the posterior one directly drained into the inferior vena cava.

Introduction: There is a risk of iatrogenic vascular injuries during robotic-assisted laparoscopic excision of diaphragmatic endometriosis. Although studies are limited, the first reported case of a suprahepatic inferior vena cava (IVC) injury during robotic diaphragmatic endometriosis excision was successfully treated using a fibrin sealant patch, preventing exsanguination and conversion to laparotomy.
Case Description: A 36-year-old female with a history of recurrent catamenial pneumothorax and two prior video-assisted thoracoscopic surgeries to treat diaphragmatic endometriosis presented to our clinic with right-sided shoulder pain and a chest tube in place.
