Objective: To assess feasibility of robot-assisted laparoscopic radical nephrectomy (RALRN) and inferior vena cava thrombectomy (IVCT) in treating renal tumours with level I-III IVC thrombi and to assess their outcomes.
Patients And Methods: We conducted a retrospective analysis of RALRN-IVCTs, involving four centres across India, from September 2015 to June 2019. We analysed patients who underwent RALRN-IVCT for level I-III thrombi according to the Mayo classification. The total operative duration with console time, length of hospital stay, preoperative and postoperative creatinine, IVC clamp time and intraoperative blood loss were recorded.
Results: Of the 13 patients that underwent RALRN-IVCT, five had a level I thrombus, seven had level II, and one had a level III thrombus. In all, 11 of the patients had right-sided tumours and the remaining two had left-sided tumours. The mean (SD) age of the patients was 56.5 (12.3) years, the mean (SD) operative time was 329.5 (97.22) min, the mean (SD) console time was 222.5 (70) min, the mean (SD) blood loss was 395 (170) mL, and the mean (SD) IVC clamp time was 19.14 (9.5) min. The mean (SD) length of hospital stay was 7.8 (3.27) days. Of the 13 patients, 12 had clear cell renal cell carcinoma (RCC) and one had papillary RCC. The mean (range) follow-up was 19 (4-50) months. One patient had upfront metastasis and two patients developed metastasis, while 10 patients remained disease-free during the follow-up.
Conclusion: With appropriate patient selection, surgical planning and robotic experience, completely intracorporeal robotic level I-III IVCT is feasible and can be performed efficiently. Larger experiences, with longer follow-ups and comparisons with open surgery are needed to confirm these initial outcomes.

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.

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.

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.
