Surgery which involves anterior mediastinal mass resection with artificial replacement of the superior vena cava results in significant disruption to the circulatory system. In this case, a pathway was established to divert blood from the internal jugular to the femoral vein after clamping of the superior vena cava. Blood which would ordinarily return to the right atrium via the superior vena cava was now being returned via the inferior vena cava. The mean arterial pressure was maintained at least 50 mmHg higher than the central venous pressure during clamping of the superior vena cava to avoid cerebral hypoperfusion. The combined use of the above strategies aimed to provide satisfactory surgical conditions and cerebral protection.

For end-stage renal disease (ESRD) patients requiring hemodialysis, reliable vascular access is crucial, especially when conventional supradiaphragmatic options are exhausted. This study reviews the technical aspects, clinical outcomes, and complications of translumbar and transhepatic tunneled dialysis catheter (TDC) placements. These alternative infradiaphragmatic approaches provide essential hemodialysis access for patients with central venous occlusions.

Background: Intraoperative hemorrhage is one of the major complications of orthotopic liver transplantation (OLT) and is mainly caused by technical difficulties of the surgical procedure besides primary liver diseases. The present study aimed to evaluate the feasibility and clinical effects of a novel proceduralized donor liver back-table preparation (DLBTP) technique for use in OLT.
Methods: This retrospective study was conducted between January 2018 and June 2020 based on patients who had undergone OLT.

Disseminated venous thromboembolism (VTE) occurs commonly in cancer patients, who tend to have contraindications to systemic thrombolysis and require cancer surgery. Such clinical scenarios are often challenging to manage. In this case report, we illustrate an innovative, single procedural approach in such a patient to remove extensive VTE, improve symptoms, prevent hemodynamic decompensation, and allow for a minimal level of anticoagulation such that necessary cancer surgery can proceed safely.

Retroperitoneal fibrosis (RPF) is a rare disease with a nonspecific presentation. RPF can be classified into Idiopathic, the most common, or secondary due to malignancy and various medications resulting in chronic inflammation and fibrosis in the retroperitoneum. The complications arise due to the compression of structures in the retroperitoneum.

Aim: Percutaneous vertebroplasty is generally considered a safe procedure, however, cases of cardioembolism and cardiac perforation have been reported.
Case Presentation: A 69-year-old woman was referred to our emergency department after an outpatient echocardiogram revealed a "thrombus-like" formation involving the right heart. Two weeks before she had undergone percutaneous vertebroplasty of the third to fifth lumbar vertebrae due to osteoporotic fractures.
