The superior vena cava syndrome is due to the increased venous pressure in the upper torso, neck and head, caused by the obstruction of the superior vena cava. Both external and internal factors cause obstruction (95% are malign causes), and the most severe manifestation is represented by cerebral edema that can even lead to coma. The diagnostic algorithm for the superior vena cava syndrome is widely known. There are many controversies and discussions about the safety of histopathological sampling. The purpose of this paper is to assess such risks, the complication rate and the diagnostic yield of surgical sampling, by analyzing the 26 interventions performed in our clinic. Although the complication rate was higher than that observed in the absence of the superior vena cava syndrome, surgery remains mandatory for a rapid histopathological diagnosis, therefore demanding a protocol that must include a mandatory extemporaneous exam of the biopsy.

Isolated right superior vena cava (RSVC) drainage into the left atrium (LA) is a rare congenital anomaly, presenting diagnostic and management challenges. This study presents two cases of isolated RSVC drainage into the LA alongside a comprehensive literature review to improve understanding and delineate optimal surgical approaches. The study describes two cases of isolated RSVC drainage into the LA and their surgical management.

Fibrosing mediastinitis is a rare chronic inflammatory condition characterized by excessive fibrotic process in the mediastinum. Although various infectious processes are more common causes, it can also be related to several malignancies. We report a case of a 28-year-old woman with fibrosing mediastinitis related to an aggressive primary gray-zone lymphoma causing complete occlusion of the superior vena cava (SVC) and the innominate veins.

Objective: This study sought to present the endovascular approach of transcatheter aspiration using the FlowTriever (Inari Medical) aspiration system for high surgical risk patients with right-sided infective endocarditis.
Key Steps: General anesthesia and transesophageal echocardiogram guidance; ultrasonography-guided femoral vein access, preclosure sutures, and insertion of a 24-F sheath; insertion of straight 24-F aspiration cannula over a stiff wire, parked in the superior vena cava; introduction of a 20-F curved cannula inside the 24-F cannula to create a telescopic assembly; accurate positioning using the right ventricle inflow/outflow projection in biplane mode; adjustment of the curved cannula radius by sliding the inner cannula in and out inside the mother cannula; manual aspiration of the vegetation; Postaspiration transesophageal echocardiogram assessment.
Potential Pitfalls: Avoid leaflet and annular injury and account for potential embolization.
