Project description:A patient with Marfan syndrome undergoing Bentall operation was found to have an absent right superior vena cava and persistent left superior vena cava. The dilation of coronary sinus raised the suspicion of persistent left superior vena cava. The diagnosis was confirmed by agitated saline contrast echocardiography and computed tomography of the chest.
Project description:Aneurysms of mediastinal systemic veins are extremely rare, usually asymptomatic and incidentally diagnosed during chest radiography. We describe the case of a giant superior vena caval aneurysm in a 14-year old male following Glenn surgery and discuss its complications and management.
Project description:A patient planned to be performed catheter ablation. However, three-dimensional contrast-enhanced chest computed tomography revealed isolated persistent left superior vena cava. We should know such an anatomical abnormality especially when central venous catheter or peripherally inserted central catheter is inserted from right jugular vein or right subclavian vein.
Project description:Total superior vena cava (SVC) clamping for SVC replacement or repair can be used in thoracic surgery. A bypass technique is an option to avoid hemodynamic instability and cerebral venous hypertension and hypoperfusion. The present report describes a venous bypass technique using Anthron bypass tubeTM for total SVC clamping. Indications for this procedure include the need for a temporary bypass between the brachiocephalic vein and atrium for complete tumor resection. This procedure allows the surgeons sufficient time to complete replacement of SVC or partial resection of SVC without adverse effects. Further, it is a relatively simple procedure requiring minimal time.
Project description:Nifekalant successfully suppressed intra-superior vena cava fibrillation, which complicated the evaluation of the gap of superior vena cava isolation.
