[Technical points of venous reconstruction for disorders of the superior vena cava].
In recent years, the number of patients with disorders of the superior vena cava due to mediastinal tumors such as malignant thymoma, teratoma and hilus type of lung cancer is now increasing in Japan. For those patients, we have tried to do venous reconstruction for the disorders of the superior vena cava (SVC) due to malignant mediastinal tumors. By these combined surgical procedures such as resection of malignant tumor and SVC reconstruction, curability and longevity of the life were apparently recognized. However, it is very important to select patients of which resection of tumor and venous reconstruction can be carried out by several kinds of examinations such as computed tomography (CT), magnetic resonance angiography (MRA) and venography. There are 3 kinds of reconstruction such as direct suture and patch grafting, as well as bypass grafting with ringed e-PTFE (expanded-polytetrafluoloethylene) prosthetic graft except for endovascular interventions of which number of patients is still few. On the other hand, bypass grafting is also effective for high intracranial pressure with syncope for the patients whose tumors could not be resected, because of huge tumor and diffuse invasion.
