The Wallstent vascular endoprosthesis is an effective initial treatment in superior vena cava syndrome of neoplastic origin. Morbidity and complications are minimal. Clinical relief of symptoms is rapid; therefore, the Wallstent endoprosthesis is highly recommended as the first choice for palliative treatment of superior vena cava syndrome, especially because the clinical decision for subsequent chemotherapy or radiotherapy or surgery is not in any way prejudiced.

SummaryObjective: To evaluate the occurrence of variables detecting myocardial ischemia during or after dental treatment under anesthesia with vasoconstrictor (epinephrine).Methods: vasoconstrictor were included. They were divided into two groups (by drawing envelopes): group I (27 patients) using echocardiogram before and after dental intervention, and determination of biochemical markers (CK-MB mass, CK-MB pressure were also measured in the pre, post-anesthesia and post-dental extraction phases. Doppler echocardiography assessed left ventricular segmental contractility and the occasional occurrence of mitral regurgitation. The usual pharmaceutical treatment prescribed by the cardiologist was maintained in all cases.Results: other patients in group I had CK-MB mass elevation, and ischemia was not observed in any other case, as assessed by or mitral regurgitation were observed in the study. Conclusion:ischemic risks, as long as performed with good anesthetic technique and maintenance of the pharmacological treatment prescribed by the cardiologist.
