[Transient ischemic attacks in a patient with superior vena cava obstruction: case report]. / Ataques isquêmicos transitórios em paciente com síndrome da veia cava superior. Relato de caso.

The superior vena cava obstruction is a relatively rare condition. We report the case of a 42 year old man suffering of hypertension for about fifteen years. He reported a cervical and thoracic pain for one year, that was related to a 95% of occlusion on the right coronary artery. An angioplasty has been done but the patient still related the thoracic pain. Afterwards the patient had recurrent episodes of right hemiplegia and hypertensive emergencies that have been treated with anti-hypertensive agents. A venous disease was suspected because of cyanosis in the face especially when episodes of transient ischemic attacks occurred. A venography showed obstruction of the right jugular vein near the junction with the superior vena cava. In conclusion, it was not possible to define with certainty the relationship between the two pathologies presented by the patient, even so, we call attention to the improvement of the neurological symptoms after the control of superior vena cava obstruction with the treatment.
