ABSTRACT

We report the first two cases of superior vena cava syndrome. The clinical suspicion was made in base of a history of a catheter in superior vena cava and signs of swelling of the head, neck and upper extremities, cianosis of the upper body and prominent venous pattern about the head and neck.
The venous compromise may produce recurrence of clinical signs at a later time. Confimation of clinical suspicion is obtained through radiographic means. Contrast injection will confirm central occlusion and collate-ralization.
We documented thrombosis without an obstructed catheter by echocardiography and at surgery time.
There are predictores of risk of complications like longer duration of catheteriztion, the use of total parenteral nutrition, solutions infused and surgical techniques.
Thrombosis around catheter adherent to vassels walls may partially or completely obstruct Iarge vas-sels.
Two-dimensional echocardiography is extremely useful in the assessment of catheterrelated intravas-cular thrombi. This allows noninvasive imaging of the cateter and serial evaluation of thrombi.
The important point is to take in mind this complications as a consequences of the use of long-term Indwelling central venous lines.
