RESUMO
A persistent left superior vena cava (PLSVC) is a congenital anomaly of the systemic venous system. This anomaly is often discovered as an incidental result during central venous catheterization passing through the left subclavian or the left internal jugular vein. We report two cases of PLSVC in pediatric patients.

Progress in medical and scientific research has increased the chances of survival for young patients with congenital diseases, children who, in the past, would not have had any chance of survival. Nowadays, congenital diseases can be treated with appropriate replacement therapies. These treatments can be difficult to administer in young patients because of the high frequency of administration (sometimes more than a dose per week), the use of intravenous infusion and the long-term or life-term requirement.
RESUMO
The use of central venous catheters (CVCs) represents an important step in the management of the surgical, onco-hematology and critically ill patients. CVCs in neonates, like in adult patients, are mainly used to infuse hyperosmolar solutions, to take blood samples and for hemodynamic monitoring. The need for CVCs is higher in neonates than in adults. Poor peripheral access and the high demand for IV access and blood samples are already valuable indications for a CVC.
