\begin{abstract}
PURPOSE: Systemic venous anomalies encompass a wide range of
cardiovascular anomalies. Systemic venous anomalies are relatively
infrequent and, under normal circumstances, asymptomatic, but may be
clinical importance in cardiac surgery. This study aims to investigate
whether systemic venous anomaly would have an effect on the any surgical
planning. METHODS: We included a total of 525 consecutive patients (310
males, 215 females) who underwent open heart surgery for congenital
heart disease. Patients were classified due to type of systemic venous
anomalies. Demographic data and outcome data were retrospectively
analyzed. RESULTS: Systemic venous anomaly was observed in 40 (13,25\%)
patients. The mean age and weight of the patients was 11.5 months
(range, 1 day to 18 years), 9.3 kg (range, 500 gr-65 kg) respectively.
Preoperative diagnosis was obtained in 14 / 40 (37.5\%) patients with
echocardiography, 12 / 40 (30\%) with computed tomography scan, in 7 /
40 (17.5\%) patients with conventional angiography and in 7/40 (17.5\%)
patients during surgery. A persistent left superior vena cava is the
most common systemic venous anomaly (24 / 40 (60\%) patients) and in
others IVC interruption, retroaortic innominate vein and connection of
PSSVC-LA was determined 7 / 40 patients (17.5\%) , 4 / 40 patients
(10\%) and 4 / 40 patients (10\%) respectively. No operative morbidity
and complication associated with systemic venous anomalies was seen.
CONCLUSION: Knowledge of the different course of the systemic venous
anatomy prior to surgical intervention is important for the safe
execution of any cardiac procedure.%
