Anomalous sub aortic left brachiocephalic vein: a case report

Abstract

The left brachiocephalic vein occasionally follows an aberrant course. It is usually associated with congenital cardiac anomaly. We present a case of anomalous left brachiocephalic vein which followed a sub aortic course, with no cardiac abnormality. Multi detector computed tomography is very useful in accurate diagnosis of this condition and prevents any further investigation in cases of isolated abnormalities. Keywords: Anomalous left brachiocephalic vein; Mediastinal mass; Computed tomography; Chest.A veia braquiocefálica esquerda, ocasionalmente, segue curso aberrante. Esta variação freqüentemente está associada com anomalias congênitas do coração. Neste trabalho é apresentado um caso de veia braquiocefálica esquerda anômala, com trajeto subaórtico, sem anormalidade cardíaca. A tomografia computadorizada com multidetectores é muito útil no correto diagnóstico dessa condição e permite a conclusão diagnóstica, sem quaisquer outras investigações.

An Extremely Rare Reason for Failure of Left Sided Pacemaker Implantation

“…Persistent left superior vena cava (LPSVC) is the most common systemic venous anomaly of thorax with the incidence of 0,5% [ 3 ]. However isolated anomaly of the left brachiocephalic vein (LBCV) is extremely rare [ 4 ]. Anomalies of the LBCV are clinically silent unless accompanying cardiac defects, but the anomalies of the LBCV might pose a challenge if invasive procedures are scheduled to be driven through this route.…”
