TY - JOUR T1 - Anomalous venous circuit: a detour to the heart JF - BMJ Case Reports DO - 10.1136/bcr-2012-006680 VL - 2012 SP - bcr2012006680 AU - Omair Ali AU - Abdul Wase Y1 - 2012/11/21 UR - http://casereports.bmj.com/content/2012/bcr-2012-006680.abstract N2 - We report a case of a complicated vascular access secondary to systemic venous defects, which have not been previously reported.

The clinical and surgical considerations of such an anomaly are discussed therein. We look at embryological origins of such a merger and share our experience in troubleshooting through the anomaly.
