NON–COMMUNICATING BILATERAL SUPERIOR VENACAVA–A CASE REPORT AND BRIEF LITERATURE REVIEW

Dr. Pallavi

Abstract :

 Abnormalities of the central vascular system are always of extreme interest, on account of the light they 

cast on many developmental problems.Normal anatomy describes the formation of superior venacava by 
the union of right and left achiocephalic veins draining the head and neck area. Presence of bilateral superior venacava was encountered during routine dissection in the Department of Anatomy, Kasturba medical college, Manipal. 
Right and left superior venacavae were formed as a continuation of respective achiocephalic veins. The left superior 
venacava drained into the right atrium via the coronary sinus which was enlarged. No communication was observed 
between the two venacavae indicating that the right and left halves of the head and upper limb drain back to the 
heart independently. Persistence of the left anterior cardinal vein and regression or absence of the communicating vein 
would be the possible emyological explanation for this anomaly. Literature reviews suggest that the frequency of its 
occurrence is 0.3%–1.3% in general population but higher (10–11%) in people with congenital heart diseases. Although 
it has no physical derangement per se, may complicate or mislead the placement of cardiac catheters or pacemaker 
leads. Dilated coronary sinus may cause cardiac arrhythmias due to stretching of the AV node and bundle of His. Presence of these anomalies is an indication for the screening of other associated cardiac abnormalities.
