Morphological study on the human anterior cardiac veins, venae cordis anteriores

The way in which the anterior cardiac veins end in the right atrium is very inconstant; separate opening is very rare and course and situation also changes a lot. We found the vein of Galen in about 90.59% of the cases and its ending differs from the usual. We found the anterior ventricular veins in about 91.45% of the cases; there is only one such vein in 57.00% of the cases, two in 33.64% and three in 9.34%; their origin and opening vary greatly. We saw the vein of Cruveilher in 68.37% of the cases, a lower percentage than that found by other authors. It also differs in its origin, course and opening. The vein of Zuckerkandl was found in 47.00% of the cases, lesser percentage than that found by other authors. The common canal is very important and very frequent in our cases. It opens into the right atrium by one orifice in 27.68% of the cases, by two in 63.93% and by three in 8.19%.
