Discovery of an accessory greater saphenous vein - a case study

The greater saphenous vein (GSV) is a vital structure in the lower extremity with well-documented anatomical variations. This case report describes the unexpected discovery of an accessory GSV during a routine cadaveric dissection at the University of Rwanda's School of Medicine and Pharmacy. The accessory GSV ran parallel to the main GSV before rejoining it higher in the leg. This finding underscores the importance of recognizing anatomical variations like accessory GSVs, which can influence clinical procedures and outcomes. Increased awareness among clinicians and educators is crucial, and further research is needed to assess the prevalence and clinical implications of this rare anatomical variant.
