Giacomini vein

The Giacomini vein or thigh extension of the short saphenous vein refers to a variation in lower limb venous anatomy where the short saphenous vein (SSV) continues through to the thigh as a distinct branch.

The persistence of this vein may play a contributory role in the development of chronic venous disease. It is therefore an important vein to assess in Duplex venous ultrasound assessment of the lower limb. 

Epidemiology

Its reported prevalence in some form or another may ~75% in the general population 4,5.

History and etymology

It is named after Dr Carlo Giacomini, later Professor of Anatomy at the University of Turin, Italy, who presented a thesis on superficial and deep lower limb venous anatomy in July 1873 3.
