Drains to great saphenous vein

The Giacomini vein is a communicant vein between the great saphenous vein (GSV) and the small saphenous vein (SSV). It is named after the Italian anatomist Carlo Giacomini (1840-1898). The Giacomini vein courses the posterior thigh as either a trunk projection, or tributary of the SSV. In one study it was found in over two-thirds of limbs.[1] Another study in India, found the vein to be present in 92% of those examined.[2]It is located under the superficial fascia and its insufficiency seemed of little importance in the majority of patients with varicose disease, however the use of ultrasonography has highlighted a new significance of this vein.[3] It can be part of a draining variant of the SSV which instead of draining into the popliteal vein, continues on to reach the GSV at the proximal 1/3 of the thigh. The direction of its flow is usually anterograde (the physiological direction) but it can be retrograde when this vein acts as a bypass from an insufficient GSV to SSV to call on this last one to collaborate in draining. Many discussions exist about this vein, some of them confusing to a non-expert reader.[4]Insufficiency in the Giacomini vein can present in isolation but is mostly seen together with a GSV insufficiency. It has been shown to be effectively treated either with endovenous laser ablation or by ultrasound guided sclerotherapy.[5]
