case_images: The SSV had its normal commencement from the lateral end of the dorsal venous arch in the dorsum of the foot and the normal course along the posterior aspect of the leg accompanied by the sural nerve (Figure 1).
case_images: Course of the short saphenous vein (SSV) in the popliteal fossa without communicating with or draining into the popliteal vein and continuing onwards as the Giacomini vein. SN: sciatic nerve; CPN: common peroneal (fibular) nerve; TN: tibial nerve.

case_images: In its further course, instead of draining to the popliteal vein in the popliteal fossa, it crossed the fossa superficially to continue in the lower half of the posterior part of the thigh as the vein of Giacomini, positioned behind the sciatic nerve (Figure 2).
case_images: (A) Further course of Giacomini vein in the middle of the thigh and (B) its course in relation to the structures of the back of the thigh. SN: sciatic nerve; BF: biceps femoris; SSV: short saphenous vein.

case_images: On approaching the middle of the thigh, the SSV curved medially and traversed deep (anterior) to the sciatic nerve and the long head of the biceps femoris (Figure 3).
case_images: Termination of the Giacomini variant of the short saphenous vein (SSV) into the tributaries of the profunda femoris vein (PFV) and the veins of the thigh. SN: sciatic nerve; BF: biceps femoris.

case_images: The former terminated in the tributaries of the profunda femoris vein (PFV) while the latter ended in the veins of the back of the thigh (Figure 4).
