Dec 26, 2015 · Duplicated, or bifid, vein systems are relatively common and mainly involve the femoral vein and popliteal vein . A potentially confusing anatomical variation occurs in patients who have a large deep femoral vein in the thigh running as a large trunk between the popliteal vein and the common femoral vein.

Duplication of the femoral vein was considered when a deep venous channel that was in contiguity with the femoral vessels communicated with the femoral vein or popliteal vein inferiorly and re-entered the femoral vein superiorly or had a common ending with the femoral vein.

Mar 30, 2017 · During my last doppler, I was diagnosed with a bifid (duplicate) vein system in my distal femoral and popliteal veins. According to my hematologist, this, is a contributing risk factor for DVT's (I'm on my second).

Femoral vein catheterization is the easiest and safest method for obtaining temporary vascular access in hemodialysis patients. Therefore, an attempt has been made to report the case of duplication of femoral vein and elaborate its embryological and clinical aspects.

A large lateral thigh tributary or lateral element of a bifid system can easily lead to misinterpretation of the anatomy: the lateral vein is mistaken as the GSV and the medial vein as the femoral and are treated as such, thus leaving the long saphenous complex intact.

Sep 28, 2010 · Femoral vein duplication is a common anatomical variant of the lower limb deep venous system. Ultrasound in skilled and experienced hands with the latest ultrasound units can readily demonstrate this venous anomaly on a consistent basis.

Background: Duplication of the popliteal and superficial femoral veins (PV, SFV) is a normal variant previously reported in up to 25% of limbs. Little clinical significance, however, has been attributed to this apparently common anomaly.

Jun 30, 2019 · Although most (90%) venous thrombosis occurs within the deep lower extremity veins, venous thrombosis may be present at any level of veins in the lower and upper extremities, as well as in the visceral veins, the head and neck veins, and the superior and inferior vena cava.

When used to assess the veins in the lower limb, duplex ultrasonography is able to assess both the deep, superficial and perforating veins to give important information on anatomical patterns of veins, vein patency, vein diameters and valve function.

Dec 30, 2019 · The femoral vein is bifid or duplicated in about 25% of patients ( Fig. 18.21). It continues down the thigh, serving as the primary route of venous drainage until, at the proximal end of the adductor canal, it dives deep and becomes the popliteal vein.
