Venous Anatomy Lower Extremity

Lower extremity venous anatomy. The antegrade flow of blood within these veins is ensured by a system of muscular venous pumps.

This vein is a conjunction of the dorsal vein of the great toe and the dorsal venous arch of the foot.

Venous anatomy lower extremity. And the perforating veins that penetrate the muscular fascia and connect the superficial and deep veins. Where is a common location for varicosities in the lower extremity veins. The deep veins accompany the major arteries and their branches and are usually paired.

As a general rule the deep veins accompany and share the name of the major arteries in the lower limb. The deep venous drainage system of the lower limb is located beneath the deep fascia of the lower limb. The lower extremity venous system includes the superficial deep and perforating veins.

The lower extremity venous anatomy is divided into three interconnected systems. The superficial veins which are above the deep fascia and drain the cutaneous microcirculation. Veins of the lower limb.

However only a few of these are clinically important. Deep system the deep system consists of the common femoral vein the femoral vein the deep femoral vein the popliteal vein and the deep veins of the calf. The sciatic vein the main trunk of the primordial deep venous system runs along the sciatic nerve.

A serious complication of superficial or deep venous insufficiency is the development of chronic venous hypertension in the lower limb resulting in venous ulceration. If there is too much pressure on the lower extremity veins this is where more blood can be stored and therefore chance of excessive pressure and eventually varicosities. Risk factors associated with ulceration include post thrombotic syndrome obesity immobility and arthritic conditions which cause reduced movement of the ankle joint leading to failure of the calf muscle pump.

The superficial veins are located within the subcutaneous tissue whilst the deep veins are found deep to the deep fascia. The upper and lower extremity peripheral venous systems comprise three main types of veinssuperficial deep and perforating. At the region of the sfj in the gsv because a bunch of tiny superficial tributary veins confluence with the gsv.

It travels up the leg in front of the inner ankle protruberance anterior to the medial malleolus and ascends all the way up the lower limb on the inner aspect leg and thigh anteromedial aspect. The venous system of the lower extremities includes the deep veins which lie beneath the muscular fascia and drain the lower extremity muscles. There are as much as 150 perforating veins pvs in the lower extremity.

The superficial and deep subsystems are defined by major and tributary veins linked by the perforating veins as well as venous networks plexi with the goal of directing all venous blood return into the deep system in peripheral mid or central extremity venous segments. The deep and superficial venous systems and perforator veins. The lower limb consists of two main types of veins.
