High Vienna: Anatomy, function and meaning.

  Articles

thighs of big blood vessels, the femoral vein is the main way in which the blood of the lower extremities moves towards the heart. Sometimes they call the femoral vein of the surface (unlike deep femoral veins).

This is a conjugated container, which means that it is in both legs, is the main supplier of the deep thigh, which makes it critical for the lower extremity and function of the function.

Top-Wedlan Vein Located behind the knee and with the blood of two tibial veins on the lower leg, it continues in the femoral vein on the hip, which continues in the general femur on the upper thigh.Blood blood passes through the outer vein of toy in the pelvis. / P>

Given its location and function, doctors can use the top of the femur vein for catheterization, The means of diagnosis and treatment some cardiovascular conditions.The rise of the femoral veins is called deep vein thrombosis (DVT) can cause significant symptoms, as well as pulmonary embolism (lungs and clutch).

Anatomy

Structure

BETWEEN BORTS OF BIG BOATING,The diameter of the adult femur fluctuates from about 12 millimeters to 14 millimeters (mm), which is about half the inches. .

Like all ships in the body, the femoral vein consists of three cells of cells:

  • tunica intimate – Internal Vienna lining .This consists of a squamous epithelium, a semipermeable layer of cells, as well as the connective tissue.
  • Tunica Media is a relatively thick average layer that consists of smooth muscles that can be pressed to help press the blood.
  • , the outer lining, consists of various amounts of elastic and hard fibers. These are forming a vein and help keep it in place.

Location

Mentioned, the form of the femoral vein after the vein of the population ends with the back of the knee and passes to the hiatus adductor,What is a hole between muscle muscles of the Magnus adductor of the internal thigh and femoral bone.

Then, pass through the front (front part) of the thigh, up and to the center of the body along the slot is called the Adductor channel. Throughout this course, it becomes the femoral disaster triangle, depression between the muscles of the thigh, where the femoral vein runs next to the femorial arteria , the main blood supplier At the lower extremities.

The beech shell is crossed, the funnel-shaped space that connects the lower part of the abdomen and the femoral triangle.Then, the femoral vein ceases and becomes an olok outer vein, just behind the groin link, a tight band of the tissue, which forms a barrier between the thigh and the pelvis. It rises and medial (to the center of the body) through the thigh.These are:

  • deep femoral : is a boat, another big thigh vein, access to the back of the femoral vein is about 8 centimeters (only more than 3 inches) from the Groove beam.
  • Great subdeferencing Vein : Body, the largest vein, this container passes from the legs to the hips through the subcutaneous cell under the skin from the bottom of the leg.It joins the femoral Vienna in the front, not far from the pelvis.
  • Cistrix Weens Fishoral : The lateral and medial circumferential femoral thighs are connected to the corresponding hips,What are the branches of the deep femoral artery of the rejection legs

Anatomical variations

In general terms, congenital anatomical variations of femoral veins are relatively common.The most common include:

  • Duplicate femoral vein is the most common anomaly in which the new parallel femoral veins pass along with the original.
  • Ac Fishoral The trunk is the case in which the femur vein is not fully formed, which makes the axial vein of the main Vienna of the thigh.
  • Poor poor trunk occurs when the lack of development of the femoral vein leads to the fact that deep femoral vein is a primary path for blood, leaving the lower extremities.

In many cases, doctors find differences between the structure of the veins on the left and right hips.

Function function

The veins take deoxygenized blood (blood, oxygen exhausted after absorption by cells) back to the right side of the heart.The right side of the heart carries this blood easier so that blood can become an oxygen. Then, oxygenated blood moves towards the left side of the heart, and the left side of the heart pumped oxygenated blood to the body.

As primary deep thigh vein, the femoral vein is crucial to drain the blood from the lower extremity.In particular, after connecting with a crown of , the femoral vein carries blood from the part of the foot and the back of the lower part of the leg.A along the course, also deoxy blood From the muscles of the hips.

Clinical value

For your greatest, in the hospital and medical care, femoral veins can be used in a couple of important procedures, and you can participate in some health conditions ,breakdown quickly:

Cateterization

In this procedure, a small tube goes to Through a femoral vein to access access to the right atrium of the heart, where it can measure blood pressure and oxygen levels.It is used more frequently to diagnose and treat certain cardiovascular states, such as heart failure and coronary artery .

Sample venous

is used as a means for assembling vein fabric samples for testing and evaluation, this procedure helps doctors diagnose certain hormonal conditions or diseases,Like the pillow syndrome , aldosteroneism (tire of high blood pressure) and hyperthyroidism , among other things. The Vienna conversation can serve as an access point for the tools that are entrusted to drop this tissue.

Deep vein thrombosis

DVT is A potentially dangerous state in which blood clots are formed in a deep vein.They are often found in the lowest veins of the extremities, such as the femoral vein, the DVT becomes especially serious if they turn off with minimum materials and reach the lung (condition called .

Not only does it lead to swelling, pain and tenderness, if you progress, TVP can cause respiratory difficulties, high or irregular heartbeat, head of light and cough. These symptoms require emergency medical attention.
