Dorsalis pedis artery: anatomy, function and meaning

  Articles

dorsalis pedis artery is the main source of blood supply at the foot. Continue as a continuation of A> the previous tibial artery , the blood vessel carries oxygenated blood to the dorsal surface (the upper part) with the foot.The weak artery dorsalis pedis of pulse can be a sign of basic blood circulation , such as peripheral artery disease (pad).

Anatomy

There are three main arteries on the legs that supply blood on the foot: the peroneo (high neck) of the artery, the rear tibial artery and the front of the Tibra arteries.The dorsalis artery pedis on the foot is the continuation of the anterior tibial artery on the leg. When the artery takes place through the ankle joint, it becomes the artery of dorsalis pedis.

The artery is sitting in the presence (above), running on the bones of the eyelashes , then towards the early foot (sole). It is located between the two tendons of the Digitorum Longus muscle extender.On the side of the foot, the dorsalis artery pedis of the branch in the dorsal metatarian arteries and the end are small dorsal digital arteries.

Anatomical artery options are not infrequent.A study showed nine variations in the anatomy of the artery, including the absence of artery. Another study found that ramification variations occur in almost 10% of the population.

Function

dorsalis Pedis The artery carries oxygenated blood on the leg. Adequate bloodstream is required for the legs to maintain adequate health and mobility.Reduced blood flow can cause complications, such as pain, ulceration, poor healing of wound or even loss of extremities.

Two muscles found in the dorsal captivity (upper part) of the HUSTUCIS extender and expanding the blood supply of BrevisEive.de Dorsalis Pedis Artery digitizers.Nervi on the leg plays a role in vasoconstrictions, a normal process that controls the distribution of blood throughout the body.

The dorsalis Film Hallery, when the doctor is reviewed for a peripheral artery disease.Low or missing pulse can indicate vascular diseases . For those who are with diabetes 2 type 2 , the pulse missing dorsalis pedis is the predictor of the main vascular results.

Clinical value

Plate (fatty tank) The building in the arteries can occur anywhere in the body.When fat deposits accumulate in the arteries, and the walls of blood vessels are injured, they make the walls jump.

Substances floating through the blood, such as fat, proteins and calcium, then get stuck in the walls, which makes the walls already grow.The arteries in the lower extremities are particularly prone to atherosclerosis , which can lead to a decrease in blood flow and cause tissue damage and organ.

Peripheral arterial disease (PAD) is the type of atherosclerosis. This happens in the arteries in the extremities. When these arteries are blocked, the leg muscles and the lower legs weaken and calm down.Type 2 diabetes is the most common cause of fingers and feet filling in the US. UU., Often as a result of the Board.

Pain or discomfort on the legs, legs. And your fingers are the symptoms of the common platform.Other symptoms include cold legs, whitening skin, infection and bonus of legs that do not heal.

People who smoke have diabetes, high blood pressure , high cholesterol , kidney disease , and over 50 years of age with an increased risk for the site.Black Americans are twice as often as white or Asian Americans who will be diagnosed with the coating. Shopping often have atherosclerosis in other parts of the body, too.

Diagnosis The pad is carried out by measuring blood pressure on the lower legs and comparing it with the aid of weapons. It is known as the ankle / shoulder index (ABI), the test is a standard to detect pillows.It can also be done also

volume recording (PVR), which measures changes in blood volume on your legs. This test can help determine where the blockages are located.Vascular ultrasound can be done to study blood circulation.

Board treatment

Left without treatment, the pad It can lead to a heart attack A> , kidney disease and amputation .Treatment for placement can include changes in lifestyle, for example, to stop smoking , change the diet, exercises, legs and skin care and walking circuit.The management of other health conditions that can contribute to a State is also important.

Medications can also be used to treat combined conditions, such as high blood pressure and high cholesterol.Pictures against quality can reduce the risk of heart attack or stroke and places (cyclostazole) can improve pedestrian availability.

When paying attention to lifestyle and medication is not enough, you may need additional intervention, such angiogram with endovascular intervention or Surgical bypass.

TerceCectomy

Athrechhecome is a procedure that uses a catheter to remove the field of the artery. The catheter is inserted into the artery through a small hole.It is done in the hospital or in the offices of the surgeons of the vessel. This is done in combination with angioplasty. Most of the time it is a surgical procedure of a day, which means that the patient can go home on the same day.

angioplasty

Another procedure used to treat the site is angioplasty .Human transient angioplasty includes placing a globe inside the artery to inflate it at the blocking point to allow blood to resume fluency. The envoy can be done in combination with angioplasty and includes the positioning of the headset in the artery to keep it open.

Once inside the lock, the balloon is inflated to push the document against the wall of the artery.After completing the balloon off and withdrawn. This time it is inserted into the stent if used. / P>

Bypass surgery omission

Bypass Surgery includes routing the blood around the obstructed artery, vaccinating a new form.The surgery is carried out within the framework of general anesthesia in the vascular surgeon of the hospital.

The surgeon makes a small incision in the artery and places the transcircuous, which is connected above and below the locking failure of the transplant is made of a synthetic vein or tube.People go from four to seven days at the hospital after the clip.> Enderterectomy athero closed is a surgical removal of the artery plate.In general, only two places that are done in the common femoral artery, near the groin, and in the carotid artery, on the neck. The surgery takes place at the hospital under the surgeon Anesthetic Regional Regional

The incision is made along the arteries where the lock is located. Babe is removed, and sometimes the part of the artery fighter is also eliminated.In the carotid artery, the bypass is used to temporarify the blood to the brain temporarily, while the process is carried out and then eliminated at the end of the procedure.People usually remain in the hospital for one or two days after the entertainment.
