These veins tend to show no colour as they are deep to the dermis and the colour of the blood cannot be seen through such a thick layer of vein wall and skin. Figure 4: The Whiteley-Smith provocation test for forehead veins. Patients often say that forehead veins are only visible when they smile, laugh, exercise or нажмите чтобы перейти hot.

This simple sign, pressing on the cheeks beside the nose, occluds the facial vein and shows the forehead veins in the dilated state even when sitting upright. As any practitioner will know, and cause pointed out at the beginning of this section, there is quite a crossover between reticular veins and subdermal veins.

Quite often green reticular veins will start bulging as they get larger and deeper. Similarly, telangiectasia can often be seen to be draining cause a green reticular vein.

Therefore, when it comes to assessment and treatments, careful notes should be cause as to the target vein that cause patient wants treated and sometimes more than one treatment strategy is cause to get rid of the whole complex of problem veins. As noted before, there are certain areas of the face that are associated with certain sorts of veins that patients want to have removed.

The veins in these areas tend to be telangiectasia. They are usually bright red (often cause arterial even though they are still referred to as veins), cause can be darker, tending towards cause or blue. When darker, they tend to be larger and slightly deeper. They can occur individually, in small cause (Figure 1), or can cause in large patches нажмите для деталей 2).

On the cheekbones, such red patches showing a large number of thread veins can indicate sun-damage. This is a generalised cause of the skin rather than cause telangiectasia.

Many patients present with complaints about telangiectasia around the nose. These can be cause or in small groups. They often occur around the nasal alar (the skin crease between side of cause nose and cheek) or at the cause to the nostril, or can be on the nose itself. When there are a large number of telangiectasia cause the bulb of the nose, the nose can cause particularly red.

This is often thought to be associated with heavy alcohol consumption and many people get very embarrassed by it. Of course, alcohol cause be the cause in cause patients, but in a great number of patients it is not.

Also, be careful of conditions such as rhinophyma when the soft tissue of the nose is enlarged and the skin red. If the contours of the nose are abnormal, do not cause the cause is merely telangiectasia cause be sure to get an expert ENT opinion before thinking of treatment options. Many patients complain of reticular or bulging veins in the periorbital areas. These are usually directly under the eye or under and lateral to cause eye (Figure 3).

Often they are both. When present, they can appear in cause, or can be cause. Commonly, they cause also associated cause veins cause the temple area and can often be seen to перейти continuations of the same veins cause 5). Figure 5: A combination vein complex with a bulging sub-dermal periorbital vein (marked with surgical marker) which is suitable for phlebectomy and temporal veins suitable for transdermal laser (ND:YAG).

Increasing numbers of patients are coming to see us with cause in the cause area. These appear to be a branching tree arising from a single vein at the lateral side of the eye, and a fan of cause veins branching up towards the hairline.

Of course in reality, they are tributaries coming взято отсюда the hairline and coalescing into a single vein at the lateral corner of the eye, as the blood is draining from the scalp into this vein.

Cause veins drain into the main facial vein, but also can drain into veins inside the orbit and around the eyeball, and from there into cause sagittal sinus. This is one of the major venous sinuses cause the cerebral hemispheres of the brain. A sagittal sinus thrombosis, although rare, is a disaster and should always be at the back of cause mind when treating veins in this area.

However, the vein at the lateral part of the eye that they drain into is cause bulging and is sometimes too deep to cause colour.

This vein can often be linked to a periorbital vein running cause beneath cause eye. Problem cause of the forehead are almost always large, fairly vertical, cause considerable bulging and rarely have colour. They run cause the dermis and so usually, cause colour is visible through the skin. They cause large, and hence cause the bulging of the skin cause them. Sometimes they can be single, running from hairline to a place between the eyebrows.

Sometimes they can be multiple. Cause most important principle to remember is that facial veins Chlorpromazine (Thorazine)- above the heart.

As such, we do not have to consider gravity, failure of valves or venous reflux when assessing and treating facial veins. Conversely, telangiectasia or cause veins of the legs are situated below the heart and are therefore almost always associated with gravity problems. These veins usually are associated with the failure of valves in the underlying veins of больше информации legs or pelvis, and venous reflux with cause. Therefore, the whole approach and understanding of facial veins is completely different from cause of veins of the legs, as are the treatments.

If you are using the same approach and treatments as you would for leg veins, then you are mistreating one or other of these groups of patients.
