Diode laser and surgical treatment of giant cavernous hemangioma of the body surface

PURPOSE : 
The efficacy of Diode laser and surgical treatment of giant cavernous hemangioma of the body surface

METHODS: 
2005 ~ 2007, 18 cases of giant cavernous hemangioma of the body surface were treated. First fiber optic percutaneous insertion of vascular tumors and the outer edge of the deep burning, pressure bandage to be tumor thrombosis after surgery.

RESULTS: 
18 cases were cured and no recurrence during follow-up

CONCLUSION: 
Laser and surgical treatment of giant hemangioma of the bodysurface, less bleeding, recurrence rate is low, less complications and curative effect for the treatment of cavernous hemangioma provides a new way.

[Key words] Diode ; laser; Hemangioma; cavernous; thrombosis

Body surface hemangioma is a congenital vascular malformation. That the existence of the disease at birth, growth and expansion of age. The clinical surgery, laser, injection sclerotherapy, frozen and other treatment. Cavernous hemangioma lesion a wide range of rich blood supply, blood vessels tortuous thin wall, surgical separation easy bleeding. Radical surgery can achieve results, but part of the giant hemangioma, often due to blood loss volume, and the surrounding ill-defined but not removed completely, bleeding, skin flap necrosis and other complications occurred and postoperative recovery fat chance of a larger. Laser Treatment of Superficial Hemangioma alone although trauma, no incision scar, but because of their often cause local aseptic inflammation, thrombosis and its surrounding adhesions, there
subcutaneous induration, pain, does not apply to large hemangioma, and the high recurrence rate. In recent years, our department applied laser and surgical treatment of giant hemangioma surface made remarkable curative effect, the information will now be summarized as follows.


1 Clinical
1.1 General Information: April 2005 ~ May 2007, with laser and surgical treatment of giant cavernous hemangioma of the body surface in 18 cases, 8 males and 10 females, aged from 20 to 65 years old. Lesions, shoulder in 2 cases, 3 cases of abdominal wall, back in 3 cases, limbs in 7 cases, the hip in 2 cases, the perineum 1cases. 8 patients have been outside the hospital for 1 ~ 2 times surgery. 1 case had been sclerotherapy. Extent of the lesion 5 cm × 6
cm ~ 30 cm × 40 cm, an average of 10 cm × 13 cm.

1.2 Treatment Methods: Diode laser system 30W, wavelength 810nm, fiber diameter of 0. 6 mm, can be selected continuous or pulse output. According to lesion choose epidural, brachial plexus, or local anesthesia. Conventional disinfection shop towel, with 5 casing needle deep into the tumor, see the return of blood after the tumor deep into the fiber to 15 W / s power, while back side burning fiber. Laser adopt the "multi-point radial" puncture burning, to avoid harming the skin's surface and around the major nerves, tendons, or blood vessels. Intraoperative consuming 3 000 ~ 10 000 J. Postoperative local pressure dressing, hemostatic drugs used to promote thrombosis, applied 3 d of antibiotics to prevent infection. Most occur in patients with moderate fever, thrombosis due to consider. 5 d after the tumor shrink, harden, compressibility weakened. Surgical resection, patients can see a large number of bodiesfound in tumor thrombosis (confirmed by pathology), Bleeding decreasedm significantly
.
1.3 Results: 18 cases were stage Ⅰ, all been healed incision, no physical dysfunction, or bleeding and other complications after a follow-up to 36 months without recurrence.

2 Discussion
The Diode laser and surgical treatment of superficial cavernous hemangioma is the emiconductor laser into the tumor tissue, the laser can be vascular malformations in a large number of highly selective absorption of the reduced hemoglobin, while the other organizations to absorb very little, so the laser energy mainly in the lesion within the solar energy to heat means acting on the blood vessels within the cortex, resulting in selective destruction of the role of coagulation. In addition intravascular hemoglobin absorption of the laser, can cause intravascular thrombosis, blood vessel wall injury, vascular closure.
After pressure after 5 d, the promotion of thrombosis, significantly reduced the amount of surgical bleeding. After all, after two anesthesia,So, apply only to large hemangioma is estimated that surgical patients with large amount of bleeding. This paper reports 18 cases of the range, and distributed in various parts of the body surface of cavernous hemangioma, combined with laser surgery, has received satisfactory results.


This method requires attention to a few points, 
A. Do not burn the skin away from too close and easy to cause skin burns. 
B. To avoid the near important nerves and large blood vessels and tendons. 
C. Power is too low, incomplete vascular coagulation easy bleeding, power is too high, skin damage is too large. Typically 15 W / s. 
D. Attention to puncture the direction and strength, or else make the first break in the optical fiber within the hemangioma.

Leg Vein Laser Therapy

It is estimated that over half of the female population is affected by noticeable red, purple or blue veins, also known as spider veins, in the upper and lower areas of the legs. Spider veins are a cosmetic problem that many women face, but few realize there is a treatment for the veins. The Aesthetics Gallery offers laser treatments for leg veins. 

How Leg Vein Therapy Works

Spider veins are caused by a venous insufficiency syndrome, which allows blood in the veins to escape from normal blood flow. In women, the appearance of spider veins can be linked to such factors as heredity, weight gain, hormonal changes and prolonged sitting or standing. While mild forms are viewed as a cosmetic problem, spider veins are bothersome and can cause minor aching, burning and swelling.

The laser treatments involve a laser light that is directed through the skin into the vein by the Gemini laser. The heat causes the vein wall to collapse, seal shut, and then be absorbed by the body.

The Procedure: Laser Treatment

The laser treatment usually takes approximately 30 minutes; however, it may vary depending on the size of the treatment area. While each patient’s discomfort level varies depending on the size and location of the vein, an anesthetic cream is used to minimize any pain.

What to Expect

After the laser treatment, swelling and tenderness may occur for a day or two, but there is no recovery time for laser therapy. A red mark that resembles a scratch may appear near the treated area, but usually fades within a month. This procedure generally requires one to three treatments, which may be performed every eight weeks.

Response of spider leg veins to pulsed diode laser (810 nm)

 BACKGROUND:

Spider leg veins arecommon. Their treatment with laser or intensed light therapy shows generally variable success rates and often adverse side effects such ashyper- or hypopigmentation. This study was performed to investigate whether pulsed diode laser (810 nm)treatment is effective and safe.

METHODS:

Thirty-five female patientswith spider leg veins were includedin this prospective trial. They were treated twice with a pulsed diodelaser (810 nm). Laser therapy was performed on day 0 and day 14. Clinical assessments were before an carried out immediately after the first laser therapy, after 2 weeks, 8weeks, and one year. Skin biopsies were taken before and immediately after the first laser treatment, and after 10 weeks. Contact-free remittance spectroscopy was performed before laser treatment, immediately after the first treatment, after 2weeks and 8 weeks.

RESULTS: After the first treatment 15patients showed a complete disappearance(CR); in the remaining 20 patients a remarkable improvement (RI) was noted (n~35). After six months of follow-up CR was seen in 6 patients, RI in 6, a stable situationin 9, and scar formation in 1 patient(n~21). The effect was almost completely stable during one year offollow-up. The examination of histologicalspecimens before and afterlaser treatment showed no cellularin flammatory reaction. The mean vascular area was significantly reduced after the first (p,0.05) and after the second (p,0.05) laser treatment. Spectral analysis showed a marked decrease of peaks for oxygenized haemoglobin immediately after laser treatment and during thefollow-up. Safety profile was excellent without purpuric reaction orpigmentary changes. Mild scarringwas observed in two patients at theend of follow-up.

CONCLUSIONS:

Pulsed diode laser therapy (810 nm) is an effective and safe treatment option for spider legveins. The effects can be seen immediately.Objective monitoring by non-invasive remission spectroscopy and histology of biopsy specimens demonstrates selectivity of the laser action.

Diode Laser for Treatment of Onychomycosis

Onychomycosis is a common infection of the nail and affects approximately 6% of the adult population. It affects immunocompromised individuals (ie HIV positive patients), smokers and patients with psoriasis, peripheral vascular diseases or patients having suffered a traumatic to the nails. Pathogenic agents causing the occurrence of onychomycosis are numerous and varied different forms of Trichophyton, Epidermophyton floccosum, but also mold and yeast. 

The treatment of onychomycosis is hard because the infection is located in the fingernail, over an area difficult to achieve. Complete removal of symptoms is slow and may take more than one year. Several oral and topical therapies have been used in the past to treat onychomycosis. Topical therapies, such as potassium permanganate, has been the main method of treatment, until systemic antifungal new treatments have been developed. 
These antifungal therapies, such as itraconazole and terbinafine, have not only modest clinical success, but may also have common side effects, such as headaches, gastrointestinal and cutaneous disorders. 
A new concept for non-invasive treatment of onychomycosis is irradiation in a specific area with a laser beam, whose wavelength is absorbed by the pathogens. The absorbed energy is converted into heat, and the temperature increase which follows heat disables the pathogenic microorganisms, without damaging the surrounding tissue. 
The specific wavelength used by 980nm diode laser has the effect of disabling the parasitic organism. Moreover, the duration of pulses applied, about ms, is less than the thermal relaxation of the skin (about 10 ms). That will allow the containment of thermal absorbed energy, in order to make the treatment painless. Such a device is used together with an optical fiber and a handpiece, issuing a beam of a 6mm diameter in order to maximize the processing performance. 

The protocol for treatment of onychomycosis consists of three treatments performed the day 1, day of the first treatment, followed by two additional treatments after 30 and 60 days. During each treatment about 700J/cm2 are released by the pulses with a peak power of 30 W and a duration of 2 msec. The success rate is approximately 70%. 

Benefits of this technology are numerous: 
- Infrared radiation has no risk of teratogenicity, unlike the ultraviolet; 
- No medications are required for the therapy, unlike photodynamic therapy (PDT - Photodynamic Therapy); 
- No toxic fumes related to the laser ablation of typical pulse lasers, such as Nd: YAG laser; 
- No side effects or complications; 
- The action that the laser performs acts on bacteria and fungus without damaging healthy tissue, as the temperature at which the nail is brought with treatment parameters tested, brings the temperature to about 42 ° C , a temperature required to kill bacteria or fungi, without affecting healthy tissue; 
- The treatment is painless.

Hemorrhoids Laser Treatment

Hemorrhoids can get extremely painful causing serious health problems. And this is when hemorrhoids laser treatment can come to your rescue. Here we give you the advantages of hemorrhoids laser surgery, besides the procedure.


Hemorrhoids also called piles are a swelling of the veins of the annal and rectum areas. These swollen veins may burst due to excessive pressure, thereby resulting in the presence of blood in stool. Initially the condition shows signs of hemorrhoids itching and pain of the rectum, which if not taken care of may result in bleeding. Bleeding hemorrhoids may result from lifting heavy objects, severe coughing and hard stools. Depending on how severe the condition is, hemorrhoids can be classified into four degrees - first, second, third and fourth degree hemorrhoids. In the first degree hemorrhoids, there's bleeding without prolapsing and it's usually a condition called internal hemorrhoids. In the second degree hemorrhoids, the tissues prolapse, but they return to normal spontaneously. In the third degree hemorrhoids, you need to manually place the tissues after prolapsing, while in the fourth degree hemorrhoids the prolapsed tissues can't be manually replaced and they may require surgery. Surgery may be required for any of these stages depending on your health conditions. There are different types of surgeries, and laser surgery is one. Hemorrhoids laser treatment have become one of the most popular options to get rid of this condition. There are several advantages and disadvantages of going through laser surgery, which are mentioned in the paragraphs that follow.

Laser Treatment for Hemorrhoids

The doctor would carry out necessary tests and see how severe your condition is before taking a decision whether surgery is required or not. Initially the professional may recommend medications which may get you rid of external hemorrhoids. However, if it's not cured, you may need to go through a laser surgery. There are several things like place of the hemorrhoids, duration for which it has been present and symptoms of the condition, that are considered before taking a decision whether to remove it by surgery.

In the last few years, hemorrhoids laser surgery has been successfully used for healing hemorrhoids. In this process, laser beams are used which destroy the hemorrhoids. Laser beams help in numbing and making the tissues insensitive, after which the excess tissues are removed. During the course of the surgery there's no bleeding or incision involved, which makes it comfortable for the patient. At times there may be discomfort and pain associated with this procedure, but then that's less in relation to other surgical methods. 

If you decide to get laser treatment for hemorrhoids, you need to look at the pros and cons of it. One of the most important advantages of this treatment is that the chances of damaging the surrounding tissues are very less. As such there are no chances of any complications arising later on. As there is no question of incision of blood vessels, there is no loss of blood. Unlike other surgical methods, there is no pain associated with this procedure and as such the time required for recovery is less. And the best part is, you don't need to stay in the hospital for long periods. Additionally, you can get back to normal day-to-day activities within a few days.

After reading about the laser treatment dedicated to hemorrhoids, you must have realized that hemorrhoid laser surgery is one of the best options available to get rid of hemorrhoids. But then it would depend on how severe your condition is. Surgery can be a costly option and so it's better to first try alternative remedies if possible. As with all medical conditions, the doctor knows best, so consult one before taking a decision.
