Venous lake of the lip treated with a sclerosing agent: report of two cases

A Novel Air-Cooled Nd:YAG Laser for the Treatment of the Venous Lakes of the Lips

Objective: To evaluate the therapeutic effect of a novel air-cooled Nd:YAG laser in the venous lakes of the lips (VLL). Background: The thermal injury is one of the most important issues during laser therapy for venous lakes. Methods: Six pieces of fresh pork livers were used to provide 30 regions with a diameter of 6 mm for experiment in vitro, among which 15 regions were treated by Nd:YAG laser with air cooling until the tissue turned gray-white, whereas the rest were treated without air cooling as control. The operation time of laser irradiation, the degree of temperature increase, and the depth of coagulation tissue were compared between two groups. Then, 60 VLL patients were selected for Nd:YAG laser treatment with or without air cooling. The operation time of laser irradiation, the degree of temperature increase, the postoperative pain visual analog scale (VAS) score, and the percentage of lesions removed within 1 month were compared. Results: In tissue studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and there was no significant statistical difference in the depth of coagulation tissue (p = 0.624). In clinical studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and a lower VAS score on the 1st and 2nd day, compared with the control group (p < 0.01). Conclusions: Air cooling during Nd:YAG laser for the treatment of VLL can prolong the surgical time, but lowered tissue temperature and reduced patient pain within 2 days under the premise of ensuring the treatment effect.

Laser and light-based treatments of venous lakes: a literature review

Venous lake is a benign vascular malformation commonly seen in elderly patients, typically arising in sun-exposed areas of the body. Patients often seek treatment to prevent recurrent bleeding or because they find the lesion cosmetically unacceptable. Venous lake may negatively affect quality of life, due to the cosmetic disfigurement it can create and the resulting psychological distress. Traditional treatments, such as surgical excision, cryosurgery, sclerotherapy, and electrocoagulation, result in varying degrees of success and can cause discomfort. Laser- and light-based treatment modalities may offer a safe and effective alternative, as numerous studies have shown their benefit in the treatment of venous lakes, particularly with the long-pulsed 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG). Although various types of lasers and lights have been studied, there remains a lack of general consensus as to which one is the superior laser modality. Further studies that establish standardized protocols to compare the results of using different types of laser treatments are warranted.

Successful Management of Lip and Oral Venous Varices by Photocoagulation with Nd:YAG Laser

AIM

This study assessed the effectiveness of photocoagulation with Nd:YAG laser in the treatment of lip and oral venous varices.

MATERIALS AND METHODS

Sixteen consecutive patients (eight men and eight women, mean age 56 years) diagnosed as having either lip or oral venous varices, were examined and treated with a noncontact Nd:YAG laser. As lesions were small (less than 1 cm), round or oval in shape, flat, dark to blue in color and symptomless, patients sought for treatment either for esthetic reason, bleeding or cancerophobia-related concern.

RESULTS

All but one lesion were successfully treated with only one irradiation exposure. Healing was completed in about 2 to 4 weeks; none of the patients experienced complications or recurrence. Pain was out of any major concern during immediate follow-up.

CONCLUSION

Although photocoagulation with Nd:YAG laser did not outperform the effectiveness observed with diode laser (data shown in a previous study),(17) it proved to be safe and effective for the treatment of lip and oral varices, with consistent results.

CLINICAL SIGNIFICANCE

Most of patients with oral and lip varices only need some clinical advice regarding the their nature of their lesions. Yet, for those who seek treatment for this conditions, the use Nd:YAG laser is an option as it yields satisfactory outcomes.

Hemangioma: review of literature

Hemangiomas are tumors identifed by rapid endothelial cell proliferation in early infancy, followed by involution over time. All other abnormalities are malformations resulting from anomalous development of vascular plexuses. The malformations have a normal endothelial cell growth cycle that affects the veins, the capillaries or the lymphatics and they do not involute. Hemangiomas are the most common tumors of infancy and are characterized by a proliferating and involuting phase. They are seen more commonly in whites than in blacks, more in females than in males in a ratio of 3:1.

Venous lake of the lips treated using photocoagulation with high-intensity diode laser

OBJECTIVE

To evaluate the effectiveness of photocoagulation with high-intensity diode laser in the treatment of venous lake (VL) lesions.

BACKGROUND DATA

VL is a common vascular lesion characterized by elevated, usually dome-shaped papules, ranging in color from dark blue to dark purple, seen more frequently in elderly patients. They often occur as single lesions on the ears, face, lips, or neck. Once formed, lesions persist throughout life. Although these lesions are usually asymptomatic, they can bleed if injured.

METHODS

Seventeen patients (7 men and 10 women) with VL on the lip were treated using a noncontact diode laser (wavelength 808 nm, power output 2-3 W in continuous wave).

RESULTS

After only one irradiation exposure, all lesions were successfully treated. Healing was completed in approximately 2 to 3 weeks, and none of the patients experienced complications. Postoperative discomfort and scarring were not present or were minimal.

CONCLUSION

Photocoagulation with high-intensity diode laser is an effective, bloodless procedure for the treatment of VL.

The Effect of 0.5% Sodium Tetradecyl Sulfate on a Venous Lake Lesion

BACKGROUND

A venous lake lesion is a venous ectasia that occurs on the exposed skin of elderly people. Although a number of therapies such as surgical excision, laser therapy, infrared coagulation, cryotherapy and sclerotherapy have been used to treat venous lakes, there is no guideline for treating this lesion.

OBJECTIVE

The purpose of this study was to determine whether 0.5% sodium tetradecyl sulfate (STS) is effective for the treatment of venous lake lesions.

METHODS

Twelve patients with venous lake lesions were enrolled In this study. After proper antiseptic preparation, 0.5% STS was slowly injected into each subject's lesion, and this was followed by immediate compression for 10 minutes.

RESULTS

After treatment, all of the patients' lesions cleared completely. The average number of treatments was 2.15±1.28. Two patients experienced mild side effects such as light pain and paresthesia, and these soon disappeared. There were no serious side effects reported during treatment. The mean follow up period was 29.58±13.48 months.

CONCLUSION

We have demonstrated that sclerotherapy with 0.5% STS was quite effective for treating venous lake lesions, and this treatment caused no serious adverse effects.

Long-pulsed Nd:YAG laser treatment of venous lakes: report of a series of 34 cases

BACKGROUND

Some venous lakes do not respond well to traditional vascular lasers. The Nd:YAG laser output at 1,064 nm is less well absorbed by hemoglobin but penetrates more deeply into tissue.

OBJECTIVE

This study was undertaken to assess the effectiveness of the long-pulsed Nd:YAG on venous lakes.

METHODS

Thirty-five consecutive adult patients presenting with a venous lake were studied. Four patients had failed to respond to polidocanol 1% sclerotherapy, and 1 patient to pulsed dye laser. Long-pulsed Nd:YAG was administered via a water-cooled tip. Either a 3-mm spot at 250 J/cm(2) and 55 ms or a 5-mm spot at 140 to 180 J/cm(2) was used depending on the size of the lesion. Clinical end points were characterized by hardening of the lesion, central blackening, minimal whitening of the periphery, and in most cases, an audible popping sound. Responses were assessed visually in 50% of cases or by phone contact in the remaining 50% if the lesion had completely disappeared. One patient was lost to follow-up.

RESULTS

After a single treatment, 94% cleared completely; incomplete clearance occurred in 6%. There were no reported complications.

CONCLUSIONS

The long-pulsed Nd:YAG laser is highly effective treatment for venous lakes of the lip and cheeks.
