First, treatment
Vulvar capillary hemangiomas can be self-controlled or regress over time without active treatment. If it does not regress within a few months, cryotherapy or local radiotherapy can be adopted, or appropriate treatment methods can be selected according to different types and specific clinical conditions. For hemangiomas during the infant period, especially strawberry-like hemangiomas or cavernous hemangiomas, treatment can be temporarily withheld, and observe for several years. If it still does not regress, appropriate treatment methods can be chosen as follows.
1. Hardening agent injection
Suitable for small strawberry-like hemangiomas, cavernous hemangiomas, or mixed hemangiomas. The syringe is inserted into the tumor, and after pulling back without blood, the drug is injected into the base of the hemangioma. Inject once a week or every other week, the injection volume depends on the size of the tumor. Generally, it takes several times to see the effect. The following commonly used drugs can be chosen:
(1) 5% Sodium liver oil solution mixed with 2% lidocaine can be mixed in equal volumes.
(2) Anhydrous ethanol or 95% ethanol.
(3) 15% to 10% Salicylate solution.
(4) Quinine-Ural injection.
(5) Xiaozhi Ling Injection mixed with 1% to 2% procaine in a 1:1 to 2:1 ratio.
(6) Pingyangmycin (Bleomycin A5): 8mg dissolved and diluted with 2% lidocaine, the dose per time should not exceed 8mg.
(7) 9ml of 40% urea physiological saline and 1ml of lidocaine, the injection volume depends on the size of the tumor.
(8) Xiaoxing Injection: 250g Dahuang, 25g Mingfan, 100ml each of propylene glycol and glycerin (propylene glycol), 25ml benzyl alcohol, 150ml ethanol, water added to 1000ml. Administer 2-6ml each time, once a week, with 4 times as one course of treatment, for the treatment of cavernous hemangiomas.
2. Glucocorticoid hormone therapy
(1) Triamcinolone acetonide (Acetate of Triamcinolone Acetonide) injection is used for intradermal injection therapy for strawberry hemangiomas. The dose is determined by the size of the lesion, usually 10mg per session, once a week, with 5 sessions as one course.
(2) For children with rapidly growing strawberry hemangiomas, systemic application of glucocorticoid drugs such as prednisone (20-40mg/d) can be used, with continuous treatment for 1-3 months, which can reduce the size of the hemangioma.
3. Surgical resection
It is suitable for large cavernous hemangiomas.
4. Radiation therapy
(1) Radioactive isotope 90Sr dressing can be used for port-wine stains and strawberry hemangiomas. The conventional treatment dose of 90Sr dressing is 1.5-2Gy per session, once a day, with 7 sessions as one course, and the total dose is 10.5-14Gy. If not cured, another course can be administered after two courses. Some people also use high-dose 90Sr dressing therapy, with each person receiving 6.5-8.5Gy, once a week, with 3-7 sessions as one course, and the interval between courses is 2 months, with a total dose of 14-34Gy.
(2) Radioactive isotope 32P specialized dressing can be used to treat strawberry hemangiomas. The dose used each time is calculated by 37X104Bg (10mci) per square centimeter of tissue. If the condition is not cured in one session, the dressing can be reapplied after 3 months, but it is not recommended to exceed 3 times. Generally, those under 5 years of age are more sensitive.
(3) Colloid 32P injection is suitable for cavernous hemangiomas. The total dose is calculated by using 37X104Bg (10mCi) of colloid 32P per cubic centimeter of tissue. The single dose for adults should not exceed 3.7X107Bg (1mCi), and for children, it should not exceed 1.1X107Bg (0.3mCi). It is not suitable for 6-month-old infants. If the tumor is large, it can be divided into sections and injected in stages, with an interval of 3 months between each injection.
(4) X-ray irradiation: X-ray can be used for the treatment of port-wine stains, with each session of 800-1000R, irradiated once every 2-3 months, a total of 6-7 sessions, with the total dose not exceeding 6000R as preferred. If there is no significant improvement after 3-4 sessions of treatment, it indicates low sensitivity to X-ray, and further treatment is not necessary. This therapy is painless and suitable for treating children. For strawberry hemangiomas and cavernous hemangiomas, X-rays with a tissue half-value layer equivalent to them should be used for irradiation, with each session of 100-200Rad, once or twice a week. Usually, after 600-800Rad of irradiation, the development of skin lesions can be controlled. At this point, treatment can be paused and observed. More than half of the hemangiomas can gradually regress, but some skin lesions may continue to expand after treatment, and a larger treatment dose is required (1000-1500Rad). Some people also use low-voltage short-distance X-ray therapy for hemangiomas, with the dose chosen according to the tumor size, ranging from 1000-1500Rad, completed in one session. A review after 3 months, and if not cured, a second course of treatment can be considered as appropriate, with a total dose not exceeding 3000Rad, with an overall effective rate of 95.5%, and no sequelae observed.
(5) Interventional Radiology: Use angiography machine, first puncture locally for angiography of tumor vessels, and then inject sclerosing agent after angiography.
5. Laser Therapy
Nd-YAG laser (wavelength 532nm), argon ion laser (488nm and 514.5nm), copper vapor laser (578nm), and other lasers have achieved good effects in the treatment of erythema simplex. Nd-YAG laser and argon ion laser can also be used for the treatment of strawberry hemangioma.
6. Photodynamic Therapy
Photosensitizer hematoporphyrin (HPD) or cancer porphyrin (PsD-007) is injected intravenously at a dose of 0.8~5mg/kg, then laser照射 (the selected output wavelengths are reported to be 514.5nm and 630nm), multiple spot irradiation once or in stages according to the area of skin lesions, spot area 1~50cm2, laser energy density 50~500J/cm2. This method has good therapeutic effects. Some people have compared the efficacy of photodynamic therapy using frequency-doubled YAG laser (output wavelength 532nm) and copper vapor laser (output wavelength 577nm) as light sources for the treatment of erythema simplex, and found that the efficacy of photodynamic therapy using copper vapor laser as a light source is significantly better than that using frequency-doubled YAG laser as a light source.
7. Liquid Nitrogen Cryotherapy
It can be used for strawberry hemangioma, but it is often difficult for children and their parents to accept it due to pain.
8. Constant Magnetic Field Therapy
Mixed hemangioma is treated by applying a neodymium iron boron water magnet with a surface magnetic field strength of 0.1~0.2T daily for 3 months to 1 year.
9. External Treatment of Traditional Chinese Medicine
Crystal ointment, Wumiao Huoxian ointment, or Jiuxiang Bug treatment can be used for strawberry hemangioma. Binghuang powder can be used to treat cavernous hemangioma.
II. Prognosis
About 63% of patients will regress or shrink spontaneously within 5 years.
