Portwine stainhttps://en.wikipedia.org/wiki/Port-wine_stain
Ko te Portwine stain he paheketanga o te kiri o te tangata i puta mai i te heenga o te kapi i te kiri (capillary malformation). He penei te whakaingoatia mo ō rātou tae, he rite te tae ki te waina tauranga, he waina whero nō Potukara. Ko te portwine stain he heenga kapi, ka kitea i te whanautanga. Ka mau tonu te portwine stain puta noa i te ao. Ko te wāhi o te kiri kua pā ki te tipu ka rite ki te tipu whānui.

Ka puta te portwine stain ki runga i te mata engari ka puta ki ngā wāhi katoa o te tinana, otirā ki te kōpū, ki runga katua, ki ngā ringa me ngā waewae. I te nuinga o te wā he papatahi me te māwhero te āhua o ngā stains mōata. Ka pakeke te tamaiti, ka hōhonu te tae ki te tae whero pouri, ki te tae papura rānei. I roto i te pakeketanga, ka taea te whakapakeke o te whiu, te whanaketanga rānei o ngā kapia iti.

Maimoatanga
He āhua whai hua ngā laser vascular (vascular lasers), engari me utu ngā taputapu laser me te maimoatanga (laser therapy) mō te wā roa mō ētahi tau. I te wā e pupuhi ana ngā whiu i te pakeke, ka iti ake te whai hua o te maimoatanga laser, he raru pea. Pink lesions (pink lesions) he uaua ake ki te rongoa atu i ngā red lesions (red lesions) nā te mea kua hōhonu te kiko o te toto.
#Dye laser (e.g. V‑beam)
☆ I te 2022 Stiftung Warentest hua mai i Tiamana, he iti noa iho te pai o nga kaihoko ki a ModelDerm i nga korero mo te waea rongoa utu.
  • Portwine stain ka taea te rongoa ki te laser, engari he utu nui me te pau te wa.

    Ko te Flash‑lamp pulsed dye laser (FPDL) kua mohiotia inaianei ko te laser tino tika e waatea ana mō te rongoā i ngā take toto taumata‑mata. I roto i tēnei rangahau, i kohia e mātou ngā raraunga mō te tekau tau o te wheako ki te whakamahi i te maimoatanga taiaho wai‑kano mō ngā turoro he maha ngā momo mate toto (telangiectasia, rhinophyma, port‑wine stains, cherry and spider angiomas, and vascular tumors such as cherry angiomas, infantile hemangiomas, port wine stains, rhinophyma, spider angiomas, and telangiectasia).
    The Flash‐lamp pulsed dye laser (FPDL) is nowadays considered the most precise laser currently on the market for treating superficial vascular lesions. In this study, we gathered data from 10 years of experience regarding dye laser treatment of patients presenting vascular malformations such as telangiectasia, rhinophyma, port‐wine stain, cherry and spider angioma and vascular tumours: cherry angioma, infantile haemangioma, port wine stain, rhinophyma, spider angioma, telangiectasia

    Ko Port-wine stain (PWS) e mohiotia ana ko nevus flammeus. He papaki mawhero, whero ranei i runga i te kiri o te peepi na nga oko toto rerekee. Ka kitea i te wā i whānau ana, ka noho tonu mo te ora, ka puta ki te kanohi. He mea nui ki te wehewehe mai i te nevus simplex, i te papaa paramanawa ranei, ka memenga i te wā.
    Nevus flammeus or port-wine stain (PWS) is a non-neoplastic congenital dermal capillary hamartomatous malformation presenting as a pink or red patch on a newborn's skin. It is a congenital skin condition that can affect any part of the body and persists throughout life. The nevus flammeus is a well-defined, often unilateral, bilateral, or centrally positioned pink to red patch that appears on the face at birth and is made up of distorted capillary-like vessels. It needs to be differentiated from a nevus simplex/salmon patch, which is usually seen along the midline and disappears over time. An acquired port-wine stain, clinically and histopathologically indistinguishable from congenital capillary malformation, has been reported to develop in adolescents or adults, usually following trauma.

    He mea nui te rongoa i te PWS hei whakaiti i te paanga ki te hauora hinengaro me te whakaheke i te nodularity me te whakarahi kiko. Ko te tiimata wawe ki te maimoatanga ka pai ake nga hua. Ko te Pulsed dye laser (PDL) ka whakaarohia ko te whiringa pai rawa atu mo nga momo PWS katoa, ahakoa te rahi, kei hea, me te tae.
    Treatment of PWB is indicated to minimize psychosocial impact and diminish nodularity, and potentially tissue hypertrophy. Better outcomes may be attained if treatments are started at an earlier age. In the United States, pulsed dye laser (PDL) is the gold standard for all PWB regardless of the lesion size, location, or color. When performed by experienced physicians, laser treatment can be performed safely on patients of all ages. The choice of using general anesthesia in young patients is a complex decision which must be considered on a case by case basis.
