Murebure ndende Nd: YAG Laser ikoreshwa mumitsi

Indwara ndende-1064 Nd: YAG laser yerekana ko ari uburyo bwiza bwo kuvura indwara ya hemangioma na malformation yimitsi itwara abarwayi buruhu rwijimye hamwe nibyiza byingenzi byo kuba umutekano, kwihanganira neza, bikoresha amafaranga menshi hamwe nigihe gito cyo hasi kandi ingaruka mbi nkeya.

Kuvura lazeri yo kuvura imitsi yimbere kandi yimbitse kimwe nibindi bikomere bitandukanye byamaraso bikomeje kuba kimwe mubisanzwe bikoreshwa na lazeri muri dermatology na phlebology.Mubyukuri, lazeri zahindutse uburyo bwo guhitamo ibimenyetso byavutse mu mitsi nka hemangioma hamwe na port-vino hamwe no kuvura neza rosacea.Urutonde rwibibyara bivuka kandi byavuzwe neza bivura neza hamwe na laseri bikomeje kwaguka kandi bisobanurwa nihame rya Photothermolysis yatoranijwe.Kubijyanye na sisitemu yihariye ya lazeri, intego igenewe ni oxyhemoglobine yo mu mitsi.

Mu kwibasira oxyhemoglobine, imbaraga zoherezwa kurukuta rwamato ruzengurutse.Kugeza ubu, 1064-nm Nd: YAG laser hamwe nibigaragara / hafi ya infragre (IR) ibikoresho byinshi byoroheje (IPL) byombi bitanga ibisubizo byiza.Itandukaniro nyamukuru, ariko, nuko Nd: laseri ya YAG irashobora kwinjira cyane kandi ikaba ikwiriye cyane kuvura imiyoboro minini, yimbitse nkimitsi yamaguru.Iyindi nyungu ya Nd: YAG laser ni coefficient yayo yo hasi ya melanin.Hamwe na coeffisente yo hasi ya melanin, nta mpungenge nke zangiza ibyorezo byanduye bityo birashobora gukoreshwa neza mukuvura abarwayi bafite umwijima mwinshi.Ibyago byo kwanduza hyper pigmentation nyuma birashobora kugabanywa nibikoresho bikonjesha epidermal.Gukonjesha Epidermal ni ngombwa kurinda ibyangiritse biturutse ku kwinjiza melanin.

Kuvura amaguru ni kimwe mubisanzwe bisabwa kwisiga.Imyanya ndangagitsina iboneka hafi 40% y'abagore na 15% by'abagabo.Abarenga 70% bafite amateka yumuryango.Akenshi, gutwita cyangwa izindi ngaruka ziterwa na hormone.Nubwo ikibazo cyo kwisiga cyane cyane, kimwe cya kabiri cyibi bikoresho bishobora guhinduka ibimenyetso.Umuyoboro w'amaraso ni sisitemu igoye y'amato menshi ya kalibiri n'ubujyakuzimu.Imiyoboro y'amazi yo mumaguru igizwe n'imiyoboro ibiri y'ibanze, imitsi yimbitse y'imitsi hamwe na plexus yo hejuru.Imiyoboro yombi ihujwe nubwato bwimbitse.Imitsi mito mito, iba muri dermis yo hejuru ya papillary, itembera mumitsi yimbitse.Imitsi minini ya reticular iba muri dermis reticular hamwe namavuta yo munsi.Imitsi itagaragara irashobora kuba nini nka mm 1 kugeza kuri 2.Imitsi ihindagurika irashobora kuba mm 4 kugeza kuri 6 z'ubunini.Imitsi minini ifite urukuta runini, ifite ubwinshi bwamaraso ya dexygene, kandi irashobora kuba hejuru ya mm 4 zubujyakuzimu.Guhindagurika mubunini bwubwato, ubujyakuzimu, na ogisijeni bigira ingaruka muburyo bwo kuvura amaguru.Ibikoresho byoroheje bigaragarira hejuru ya oxyhemoglobine yo kwinjirira birashobora kwemerwa kuvura telangiectasias itagaragara cyane kumaguru.Uburebure-burebure, hafi-IR laseri ituma byinjira cyane mubice kandi birashobora no gukoreshwa muguhitamo imitsi yimbitse.Uburebure burebure nabwo burashyuha cyane kurenza uburebure bugufi bwumurambararo hamwe na coefficient nyinshi yo kwinjiza.

Indwara yo kuvura amaguru ya Laser ni ingingo zihita zibura cyangwa kugaragara kugaragara kwa trombose cyangwa guturika.Microthrombi irashobora gushimirwa mumitsi.Mu buryo nk'ubwo, gukuramo amaraso mu maraso bishobora kugaragara biturutse ku guturika kw'imitsi.Rimwe na rimwe, pop yumvikana irashobora gushimirwa no guturika.Iyo igihe gito cyane cyigihe, munsi ya milisegonda 20, zikoreshwa, purpura nini ishobora kugaragara.Ibi birashoboka ko ari ibya kabiri kugeza ubushyuhe bwihuse bwa microcasculaire no guturika.

Nd: Ihinduka rya YAG hamwe nubunini buhindagurika (1-6 mm) hamwe na flux nyinshi zituma imitsi yimitsi ivaho hamwe no kwangirika kwingirangingo.Isuzuma rya Clinical ryerekanye ko impiswi zimara hagati ya milisegonda 40 na 60 zitanga uburyo bwiza bwo kuvura imitsi.

Ingaruka zikunze kugaragara zo kuvura lazeri yo kuvura imitsi ni post hyper hyper pigmentation.Ibi bigaragara cyane hamwe nubwoko bwuruhu rwijimye, izuba, izuba rito (<20 milisegonda), imiyoboro yamenetse, hamwe nimiyoboro ifite trombus.Irashira igihe, ariko ibi birashobora kuba umwaka cyangwa birenga mubihe bimwe.Niba ubushyuhe bukabije butangwa no kuvuga neza cyangwa kumara igihe, ibisebe hamwe ninkovu byakurikiyeho.
