Laser ya 1064 Nd:YAG ikoresha amashanyarazi maremare yagaragaye ko ari uburyo bwiza bwo kuvura hemangioma n’indwara z’imitsi ku barwayi b’uruhu rwijimye, ikaba ari n’inyungu nini zo kuba uburyo bwizewe, bwihanganirwa kandi buhendutse, bufite igihe gito cyo kuruhuka no kugira ingaruka nke ku buzima.
Uburyo bwo kuvura imitsi yo mu kaguru n’iy’amaguru yimbitse hakoreshejwe laser ndetse n’izindi ndwara zitandukanye z’imitsi bikomeje kuba bumwe mu buryo bukunze gukoreshwa na laser mu buvuzi bw’uruhu no mu buvuzi bw’uruhu. Mu by’ukuri, laser yahindutse uburyo bwo kuvura indwara z’imitsi nka hemangioma na port-wine stains ndetse no kuvura indwara ya rosacea. Ubwoko bw’indwara z’imitsi zivukanwa n’iziboneka mu buryo bufatika hakoreshejwe laser bukomeje kwiyongera kandi busobanurwa n’ihame rya selective photothermolysis. Ku bijyanye na systeme ya laser yihariye mu mitsi, intego igamije ni oxyhemoglobin mu mitsi.
Mu kwibanda kuri oxyhemoglobini, ingufu zijyanwa ku rukuta rw'imitsi ikikije. Kuri ubu, laser ya 1064-nm Nd: YAG hamwe n'ibikoresho bya vis/near infrared (IR) ikaze cyane (IPL) byombi bitanga umusaruro mwiza. Itandukaniro rikomeye ariko, ni uko laser ya Nd: YAG ishobora kwinjira cyane, bityo ikaba ikwiriye cyane mu kuvura imitsi minini kandi yimbitse nk'imitsi y'amaguru. Ikindi cyiza cya laser ya Nd: YAG ni uko ifite ubushobozi bwo kwinjiza melanin mu buryo buke. Hamwe n'ubushobozi bwo kwinjiza melanin mu buryo buke, nta mpungenge nyinshi ku kwangirika kwa epidermal bityo ishobora gukoreshwa neza mu kuvura abarwayi bafite ibara ryijimye. Ingaruka zo kwangirika cyane nyuma yo kubyimba zishobora kugabanuka cyane hakoreshejwe ibikoresho bikonjesha epidermal. Gukonjesha epidermal ni ngombwa kugira ngo birinde kwangirika kwa epidermal mu buryo budasubirwaho.
Ubuvuzi bw'imitsi y'amaguru ni bumwe mu buryo bukunze gusabwa bwo kwisiga. Imitsi ishyushye iboneka hafi 40% by'abagore na 15% by'abagabo. Abarenga 70% bafite amateka yo mu muryango. Akenshi, gutwita cyangwa izindi misemburo biragaragara. Nubwo ikibazo cy'ubwiza ahanini ari ikibazo cy'ubwiza, imitsi irenga kimwe cya kabiri cy'iyi mitsi ishobora kugaragaza ibimenyetso. Urusobe rw'imitsi ni uburyo bugoye bw'imitsi myinshi ifite ubushobozi n'ubujyakuzimu butandukanye. Imitsi isohoka mu mitsi igizwe n'imiyoboro ibiri y'ibanze, plexus y'imitsi miremire n'plexus y'uruhu rwo hejuru. Imiyoboro ibiri ihuzwa n'imitsi itoboye cyane. Imitsi mito y'uruhu, iba mu dermis yo hejuru ya papillary, imanuka ikagera mu mitsi yimbitse y'uruhu. Imitsi minini y'uruhu iba mu dermis yimbitse y'uruhu no mu binure byo munsi y'umubiri. Imitsi yo hejuru ishobora kuba minini nka mm 1 kugeza kuri 2. Imitsi yimbitse ishobora kuba ifite ingano ya mm 4 kugeza kuri 6. Imitsi minini ifite inkuta nini, ifite amaraso menshi adahumeka, kandi ishobora kuba irenga mm 4 z'ubujyakuzimu. Ihindagurika ry'ingano y'imitsi, uburebure bw'ubujyakuzimu, n'umwuka uhumeka bigira ingaruka ku buryo imitsi y'amaguru ivurwa n'imikorere yayo. Ibikoresho by'urumuri bigaragara byibanda ku gice cyo hejuru cy'umuvuduko wa oksijemoglobini bishobora kuba byemewe mu kuvura telangiectasias zo hejuru cyane ku maguru. Laser ndende, hafi ya IR yemerera kwinjira cyane mu ngingo ndetse ishobora no gukoreshwa mu kwibasira imitsi yo mu nda iri hagati y'amatwi. Imivuduko miremire y'umuvuduko kandi ishyuha kimwe kurusha imivuduko migufi ifite ubushobozi bwo kwibasira amaguru.
Imitsi yo ku maguru ya laser ni ukubura kw'imitsi ako kanya cyangwa kugaragara kw'imitsi cyangwa gucika kw'amaraso. Imitsi mito ishobora kugaragara mu ruhu rw'imitsi. Mu buryo nk'ubwo, amaraso ashobora kugaragara mu mitsi yo ku maguru bitewe no gucika kw'imitsi. Rimwe na rimwe, ijwi ryumvikana rishobora kugaragara iyo imitsi yo ku maguru itangiye gucika. Iyo hakoreshejwe igihe gito cyane, munsi ya milisegonda 20, hashobora kubaho purpura nini. Ibi bishobora kuba biterwa no gushyuha no gucika kw'imitsi mito vuba.
Impinduka za Nd: YAG zifite ingano zitandukanye z'utudomo (mm 1-6) n'imiterere yo hejuru yemerera gukuraho imitsi y'amaraso hamwe n'ibyangiritse bike by'uturemangingo. Isuzuma rya muganga ryagaragaje ko igihe cy'amapilo kiri hagati ya milisegonda 40 na 60 gitanga uburyo bwiza bwo kuvura imitsi y'amaguru.
Ingaruka mbi zikunze kugaragara cyane zo kuvura imitsi y'amaguru hakoreshejwe laser ni ibara ryiyongera nyuma yo kubyimba. Ibi bikunze kugaragara cyane ku ruhu rwijimye, ku zuba, igihe gito cy'amagufwa (
