Imithambo ye-Varicose yemilenze engezansi iyizifo ezivamile futhi ezivame ukwenzeka ekuhlinzweni kwemithambo yegazi. Ukusebenza kusenesikhathi kokungakhululeki kwe-acid yemilenze, iqembu elibuhlungu lemithambo emincane, ngokuqhubeka kwesifo, kungavela ukuqubuka kwesikhumba, ukuguquka kwebala, ukususwa kwesikhumba, i-lipid sclerosis ngisho nesilonda. Izindlela zokwelapha imithambo ye-varicose yemilenze engezansi zifaka phakathi ukushintsha indlela yokuphila, ukwelashwa ngemithi, ukwelashwa ngepayipi lokucindezela, ukubopha okuphezulu kanye nokususa imithambo ye-saphenous, i-sclerotherapy njalo njalo. Ukuhlinzwa kwendabuko sekuqhubeke iminyaka engaphezu kwe-100.
Njengamanje, ukuhlinzwa kwemithambo ye-varicose engezansi kwemilenze kuye kwavame ukungabi yingozi kangako, njengokususwa kwe-laser endovenous, ukususwa kwe-radiofrequency, ukwelashwa nge-microwave, njll. Ukufakwa kwemithambo ye-saphenous eyinhloko kanye nokususwa kwayo akusasetshenziswa kakhulu. Ngokuthuthuka kwamasu okungenangozi kangako kanye nokuqongelela ulwazi lodokotela, amasu okungenangozi kangako azozuzisa iziguli eziningi ezinemithambo ye-varicose engezansi futhi athathe indawo yokuhlinzwa kwendabuko.
Iziqondiso ze-American Society for Vascular Surgery kanye ne-American Venous Forum zokwelashwa kwemithambo ye-Varicose ye-Lower Extremity kanye nezifo zemithambo ezingamahlalakhona zifaka phakathi i-endovenous laser ablation (I-ELVA) kanye nokususwa kwe-radiofrequency (RFA) njengezincomo ze-Class IB. Izifundo zikhombisile ukuthiI-laser engu-1470nmI-radial fiber inezinkinga ezimbalwa kanye nokubhoboka uma kuqhathaniswa ne-ablation yendabuko noma ukuhlinzwa okuvamile kwe-laser. Iyindlela ephumelelayo yokwelapha imithambo ye-varicose yezingxenye ezingezansi futhi ingenye yezindlela ezinhle kakhulu zokuhlinzwa ngesikhathi sokubhoboka kwemithambo yegazi yesigaba esisodwa. Uma kuqhathaniswa ne-point laser, i-ring laser output fiber ingenza amandla e-laser asatshalaliswe ngokulinganayo odongeni lwemithambo yegazi engu-360°, amandla asetshenziswayo aphansi, izinga lokubhoboka liyancipha, futhi akukho carbonization odongeni lwemithambo yegazi. Izinga lokumuncwa kwamanzi kanye ne-hemoglobin enobude be-1470nm liphakeme kakhulu kunele-laser evamile, futhi amandla asebenza ngqo odongeni lwemithambo yegazi, olungavala ngokuphelele nangokulinganayo imithambo yegazi. Sekukonke, i-1470nm laser enokwelashwa kwe-radial fiber yemithambo ye-varicose yezingxenye ezingezansi inezinzuzo ezibalulekile:
1) Ukuvalwa okusheshayo kanye nomphumela oqondile wokwelapha;
2) Kungenziwa ukususwa kwesiqu esikhulu kune-radiofrequency;
3) Ingxenye yokusebenza ye-radial fiber ayithinti ngqo udonga lwemithambo yegazi, futhi indawo ye-radial annular inamandla afanayo odongeni lwemithambo yegazi ngaphandle kokubangela i-carbonization.
4) Kungcono kakhulu kunezinye izisetshenziswa zokuvala ukushisa.
Kuyaphawuleka ukuthi i-laser ye-triangle1470nm diode inomklamo olula futhi ohlangene, Uhlelo olusha lokusabalalisa ukushisa kanye nokugcina isiqandisi luthuthukisa kakhulu ukusebenza kahle kokuguqulwa kwamandla kwe-laser futhi lugcina izinga lokushisa lokusebenza lizinzile. Kuhlanganiswe ne-i-radial fiberngokukhanya okukhipha okungu-360°, amandla e-laser asetshenziswa ngqo odongeni lwemithambo yegazi. I-Ecchymosis kanye nobuhlungu kanye neminye imiphumela emibi kuncishisiwe kakhulu, okusiza kakhulu ekuhlinzeni okungangenisi kakhulu.
