I-Endovenous Laser

I-Endovenous laser lunyango olungenabungozi kangako kwimithambo yegazi evalekileyo olungenabungozi kangako kunokukhupha imithambo yesaphenous yendabuko kwaye lunika izigulane inkangeleko enqwenelekayo ngenxa yokuba zingenabungozi kangako. Umgaqo wonyango kukusebenzisa amandla elaser ngaphakathi kwimithambo yegazi (i-intravenous lumen) ukutshabalalisa umthambo wegazi osele unengxaki.

Inkqubo yonyango lwe-endovenous laser ingenziwa ekliniki, isigulana sivukile ngokupheleleyo ngexesha lenkqubo, kwaye ugqirha uza kujonga imeko yemithambo yegazi ngezixhobo ze-ultrasound.

Ugqirha uqala ngokufaka i-anesthetic yasekuhlaleni ethangeni lomguli aze enze umngxuma ethangeni omkhulu kancinci kunomngxuma we-pinhole. Emva koko, kufakwa i-fiber optic catheter esuka enxebeni iye emthanjeni. Njengoko ihamba ngomthambo onesifo, i-fiber ikhupha amandla e-laser ukuze itshise udonga lomthambo. Iyancipha, kwaye ekugqibeleni wonke umthambo uyasuswa, nto leyo esombulula ngokupheleleyo ingxaki yemithambo evalekileyo.

Emva kokuba unyango lugqityiwe, ugqirha uza kulibopha kakuhle inxeba, aze umguli akwazi ukuhamba njengesiqhelo aze aqhubeke nobomi bakhe obuqhelekileyo nemisebenzi yakhe.

Emva konyango, isigulana sinokuhamba emhlabeni emva kokuphumla okufutshane, kwaye ubomi baso bemihla ngemihla abuchaphazeleki, kwaye sinokuqhubeka nemidlalo emva kweeveki ezimbini.

1. I-laser ye-980nm efunxa ngokulinganayo emanzini nasegazini, inika isixhobo sotyando esomeleleyo esisebenza kuzo zonke iinjongo, kwaye kwi-30/60Watts yokukhupha, ngumthombo wamandla aphezulu okusebenza kwe-endovascular.

2. IIlaser eyi-1470nmngokufunxwa okuphezulu kakhulu emanzini, kubonelela ngesixhobo esichanekileyo kakhulu sokunciphisa umonakalo wobushushu obujikeleze izakhiwo zemithambo yegazi. Ngoko ke, kuyacetyiswa kakhulu kumsebenzi we-endovascular.

Ubuncinane, ubude be-laser obuyi-1470 bungcono ngokuphindwe kangama-40 xa bufunxwa ngamanzi kunye ne-oxyhemoglobin kune-laser eyi-980nm, nto leyo evumela ukutshatyalaliswa komthambo ngokukhetha, ngamandla amancinci kwaye kunciphisa iziphumo ebezingalindelekanga.

Njenge-laser ehambelana namanzi, i-laser ye-TR1470nm ijolise emanzini njenge-chromophore ukuze ifunxe amandla e-laser. Ekubeni isakhiwo semithambo ikakhulu ngamanzi, kuthiwa ubude be-laser obuyi-1470 nm bufudumeza iiseli ze-endothelial ngokufanelekileyo ngomngcipheko omncinci womonakalo we-collateral, nto leyo ekhokelela ekukhutshweni kwemithambo ngokufanelekileyo.

Sikwabonelela ngeefayibha zeradial.
I-radial fiber ekhupha kwi-360° inika i-endovenous thermal ablation efanelekileyo. Ngoko ke kunokwenzeka ukufaka amandla e-laser ngobunono nangokulinganayo kwi-lumen yomthambo kwaye uqinisekise ukuvalwa komthambo ngokusekelwe ekutshatyalalisweni kwe-photothermal (kumaqondo obushushu aphakathi kwe-100 ne-120°C).IFAYIBHA YERADIAL YE-TRANGELixhotyiswe ngeempawu zokhuseleko zokulawula ngokugqibeleleyo inkqubo yokutsala.
