Kuyadingeka nini ukudlulisa i-ultrasound yemilenze?
I-Ultrasound yamagciwane emilenze engezansi isiza ukuhlonza izifo ezifana ne- thrombosis ne-varicose veins. Ucwaningo lubuye lwenqunywe uma kudingekile ukuba kuhlelwe ngendlela efanele ukwelashwa kokuqeda ukuqina kwe-atherosclerosis noma i-endarteritis.
Izinkomba ze-ultrasound ye-arteries emaphethelweni aphansi yi:
- i-edema ;
- ukukhathala okusheshayo nokuhamba okufishane;
- ubuhlungu obukhulu, ukugubha kanye nosizi;
- i-varicose asterisks ebonakala ngaphansi kwesikhumba;
- izilonda esikhumbeni.
Kunconywa ukuba kwenziwe kulabo abaphethwe yisifo sikashukela futhi babe nesisindo esiningi ngokweqile.
I-ultrasound yemilenze kanjani?
I-Ultrasound ye-veins nemithambo yezinhlangothi ezingezansi ayidingi ukulungiselela kwangaphambili. Ngaphambi kwenqubo, asikho isidingo sokukhansela amalungiselelo asetshenziselwa ukuphatha izitsha zemilenze. Uma isiguli sigqoke izingubo zangaphansi zokucindezela, kuzodingeka zisuswe, ngoba idivayisi kufanele ifinyelele isikhumba.
Ngaphambi kokuqala i-ultrasound emaphethelweni aphansi, i-gel ekhethekile isetshenziswa. Okokuqala, ukuhlolwa kwemizwa nemithambo yegazi kuqhutshwa endaweni ephakeme, imilenze yomabili iguqa ngamadolo. Emva kwalokhu, udokotela uyazihlola uma isiguli sisesikhundleni esiqondile. Imikhawulo ye-radiation ye-ultrasound ye-arteries yezinyathelo ezingezansi ikhethwe ngesandla, ngoba incike ekujuleni kwendawo yemikhumbi, kanye nezinga elidingekile lokubeka imininingwane yazo. Ezimweni eziningi, imvamisa ivela ku-6 kuya ku-12 MHz. Izindebe ezijulile zingcono ukuhlola ama-sensor low-frequency sensors.
