I-duplex ultrasound

I-duplex ultrasound luvavanyo lokujonga ukuba igazi lihamba njani kwimithambo yakho kunye nemithambo.

I-duplex ultrasound idibanisa:

• I-ultrasound yesiko: Oku kusebenzisa amaza esandi aphuma kwimithambo yegazi ukwenza imifanekiso.
• I-Doppler ultrasound: Oku kurekhoda amaza esandi ebonisa izinto ezihambayo, ezinje ngegazi, ukulinganisa isantya kunye neminye imiba yendlela ezihamba ngayo.

Kukho iintlobo ezahlukeneyo zoviwo lwe-duplex ultrasound. Ezinye zibandakanya:

• I-arterial kunye ne-venous duplex ultrasound yesisu. Olu vavanyo luvavanya imithambo yegazi kunye nokuhamba kwegazi kwindawo esiswini.
• I-Carotid duplex ultrasound ijonge i-carotid artery entanyeni.
• I-duplex ultrasound yeziphelo ijonge ezingalweni okanye emilenzeni.
• I-renal duplex ultrasound ivavanya izintso kunye nemithambo yegazi.

Kusenokufuneka unxibe isinxibo sonyango. Uya kulala phantsi etafileni, kwaye uchwepheshe we-ultrasound uya kusasaza i-gel kwindawo evavanyiweyo. Ijeli inceda amaza esandi angene kwizicubu zakho.

I-wand, ebizwa ngokuba yi-transducer, ishukunyiswa kwindawo evivinywayo. Eli tyeli lithumela amaza esandi. Ikhompyuter ilinganisa indlela amaza esandi abuya umva ngayo, kwaye itshintsha amaza esandi abe yimifanekiso. I-Doppler yenza isandi "sokushukuma", sisandi segazi lakho elihamba kwimithambo kunye nemithambo.

Kuya kufuneka uhlale uzolile ngexesha loviwo. Unokucelwa ukuba ulale kwiindawo ezahlukileyo zomzimba, okanye uthathe umoya ophefumlayo kwaye ubambe.

Ngamanye amaxesha ngexesha le-duplex ultrasound yemilenze, umboneleli wezempilo unokubala i-ankle-brachial index (ABI). Kuya kufuneka unxibe iikhofu zoxinzelelo lwegazi ezingalweni nasemilenzeni yakho kolu vavanyo.

Inombolo ye-ABI ifunyanwa ngokwahlula uxinzelelo lwegazi emaqatheni ngoxinzelelo lwegazi engalweni. Ixabiso le-0.9 okanye ngaphezulu liqhelekile.

Ngokwesiqhelo, akukho lungiselelo lolu vavanyo.

Ukuba une-ultrasound yendawo yesisu sakho, unokucelwa ukuba ungatyi okanye usele emva kobusuku. Xelela umntu owenza uvavanyo lwe-ultrasound ukuba uthatha nawaphi na amayeza, anje ngegazi. Oku kunokuchaphazela iziphumo zovavanyo.

Unokuziva uxinzelelo xa i-wand ishukunyiswa emzimbeni, kodwa akukho nto iphazamisayo ixesha elininzi.

I-duplex ultrasound ingabonisa ukuba igazi lihamba njani ukuya kwiindawo ezininzi zomzimba. Inokwazisa ububanzi besitya segazi kwaye ityhile naziphi na izithintelo. Olu vavanyo lukhetho olungenakuncitshiswa kancinci kune-arteriography kunye ne-venography.

I-duplex ultrasound inokunceda ukufumanisa imeko elandelayo:

• I-aneurysm yesisu
• Ukuvalelwa komzimba
• Ihlwili legazi
• Isifo esiqhelekileyo seCarotid (Jonga: ICarotid duplex)
• Isifo se-vascular renal
• Iimvumba ze-Varicose
• Ukungoneli kwe-venous

I-renal duplex ultrasound inokusetyenziswa emva kotyando lotyando. Oku kubonisa ukuba zisebenza kakuhle kangakanani izintso.

Iziphumo eziqhelekileyo kukuhamba kwegazi okuqhelekileyo ngemithambo kunye nemithambo. Kukho uxinzelelo lwegazi oluqhelekileyo kwaye akukho phawu lokunciphisa okanye ukuvalwa komthambo wegazi.

Iziphumo ezingaqhelekanga zixhomekeke kwindawo ethile evavanyiweyo. Isiphumo esingaqhelekanga sinokubakho ngenxa yegazi okanye ukwanda kweplate kwisitya segazi.

Akukho bungozi.

Ukutshaya kunokutshintsha iziphumo ze-ultrasound yeengalo nemilenze. Oku kwenzeka ngenxa yokuba inicotine inokubangela ukuncipha kwemithambo yegazi.
