Yintoni iDoppler ultrasound?

I-Doppler ultrasound luvavanyo lokucinga olusebenzisa amaza esandi ukubonisa ukuhamba kwegazi kwimithambo yegazi. I-ultrasound yesiqhelo ikwasebenzisa amaza esandi ukwenza imifanekiso yezakhiwo ngaphakathi emzimbeni, kodwa ayinakubonisa ukuhamba kwegazi.

I-Doppler ultrasound isebenza ngokulinganisa amaza esandi avela kwizinto ezihambayo, ezinje ngeeseli ezibomvu zegazi. Oku kwaziwa njengempembelelo yeDoppler.

Kukho iintlobo ezahlukeneyo zovavanyo lweDoppler ultrasound. Ziquka:

• Umbala weDoppler. Olu hlobo lweDoppler lusebenzisa ikhompyuter ukutshintsha amaza esandi abe yimibala eyahlukeneyo. Le mibala ibonisa isantya kunye nolwalathiso lokuhamba kwegazi ngexesha lokwenyani.
• Doppler yamandla, Uhlobo olutsha lombala weDoppler. Inokubonelela ngenkcukacha engaphezulu yokuhamba kwegazi kunombala oqhelekileyo weDoppler. Kodwa ayinakubonisa icala lokuhamba kwegazi, elinokubaluleka kwezinye iimeko.
• Doppler ebonakalayo. Olu vavanyo lubonisa ulwazi lokuhamba kwegazi kwigrafu, endaweni yemifanekiso enemibala. Inokukunceda ukubonisa ukuba ungakanani umthambo wegazi othintelweyo.
• Duplex Doppler. Olu vavanyo lusebenzisa i-ultrasound esemgangathweni ukuthatha imifanekiso yemithambo yegazi kunye namalungu. Emva koko ikhompyuter ijika imifanekiso ibe yigrafu, njengakwiDoppler ebonakalayo.
• Amaza aqhubekayo iDoppler. Kolu vavanyo, amaza esandi athunyelwa kwaye afunyenwe ngokuqhubekekayo. Ivumela umlinganiso ochanekileyo wegazi ohamba ngesantya esikhawulezayo.

Amanye amagama: Doppler ultrasonography

Isetyenziselwa ntoni?

Uvavanyo lwe-Doppler ultrasound lusetyenziselwa ukunceda ababoneleli ngezempilo ukuba bafumane imeko onayo yokunciphisa okanye ukuvimba ukuphuma kwegazi. Ingasetyenziselwa ukunceda ukufumanisa izifo ezithile zentliziyo. Uvavanyo luhlala lusetyenziselwa:

• Jonga ukusebenza kwentliziyo. Ihlala isenziwa kunye ne-electrocardiogram, uvavanyo olulinganisa imiqondiso yombane entliziyweni.
• Khangela iibhlokhi ekuhambeni kwegazi. Ukuhamba kwegazi okuthintelwe emilenzeni kunokubangela imeko ebizwa ngokuba yi-vein thrombosis (DVT).
• Jonga ukonakala komthambo wegazi kunye neziphene ekubunjweni kwentliziyo.
• Khangela ukunciphisa imithambo yegazi. Imithambo emxinwa engalweni nasemilenzeni kunokuthetha ukuba unemeko ekuthiwa sisifo sephepha lomzimba (PAD). Ukunciphisa imithambo entanyeni kunokuthetha ukuba unemeko ebizwa ngokuba yicarotid artery stenosis.
• Ukujonga ukuhamba kwegazi emva kotyando.
• Jonga ukuhamba kwegazi kwesiqhelo kumfazi okhulelweyo kunye nosana lwakhe olungekazalwa.

Kutheni ndifuna iDoppler ultrasound?

Unokufuna i-Doppler ultrasound ukuba uneempawu zokuncipha kwegazi okanye isifo sentliziyo. Iimpawu ziyahluka ngokuxhomekeke kwimeko ebangela ingxaki. Ezinye zeemeko zokuhamba kwegazi kunye neempawu zingezantsi.

Iimpawu zesifo se-peripheral arterial disease (PAD) zibandakanya:

• Ubudenge okanye ubuthathaka emilenzeni yakho
• Ukuqaqanjelwa yintlungu esinqeni sakho okanye kwimisipha yomlenze xa uhamba okanye unyuka izitepsi
• Imvakalelo ebandayo emlenzeni wakho osezantsi okanye elunyaweni
• Guqula umbala kunye / okanye ulusu olukhazimlayo emlenzeni wakho

Iimpawu zeengxaki zentliziyo zibandakanya:

• Ukuqhawukelwa ngumphefumlo
• Ukudumba kwimilenze yakho, iinyawo, kunye / okanye isisu
• Ukudinwa

Unokufuna kwakhona iDoppler ultrasound ukuba:

• Ukhe wanestroke. Emva kokubetha, umboneleli wakho wezempilo unokuyalela uhlobo oluthile lovavanyo lweDoppler, olubizwa ngokuba yi-transcranial Doppler, ukujonga ukuhamba kwegazi ukuya kwingqondo.
• Ngaba wenzakele kwimithambo yegazi.
• Banyangwa isifo sokuhamba kwegazi.
• Ngaba ukhulelwe kwaye umboneleli wakho ucinga ukuba wena okanye umntwana wakho ongekazalwa unokuba nengxaki yokuhamba kwegazi. Umboneleli wakho unokukrokrela ingxaki ukuba umntwana wakho ongekazalwa mncinci kunokuba kufanelekile kweli nqanaba lokukhulelwa okanye ukuba uneengxaki ezithile zempilo. Oku kubandakanya isifo se-sickle cell okanye i-preeclampsia, uhlobo loxinzelelo lwegazi oluphezulu oluchaphazela abasetyhini abakhulelweyo.

Yintoni eyenzekayo ngexesha le-Doppler ultrasound?

I-Doppler ultrasound ihlala ibandakanya la manyathelo alandelayo:

• Uya kulala itafile, ubonakalise indawo yomzimba wakho evavanyiweyo.
• Umboneleli wezempilo uya kusasaza ijeli ekhethekileyo kulusu kuloo ndawo.
• Umboneleli uya kushenxisa isixhobo esinjenge-wand, esibizwa ngokuba yi-transducer, ngaphaya kwendawo.
• Esi sixhobo sithumela amaza esandi emzimbeni wakho.
• Ukuhamba kweeseli zegazi kubangela utshintsho kwisandi samaza esandi. Unokuva ukutyibilika okanye ukubetha okufana nezandi ngexesha lenkqubo.
• Amaza arekhodwa aguqulwa aba yimifanekiso okanye iigrafu kwisibek 'esweni.
• Emva kokuba uvavanyo luphelile, umboneleli uya kusula i-gel emzimbeni wakho.
• Uvavanyo luthatha malunga nemizuzu engama-30-60 ukulugqiba.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Ukulungiselela iDoppler ultrasound, unokufuna:

• Susa iimpahla kunye nezacholo kwindawo yomzimba kuvavanywa.
• Thintela iisigarethi kunye nezinye iimveliso ezine-nicotine ukuya kuthi ga kwiiyure ezimbini ngaphambi kovavanyo lwakho. I-Nicotine ibangela ukuba imithambo yegazi icuthe, enokuchaphazela iziphumo zakho.
• Kwiindidi ezithile zovavanyo lweDoppler, unokucelwa ukuba ukhawuleze (ungatyi okanye usele) iiyure ezininzi ngaphambi kovavanyo.

Umboneleli wakho wezempilo uya kukwazisa ukuba ngaba ufuna ukwenza nantoni na ukulungiselela uvavanyo lwakho.

Ngaba bukhona ubungozi kuvavanyo?

Akukho bungozi baziwayo kwi-Doppler ultrasound. Kwakhona kuthathwa njengokukhuselekileyo ngexesha lokukhulelwa.

Zithetha ntoni iziphumo?

Ukuba iziphumo zakho bezingaqhelekanga, oko kunokuthetha ukuba une:

• Ukuvaleka okanye ukubamba umthambo
• Imithambo yegazi emxinwa
• Ukuhamba kwegazi ngokungaqhelekanga
• I-aneurysm, ibhaluni-efana nebulge kwimithambo. Yenza ukuba imithambo yolule kwaye ibhitye. Ukuba udonga lucekeceke kakhulu, umthambo unokugqabhuka, ubangele ukopha okusongela ubomi.

Iziphumo zisenokubonisa ukuba kukho ukuhamba kwegazi ngokungaqhelekanga kusana olungekazalwa.

Intsingiselo yeziphumo zakho iya kuxhomekeka ekubeni yeyiphi na indawo evavanywayo. Ukuba unemibuzo malunga neziphumo zakho, thetha nomboneleli wakho wezempilo.
