I-Ultranscial Doppler ultrasound

I-Transcranial doppler ultrasound (TCD) luvavanyo lokuqonda isifo. Ilinganisa ukuhamba kwegazi kuye ngaphakathi nangaphakathi kwengqondo.

I-TCD isebenzisa amaza esandi ukwenza imifanekiso yokuhamba kwegazi ngaphakathi kwengqondo.

Nantsi indlela olwenziwa ngayo uvavanyo:

• Uya kulala ngomqolo kwitafile ebotshelelwe ngentloko kunye nentamo emqamelweni. Intamo yakho yolulwe kancinci. Okanye ungahlala esitulweni.
• Ingcali ichitha i-gel esekwe emanzini kwiitempile zakho kunye neenkophe, phantsi komhlathi wakho, naphantsi kwentamo yakho. Ijeli inceda amaza esandi angene kwizicubu zakho.
• I-wand, ebizwa ngokuba yi-transducer, ishukunyiswa kwindawo evivinywayo. I-wand yathumela amaza esandi. Amaza esandi ahamba emzimbeni wakho kwaye aphume kwindawo efundwayo (kule meko, ingqondo yakho kunye nemithambo yegazi).
• Ikhompyuter ijonga ipateni eyenziwe ngamaza esandi xa ibuyela umva. Yenza umfanekiso ovela kumaza esandi. I-Doppler yenza isandi "sokushukuma", sisandi segazi lakho elihamba kwimithambo kunye nemithambo.
• Uvavanyo lunokuthatha imizuzu engama-30 ukuya kwiyure e-1 ukulugqiba.

Akukho lungiselelo lukhethekileyo luyafuneka kolu vavanyo. Awudingi kutshintsha ube yingubo yonyango.

Khumbula uku:

• Susa iilensi zonxibelelwano ngaphambi kovavanyo ukuba uzinxibile.
• Gcina amehlo akho evaliwe xa i-gel isetyenziselwa iinkophe zakho ukuze ungayifumani emehlweni akho.

Ijeli inokuziva ibanda kulusu lwakho. Unokuziva uxinzelelo njengoko i-transducer ishukunyiswa yentloko nasentanyeni. Uxinzelelo akufuneki lubangele nayiphi na intlungu. Unokuva kwakhona isandi esithi "whooshing". Oku kuqhelekile.

Uvavanyo lwenziwe ukufumana iimeko ezichaphazela ukuhamba kwegazi ukuya kwingqondo:

• Ukunciphisa okanye ukuvaleka kwemithambo kwingqondo
• Stroke okanye uhlaselo lwexeshana lwe-ischemic (i-TIA okanye i-ministerroke)
• Ukopha kwisithuba phakathi kwengqondo kunye nezicubu ezigubungela ingqondo (subarachnoid hemorrhage)
• Ukubhaliswa kwesitya segazi kwingqondo (i-cerebral aneurysm)
• Guqula uxinzelelo ngaphakathi kolukakayi (uxinzelelo lwangaphakathi)
• I-Sickle cell anemia, ukuvavanya umngcipheko wokubetha

Ingxelo yesiqhelo ibonisa ukuhamba kwegazi eliqhelekileyo ukuya kwingqondo. Akukho kuncipha okanye ukuvaleka kwimithambo yegazi ekhokelela ngaphakathi nangaphakathi kwengqondo.

Iziphumo ezingaqhelekanga zithetha ukuba umthambo unokuncitshiswa okanye into itshintshe ukuhamba kwegazi kwimithambo yengqondo.

Akukho bungozi ngokuba nale nkqubo.
