I-Carotid duplex

ICarotid duplex ukuhlolwa kwe-ultrasound okukhombisa ukuthi igazi ligeleza kahle kangakanani ngemithambo ye-carotid. Imithambo ye-carotid itholakala entanyeni. Banikeza igazi ngqo ebuchosheni.

I-Ultrasound yindlela engenabuhlungu esebenzisa amagagasi omsindo ukudala izithombe ezingaphakathi komzimba. Isivivinyo senziwa kwelebhu yemithambo yegazi noma emnyangweni we-radiology.

Ukuhlolwa kwenziwa ngale ndlela elandelayo:

• Ulele ngomhlane. Ikhanda lakho lisekelwa ukuligcina linganyakazi. Isazi se-ultrasound sisebenzisa i-gel esekwe emanzini entanyeni yakho ukusiza ngokudluliswa kwamagagasi omsindo.
• Ngokulandelayo, uchwepheshe uhambisa induku ebizwa ngokuthi i-transducer emuva naphambili phezu kwendawo.
• Umshini uthumela amaza omsindo emithanjeni esentanyeni yakho. Amagagasi omsindo agxuma emithanjeni yegazi futhi akhe izithombe noma izithombe ezingaphakathi kwemithambo yegazi.

Akukho ukulungiselela okudingekayo.

Ungase uzwe ingcindezi ethile njengoba i-transducer inyakaziswa entanyeni yakho. Ingcindezi akufanele idale noma yibuphi ubuhlungu. Ungase futhi uzwe umsindo othi "whooshing". Lokhu kujwayelekile.

Lokhu kuhlolwa kubheka ukuhamba kwegazi emithanjeni ye-carotid. Ingathola:

• Ukujiya kwegazi (thrombosis)
• Ukunciphisa emithanjeni (stenosis)
• Ezinye izimbangela zokuvalwa emithanjeni ye-carotid

Udokotela wakho angayalela lokhu kuhlolwa uma:

• Ube nesifo sohlangothi noma ukuhlaselwa yischemic okwedlulayo (TIA)
• Udinga ukuhlolwa kokulandelela ngoba umthambo wakho we-carotid utholakale unciphile esikhathini esedlule noma uke wahlinzwa emthanjeni
• Udokotela wakho uzwa umsindo ongajwayelekile obizwa nge-bruit phezu kwemithambo yentamo ye-carotid. Lokhu kungasho ukuthi umthambo uyancipha.

Imiphumela izotshela udokotela wakho ukuthi imithambo yakho ye-carotid ivuleke noma inciphe kangakanani. Isibonelo, imithambo yegazi ingancishiswa ngo-10%, i-50% inciphe, noma i-75% inciphe.

Umphumela ojwayelekile usho ukuthi ayikho inkinga ngokugeleza kwegazi emithanjeni ye-carotid. Umthambo awunakho ukuvinjelwa okuphawulekayo, ukuncipha, noma enye inkinga.

Umphumela ongajwayelekile usho ukuthi umthambo ungancishiswa, noma okuthile kushintsha ukugeleza kwegazi emithanjeni ye-carotid. Lesi yisibonakaliso se-atherosclerosis noma ezinye izimo zemithambo yegazi.

Ngokuvamile, lapho umthambo uncipha kakhulu, inkulu ingozi yokushaywa unhlangothi.

Ngokuya ngemiphumela, udokotela wakho angafuna ukuthi:

• Cabanga ngokuhlinzwa
• Yiba nokuhlolwa okwengeziwe (okufana ne-cerebral angiography, i-CT angiography, kanye ne-magnetic resonance angiography)
• Landela ukudla okunempilo nendlela yokuphila ukuvimbela ukuqina kwemithambo yegazi
• Phinda isivivinyo futhi ngokuzayo

Azikho izingozi ngokuba nale nqubo.
