I-Transcranial Doppler ultrasound

I-Transcranial doppler ultrasound (TCD) isivivinyo sokuxilonga. Ilinganisa ukugeleza kwegazi kuye nangaphakathi kobuchopho.

I-TCD isebenzisa amaza omsindo ukudala izithombe zokugeleza kwegazi ngaphakathi kobuchopho.

Nakhu ukuthi kwenziwa kanjani ukuhlolwa:

• Uzolala ngomhlane etafuleni eligwedwe ngekhanda nentamo kumcamelo. Intamo yakho yeluliwe kancane. Noma ungahlala esihlalweni.
• Uchwepheshe ugcobisa i-gel esekwe emanzini emathempelini nasezinkophe zakho, ngaphansi komhlathi wakho, naphansi kwentamo yakho. Ijeli isiza amaza omsindo angene ezicutshini zakho.
• I-wand, ebizwa ngokuthi i-transducer, ihanjiswa endaweni evivinywayo. Induku ithumela amaza omsindo. Amagagasi omsindo ahamba emzimbeni wakho bese eshaya endaweni efundwayo (kulokhu, ubuchopho bakho nemithambo yegazi).
• Ikhompyutha ibheka iphethini eyenziwe amagagasi omsindo lapho ibuyela emuva. Kwakha isithombe esivela kumagagasi omsindo. IDoppler yakha umsindo "wokushwibeka", okungumsindo wegazi lakho elihamba ngemithambo nemithambo.
• Ukuhlolwa kungathatha imizuzu engama-30 kuya ehoreni eli-1 ukuqeda.

Akukho ukulungiselela okukhethekile okudingekayo kulolu vivinyo. Awudingi ukushintsha ube ingubo yezokwelapha.

Khumbula uku:

• Susa amalensi wokuxhumana ngaphambi kokuhlolwa uma uwagqoka.
• Gcina amehlo akho evaliwe lapho i-gel isetshenziswa kumajwabu amehlo akho ukuze ungayitholi emehlweni akho.

Ijeli lingazizwa libanda esikhunjeni sakho. Ungazizwa unengcindezi njengoba i-transducer ihanjiswa ekhanda nasentanyeni. Ingcindezi akufanele idale noma yibuphi ubuhlungu. Ungase futhi uzwe umsindo othi "whooshing". Lokhu kujwayelekile.

Ukuhlolwa kwenziwa ukuthola izimo ezithinta ukugeleza kwegazi kuya ebuchosheni:

• Ukunciphisa noma ukuvinjelwa kwemithambo ebuchosheni
• I-Stroke noma i-ischemic attack yesikhashana (i-TIA noma i-ministroke)
• Ukopha esikhaleni esiphakathi kobuchopho nezicubu ezimboza ubuchopho (i-subarachnoid hemorrhage)
• Ukubhaliswa kwesitsha segazi ebuchosheni (i-cerebral aneurysm)
• Shintsha ekucindezelekeni ngaphakathi kogebhezi (ingcindezi yangaphakathi)
• I-Sickle cell anemia, ukuhlola ubungozi besifo sohlangothi

Umbiko ojwayelekile ukhombisa ukugeleza kwegazi okujwayelekile kuya ebuchosheni. Akukho ukuncipha noma ukuvinjelwa emithanjeni yegazi eholela ngaphakathi nangaphakathi kobuchopho.

Umphumela ongajwayelekile usho ukuthi umthambo ungancishiswa noma okuthile kuguqula ukugeleza kwegazi emithanjeni yobuchopho.

Azikho izingozi ngokuba nale nqubo.
