I-duplex ultrasound

I-duplex ultrasound isivivinyo sokubona ukuthi igazi lihamba kanjani emithanjeni yakho nasemithanjeni yakho.

I-duplex ultrasound ihlanganisa:

• I-ultrasound yendabuko: Lokhu kusebenzisa amagagasi omsindo agxuma emithanjeni yegazi ukudala izithombe.
• I-Doppler ultrasound: Lokhu kuqopha amagagasi omsindo akhombisa izinto ezihambayo, njengegazi, ukukala isivinini sazo nezinye izici zokuhamba kwazo.

Kunezinhlobo ezahlukahlukene zezivivinyo ze-duplex ultrasound. Ezinye zifaka:

• I-arterial and venous duplex ultrasound yesisu. Lokhu kuhlolwa kubheka imithambo yegazi nokugeleza kwegazi endaweni yesisu.
• I-Carotid duplex ultrasound ibheka umthambo we-carotid entanyeni.
• I-duplex ultrasound yamaphethelo ibheka izingalo noma imilenze.
• I-renal duplex ultrasound ihlola izinso nemithambo yegazi.

Kungase kudingeke ukuthi ugqoke ingubo yezokwelapha. Uzolala phansi etafuleni, bese uchwepheshe we-ultrasound esabalalisa i-gel endaweni evivinywayo. Ijeli isiza amaza omsindo angene ezicutshini zakho.

I-wand, ebizwa ngokuthi i-transducer, ihanjiswa endaweni evivinywayo. Le nduku ithumela amaza omsindo. Ikhompyutha ilinganisa ukuthi amagagasi omsindo abonakala kanjani emuva, futhi iguqule amaza omsindo abe yizithombe. IDoppler yakha umsindo "wokushwibeka", okungumsindo wegazi lakho elihamba ngemithambo nemithambo.

Udinga ukuhlala unganyakazi ngesikhathi sokuhlolwa. Ungacelwa ukuthi ulale ezindaweni ezahlukahlukene zomzimba, noma uthathe umoya ophefumulayo bese uwubamba.

Kwesinye isikhathi ngesikhathi se-duplex ultrasound yemilenze, umhlinzeki wezokunakekelwa kwempilo angabala inkomba ye-ankle-brachial (ABI). Uzodinga ukugqoka izinkinobho zomfutho wegazi ezingalweni nasemilenzeni kulolu vivinyo.

Inombolo ye-ABI itholakala ngokuhlukanisa umfutho wegazi emaqakaleni ngumfutho wegazi engalweni. Inani elingu-0.9 noma ngaphezulu livamile.

Imvamisa, akukho ukulungiselela kwalolu vivinyo.

Uma une-ultrasound yendawo yesisu sakho, ungacelwa ukuthi ungadli noma uphuze ngemuva kwamabili. Tshela umuntu owenza ukuhlolwa kwe-ultrasound uma uthatha noma yimiphi imithi, efana nezinciphisi zegazi. Lokhu kungathinta imiphumela yokuhlolwa.

Ungazizwa unengcindezi ethile njengoba induku ihanjiswa emzimbeni, kepha akukho ukungakhululeki isikhathi esiningi.

I-duplex ultrasound ingakhombisa ukuthi igazi ligeleza kanjani liye ezingxenyeni eziningi zomzimba. Ingatshela nobubanzi besitsha segazi futhi iveze noma yikuphi ukuvinjelwa. Lokhu kuhlolwa kuyindlela engatheni yokuhlasela kune-arteriography ne-venography.

I-duplex ultrasound ingasiza ukuxilonga lezi zimo ezilandelayo:

• I-aneurysm yesisu
• Ukuvalwa komzimba
• Ihluli
• Isifo seCarotid (Bheka: I-Carotid duplex)
• Isifo semithambo yezinso
• Imithambo ye-Varicose
• Ukungasebenzi kahle kwe-venous

I-renal duplex ultrasound nayo ingasetshenziswa ngemuva kokuhlinzwa kokufakelwa. Lokhu kukhombisa ukuthi izinso ezintsha zisebenza kahle kanjani.

Umphumela ojwayelekile ukugeleza kwegazi okujwayelekile emithanjeni nasemithanjeni yegazi. Kukhona umfutho wegazi ojwayelekile futhi akukho phawu lokuncipha noma ukuvimba kwesitsha segazi.

Umphumela ongajwayelekile uncike endaweni ethize ehlolwayo. Umphumela ongajwayelekile ungaba ngenxa yegazi noma i-plaque buildup esitsheni segazi.

Azikho izingozi.

Ukubhema kungashintsha imiphumela ye-ultrasound yezingalo nemilenze. Lokhu kwenzeka ngoba i-nicotine ingadala ukuthi imithambo yegazi inciphise (ukuncipha).

• Ukubekwa kwe-angioplasty nokuma okuqinile - imithambo yegazi - ukukhipha
• I-vein thrombosis ejulile - ukukhipha

• Ukuhlolwa kwe-ultrasound / doppler ultrasound
