Ukuhlolwa kwe-Doppler ultrasound kwengalo noma umlenze

Lokhu kuhlolwa kusebenzisa i-ultrasound ukubheka ukuhamba kwegazi emithanjeni emikhulu nasemithanjeni yezingalo noma yemilenze.

Ukuhlolwa kwenziwa emnyangweni we-ultrasound noma we-radiology, igumbi lesibhedlela, noma ebhodini lemithambo eseceleni.

Ngesikhathi sokuhlolwa:

• Ijeli encibilikiswa ngamanzi ibekwa entweni ephathwa ngesandla ebizwa ngokuthi i-transducer. Le divayisi iqondisa amaza omsindo aphakeme kakhulu emthanjeni noma emithanjeni evivinywayo.
• Izindwangu zomfutho wegazi zingafakwa ezingxenyeni ezihlukene zomzimba, kufaka phakathi ithanga, inkonyane, iqakala, namaphuzu ahlukene asengalweni.

Uzodinga ukususa izingubo engalweni noma emlenzeni ohlolwayo.

Kwesinye isikhathi, umuntu owenza isivivinyo kuzodingeka ukuthi acindezele emthanjeni ukuze aqiniseke ukuthi ayinayo i-clot. Abanye abantu bangase bezwe ubuhlungu obuncane ngenxa yengcindezi.

Lokhu kuhlolwa kwenziwa njengesinyathelo sokuqala sokubheka imithambo yegazi nemithambo. Kwesinye isikhathi, i-arteriography kanye ne-venography kungadingeka kamuva. Ukuhlolwa kwenziwa ukusiza ukuxilonga:

• I-arteriosclerosis yezingalo noma yemilenze
• Ukuqina kwegazi (i-vein thrombosis ejulile)
• Ukungasebenzi kahle kwe-venous

Isivivinyo singasetshenziswa futhi uku:

• Bheka ukulimala emithanjeni
• Qapha ukwakhiwa kabusha kwemithambo yegazi futhi udlule ubungcweti

Umphumela ojwayelekile usho ukuthi imithambo yegazi ayibonisi zimpawu zokuncipha, amahlule, noma ukuvalwa, futhi imithambo yegazi inegazi elijwayelekile.

Imiphumela engajwayelekile ingabangelwa:

• Ukuvaleka emthanjeni ngegazi
• Ukuqina kwegazi emthanjeni (i-DVT)
• Ukunciphisa noma ukunweba umthambo
• Isifo se-arterial spastic (imithambo yegazi elethwa ukubanda noma imizwa)
• Ukuvaleka komzimba (ukuvalwa komthambo)
• I-venous reflux (ukugeleza kwegazi kuhamba ngendlela engafanele emithanjeni)
• Ukuvalwa komzimba okuvela ku-atherosclerosis

Lokhu kuhlolwa kungenziwa futhi ukusiza ukuhlola lezi zimo ezilandelayo:

• I-arteriosclerosis yemikhawulo
• I-thrombosis ejulile ye-venous
• I-thrombophlebitis engaphezulu

Azikho izingozi ezivela kule nqubo.

Ukubhema ugwayi kungashintsha imiphumela yalokhu kuhlolwa. I-nicotine ingadala ukuthi imithambo yegazi emaphethelweni iqine.

Ukuyeka ukubhema kwehlisa ubungozi bezinkinga ngenhliziyo kanye nohlelo lokujikeleza kwegazi. Ukufa okuningi okuhlobene nokubhema kubangelwa izinkinga zenhliziyo, hhayi umdlavuza wamaphaphu.

Isifo semithambo yegazi eseceleni - iDoppler; I-PVD - iDoppler; I-PAD - Doppler; Ukuvinjelwa kwemithambo yemilenze - iDoppler; Ukuhlukaniswa okuphakathi - iDoppler; Ukungasebenzi kahle kwemilenze - iDoppler; Ubuhlungu bomlenze nokuqunjelwa - iDoppler; Ubuhlungu benkonyane - iDoppler; I-Venous Doppler - DVT

• I-Doppler ultrasonography yomkhawulo
