Inkqubo yokujikeleza ingaphazamiseka ngenxa yokubunjwa kwe-thrombi, i-atherosclerosis kunye nezinye izifo zemithanjeni yegazi kunye nemithanjeni. Ukufumana ulwazi oluthe nkcukacha luza kwenza ukuba kube lula ukuxilonga. Ukwenza oku, i-ultrasound dopplerography imiselwe.
Le ndlela ibonisa isimo se-circulatory system ngexesha langempela, ngokuvelisa ulwazi olusisigxina kunye nolwahlulo kunye nokuqikelela izinga lokugeleza kwemifudlana ye-arterial and venous streams. Inkqubo ayikho into ephikisanayo kwaye ayibuhlungu ngokupheleleyo.
I-ultrasonic dopplerography yeempahla zephantsi
Uvavanyo lunokuba luyimfuneko ukuba kukho inkqubo yeenkqubo zokugulisa igazi kwinkqubo yokunikezelwa kwegazi, ngokubhekiselele ekungabikho kokungaqhelekanga kwiinqanawa, uyaphawula:
- ukuguqulwa kwemilenze rhoqo;
- intlungu ngexesha lokuhamba nokuhamba;
- ukuzithemba ngokungabikho kwezizathu ezibonakalayo;
- ubuthathaka bemilenze;
- ukuziva kubanda emilenzeni.
I-ultrasonic dopplerography yeempahla iya kuba yimfuneko kwizifo ezinjalo:
- I-Atherosclerosis, ngenxa yokutsalwa kweemitha ze-plaque kwiindonga.
- ukuphelisa i-endarteritis , ehamba kunye nokuvuvukala kwiimvini ezincinci kunye neempahla zonyawo kunye nomlenze ophantsi;
- isifo sikashukela, ngexesha apho i-atherosclerosis iphakanyiswa ngakumbi kwaye ayichaphazeli kuphela imirhobho enkulu, kodwa nayo i-capillaries.
I-ultrasonic dopplerography of veins of extremities
Ekubeni ubunzima beemvini zifakazela:
- ukuvuvukala;
- kubomvu kwesikhumba;
- Iimvumba ezandiswe ngaphandle;
- ukubonakala kwee-asterisks zamathambo;
- izilonda ezingahambi ixesha elide.
I-Dopplerography ikuvumela ukuba uvale ububanzi beemvini uze ubone ubukho begazi. Ugqirha ufumana ulwazi olungagcini nje ngeemvini kwiindawo, kodwa nangenxa enzulu ekhoyo (i-femoral, iliac, njl). Kule meko, ezi zifo zifumaneka:
- i-thrombosis, eyabangela ukugqithwa kwe-lumen yeemvini;
- i-varicose , eyenziwe njengesiphumo segazi.
I-ultrasonic dopplerography yeenqwelo ze-cerebral
I-UZGD kule meko imiselwe izigulane ezinengxolo ezindlebeni, i-opacity emehlweni, ukungazinzi, ukukhathala, utshintsho kwintsebenziswano kunye nomsebenzi onokukhubazeka. Ukusebenzisa inkqubo, unokukwazi ukuchonga:
- aneurysms;
- ukugawula imilambo yegazi;
- ezinye iziphazamiso zokuhamba kwegazi kwingqondo.
Ugqirha uvavanya amathuba okubetha kunye neengozi zeengxaki kwiindlela zokungenelela.
