I-Ultrasound yeempahla zentamo

Entanyeni kuninzi imithana yegazi, kuquka i-artery. Ngoko ke, ukuvavanya imeko karhulumente oogqirha bezempilo kukunika i-ultrasound yeenqanawa zomlomo wesibeleko. Ngethuba le nkqubo, unokuhlola isakhiwo seempahla, isivini kunye nesikhokelo sokuhamba kwegazi, kunye nokuchonga ubukho beendawo eziphazamisayo.

Imiqondiso ye-ultrasound yeempahla zentamo

I-ultrasound yeenqanawa zomlomo ingacwangciswa ngokupheleleyo kubo bonke abantu. Oku kuya kukunceda ukunciphisa amathuba okubonakala nokuphuhliswa kwesifo sobomi. E mngciphekweni:

• abantu abangaphezu kweminyaka engama-40 ubudala;
• abantu abane-diagnostic diabetes mellitus;
• abantu abane-cholesterol ephakamileyo, i-triglycerides, i-lipoproteins kunye neqondo eliphantsi kwegazi;
• kuxhomekeke kwi-nicotine;
• izigulane eziphezulu;
• abantu abane- osteochondrosis yesebe lomlomo wesibeleko .

Esinye isizathu sokucwangciswa kwe-ultrasound yeempahla zentamo kungenziwa utyando lwentliziyo okanye imithwalo yegazi. Kukho iqela lezikhalazo ezingabonisa ukukhubazeka kweengculazi:

• ukuhamba ngokukhawuleza;
• rhoqo utywala;
• ukukhala okanye ingxolo ezindlebeni ;
• kulala;
• ukuwohloka kombono;
• ukukhubazeka kokuva;
• intloko.

Yiyo le mpawu engasebenza njengesizathu esinzima se-ultrasound yesebe yomlomo wesibeleko.

I-ultrasound yeempahla zentamo?

Ingundoqo yesifundo ngasinye se-ultrasound kukuba izicubu zomzimba zibonakaliswa ngamadiresi ahlukeneyo okumelana no-acoustic; Ngenxa yoko, imifanekiso emnyama neyemhlophe idalwe, enceda ukuhlola imeko yelungu okanye isayithi ehlolwayo.

Namhlanje, xa uhlolisisa isebe lomlomo wesibeleko, ukukhangela kwe-duplex kusetyenziswa ngokuqhelekileyo endaweni ye-ultrasound yendabuko. Olu hlobo lwesifundo lubonisa amaza aphezulu avela kwizinto ezihambayo, avumela ukuvavanya imeko yazo zonke iinqanawa zomlomo wesibeleko, ubukho be-constriction, thrombosis, kunye nejubane kunye nesikhokelo sokuhamba kwegazi.

Ngaphambi kokuba usebenzise i-US kuyimfuneko ukuba ususe okanye uthathe iingubo kunye neempahla kwintsimi yentamo. Uviwo luya kwenziwa ngokubini kwindawo yesigxina kunye nendawo yokuhlala. Konke kuxhomekeke kwindawo yentamo efuna ukuhlolwa. Ngokuqhelekileyo phambi kwe-ultrasound ugqirha unomdla kwiimeko zakho, ubukho bezikhalazo kunye nokuphonononga imbali yonyango, kuba uvavanyo oluchanekileyo kufuneka lukwazi yonke imifanekiso yeklinikhi.

Uphando olongezelelweyo lwenziwa ngolu hlobo lulandelayo:

1. Ulusu lusetyenziswa nge gel evulekileyo, enika uxhapha olusondeleyo ulusu kunye nenzwa yesipilisi se-ultrasound.
2. Emva kokuba uqhagamshelwano luqulunqwe, ugqirha uyayicoca ngokukhawuleza imifanekiso emnyama nemhlophe eguquka kwisantya, ebizwa ngokuba "iinqununu". Kwisifundo, isenzi sinokuvelisa izandi ezibangelwa ukulinganisa ukuhamba kwegazi kwisitya.
3. Emva kokuba ugqirha azibonele ulwazi oluyimfuneko, uviwo luphela. Igcina idatha kwaye iprinte ikopi enye. Kule ndlela i-ultrasound ingaqwalaselwa ingagqibekanga.

Ukumiswa kwe-ultrasound yeempahla zentamo

Xa uphando ukuba kubalulekile ukwazi ukuba yintoni ebonisa i-ultrasound yeempahla zentamo, kodwa kwakhona unokukwazi ukucacisa umphumo. Oku kuya kukunceda wenze ulwazi malunga nezikhombisi ezifunyenweyo:

1. Ngoko, makhe siqale nge-artery carotid. Ubude bayo ukuya ngasekunene ngu-7 ukuya kwi-12 cm, ukuya kwesobunxele-10-15 cm. Kwiimeko ezinqabileyo, xa uqhuba i-ultrasound yemithwalo yentamo kuthathwa njengesiqhelo ukufumana umzobo omnye kuphela. Umlinganiselo we systolic-diastolic kufuneka ube ngama-25-30%. Oku kuthathwa njengesiqhelo.
2. Inqanawa elandelayo ebalulekileyo yintsimbi ye-vertebral. Kuyo, ukuhamba kwegazi kufuneka kuqhutywe phambili, ezinye iindidi zibhekwa njengophambuko.
3. Ngokubhekiselele kumjikelezo wegazi, umlinganiselo phakathi kokujikeleza kwegazi kwi-carotid kunye ne-internal carotid artery kufuneka ibe ngaphakathi kwe-1.8 ± 0.4. Ubungakanani bomlinganiselo buchaphazela ubunzima be-spasm kwiinqanawa: enkulu inqanaba, elona likhulu.

E-US yeenqanawa zomlomo we-thyroid gland kufuneka ibe nohlobo oluthile oluphandwayo:

• ngobunzima be-gland - 15 - 20 mm;
• ububanzi - 20 - 25 mm;
• ubude - 30 - 50 mm.

Ezinye izalathisi aziqwalaselwe njengesiqhelo kwaye zibonisa ukungahambi.
