Doppler ultrasound imilenze asezantsi: amaqhinga ukufunda. Izinto ezibonisa ukuba inkqubo

Ezininzi iingxaki kunye nemilenze, ngenxa ukuphazamiseka kwegazi. Ngapha koko, xa ukwehla aliyi kubonelela igazi ukugeleza ukuya emilenzeni. Ukuze ufumanise ukuba oonobangela esakhokelela ekubeni ezi iintshukumo zokwaphulwa kwemithetho ziya Doppler ultrasound kweqondo asezantsi.

Ezibonisa luhlolo

Doppler ultrasound yenye yeendlela ezininzi ezisebenzayo zoviwo leyo ukuxilonga thrombosis lwemithambo, kuquka kwi amacala asentla emilenzeni, yegazi kunye nezinye izifo.

Kukho uluhlu kwakuthethwa apho ultrasound Doppler kwemithambo ngemithambo kweqondo kufuneka kwenziwe ngaphandle nakanjani. Ezi ziquka:

- rhoqo izihlunu cramping umlenze;

- elivela kuzo iintlungu ezinxulumene ne umthwalo dystrophy;

- imilenze ekweneni iinyawo;

- ukubonakala imithambo gqitha, spider imithambo;

- komzimba umzimba angamanga;

- ivela ngamaxesha ngesiquphe claudication;

- ngokukhawuleza asakhulayo imvakalelo ubunzima imilenze;

- non-ephilisa izilonda kunye notshintsho ezahlukeneyo trophic;

- isikhumba owomileyo, ukutshintsha umbala walo;

- deformation le phalanges;

- imithambo throbbing umlenze ngokulambisa ebonakalayo okanye ezingabonakaliyo ngokupheleleyo.

Xa ezi mpawu kubalulekile isifo kwangethuba. Oku kuya kuvumela ixesha ukuchonga isifo kwaye ukumisela unyango olufanelekileyo.

Izizathu ezinokwenzeka ukuphazamiseka kwegazi

Kukho uluhlu olude ebanzi ezinokuphembelela kunokubangela iingxaki kwegazi. It Doppler ultrasound kweqondo ephantsi ukugqiba ngxaki ngqo.

Ngoncedo zophononongo zibonisa:

- ngemithambo Varicose: kwiindawo ezithile zibonwa iinkqubo amile;

- thromboembolism pulmonary: on Doppler ultrasound iya kwenziwa ibe egazi igazi imithambo nzulu, kukuba kunyanzelekile ukuba iimviwo lung kule sifo;

- thrombosis, okukhokelela insufficiency lwemithambo: on dopplere lubonisa ukuba iibhloko ihlwili inqanawa.

Kuzo zonke ezi meko igazi ngenkankulu udlula iimpahla. Doppler ultrasound kweqondo ephantsi sikuvumela ukuba ubone kwiindawo ezininzi iingxaki. Olu vavanyo ikuvumela ukuba ukumisela endarteritis kunye yamafutha emilenzeni, ukuchonga thrombosis kunye thrombophlebitis, angiopathy in seswekile. Ngapha koko, ezi zifo kukhokelela ukuphazamiseka kwegazi igazi yesiqephu asezantsi.

Ithekhinoloji inkqubo

Oogqirha abaninzi bathi musa kudinga ekhethekileyo phambi Doppler ultrasound kweqondo asezantsi. Ntoni na, kukuba bayakwazi ukuchaza phlebologist okanye ugqirha nemithambo. Noko ke, kucetyiswa ukuba ayeke esela iziselo ezakhayo (iti okanye ikofu onamandla), ukutshaya kunye imithi ezithile.

Kuphando apha emilenzeni ukuchaza izahlulo ulawulo eziliqela, apho iimpahla kudlule kufutshane nolusu. Kulo mhadi emva kwedolo, isikhumba kummandla isondo inguinal, ngaphakathi neqatha. Kwakhona, njengokuba ulawulo ngokuthatha isiza apho saphenous Vienna omkhulu kufuneka ifakwe ethangeni.

Ekuqaleni, isigulana ubuxoki emqolo, ngoko isicelo likagqirha eziwela ngaphaya.

Kudla kubanjelwa uphando imile. Kulo mzekelo, isigulane kufuneka wenze iimvavanyo ezininzi ezithile zokuxilonga, ukukhohlela. Oku kwenza kube lula ukuba bahlole igazi flow emithanjeni ezahlukeneyo.

Izinto eziluncedo ze-scan Doppler

Olujikeleza Doppler ultrasound kweqondo olusezantsi indlela ekhuselekileyo kwaye ulwazi kakhulu ukuvavanya ukuhamba kwegazi. Ingasetyenziswa kuphela ukufumanisa isifo, xa ukuhamba kwegazi kuphazamisekile kakhulu, kodwa ukufumanisa ekuqaleni sifo ngxexesha apho naziphi na iimpawu zonyango bengekho.

Le ndlela isekelwe kwinto yokuba yomtshangatshangiso cuke kubonakala ukuba ihamba izinto. Oku lutshintsha rhoqo uphawu ofakwe. Ukusebenzisa Doppler ultrasound uyakwazi ukubona apho zokwalatha oko isantya ihamba ngegazi, funda stenosis atherosclerotic, khangela pulsation. Kwakhona, le ndlela ivumela ukuba uqikelelo ngcaciso ukuhamba kwegazi uchonge iimpahla ivalekile. Nalo khangela ngendlela akananto kwegazi.

Kodwa ezifundisayo kakhulu ukukrwaqula kabini, apho ngaphandle ultrasonography oluqhelekileyo wenze ultrasound. Kunye indlela yamva, uyakwazi ukubona iimpawu yokwakheka lobume nemithambo.

Oko bonana nogqirha ngexesha le nkqubo

Ngexesha ultrasonography kweqondo zeengcali okungenzimanga ukuchonga komgomo ezithile. Uphononongo lunika ithuba ukuqonda ukuba yintoni eyenzekayo imithambo yegazi, kunye nokuseka ukuxilongwa. Ngenxa yoko, ngexesha uhlolo, unga:

- khangela ukuba utshintsho ukubetha lokutshangatshangisa;

- kuhlola lehla igazi flow kwezinye iindawo;

- ukubona ukuba igazi lazo;

- waphawula igazi ukuhamba retrograde kwixesha ukuphumla, okanye, icala, imithwalo;

- ukubona utshintsho iqatha brachial Isalathisi: sisalathiso ebalwa ngokususela lulwahlulo xi ngemithambo umlenze kufutshane amaqatha kunye brachial kwemithambo;

- waphawula ukuba kukho kukhululeka okungaqhelekanga igazi ngenxa perforating mithambo;

- kukho ukuhla phezu isitya igazi-uxinzelelo efanayo.

Elinye okanye ngaphezulu iimpawu zophendlo lwezifo ukuvumela ugqirha ukuseka isifo. Ukuba kuyimfuneko, yingcali sinokusetyenziswa isigulane ukuba uviwo olunye.
