Ultrasonography izitsha ubuchopho - izinkomba ngoba

Kubantu abaye ngaba nesifo sohlangothi, kubalulekile ukuba afeze semithambo ultrasound zobuchopho, ngoba unhlangothi is phetho ngqo izifo kwegazi e imithambo yegazi. It ofeza lokhu ngihlolwa kuzosiza udokotela wakho ukunquma ngokunembile ngaphezulu kungenzeka nesenzakalo unhlangothi yansukuzonke. Ultrasound imithambo cerebral bangase bachithe isikhathi esiningi njengoba ebekiwe udokotela, futhi nje ephendukela umtholampilo ezikhethekile. Futhi ngemiphumela ubheke onguchwepheshe.

Ngaphambi kokuba inhloko ultrasound kuyadingeka ukuze ukuqhuba ukuqeqeshwa abanye. Kuyinto snap, kodwa inikeza imiphumela esinembile ne ultrasonography imithambo palsy. Ezinsukwini ezimbalwa ngaphambi kwesifundo kubalulekile ukuzila ukudla, esithinta blood pressure. It is hhayi Kunconywa ukuba ngibheme phambi ultrasound okungenani ihora, kodwa okungcono Yiqiniso, okuningi.

Isikhathi esining impela, isifundo imithambo ubuchopho aphethwe kanye luhlolo izitsha entanyeni. Kuyinto lolu hlolo inikeza ulwazi oluphelele kakhulu igazi ebuchosheni, njengoba kwenziwe ekutadisheni liningi igazi ngokusebenzisa vertebral futhi subclavian lemithambo imithambo carotid kuphenyisiswe.

Ingqikithi yalo ultrasound izitsha ubuchopho ukuthi amagagasi ultrasonic edabula isitsha igazi ziyabonakala ngezindlela ezahlukene. It kuncike zenani izinga krovopotoka esitsheni ethile. Ngemva kwalokho, kubonakala amaza e-ultrasound ibe pulses kagesi babonisa esikrinini. Ngakho, udokotela angaba ngokushesha ubone disorder ischemic yegazi cerebral futhi kungacacisa ukuthi kahle lapho kukhona ukuvaleka yabo noma thrombosis.

Ngesikhathi luhlolo abavamile imithambo cerebral unganquma patency kuphela. Kodwa imishini zisenza sikwazi ukuba afeze izifundo ezinemininingwane eminingi. Ngokwesibonelo, ukuskena Duplex kakade usiza ukuhlola hhayi kuphela ijubane lokudlula igazi, kodwa futhi ukuze abone, ukuhlola umumo womzimba izitsha ngokwabo, futhi eyisitezi ukuskena futhi ngokunembile Kuhlola permeability yegazi, okuyinto uboniswa umbala imodi.

Ethwele UZDG izitsha ikhanda nentamo, unga:

- ukuhlola ukugeleza kwegazi velocity e yegazi yezingalo ikhanda nentamo;

- ukuze afeze kusenesikhathi yokuphazamiseka imithambo yegazi kubangelwa amahlule zingcwecwe atherosclerotic;

- izindawo ukukhomba vasoconstriction ;

- ukunquma ngokunembile kabanzi izimbangela ikhanda njalo;

- ukuze afeze ekuhlonzweni ka useshonile imithambo ingqondo.

Lapho-ke belulekwa ukuba ukuqhuba izitsha Doppler ultrasound ekhanda:

- uma umenzi izikhalazo ngesineke ikhanda njalo nokulahlekelwa ukwazi, khona umsindo ngaphandle ekhanda;

- ngenkulumo iziyaluyalu futhi ukuqala ngokuzumayo ukungabi namizwa izingalo nemilenze;

- uma izifo nesineke ezifana nomfutho wegazi ophezulu, pectoris angina, isifo cerebrovascular, isifo sikashukela kanye dystonia semithambo , kanye nezinye izifo ezingelapheki,

- ebukhoneni amazinga aphakeme cholesterol nokukhuluphala ngokweqile, futhi uma kwenzeka izinguquko igazi ekunqandeni;

- ntu are engaphezu kwengu-40 ubudala, ikakhulukazi uma eziseduze kufanele amacala kwaba ukufa uhlangothi, isifo senhliziyo, isifo sokuqina kwemithambo yegazi, umfutho ophakeme wegazi,

- njengoba lokhu inqubo kuyadingeka ngesikhathi kulungiselelwa isiguli ukuhlinzwa futhi ukuphumelela ukwelashwa kakade.

Ukuhlola izitsha kobuchopho ngokuphelele kobuhlungu futhi kuthatha cishe imizuzu engu-45 kuphela. Ngokushesha ngemva kwalokhu cwaningo isiguli Ungaphila impilo evamile. Ngemva lolo cwaningo ezandleni zakho imiphumela banikwa, okungase ukuqhaqha udokotela owayengifundela ultrasound, kodwa ngokuvamile bephathwa umuntu ekhishwe isiqondiso ucwaningo.
