Duplex ziwiya chindodo

Duplex chindodo ziwiya ndi njira zofufuzira zimene Chili Doppler jambulani (ultrasound) ndi ultrasound chikhalidwe. njira yodziwira zimathandiza adokotala kuona dongosolo la kachitidwe mtima. Akupanga kulingalira mu mode pano limachititsa amati boma la mpanda chotengera, kupenda magazi mu mfundo yeniyeni lumen wa. Duplex mtima jambulani ambiri kumatenga makumi atatu ndi makumi mphindi zisanu.

Kupezeka ndi lolondola kufufuza njira kuchuluka ndi ntchito utoto wa mitundu yosiyanasiyana chizindikiro. Choncho, anatsimikiza mathamangidwe ndi malangizo a magazi. Zona ziwiya duplex chindodo ndi minofu ozungulira mu mode B. Imodzi, kuphunzira magazi ambiri lumen ndi mtima ntchito Doppler zotsatira mwa mtundu 'kala' ikusonyeza kapena kusanthula kawalidwe. Zotsatira zake zingakhale kapena mtundu cartogram kusonyeza otaya ndi Doppler sipekitiramu. Cartogram lachokera ku mtima lumen 'akuponyedwa. " Malinga ndi iye angioneurology tingadziwire pamaso pa kupatuka aliyense pa njira yachibadwa (mapindikidwe, crimp, etc.) popanda vuto. Kuzindikiritsidwa ndi kusintha mu lumen mtima (magazi kuundana, zolengeza, etc.). Yodziwika Doppler sipekitiramu kufalitsa otaya, pamene akugwiritsa ntchito zina mawerengedwe akalozera imatheka molondola kwambiri kuunikira chikhalidwe cha kudwala lapansi.

Duplex ziwiya chindodo zimathandiza akatswiri amanena ndi udzakhalire boma la magazi m'madera ambiri a dongosolo mtima. Research amenable yaikulu motani zazikulu ndi zazing'ono subkutannye (subcutaneous) ndi nthambi limba magazi.

M'zotengera lalikulu zotheka mwamtheradi kuti muzione kusintha kulikonse pa khoma chotengera pa magawo oyambirira a matenda, monga matenda ashuga angiopathy, nestenoziruyuschem atherosclerosis. N'kosavuta makamaka, ndi matenda a zotupa kugwirizana ndi matenda osiyanasiyana ndi kusintha intraluminal (magazi kuundana, atherosclerotic mipukutuyi), ndi permeability chatsitsa. Kupeza bwinobwino amalola matenda molondola mkulu ndiponso kudalirika. Zimenezi, kumathandiza kuti kusankha moyenera machenjerero achire, kulungamitsa kufunika kwa alowererepo pa opaleshoni.

Mu kuphunzira ziwiya ka magazi, kuphatikizapo wapotalikira mitsempha zotumphukira ndi mitsempha, chifukwa kakakulu ka khoma mtima, lathu zimaonetsa mtima zowonera ali mokwanira otsika khalidwe. Chifukwa, ndi ziyenera odalirika kusintha malinga ndi skylight ndi sizingatheke. Pa nkhani imeneyi, kuphunzira limati ziwiya yaing'ono likungosonyeza kutsogolera udindo wa deta ya modes ndi Doppler - kawalidwe ndi mtundu. Ntchito mode mtundu akhoza isanafalikire chinthu kulingalira zotsatira chifukwa lumen ake, komanso kuunikira malo malinga ndi mbali anatomical ndikupeza mavuto.

Duplex chindodo ziwiya mutu ndi khosi amapereka awiri ooneka enieni chithunzi ndi nkhani omveka ndi mwatsatanetsatane m'magazi. phunziro limapereka mwayi woti muone awiri mtima ndege. Duplex chindodo ziwiya khosi ntchito matenda a pathologies occlusive-stenotic carotid mitsempha (kulemala oziziritsa magazi okwanira).

Pali malo angapo kuphunzira pamwambapa. Ambiri monga

- DS GCA (phunziro brahiotsefralnyh mitsempha) kapena DS magazini (kuyang'ana mitsempha yaikulu ya m'mutu);

- TKDS (transcranial kafukufuku);

- duplex kupanga sikani ya mitsempha ndi mitsempha ya m'makona, mwana wa diso ndi zina.
