Duplex chindodo ku matenda a matenda mtima

Duplex chindodo ndi osakaniza ochiritsira ultrasound maphunziro (B-mode) ndi luso ndi Doppler kudziwa magazi ndi krovoottoka. Chotero kuwaphatikiza kwambiri ogwira njira matenda mu angiology ano.

Duplex chindodo mu phlebology chimaonedwabe "golide muyezo". Modern phlebology pafupifupi milandu ntchito njira imeneyi kwa matenda. Duplex kupanga sikani ya mitsempha amathandiza udzakhalire vasculature kwa Tambasula kwambiri, boma kayendedwe ka magazi mwa iye. Kugwiritsa ntchito njira imeneyi n'kofunika kuti matenda, komanso zochizira ndi madokotala ananena zawo za matenda venous osati.

Pali njira zosiyanasiyana kuchita njirayi. Kuphimba njira zimathandiza kudziwa chabe mfundo zikuluzikulu, pang'ono diagnostics zachipatala ultrasound popanda kufufuza mtima pa phlebologist angapereke mwatsatanetsatane khalidwe mtsempha chikhalidwe. Atumizidwa kwa nthawi yochepa kafukufuku, pafupifupi mphindi 10 Mwachitsanzo, duplex kupanga sikani ya nthambi m'munsi (zonse!) Kodi kutenga mphindi 40-50. Pakuti venous kudwala mosamala angagwiritsidwe ntchito ultrasound: timatha inu kuti muzikhala ndi bottlenecks, amene kenako zina kufufuza pamene duplex chindodo.

kafukufuku More mwatsatanetsatane ndi nkhani ndi sekondale duplex chindodo, pambuyo kuyendera-phlebologist dokotala amene osonyeza mafunso zofunika kuthetsa ndi kulongosola. Ngati njirayi ikuchitika asanayambe ulendo wake, nthawi zambiri zofunika kubwereza kukhazikitsa monga pa phwando pa phlebologist kuoneka nkhani osathetsedwa.

Pa phwando, choyamba kuyendera mapazi kudziwa malo akufunika chisamaliro chapadera. Ndipo anayendera ayenera kuchitidwa mu malo supine (yabwino anawona kwambiri mtsempha), ndipo mu malo ubwenzi (Pankhaniyi - pamwamba). Ndi kachipangizo ndi anayendera iliyonse miyendo centimeter. preclinical magawo Pali matenda, zimene yekha titsimikize mothandizidwa ndi ultrasound.

m'munsi nthambi venous dziwe zikuphatikizapo 26 mitsempha mbali iliyonse. kusintha pafupipafupi ali pa matenda a mitsempha ya phazi.

Monga tanena duplex chindodo tichipeza osakaniza ndi akupanga B-mode ndi Doppler. Zipangizo B-mode ultrasound zimatulutsa pafupipafupi ena kuti likulowerera mwa nsalu. osiyana kachulukidwe minofu malire amachititsa ultrasound zimaonekera ndi kubwerera ku sensa. kachipangizo Izi zimathandiza zimachitika. Kwakukulu mtunda pakati pa kachipangizo ndi m'mphepete, nthawi zambiri akudutsa pa ultrasound cheza mpaka adani ake. Choncho, pali chindodo awiri azithunzi omwe tikunena ndi kukhazikitsanso ziwiya mayeso. Doppler potengera mmene yemweyo: ultrasound kugunda anasamutsa particles osati zimaonekera, komanso kumasintha pafupipafupi, kusintha kwa chizindikiro ichi ndi njila kwa mathamangidwe wa chinthu chokwawa. Mu kuphunzira mtima zopezera kusuntha zinthu - maselo ofiira a magazi. Pa gawo lino n'zotheka kumanga mtundu cartograms otaya mu chotengera, amene ndiyotengera ndi mphamvu ndi chitsogozo cha magazi ntchito mtundu. Njira - mtundu Doppler sanjira.

Ndi modes awiriwa ingatithandize kudziwa za thunthu mtima, chikhalidwe cha nyumba yawo ndi lumens, kuonanso kusintha iwo, younikira kusintha hemodynamics. Komanso njira iyi si olanda, komanso amalola matenda ambiri matenda mtima.
