Duplex kushanda pakuvheneka iri nechirwere pamusoro vascular chirwere

Duplex kushanda pakuvheneka kunosanganisira munhu kwakajairika Ultrasound zvidzidzo (B-rudzi) pamwe Doppler mitoo kuziva ropa kuyerera uye krovoottoka. Kubatana kwakadaro ndiko zvikuru anobudirira nzira nechirwere mu angiology ano.

Duplex kushanda pakuvheneka mu phlebology ichaongororwa ndiyo "nzira yemandorokwati". Modern phlebology kazhinji kacho vachishandisa unyanzvi izvi nechirwere. Duplex kushanda pakuvheneka of mutsinga kunobatsira kuona vasculature kuti chinokosha tatamuka, kunyoresa sangano ropa mairi. Tichishandisa nzira iyi haisi chete anodiwa nechirwere, asiwo mishonga uye fungidziro pamusoro venous zvirwere.

Pane nzira dzakasiyana-siyana kuti vanoita nzira iyi. Kuongorora nzira kunoita kuona chete huru nyaya, shoma yezvokurapa Ultrasound Diagnostics pasina kubvunza murwere ari phlebologist anogona kupa hwakadzama noruzhinji tsinga ezvinhu. Akatumirwa shoma nguva imwe ongororo yakaitwa, vanenge 10 maminitsi Somuenzaniso, duplex kushanda pakuvheneka repasi Mbabvu (zvizere!) Vanofanira kutora maminitsi 40-50. For venous zvokurwara kuongorora zvinogona kushandiswa Ultrasound: kunobatsira iwe kuronga bottlenecks, iyo inogona mberi Akaongorora kana duplex kushanda pakuvheneka.

More hwakadzama uye anodzidzisa tsvakurudzo hakukoshi duplex kushanda pakuvheneka, pashure kushanyira-phlebologist chiremba uyo Ichatibatsira mibvunzo zvakakodzera kugadzirisa uye kujekesa. Kana nzira iri kuitwa asati kushanya, kazhinji zvakakodzera kudzokorora Implementation kwayo sezvazvakaita panosvikira pa phlebologist ngapaonekwe zvisingagadziriswi nyaya.

Pamabiko, tanga kuongorora tsoka kuziva nzvimbo vanoda kutarisirwa. Uye rokuongorora yaifanira ari supine nzvimbo (zvakanakisisa kumboona yakadzika tsinga), uye ari akamiswa (mu iyi - pemvura). Tiine Switch iri iongororwe makumbo ose sendimita. preclinical Pane nzendo chirwere, izvo chete inogona tsunga tichibatsirwa Ultrasound.

repasi muzvidimbu venous dziva rinosanganisira 26 mutsinga kurutivi rumwe norumwe. Kakawanda kuchinja vari zvirwere mutsinga norutsoka.

Sezvataurwa pamusoro apa, duplex kushanda pakuvheneka inoumbwa mubatanidzwa ane ultrasonic B-rudzi uye Doppler. The B-rudzi Ultrasound mano emit imwe maitikiro kuti chinopinda kubudikidza jira. siyana arambe achirema rinenge muganhu kunokonzera Ultrasound kunooneka uye kudzokera shure kune Switch. Switch ichi inoshanda kufamba kweropa. The mukuru kure pakati Switch uye kumucheto, zvikuru nguva inopfuura kubva Ultrasound nemwaranzi kusvikira kubatwa kwayo. Saka, pane vaviri-dimensional kushanda pakuvheneka uye vavakezve bvunzo midziyo. Doppler kwakavakirwa zvimwechetezvo: Ultrasound kudhumhana pamwe kutamira nezvimedu kwete chete airatidza, asiwo alters kakawanda, shanduko parameter iri Proportional kuti velocity ari zvinofamba chinhu. In kudzidza vascular samambure kutamira zvinhu - dzvuku masero eropa. Panguva ino Danho zvinobvira kuvaka ruvara cartograms aibuda mune mudziyo, izvo encoded kubudikidza kusimba uye kutungamirirwa ropa kuyerera uchishandisa ruvara. Nzira iyi - a ruvara Doppler Mapping.

With izvi modes mbiri inogona ruzivo pamusoro vascular anatomi, nemamiriro avo masvingo lumens, kuongorora kuchinja pavo, kuti chamber kuchinja hemodynamics. Uyezve, nzira iri dzisiri invasive, uye inokupai iwe rokuongorora vakawanda vascular chirwere.
