Duplex kushanda pakuvheneka midziyo

Duplex kushanda pakuvheneka midziyo ndiyo nzira kutsvakurudza anosanganisa Doppler Ongororo (Ultrasound) uye zvetsika Ultrasound. Nzira iyi chirwere rinobvumira chiremba kuona nemamiriro vascular hurongwa. Ultrasonic kuri muna chipo rudzi runoita kufungidzira mamiriro ezvinhu mudziyo rusvingo, kuongorora ropa riyerere munzira nezverimwe ari lumen. Duplex vascular Ongororo yemanyorero kwazvinogumira matatu kusvika makumi mana nemaminitsi mashanu.

Kuwanikwa uye rakarurama tsvakurudzo nzira kuwedzera nokushandiswa ruvara coded chiratidzo. Saka, kutsunga velocity uye achitungamirirwa ropa kuyerera. Zvinoshanda duplex kushanda pakuvheneka midziyo uye yakapoteredza zvinyama ari B muoti. Panguva imwe chete, kudzidza ropa riyerere ari vascular lumen chichishandisa Doppler maturo kuburikidza ruvara Coding kana spectral kuongorora. Zvinogona kana munhu ruvara cartogram kuratidza kuerera uye Doppler chakarondedzera. Cartogram rinobva vascular lumen "akakandwa." Maererano kwaari angioneurology anogona kuona kuvapo chero yakatsauka kubva chakaipa kosi (deformation, crimp, etc.) pasina dambudziko. Kuzivikanwa uye kuchinja vascular lumen (clots ropa, Dombo, etc.). Ichazivikanwa Doppler chakarondedzera kuparadzirwa aibuda, kana uchishandisa mamwe kukarukureta indices zvava zvinogoneka zvakarurama vaongorore yezvakaita zvokurwara.

Duplex kushanda pakuvheneka midziyo achibvumira nyanzvi dzinofungidzira uye kuona mamiriro ropa riyerere munzira dzakawanda vascular hurongwa. Research amenable huru sei chikuru uye diki subkutannye (subcutaneous) uye bazi nhego ropa.

In huru nenhumbi zvachose zvichiita kuti vafungidzire chero kuchinja mudziyo wall vekare nzendo chirwere, akadai chirwere cheshuga angiopathy, nestenoziruyuschem atherosclerosis. Hazvina kunyanya kuoma, uye chirwere ane maronda chokuita zvinetso zvakasiyana-siyana uye intraluminal kuchinja (ropa clots, atherosclerotic plaques), kuti permeability kuipa. Kuwana Kunyatsoona unokubvumira rokuongorora dzakakwirira zvakarurama uye rakavimbika. Izviwo, zvinoita kuti zvakakodzera kusarudzwa kuchirapa nzira, mururamisire kudiwa kuvhiya kupindira.

Kudzidza duku midziyo ropa, kusanganisira distal peripheral mutsinga uye arteries, nokuda duku ukobvu ari vascular rusvingo, dzidziso yepasi vascular Visualization ane zvakakwana kbps. Somugumisiro, akavimbika tinyatsonzwisisa kuchinja masvingo uye skylight zvisingaiti. Panyaya iyi, pakudzidza rinoti duku caliber midziyo vaitungamirira basa ndohwaJehovha umboo pamusoro Doppler modes - spectral uye ruvara. Uchishandisa ruvara muoti inogona vemunyika chinhu kuri mugumisiro nokuda lumen ayo, uyewo kuyera nzvimbo maererano anatomical zvinhu uye kuziva epfungwa.

Duplex kushanda pakuvheneka romusoro uye mutsipa midziyo inopa mbiri-dimensional mufananidzo pamwe yakajeka uye hwakadzama mashoko muropa. Kudzidza uku zvinopa mukana kuona vascular ndege mbiri. Duplex kushanda pakuvheneka rwengarava mutsipa zvaishandiswa nechirwere pamusoro pathologies occlusive-stenotic carotid arteries (vasingadzoreki chepfungwa ropa zvitengeswa).

Kune nzvimbo dzinoverengeka dzokudzidza pamusoro. Rakajairika vanosanganisira

- DS GCA (yokudzidza brahiotsefralnyh arteries) kana DS mag (kushanda pakuvheneka arteries zvikuru musoro);

- TKDS (transcranial tsvakurudzo);

- duplex kushanda pakuvheneka of mutsinga uye arteries wamativi, yeziso nezvimwe.
