Kushandisa ultrasound chirwere chisina kuvhara chinoshandiswa kuongororesa zvakadzama zvinokonzerwa nehutachiona (DVT) , mamiriro ezvinhu umo ropa rakave rakagadzirwa mumakumbo akadzika emugumbo. Kushandisa ultrasound kune zvimwe zvinobatsira pane zvimwe zvinongororwa zviratidzo zveDVT - zvinogona kuitwa nyore nyore munzvimbo dzakawanda, zvinopa migumisiro yakarurama, uye kune ngozi shoma inobatanidza nayo.
Kukosha kweDVT
Chirwere chemutsipa wemakumbo chinokonzera kusagadzikana kwemuviri, kudzivirira ropa kusadzoka nyore nyore kumwoyo. Somugumisiro, DVT inowanzotanga kubatanidza ropa muhudyu, kubereka marwadzo, kubwinya uye kuzvimba. Zviratidzo izvi zvinogona kuva zvisingaperi kana DVT isingatariswi zvakakwana.
Kunyanya kukosha, ropa rinoputika mumutsipa wemakumbo rinogona kusununguka uye kufamba kumapapu, zvichiita kuti kuve nemapapu. Mushonga wemapurmoni - iyo inofungidzirwa kuti inowanikwa pakati pe10% ne50% yevanhu vane DVT - yakaoma mamiriro ezvinhu anogona kuita kuti dyspnea yakaoma (kufema kufema), kusagadzikana kwemoyo uye rufu.
Nokuda kwechikonzero ichi, kana DVT ichifungidzirwa zvakakosha kuita chikonzero chekujekesa nokukurumidza sezvinobvira. Kurapa kwokutanga neanticoagulant zvinodhaka zvakakosha mukudzivirira mapurmonary embolus, kana (kana imwe yakatoitika) mukudzivirira imwe mishonga inoputika.
Compression Ultrasound
Munguva yakapfuura, kugadzirisa zvakajeka kweDVT kunofanirwa kuita shanje. Nechipupuriro, dhayi inorohwa mumutsipa wemakumbo, uye mifananidzo ye-x-ray inogadzirwa nedhayi inoyerera ichibva mumashure ichidzokera kumwoyo. Zvipingamupinyi zvikuru kumutsipa wemakumbo zvinogona kuonekwa. Ichi chiyero chinopisa chinogona kuva chinorwadza, nguva inopedza, uye chinosanganisira dzimwe njodzi, dzakadai sedambudziko rehutachiona.
Mune mamwe masangano, muedzo usingabvumirwi unonzi impedance plethysmography hunoshandiswa kuongorora DVT. Kunyange zvazvo chiyero ichi chiri chechokwadi, zvipatara zvakawanda hazvina zvigadzirwa kana unyanzvi hunowanikwa nyore nyore kuti zviite izvi.
Mumakore achangobva kupfuura, kushandiswa kwemaitiro e ultrasound kwakagadziriswa senzira inokurumidza, yakachengeteka, isingarwadziki, yakavimbika uye isingaoneki yekuongorora DVT. Munzvimbo dzakawanda dzakasimudza nhengo uye impedance plethysmography semuedzo wekutsvaga wekusarudza kweDVT.
Kumanikidzika ultrasound ndiko kuchinja kwemaitiro anowanzoshandiswa mune zvechiremba ultrasound (inozivikanwawo se "echo" test). iyo mafungu anonzwika anoshandiswa kumatawi achishandisa shanduro yakaiswa paganda, uye chifananidzo chemuviri pasi pechirangaridzo chinovakwa kubva kumhepo inodzoka mhepo. Nemhaka yokuti midziyo yekusvitsa ultrasound inowanikwa nyore nyore muzvipatara zvemazuva ano, uye nokuti nzira yekuita nayo iri nyore kudzidza, kukonzera ultrasound kwava nzira yekuenda kune dzimwe nzvimbo dzekuongorora DVT.
Kuti iite compress ultrasound, probe ye ultrasound inogadziriswa pamusoro pekufungidzira vein kuti ibudise mufananidzo we ultrasound wewaini. Munhu ari kuedza anoedza kumanikidzikisa mutsva nokuisungirira paine probe ye ultrasound.
Mitsemhere inowanzogadziriswa zvikuru; ndiko kuti, mitsetse inogona kudonha kwechinguva kuburikidza nekushandisa kushungurudzika kwavari. Uye zviri nyore kuona mupfungwa yekumanikidza kwevhein ne ultrasound.
Asi kana DVT iripo, kuvapo kweropa rinoita kuti zvive zvakaoma zvikuru kumanikidza musha. Apo mheta isinganzwisisiki, iyo inoratidza kuti DVT iripo. Iyo nzira inonzi ultrasound inogonawo kushandiswa kuedza kufungidzira chimiro chayo pachayo, uye kuongorora kubuda kweropa kuburikidza nemuviri kuti uone kana kuvhiringidzika kuri pachena. Zvisinei, kusakwanisa kugadziriswa kwemuviri ndiyo iyo inobatsira zvikuru pakudzidza mukuona DVT.
Mune chiitiko chekutsvaga kutsvaga DVT, kushandiswa kwemvere kunoshandiswa mune dzimwe nzvimbo dzakasiyana - chirume chechikadzi (munzvimbo yeguruva) uye mhuka yeplite (shure kwebvi). Zvidzidzo zvakaratidza kuti, uchishandisa nzira iyi yekunyora 2-dho, DVT inogona kunyatsoongororwa kupfuura 90% yenguva.
Nokuti inogona kuitwa nyore nyore munharaunda ipi zvayo yezvipatara, nokuti inopa migumisiro yakajeka, uye nokuti pane zvisingabatsiri, zvinokonzera ultrasound zvava kuedza kuongororwa kwesarudzo munzvimbo dzakawanda dzekuongorora DVT.
