Ntau yam teeb meem nrog rau sab qis tshwm sim vim muaj kev cuam tshuam ntawm cov hlab ntshav. Tseeb tiag, nrog rau nws qhov kev puas tsuaj, nws yuav tsis tuaj yeem ua kom cov ntshav txaus rau ob txhais ceg. Txhawm rau kom paub qhov laj thawj uas ua rau muaj kev ua txhaum cai no, ultrasound ntawm cov leeg ntawm cov leeg qis yuav pab tau.
Indications rau kev xeem
Doppler ultrasound yog ib txoj hauv kev zoo tshaj plaws uas tso cai rau koj los kuaj xyuas cov hlab ntsha, suav nrog hauv ob txhais ceg, obliterating atherosclerosis thiab lwm yam kab mob.
Muaj ib daim ntawv teev cov cim qhia tias ultrasound ntawm cov hlab ntsha thiab cov hlab ntsha ntawm cov extremities yuav tsum tau ua yam tsis muaj kev poob. Cov no suav nrog:
- cov leeg mob ib ce;
- pom qhov mob thaum lub cev tawm dag zog;
- loog thiab o ntawm ob txhais ceg;
- qhov pom ntawm cov leeg deformed, kab laug sab leeg;
- ua rau tsis muaj qhov tsis zoo ntawm lub cev;
- qee zaus sudden lameness;
- tshwm sim sai sai ntawm ob txhais ceg hnyav;
- tsis kho qhov txhab thiabntau yam kev hloov pauv trophic;
- daim tawv nqaij qhuav, tawg;
- deformity ntawm phalanges ntawm tus ntiv tes;
- NW nyuam qhuav pom lossis tsis pom tseeb ntawm cov hlab ntsha ntawm ob txhais ceg.
Thaum cov paib no tshwm sim, nws yog ib qho tseem ceeb uas yuav tau kuaj xyuas raws sijhawm. Qhov no yuav tso cai rau txheeb xyuas tus kab mob raws sijhawm thiab sau ntawv kho kom txaus.
Yuav ua rau muaj kev tsis zoo
Muaj ntau cov npe ntawm yam uas tuaj yeem ua rau cov hlab ntshav tsis zoo. Nws yog ultrasound ntawm cov leeg ntawm cov leeg qis uas tso cai rau koj los txiav txim siab qhov teeb meem.
Tshawb nrhiav nthuav tawm:
- varicose leeg: cov txheej txheem stagnant pom nyob rau hauv qee qhov chaw;
- pulmonary thromboembolism: ultrasound yuav pom cov ntshav txhaws hauv cov hlab ntsha sib sib zog nqus, nrog rau tus kab mob no yuav tsum tau kuaj lub ntsws;
- thrombosis ua rau venous insufficiency: Doppler qhia tias cov thrombus thaiv lub lumen ntawm lub nkoj.
Txhua qhov xwm txheej no, cov ntshav tsis dhau los ntawm cov hlab ntsha. Ultrasound ntawm cov hlab ntsha ntawm qis extremities tso cai rau koj pom cov teeb meem feem ntau. Qhov kev kuaj no tso cai rau koj los txiav txim siab endarteritis thiab atherosclerosis ntawm ob txhais ceg, txhawm rau txheeb xyuas thrombosis thiab thrombophlebitis, angiopathy hauv ntshav qab zib. Tom qab tag nrho, cov kab mob no ua rau cov hlab ntsha hauv qis qis.
txheej txheem thev naus laus zis
Ntau tus kws kho mob hais tias tsis muaj kev npaj tshwj xeeb ua ntej ultrasound ntawm cov leeg ntawm sab qis. Dab tsi yog nws, tus kws kho mob phlebologist tuaj yeem piav qhia zoo tshajlos yog angiosurgeon. Txawm li cas los xij, qee qhov qhia kom tsis txhob haus cov dej qab zib uas txhawb zog (cov tshuaj yej muaj zog lossis kas fes), haus luam yeeb thiab noj qee yam tshuaj.
Thaum ua kev ntsuam xyuas ntawm ob txhais ceg, ntau qhov chaw tswj tau txiav txim siab uas cov hlab ntsha hla mus ze rau ntawm daim tawv nqaij. Qhov no yog lub qhov nyob rau hauv lub hauv caug, daim tawv nqaij nyob rau hauv lub cheeb tsam ntawm lub inguinal folds, lub puab ib feem ntawm pob taws. Tsis tas li, raws li kev tswj hwm, coj thaj chaw uas cov hlab ntsha loj saphenous yuav tsum ntws mus rau hauv femoral.
Ua ntej, tus neeg mob pw ntawm nws nraub qaum, tom qab ntawd, ntawm qhov kev thov ntawm tus kws kho mob, tig rau ntawm nws lub plab.
Ib feem ntawm kev xeem yog ua nyob rau hauv ib qho chaw sawv. Hauv qhov no, tus neeg mob yuav tsum ua qee yam kev kuaj mob, hnoos. Qhov no tso cai rau koj los ntsuas qhov ntws ntawm cov leeg sib txawv.
Cov txiaj ntsig ntawm Doppler scanning
Ultrasound ntawm cov hlab ntsha ntawm cov hlab ntsha ntawm cov leeg qis yog ib txoj hauv kev nyab xeeb thiab qhia tau zoo rau kev ntsuas ntshav. Nrog nws cov kev pab, koj tuaj yeem tsis tsuas kuaj tus kab mob thaum cov ntshav khiav tsis zoo, tab sis kuj txiav txim siab qhov pib ntawm tus kab mob nyob rau theem thaum tsis muaj cov tsos mob tshwm sim.
Tus qauv yog raws li qhov tseeb tias lub yoj ultrasonic tau cuam tshuam los ntawm cov khoom txav. Qhov no kuj hloov qhov zaus ntawm lub teeb liab tso zis. Nrog kev pab los ntawm ultrasound, koj tuaj yeem txiav txim siab nyob rau hauv qhov kev taw qhia thiab ntawm qhov ceev ntawm cov ntshav txav, saib atherosclerotic stenosis, kuaj lub pulsation. Tsis tas li ntawd, txoj kev no tso cai rau koj los ntsuas cov ntshav ntws hauv feeb thiab txheeb xyuas cov hlab ntsha txhaws. Siv nws los kuaj xyuas kev ua haujlwmcollateral ncig.
Tab sis cov ntaub ntawv tshaj plaws yog kev kawm duplex, uas, ntxiv rau ultrasound, ib qho kev ua ultrasound kuj ua tiav. Siv cov txheej txheem tom qab, koj tuaj yeem pom cov yam ntxwv ntawm lub cev ntawm cov qauv ntawm cov hlab ntsha.
Tus kws kho mob pom dab tsi thaum lub sijhawm txheej txheem
Thaum ua ultrasound ntawm cov leeg ntawm sab qis, tus kws kho mob tuaj yeem txheeb xyuas qee yam kab mob. Txoj kev tshawb no ua rau nws muaj peev xwm nkag siab tias muaj dab tsi tshwm sim nrog cov hlab ntsha, thiab tsim kom muaj kev kuaj mob kom raug. Yog li, thaum kuaj, koj tuaj yeem:
- xyuas seb lub pulse nthwv dej puas hloov;
- kuaj ntshav qis hauv qee thaj chaw;
- pom tias ntshav ntws tsis sib xws;
- ceeb toom retrograde ntshav ntws thaum so lossis, hloov pauv, kev ntxhov siab;
- pom qhov hloov pauv ntawm pob taws-brachial Performance index: qhov no yog qhov ntsuas uas suav nrog qhov sib piv ntawm qhov siab ntawm tibial leeg hauv thaj tsam ntawm pob taws thiab cov hlab ntsha brachial;
- ceeb toom tias muaj cov kab mob tawm ntawm cov ntshav los ntawm cov hlab ntsha perforating;
- saib qhov poob thoob plaws tib lub hlab ntsha.
Ib qho lossis ntau yam kab mob ua rau tus kws kho mob tuaj yeem kuaj mob. Yog tias tsim nyog, tus kws kho mob tuaj yeem xa tus neeg mob mus kuaj ntxiv.
