Intravascular ultrasound (IVUS) yog kev kuaj mob. Qhov kev ntsuas no siv cov suab sib luag los pom hauv cov hlab ntshav. Nws muaj txiaj ntsig zoo rau kev ntsuam xyuas cov hlab ntshav ntawm cov ntshav txhaws uas muab lub plawv.

Qhov quav me me quav wand yog txuas rau sab saum toj ntawm cov raj nyias nyias. Cov raj no yog hu ua catheter. Lub raj yas yuav muab ntxig rau ntawm txoj leeg ntawm koj cheeb tsam ua thaj chaw thiab txav mus rau hauv lub siab. Nws yog qhov txawv ntawm cov pa ob leeg ua ke ultrasound. Duplex ultrasound yog ua los ntawm sab nraud ntawm koj lub cev los ntawm qhov muab lub tshuab hloov pauv rau ntawm daim tawv nqaij.

Lub koos pis tawj ntsuas seb lub suab vuag cuam tshuam txog cov hlab ntshav li cas, thiab hloov lub suab nrov rau hauv cov duab. IVUS muab kev saib xyuas kev noj qab haus huv rau koj saib ntawm koj cov hlab ntshav tawm sab hauv-sab nraud.

IVUS yuav luag txhua lub sijhawm ua hauv kev txheej txheem. Vim li cas nws thiaj yuav ua muaj xws li:

  • Tau txais cov ntaub ntawv hais txog lub plawv lossis nws cov hlab ntsha lossis txhawm rau nrhiav yog tias koj xav tau phais lub plawv
  • Kho qee hom mob ntshav siab

Angiography muab kev saib dav dav rau txoj hlab ntshav txhaws. Txawm li cas los xij, nws tsis tuaj yeem qhia ntawm phab ntsa ntawm cov hlab ntsha. Cov duab IVUS qhia txog phab ntsa leeg thiab tuaj yeem qhia cov roj (cholesterol) thiab cov rog rog (cov quav hniav). Ua ntau ntxiv ntawm cov nyiaj no tuaj yeem ua rau koj muaj kev pheej hmoo rau lub plawv nres.


IVUS tau pab cov kws zov me nyuam kom to taub tias yuav ua li cas txhaws. Qhov no hu ua stent restenosis.

Ua rau IVUS ib txwm ua kom paub tseeb tias lub stent raug raug tso rau thaum lub sijhawm angioplasty. Nws tseem yuav ua tau los txiav txim siab seb qhov twg stent yuav tsum muab tso rau.

IVUS kuj tseem siv tau rau:

  • Saib ntawm aorta thiab cov qauv ntawm cov leeg phab ntsa, uas tuaj yeem pom cov quav hniav tsim
  • Nrhiav cov roj ntsha twg yog koom nrog hauv aortic dissection

Muaj qee qhov kev pheej hmoo me me rau cov teeb meem nrog mob angioplasty thiab mob catheterization. Txawm li cas los xij, kev ntsuam xyuas muaj kev nyab xeeb heev thaum ua los ntawm pawg neeg paub. IVUS ntxiv me ntsis kev pheej hmoo.

Kev phom sij ntawm cov tshuaj loog thiab phais feem ntau yog:

  • Kev tshuaj tiv thaiv
  • Cov teeb meem ua pa
  • Los ntshav, ntshav txhaws
  • Kab mob

Lwm cov kev pheej hmoo muaj xws li:

  • Kev puas tsuaj rau lub plawv dhia lossis txoj hlab ntshav
  • Plawv nres
  • Lub plawv dhia tsis xwm yeem (arrhythmia)
  • Raum tsis ua haujlwm (muaj kev pheej hmoo siab dua rau cov neeg uas twb muaj mob raum lossis ntshav qab zib)
  • Mob stroke (qhov no tsis tshua muaj)

Tom qab ntsuas, catheter tawm tag nrho. Daim ntaub qhwv tau muab tso rau ntawm thaj chaw. Koj yuav tau hais kom pw ncaj nraim ntawm koj sab nraub qaum nrog nias ntawm koj lub puab tais thaj tsam li ob peb teev tom qab kev tshuaj ntsuam kom tsis txhob los ntshav.


Yog tias IVUS tau ua thaum lub sijhawm:

  • Txoj Kev Ntsuas Plab Tes Mob: Koj yuav nyob hauv tsev kho mob ntev txog 3 rau 6 teev.
  • Angioplasty: Koj yuav nyob hauv tsev kho mob li 12 rau 24 teev.

Qhov IVUS tsis ntxiv rau lub sijhawm koj yuav tsum nyob hauv tsev khomob.
