Qhov sib txawv tseem ceeb ntawm qhov tseeb thiab qhov tsis tseeb yog qhov tseeb ntawm qhov aneurysm yog qhov loj ntawm tag nrho peb txheej ntawm phab ntsa ntawm cov hlab ntsha thaum qhov tsis tseeb aneurysm lossis pseudoaneurysm tsis yog qhov loj ntawm txhua txheej ntawm cov hlab ntsha phab ntsa.
Aneurysm yog bulging ntawm phab ntsa ntawm cov hlab ntsha, uas ua rau tsim cov pob txha los yog zais pa. Nws tshwm sim vim qhov tsis muaj zog ntawm cov hlab ntsha phab ntsa. Feem ntau, aneurysms muaj nyob rau hauv cov hlab ntsha dua li cov hlab ntsha. Thaum lub aneurysm nce nyob rau hauv qhov loj, qhov tshwm sim ntawm rupturing cov hlab ntsha nce. Yog tias cov hlab ntsha tawg, nws ua rau cov ntshav tsis tswj tau. Aneurysm txawv ntawm morphology, ua rau thiab qhov chaw. Muaj ob hom aneurysms. Lawv muaj tseeb thiab cuav aneurysm. Qhov tseeb aneurysm cuam tshuam tag nrho peb txheej ntawm phab ntsa ntawm cov hlab ntsha, tab sis, qhov tsis tseeb aneurysm tsis yog qhov loj ntawm ib txheej ntawm phab ntsa hlab ntsha.
Dab tsi yog Aneurysm?
Tseeb aneurysm yog bulging lossis loj ntawm tag nrho peb txheej ntawm phab ntsa ntawm cov hlab ntsha. Nws yog ib qho txawv txav ntawm cov hlab ntsha vim yog phab ntsa hlab ntsha tsis muaj zog. Qhov tseeb aneurysm feem ntau yog qhov tshwm sim ntawm atherosclerosis. Nws kuj tuaj yeem tshwm sim los ntawm kev kub siab, vasculitis, congenital, myocardial infarction thiab syphilis, thiab lwm yam. Feem ntau, qhov tseeb aneurysms yog fusiform lossis saccular hauv cov duab. Fusiform-shaped aneurysm bulges los yog balloons tawm ntawm txhua sab ntawm cov hlab ntsha. Lub saccular-shaped aneurysm bulges lossis balloons tawm ntawm ib sab xwb.

Dab tsi yog False Aneurysm?
False aneurysm yog ib qho kev sau ntawm cov ntshav tawm ntawm cov hlab ntsha. Nws yog cov kab noj ntshav uas muaj cov hlab ntsha nruab nrab ntawm cov hlab ntsha thiab cov ntaub so ntswg ib puag ncig. Nws tsis yog qhov loj ntawm ib txheej ntawm phab ntsa ntawm cov hlab ntsha. Yog li ntawd, nws yog ib tug sab nraud hematoma. Qhov tsis tseeb aneurysm no tuaj yeem txhaws lossis tawg tawm ntawm cov ntaub so ntswg. False aneurysm yog tshwm sim los ntawm kev raug mob los yog iatrogenic. Nws kuj tuaj yeem yog vim qhov kev txiav tawm tsis tu ncua, fibromuscular dysplasia, mycotic aneurysm, hlab ntsha raug mob, thiab lwm yam.
Daim duab 02: False Aneurysm
Qhov kev pheej hmoo ntawm kev tawg ntawm qhov tsis tseeb yog qhov siab dua qhov tseeb ntawm qhov quav. Qhov no yog vim qhov tsis tseeb aneurysm muaj kev txhawb nqa tsis zoo los ntawm phab ntsa aneurysm. Yog li ntawd, qhov cuav aneurysm yuav tsum tau kho. Kev phais yog ib qho kev kho mob, thaum muaj ob peb txoj kev kho mob tsawg dua.
Dab tsi zoo sib xws ntawm qhov tseeb thiab qhov tsis tseeb?
- Qhov tseeb thiab qhov tsis tseeb yog ob hom aneurysms.
- ob leeg ua rau cov hlab ntsha tawg.
- Thaum qhov loj ntawm aneurysm nce, qhov kev pheej hmoo rupturing nws kuj nce.
- Ob qhov tseeb thiab tsis tseeb aneurysms tuaj yeem yog qhov teeb meem ntawm myocardial infarction.
Qhov txawv ntawm qhov tseeb thiab qhov tsis tseeb yog dab tsi?
True aneurysm yog ib qho txawv txav ntawm cov hlab ntsha uas muaj tag nrho peb txheej ntawm phab ntsa hlab ntsha. Nyob rau hauv sib piv, cuav aneurysm yog ib tug sau ntawm cov ntshav tawm sab nraum cov txheej txheem ntawm cov hlab ntsha. Qhov tseeb aneurysm cuam tshuam tag nrho cov txheej txheem ntawm cov hlab ntsha phab ntsa thaum qhov tsis tseeb aneurysm tsis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm qhov tseeb thiab tsis tseeb aneurysm. Ntxiv mus, qhov kev pheej hmoo ntawm rupture yog siab dua nyob rau hauv tsis tseeb aneurysm tshaj ib tug tseeb aneurysm.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm qhov tseeb thiab qhov tsis tseeb.
Summary – True vs False Aneurysm
Aneurysm yog ib qho o ntawm cov hlab ntsha. Nws ua rau qhov txawv txav los yog zais pa hauv cov hlab ntsha piv rau qhov loj me. Qhov tseeb thiab cuav aneurysms yog ob hom. Lub phab ntsa ntawm qhov tseeb aneurysm tswj cov txheej txheem peb-txheej ntawm cov hlab ntsha (intima, media, adventitia), thaum lub qhov txhab tsis tseeb tsis koom nrog peb txheej ntawm phab ntsa hlab ntsha. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm qhov tseeb thiab tsis tseeb aneurysm. Ntxiv mus, atherosclerosis yog qhov feem ntau aetiology ntawm qhov tseeb aneurysm thaum kev raug mob yog qhov feem ntau aetiology ntawm qhov tsis tseeb aneurysm.
