Carotid leeg dissection yog xav ntau dua ua los ntawm kev raug mob hnyav rau lub taub hau thiab/lossis caj dab. Kwv yees li ntawm 0.67% ntawm cov neeg mob tau mus rau hauv tsev kho mob tom qab kev sib tsoo tsheb loj tau pom tias muaj qhov tsis zoo. cov carotid kev raug mob, suav nrog kev phais mob, pseudoaneurysms, thromboses, lossis fistulas.
Tsis tas li kom paub yog, cov carotid artery tsim kua muag li cas?
A kev txiav txim yog a tsim kua muag ntawm txheej sab hauv ntawm phab ntsa ntawm ib qho cov leeg . Cov tsim kua muag cia cov ntshav nkag mus rau hauv nruab nrab ntawm cov khaubncaws sab nraud povtseg ntawm phab ntsa thiab cais lawv. Qhov no ua rau cov leeg phab ntsa kom tawg. Lub pob ua tau qeeb lossis nres cov ntshav ntws los ntawm qhov cov leeg.
Ib qho ntxiv, puas tuaj yeem tshem tawm cov hlab ntsha carotid kho nws tus kheej? Hauv a phais , sab hauv sab hauv ntawm cov hlab ntshav los kua muag, tsim qhov nrov plig plawg uas cov ntshav khov ua tau tsim nyob rau hauv lub nkoj. Qhov xwm zoo yog tias nyob hauv ntau qhov ntawm carotid phais , cov cov hlab ntsha yuav thaum kawg kho nws tus kheej thiab rov qhib dua thiab qhov pheej hmoo ntawm rov ua dua phais nyob rau hauv ib tug neeg mob tsawg heev.
Hauv qhov no, dab tsi tuaj yeem ua rau kua muag hauv cov leeg ntshav?
SCAD is a tsim kua muag hauv ib cov leeg uas nqa ntshav mus rau lub plawv. Thaum lub puab txheej ntawm lub cov leeg cais los ntawm cov txheej txheem txheej, cov ntshav ua tau pas dej ua ke nyob rau thaj tsam ntawm cov txheej. Qhov siab ntawm cov ntshav ua ke ua tau ib luv tsim kua muag ntev dua. Ntshav nyob nruab nrab ntawm cov txheej ua tau tsim cov ntshav txhaws (hematoma).
Nws yuav siv sij hawm ntev npaum li cas carotid artery dissection los kho?
Thaum kuaj pom thiab kho, cov neeg mob uas muaj carotid artery dissection yuav tsum tau ua raws li kev soj ntsuam thiab kev soj ntsuam ntawm ob leeg carotid hlab ntsha. Kev kho mob feem ntau yuav siv sij hawm 3-6 hli , thiab qhov xwm txheej ntawm kev sib cais sab nraub qaum yog siab dua hauv cov neeg mob no ntau dua li cov pej xeem.

Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
Dab tsi yog peb hom hlab ntsha hauv cov hlab ntsha?
Muaj peb yam tseem ceeb ntawm cov hlab ntsha: cov hlab ntsha. Lawv nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau tag nrho lub cev cov ntaub so ntswg. Capillaries. Cov no yog cov hlab ntshav me me, uas txuas cov hlab ntsha thiab cov leeg. Cov leeg
