A lumbar puncture (LP), tseem hu ua tus txha caj qaum, yog ib qho kev tawm tsam sab nraud uas siv los tshem tawm cov qauv ntawm cov kua cerebrospinal (CSF) los ntawm qhov chaw subarachnoid hauv qaum (Qhov kev sim no zoo ib yam li kev kuaj ntshav, uas ib rab koob tau muab tso rau hauv cov hlab ntsha txhawm rau txhawm rau txhawm rau kuaj ntshav.)
CSF coj los ntawm tus txha caj qaum qhov twg?
CSF feem ntau tau txais los ntawm kev sib tsoo lub lumbar (tus txha caj qaum). Thaum lub sij hawm tus txheej txheem, ib rab koob yog ntxig feem ntau nruab nrab ntawm qhov thib peb thiab thib plaub lumbar vertebrae thiab cov kua CSF tau sau rau kev sim.
CSF tau nyob qhov twg hauv lub lumbar puncture?

CSF tuaj qhov twg?
Feem ntau CSF yog tsim nyob rau hauv lub paj hlwb ventricles. Cov chaw muaj peev xwm ntawm keeb kwm suav nrog choroid plexus, ependyma, thiab parenchyma[2]. Anatomically, choroid plexus cov ntaub so ntswg yog floating nyob rau hauv lub cerebrospinal kua ntawm lub lateral, thib peb, thiab plaub ventricles.
CSF tau mus rau tus txha caj qaum li cas?
Los ntawm qhov thib peb ventricle, nws ntws mus rau lwm qhov ntev txoj kev hu ua lub aqueduct ntawm Sylvius mus rau hauv lub ventricle plaub. Los ntawm qhov thib plaub ventricle, nws hla dhau ntawm peb qhov qhib me me hu ua foramina thiab mus rau qhov chaw subarachnoid nyob ib puag ncig lub hlwb thiab qaum qaum.
