Ib yam nkaus, dab tsi ua rau arachnoid granulations? Arachnoid granulation yog cov qauv uas muaj cov kua dej cerebrospinal (CSF) uas txuas mus rau hauv cov venous sinuses los ntawm kev qhib hauv dura mater thiab tso cai rau cov kua dej ntawm CSF los ntawm subarachnoid qhov chaw mus rau hauv cov hlab ntsha. Feem ntau lawv yog asymptomatic tab sis tuaj yeem ua tus tsos mob thaum loj txaus rau ua qhov ntswg occlusion.
Qhov thib ob, arachnoid granulations yog dab tsi?
Arachnoid granulation , tseem hu ua Pacchionian granulation , yog kev kwv yees ntawm arachnoid membrane (villi) rau hauv cov hlab ntsha uas tso cai rau CSF hla ntawm qhov chaw subarachnoid mus rau hauv cov hlab ntshav.
Qhov twg pom arachnoid granules?
Arachnoid granulation (AGs) yog tufts ntawm arachnoid membrane invaginated mus rau hauv lub dural sinuses los ntawm uas cerebrospinal kua (CSF) nkag mus rau hauv lub venous system. Cov kab mob yog feem ntau nyob nyob rau hauv cheeb tsam parasagittal raws lub superior sagittal sinus [1], uas yog qee zaus pom ntawm lub qhov txhab transverse.
