Nyhuv ntawm atrophic hydrocephalus nyob rau hauv lub subarachnoid qhov chaw

Hydrocephalus nyob rau hauv kev kho mob xyaum yog yus li ib tug edema nyob rau hauv lub hlwb. Qhov no raws li txoj cai qhia ib tug ntau txuam nrog nyob rau hauv lub cranial txha caj kua.

Feem ntau, muaj yog ib qhov kev ntawm hlwb txha nqaj qaum kua. Cov tshuaj yeeb dej caw nyob rau hauv cov leeg nrob qaum thiab lub hlwb ntxuav rau tag nrho cov sab ntawm ib tug tsis muaj kob pob tshab kua, uas muaj ntau zog, Hmoob cov uas yog kev tiv thaiv thiab pab pub mis. Sab nraum lub ncig ntawm hlwb txha nqaj qaum kua nyob rau hauv lub hlwb yuav siv sij hawm qhov chaw ntawm vascular thiab mos plhaub tshaj tag nrho saum npoo ntawm lub cerebral hemispheres thiab lub cerebellum. Qhov no nto yog hu ua tus subarachnoid qhov chaw. Lub hauv paus nyob rau hauv lub cranial hlwb situated ib tug ob peb qhov chaw ntawm cov kua txuam nrog. Lawv yog cov hu ua cisterns. Cov seem sib thooj, nyob rau hauv txawv kev qhia, txoj kev ua cawv subarachnoid qhov chaw ntawm lub paj hlwb thiab kev cob cog rua rau tib lub nto nyob rau hauv cov leeg nrob qaum.

Cov yav tas yuav tsis muaj ib tug system ntawm canals thiab kev tiv thaiv meshes trophic system. Subarachnoid qhov chaw ntawm cov leeg nrob qaum dorsal paus muaj ib tug tuab ncej muaj fibrotic fibers intertwined. Nws yuav tsum tau muab sau tseg hais tias muaj no xwb plexus. Lateral subarachnoid qhov chaw ntawm lub toothed formations ligament thiab dorsal paus muaj. Pem hauv ntej ntawm mos mos thiab arachnoid collagen beams txheej txheem tsis tsim obstacles rau lub ncig ntawm hlwb txha nqaj qaum kua.

Atrophic hydrocephalus raug mob yog khiav passive txheej txheem tshuaj hlwb hloov, zuj zus lawm nyob rau hauv volume, lub hlwb txha nqaj qaum kua. Tus mob yog yus nyob rau tib lub sij hawm thiab feem ntau symmetrical ventricular o. Nyob rau hauv cov ntaub ntawv no, lub basal cisterns thiab subarachnoid chaw convexital txhab nyob rau tom qab ntawm tsis muaj periventricular edema.

Lub hauv paus atrophic hydrocephalus atrophic txheej txheem yog diffuse cim. Demyelination tshwm sim los ntawm thawj kev puas tsuaj rau lub paj hlwb, ua rau ib tug txo ob grey thiab dawb teeb meem.

Tus thawj ces atrophic hydrocephalus yuav pom tawm tom qab ob los yog plaub lub lis piam tom qab TBI (puas hlwb raug mob). Nyob rau hauv cov nram no sau ntawv, los yog long-term kev vam meej ntawm tus txheej txheem, los yog nws tsis.

Kws txawj cais me me, loj tsawv lossis mob hauv daim ntawv ntawm tus kab mob no.

Nyob rau hauv thawj rooj plaub uas nws qhia ntsis cerebral Atrophy, nyob rau hauv uas yog qhia ib tug me ntsis expansion nyob rau hauv lub subarachnoid grooves thiab slits - ib tug los yog ob tug millimeters, thiab nyob rau hauv lub ventricular system.

Qhov nruab nrab degree ntawm tus kab mob yog yus muaj los ntawm ib tug tseem ceeb kev hloov - extension mus rau hauv lub subarachnoid fissures thiab tej kab nrib pleb nyob rau hauv lub peb mus rau plaub millimeters. Nyob rau hauv tas li ntawd, cov tseem txuas rau cov kev ceev yuav txo tau nyob rau hauv lub hlwb cov ntaub so ntswg ntawm ntsis xwm.

Loj kab mob no yog txawv nyob rau hauv ib tug tseem ceeb expansion ntawm lub ventricular system (ZVI ntau tshaj 20.0), nyob rau hauv lub subarachnoid fissures thiab tej kab nrib pleb - ntau tshaj plaub millimeters. Ntxiv mus, muaj ib tug generalized txo nyob rau hauv lub ceev nyob rau hauv lub hlwb cov ntaub so ntswg.

Nws yuav tsum tau muab sau tseg tias heev ntawm morphological thiab soj ntsuam ces ntawm atrophic hydrocephalus tsis thaum uas tig.

Yog mob yog nqa tawm nrog rau kev siv CT thiab MRI. Tib mus thiab symmetrical expansion ntawm lub subarachnoid qhov chaw nyob rau hauv nrog ib qho kev nce nyob rau hauv lub cerebral ventricles, tsis muaj periventricular edema, tsis muaj tsis ntseeg, hais lus nyob rau hauv dej siab ntawm cov atrophic hydrocephalus.

Nyob rau hauv thaum ntxov ua sawv ntawm tus kab mob yog feem ntau tsis tau ua kom muaj txaus thiab ruaj khov nyiaj ntawm tus neeg mob tus mob. Txawm li cas los, nyob rau theem ntawm cov kab mob, nyob deb-advanced, lub raug yog heev unfavorable.
