Hypoplasia wa mtsempha wamagazi bwino vertebral: mbali matenda ndi mankhwala

Otchedwa "Chabwino vertebral mtsempha wamagazi hypoplasia" mu ntchito zachipatala amatanthauza yeniyeni chikhalidwe pathological yodziwika ndi underdevelopment chotengera, ndilo chifukwa cha yaikulu hemodynamics mu ubongo, makamaka kumbuyo kwa dipatimenti, yomwe anapanga kuchokera Circle wa Willis ziwiya beseni ake. Mwachibadwa, munthu anayamba awiri mitsempha vertebral, amene nthambi ku mtsempha wamagazi subclavian ndi kuwatsogolera ku njira chigaza enieni amakonda. mtima malo mbali mu msana khomo lachiberekero ndi kuti ali discontinuous mu njira yapadera kuti aumbike mwa pamaso mabowo mu vertebral njira yopingasa wa khomo lachiberekero vertebrae C7 C2. Pa mlingo wa chachiwiri khomo lachiberekero mitundu vertebral mtsempha wamagazi ndi kupopa (thupi kupinda) kuchepetsa magazi zimachitika yoweyula, komanso zimachitika kuthamanga asanalowe M'mimbamo cranial. Pankhaniyi, hypoplasia a mtsempha wamagazi ndi vertebral kaŵirikaŵiri ambiri anaona pa malo malo nthambi chotengera zazikulu kwa mphindi kupinda.

Akamanena za maganizo "hypoplasia wa mtsempha wamagazi bwino vertebral" ndi ndondomeko pathogenesis

Pansi hypoplasia anatanthauza hypoplasia chotengera amakhala ndi kuchepetsa kwambiri wa lumen pa malo ndimeyi ake mu ngalande fupa. kuchepetsa Izi kugwirizana ndi kuphwanya ziwalo khosi ndi ndime msana, zikubweretsa pang'onopang'ono kumanga mmwamba zizindikiro. Sangafanane amalephera kuzindikira yaikulu yoyendera sanali apadera, monga madandaulo kwambiri wodwalayo ali pa ululu m'dera khomo lachiberekero. Komabe, hypoplasia wa lamanja vertebral mtsempha wamagazi ayi zogwirizana ululu khomo lachiberekero, chifukwa pa mlingo sichipereka nthambi, kutanthauza kuti akuluakulu khosi sangathe kulandira ischemia chifukwa malamulo ake. Chifukwa cha chilango linayenera kudwala zofunika, kenako vertigo zizindikiro zikawoneka paokha.

Ndipotu, kwa matenda zosowa pathological kutsogoleredwa ndi mfundo za kufunika, kuyambira mapindikidwe wa khomo lachiberekero matenda vertebrae amatha kukhala mu Mabaibulo limodzi ndi iwiri. Chotero ndondomeko ndi anawonjezera nthawi ndi kumafunika yabwino kwambiri chifukwa mtima compensatory wa ziwiya labwinobwino magazi kuonjezera lumen awo. Kudwala ndi Ufumuyo mtengo wochepa chifukwa apadera dera chipangizo oziziritsa kufalitsidwa, kwathunthu alembedwera lonse mitsempha anastamozirovanii. Pankhaniyi, chabe madera zapambuyo pa tsinde ubongo ndi cerebellum amavutika pa amgwirizano vertebral mtsempha wamagazi hypoplasia.

Malipilo hypoplasia ntchito zokhudza thupi

Ngati pali hypoplasia akutali a mtsempha wamagazi bwino vertebral, zizindikiro monga angapo zizindikiro si zenizeni zimene zimachitika chifukwa cha matenda zinchito za kusowa magazi kumbuyo kwa ubongo. Ndipotu, ngati kumachitika, ndondomeko ndi bwino decompensated ndipo amafuna chithandizo opaleshoni. Komabe, mpaka pa nsonga iyi, bola ngati ubongo si akukumana akusowa magazi kuti kudwala monga hypoplastic mtsempha wamagazi bwino vertebral, chithandizo pazikhalanso wothandizila pharmacological yekha kuti kumapangitsanso zipangizo za wolumikizira bedi.

Hypoplasia wa mtsempha wamagazi bwino vertebral: matenda

Kubvomereza matenda ikuchitika pa kuona koyamba ndi matenda okhudza ubongo a. Iwo n'komwe madandaulo discoordination, kawirikawiri kukomoka, achipambano pa kuwuka. Iganizireni iwo, komanso mosavuta pamaso pa zipolowe mu dongosolo la khomo lachiberekero msana, ndi katswiriyu atume wodwala kwa ultrasound mosamala mitsempha vertebral. Pankhaniyi chiletso lumen kuposa 2 mm awiri (zambiri 3.6 - 3.8 mm) - bwino matenda umboni morphologically natsimikiza pamaso pa matenda. Lusoli idzachitika, ndi angiography yoyang'anira mosiyana.
