N'chifukwa chiyani kukhala ndi sitiroko ischemic

Mu fibrillation matenda, ndi infarction m'mnyewa wamtima, ndi apulasitiki mavavu mtima, endocarditis opatsirana chikhalidwe embolus kuchokera amene atseka chotengera lumen ndipo kumayambitsa ischemic ubongo minofu. Pamene yaing'ono chotengera occlusion mu infarction m'mnyewa wamtima, shuga, ndi othamanga magazi ungadzakhazikitsidwe wa gawo recessed wa necrosis mu ubongo. Choncho kupanga madera kwambiri kuwonongeka ischemic wa hemispheres ubongo ndi m'mimba pang'ono, ndipo akutchedwa lacunar sitiroko. Nthawi zambiri zizindikiro za mawonekedwe matenda zidzachotsedwa.

Izi ndi matenda aakulu - Ischemic sitiroko, zifukwa izi mwachidule motere:

• The thrombus kapena zolengeza-ku khoma ndi mwa mwazi umalowa ziwiya ka ubongo.
• Magazi aumirira akuswa kutali endocardial ndi atseka wa lumen wa mtsempha wamagazi ubongo.
• Ngati kuphwanya hemodynamics, kulephera mtima ndipo makope osauka ndi embolus pa mtima kugwa mu mtsempha wamagazi carotid.
• Lacunar oziziritsa ischemia pa maziko a matenda oopsa ndi shuga kwambiri.
• Zimachitika pa zoopsa mitsempha mwina mtolo, imbaenda ischemia ubongo.

Ischemic sitiroko ali madigiri atatu a mwamphamvu. Kuonetsetsa zizindikiro oziziritsa ndi focal. Mutu, kupweteka eyeballs, amene kumawonjezera ndi kayendedwe kawo, nseru, chizungulire komanso kusanza ndi zizindikiro zofanana.

Zotsatira zake zimadalira m'badwo wodwala, malo kutanthauzira kwa occlusion mtima, nthawi ya occlusion wa collaterals ndi magazi. Nthawi zambiri zadutsa kuyambira blockage ndi malo aakulu kugonja, mofulumira kubwera njira sizingasinthe. Zizindikiro za sitiroko ischemic zimadalira kutanthauzira kwa occlusion lapansi. Pamene occlusion wa mtsempha wamagazi zapambuyo oziziritsa amakhudza miyendo m'munsi, kukhala aakulu kufooka, paresis kapena ziwalo, kulankhula mkhutu.

Ndi kugonjetsedwa kwa mtsempha wamagazi zapambuyo oziziritsa pali kuphwanya mwa ntchito cerebellum pa tsinde ubongo, occipital ndi lobes mwakanthawi. Pali vuto kumeza maganizo kupuma, ndi kuswa za mtima. Kungakhale kutanganidwa kugwirizana kayendedwe, kudziwa ululu ndi kutentha. Chidwi stupor chikugwirabe kwa chikomokere, skewing nkhope chifukwa cha kugonjetsedwa kwa trigeminal ndi nkhope mitsempha ziwalo za theka thupi. Pa mbali ya osauka nystagmus, strabismus.

Ischemic sitiroko ndi occlusion wa mtsempha wamagazi pakati oziziritsa amakhala ndi chisokonezo kwenikweni ndi ziwalo mbali ina ya chotupa cha. Posasangalala tilinazo, akufotokozera paresis maganizo, nthambi kumtunda ndi nkhope.

Pamene carotid mtsempha wamagazi thromboembolism akufotokozera paresis mbali ina ndi madontho yokhudza ufiti masomphenya kumbali ya occlusion lapansi.

Pamene basilar mtsempha wamagazi occlusion Ischemic sitiroko uoneke m'njira zosiyanasiyana, malingana ndi kuchuluka kwa chotupa cha. Mwina tinnitus ndi kumva imfa ndi imfa yake, nystagmus ndi chizungulire, kusanza ndi nseru. Ndi kugonjetsedwa mu thunthu Malo basilar mtsempha wamagazi kapena vertebral mitsempha zingaoneke ziwalo wathunthu, wachiphamaso amaganiza paresis maso ndi chikomokere.

Ndondomeko ischemia ubongo minofu ndi kusintha mkati maola 6-12. Nthawi zina, pamene inu mukhoza kuwerenga pa tsiku. Choncho, n'kofunika bwino ndipo m'nthawi yake kupereka chisamaliro zofunika mankhwala kwa wodwalayo, ngati panali sitiroko ischemic. Kumupatsa mtendere, kukhazika mtima ndi mapapo, amathera kupewa mavuto. Nkofunika kuti abwezeretse magazi, chitetezo ubongo zisaonongeke zina, ndiponso thandizo la chakudya chake bwinobwino.
