Ukushaya isifo kungathinta noma iyiphi indawo ebuchosheni. I-brainstem stroke ngokuvamile isayizi encane kodwa ingabangela izimpawu ezinkulu.
I-brainstem ingumkhakha wengqondo osebenza ngokomzimba futhi esebenzayo ukuxhumana nomsebenzi ophezulu wobuchopho nomzimba wonke. Kubuye kube isikhungo sokulawula imisebenzi eminingana yokusekela impilo, njengomthetho wokuphefumula nenhliziyo.
I-brainstem, njengoba iboniswe esithombeni esingenhla, itholakala ekujuleni kobuchopho iphinde ibuyele emuva ngemuva kwekhanda, khona lapho i-skull ne-spine meet.
Ukuphazamiseka kwengqondo kubangelwa ukuphazamiseka kokugeleza kwegazi ngaphakathi kwemithambo emincane engemuva kwentamo nobuchopho, njengomshini we-basilar, umshini we-cerebellar ongakwesokudla noma wesobunxele ophansi ngemuva noma umthambo we-vertebral kwesokudla noma kwesobunxele. Izimbangela ze-brainstem stroke zifana nezimbangela zemivimbo kwezinye izingxenye zobuchopho.
Izimpawu
I-brainstem isifo singabangela izinkomba eziningi. Kungabangela ubuthakathaka noma ukulahlekelwa izinzwa eceleni komzimba okuphambene nohlangothi olonakalisiwe lwe-brainstem. Kungabangela umbono ophindwe kabili ngoba ukulawula ukunyakaza kweso kutholakala ku-brainstem. Uma ilanga elilodwa lingakwazi ukuhamba kanye nelinye iso elivamile-ukungabi nokunyakaza okulinganayo kuveza umbono wezithombe ezimbili. I-brainstem isifo esivame ukuhambisana nabafundi abangalingani .
Ukuzivocavoca noma ukuzwa kwemizwa kuvamile ukushaya isifo sobuchopho ngoba umqondo wokulinganisela ugcinwa ku-brainstem. Amandla omzimba angasenakulinganiswa nesimo somzimba angabangela enye yezinkophezelo ukuba iqhube noma uhlangothi olulodwa lomlomo sag . Kungabangela inkathazo yokugwinya , inkulumo ehlanjululwe noma ingenza ulimi lukhombe ohlangothini olulodwa.
Kungabangela ubuthakathaka bamahlombe, ngokuvamile kubonakaliswe njengokungakwazi ukuhlukumeza amahlombe ngendlela efanele.
Esinye sezici ezihlukanisa ubuchopho be-brainstem kusuka kwesifo sohlangothi lwe-cerebral cortex yiyona ethinta ukuzwa kwesobuso. Uma isifo sochungechunge lwe-brainstream senza iphutha lokubona ubuso, ubuso bunzima kunhlangothi eyodwa njenge-stroke. Lokhu kuqhathaniswa nokushaywa kwe-cortex ye-cerebral, okubangela ukuphutha komzwelo ohlangothini oluhlukile lobuso. Lokhu kungenye yezinkomba isazi sezinzwa esisebenzisayo ukuxilonga isifo sobuchopho.
Kwezinye izimo, ukushaywa kwesifo sengqondo kungabangela ama-hiccups.
Kungabangela ukulahlekelwa kwengqondo ngenxa yendima ye-brainstem ekulawulweni komsebenzi wokuphefumula nenhliziyo.
I-Brainstem Stroke Syndromes
Amanye ama-brainstrost stroke syndromes afaka iqoqo lezimpawu ezibonakala zingabambisene ezivela ndawonye ngoba ukulawula kwabo kusezindaweni ezincane ezigxilile ze-brainstem ezabelana ngegazi elifanayo.
Isiqalekiso sika-Ondine - sithinta ukuphefumula ngokuzithandela ngenxa yesilonda se-medulla engezansi
I-Webers syndrome-yi-stroke ye-midbrain ebangela ubuthakathaka behlangothini oluhlukile lomzimba kuhlangene nobuthakathaka bejwabu leso kanye nobuthakathaka bokuhamba kwamehlo ohlangothini olufanayo
Kuvaliwe ku-syndrome -kuyisifo esithinta ama-pons kanye nemiphumela ekuphelelweni okuphelele kanye nokungakwazi ukukhuluma, ngokuqonda okuqinile nokukwazi ukuhambisa amehlo. Kungabangela uketshezi olungavamile nokulingana kwamanzi .
I-Wallenberg syndrome, ebizwa nangokuthi i-lateral medullary syndrome -characteristically causessensory deficit ebusweni ohlangothini olufanayo njengokuhlukumeza nokuhluleka komzimba ohlangothini oluhlukile lwesifo, njengalesi sibonelo.
Ukuxilongwa
Ukuhlonza ukushaywa komzimba kudingekile ukuqonda okuningiliziwe kanye nesipiliyoni ngesifo sezinzwa. Ukushaywa kwe-Brainstem ngokuvamile akubonakali ebuchosheni be-CT noma ebuchosheni be-MRI njengemivimbo kwezinye izindawo zobuchopho.
I-brainstem iyingcosana futhi ivame ukubonakala ngeso lengqondo ngenxa yethambo eliseduze le-skull nengxenye engenhla yomgogodla. Ngokuvamile i-brainstem stroke ibonisa ukutholakala kwemitholampilo efihlekile okuhloswe ngokuhlolwa okusemtholampilo futhi kungathatha izinsuku ukuya emavikini ukuze izinguquko zivele ezifundweni ze-imaging - zihambisana nokuhlolwa kwemitholampilo.
Isibikezelo
Njengemivimbo kwezinye izingxenye zobuchopho, ukuhlushwa kwesifo sobuchopho buhlukahluka. Izimpawu zesifo sofuba ngokuvamile zifinyelela ukuqina okukhulu emahoreni nasezinsukwini ngokushesha ngemva kokuqala kokushaywa ngaphambi kokuqala ukuphulukisa . Ukuqapha nokwelashwa ngokucophelela kungasiza ekwandiseni ukutakula nokunciphisa ukukhubazeka emva kokushaywa ngechungechunge lobuchopho.
