I-Hypoplasia ye-artébral yomnatha: izinto kunye neendlela zokonyango

Ngaphansi kwesihloko esithi "i-Hypoplasia ye-artébral artery" kwiyeza elisebenzayo lithetha isimo esithile sentsholongwane esichazwe ngokuphuhliswa kwesitya, esiphumo sithintela i-hemodynamics engqondweni, ngokukodwa kwimimandla engaphaya kwayo, apho isangqa sase-Wilysian senziwe kwiinqanawa zesitya sayo. Ngokuqhelekileyo, umntu uye wakhula imithambo emibini ye- vertebral ephuma kwi- subclavia kwaye ithunyelwa kwikrele ngendlela ethile. Ubunqwenelekayo beempahla kwiindawo zomlomo wesibeleko kukuba bayadlula kwisiteshi esikhethekileyo esithintekayo, esakhiwe ngenxa yobuninzi bezinto ezivulekileyo kwiinkqubo ezithintekayo ze-vertebrae yeCervical C7-C2. Kwinqanaba le-vertebra yesibini yomlomo wesibeleko, i-artery yenza i-siphon (ibhondi yomzimba) ukunciphisa umtsalane we-pulse kunye ne-pulse yexinzelelo lobungozi ngaphambi kokungena kwisigxina se-cranial. Kule meko, i-hypoplasia ye-artébral artery idlalwa rhoqo kwisiza esivela kwisayithi yesebe ukusuka kwisikhulu esikhulu ukuya kweso sithuba sokuguqa.

Ingundoqo yegama elithi "hypoplasia ye-artébral artery" kunye ne-pathogenesis yenkqubo

Ngaphansi kwe-hypoplasia kuthathelwe ukuphuhliswa kwesitya, esichazwe ngokukhawulelana okukhulu kwelo lumen kwindawo yokuhamba kwimizila yesithambo. Oku kuncipha, okubandakanya ukuphulwa kwentuthuko yentamo kunye nomgudu, kubangela ukwanda kweempawu. Ngokuqhelekileyo kunokwenzeka ukuyiqonda ekubhapheni kokuqala okungaqhelekanga, njengoko izikhalazo zesigulane malunga nokukhathazeka kwinqanaba lebeletshi libizwa ngakumbi. Nangona kunjalo, i-hypoplasia ye-artébral umzobo ongenanto ayixhunyiwe naluphi na indlela nge-syndrome yeentlungu zesifo somlomo, kuba eli nqanaba aligodli amagatsha, oko kuthetha ukuba izitho zentamo azikwazi ukufumana ischemia ngenxa yokunciphisa. Ngako oko, i-pathology ephambili ihlaziywa, emva koko iimpawu zesimo sezulu zihamba ngokuzimela.

Enyanisweni, ukuba ukuxilongwa kukukhokelwa yimimiselo yokufaneleka kwemfuyo, ekubeni ukukhubazeka kwe-vertebrae yomlomo wesibeleko, lesi sifo sinethuba lokuphuhliswa kwizinto ezihlukeneyo kunye nangamacala amabini. Inkqubo enjalo ilwelwa ngexesha kwaye iqhubela phambili kakhulu ngenxa yokunyusa ukuhlawulelwa kwegazi ngeenqanawa ezihambelanayo kunye nokwanda kwe-lumen yabo. I-pathology ayinikezwa lukhulu kwaye ngenxa yeso sixhobo esikhethekileyo se-circulatory system yengqondo, eyakhelwe ngokupheleleyo kwi-anastomosing enkulu yeemitha. Kule meko, kuphela iindawo ezingasemva, ubuchopho buba kunye ne-cerebellum inokubandezeleka nge-hypoplasia yamazwe angama-40.

Ukuhlawulelwa kwe-hypoplasia ngamakhono omzimba womzimba

Ukuba kukho i-hypoplasia ekhethiweyo ye-artébral umzobo, i-symptomatology iqulethe impawu ezingezizo ezibangelwa ukuphazamiseka kokusebenza kwegazi kwiindawo ezisemva kweengqondo. Enyanisweni, ukuba ibonakalisa, le nkqubo ichithwe ngokucacileyo kwaye idinga unyango. Nangona kunjalo, kude kube lo mzuzwana, ngelixa ingqondo engabonakali kwintlupheko yentsholongwane, unyango olufana ne-hypoplasia ye-artébral umthamo ofanelekileyo, unyango lumele lubandakanye kuphela i-agents e-pharmacological ehlenga imithwalo yegazi yesibhedlele.

I-Hypoplasia ye-arterial artery: i-diagnostic

Ukuqwalaselwa kwesi sifo kuqhutyelwa kuviwo oluphambili nge-neurologist. Ziyakuqwalasela izikhalazo malunga nokuthotywa, ukungabonakalisi okungafanekiyo, ukuphazamiseka xa uvuka. Ukuvavanya, kunye nokubonakala kokuphula umthetho kwisigodlo somlomo wesibeletho , i- neurologist inelungelo lokuthumela isigulane kwi-ultrasound uvavanyo lweetriyiti ze-vertebral. Ngexesha elifanayo, ukucuthwa kwe-lumen ukuya kwi-2 mm ububanzi (kwimiqathango ye-3,6 - 3,8 mm) ngumqondiso ocacileyo wokuxilonga, ngokuqinisekileyo ngokuqinisekileyo ukuqinisekiswa kwesi sifo. I-Angiography inokuthi yenziwe kunye nokuqaliswa kohluke.
