An arteriovenous malformation (AVM) iboka remitsipa yeropa iyo inonyanya kuwirirana pamwe chete. AVM dzinogona kuitika mumuviri wose, uye uropi hweVVM hunogona kunyanya kukuvadza. Nemhaka yekugadzirisa kwavo, rimwe shoko rinowanzoshandiswa kutsanangura AVM "arteriovenous fistula."
Overview
AVM dzakagadzirwa nemariti uye mitsipa yakabatana kune imwe nzira nenzira isingawanzoitiki.
Ariti-ku-Vein Connections
Kune miviri miviri mikuru yemidziyo yeropa: arteri uye miviri. Mishonga inounza oksijeni-yakawanda neropa kubva pamwoyo kusvika kumativi ese emuviri. Sezvo mitsetse inopinda mukati memaviri, inosvika mumidzitiro yeropa ine simba, kusvikira yava duku uye yakaoma. Iyi nzvimbo yemidziyo midzi yeropa inozivikanwa semubhedha we capillary, uko okisijeni inowanikwa zvakananga kune imwe sero mumuviri. Makanda emapapiro akabatanidza pamwechete kuti aite mitsetse, uye inowedzera zvishoma apo ichibuda nhengo dziri munzira yavo kuenda kumwoyo nemapapu, apo ropa rinozadzwa ne oksijeni.
Tsvaga zvakawanda pamusoro pemidziyo yeropa inobatwa nechirwere pano .
Kuipa kweArteri-ku-Vein Connections
AVM dzehupombwe dzakagadzirwa nemariti uye mitsipa iyo yakabatanidzwa nenzira yakadai kuti hapana mubhedha we capillary zvachose. Izvi zvinokonzera kushungurudzwa kwemasayeri kuti aparidzirwe zvakananga mumaketani mukati meAVM.
Kuyerera kweropa kusina kujairika kunoumba nzvimbo yekumanikidzika yakanyanya uye kukwirira kwakanyanya kunokonzera kuti AVM ive yakakura kupfuura nguva, uye kuchinja basa rehuputi hwehupi dzakapoteredza.
Chakaita sei?
AVM dzeBongo dzinosiyana muhukuru. Zvimwe zviduku uye zvisingambogadziri matambudziko zvachose. Vamwe vanoita mikuru mikuru uye inotambudza yemasiteri iyo inotapisa zvakasimba sezvo ichibatanidza zvakananga kumasana eAVM.
AVM inogona kuwanikwa chero kupi muuropi, kusanganisira cerebral cortex, nyaya yakachena, uye brainstem.
Ndiani Anovandudza AVM Brain?
AVM yehupenzi inobata pamusoro pe1% yevanhu, uye iripo pakuberekwa, asi haigoni kuchinja vanopfuura imwe nhengo yemhuri imwechete. Zvinowanzoitika zvakaenzana kune varume nevakadzi.
Zviratidzo zvinogona kutanga panguva ipi neipi, asi hazvisi zvisizvo kuti vanhu vaongorwe mushure memakore makumi mashanu.
Zviratidzo
Mukana weAVM unogona kubuda kana kuputika, zvichikonzera zviratidzo zvakanyanya zvemaharachnoid hemorrhage . Inenge hafu yeAVM inokonzera zviratidzo zvavo zvekutanga nenzira iyi. Zviratidzo zveAVM dzakaputika zvinosanganisira kurwadziwa kwepakarepo, kwakakomba musoro, kusimba kwechimwe chikamu chechiso kana muviri, kugunun'una, kuvhiringidzika, kurasikirwa kweruzivo kana kurwadziwa kwepamusoro kunoramba kuripo.
Inenge hafu yevaya vane AVM zviratidzo zviratidzo kunyange kana AVM isingadi ropa. Zviratidzo izvi zvinogona kusanganisira kukanganisa , kuora musoro, uye kurwara zviratidzo zvakadai se hemiplegia kana hemiparesis.
Kuziva
Kazhinji, uropi hweC CT kana uropi hweMRI hunokosha kana chiremba wako achifunga kuti unogona kuva neAVM.
Apo kubuda ropa kwakaitika muuropi, AVM inogona kuva yakaoma kuziva nekuda kwekuvapo kweropa riri pedyo. Dzimwe mimwe miedzo, yakadai sechirebral angiogram, uropi MRA kana uropi CTA zvakananga kuongorora ropa mumudziyo muuropi, uye inogona kubatsira mukujekesa kujekesa AVM.
Kurapa
Mhando dzakasiyana-siyana dzehutano dzinowanikwa dzinosanganisira kubviswa kwekuvhiya, endovascular embolization, uye stereotactic radiosurgery - zvose zvingashandiswa pamwe chete kana kuti pamwe. Chinangwa chemishonga iyi ndechekuderedza njodzi yekubuda ropa, kana kubudazve ropa.
Nyaya iripo iye zvino pasi pekutsvakurudza kwakanyanya ndeyokuti vanachiremba vanofanira kubata maAVM anowanikwa vasati vatadzisa kubuda ropa. Ngozi yekubuda ropa inoremedzwa pangozi yekuvhiyiwa kune mumwe nomumwe-zvichienderana nezvinhu zvakadai sehutano hwakakwana uye kukwanisa kubvumira chirwere, nzvimbo, ukuru uye maitiro eAVM.
Prognosis
Kutaura kweAVM kunoenderana nezvimwe zvinhu, kutanga kana iAVM inowanikwa mushure mekunge kana kubuda ropa. Vanopfuura makumi mapfumbamwe kubva muzana veavo vakabuda ropa vakapona muitiko. Mune avo vane ma AVM vasati vabuda ropa, kufungidzira kwakabatana zvakananga nehukuru hweAVM, zviratidzo, pedyo nekukosha kwehuropi uye kana kwete iyo AVM inotapwa.
Shoko Rinobva
Iwe unogona kunge wakamboudzwa kuti iwe kana munhu waunoda ane AVM. Kana iwe wakanga uine uropi hwehupombwe hwakadai sekushaya simba nekuda kwekubuda ropa, iwe unogona kunge uchida kubatsiridzirwa apo iwe uchidzoka. Zvose, nekunyatsotevera kutevera uye kurapwa, kufara kwako kwakanaka. Pasinei nokuti AVM yako yakavhara kana kwete, urongwa hwako hwekurapa huchabatanidza pedyo nekutevera pamwe neboka rako rekuchengetedza hutano sezvaunoita iwe navanachiremba vako kuti kana kuti kwete kurapwa kwakakosha here.
