Reversible Cerebral Vasoconstriction Syndrome uye Stroke
Kudzorerwa kwechiremba vasoconstriction syndrome (RCVS) inoratidzwa nezvinhu zviviri zvinokosha. Chokutanga ndechokutanga kamwe-kamwe kwekutinhira kwemusoro . Chechipiri ndechokuvapo kwezvinhu zvekuchepeta kana "vasoconstriction" apo rusvingo rwemumwe kana mishonga yakawanda muuropi inosangana nechigunzva chinodzivirira ropa kuderera. Iyi nharaunda inogona kuwanika nyore nyore ne catheter angiogram , kunyange dzimwe nguva inogona kuonekwawo nemagnetic resonance angiography (MRA) .
Kudzorerwa kwechiremba vasoconstriction inogona kana kuti isingatungamirire kurwisa . Muzviitiko zvakawanda, kurohwa zviratidzo zvinowanzoitika asi zvakadzoserwa zvachose gare gare. Zvisinei, vamwe vanhu vangave vakasara vane zvikwereti zvisingagumi. Chiitiko chacho chinogona kukonzera kukanganisa uye rufu.
Chii chinonzi Stroke?
Stroke chirwere chinokanganisa arteri inotungamirira uye mukati meuropi. Iko Nha. 5 chikonzero chekufa uye chinokonzera chikonzero chekuremara muUnited States. Kurwadza kunoitika apo ropa rinotakura oksijeni nemuviri kuuropi rinogona kudzivirirwa nejira kana kuputika (kana kuputsika). Kana izvozvo zvichiitika, chikamu cheuropi hachikwanise kuwana ropa (uye oxygen) inoda, saka iyo uye masero europi anofa.
Kushungurudza kunogona kukonzerwa kana nevhavha inodzivisa kuputika kweropa kuuropi (inonzi ischemic stroke ) kana neropa rekuchenesa uye kudzivirira ropa richiyerera kuuropi (inonzi chirwere chepfungwa ). A TIA (kushandiswa kwechikafu chinonzi ischemic), kana "shamhu shomanana", inokonzerwa nevhavha yenguva pfupi.
RCVS inogona kuita kuti ischemic kana kuti zvirwere zvinopisa, zvinowanzoita sechrachnoid hemorrhage .
Njodzi Zviitiko zveStroke
- Zera - Mukana wekushaya chirwere chakakanganwa kaviri kune imwe neimwe yemakore ehupenyu mushure memakore makumi mashanu nemashanu. Kunyange zvazvo chirwere chiripo kazhinji kune vakwegura, vanhu vazhinji vanopfuura pasi 65 vanewo zvirwere.
- Heredity (mhuri yezvakaitika) - Dambudziko rako rekurohwa rinogona kuva guru kana mubereki, vanasekuru, hanzvadzi kana munun'una ave ane chirwere.
- Race - VaAfrica -America vane ngozi yakawanda kwazvo yekufa kubva kune chirwere chakanyanya kupfuura Caucasians. Izvi zvinokonzerwa nokuti vanhu vatema vane njodzi dzakakwirira dzepamusoro wehutano hwehuropa, chirwere cheshuga nekuderedza.
- Zvepabonde (zvepabonde) - Gore roga rega, vakadzi vane zvirwere zvakawanda kupfuura varume, uye kurohwa kunouraya vamwe vakadzi kupfuura varume. Kushandiswa kwekuberekwa kwemishonga mapiritsi, pamuviri, nhoroondo ye preeclampsia / eclampsia kana gestational chirwere cheshuga, kunyora kunyoreswa kwepabonde, uye kusvuta, uye post-menopausal hormone therapy inogona kuisa njodzi dzinokonzerwa nekurohwa kwevakadzi.
- Pamberi pekurohwa, TIA kana chirwere chemwoyo - Mukana wekurohwa kune munhu anenge atova ane imwe nguva dzakawanda iyo yomunhu asina. Kurwiswa kwezvinyorwa zvisinganzwisisiki (TIAs) "zviratidzo zvekunyevera" zvinounza zvirwere-sezvinoita zviratidzo asi kwete kuora kwekusingaperi. TIAs inopedzisira yakasimba yekurohwa. Munhu anenge ane imwe kana kupfuura TIAs inenge ka10 inowanzoita kuti ave nechirwere kupfuura munhu wezera rimwechete uye zvepabonde asina. Kuziva nekubata maTIA kunogona kuderedza dambudziko rako rekurohwa kukuru. TIA inofanira kuonekwa sechirwere chekukurumidzira uye yakatevedzerwa pakarepo neyanzvi hwehutano. Kana iwe wakanga uine chirwere chemwoyo, iwe uri pangozi yepamusoro yekutora chirwere, zvakare.
Ndiani Anobatwa neRCVS?
RCVS inokanganisa vakadzi kakawanda kupfuura varume, kuva yakawanda kwazvo mushure mekubereka.
Chii Chinokonzera RCVS?
Chikonzero cheRCVS hachizivikanwi, asi chinofungidzirwa kuti chinoguma nekushungurudzika kwemashure kwemasvingo ekugadzira, izvo zvinotungamirira kumagetsi ayo. Zvinhu zvakasiyana-siyana zvakambobatanidzwa neRCVS, kusanganisira:
- Kusarudza serotonin reuptake inhibitors (SSRIs)
- Dzaon decongestants ane pseudoephedrine kana ephedrine
- Ergotamine
- Tacrolimus
- Nicotime patches
- Cocaine
- Marijuana
