Simila we plexus choroid: Izimbangela Nezingozi Ukwelashwa

Simila kumiswa okuthiwa i-plexus choroid ebuchosheni, okuyinto ukutholwa ultrasound ku-fetus at inyanga 6-7 sokuthuthuka. Ngemva kwalokho kumelwe zinyamalale nokuningi ngami neze zifane. Nokho, ngemva kokwamukela ngemiphumela yocwaningo kwabesifazane abakhulelwe uqale ukukhathazeka futhi ucabangele lokhu ukuphambuka. Empeleni akunjalo. Ngo nginesimila ezinjalo, nesuka ebuchosheni phakathi kwengane esiswini, akukho usongo enganeni. Noma impilo yakhe noma ukuthuthukiswa akuyona engozini.

Kuyadingeka ukuba ukuhlukanisa nginesimila, okuyinto has a umsuka semithambo. Okungukuthi, walibumba is e ketshezi cerebral emva unhlangothi, isifo sokuvuvukala kwemithambo, ukutheleleka. Okungukuthi, is phetho isifo iphutha emzimbeni. Kulesi sihloko, siyowuqonda, uyini choroid plexus simila.

Incazelo imfundo

Simila e Umhlinzi (choroid, horioidnom villous) plexus kwakhiwa hhayi kaningi. Ngokuvamile, kuba% 1-3 kuphela azo zonke ukukhulelwa, okuyinto ehlolwa. Lokhu imfundo kufanele zinyamalale kumaviki awu 27-28 esesibelethweni. Half of the izinhlumba kukhona zamazwe amabili. Kodwa kukhona izimo lapho simila libonakala ngaphambi kwezidingo. Lokhu kubuye akuyona into enkulu.

Isithelo akuyona asengozini. Ngaphezu kwalokho, uma kutholwa ke nosana noma umuntu omdala (a Ezimweni ezingavamile kakhulu, kuyisici esihlupha umuntu kukho konke ukuphila), akusizi. Izinhlumba we plexus choroid kungaba ezimbalwa, ayithinti onalesi sifo.

Kuyini lokhu plexus simila choroid? Ngaphakathi plexus iqoqa cerebrospinal fluid noma CSF, ukuthi likhiqizwa ngaluphi. It uyasondla ubuchopho nomgogodla umbungu. Umhlinzi plexus - uphawu ekuqaleni we CNS kwetinhlavu-embryo yoke, lapho bobabili, njengoba ama- cerebral (sokunene nesobunxele).

Isayensi akazi ngasiphi isizathu uketshezi ekuqongeleleni itholakala endaweni ethize. Deal akwenzi mqondo. Phela, leli choroid plexus simila ku-fetus akunandaba ngempela. It is abizwa kanjalo ngenxa ku ultrasound ukuminyana ahunyushwe ngayo leli fomu.

Ingabe ikhona ubuhlobo zokugula wokukhula kwengane esiswini?

ngezinye izikhathi Medical imithombo izincwadi bamele Imininingwane yokuthi ukuxhumana phakathi simila kanye plexus choroid we zokugula fetus khona. Ukuze lokhu kungaholela, isibonelo, a kwezakhi.

Lapho ehunyushelwe choroid plexus simila (ngakwesokunene, kwesokunxele noma zombili), akunandaba. Kubalulekile ukwazi ukuthi kukhona ukuhlobana, kodwa emuva. Yileyo choroid plexus simila aliholeli anomalies yentuthuko, kodwa kunalokho, ukuphazamiseka azalwa naso umbungu kubangela ukwakheka izinhlumba izitsha. Kodwa lezi akusho ephelezelwa izinqubo okungafanele sokugembula.

Lokho esihambisana choroid plexus simila e nosana?

Cabanga njalo kunazo kutholakala ukuthi uphethwe yini isici zofuzo, ephelezelwa khona izinhlumba. Kuyinto syndrome, Edwards noma trisomy 18. Kulesi chromosomal anomaly pair 18 akuyona etshiyeneyo, it is yengezwa kwenye chromosome 18. Ngakho, uma yabo evamile ezimbili, ngoba isifo inikezwe ukujikisa okuthathu. Ngo umbungu okuholela genotype siqukethe Ama-chromosomes e-47.

Ikhophi chromosome 18 kungabangela ukufa fetus noma kokuzalwa kwengane yakho uzobe ubuhanjelwe ukukhubazeka amaningi kanye anomalies. Lokhu kuphakamisa:

• kwemizwa tube ukukhubazeka;
• izinyawo Hammerhead;
• torsion yeminwe;
• hygroma simila;
• iphimbo;
• micrognathia;
• Foot rocker;
• ukukhula elinganiselwe.

Ngezinye izikhathi ngisho trisomy 21 , noma i-Down Syndrome kodwa ngasizathu simbe, kwakheka, lo simila we plexus choroid zobuchopho incane isifo inikezwe.

Ukubaluleka izinhlumba zero ngisho ne Edwards syndrome, njengasezulwini Ibaluleke ngani ukuphambuka ohambisana kakhulu ekuthuthukeni kwale anomaly.

Izici choroid plexus izinhlumba

Ngakho, ngokuvumelana ngenhla, singakwazi iziphetho ezilandelayo:

• ayibalulekile, ngakwesokunene noma ngakwesobunxele;
• Kunendaba noma ungubani imelelwa zokwakheka ezincane eziningana;
• ngaleyo ndlela kuphephile;
• alinaso umsebenzi;
• akazibandakanyi iyiphi izinqubo ezibalulekile;
• It is hhayi ezikhulayo futhi akaphinde azalwe engomunye.

Omama abakhulelwe akufanele wesabe uphethwe "plexus simila semithambo yobuchopho," noma cabanga kwezinye zokwakheka fibrosis. Amagama ingase isebenze ngendlela efana, kodwa nge ilungiselelo ezahlukene kanye genesis.

Okunye simila semithambo

Kubalulekile ukuqaphela ukuthi ezigabeni kamuva yokukhulelwa nezinye izinhlangano izitsha kungatholakala. On fetus ubuchopho ultrasonography ibukeke hhayi choroid plexus simila. Ngalokho-ke angakhuluma?

izinhlumba ezinjalo zibonisa kuleli cala ukuthi unina kwadingeka isifo noma ingabe sisekhona. Lezi zifo zihlanganisa cytomegalovirus futhi herpes igciwane.

Kodwa lokhu akulona nginesimila plexus semithambo yobuchopho ku-fetus.

Umhlinzi futhi ramolitsionnaya (etholakala ubuchopho imfuyo) simila, elisetendeni ezigabeni kamuva, lubonisa ukuthi ubuchopho sesakhiwe kakade, futhi kuwo kukhona izimbotshana fibrosis ngenxa ukutheleleka igciwane.

A usana kungaba batheleleke nge igciwane ngenkathi bedlula lokuzalwa canal kamama. Khona-ke ukwakheka fibrosis, amaningi futhi ngokuvamile itholakala ezindaweni yesikhashana futhi okuqondile ubuchopho, uzohlonzwa emva kokuzalwa. Uma nginesimila uvela foci of necrosis, ibizwa ngokuthi ramolitsionnoy.

Kuqeda izicubu emsipheni ngenxa yokulimala herpes noma cytomegalovirus. Izinhlumba semithambo plexuses we ventricles lateral njengoba hhayi kwakhiwa.

neurosonography

plexus Microcysts choroid zingatholakala ku-ultrasound, ngesikhathi neurosonography. Njalo izinyane ukuba ngonyaka kufanele kudlule kokutshelwa ngokukhubazeka kwengane. On US kuchazwe iziyaluyalu zezinzwa.

Neurosonography liyadingeka kulezi zimo ezilandelayo:

• Ukuzalwa ukulimala.
• Uma kwenzeka izinsolo ngoba khona ukutheleleka fetus.
• Ekukhulelweni ezinzima.
• Endabeni ka wazalwa kungakabi isikhathi.
• Lapho ngeziphambeko isisindo obelusanda kuzalwa ngosayizi.
• Uma kukhona ukwephulwa abalulekile isakhiwo kanye ukuma ikhanda, ebukhoneni kwezinso e anatomy kwezitho.

ukuba nombono ongafani ngeke

Isizathu, kwasendaweni kanye nosayizi izinhlumba kuthinte Izibikezelo egunjini lokuhlolwa kwezifo. The njalo kunazo ebekiwe PCR zokuxilonga ukuthola ejenti ezibangelwa amagciwane. Uma ukuhlaziywa inguyebo, kudingeka yokwelapha othize kanye nokuqapha olwengeziwe.

Ngezinyanga ezintathu, khona-ke izinyanga eziyisithupha kanye nonyaka ukwenza i-ultrasound yobuchopho (ultrasonography cranial) ingane. Ukubikezela ikakhulukazi evumayo, kungakhathaliseki ukuthi akhonjwe igciwane lohlobo. Le mfundo esikhathini esingangonyaka zinyamalale nezobakhumbuza zalo. Ayikho uyahluleka uma elwa nokuphuza kungenzeki.

Uma sikhuluma ramolyatsionnoy simila, kungase futhi zinyamalale isakhasa ngokuphelele. Uma kungenjalo, uma ezinye izizathu ukuthi iziphatha ngendlela ehlukile. Kodwa-ke ungeke ukuyibiza nginesimila. Lokhu kumiswa kuphakama ngenxa yokwephulwa izindonga isitsha, futhi itholakala izicubu ingqondo.

izici ngodlame

simila sokugembula bangase bafinyelele ngenxa nezinye izinto:

• Ezithathelana.
• IsiZulu kanye nezinye ukulimala.
• Microstroke.
• Oluhambisana unhlangothi (simila ubuyisela hematoma, kwakheka ngenxa yokulimala semithambo).
• unhlangothi Ischemic (remolitsionnaya simila umsuka semithambo imiphumela nje kusukela necrosis).
• Aneurysms.

Ngokuvamile, uma esilimele odongeni, kuzoba i ekhipha igazi enhliziyweni. Ngempela, lezo zinqubo, ngemithambo awahlanganyeli.

izimpawu zokwelapha

Hematoma, unhlangothi, isifo sokuvuvukala kwemithambo angase avuse nginesimila ebuchosheni. Kwezinye izimo, akukho uphawu yale mfundo, futhi zingatholakala kuphela ngemva kokufa komuntu. Kodwa kanye simila kwakhiwa kusukela igciwane, ungaveza ezinye zezimpawu:

• Izimpawu Hyper e izinsana.
• Umuzwa kokucindezelwa zobuchopho, ikhanda.
• A ukuzwa futhi ongaboni.
• Iya kancane ataxia.
• zesifo sokuwa, okuyinto kubhekwa nemiphumela emibi kakhulu.

Izinhlumba we choroid plexus ventricle izimpawu ezinjalo ungayeki.

izimpawu ezengeziwe

Ngaphezu kwalokho, kokucindezelwa njalo ijwabu ubuchopho kungaholela kwezinye izici:

• njalo ubuhlungu ezidabukile ekhanda okujula nobude obuhlukahlukene;
• Ukwephula kwemigwamanda enesibopho ukuzwa, ukuhogela futhi wabona;
• ukozela noma, Ngakolunye uhlangothi, ukuqwasha;
• izinkinga nge ngefanelo nangokuvumelana;
• imisipha hypotonia; Ripple futhi umsindo uzizwa ekhanda, ingcindezi ephakeme ngaphakathi skull;
• okungazelelwe yokufikelwa njalo kanye nokugoqana;
• eliqhaqhazelayo;
• regurgitation;
• umuzwa yezwakala e fontanel ukuvuvukala;
• ukukhubazeka lendawo izingalo noma imilenze, ukungabi namizwa nemilenze ephelele.

Ukubukeka izimpawu zokwelashwa senziwa kokucindezelwa kwezicubu eduze. It kwaphazamisa ukusebenza evamile ingqondo. Ngakho kwenzekani lapho ezinkulu usayizi izinhlumba noma ukuyithola sisondele kakhulu izikhungo ebalulekile umsebenzi ephakeme sezinzwa. Ngu ukufuduka kuholela kahle kwegazi futhi hypoxia.

zokwelapha

Noma iyiphi inqubo yokwelapha esikhethekile nginesimila ebuchosheni, + njengasosukwini lokungivivinya choroid plexus simila ayidingekile. Kodwa ukuthola i-herpes, cytomegalovirus ukutheleleka noma ezinye aqokwe yokwelapha namagciwane. Uma kukhona ukuquleka, sikhonjiswa sidla tidzakamiva izakhiwo anticonvulsant.

Kufanele kuphawulwe ukuthi uma ukwelashwa ngoludala engalethi Imiphumela (simila we plexus choroid zobuchopho umbungu likhulu kakhulu, isibonelo), aye ayisebenzisa kaningi ukuhlinzwa. Iziko le-siqedwa esebenzisa ukusebenza. Ngemva kwalokho, njengoba umthetho, shiya zonke izimpawu.

Nge unezimpawu ezikahle kanye nezikhalo ezingavamile ngesineke isiyezi, ubuhlungu bekhanda, okuyinto ukugxisha uhlamvu, wagunyaza ende Yiqiniso ukwamukela "tsinarizin" futhi "Cavinton". Izidakamizwa kungaba ngokuphawulekayo ngcono ingqondo umoya-mpilo umncane, ukusungula okhathazekile kwegazi, kujwayeleke kwemizwelo. Kudluliselwe avame kahle, side effects musa abangele. Kodwa kungenzeka isici esiyingqayizivele.

Sixoxe ngokuningiliziwe choroid plexus simila, kanye umehluko zako ezisemqoka ezivela kwezinye zokwakheka fibrosis.
