Chorionic villus sampling

Chorionic villus sampling (CVS) bvunzo vamwe vakadzi vane nhumbu vanofanirwa kuongorora vacheche vavo kumatambudziko egene.

CVS inogona kuitwa kuburikidza nemuromo wechibereko (transcervical) kana kuburikidza nedumbu (transabdominal). Miscarriage mitengo yakakwira zvishoma kana bvunzo dzaitwa kuburikidza nemuromo wechibereko.

Iyo transcervical maitiro inoitwa nekuisa iyo yakatetepa epurasitiki chubhu kuburikidza nemukadzi uye cervix kusvika kune placenta. Wako wekuchengeta hutano anoshandisa mifananidzo ye ultrasound kuti abatsire kutungamira iyo chubhu munzvimbo yakanakira sampling. Muenzaniso mudiki wechorionic villus (placental) tishu inozobviswa.

Iyo nzira yekuchinja-shanduka inoitwa nekupinza tsono kuburikidza nemudumbu uye muchibereko uye mune iyo placenta. Ultrasound inoshandiswa kubatsira kutungamira tsono, uye hushoma huturu hunodhonzwa musirinji.

Muenzaniso unoiswa mundiro uye unoongororwa murabhu. Mhedzisiro yekutora inotora angangoita mavhiki maviri.

Wako mupi anotsanangudza maitiro, njodzi dzacho, uye dzimwe nzira senge amniocentesis.

Iwe unozobvunzwa kusaina fomu rekubvuma pamberi peiyi nzira. Unogona kukumbirwa kupfeka hanzu yechipatara.

Mangwanani enzira yacho, unogona kukumbirwa kunwa zvinwiwa uye kurega kuita weti. Kuita izvi kunozadza dundira rako, izvo zvinobatsira mupi wako kuona kwaanganyatsotungamira tsono.

Udza mupiki wako kana iwe uri weergoria kune iodine kana shellfish, kana kana iwe uine chero humwe hutachiona.

Iyo ultrasound haina kukuvadza. Girazi rakajeka, rine mvura rinoiswa paganda rako kuti ubatsire nekufambisa masaisai ezwi. Prote yakabatwa ruoko inonzi transducer inozotamisirwa pamusoro penhumbu yako. Uye zvakare, mupi wako anogona kuisa kumanikidza padumbu rako kuti uwane chinzvimbo chechibereko chako.

Iyo gel inonzwa kutonhora pakutanga uye inogona kutsamwisa ganda rako kana isina kushambidzwa mushure mekuita.

Vamwe vanhukadzi vanoti kusangana nekutsi kwemukadzi kunonzwa kunge bvunzo dzePap nekumwe kusagadzikana uye kunzwa kwekumanikidzwa. Panogona kunge paine shoma shoma yekubuda ropa mushure mekuita maitiro.

Chiremba wechiremba anogona kuita izvi mumaminitsi mashanu, mushure mekugadzirira.

Muedzo unoshandiswa kuratidza chero hutachiona hutachiona mumwana wako asati aberekwa. Izvo chaizvo chaizvo, uye zvinogona kuitwa kutanga kwazvo pakubata.

Matambudziko eGenetic anogona kuitika mune chero nhumbu. Nekudaro, zvinotevera zvinhu zvinowedzera njodzi:

• Amai vakura
• Nhumbu dzakapfuura nenjodzi matambudziko
• Nhoroondo yemhuri yezvinetso zvemagene

Genetic counselling inokurudzirwa usati waitwa. Izvi zvinokutendera iwe kuti utore isina kumhanyisa, ruzivo rwakasarudzika nezve sarudzo dzekusununguka kubatwa.

CVS inogona kuitwa nekukurumidza pakuzvitakura kupfuura amniocenteis, kazhinji kazhinji pamasvondo gumi kusvika gumi nemaviri.

CVS haina kuona:

• Neural tube zvikanganiso (izvi zvinosanganisira musana wechipfuva kana huropi)
• Rh kusapindirana (izvi zvinoitika kana mukadzi ane nhumbu aine ropa reRh-negative uye mwana wake asati aberekwa aine ropa reRh).
• Kuremara kwekuzvarwa
• Nyaya dzine chekuita nebasa rehuropi, senge autism nekuremara kwepfungwa
  
  

Mhedzisiro mhedzisiro zvinoreva kuti hapana zviratidzo zvekuremara kwemajini mumwana ari kukura. Kunyangwe hazvo mhedzisiro yekuyedza iri yechokwadi, hapana bvunzo iri 100% chaiyo pakuyedza kwematambudziko ezvemuzvirwere.

Uyu muedzo unogona kubatsira kuona mazana ezvinetso zvekuberekwa. Mhedzisiro isina kujairika inogona kunge iri nekuda kweakawanda akasiyana magene maitiro, anosanganisira:

• Down chirwere
• Hemoglobinopathies
• Tay-Sachs chirwere

Taura nemupi wako nezve zvinorehwa nemimwe miedzo yako. Kumbira mupiki wako:

• Mamiriro acho kana hurema hunogona kurapwa chero panguva kana mushure mekuzvitakura
• Ndezvipi zvakakosha zvinodiwa nemwana wako mushure mekuzvarwa
• Ndezvipi zvimwe zvaunogona kuita nezvekuchengetedza kana kupedza kubata kwako

Njodzi dzeCVS dzakangokwirira zvishoma pane aya amniocenteis.

Zvinogona kuitika zvinosanganisira:

• Kubuda ropa
• Utachiona
• Kusununguka (kusvika kusvika 1 pavakadzi zana)
• Rh kusapindirana muna amai
• Kubvaruka kwemavara izvo zvinogona kutungamira mukuparara

Kana ropa rako riri Rh negative, unogona kuwana mushonga unonzi Rho (D) immune globulin (RhoGAM nemamwe mabrand) kudzivirira Rh kusapindirana.

Iwe uchagamuchira yekutevera-up ultrasound mazuva maviri kana mana mushure mekuita maitiro kuti uve nechokwadi chekuti nhumbu yako iri kuitika zvakajairika.
