Ngaba wakha waxelelwa ngugqirha ukuba wenze "i-vascular ultrasound" okanye "i-vascular mapping"? Mhlawumbi ukhe wenziwa utyando lwe-bypass okanye ukwi-dialysis kuba izintso zakho ziyasilela. Nangona igama lisenokuvakala linzima kancinci, eneneni luvavanyo olulula kakhulu, olungenabuhlungu. Ukuchaneka, "yimephu" ebonisa ngokucacileyo imithambo yegazi emzimbeni wakho. Ngoko masithethe ngayo ngokweenkcukacha.
Ngamafutshane, yintoni iArterial kunye neVenous Mapping?
Oku kubizwa ngokuba yi-'Vein Mapping'. Oku kukwenziwa nge-ultrasound scan. Usenokuba uzibonile iingxelo zeskeni zomama okhulelweyo, kwaye yiteknoloji efanayo esetyenziswa apha. Olu vavanyo luthatha imifanekiso yemithambo yakho yegazi kunye nemithambo yegazi .
Kalula nje:
- Imithambo yegazi emikhulu ethwala igazi elicocekileyo lisuka entliziyweni lisiya kwezinye iindawo zomzimba.
- Imithambo yegazi yimithambo yegazi ethwala igazi elingcolileyo elibuyisela entliziyweni lisuka kwiindawo ezahlukeneyo zomzimba.
Ngoko ke into eyenziwa lolu vavanyo kukudala "imephu" yemithambo yegazi kunye nemithambo engalweni okanye emlenzeni wakho, kubandakanya impilo yemithambo yegazi kunye nemithambo yegazi, isantya sokuhamba kwegazi labo, nokuba bavalekile naphi na, kunye nokuba bakhulu kangakanani. Le mephu ibaluleke kakhulu koogqirha, njengencwadi yesikhokelo.
Kutheni kufuneka senze olu hlobo lovavanyo?
Olu vavanyo lwenziwa ngezizathu ezibini eziphambili: Eyokuqala kukucwangcisa kwangaphambili utyando oluthile , kwaye eyesibini kukufumanisa ngokuchanekileyo izifo ezithile .
Masibone ngokucacileyo ukuba zeziphi ezi mathuba.
| Isihlandlo | Kutheni uvavanyo lubalulekile? |
|---|---|
| Ngaphambi kotyando lwe-coronary artery bypass | Xa umthambo wegazi entliziyweni uvalwe ngamanqatha, kufuneka kudalwe indlela entsha (yokudlula) ukuze udlule kuwo. Oku kwenziwa ngokuthatha umthambo wegazi ophilileyo kwenye indawo yomzimba (ngokuqhelekileyo umlenze) uze uwufake. Ngoko ke ngaphambi kolu tyando, le mephu ibalulekile ukuze kufunyanwe umthambo wegazi olungileyo, onamandla, nophilileyo onokuwufakela kuwo. |
| Ngaphambi kokuba uqale unyango lwe-dialysis (i-Dialysis) | Ukuba umntu onengxaki yezintso aze afumane i-dialysis, igazi kufuneka lithathwe emzimbeni, licocwe ngomatshini, lize libuyiselwe emzimbeni. Oku kufuna indawo yokufikelela apho igazi lihamba khona ngokukhawuleza. Ukuze oku kwenzeke, oogqirha badibanisa umthambo kunye nomthambo engalweni yakho (i-fistula). Ngoko ke olu vavanyo luluncedo kakhulu ekukhetheni umthambo kunye nomthambo olungileyo, onamandla kakhulu. |
| Utyando lwe-Peripheral Vascular Bypass | Njengentliziyo, imithambo yegazi engalweni nasemilenzeni inokuvaleka ngenxa yamafutha agciniweyo. Oku kubizwa ngokuba yiPeripheral Artery Disease (PAD). Kwimeko enjalo, kwenziwa utyando lwe-bypass ukuze kuthintelwe ukuvaleka. Olu vavanyo lwenziwa ukuze kufunyanwe umthambo wegazi ophilileyo. |
| Ukuchonga ezinye izifo | Ikwasetyenziselwa ukuxilonga izifo ezininzi zemithambo yegazi. Umzekelo, ingajonga iimeko ezinje ngokubeka amafutha eludongeni lwemithambo yegazi (atherosclerosis) kunye nokuqhekeka kwegazi kwimithambo yegazi (deep vein thrombosis - DVT). |
Ngubani owenza olu vavanyo?
Olu vavanyo lwenziwa yingcali ye-ultrasound eqeqeshwe ngokukodwa kwi-ultrasound scans. Nguye othatha imifanekiso efunekayo. Emva koko, ugqirha wemithambo yegazi uhlola imifanekiso aze alungiselele ingxelo yakho, ethunyelwa kugqirha wakho onyangayo.
Lusebenza njani olu vavanyo?
Kulula kakhulu. Umatshini we-ultrasound uthumela amaza esandi avakala kakhulu esingenakuwava ngezicubu zomzimba. Amaza esandi ayagxuma emzimbeni aze abuyele umva (evakalayo). Umatshini uthatha amaza esandi abonakalisiweyo aze awaguqule abe yimifanekiso kwiscreen sekhompyutha.
Ukubhala imephu yemithambo yegazi kubandakanya ukuthumela la maza esandi kwindawo apho ikhoyo imithambo yegazi yakho. La maza esandi aphuma kwiiseli ezibomvu zegazi ezihamba ngaphakathi kwimithambo yegazi aze abuyele umva.Lo matshini ulinganisa isantya sokuhamba kwegazi ngokusekelwe kwisantya sokuhamba kwegazi kwaye udala umfanekiso ocacileyo wemithambo yegazi kwisikrini. Unokubona yonke into ukususela kubukhulu bemithambo yegazi, imo yayo, kunye nesantya sokuhamba kwegazi.
Ngaba kufuneka ndilungiselele nantoni na ngaphambi kovavanyo?
Hayi, akukho mfuneko yokulungiselela okukhethekileyo. Ungatya usele ngokwesiqhelo.
Kodwa kukho izinto ezimbalwa ekufuneka uzikhumbule:
- Kuya kufuneka unxibe ilokhwe yesibhedlele ngaphambi kovavanyo.
- Kuya kufuneka ukhulule zonke izacholo ozinxibileyo, ngoko ke kungcono ukuzishiya ekhaya ukuba kunokwenzeka.
- Olu vavanyo ludla ngokwenziwa kwiziko elikhethekileyo lokujonga imifanekiso esibhedlele okanye kwiziko lezempilo.
Ngokwesiqhelo, olu vavanyo luphela lungathatha phakathi kwemizuzu engama-30 ukuya kwengama-90 .
Kwenzeka ntoni ngexesha lovavanyo?
Makhe sijonge okwenzekayo inyathelo ngenyathelo ngeli xesha.
1. Okokuqala, uza kulaliswa etafileni yovavanyo.
2. Okulandelayo, ingcali ifaka ijeli enyibilikayo emanzini kulusu lwendawo evavanywayo (ingalo okanye umlenze). Le jeli ayizukulimaza ulusu kwaye ayizukungcolisa impahla.
3. Emva koko, uza kuthatha isixhobo esincinci esibizwa ngokuba yi-transducer aze asibeke phezu kwendawo egqunywe yijeli aze asihambise siye phambili nangasemva. Esi sixhobo sithumela amaza esandi size sithathe amaza abuyayo. Kwangaxeshanye, imifanekiso yemithambo yegazi yakho yenziwa kwiscreen sekhompyutha.
4. Ingcali iza kuyibamba le sixhobo eluswini ide ibe nayo yonke ingcaciso eyidingayo.
5. Kubalulekile: Ukuba wenza olu vavanyo ngaphambi kotyando, ingcali yetekhnoloji ingaphawula ezinye iindawo eluswini lwakho ngepeni . La manqaku enzelwe ukunceda ugqirha otyandayo ukuba afumane indawo echanekileyo yomthambo wegazi. Musa ukuhlamba la manqaku ngaphambi kotyando nangasiphi na isizathu . Ukuba la manqaku ayaphela emva kokuhlamba, ugqirha otyandayo angakunika ipeni aze akucele ukuba uwafake kwakhona.
Ngaba kukho umngcipheko kule nto?
Hayi. Le yeyona nto ilungileyo ngolu vavanyo. Ukumapha kwemithambo yegazi akubangeli miphumo emibi.
Olu luvavanyo olungenabuhlungu kwaphela, olungenamngcipheko, nolukhuselekileyo. Ngoko ke akukho sizathu sokoyika.
Akukho naliti, dayi, i-anesthesia, okanye iminxeba yolusu emzimbeni wakho. Akukho kuvezwa kwimitha yelanga, njengakwezinye iiskeni, ezifana nee-X-ray.
Ndiza kuyifumana nini ingxelo?
Emva kovavanyo, ingcali iza kuyisula ijeli eluswini lwakho. Emva koko unganxiba ngendlela eqhelekileyo uze uye ekhaya okanye uye emsebenzini. Akukho xesha lokuphumla lifunekayo.
Ingcali yemithambo yegazi iza kuhlola iiskeni zakho, ilungiselele ingxelo epheleleyo, ize iyithumele kugqirha wakho onyangayo. Ugqirha wakho uya kufumana le ngxelo kwiintsuku ezimbalwa. Ngexesha elizayo xa umbona, uya kukuchazela iziphumo.
Nangona kunjalo, ngamanye amaxesha, ukuba kukho imeko engxamisekileyo nesongela ubomi ekrokrelwayo (njenge-DVT), ugqirha angenza olu vavanyo ngokukhawuleza. Kwimeko enjalo, uya kukwazi ukwazi iziphumo ngoko nangoko.
Umyalezo Wokuya Ekhaya
- I-Arterial and Venous Mapping yi -ultrasound scan elula, engenabuhlungu ejonga impilo yemithambo yegazi yakho (imithambo yegazi kunye nemithambo yegazi).
- Oku kudala "imephu" yemithambo yegazi yakho, nto leyo ebaluleke kakhulu koogqirha ukuze bacwangcise utyando kwaye baxilonge izifo.
- Olu vavanyo lunokuba lubalulekile ngaphambi kokuba kuqalwe unyango lwe-dialysis, ingakumbi kutyando lwe-heart bypass .
- Akukho zingozi, iziphumo ebezingalindelekanga, okanye imitha echaphazelekayo kolu vavanyo, ngoko ungakhathazeki ngayo.
- Emva kovavanyo, thetha ngokukhululekileyo nogqirha wakho malunga neziphumo zakho kunye namanyathelo alandelayo. Ungathandabuzi ukubuza nayiphi na imibuzo onayo.
