Sawubona msizi wethu. Namuhla sizoxoxa ngendaba ebaluleke kakhulu ephathelene nomzimba wakho, ikakhulukazi izinyawo nemilenze yakho esebenza kanzima usuku lonke. Wake waphawula ukuthi abanye abantu banemithambo eluhlaza okwesibhakabhaka noma onsomi emilenzeni yabo, ikakhulukazi endaweni yezinsini? Mhlawumbe nawe kuye kwadingeka ume usuku lonke emsebenzini noma esitolo, bese kusihlwa imilenze yakho izizwa ivuvukele, isinda, futhi ibuhlungu kakhulu. Abaningi bethu bacabanga ukuthi lezi yizinto ezivamile ezizihambela zodwa, akunjalo? Kodwa ngemuva kwalokhu kunendaba enkulu ngohlelo lwemithambo olubaluleke kakhulu oluqinisekisa ukuthi igazi ligeleza kahle emzimbeni wethu. Lo mlingiswa oyinhloko kuleyo ndaba ngumthambo omude kunayo yonke emzimbeni wethu, okuyi-saphenous vein noma esiwubiza ngokuthi umthambo we-saphenous.
Njengodokotela bakho abaseduze, sifuna ukuba uqonde ukuthi lesi simiso sisebenza kanjani, yini engaya phansi, nokuthi ungayigcina kanjani imilenze yakho iphilile. Asiye endabeni yethu ngokuningiliziwe, akunjalo?
📌 Okubalulekile Okumele Ukukhumbule
- Umthambo we-saphenous yiwona mthambo omude kunayo yonke emzimbeni womuntu, osuka onyaweni uze ufike ethangeni.
- Umsebenzi wawo omkhulu ukuqoqa nokubuyisela igazi elingenawo umoya-mpilo lisuka emilenzeni libuyisele enhliziyweni nasemaphashini.
- Izinkinga kule mithambo zingabangela ukuvuvukala, ubuhlungu, nemithambo egobile eyaziwa ngokuthi ama-varicose veins.
- Kwezinye izikhathi, le mithambo isetshenziswa odokotela abahlinzayo ekuhlinzweni kokuxhunyezwa kwemithambo yenhliziyo (coronary artery bypass).
- Ukuzivocavoca umzimba, ukuphuzwa kwamanziane, nokugwema ukuma isikhathi eside kusiza kakhulu ekugcineni le mithambo iphilile.
Kalula nje, iyini i-Saphenous Vein?
Kulungile, ake sikubeke kanje ngendlela elula. Imithambo yegazi ethambile yimithambo esiza ekuthwaleni igazi lisuka emilenzeni yakho libuyele enhliziyweni yakho. Lena imigwaqo emincane eholela kusukela ezinyaweni zethu iye ezinhliziyweni zethu. Sinezinhlobo ezimbili ezinkulu zemithambo ye-saphenous emlenzeni ngamunye wethu:
- I-Great Saphenous Vein (Umthambo Omkhulu We-Saphenous): Eyaziwa nangokuthi yi-Long Saphenous Vein, lena yi-vein ende kunazo zonke emzimbeni wethu. Cabanga nje, uqala onyaweni lwakho, ugijime ngaphandle komlenze wakho, ukhuphuke udlule ngaphansi kwedolo, uze ufike phezulu ethangeni lakho.
- I-Small Saphenous Vein (Umthambo Omncane We-Saphenous): Lo mthambo uqala ngemuva kwezinyawo, ugijimela ngemuva komlenze wakho ongezansi, bese uphela ngemuva kwedolo lapho uhlangana khona neminye imithambo ejulile.
Yomibili le mithambo yenza umsebenzi omkhulu kakhulu nsuku zonke ukwenza isiqiniseko sokuthi igazi alihlali endaweni eyodwa emilenzeni, akunjalo? Ake siphinde sicabange ngalokhu: awuvali amehlo lapho ucabanga ngomsebenzi wazo, ngoba zisebenza ngisho nangesikhathi ulele.
Uyini ngempela umsebenzi walesi simiso semithambo yegazi?
Umthambo wakho we-saphenous, njengeminye imithambo eminingi emzimbeni wethu, uthwala igazi "elingcolile" eliphelelwe umoya-mpilo ulibuyisele enhliziyweni. Imithambo ye-saphenous iqoqa igazi emithanjeni emincane ezinyaweni nasemilenzeni yethu. Le mithambo ibe isithwala leli gazi iye emithanjeni emikhulu emilenzeni ephezulu.
Ukusuka lapho, igazi liya phezulu emlenzeni, ekugcineni lijoyina omunye wemithambo eyinhloko emzimbeni wethu, i-Inferior Vena Cava, eya ngqo enhliziyweni. Lonke lolu hlelo luyingxenye yesimiso sethu sokujikeleza kwegazi. Cabanga ngalo njengenethiwekhi yemigwaqo emikhulu edolobheni lakithi elikhulu, lapho izimoto zihamba khona zingami.
Igazi yizimoto ezihamba kule migwaqo. Lezi zimoto zinomsebenzi oqhubekayo okufanele ziwenze, okungukuthi ukuthwala umoya-mpilo nezakhamzimba kuwo wonke amaseli nezicubu zomzimba wethu. Lokhu kwenzeka ngaphandle kokuma umzuzu owodwa nje. Pho kungani leli gazi kufanele libuyele enhliziyweni? Isizathu siwukuthi njalo lapho inhliziyo ishaya, inhliziyo ipompa leli gazi elingenawo umoya-mpilo liye emaphashini. Kusemaphashini lapho leli gazi liphinde lifakwe umoya-mpilo khona bese kususwa i-carbon dioxide engafuneki.
Igazi "elihlanzekile", elicebile ngomoya-mpilo, libuyela enhliziyweni. Inhliziyo ibe isipompa lelo gazi emzimbeni wonke ukuze uphile futhi ube namandla. Ngemva kokujikeleza emzimbeni wonke nokusabalalisa umoya-mpilo, igazi elingenawo umoya-mpilo libuyela emithanjeni bese liqala uhambo lwalo olubuyela enhliziyweni. Lo mjikelezo uyaqhubeka ngokungapheli empilweni yakho yonke, akumnandi yini ukucabanga ngalokho?
Kuyiqiniso yini ukuthi lo mthambo usetshenziselwa ukuhlinzwa kwenhliziyo?
Yebo, le ndaba iyiqiniso futhi iyisimangaliso sezokwelapha. Ngezinye izikhathi, uma izinzwa noma imithambo yegazi ezungeze inhliziyo yakho (coronary arteries) zivalelekile ngenxa yamafutha noma ezinye izinkinga, odokotela abahlinzayo bathatha ingxenye yomthambo wakho we-saphenous (ngoba mude futhi unamandla) bese beyisebenzisa "njengesixhumi" noma indlela entsha yokudlulisa igazi enhliziyweni yakho. Lokhu kuyiqiniso ikakhulukazi ngesikhathi sokuhlinzwa okubizwa nge-coronary artery bypass graft (CABG).
Lapho udokotela ethatha ingxenye yaleli gazi emlenzeni wakho, iminye imithambo emlenzeni iyathatha lo msebenzi futhi umzimba uyakwazi ukuzivumelanisa naleso simo kahle kakhulu. Ingabe bewazi ukuthi umzimba wethu ungaqina kangaka uma udinga usizo? Yebo kunjalo!
Uphi lo mthambo futhi wakhiwa kanjani?
Ake sibheke ukuthi lo mthambo umi kanjani futhi uqala kuphi. I-Great Saphenous Vein iqala ngemuva nje kwesandla sonyawo lwakho (ngaphansi kwezinhlangothi zangaphakathi), ikhuphuke idlule ngaphansi kwe-ankle (iqakala lakho), iqhubeke ngaphakathi komlenze wakho, idlule ngaphakathi kwedolo, bese iqonde phezulu ethangeni lapho ihlangana khona nomthambo omkhulu ogijima ezingeni le-groin (ethangeni eliphezulu eduze kwesisu).
Ngaphakathi kule mithambo, kunamavalvi amancane kakhulu (valves) asebenza njengezicabha noma amasango. Umsebenzi walamasango ukuvumela igazi ukuthi linyuke liyiye enhliziyweni kuphela, futhi avimbele igazi ukuba lingabuyeli phansi ngenxa yamandla adonsela phansi (gravity). Uma la mavalvi ebuthakatha noma eba buthakathaka, yilapho kuqala khona izinkinga ezifana nokuvuza kwegazi nokuvuvukala.
Izimo ezivamile ezithinta umthambo we-saphenous
Njengazo zonke izingxenye zomzimba wethu, umthambo we-saphenous ungaba nezinkinga ezithile ngokuhamba kwesikhathi. Phakathi kwezimo ezivame kakhulu sithola:
- I-Chronic Venous Insufficiency (CVI): Lesi simo senzeka lapho amavalvi asemthanjeni engasebenzi kahle, okwenza igazi libuye futhi liqoqekile emlenzeni, okuholela ekuvuvukaleni nasekubuhlungu.
- Ama-Varicose Veins (Imithambo Egobile): Lezi yimithambo eba nkulu, egobile, futhi ebonakala ngaphandle kwesikhumba ngombala oluhlaza okwesibhakabhaka noma onsomi, ovame ukuhlotshaniswa nobuhlungu noma ukuzizwa usinda emilenzeni.
- I-Superficial Thrombophlebitis: Ukuvuvukala komthambo oseduze kwesikhumba kanye nokwakheka kwamacwecwe egazi (blood clot) ngaphakathi kuwo, okuvame ukubangela ubuhlungu obukhulu nokuqina kwesikhumba esifundeni esithintekile.
Wazi kanjani ukuthi kunenkinga ngalo mthambo? (Izimpawu)
Kulula ukuziba lezi zimpawu ekuqaleni, kodwa uma uzwa lezi zinto ezilandelayo, kufanele unake kakhulu:
