Ngaba wakha weva ngesixhobo esithumela isixhobo esincinci esifana nekhamera ngaphakathi komthambo wegazi emzimbeni wethu size sihlole imeko yeendonga zawo zangaphakathi? Yiteknoloji emangalisayo ngokwenene. Mhlawumbi ukhe weva nge-angiogram, edla ngokusetyenziselwa ukujonga ukuvaleka okanye ukubekwa kwe-cholesterol kwimithambo yegazi yentliziyo. Kodwa namhlanje siza kuthetha ngovavanyo olukhethekileyo olunokuba nzulu ngakumbi, kwaye olunokubona ngokucacileyo ukuba kwenzeka ntoni ngaphakathi kodonga lomthambo wegazi. Oku sikubiza ngokuba yi -Intravascular Ultrasound (IVUS) .
Ngamafutshane, yintoni i-Intravascular Ultrasound (IVUS)?
Khawucinge ukuba umbhobho wamanzi endlwini yakho uvalekile. Kodwa awukwazi ukubona ngaphandle ukuba uphi, uvalekile kangakanani, okanye ukuba iindonga ezingaphakathi kombhobho zonakele na, akunjalo? Yiyo loo nto kunjalo ngemithambo yethu yegazi. I-IVUS, ukuba sithetha inyaniso, sisikena esincinci esinokuthunyelwa ngaphakathi kwimithambo yegazi.
Oku kuquka ukusebenzisa amaza esandi ukuhlola izicwili ezithambileyo ngaphakathi kwemithambo yegazi. Isixhobo esibuthathaka kakhulu esenzelwe le njongo sithatha imifanekiso yexesha langempela ngaphakathi kwemithambo yegazi. Olu vavanyo lusetyenziswa kakhulu ukujonga imeko yemithambo yegazi yentliziyo , ehambisa igazi entliziyweni. Nangona kunjalo, ukuba kuyimfuneko, le ndlela ingasetyenziselwa ukuhlola eminye imithambo yegazi emzimbeni.
Olu vavanyo lubizwa nangamanye amagama aliqela:
- I-ultrasound yemithambo yegazi ye-coronary
- I-ultrasound ye-Endovascular
- I-echocardiography ye-Intravascular
Isebenza njani le teknoloji? Iyamangalisa!
Indlela esebenza ngayo le nto ilula kakhulu kwaye iyamangalisa. Cinga ngendlela ilulwane elibhabha ngayo emqolombeni omnyama lingabetheki eludongeni. Ilulwane likhupha isandi, kwaye xa libetha umqobo lize libuye (isandi), ilulwane liyasiva kwaye liqonde okuzayo. Itekhnoloji ye-IVUS ifana nale.
1. Ukufakwa kwe-catheter: Okokuqala, ugqirha ufaka ityhubhu encinci kakhulu, eguquguqukayo, ebizwa ngokuba yi-catheter , kwimithambo yegazi ngokusebenzisa umngxuma omncinci emqolo okanye engalweni yakho. Uza kunikwa amayeza okukwenza ungabi nazintlungu kwindawo yokufakwa kwe-catheter, ukuze ungabi nantlungu.
2. I-Ultrasound Probe: Ekupheleni kwale catheter kukho iqhawe lebali lethu, i- ultrasound probe encinci. Le incinci kakhulu.
3. Ukuthumela amaza esandi: Ugqirha uhambisa le catheter ngononophelo ecaleni kwemithambo yegazi ukuze ihlolwe. Njengoko ihamba, iprobe ikhupha amaza esandi asebenza rhoqo.
4. Ukuphinda kuthathwe isandi: La maza esandi aphuma eludongeni lomthambo wegazi aze abuye, njengakwibali lelulwane.
5. Uyilo lwemizobo yekhompyutha:Iimpendulo ezibuyayo zihlalutywa yikhompyutha kwaye ziguqulwa ngoko nangoko zibe yimifanekiso ecacileyo, enqamlezileyo yangaphakathi komthambo wegazi. Kungokujonga le mifanekiso apho ugqirha anokukwazi ukuvavanya ngokuchanekileyo imeko engaphakathi komthambo wegazi.
Ngamafutshane, le ndlela ikuvumela ukuba ungene ngaphakathi kwimithambo yegazi uze ubone i-millimeter nge-millimeter ukuba iindonga zayo zinobukhulu kangakanani, ukuba i-cholesterol ibekwe na, kunye nokuba ingakanani indawo igazi elinokuthi lihambe kuyo.
Uvavanyo lwe-IVUS lungandinceda njani?
Ukuba ugqirha ukrokrela ukuba imithambo yakho yegazi ivalekile okanye inciphile, uvavanyo lwe-IVUS lunokuba luncedo kakhulu. Lunokunceda ekulawuleni iimeko ezinzulu nezisongela ubomi ezifana nohlaselo lwentliziyo, i-pulmonary embolism, kunye ne -stroke .
Makhe sijonge le theyibhile ingezantsi ukuze sibone ukuba uvavanyo lwe-IVUS lubanceda njani oogqirha.
| Indawo yokujonga | Ingcaciso efunyenwe yi-IVUS |
|---|---|
| Ukubekwa kwe-cholesterol (i-atherosclerosis) | Ingalinganisa ngokuchanekileyo ukuba i-cholesterol, amafutha, kunye nezinye izinto zibekwe (i-plaque) eludongeni lwemithambo yegazi, kwaye ukuba kunjalo, ingaba inzima kangakanani. |
| Ucwangciso lonyango | Olu lwazi lubalulekile ekuthatheni isigqibo sokuba ngaba isigulana kufuneka sibekelwe i-stent okanye senze utyando olukhulu olufana notyando lwe-coronary artery bypass . |
| Ukubekwa kweStent | Ukuba kufakwa i-stent (isixhobo esifana ne-mesh esibekwa ukugcina umthambo wegazi uvulekile), i-IVUS inceda ekukhetheni ubungakanani obuchanekileyo be-stent nokuqinisekisa ukuba inamathele ngokufanelekileyo eludongeni lomthambo. |
| Ezinye izinto ezinobungozi | Olu vavanyo lukwasetyenziselwa ukubona iimeko ezifana nokuqhekeka kwegazi, i-aortic aneurysm, kunye nesifo semithambo yegazi engaphandle. |
Yintoni umahluko phakathi kwe-IVUS kunye ne-Angiogram?
Lo ngumbuzo abantu abaninzi abanawo. I-angiogram ihlola imithambo yegazi evalekileyo, kwaye i-IVUS yenza into efanayo, ngoko ke yintoni umahluko phakathi kwezi zimbini?
Khawucinge ukuba uhamba esitalatweni uze ubone isithunzi somntu emhlabeni. Ngokujonga eso sithunzi, ungafumana umbono ongeyonyani ngemilo yomntu. I-angiogram yinto efana naleyo. Ibandakanya ukufaka idayi ekhethekileyo kwimithambo yegazi uze uthathe umfanekiso we-X-ray. Emva koko sibona kuphela 'isithunzi' segazi elihamba ngaphakathi kwimithambo yegazi. Oko kukuthi, umfanekiso onemilinganiselo emibini (2D).
Kodwa i-IVUS ayifani nokujonga isithunzi. Kufana nokusika isonka sibe ziingceba, uthabathe isilayi esinye uze uhlolisise okungaphakathi. Nge-IVUS, sifumana icandelo elinqamlezileyo lomthambo wegazi, umbono onemilinganiselo emithathu (3D). Emva koko sinokubona ngokucacileyo iinkcukacha ezininzi ezingenakubonwa yi-angiogram, njengeeleya zodonga lomthambo wegazi, indlela i-cholesterol ebekwe ngayo, kunye nobukhulu bayo.
Indlela uvavanyo olwenziwa ngayo: inyathelo ngenyathelo
Abanye abantu banokoyika kancinci xa besiva ngolu vavanyo. Kodwa eneneni lwenziwa ngaphandle kokungonwabi. Lwenziwa ngugqirha wentliziyo oyingcali (Interventional Cardiologist) okanye ngugqirha wemithambo yegazi (Vascular Surgeon) .
Ngokwesiqhelo, xa kuhlolwa imithambo yegazi yentliziyo, olu vavanyo lwe-IVUS lwenziwa njengenxalenye yovavanyo lwe -cardiac catheterization . Oku kuvumela ukuba ezinye izinto ezininzi entliziyweni zihlolwe ngendlela efanayo.
Nantsi indlela esebenza ngayo le nkqubo:
1. Ukulungiselela: Uza kulala etafileni yokuhlolwa. Emva koko uza kunikwa isithomalalisi sokukunceda uphumle. Uza kuba sengqondweni uninzi lwexesha, kodwa uza kukhululeka kakhulu. Awuyi kuva ntlungu.
2. Ukucoca nokuvala iintlungu: Indawo apho kuza kufakwa khona i-catheter (ngokuqhelekileyo i-groin) icocwa kakuhle ngesisombululo se-antiseptic. Emva koko, kufakwa i-anesthetic ukuze kuvale iintlungu kwindawo leyo.
3. Ukufaka i-catheter:Ugqirha ngoku uza kwenza umngxuma omncinci kwindawo engenanto aze afake isikhongozeli seplastiki kuyo. Oku kuya kwenza kube lula ukufaka i-catheter kwimithambo yegazi. I-catheter ye-IVUS iya kufakwa ngayo ize ikhokelwe kumthambo ukuze ihlolwe.
4. Ukuthatha imifanekiso: Nje ukuba i-catheter ibekwe endaweni yayo, i-ultrasound probe ekwincam iyavulwa ukuze ithathe imifanekiso yangaphakathi yomthambo wegazi. Ugqirha ukwenza oku ngelixa ejonge isikrini sekhompyutha.
5. Ukugqiba: Emva kokuba yonke imifanekiso efunekayo ifunyenwe, ugqirha ususa ngononophelo i-catheter kunye ne-sheath. Ekubeni i-incision incinci kakhulu, akusoloko kufuneke ukuba kuthungwe. Kufakwa ibhandeji elicocekileyo kwindawo yotyando ukuthintela usulelo.
Iziphumo kunye nokuBuyisa
Enye into entle ngolu vavanyo kukuba iziphumo zifumaneka ngexesha langempela. Nangona kunjalo, ugqirha uza kukuchazela oku emva kokuba uvavanyo luphelile kwaye iziphumo zeziyobisi ozinikiweyo ziphelile. Usenokukwazi ukubona iziphumo ngelixa usesegumbini lokuchacha.
Ngokuphathelele ukuchacha, ukuba ubuvavanywe nge-IVUS kuphela, ungaya ekhaya ngaloo mini inye. Nangona kunjalo, ukuba ubukwenzile oku kunye novavanyo lwe-cardiac catheterization, kunokufuneka uhlale esibhedlele ubusuku bonke. Ugqirha wakho uza kukwazisa ngale nto kwangaphambili.
