Kuziba kw'imitsi y'umutima wawe ni ikibazo gikomeye kingana iki? (Fractional Flow Reserve - FFR) Reka tubisuzume dukoresheje ikizamini!

Ese ukeka ko ufite indwara y'umutima? Cyangwa muganga wawe yavuze ko imitsi yawe y'umutima yazibye? Ushobora kuba warumvise iki kizamini cyitwa Fractional Flow Reserve, cyangwa FFR mu magambo ahinnye. Nubwo gishobora kumvikana nk'izina rigoye, ni ikizamini cy'ingenzi cyane. Reka tubiganireho uyu munsi mu rurimi rw'igisinhala rworoshye kandi rwumvikana.

Amafaranga yo kubika ingano y'umuvuduko w'amazi (Fractional Flow Reserve - FFR) ni iki?

Mu magambo make, (FFR) ni uburyo bwo gupima neza ubukana bwa stenosis, ni ukuvuga uburyo ibangamira amaraso atembera neza, niba hari ahantu runaka mu mitsi y’umutima itanga amaraso mu mutima wawe. Tekereza ko iyo umuyoboro w’amazi ufunze, umuvuduko n’umuvuduko w’amazi biragabanuka, si byo? Mu buryo nk’ubwo, iyo imitsi y’umutima ifunze, umuvuduko w’amaraso anyuramo uragabanuka. Icyo iki kizamini (FFR) gikora ni ugupima itandukaniro ry’umuvuduko no kumenya neza ingano y’umuvuduko.

Ubusanzwe abaganga bakora iki kizamini (FFR) mu gihe cyo gupima umutima hakoreshejwe catheter cyangwa coronary angiogram. Ibisubizo by'iki kizamini bifasha kumenya ubwoko bw'ubuvuzi ugomba guhabwa (urugero, niba ugomba gufata imiti wenyine cyangwa angioplasty na stent). Iki ni ikizamini cy'ingenzi cyane gishobora kugufasha gufata ibyemezo by'ingenzi.

Ni ryari ikizamini cya FFR gikenewe?

Si buri wese uzakenera gukora iki kizamini. Muganga azafata icyemezo cyo gukora iki kizamini (FFR) mu bihe bimwe na bimwe byihariye.

• Niba isuzuma ry’imitsi y’umutima rigaragaza ko hagati ya 50% na 70% by’umurambararo w’imitsi ifunganye (stenosis), iki kizamini (FFR) gishobora kugaragaza neza uburyo iyo mitsi ifunganye mu by’ukuri ibuza amaraso gutembera.
• Hari igihe, nubwo haba hari uruziga rukomeye rwa 90% by'imitsi ifungana, iki kizamini gikorwa kugira ngo hamenyekane neza ubukana bwayo.

Ariko, niba imitsi yawe ifunganye iri munsi ya 30% cyangwa irenga cyane 70%, iki kizamini (FFR) ubusanzwe si ngombwa. Kuko niba ifunganye ari nto cyane (munsi ya 30%), ubuvuzi (nk'ubugororangingo) ntabwo buzaba ngombwa. Niba ifunganye ari nini cyane (irenga 70%), ubuvuzi burakenewe rwose. Icyo (FFR) ikora ni ukugufasha gufata icyemezo gikwiye muri ibyo bihe biri hagati.

Icy'ingenzi: Niba warigeze gukorerwa angioplasty no gushyirwamo stent mu mitsi yawe, iki kizamini (FFR) gishobora no gufasha kumenya niba umutima wawe ushobora kurwara indwara ikomeye mu gihe kizaza.

Ese hari ingaruka mbi kuri iki kizamini (FFR)?

Nk’uko bigenda kuri buri kizamini cyo kwa muganga, hari utuntu duto two kuzirikana.

• Hari igihe igisubizo gisanzwe gishobora kubaho. Ibi bivuze ko mu by'ukuri hari ikibazo, ariko ikizamini gishobora kutagitahura. Impamvu imwe ishobora gutuma ibi bibaho ni uko imitsi mito cyane y'amaraso (coronary arterioles) idakira neza imiti itangwa mu gihe cy'ikizamini kugira ngo imitsi yawe y'amaraso yaguke.
• Nanone, uburebure bw'agace kari mu mutsi bugira ingaruka ku gaciro ka FFR.

Kubera ko umuganga wawe azi neza ibyo bintu byose, azafata ibyemezo nyuma yo gusuzuma ibi bintu byose.

(iFR) na (FFR) ni iki? Itandukaniro riri hagati y'ibyo byombi ni irihe?

Ushobora kuba warumvise ikintu cyitwa (iFR). (iFR) gisobanura (igipimo cy’umuvuduko w’amaraso udashobora guhindagurika). Byombi (FFR) na (iFR) ni ibizamini bipima ubukana bw’imitsi y’umutima. Ariko hari itandukaniro rito.

• Mu gihe cyo gupima (FFR): Hatangwa umuti wihariye, nka adenosine (Adenocard® cyangwa Adenoscan®), kugira ngo wongere imiyoboro y'amaraso no kongera amaraso atembera.
• Mu kizamini cya (iFR): Hatabayeho gukoresha umuti nk'uwo, umuvuduko upimirwa mu gihe runaka mu gihe umutima uhagaze.

Nubwo intego ya byombi ari imwe, hari itandukaniro rito mu buryo bikorwamo. Muganga wawe ni we uzaguhitiramo ikikubereye.

Ni nde ukora ikizamini cya (FFR)?

Iki ni ikizamini cy’ubuvuzi cyihariye. Ikizamini cya (FFR) gikorwa n’inzobere mu by’umutima , ufite amahugurwa yihariye kuri ibi.

Ikizamini cya (FFR) gikora gite?

Ibi bishobora gusa nkaho ari uburyo bworoshye, ariko bisaba uburyo bugoye. Umuvuduko w'amaraso upimwa haba kure y'aho imitsi y'umutima ifunganye ndetse no hafi yayo . Ni ukuvuga ko umuvuduko upimwa mbere na nyuma yo kuziba. Igipimo kiri hagati y'ibi bipimo bibiri by'umuvuduko cyitwa fractional fraction (FFR). Ibi nibyo biduha igitekerezo cy'uburyo amaraso atembera nabi.

Ni gute nakwitegura ikizamini cya (FFR)?

Ibi ni nko kwitegura kubagwa gato. Muganga wawe azagusobanurira ibisobanuro birambuye, ariko ibi ni ibintu rusange uzakenera gukora:

• Muganga wawe ashobora kugusaba guhagarika gufata imiti imwe n'imwe, cyane cyane imiti igabanya amaraso , iminsi mike mbere yo gupimwa.
• Ntukarye cyangwa ngo unywe ikintu icyo ari cyo cyose nyuma ya saa sita z'ijoro mbere y'uko upimwa (NPO - ntukanywe ikintu icyo ari cyo cyose).
• Kubera ko uzahabwa ikinya cyangwa umuti woroshye wo kugabanya ububabare muri iki kizamini, uzakenera umuntu uzagutwara akagutwara mu rugo nyuma yo gupimwa. Ntuzashobora gutwara imodoka ubwawe.

Ni iki wakwitega ku munsi w'ikizamini (FFR)?

Ikizamini ubwacyo gikunze kumara igihe kitarenze isaha . Ariko, iyo muganga asuzumye FFR yawe ako kanya agafata icyemezo cyo gukora angioplasty cyangwa stent, bizatwara igihe cy'inyongera. Kubwibyo, ni byiza kubaza muganga wawe mbere y'igihe uzakenera kumara mu bitaro, harimo n'igihe cyo kwitegura no kuruhuka nyuma y'ikizamini.

Ni iki kibaho mu gihe cy'ikizamini cya (FFR)?

Noneho reka turebe ikizaba mu isuzuma. Nubwo izi ntambwe zishobora gusa n'izigoye, itsinda ry'abaganga rizakwitaho neza.

2. Gushyiramo urushinge: Hanyuma, urushinge ruto rushyirwa mu mutsi unyuze aho rwatobowe.

3. Gushyiramo katheteri: Binyuze muri uku gukata, icyuma gito cyane, kirekire kimeze nk'umuyoboro (catheteri) gica mu mitsi yawe y'amaraso kikagera mu mitsi y'umutima wawe.

4. Kureba inzira: Uburyo bwihariye (bwa X-ray) bwitwa fluoroscopy bukoreshwa mu gusuzuma kuri ecran kugira ngo harebwe niba catheter igiye ahantu heza.

5. Uduce duto two gutandukanya ibara: Hanyuma, irangi ryihariye (contrast media) rishyirwa mu mitsi y'umutima wawe binyuze muri iyi catheter. Hanyuma imitsi igaragara neza kuri X-ray.

6. Ikizamini cyo gufungana kw'imitsi: Iki gikoreshwa mu kugenzura niba hari aho imitsi y'umutima wawe yazibye.

7. Kureba uko amaraso atembera: Hari igihe icyuma gito gikoresha ultrasound gifatanye n'intambwe y'iyi catheter gishobora gukoreshwa mu kureba uko amaraso atembera mu miyoboro y'amaraso.

8. Gutanga imiti: Mbere yuko insinga y'umuvuduko ishyirwa mu gace kafunze, imiti nka heparin (yo gukumira kuvura kw'amaraso) na nitroglycerin (yo kwagura imiyoboro y'amaraso) (Nitronal® cyangwa Tridil®) iratangwa.

9. Gupima umuvuduko: Noneho hagiye kubaho akazi nyako. Insinga yihariye (umuvuduko) inyuzwa mu gace kafunzwe, kandi ibikoresho bipima umuvuduko w'amaraso biriho bipima mbere na nyuma yuko imitsi ifunzwe. Kugira ngo ibi bipime neza, amaraso atembera neza mu gihe amaraso atembera neza. Kuri ibyo, hatangwa umuti (adenosine) cyangwa (papaverine) kugira ngo wongere umuvuduko w'amaraso yawe by'agateganyo.

10. Kuvura (nibiba ngombwa): Iyo kuziba kw'imitsi bifatwa nk'ibikomeye hashingiwe ku gipimo cya FFR, angioplasty (kwagura imitsi n'ibaluni) ishobora gukorwa aho ngaho, kandi stent (umuyoboro muto umeze nk'urushundura) ishobora gushyirwaho kugira ngo hirindwe kuziba kw'imitsi.

11. Kongera gupimwa: Nyuma yo gushyirwaho stent, agaciro ka FFR kongera gusuzumwa kugira ngo hemezwe niba uburyo bwo kuvura bwagenze neza.

12. Kurangiza: Amaherezo, catheter n'insinga birakurwaho, aho bapfumuye hagafatwa umwanya, hanyuma hagashyirwa plaster.

Ni iki wakwitega nyuma y'ikizamini cya (FFR)?

Abantu benshi ntibagira ububabare bukabije nyuma y'iki kizamini (FFR), kandi ingorane ni nke cyane.

• Iyo ukoze ikizamini gusa, ubusanzwe ushobora gutaha mu masaha make.
• Ariko, niba warakorewe isuzuma rya angioplasty hanyuma ugashyirwamo stent nyuma ya FFR, ushobora kurara mu bitaro muri iryo joro ukurikiranwe na muganga.

Ni izihe ngaruka mbi zo gupimwa (FFR)?

Nkuko bigenda kuri buri buryo bwose bwo kwa muganga, hari abantu bashobora kumva batameze neza.

• Ushobora kugira ububabare mu gituza cyangwa kugorwa no guhumeka nyuma y'umunota umwe uhawe umuti wa adenosine (waba unyuze mu muyoboro wa IV cyangwa ukajya mu mitsi yo mu mutima wawe).Ibi ni ibisanzwe, ntugire ikibazo. Bivuze ko amaraso yawe atembera neza, bivuze ko ari cyo gihe cyo gupima FFR yawe. Ubu burwayi buzashira vuba.
• (Papaverine) ishobora gutera umutima utari mwiza cyane (hafi 1% by'abantu), ariko ibi bikunze kurangira nyuma y'igihe runaka.
• Ni ngombwa kwibuka ko kubera ko iki kizamini (FFR) gikorerwa hakoreshejwe catheter y'umutima, hari ingaruka zimwe na zimwe zijyanye na cyo (urugero: kuva amaraso, kwandura, allergie ku buryo bwo kugabanya isura y'umubiri). Ariko, ibi ni gake cyane.

Agaciro ka (FFR) kabarwa gute?

Ibi ni nk'uburyo bwo gukoresha imibare. Muganga agabanya umuvuduko uri mu mitsi yawe y'umutima ku ruhande rw'aho ifunga (distal - Pd) n'umuvuduko uri ku ruhande rw'aho ifunga (proximal - Pa).

Mu magambo make, FFR = Pd / Pa .

Ibi bipimo by'umuvuduko bifatwa na muganga akoresheje ibikoresho byihariye mu gihe cyo gushyiramo katheta y'umutima.

Ibisubizo bimeze bite? Bitubwira iki?

Uzabona umubare ufite ahantu hagenwe n'ibice by'inyuma.

• Igipimo gisanzwe cya FFR kiri hagati ya 0.94 na 1.0. Iyo iki gipimo kigeze kuri iyo ngingo, bivuze ko nta mbogamizi ikomeye igaragara ku gutembera kw'amaraso mu mitsi.
• Niba agaciro ka FFR muri rusange kari munsi ya 0.80, bivuze ko kuziba kw'amaraso ari ko gutera kuziba kw'amaraso cyane, bityo hakaba hakenewe ubuvuzi (akenshi na angioplasty na stent).
• Urugero, niba FFR yawe ari 0.75, bivuze ko umuvuduko w'amaraso yawe wagabanutseho 25% bitewe no kugabanuka kw'imitsi y'umutima (1.00 - 0.75 = 0.25, cyangwa 25%).
• Niba agaciro ka FFR kerekana ko kuziba kw'imitsi kudakabije, ntabwo ari ngombwa gukora angioplasty no gusiga stent. Bishobora kuvurwa n'imiti gusa. Ibi bishobora gufasha kwirinda kubagwa bitari ngombwa.

Ni ryari nzamenya ibisubizo by'ikizamini cya (FFR)?

Iki ni cyo kintu cyiza kurusha ibindi. Muganga azakwereka agaciro ka FFR ku gikoresho cye akimara gupima umuvuduko w'amaraso yawe. Bityo, haba mu gihe cyo gupima cyangwa nyuma yuko kirangiye, muganga azakubwira ibisubizo n'icyo gukora nyuma yaho.

Ni ryari ugomba kuvugana na muganga? (Nyuma yo gusuzumwa)

Iyo ugiye mu rugo nyuma yo gupimwa, ugomba guhita ubimenyesha muganga wawe cyangwa ibitaro bikwegereye niba ufite kimwe cyangwa byinshi muri ibi bimenyetso:

• Kubabara mu gituza (cyane cyane ububabare bushya, bukomeye, cyangwa budashira iyo umuntu aruhutse)
• Guhumeka bigoranye
• Umuriro (ubushyuhe bw'umubiri buri hejuru)
• Ububabare, kubyimba, gutukura, cyangwa amabyi aho umuntu yagera
• Kumva umeze nk'uzunguza cyangwa unaniwe
• Umutima utari umeze neza cyangwa gutera cyane

Ntukirengagize ibi bimenyetso.

Amaherezo, ibuka

Iki kizamini (Fractional Flow Reserve - FFR) ni ikizamini cy'indwara y'imitsi y'umutima.Uburyo bugezweho kandi bunoze buzafasha cyane umuganga guhitamo uburyo bwiza bwo kuvura. Abakozi bo kwa muganga bazakora ibishoboka byose kugira ngo ugire ubwisanzure bushoboka mu gihe cyo gusuzumwa. Niba hari ikintu udasobanukiwe cyangwa niba ufite ubwoba, banza ubaze umuganga cyangwa umuforomo. Ni uburenganzira bwawe.

Ni byiza kwitegura mu mutwe ibyo, kuko ushobora gukenera gushyirwaho angioplasty cyangwa stent nyuma yo gusuzuma FFR yawe. Wibuke ko byose bikorwa kugira ngo urinde ubuzima bw'umutima wawe.
