Kwenzekani ngaphakathi kwemithambo yegazi yakho? Ake sifunde nge-Intravascular Ultrasound ngendlela elula!

Bheka manje, imithambo yegazi engaphakathi kwemizimba yethu ifana nemigwaqo. Igazi lihamba ngale migwaqo, liletha ukuphila kuzo zonke izingxenye zomzimba wethu. Kodwa-ke, ngezinye izikhathi le migwaqo ingaba nezinkinga ezincane. Ezinye izindawo zingavalwa noma zincishiswe. Esikhathini esidlule, kwakunzima kancane ukunakekela lezi zinto. Kodwa manje, ngokuthuthuka kwesayensi yezokwelapha, sinezindlela ezingabonakala ngaphakathi kwale mithambo yegazi. Enye indlela emangalisayo ibizwa ngokuthi `(Intravascular Ultrasound)`. Ake sixoxe ngalokhu namuhla kalula, ngendlela ongayiqonda.

Kuyini ngempela lokhu (i-Intravascular Ultrasound)?

Kalula nje, le `(Intravascular Ultrasound)` ifana nekhamera encane engafakwa emithanjeni yethu yegazi. Kodwa lena isebenzisa amaza omsindo, hhayi ikhamera. Yebo, uyizwile kahle! Amaza omsindo asetshenziselwa ukuthola izithombe ezicacile zezindonga zangaphakathi zemithambo yegazi kanye nezicubu ezithambile lapho. Cabanga ukuthi kungaba usizo kangakanani ukukwazi ukufaka idivayisi encane bese ubona okwenzekayo ngaphakathi ngokushesha, ngaphandle kokuhlinzwa okukhulu.

Le ndlela isetshenziswa ikakhulukazi ukuhlola imithambo yegazi ezungeze inhliziyo, okungukuthi imithambo yenhliziyo . Ngoba lena yimithambo yegazi eyinhloko ehlinzeka ngegazi enhliziyweni. Kodwa-ke, lokhu akugcini enhliziyweni. Le ndlela (IVUS) ingasetshenziswa futhi ukuhlola eminye imithambo yegazi emzimbeni.

Ibizwa ngamanye amagama, futhi udokotela wakho angase ayibize ngelinye lalawa:

• I-ultrasound ye-Coronary intravascular
• I-ultrasound ye-Endovascular
• I-echocardiography ye-Intravascular

Kungakhathaliseki ukuthi libizwa ngani, lenza into efanayo - ukubheka kahle ngaphakathi kwemithambo yegazi.

Lokhu (IVUS) kusebenza kanjani? Kuyamangalisa, akunjalo?

Manje mhlawumbe uyazibuza, le nto encane ingena kanjani emthanjeni wegazi bese ibona konke lokhu? Lobu ubuchwepheshe obulula kakhulu futhi obuthuthukisiwe kakhulu.

Kulolu vivinyo lwe-`(IVUS)`, odokotela basebenzisa ipayipi elincane kakhulu neliguquguqukayo . Lokhu kubizwa ngokuthi i-`(catheter).` Kolunye uhlangothi lwale `(catheter)` kunamathiselwe i-`(ultrasound probe) encane. Kufana nekhanda lomshini omncane wokuskena.

Okulandelayo, udokotela wenza ukusika okuncane esikhumbeni sakho. Lokhu kuvame ukwenziwa embotsheni . Ukusuka lapho, i-catheter ifakwa kancane kancane emthanjeni wegazi. Bese iqondiswa emthanjeni wegazi ofuna ukuwuhlola.

Uma isifikile lapho, i-ultrasound probe ekwi-catheter ikhipha amaza omsindo avame kakhulu. Lawa maza omsindo agxuma odongeni lwemithambo yegazi bese ebuyela emuva, njengokuzwakala kwemisindo. Amaza omsindo abuyayo ahlaziywa yikhompyutha bese eguqulwa abe izithombe zesikhathi sangempela. Cabanga ubuka i-movie ye-3D ngaphakathi kwemithambo yegazi! Lokhu kuvumela odokotela ukuthi babone hhayi kuphela ingaphakathi lemithambo yegazi, kodwa futhi nobukhulu bezindonga zayo nokuthi ngabe kukhona yini ama-deposit.

Yiziphi izinzuzo zokuhlolwa kwe-IVUS kuwe?

Lokhu akulona nje ukuhlolwa. Kuyinto enganezela inani elikhulu empilweni yakho. Lokhu kuhlolwa "(IVUS)" kuwusizo olukhulu, ikakhulukazi uma odokotela besola ukuthi imithambo yegazi yakho inciphile noma ivalekile .

Lokhu kuhlolwa kungasiza ekuphatheni ezinye izimo ezisongela impilo , njenge:

• Ukuhlaselwa yinhliziyo: Lokhu kwenzeka lapho imithambo yegazi ethwala igazi eya enhliziyweni ivaleka. I-IVUS ingabonisa ukuthi ukuvaleka kukhulu kangakanani.
• I-Pulmonary embolism: Ukugoba kwegazi emithanjeni yegazi yamaphaphu.
• Isifo sohlangothi: Kungabangelwa inkinga ngemithambo yegazi ehambisa igazi ebuchosheni.

Ngaphezu kwalokho, ukuhlolwa kwe-IVUS kusiza nodokotela:

• Hlola ubukhali bokwakheka kwe-plaque, okuyiqoqo lamafutha ngaphakathi kwemithambo yegazi. Yilokhu odokotela abakubiza ngokuthi i-atherosclerosis. Kubuye kubheke ukuthi kungenzeka kangakanani ukuthi imithambo yegazi ivaleke.
• Lokhu kuzokusiza ukuthi unqume ukuthi udinga ukwelashwa okwengeziwe, njengokuhlinzwa kwe-coronary artery bypass .
• Hlela futhi unikeze ukwelashwa ngokunembile. Ngezinye izikhathi, uma umthambo wegazi uvalekile, kungadingeka kufakwe idivayisi encane efana ne-mesh ebizwa ngokuthi i-stent ukuze ihlale ivulekile. I-IVUS iyasiza ekuqinisekiseni ukuthi i-stent ibekwe kahle, ukuthi kufanele ibe nkulu kangakanani, nokuthi kufanele ifakwe kuphi.

Cabanga nje, lokhu kufana nokuthola isithiyo emgwaqweni, wazi kahle ukuthi sikhulu kangakanani, nokuthi yini okudingeka yenziwe ngakho.

Ngingazi kanjani ukuthi lokhu (IVUS) kuyangifanele?

Akuwona wonke umuntu odinga lokhu kuhlolwa. Udokotela wakho uzonquma ukuthi uyakudinga yini. Kodwa-ke, uma unezinye zezimpawu ezilandelayo, noma usengozini enkulu yokuthola lezi zimo, udokotela wakho angancoma ukuhlolwa kwe-IVUS:

• I-Aortic aneurysm: Ukuqina nokuqina kodonga lomthambo wegazi omkhulu emzimbeni.
• Amahlule egazi: Amahlule egazi akheka ngaphakathi kwemithambo yegazi.
• Isifo semithambo ye-carotid:Amafutha afakwa emithanjeni eyinhloko entanyeni ethwala igazi liye ebuchosheni.
• Isifo semithambo yenhliziyo: Ukuncipha noma ukuvaleka kwemithambo yegazi ehambisa igazi enhliziyweni.
• I-Deep vein thrombosis (DVT): Amahlule egazi emithanjeni ejulile, ikakhulukazi emilenzeni.
• Isifo semithambo yegazi engaphandle (i-PAD): Ukuncipha kwemithambo yegazi ezingalweni ikakhulukazi emilenzeni.
• I-pulmonary artery stenosis: Ukuncipha komthambo ozalwa nawo noma otholakalayo othwala igazi emaphashini.

Uma unalezi zimo, i-IVUS ingaba usizo olukhulu ekuxilongeni lesi sifo ngokunembile nasekuhleleni ukwelashwa.

Uyini umehluko phakathi kwe-(IVUS) kanye ne-(Angiography)?

Kungenzeka ukuthi uke wezwa nangokuhlolwa okubizwa ngokuthi "i-Angiography." Kuthatha nezithombe zangaphakathi kwemithambo yegazi. Kodwa kukhona umehluko phakathi kwalokhu okubili.

• I-Angiography: Lokhu kusebenzisa ama-X-ray . Kukhiqiza izithombe zesithunzi zemithambo yegazi ezinezilinganiso ezimbili. Kufana nokubuka ingaphandle lomthambo wegazi bese uthola umbono ocacile wokuthi ubukeka kanjani.
• (IVUS): Njengoba kushiwo ngaphambili, lokhu kusebenzisa amaza omsindo . Lokhu kukhiqiza izithombe ezinqamula izigaba. Njengoba nje usika isinkwa sibe yizicucu, ungabona ngokucacile izingqimba zangaphakathi zomthambo wegazi, ukujiya kodonga, kanye nendlela amafutha afakwa ngayo.

Kalula nje, nakuba i-angiography inikeza okuthile okufana "nemephu" yemithambo yegazi, i-IVUS inikeza ulwazi oluningiliziwe mayelana nengaphakathi lemithambo yegazi kuleyo "mephu" kanye nesimo sayo.

Kwenziwa kanjani ukuhlolwa (kwe-IVUS)?

Indlela okwenziwa ngayo lokhu ingase ihluke kancane, kuye ngokuthi yimuphi umthambo wegazi ohlolwayo.

• Uma uhlola imithambo yenhliziyo: Lokhu kuhlolwa kwe-IVUS kuvame ukwenziwa kanye nolunye ukuhlolwa okubizwa ngokuthi i-cardiac catheterization . Lokhu kuhlolwa kwenhliziyo kuhlola izinto ezifana nokusebenza kwenhliziyo kanye nomfutho wegazi. Ngakho-ke, ngokwenza kokubili ukuhlolwa ngesikhathi esisodwa, odokotela bangathola ulwazi olwengeziwe mayelana nempilo yenhliziyo ngesikhathi esisodwa.
• Uma kuhlolwa eminye imithambo yegazi engahlobene nenhliziyo: isibonelo, ukuhlola amahlule egazi emithanjeni yemilenze, noma ukuhlola i-PAD emithanjeni yemilenze, ukuhlolwa kwe-IVUS kwenziwa kodwa, okungukuthi, njengenqubo ezimele.

Ubani owenza lolu vivinyo (i-IVUS)?

Lokhu akulona ukuhlolwa okwenziwa udokotela ojwayelekile. Kwenziwa ngabantu abaqeqeshwe ngokukhethekile ngale njongo.
