Mwoyo intravascular ultrasound

Intravascular ultrasound (IVUS) ndeye bvunzo yekuongorora. Muedzo uyu unoshandisa mafungu ezwi kuona mukati memidzi yeropa. Izvo zvinobatsira pakuongorora iyo coronary artery iyo inopa moyo.

Chidzitiro chidiki che ultrasound chakabatanidzwa kumusoro kwetepu nhete. Iyi chubhu inonzi kateti. Iyo catheter inoiswa mune tsinga munzvimbo yako yekugomera uye ndokusimudzira kumusoro kumoyo. Izvo zvakasiyana neyakajairika duplex ultrasound. Duplex ultrasound inoitwa kubva kunze kwemuviri wako nekuisa iyo transducer paganda.

Komputa inoyera maratidziro anoita masaisai eropa, uye inoshandura mafungu ezwi kuita mifananidzo. IVUS inopa mupi wezvehutano kutarisisa ako coronary arteri kubva mukati-kunze.

IVUS inowanzoitwa nguva dzose mukati mekuita. Zvikonzero nei zvingaitwe zvinosanganisira:

• Kuwana ruzivo nezve moyo kana mitsipa yeropa kana kuona kana uchida kuvhiyiwa moyo
• Kurapa mamwe marudzi emamiriro ezvinhu emoyo

Angiography inopa kutarisisa kwakawanda kune coronary arteri. Zvisinei, haigone kuratidza madziro etsinga. Mifananidzo yeVIV inoratidza arteri masvingo uye inogona kuburitsa cholesterol nemafuta ekuisa (mabheti). Kuvaka kwezvinhu izvi kunogona kuwedzera njodzi yako yekurwadziwa kwemoyo.

IVUS yakabatsira vanopa rubatsiro kuti vanzwisise kuti stents inovhara sei. Izvi zvinonzi stent restenosis.

IVUS inowanzoitwa kuti ive nechokwadi chekuti stent yakanyatsoiswa panguva yeangoploplasty. Izvo zvinogona zvakare kuitwa kuti uone panofanira kuiswa stent.

IVUS inogona zvakare kushandiswa ku:

• Wona iyo aorta uye chimiro chemadziro etsinga, ayo anogona kuratidza plaque buildup
• Tsvaga kuti ndeupi muropa weropa unobatanidzwa mune aortic dissection

Pane njodzi diki yezvinetso neangioplasty uye catheterization yemoyo. Nekudaro, bvunzo dzakachengeteka kwazvo kana dzikaitwa nechikwata chine ruzivo. IVUS inowedzera imwe njodzi yekuwedzera.

Ngozi dzeanesthesia uye kuvhiyiwa kazhinji ndezvi:

• Zviitiko kumishonga
• Matambudziko ekufema
• Kubuda ropa, kuwanda kweropa
• Utachiona

Dzimwe njodzi dzinosanganisira:

• Kukuvadza kune vharafu yemoyo kana ropa reropa
• Kumira kurova kwemoyo
• Kusajairika kurova kwemoyo (arrhythmia)
• Itsvo kutadza (yakanyanya njodzi kune vanhu vatove nematambudziko eitsvo kana chirwere cheshuga)
• Stroke (izvi hazviwanzo)

Mushure mekuyedzwa, iyo catheter inobviswa zvachose. Bhandeji rinoiswa munzvimbo iyi. Iwe unozobvunzwa kurara wakarara kumusana kwako nekumanikidzwa panzvimbo yako yekugomera kwemaawa mashoma mushure mekuyedzwa kudzivirira kubuda kweropa.

Kana IVUS yakaitwa panguva:

• Catheterization yemwoyo: Iwe uchagara muchipatara kwemaawa matatu kusvika matanhatu.
• Angioplasty: Iwe uchagara muchipatara kwemaawa gumi nemaviri kusvika makumi maviri nemana.

IVUS haina kuwedzera kune iyo nguva yaunofanira kugara muchipatara.
