Obi ultrasound intravascular nke obi

Intravascular ultrasound (IVUS) bụ ule nyocha. Ule a na-eji ebili mmiri iji hụ n'ime arịa ọbara. Ọ bara uru maka ịtụle akwara akwara na-enye obi.

A na-etinye obere mkpịsị ultrasound n'elu nke tube dị gịrịgịrị. A na-akpọ ọkpọkọ a catheter. A na-etinyere catheter ahụ n'ime akwara ọbara dị n'akụkụ oke gị wee kwaga na obi. Ọ bụ ihe dị iche na ot duplex ultrasound. A na-eme ultrasound Duplex site na mpụga ahụ gị site na ịtụkwasị transducer na akpụkpọ ahụ.

Kọmputa na-atụle etu ụda ụda si egosipụta arịa ọbara, wee gbanwee ụda mmiri na foto. IVUS na-enye ndị na-ahụ maka ahụike ka ha lebara akwara akwara gị anya site n’ime pụta.

IVUS fọrọ nke nta ka ọ bụrụ na a na-eme ya mgbe niile n'oge usoro. Ihe mere enwere ike ime ya gụnyere:

• Inweta ihe ọmụma banyere obi ma ọ bụ arịa ọbara ya ma ọ bụ iji chọpụta ma ịchọrọ ịwa obi
• Na-emeso ụfọdụ ụdị ọnọdụ obi

Ihe omuma ihe omimi na-enye nlezianya anya banyere akwara obi. Otú ọ dị, ọ pụghị igosipụta mgbidi nke akwara. Ihe oyiyi IVUS na-egosi mgbidi akwara ma nwee ike ikpughe cholesterol na abụba (ihe mbibi). Mmebe nke nkwụnye ego ndị a nwere ike ime ka ihe egwu gị maka nkụchi obi dịkwuo elu.

IVUS enyerela ndị na-enye ọrụ aka ịghọta etu esi egbochi stents. A na-akpọ nke a stent restenosis.

A na-emekarị IVUS iji jide n'aka na etinyela stent n'ụzọ ziri ezi n'oge angioplasty. Enwere ike ịme ya iji chọpụta ebe ekwesịrị itinye ya.

Enwere ike iji IVUS mee ihe:

• Ele aorta na Ọdịdị nke akwara mgbidi, nke nwere ike na-egosi ihe e dere ede buildup
• Chọta ihe arịa ọbara na-arụ na mgbasa nke aortic

Enwere obere ihe egwu maka nsogbu na angioplasty na cardiac catheterization. Otú ọ dị, ule ndị ahụ dị nchebe ma ọ bụrụ na ndị otu nwere ahụmahụ mere ya. IVUS na-agbakwunye obere ihe egwu.

Ihe ize ndụ nke ọgwụ nchịkwa na ịwa ahụ n'ozuzu ya bụ:

• Mmeghachi omume na ọgwụ
• Nsogbu iku ume
• Ọbara ọgbụgba, mkpụkọ ọbara
• Ofufe Ọrịa

Ihe ize ndụ ndị ọzọ gụnyere:

• Mmebi na valvụ obi ma ọ bụ arịa ọbara
• Obi nkolopu
• Oge ufodu obi (arrhythmia)
• Akụrụ ọdịda (ihe ize ndụ dị elu na ndị nwere nsogbu akụrụ ma ọ bụ ọrịa shuga)
• MKpọnwụ (nke a adịkarịghị)

Mgbe ule ahụ gasịrị, a na-ewepụ catheter ahụ kpamkpam. A na-etinye bandeeji na mpaghara ahụ. A ga-agwa gị ka ị dinara ala n’azụ gị na nrụgide na mpaghara ukwu gị maka awa ole na ole mgbe ule ahụ gachara iji gbochie ọbara ọgbụgba.

Ọ bụrụ na etinyere IVUS n'oge:

• Cardiac catheterization: will ga-anọ n'ụlọ ọgwụ ihe dịka 3 ruo 6 awa.
• Angioplasty: will ga-anọ n'ụlọ ọgwụ maka awa 12 ruo 24.

IVUS anaghị atụkwasị na oge ị ga-anọ n'ụlọ ọgwụ.
