Duplex ultrasound

Duplex ultrasound bụ ule iji hụ otú ọbara si agagharị na akwara gị.

A duplex ultrasound jikọtara:

• Omenala ultrasound: Nke a na-eji ebili mmiri nke na-agbapụta arịa ọbara iji mepụta foto.
• Doppler ultrasound: Nke a na-ede ụda ebili mmiri na-egosipụta ihe na-agagharị, dị ka ọbara, iji tụọ ọsọ ha na akụkụ ndị ọzọ nke otu ha si asọ.

E nwere ụdị ule duplex ultrasound dị iche iche. Fọdụ gụnyere:

• Ultrasound na venous duplex ultrasound nke afọ. Ule a na-enyocha arịa ọbara na nrugharị ọbara n'ime mpaghara afọ.
• Carotid duplex ultrasound na-eleba akwara carotid na olu.
• Duplex ultrasound nke nsọtụ na-ele anya na ogwe aka ma ọ bụ ụkwụ.
• Renal duplex ultrasound na-enyocha akụrụ na akwara ọbara ha.

Ikwesiri iyi uwe gwọọ gị. Ga-edina ala na tebụl, onye ọrụ ntanetị ga-agbasakwa gel n'elu ebe a na-anwale. Gel na-enyere ụda ụda aka ịbanye na anụ ahụ gị.

A na-eme ka otu mkpanaka, nke a na-akpọ transducer, gafere ebe a na-anwale. Nke a na-ezipụ ụda ebili mmiri. Kọmputa na-atụle etu ụda ụda si ada ụda, wee gbanwee ụda mmiri na foto. Doppler na-emepụta ụda "na-agbanwe", nke bụ ụda ọbara gị na-agagharị na akwara na akwara.

Ikwesiri ịnọ otu ebe n’ule ahụ. Enwere ike ịgwa gị ka ị dina n'ọnọdụ dị iche iche, ma ọ bụ were iku ume miri emi ma jigide ya.

Mgbe ụfọdụ, n'oge duplex ultrasound nke ụkwụ, onye na-ahụ maka ahụike nwere ike gbakọọ mkpịsị ụkwụ nkwonkwo ụkwụ (ABI). Ikwesiri iyi akwa aka na aka gị na ụkwụ gị maka ule a.

A na-enweta nọmba ABI site na ịkekọrịta ọbara mgbali na nkwonkwo ụkwụ site na mgbatị ọbara na ogwe aka. Uru nke 0.9 ma ọ bụ karịa bụ nkịtị.

Ọtụtụ mgbe, enweghị nkwadebe maka ule a.

Ọ bụrụ na ị na-enwe ultrasound nke mpaghara afọ gị, enwere ike ịgwa gị ka ị ghara iri nri ma ọ bụ drinkụọ mgbe etiti abalị. Gwa onye na-eme nyocha nke ultrasound ma ọ bụrụ na ị na-a anyụ ọgwụ ọ bụla, dị ka ihe na-egbu ọbara. Ihe ndị a nwere ike ịmetụta nsonaazụ nke ule ahụ.

You nwere ike ịnwe nrụgide ụfọdụ ka wand ahụ na-ebugharị n'ahụ, mana enweghi nkasi obi ọtụtụ oge.

Duplex ultrasound nwere ike igosi etu ọbara si aga n'ọtụtụ akụkụ ahụ. O nwekwara ike ịkọ obosara nke arịa ọbara ma kpughee mgbochi ọ bụla. Ule a bụ nhọrọ na-adịghị emerụ ahụ karịa arteriography na venography.

Duplex ultrasound nwere ike inyere aka chọpụta ọnọdụ ndị a:

• Akwukwo afọ
• Mgbachi ọbara
• Ọbara ọbara
• Ọrịa Carotid occlusive (Lee: Carotid duplex)
• Renal vaskụla ọrịa
• Mgbanwe dị iche iche
• Erughị ala Venus

Enwere ike iji ihe eji eme ihe na ịwa ahụ. Nke a gosiri etu akụrụ ọhụrụ si arụ ọrụ.

Nsonaazụ dị mma bụ ịgbanye ọbara site na veins na akwara. E nwere ọbara mgbali nkịtị na ọ nweghị ihe ịrịba ama nke ibelata ma ọ bụ mgbochi nke arịa ọbara.

Nsonaazụ na-adịghị mma na-adabere na mpaghara a kapịrị ọnụ na-enyocha. Nsonaazụ na-adịghị mma nwere ike ịbụ n'ihi mkpụkọ ọbara ma ọ bụ ihe nrụpụta n'ime arịa ọbara.

Enweghị nsogbu ọ bụla.

Ise siga nwere ike ịgbanwe nsonaazụ nke ultrasound nke aka na ụkwụ. Nke a na - eme n’ihi na nikotin nwere ike ime ka akwara ghara ịda mbà (constrict).
