Transcranial Doppler ultrasound

Transcranial doppler ultrasound (TCD) bụ ule nyocha. Ọ na-atụle ọbara na-abanye na n'ime ụbụrụ.

TCD na-eji ebili mmiri iji mepụta onyonyo nke ọbara n'ime ụbụrụ.

Nke a bụ otu esi eme ule ahụ:

• Ga-edina n’azụ gị n’elu tebụl e tinyere n’elu ya, jiri isi gị na olu gị nọrọ ohiri isi. Olu gị agbatịtụ ntakịrị. Ma ọ bụ ịnwere ike ịnọdụ ala n'oche.
• Ndị ọkachamara ahụ na-etinye gel na mmiri na ụlọ nsọ gị na nku anya gị, n'okpuru agba gị, na n'okpuru olu gị. 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. Ugboro a na-ezipụ ebili mmiri. Wavesda ebili mmiri ahụ na-esi n’ahụ́ gị pụọ ma kwatuo n’ebe a na-amụ ihe (n’okwu a, ụbụrụ gị na akwara ọbara).
• Kọmputa na-ele ihe nlere anya nke ụda ụda na-eme mgbe ha laghachi azụ. Ọ na-emepụta ihe osise site na ụda ebili mmiri. Doppler na-emepụta ụda "na-agbanwe", nke bụ ụda ọbara gị na-agagharị na akwara na akwara.
• Nnwale ahụ nwere ike iji 30 nkeji gaa elekere 1 iji wuchaa ya.

Enweghị mkpa pụrụ iche maka ule a. Ikwesighi igbanwe uwe ogwu.

Cheta na:

• Wepu lensụ kọntaktị tupu ule ahụ ma ọ bụrụ na ị yikwasị ha.
• Mechie anya gị mgbe etinyere gel na nku anya gị ka ị ghara isite ya n'anya gị.

Gel nwere ike ịjụ oyi na akpụkpọ gị. Nwere ike ịnwe nrụgide ụfọdụ ka onye ntụgharị ahụ na-ebugharị n'isi na n'olu gị. Nrụgide ahụ ekwesịghị ịkpata ihe mgbu. Nwekwara ike ịnụ ụda "whooshing". Nke a bụ ihe nkịtị.

A na-eme nyocha ahụ iji chọpụta ọnọdụ ndị na-emetụta ọbara na ụbụrụ:

• Na-agbachi ma ọ bụ mgbochi nke akwara na ụbụrụ
• Ọrịa strok ma ọ bụ ọgụ na-adịru nwa oge (TIA ma ọ bụ ministroke)
• Ọbara ọgbụgba dị n'etiti ụbụrụ na anụ ahụ nke na-ekpuchi ụbụrụ (ọbara ọgbụgba subarachnoid)
• Ballooning nke arịa ọbara n'ime ụbụrụ (ụbụrụ ụbụrụ)
• Gbanwee na nrụgide n'ime okpokoro isi (intracranial pressure)
• Ọrịa Sickle cell anaemia, iji chọpụta ihe egwu dị na ọrịa strok

Akụkọ a na-ahụkarị na-egosi nrugharị ọbara nkịtị na ụbụrụ. Enweghị mpempe ma ọ bụ mgbochi n'ime arịa ọbara nke na-eduga na n'ime ụbụrụ.

Nsonaazụ na-adịghị mma pụtara na akwara nwere ike ịlalata ma ọ bụ ihe na-agbanwe agbanwe ọbara na akwara ụbụrụ.

Enweghị nsogbu ọ bụla na ịnwe usoro a.
