I-biopsy yezinzwa

I-nerve biopsy ukususwa kocezu oluncane lwe-nerve ukuze kuhlolwe.

I-nerve biopsy ivame ukwenziwa kunzwa eseqakaleni, ingalo, noma ubambo.

Umhlinzeki wezokunakekelwa kwezempilo usebenzisa umuthi wokundikaza indawo ngaphambi kwenqubo. Udokotela wenza ukusika okuncane futhi asuse ucezu lwenzwa. Ukusikwa kube sekuvalwa bese kufakwa ibhandishi kuso. Isampula lezinzwa lithunyelwa elebhu, lapho lihlolwa khona ngesibonakhulu.

Landela imiyalo yomhlinzeki wakho yokuthi ungayilungiselela kanjani inqubo.

Lapho umuthi obandayo (i-anesthetic yendawo) ujojowe, uzozwa ukubhoboza nokuhlaba okuncane. Isayithi le-biopsy lingaba buhlungu izinsuku ezimbalwa ngemuva kokuhlolwa.

I-biopsy ye-nerve ingenziwa ukusiza ukuxilonga:

• Ukwehla kwe-axon (ukubhujiswa kwengxenye ye-axon yeseli lezinzwa)
• Ukulimala kwezinzwa ezincane
• Ukudonswa kwesikhumba (ukubhujiswa kwezingxenye zomgodi we-myelin ohlanganisa imizwa)
• Izimo zezinzwa ezivuthayo (i-neuropathies)

Imibandela okungenziwa ngayo ukuhlolwa ifaka noma yikuphi kokulandelayo:

• I-neuropathy yotshwala (ukulimala kwezinzwa eziphuza ngokweqile utshwala)
• Ukungasebenzi kwemizwa ye-Axillary (ukulimala kwethambo lehlombe eliholela ekulahlekelweni kokuhamba noma ukuzwa ehlombe)
• I-brachial plexopathy (ukulimala kwe-plexus ye-brachial, indawo ohlangothini ngalunye lwentamo lapho izimpande zezinzwa ezisuka entanjeni yomgogodla zihlukana zibe izinzwa zengalo ngayinye)
• Isifo seCharcot-Marie-Tooth (iqembu elinefa lokuphazamiseka okuthinta izinzwa ezingaphandle kobuchopho nomgogodla)
• Ukungasebenzi kahle kwe-peroneal nerve (ukulimala kwethambo le-peroneal eliholela ekulahlekelweni kokuhamba noma ukuzwa onyaweni nasemlenzeni)
• Ukukhubazeka kwezinzwa eziphakathi nendawo (ukulimala kwethambo eliphakathi nendawo okuholela ekulahlekelweni ukunyakaza noma ukuzwa ezandleni)
• I-mononeuritis multiplex (ukuphazamiseka okubandakanya ukulimala okungenani izindawo ezimbili zezinzwa)
• I-Necrotizing vasculitis (iqembu lezinkinga ezibandakanya ukuvuvukala kwezindonga zomthambo wegazi)
• I-Neurosarcoidosis (inkinga ye-sarcoidosis, lapho ukuvuvukala kwenzeka khona ebuchosheni, emgogodleni nakwezinye izindawo zesistimu yezinzwa)
• Ukungasebenzi kahle kwe-radial nerve (ukulimala kwethambo le-radial okuholela ekulahlekelweni kokunyakaza noma ukuzwa kwengalo, isihlakala noma isandla)
• Ukungasebenzi kahle kwe-Tibial nerve (ukulimala kwe-tibial nerve okuholela ekulahlekelweni kokuhamba noma ukuzwa onyaweni)

Umphumela ojwayelekile usho ukuthi inzwa ibonakala ijwayelekile.

Imiphumela engajwayelekile ingabangelwa:

• I-Amyloidosis (i-sural nerve biopsy isetshenziswa kakhulu)
• Ukususwa esikhundleni
• Ukuvuvukala kwemizwa
• Uchoko
• Ukulahleka kwezicubu ze-axon
• Ama-neuropathies we-Metabolic (ukuphazamiseka kwemizwa okwenzeka ngezifo eziphazamisa izinqubo zamakhemikhali emzimbeni)
• I-Necrotizing vasculitis
• I-Sarcoidosis

Izingozi zenqubo zingafaka:

• Ukusabela okweqile ku-anesthetic yendawo
• Ukungakhululeki ngemuva kwenqubo
• Ukutheleleka (ingozi encane noma kunini lapho isikhumba siphukile)
• Ukulimala unomphela kwezinzwa (akuvamile; kuncishiswe ngokukhethwa ngokucophelela kwesayithi)

I-nerve biopsy iyahlasela futhi ilusizo kuphela ezimweni ezithile. Khuluma nomhlinzeki wakho ngezinketho zakho.
