Ukuhlolwa kwama-radiographic okuvamile akuvumeli ukuhlolwa kwemithambo yegazi, i- lymph nodes kanye nemithanjeni, ngoba banamakhono afanayo okumangalisa maqondana nomswakama njengama-tissue azungezile. Ukuze bahlolisise ngokucophelela, inqubo ekhethekile isetshenziselwa ukusetshenziswa kwama-agent ehlukile-ama-angiography ezitsha. Le nqubo inikeza ukuxilongwa okusheshayo ngisho nezinyathelo zokuqala ze-pathologies ehlukahlukene ye-veins and arteries.
Iyini i-angiography yezingubo zentanyeni, futhi lokhu kwenziwa kanjani?
Lolu hlobo lokutadisha lenzelwe ukuthola izilonda ze-atherosclerotic ze-artery carotid. Zitholakala entanyeni, ngakho-ke i-angiography iqhutshwa kule ndawo.
Inqubo:
- Ukwelashwa kwesayithi lokugaya i-catheterization nge-anesthetic ye-antiseptic neyendawo.
- Isikhathi somkhumbi.
- Isingeniso sesethulo (tube tube).
- Ukufakwa kwe-Catheter.
- Isingeniso sesisombululo se-radiopaque emthini.
- Ucwaningo oluphezulu lwe-X-ray lwesayithi elichazwe ohlelweni nemishini ehlolwayo.
- Ukukhishwa kwe-catheter nesethulo.
- Faka isicelo sokubopha ibhande lokucindezela esakhiweni sokubanjwa komshini.
Kufanele kuqaphele ukuthi ukulandelana kwezenzo ezichazwe ngenhla kufana nokucwaninga kwazo zonke izitho. Izindawo zokufakelwa kwe-catheter kuphela zingahluka.
Izici ze-angiography yezimpahla zezinso
Ezimweni eziningi, ngokuhlola izinhlelo ezinkulu ze-vascular, i-X-ray i-substance i-injected in-aorta (transfemoral). Kodwa ekufundeni izinso, enye indlela yokungena ikhambi kungenzeka: ukuhumusha. Kuhilela ukungena kwe-catheter emkhakheni we-aorta wesisu.
Ngokufanayo, i-angiography yezimpahla zesigxobo sesisu sesenziwe. Ukwethulwa kwe-catheter ngokuhumusha kuqinisekisa ukusabalalisa okusheshayo kwesisombululo se-X-ray endaweni yokucwaninga kunomgwaqo wokudluliselwa kwemiphakathi.
Kanjani i-angiography yenhliziyo eyenziwa?
Lolu hlobo lwe-coronary examination (coronography), njengombuso, lwenziwa ngomjovo wezinto ezihlukile phakathi kwe-aorta yezinsikazi. Ezimweni ezingavamile, isitsha esikhulu ngakwesokunxele sikhethwe.
I-angiography ingenziwa futhi ucwaningo:
- ubuchopho ;
- i-fundus;
- izitho zomzimba;
- noma yiziphi izindawo zegciwane lokugaya;
- izitho zesikhumba esincane.
