I-Angiography yezimpahla zamalungu angaphansi angabonisa izifo eziningi ze-circulatory, kanye nezinkinga eziningi ezingathí sina. Ucwaningo luqhutshwa ngezindlela eziningana. Konke kuncike ekutheni isifo sesifo nesimo sesiguli.
Izinhlobo ze-angiography zamaphethelo aphansi
Ukutadisha izitsha zemikhawulo engezansi kuvame ukuqhutshwa ukuze kuhlolwe isifo esifana ne- thrombophlebitis . Kubalulekile ukuxilonga ngokushesha ngangokunokwenzeka ngaphambi kokuba lesi sifo singene esigabeni esiyingozi nakakhulu. Ngaphezu kwalokho, i-angiography inqunywe ngezinkinga ezilandelayo:
- ukunciphisa noma ukuvinjelwa kwemithanguzo;
- ukuqeda ukuqina kwe-atherosclerosis;
- ukulimala nokulimala;
- aneurysms;
- i-fusion ye-veins;
- isifo sikashukela samasondo;
- Ukubheka okulandelayo.
I-Angiography ingenziwa ngokusebenzisa:
- i-tomography ehlanganisiwe (CT);
- izifundo ze-radiopaque;
- i-ultrasound dopplerography;
- i-multispiral computed tomography (MSCT).
Ngenxa ye-CT engiography yezimpahla zomkhawulo ophansi, kungenzeka ukutadisha ngokuningiliziwe isimo segazi, uhlole ngokucophelela noma iyiphi ingxenye yesitsha bese unquma ukwephulwa kwegazi.
I-MSCT i-angiography yamaphethelo aphansi ingumthamo omkhulu we-multislice we-tomography webhedi elibhekene nokusetshenziswa kwemikhumbi ehlukile. Ngokuvamile kunikezwa ukukhomba izinkinga ezifana nalezi:
- i-angiodysplasia;
- i-stenoses ;
- ukungena;
- i-thromboses;
- ukulimala okulimazayo kwamalungu.
Le nqubo iphinde ikhuthazwe ukulawulwa kwe-prostheses esungulwe kanye nama-vascular stents.
Ngenxa yalendlela yokuxilongwa, lochwepheshe uthola izithombe eziningi ze-3D-D zesiteshi esiphezulu. Le ndlela ibhekwa njengeyona ehamba phambili kakhulu futhi efundisayo.
Isimiso sokuhlolwa
Indabuko i-angiography ngaphansi kwe-anesthesia yendawo. I-MSCT kuphela izoba okuhlukile. Ngaphambi kokuxilongwa, i-artery ihlatshwa futhi i-agent ehlukile ijojowe. Ezindlela ezintsha zokuphenya, ukuhlukana kuhlinzekwa nge-intravenously.
Inqubo ngokwayo ingathathi imizuzu engaphezu kwengu-20. Kulesi simo, ochwepheshe ngesikhashana angase akucele ukuthi ubambe umoya wakho. Lokhu kuyadingeka ukuze uthole izithombe ezicacile. Ngemuva kokuhlolwa, isiguli kufanele sisebenzise isikhathi esingaphansi kokuqondiswa kwabasebenzi bezokwelapha ukuze kungabikho amathuba okulahleka kwegazi esakhiweni sangasese kanye nokufakwa kwamakhemikhali (ngezinye izikhathi kwenzeka ukuthi igazi alimeli). Izithombe ezitholiwe zifundwa ngabathengi, kanti ukuhlolwa kokugcina kwenziwa.
