I-Angiography yeempahla zamalungu angaphantsi angabonisa ezininzi izifo ezijikelezayo, kunye nezinye iingxaki ezinzulu. Uphando luqhutywa ngeendlela ezininzi. Yonke into incike kwixinzelelo yesifo esityholo kunye nesimo somguli.
Iintlobo zee-angiography zeziphelo eziphantsi
Ukufundwa kweempahla zecala elingaphantsi kuninzi kwenziwa rhoqo ukufumanisa isifo esifana ne- thrombophlebitis . Kubaluleke kakhulu ukuxilonga ngokukhawuleza ngaphambi kokuba eso sifo siye kwisigaba esiyingozi nakunzima. Ukongeza, i-angiography imiselwe ngeengxaki ezilandelayo:
- ukunciphisa okanye ukucima imida;
- ukuphelisa i-atherosclerosis;
- nzakala kunye nokulimala;
- aneurysms;
- ukuxuba kweemvini;
- isifo sesifo sesifo sikashukela;
- ukujonga emva kokusebenza.
I-Angiography ingenziwa ngokusetyenziswa:
- i-tomography (CT);
- izifundo ze-radiopaque;
- i-ultrasound dopplerography;
- i-multispiral computed tomography (MSCT).
Ngombulelo we-CT engiography yeempahla zecala eliphantsi, kunokwenzeka ukuba ufunde ngokubanzi iinkcukacha zelizwe legazi, uhlolisise nayiphi na inxalenye yesitya kwaye ugqibe ukuphulwa kwegazi.
I-MSCT ye-angiography yeziphelo ezingezantsi yintsikiti ephezulu ye-multislice ebizwa nge-tomography yesibhedlele esinobuchule kunye nokusetyenziswa kweempahla ezichaseneyo. Ngokuqhelekileyo kubelwa ukuba kuchonge iingxaki ezinjenge:
- angiodysplasia;
- i stenoses ;
- ukunyuka;
- thromboses;
- ukulimala kabuhlungu kwamalungu.
Inkqubo iphinda ikhuthazwe ukulawulwa kwama-prostheses asele kunye nama-static vascles.
Ndiyabulela kule ndlela yokuxilonga, oyingcali ufumana imifanekiso emithathu ye-3-D yesitishi somsebenzi. Le ndlela ithathwa njengeyona ndlela iphambili kakhulu kwaye ikwazisa.
Umgaqo woviwo
I-Traditional i-angiography phantsi kwe-anesthesia yendawo. I-MSCT kuphela iya kuba yinto ehlukile. Ngaphambi kokuxilongwa, i-artery iyabulawa kwaye i-ejenti eyahlukileyo ifakwe. Kwiindlela ezintsha zokuphanda, ulwahlulo lulawulwa ngokulandelelana.
Inkqubo ngokwayo ingathathi ngaphezu kwemizuzu engama-20. Kule meko, ingcali ngexesha elithile lingakucela ukuba ubambe umoya. Oku kuyimfuneko ukuze ufumane imifanekiso ecacileyo. Emva koviwo, isiguli kufuneka sichithe ixesha elithile phantsi kweliso lwabasebenzi bezonyango ukuba bangabandakanyi amathuba okulahleka kwegazi kwindawo yokuqhawula kunye nokufakelwa kwecatheter (ngamanye amaxesha kwenzeka ukuba igazi aliyeki). Imifanekiso efunyenweyo ifundwa yiingcali, kwaye i-diagnostic yokugqibela isenziwa.
