I-CT Angiogram ukuze wazi kakuhle ngemithambo yegazi yakho! Singathetha ngale nto?

Ngamanye amaxesha oogqirha bethu kufuneka bajonge ngokusondeleyo imithambo yegazi engaphakathi emizimbeni yethu. Ukuze sichaze ngokuchanekileyo, ukuze sibone ukuba kukho ingxaki na ngaphakathi kwemithambo yegazi, ukuba kukho ukuvaleka kwenye indawo, ukuba kukho ukudumba okuncinci okufana nebhaluni. Kulapho olu vavanyo lukhethekileyo olubizwa ngokuba yi-CT Angiogram lusinceda khona. Makhe sibone ukuba yintoni le, yenziwa njani, kwaye kutheni ifuneka?

Yintoni i-CT Angiogram?

Ngamafutshane, i-CT angiogram luvavanyo oluthatha imifanekiso eneenkcukacha zemithambo yegazi yakho kunye nezicubu ezijikeleze yona. Ifana nefoto, kodwa icace ngakumbi. Olu vavanyo luhlala lwenziwa ukujonga ukuvaleka okanye ukuncitshiswa kwemithambo yegazi ehambisa igazi entliziyweni yakho, ebizwa ngokuba yi-coronary arteries, okanye oko oogqirha bakubiza ngokuba sisifo se-coronary artery . Ngenxa yesi sizathu, ngamanye amaxesha ibizwa ngokuba yi-coronary CT angiogram, okanye i-CCTA.

Zeziphi ezinye izifo ezisetyenziswa yi-CT angiogram ukuxilonga?

Le CT angiogram isetyenziselwa ukubona izinto ezininzi, kungekuphela nje imithambo yegazi yentliziyo. Cinga ngezi meko:

• I-Aneurysm: Oku kwenzeka xa umthambo wegazi, umzekelo i-aorta yakho okanye umthambo wegazi engqondweni yakho, uvuvukala ngendlela engaqhelekanga, njengebhaluni.
• Ukuqhekeka kwe-aorta: Oku kwenzeka xa kukho ukukrazuka kumaleko angaphakathi eludongeni lwe-aorta yakho.
• Ukukhubazeka kwemithambo yegazi: Le yimeko apho imithambo yegazi kunye nemithambo yegazi zidibene khona, ingakumbi kwiindawo ezifana nobuchopho.
• Isifo semithambo ye-carotid: Ukuvaleka okubangelwa kukugcwala kwamafutha (i-plaque) kwimithambo ethwala igazi liye engqondweni yakho.
• Isifo semithambo yegazi ejikeleze imithambo: Imeko apho i-plaque iqokelelana khona kwimithambo yegazi emilenzeni okanye ezingalweni zakho.
• I-Pulmonary embolism: Ihlwili legazi elihlala emiphungeni.
• Ukuqhaqha kwemithambo yentliziyo okuzenzekelayo (SCAD): Ukukrazuka okanye ukwahlulwa ngequbuliso kodonga lwemithambo yentliziyo entliziyweni.
• Ukulimala okubangelwa kukwenzakala: Xa into ebukhali ibetha esifubeni, entanyeni, okanye entloko, nto leyo ebangela umonakalo kwimithambo yegazi.

Ayisiyiyo loo nto kuphela, kodwa ngamanye amaxesha ugqirha wakho usebenzisa i-CT angiogram ukucwangcisa kwangaphambili utyando okanye ezinye iinkqubo zonyango. Umzekelo, inokukunceda ujonge imithambo yakho yentliziyo ngaphambi kokuba wenze utyando lokutshintsha ivalvu yentliziyo, utyando lwe-heart bypass, okanye ukubekwa kwe-stent.

"Ngokwenyani, i-CT angiogram ngumfanekiso ovela kolu vavanyo. I-CT angiography yindlela esetyenziswayo ukuthatha le mifanekiso. Kodwa njengoko sithetha, zombini zisetyenziselwa uvavanyo oluya kulo. Abanye abantu balubiza ngokuba yi-CTA ngamafutshane."

Isebenza njani i-CT angiography?

Ubusazi na ukuba ne-CT scan eqhelekileyo ingathatha imifanekiso eneenkcukacha, enemilinganiselo emithathu (3D) yangaphakathi emizimbeni yethu? Kungenxa yokuba i-scanner ithatha amakhulu emifanekiso eqingqiweyo enamacala amabini (2D). Ikhompyutha emva koko ithunga yonke le mifanekiso ukuze yenze imifanekiso ye-3D esemgangathweni ophezulu. Nangona kunjalo, umahluko omkhulu phakathi kwe-CT scan kunye ne-CT angiography kukusetyenziswa kwedayi yokwahlulahlula .
