Stent

I-stent yishubhu elincane elibekwe esakhiweni esingenalutho emzimbeni wakho. Lesi sakhiwo singaba umthambo, umthambo, noma esinye isakhiwo esifana neshubhu ethwala umchamo (ureter). I-stent igcina isakhiwo sivulekile.

Lapho kufakwa i-stent emzimbeni, inqubo ibizwa ngokuthi yi-stenting. Kunezinhlobo ezahlukahlukene zama-stents. Iningi lenziwe ngezinto zensimbi noma zepulasitiki ezinjenge-mesh. Noma kunjalo, ukufakelwa kwe-stent kwenziwa ngendwangu. Zisetshenziswa emithanjeni emikhulu.

Umthambo we-coronary stent uyishubhu elincane, elizikhulisayo, lensimbi yensimbi. Ibekwe ngaphakathi komthambo we-coronary ngemuva kwe-balloon angioplasty. Le stent ivimbela umthambo ekuvaleni kabusha.

I-stent eluting stent ifakwe umuthi. Lo muthi usiza ngokuqhubekayo ukuvimbela imithambo ukuthi ingaphinde ivaleke. Njengamanye ama-coronary artery stents, ishiywa unomphela emthanjeni.

Isikhathi esiningi, kusetshenziswa ama-stents lapho imithambo yegazi iba mincane noma ivinjiwe.

Ama-stents ajwayele ukusetshenziselwa ukwelapha lezi zimo ezilandelayo ezibangelwa yimithambo yegazi evinjiwe noma elimele:

• Isifo senhliziyo seCoronary (CHD) (i-angioplasty nokubekwa kwe-stent - inhliziyo)
• I-peripheral artery disease (i-angioplasty ne-stent replacement - imithambo yegazi)
• I-vein thrombosis ejulile (i-DVT)
• I-renal artery stenosis
• I-aortic aneurysm yesisu (ukulungiswa kwe-aortic aneurysm - endovascular)
• Isifo semithambo seCarotid (ukuhlinzwa komthambo we-carotid)

Ezinye izizathu zokusebenzisa ama-stents zifaka:

• Ukugcina uvule i-ureter evinjiwe noma eyonakele (izinqubo zomchamo ezisebenza ngazinye)
• Ukwelapha ama-aneurysms, kufaka phakathi i-thoracic aortic aneurysms
• Ukugcina i-bile igeleza emibhobho ye-bile evinjiwe (ukuqina kwe-biliary)
• Kukusiza uphefumule uma uvinjelwe ezindleleni zomoya

Izihloko ezihlobene zifaka:

• Ukubekwa kwe-angioplasty nokuqina - inhliziyo
• Ukubekwa kwe-angioplasty kanye ne-stent - imithambo yegazi
• Izinqubo zomchamo ezinamandla
• I-Transjugular intrahepatic portosystemic shunt (AMACEBISO)
• Ukuhlinzwa komthambo weCarotid
• Ukulungiswa kwe-aortic aneurysm - endovascular
• I-aneurysm ye-Thoracic aortic

Ama-stents akhipha izidakamizwa; Ama-stents we-Urinary noma we-ureteral; Ama-coronary stents

• Ukukhishwa kwe-angioplasty ne-stent - inhliziyo
• Ukubekwa kwe-Angioplasty kanye ne-stent - umthambo we-carotid - ukukhishwa
• Ukubekwa kwe-angioplasty nokuma okuqinile - imithambo yegazi - ukukhipha
• Ukulungiswa kwe-aortic aneurysm - endovascular - discharge
• I-catheterization yenhliziyo - ukukhishwa
• Ukuhlinzwa komthambo weCarotid - ukukhipha
• Izinqubo zomchamo ezinamandla - ukukhipha
• Ukudlula emthanjeni wokudlula - umlenze - ukukhishwa

• Umthambo weCoronary stent
• I-Coronary artery balloon angioplasty - uchungechunge
