• Chii ichochi
• Mhando dzeStent

Simba chinhu chiduku chubhu yakagadzirwa nesimbi mesh uye yakawedzeredzwa, inoiswa mukati meseri, kuitira kuti igare yakavhurika, nokudaro ichidzivirira kuderera kweropa nekuda kwekuvhara.

Chii ichochi

Iyo stent inoshanda kuvhura midziyo ine hupamhi hwakadzikira, kuvandudza kuyerera kweropa uye huwandu hweoxygen inosvika kune nhengo.

Kazhinji, maSentents anoshandiswa muzviitiko zvevarwere vane chirwere checoronary chakadai seAcute Myocardial Infarction kana Unstable angina kana kunyange, mune chinyararire ischemia, uko murwere paanoona kuti ane mudziyo wakavharika kuburikidza nekuongorora bvunzo. Aya masendi anoratidzwa muzviitiko zvezvipingamupinyi zvinodzivirira zvinopfuura 70%. Inogona zvakare kushandiswa mune dzimwe nzvimbo senge:

• Carotid, coronary uye iliac arteri;
• Nzira dzemvura;
• Esophagus;
• Colon;
• Trachea;
• Pancreas;
• Duodenum;
• Urethra.

Mhando dzeStent

Mhando dze stents dzinosiyana zvinoenderana nemaitiro uye kuumbwa.

Zvinoenderana nechimiro, vanogona kuve:

• Zvinodhaka-kubiridzira stent: akafukidzwa nemishonga inozoburitswa zvishoma nezvishoma mutsinga kuitira kudzikisa kuumbwa kwetrombi mukati mayo;
• Yakaputirwa stent: kudzivirira nzvimbo dzisina kusimba kubva pakukombama. Inonyanya kubatsira mune aneurysms;
• Radioactive stent: bvisa madosi madiki emwaranzi muropa reropa kuti uderedze njodzi yekukuvara kweturuvara;
• Bioactive stent: akafukidzwa nezvinhu zvakasikwa kana zvigadzirwa.
• Biodegradable stent: kunyungudika nekufamba kwenguva, zvine mukana wekukwanisa kuita MRI mushure mekunyungudika.

Zvinoenderana nechimiro, vanogona kuve:

• Spiral stent: vanochinjika asi vasina kusimba zvakanyanya;
• Coil yakasimba: ivo vanonyanya kuchinjika, vachikwanisa kuchinjika kumakona emitsipa yeropa;
• Mesh yakasimba: musanganiswa wecoil uye spiral stents.

Izvo zvakakosha kusimbisa kuti iyo stent inogona kukonzera restenosis, apo tsinga inoderera zvakare, ichida, mune dzimwe nguva, kuiswa kweimwe stent mukati meyakavharwa stent.
