Ngenxa yokuthuthuka okuqhubekayo kwezobuchwepheshe bezokwelapha, ama-catheter okudilathwa kwe-bhaluni sekwaba ingxenye ebalulekile kwezokwelapha zanamuhla. Le thuluzi elithuthukile lezokwelapha lidlala indima ebalulekile ekwelapheni izifo eziningi, ikakhulukazi emigulweni ye-cardiovascular, emigulweni ye-peripheral vascular, kanye neziguli ze-structural heart.
As the name suggests, a balloon dilatation catheter is a catheter that achieves the purpose of treatment through balloon dilatation. Its working principle is to expand the balloon by injecting liquid or gas into the balloon, thereby expanding the narrowed or occluded blood vessels and restoring blood flow. This treatment method is not only less invasive, but also has significant efficacy, greatly improving the quality of life of patients.
Emkhakheni wezifo ze-cardiovascular, ama-catheter wokwandisa ibhaluni asetshenziswa kakhulu ekwelashweni kwesifo sokwehliswa kwecoronary atherosclerotic. Ngokuvia i-coronary angiography, odokotela bangabona kahle ingxenye enqamulelwe ye-umbhoshongo, bese besebenzisa i-catheter yokwandisa ibhaluni ukuze bandise le ngxenye enqamulelwe ukuze baphinde baphinde babuyisele i-umbhoshongo esimweni esithambile, ngaleyo ndlela bethuthukisa ukuhlinzekwa kwegazi kumyocardium.
Ekuphathweni kokugula kokuvinjelwa kwemithambo yegazi, ama-catheter okubeka umoya nawo adlala indima ebalulekile. Isibonelo, ekuphathweni kokuvinjelwa kwemithambo yegazi emalimbini aphansi, odokotela bangasebenzisa ama-catheter okubeka umoya ukuvulela imithambo yegazi evinjiwe, bayilungiselele ukuhamba kwegazi emahlombe aphansi, futhi bayokwenyusa ubuhlungu, ukungabi nombono nokunye kwezinye izimpawu zabaguli.
Ngaphezu kwalokho, ama-catheter okwelashwa kwe-bulb ayaphumelela nakanjani ekwelashweni kwezifo zenhliziyo zomkhiqizo. Isibonelo, ekwelashweni kokuhlukumezeka kwepulmonary valve, ukuhlasela kwe-aortic valve nezinye izifo, odokotela bangasebenzisa ama-catheter okwelashwa kwe-bulb ukuvula ama-valve awumfushane, ukuthuthukisa ukusebenza kwama-valve, futhi ngakho ukuthuthukisa izinga lempilo labaguli.
Ngenxa yezinzuzo zayo eziyingqayizivele, amakhethoni okukhipha amabhaluni adlala indima ebalulekile emkhakheni wezokwelapha zesimanje, elethela ithemba elisha ezigulini ezingenakubalwa.
