PTA (Percutaneous Transluminal Angioplasty) thiab balloon angioplasty feem ntau siv sib hloov, tab sis lawv tsis yog tib yam. Cov txheej txheem ob qho tib si sib xws thiab yog qhov kev kho mob tsawg kawg nkaus rau qee yam mob vascular, tshwj xeeb yog cov uas cuam tshuam nrog cov hlab ntsha nqaim lossis thaiv cov hlab ntsha. Txawm li cas los xij, muaj qhov sib txawv nuanced ntawm ob.
Balloon angioplasty yog cov txheej txheem tshwj xeeb siv thaum PTA. Nws suav nrog kev tso lub catheter nrog lub zais pa deflated ntawm nws lub ntsis rau hauv cov hlab ntsha uas nqaim lossis thaiv cov hlab ntsha. Thaum lub catheter mus txog qhov chaw, lub zais pa yog inflated, compressing cov quav hniav los yog fatty deposits tiv thaiv cov hlab ntsha. Qhov kev ua no nthuav dav cov hlab ntsha thiab kho cov ntshav ntws. Lub zais pa yog ces deflated thiab thim.
Lub hom phiaj tseem ceeb ntawm balloon angioplasty yog txhawm rau txo cov tsos mob tshwm sim los ntawm cov hlab ntsha txhaws, xws li mob hauv siab (angina) vim kab mob plawv lossis mob ceg (claudication) vim kab mob peripheral artery. Nws feem ntau siv ua ke nrog lwm yam kev kho mob, xws li stent tso, los pab kom cov hlab ntsha qhib tom qab txoj kev.
PTA yog ib lub ntsiab lus dav dav uas suav nrog ntau yam txuj ci siv los nthuav cov hlab ntsha uas nqaim lossis cuam tshuam. Thaum lub zais pa angioplasty yog ib feem tseem ceeb ntawm PTA, PTA tuaj yeem koom nrog lwm txoj hauv kev tshaj li lub zais pa, xws li atherectomy (tshem cov quav hniav ntawm cov hlab ntsha) lossis laser angioplasty.
Hauv qhov tseem ceeb, PTA yog hais txog txhua tus txheej txheem uas siv cov txheej txheem cuam tshuam tsawg kawg nkaus los txhim kho cov ntshav ntws hauv cov hlab ntsha nqaim. Nws yog ntau txoj hauv kev ua haujlwm nyob rau hauv ntau qhov chaw ntawm lub cev, suav nrog lub plawv (cov hlab ntsha), ob txhais ceg (peripheral hlab ntsha), caj dab (cov hlab ntsha carotid), thiab raum (lub raum hlab ntsha), thiab lwm yam.
Scope: Balloon angioplasty yog ib qho tshwj xeeb ntawm PTA uas tshwj xeeb siv lub zais pa kom nthuav cov hlab ntsha.
Cov txheej txheem: PTA encompasses ib tug dav spectrum ntawm cov txheej txheem tshaj balloon inflation, nrog rau kev siv lasers los yog atherectomy li.
Daim ntaub ntawv: Thaum lub zais pa angioplasty tau siv dav hauv cov hlab ntsha thiab cov hlab ntsha peripheral, PTA npog ntau qhov kev cuam tshuam ntawm vascular hauv ntau qhov chaw anatomical.
