Taw qhia
Cov kab mob neurovascular (xws li, ischemic stroke, intracranial aneurysms, vascular malformations) sawv cev rau kev loj hlob thoob ntiaj teb kev noj qab haus huv, nrog kwv yees li 15 lab tus neeg mob stroke tshiab txhua xyoo. Cov txheej txheem Neurointerventional-Txoj kev cuam tshuam tsawg kawg rau kev qhib kev phais- tso siab rau cov cuab yeej tshwj xeeb xws li lub zais pa qhia catheters (BGCs) txhawm rau txhim kho kev nyab xeeb thiab ua haujlwm tau zoo. Kab lus no tshawb txog BGCs 'kev hloov pauv thev naus laus zis, kev cuam tshuam hauv chaw kho mob, thiab kev ua lag luam zoo.
Product Overview: Dab tsi yog Balloon Guide Catheters?
Lub zais pa qhia catheter yog cov cuab yeej tshwj xeeb endovascular tsim los rau:
1. Ua kom yooj yim nkag mus rau tortuous neurovascular anatomy.
2. Txhim kho microcatheters/microguidewires thaum ua haujlwm.
3. Tswj cov ntshav khiav (ib ntus occlusion) txhawm rau txhim kho kev xa khoom zoo.
Tsim & Khoom siv
1. Structure: Ib qho yooj yim catheter ncej (xws li, braided nitinol / stainless hlau) nrog ib tug deployable balloon (distal tip) thiab ib tug inflation / deflation tswj system.
2. Cov khoom siv Balloon: Nylon lossis polyurethane (sib npaug lub zog, yoog raws, thiab siab ua haujlwm rau cov hlab ntsha intracranial).
3. Sizing: Muaj nyob rau hauv 4–6 Fab Kis (Fr) txoj kab uas hla thiab qhov ntev sib txawv, haum rau cov hlab ntsha (xws li cov hlab ntsha hauv carotid, cov hlab ntsha hauv nruab nrab).
Mechanism ua haujlwm
BGCs tsim qhov "stagnant flow" ib puag ncig los pab kom muaj kev cuam tshuam meej:
1. Flow Arrest: Lub balloon inflates nyob rau hauv ib tug proximal hlab ntsha (xws li, ncauj tsev menyuam hauv carotid artery) mus rau ib ntus thaiv antegrade ntshav txaus.
2. Kev Tiv Thaiv Embolic: Cov dej ntws tsis tu ncua tiv thaiv cov thrombus fragments los ntawm kev tsiv chaw distally (txo cov teeb meem embolic).
3. Ntaus Stabilization: Stabilizes microcatheters/microguidewires, txhim kho kev koom tes nrog lub hom phiaj (xws li, thrombus, aneurysm caj dab).
Kev siv tshuaj kho mob
BGCs yog qhov tseem ceeb hauv ntau cov txheej txheem neurointerventional:
1. Kev Kho Mob Ischemic Stroke (AIS).
Nyob rau hauv mechanical thrombectomy (MT) rau lub nkoj loj occlusion (LVO):
a. BGCs txhim kho thawj zaug- dhau qhov kev rov ua dua tshiab (piv txwv li, SWIFT DIRECT, DEFUSE 3 qhov kev sim) los ntawm kev ua kom ruaj khov ntawm cov cuab yeej thrombectomy (stent retriever / aspiration catheter) thiab txo qis embolic khiav.
b. 2023 AHA/ASA cov lus qhia pom zoo siv BGC los ua kom zoo dua cov txiaj ntsig rov qab.
2. Intracranial Aneurysm Embolization
Rau qhov nyuaj aneurysms (piv txwv li, dav-caj dab, fusiform):
a. BGCs txo cov pulsatile ntws thaum lub sij hawm coil xa mus, txo cov coil tsiv teb tsaws thiab txhim kho cov ntim ntom ntom (ntev - lub sij hawm occlusion tus nqi).
b. Pab kom cov txheej txheem siab tshaj xws li balloon-pab coiling (BAC) lossis stent-pab coiling (SAC).
3. Vascular Angioplasty/Stenting
a. Rau intracranial atherosclerotic stenosis los yog dissection:
BGCs muab cov dej ntes kom nyab xeeb xa cov stents / ua haujlwm angioplasty, txo cov kev pheej hmoo ntawm thromboembolic.
