Lub sij hawm stent retriever summarizes lub epoch-ua neurointerventional ntaus ntawv ntawm thrombectomy stent. Lub sij hawm stent los ntawm British kws kho hniav Charles Thomas Stent. Xyoo 1916, Dutch orthopedic kws phais neeg Johannes Fredericus Esser tau siv cov khoom tsim los ntawm Stent thaum ua kev phais lub ntsej muag rau cov tub rog los ntawm Ntiaj Teb Tsov Rog I. Hauv Suav, lo lus stent txhais tau hais tias yog ib qho bracket. Lo lus feem ntau siv hauv Interventional Radiology yog stenting, uas txhais tau hais tias muab tso rau hauv stent. Thawj tus siv stents hauv cov hlab ntsha los txhawb cov hlab ntsha tuaj yeem yog pab pawg ntawm Argentinian kws kho mob hluav taws xob Julio Palmaz hauv Tebchaws Meskas. Xyoo 1985, lawv tau ua tiav kev sim nrog cov hlau tsis muaj hlau txuas ntxiv uas tsim los ntawm lawv tus kheej ntawm cov hlab ntsha loj ntawm cov dev (xws li cov hlab ntsha carotid). Tsab ntawv tau luam tawm hauv "Radiology" nrog lub npe "Expandable Intraluminal Graft: Ib Txoj Kev Kawm Ua Ntej. Ua Haujlwm hauv Kev Ua Haujlwm". Txij thaum ntawd los, stent tau maj mam tau siv dav hauv kev kho mob endovascular ntawm aorta, coronary artery, qis kawg ntawm cov hlab ntsha thiab lwm yam.
Kev nce qib hauv cov ntaub ntawv tshawb fawb tau muab kev lees paub muaj zog rau kev txhim kho cov khoom siv rov ua dua tshiab, thiab kev siv dav hauv kev kho mob nickel-titanium alloy stents tau tso lub hauv paus rau qhov tshwm sim ntawm thrombectomy stents. Lub tswv yim ntawm kev nco alloy tau npaj los ntawm Greninger thiab Moor-adina hauv kev soj ntsuam kev kawm ntawm tooj dag (muaj zinc thiab tooj liab). Buehler ntawm Naval Ordnance Laboratory (NOL) thiab nws cov npoj yaig tau tshawb pom nickel-titanium alloy hauv xyoo 1963 thiab hu ua Nitinol (Nickel titanium Naval Ordnance Laboratory).
Nickel-titanium zoo nco alloy yog ib qho intermetallic compound tsim los ntawm kev sib cuam tshuam ntawm equiatomic ratio titanium atoms thiab nickel atoms. Nws muaj superelasticity zoo heev thiab cov duab cim xeeb, zoo biocompatibility thiab corrosion kuj. Lub alloy tuaj yeem deformed random. Thiab nws muaj peev xwm deformation zoo nrog lub cev, nruab nrab deformation kuj, siab zog ntawm alloy, thiab txo qis elastic modulus dua lwm yam hlau. Cov txiaj ntsig no ua rau titanium-nickel alloy yog cov khoom siv kho mob zoo tshaj plaws thiab cov khoom siv vascular stent. Xyoo 1984, Cragg thawj zaug qhia txog kev kho mob endovascular ntawm Nitinol stents. Cov nickel-titanium alloy laser-engraved stent yog ua tiav los ntawm kev siv cov nickel-titanium alloy hollow raj nrog lub tshuab laser engraving. Cov chav tsev stent tau sib xyaw ua ke thiab ua tiav los ntawm kev kho cua sov nthuav dav, passivation polishing thiab lwm cov txheej txheem tom qab ua tiav. Nws muaj kev ua haujlwm siab precision thiab haum rau ntau lawm. Nws yog cov txheej txheem dav siv rau kev tsim cov intracranial thiab peripheral nws tus kheej nthuav stents.
Lub cerebrovascular thrombus stent retriever sprouted nyob rau hauv lub caij nplooj zeeg ntawm 1995. American UCLA kws tshawb fawb Dr Pierre Gobin thiab JP Wensel siv urokinase rau arterial thrombolysis rau cov neeg mob thaum ntxov stroke nruab nrab cerebral artery thrombosis, tab sis cov hlab ntsha tsis qhib. Ob tus kws tshawb fawb tau ntxhov siab thiab sim tsim ib qho cuab yeej los tshem tawm cov ntshav txhaws thiab txo qhov kev pheej hmoo los ntshav. Cov cuab yeej zoo li kauv tau tsim ua ntej thiab ua los ntawm Nitinol nco alloy. Tom qab kev txhim kho tas mus li, qhov kev sim tshuaj tau pib thaum lub Tsib Hlis 2001, thiab thawj 2 tus neeg mob stroke tau txais TIMI qib 3 recanalization nrog stent. Txawm hais tias cov cuab yeej thrombectomy tsis tau txais cov pov thawj qib siab ntawm kev kho mob, nws tau txhawb kev ntseeg siab ntawm cov kws tshawb fawb tom qab los ua cov kev tshawb fawb ntxiv.
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab kev txhim kho qib ntawm nickel-titanium alloy stents thiab kev nthuav dav ntawm daim ntawv thov kev lag luam, stent retriever tau nkag mus rau theem ntawm kev kho mob stroke los ntawm kev sib tsoo. Lub intracranial thrombectomy stent retriever yog tus kheej-expandable retrievable stent ua los ntawm classic nickel-titanium alloy. Tus tsim qauv siv yog los pab rau hauv embolization ntawm wide-caj dab intracranial aneurysms. Nws tau pom tias thaum lub stent xav tau repositioned thaum siv, lub stent tuaj yeem rub ncaj qha yam tsis tau rov qab thiab tso tawm.
Thaum Lub Peb Hlis 3, 2008, tus poj niam muaj hnub nyoog 67- xyoo uas muaj mob stroke mob stroke kho los ntawm Hans Henkes pab neeg hauv Stuttgart, lub teb chaws Yelemees, tsis pom kev kho mob li ntawm 30 feeb tom qab intravenous thrombolysis, thiab tom qab ntawd txiav txim siab mus txuas ntxiv kev kho mob. thaum pib kho endovascular. Tsis muaj recanalization ntawm lub nkoj occluded tau pom tom qab maj mam tshem cov thrombectomy txhuam (ib qho thrombus retriever thaum ntxov). Xav txog qhov xwm txheej ceev thiab qhov tseeb tias tsis muaj lwm yam khoom siv, lub stent tau muab tso rau ntawm lub nkoj occluded. Tom qab ob peb feeb, lub stent retrieval tau maj mam muab tshem tawm nyob rau hauv tas li aspiration. Angiography tau pom ua tiav qhov kev rov ua tiav ntawm cov hlab ntsha, tsis muaj ib puag ncig embolism lossis vasospasm, tab sis thrombus tau pom hauv stent. Qhov kev sim no nrog stent retriever tau ua tiav! Matthew J Gounis tau luam tawm ib tsab xov xwm ntawm kev tshawb fawb hauv vitro hauv xyoo 2008, qhia txog cov txheej txheem ntawm kev siv stent tshem tawm thrombus hauv vitro qauv. Txoj kev tshawb fawb SWIFT luam tawm xyoo 2012 yog qhov tseem ceeb. Xyoo 2015, MR CLEAN txoj kev tshawb fawb tau tshaj tawm tias stent thrombectomy yog lub hauv paus ntawm cov pov thawj hauv ntau qhov chaw kuaj mob loj. Txij thaum ntawd los, lub sijhawm tshiab ntawm kev kho mob stroke tau qhib.
