Qhov sib txawv tseem ceeb ntawm anastomosis thiab collateral circulation yog tias anastomosis yog hais txog kev phais kev sib txuas ntawm ob lub qauv, tshwj xeeb tshaj yog ntawm cov hlab ntsha los yog ntawm ob lub voj voog ntawm txoj hnyuv, thaum lub collateral circulation yog ib qho kev sib hloov ncig ncig ntawm cov hlab ntsha lossis cov hlab ntsha. hla lwm txoj kev.
Anastomosis yog hais txog kev sib txuas ntawm ob lub tubular cov qauv xws li cov hlab ntsha, ob lub voj voog ntawm txoj hnyuv, thiab lwm yam. Nws yog ib qho tseem ceeb, thiab kev sib koom ua ke yuav tshwm sim vim qhov no. Meanwhile, collateral circulation yog ib tug alternate blood circulating pathway uas ua hauj lwm thaum lub ntsiab hlab ntsha yog thaiv los yog raug mob. Nws tshwm sim nyob ib ncig ntawm cov hlab ntsha uas thaiv, thiab nws muab cov ntshav txaus rau cov ntaub so ntswg. Yog li ntawd, kev sib koom ua ke yog ib qho tseem ceeb heev rau cov neeg mob uas muaj mob stroke ischemic, coronary atherosclerosis thiab peripheral artery disease.
Anastomosis yog dab tsi?
Tus anastomosis yog kev sib txuas ntawm ob lub qauv, tshwj xeeb tshaj yog ntawm cov qauv tubular. Nws tuaj yeem yog kev sib txuas ntawm cov hlab ntsha lossis nruab nrab ntawm ob lub voj voog ntawm txoj hnyuv. Circulatory anastomosis yog hais txog kev sib txuas ntawm ob cov hlab ntsha: ob lub hlab ntsha (arterio-arterial anastomosis), ob leeg leeg (veno-venous anastomosis), lossis nruab nrab ntawm cov hlab ntsha thiab cov hlab ntsha (arterio-venous anastomosis).
Daim duab 01: Anastomosis
Cov plab hnyuv anastomosis yog hais txog kev xaws ntawm ob qhov kawg ntawm txoj hnyuv ua ke tom qab tshem tawm ib feem ntawm txoj hnyuv phais. Lub anastomosis tuaj yeem yog qhov qub lossis txawv txav. Ntxiv mus, nws yuav tau los yog innate. Qhov txawv txav anastomosis uas yog congenital los yog kis tau feem ntau hu ua fistulas.
Yuav ua li cas nyiaj txiag kev lag luam?
Collateral circulation is an alternate blood circulating pathway around a blocked artery or vein. Nws tshwm sim ntawm preexisting vascular redundancy los yog ntawm cov ceg tshiab tsim ntawm cov hlab ntsha uas nyob ib sab. Yog li ntawd, nws yog ib tug network ntawm tshwj xeeb endogenous bypass hlab ntsha. Kev sib koom ua ke ua lub luag haujlwm tseem ceeb hauv cov neeg mob uas muaj mob stroke ischemic, coronary atherosclerosis, kab mob peripheral artery thiab lwm yam mob thiab kab mob. Nws muab kev tiv thaiv kev raug mob ischemic.

Qhov kev ua tau zoo ntawm kev sib koom ua ke hauv kev tiv thaiv infarction nyob ntawm qhov loj ntawm cov hlab ntsha. Yog hais tias txoj kab uas hla ntawm lub collaterals me me nws tsis tshua muaj peev xwm nqa cov ntshav txaus los tiv thaiv infarction. Tsis tas li ntawd, cov hlab ntsha hauv cov hlab ntsha muab lwm txoj hauv kev los ntawm cov ntshav mus rau myocardium ntawm lub plawv thaum muaj kab mob occlusive coronary artery. Yog li ntawd, qhov no coronary collateral muaj nuj nqi tiv thaiv tau lub plawv nres. Ntxiv mus, nyob rau hauv tib neeg lub hlwb, muaj ib tug network ntawm collateral arteries nyob rau hauv lub voj voog ntawm Willis, uas nyob rau hauv lub hauv paus ntawm lub hlwb.
Tsis tas li ntawd, kev sib koom ua ke yog qhov tseem ceeb hauv cov miv txhawm rau muab cov ntshav rau lawv sab nraub qaum thaum lawv muaj cov kab mob thromboembolism. Txawm hais tias cov hlab ntsha tseem ceeb raug thaiv vim muaj kev sib koom ua ke, lawv tau txais cov ntshav txaus rau lawv cov ntaub so ntswg ua haujlwm.
Dab tsi yog qhov zoo sib xws ntawm Anastomosis thiab Cov Nyiaj Txiag Nyiaj Txiag?
- Cov khoom ntiag tug tshwm sim los ntawm anastomosis tam sim no ntawm cov hlab ntsha uas nyob ib sab.
- Ob qho tib si anastomosis thiab collateral ncig pab txhawb cov ntshav mus rau hauv cov ntaub so ntswg thaum cov hlab ntsha tseem ceeb raug thaiv.
- Ob qho tib si anastomosis thiab collateral ncig tuaj yeem tshwm sim los yog tuaj yeem tsim kev phais.
Dab tsi yog qhov txawv ntawm Anastomosis thiab collateral Circulation?
Anastomosis yog ib qho kev sib txuas ntawm cov hlab ntsha lossis nruab nrab ntawm ob lub voj voog ntawm txoj hnyuv thaum lub collateral circulation yog lwm cov ntshav ntws los ntawm ib ncig ntawm cov hlab ntsha. Nws yog tshwm sim los ntawm anastomosis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm anastomosis thiab collateral ncig.
Summary – Anastomosis vs Collateral Circulation
Cov nyiaj txiag ncig yog qhov tshwm sim ntawm anastomosis. Anastomosis yog hais txog kev sib txuas ntawm ob lub cev tubular. Nws tuaj yeem yog kev sib txuas ntawm kev phais lossis kev sib txuas ntuj. Collateral circulation yog ib qho kev hloov ntshav uas ntws ncig ntawm cov hlab ntsha lossis cov hlab ntsha. Nws yog ib qho kev sib txuas ntawm cov hlab ntsha thiab muab kev tiv thaiv kev raug mob ischemic. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm anastomosis thiab collateral ncig.
