Ntshav ntawm cov hlab ntsha (angiospasm) yog ib txoj kev nqus ntawm lub lumen ntawm cov hlab ntsha (loj thiab me), uas ua rau txo qis hauv cov ntshav ntawm cov khoom sib thooj (ntaub so ntswg). Yog li ntawd, kev noj zaub mov ntawm lub cev (cov nqaij) nrog cov pa yog cuam tshuam thiab cov pa roj carbon dioxide.
Ua rau ntawm vasospasms
Qhov qis ntawm lub lumen ntawm cov hlab ntsha tuaj yeem yog vim muaj kev sib ntau thiab ntev heev ntawm cov nqaij ntshiv ntawm cov vascular phab ntsa (nce ntawm cov pob txha). Lub tswv yim ntawm qhov tshwm sim no yog txuam nrog kev cuam tshuam ntawm kev siv ntawm cov qog ntawm cov nqaij ntshiab ntawm cov hlab ntsha, uas muaj nyob rau hauv qhov ua txhaum ntawm cov txheej txheem metabolic los ntawm cov kua qaub ntawm cov kua qaub, cov tshuaj calcium, thiab sodium. Qhov no ua rau muaj kev cuam tshuam ntawm qhov kev hloov ntawm lub sijhawm ntawm cov leeg mob thiab qhov contraction.
Cov kab mob vascular feem ntau pom nyob rau hauv cov kab mob nrog kev hloov ntawm cov hlab ntsha thiab lawv lub paj hlwb (vasculitis, atherosclerosis, aneurysms, thiab lwm yam) lossis ua txhaum ntawm txoj cai tswj hwm neurohumoral ntawm vascular tone (hypothalamic syndrome, hypertension, pathological menopause, neurosis, etc.). ).
Cov xwm txheej muaj feem rau qhov kev txhaum no yog:
- haus luam yeeb;
- quav quav cawv;
- kev qaug nrog cov hlau lead lossis carbon disulfide;
- frostbite thiab rov qab mob hypothermia;
- qhov kev nyuab siab;
- ntshav qab zib mellitus;
- kub siab.
Cov tsos mob thiab hom kev vas sab
Nyob ntawm seb qhov chaw, ntau hom kev sib hlab ntawm cov hlab ntsha nrog ntau yam tshwm sim. Cia peb xav txog qhov tseem ceeb.
Ntshav ntawm cov hlab ntsha peripheral
Cwj pwm los ntawm paroxysmal ischemia ntawm cov extremities. Lub tswv yim no muab cov kab ke nram no:
- Reynaud's syndrome yog ib qho ntawm cov hlab ntsha ntawm peripheral, uas nyob rau theem peb rov qab hloov: ischemia, cyanosis thiab hyperemia. Nyob rau hauv thawj theem muaj ib tug spasm ntawm me me arterioles, ib tug narrowing ntawm lumen ntawm capillaries. Qhov thib ob - lub stagnation ntawm cov ntshav nyob rau hauv lub venules, capillaries thiab arteriovenous anastomoses. Qhov thib peb theem yog tsiag ntawv los ntawm kev nthuav dav ntawm cov hlab ntsha. Nyob rau hauv cov ntaub ntawv no, muaj ib qho kev ua txhaum ntawm kev txhawj xeeb.
- Livedo net - tau pom nrog cov cua txias tsis txaus thiab nws yog qhov txawv ntawm qhov pom ntawm daim tawv nqaij ntawm cov ceg, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam ntawm lub plawv (thaj tsam chaw yog surrounded ntawm ib lub cyanotic rim).
- Acrocyanosis - kev ua los ntawm cyanosis ntawm daim tawv nqaij ntawm cov extremities, tshwj xeeb tshaj yog cov ntiv tes thiab sab nraum qab ntawm txhais tes, txuam nrog cov teebmeem ntawm txias, thiab zoo nkaus ntawm loog. Nyob rau hauv cov ntaub ntawv no, tej zaum yuav muaj ntau tawm hws.
- Kev tuag - tsim los ntawm kev mob khaub thuas thiab dampness thiab yog thaum yus pom ntawm qhov tawv nqaij ntawm cyanotic liab tsos nqaij daim tawv, ib qho kev xav ntawm khaus thiab hlawv.
Ntshav ntawm cov hlab ntsha loj (spasm ntawm ob txhais ceg)
Cwj pwm ntawm lub pob yas, tom qab xiav, thiab tom qab kev txom nyem ntawm lub siab - xim liab. Muaj qaug zog ntawm ob txhais ceg, sib quas ntus vim muaj mob, txias qe.
Ntshav ntawm cov hlab ntsha ntawm lub plawv (spasm ntawm coronary vessels)
Cov tsos mob tshwm sim xws li nias lub siab tom qab lub zog ntawm lub mis, uas tshwm sim ntau dua thaum hmo ntuj los yog thaum ntxov thaum sawv ntxov, pw. Thaum lub sij hawm nres, tus electrocardiogram qhia txog tus cwj pwm txawv, thaum txoj cai, cov hlab ntsha leeg tsis raug thaiv thiab tsis muaj cov cim qhia txog kev hnoos tsho ntawm cov tshuaj tua kab mob ntawm myocardium.
Ntshav ntawm cerebral vessels (spasm ntawm cerebral vessels)
Nquag hloov los ntawm qhov hnyav ntawm mob taub hau thiab kiv taub hau, xeev siab, qoj pob ntseg , tsis nco, qee zaus - tsis nco qab. Feem ntau, tus mob cerebral vasospasm yog txuam nrog kev ywj pheej ntawm caj dab lub caj dab vim yog osteochondrosis, cov tsos mob ntawm qhov uas mob mob hauv lub caj dab, tsis hnov ntawm txhais tes, hloov mus rau ntawm qhov muag ntawm lub qhov muag.
Yuav ua li cas txo vasospasm?
Kev kho ntawm vasospasm yuav tsum tau sau los ntawm kws kho mob tom qab kuaj tag nrho. Txawm li cas los xij, hauv tsev, koj tuaj yeem siv cov txheej txheem no:
- Ntxuav nrog dej txias.
- Noj Corvalol (30 tee) los yog tincture ntawm valerian (20 tee).
- Zaws khaub zig thiab tom qab lub taub hau.
- Tuav koj ob txhais taw hauv dej txias (li 3 feeb).
- Zom cov extremities.
