Venous kuchulukana mutu - mmene kukhala nawo

Kuphwanya venous mitu outflow mu nthawi yathu si zachilendo. N'zosadabwitsa, chifukwa anthu ambiri kuwononga nthawi mu malo atakhala nthawi zambiri mutu wake chikalata chilichonse, buku kapena kope. Zonsezi, ndithudi, zimakhudza outflow venous mutu.

Koma ife tisanati alankhulepo za zomwe zikuwoneka ndi kuchulukana venous ndi mmene kuthana nazo, muyenera kulankhula za mmene kumanga ka kotunga magazi mu ubongo. Mu gawo ili la thupi magazi amazungulira mosiyana mu ziwalo zina. Anabwera magazi awo wolumikizira, afika mu capillaries ozungulira zimakhala ndi kupereka mpweya ndi zinthu zina zofunika akulowa mitsempha oziziritsa kuti patsekeke cranial lotseguka mu sinuses ndi venous (nkusani). nkusani awa anapanga fupa la chigaza ndi pamwamba ubongo, kotero buku ake sangakhoze kusintha. Komabe, magazi iwo zambiri amalandira kwambiri poyerekeza akhoza kumakhalamo okha, chotero ntchito zawo mu malo oyamba ndi kuteteza venous kuchulukana zinthu pangozi pamene magazi amatuluka ubongo kwambiri kuposa masiku.

Kuwonjezera zipangizozi, lamulo la kuthamanga imagwiridwa ndi ziwiya oziziritsa, amene ali tcheru kusintha magazi. Mwachitsanzo, pamene magazi ambiri ku ubongo amalandira zolandilira wapadera padziko Mitsempha kutumiza mbendera ubongo zomwe adzalamulira kukuza lumen wa mitsempha, amene bwino venous outflow ndi Sachita magazi.

Koma si nthawi zonse bwino thupi azolowere kusintha zinthu mkati. Nthawi zina venous stasis kumachitika chifukwa chakuti akusokoneza ndi maselo pamwamba. Komanso pali zina zoyambitsa matenda a mkhutu venous ngalande: kuyan'anila kuwala kumachitika nthawi yaikulu thupi, mu malo supine popanda pilo, pamene kufinya khosi kolala. Lolemera kuyan'anila omwewo akapezeka zosiyanasiyana matenda, njira imodzi kapena wina ofanana dongosolo mtima, zotupa, kuvulala mutu ndi khosi, ndipo ngakhale sitili kupuma m'mphuno.

Zizindikiro za stasis venous ngati pafupipafupi mutu, chizungulire. Komanso, ululu akhoza timagwira ntchito kwambiri pa kukwaniritsidwa kanthu, kusintha kwa zinthu Link (kutentha, mumlengalenga kuthamanga). Zikavuta, pakhoza kukhala kukomoka, mkhutu ntchito maganizo, mdima, epileptiform khunyu. Kunja, matenda akhoza kusonyeza edema, cyanosis ya nkhope, redness diso.

Chifukwa cha nkhani zimenezi, venous kuchulukana mu mutu pafupifupi konse matenda chachikulu, ndi zambiri comorbidity. Choncho n'kofunika kwa matenda kudziwa zimene, zomwe kudwala ndi pa muzu wa vuto, kuti athe mankhwala mankhwala zolondola. Komanso, n'kofunika kuganizira zinthu zina, zomwe zingachititse venous stasis. Chithandizo Choncho, cholinga chake kulimbana kudwala ndi zomwe zingachititse stagnation. Komabe, kuti magawowa alili angagwiritsidwe ntchito zosiyanasiyana njira, kubwezeretsa yachibadwa magazi.
