I-thrombus ifana nesiporho esizulazula kwimithambo yegazi. Xa umthambo wegazi uvaliwe, inkqubo yokuthutha igazi iya kukhubazeka, kwaye umphumo uya kuba yingozi. Ngaphezu koko, amahlwili egazi anokwenzeka nangaliphi na ixesha nangaliphi na ixesha, nto leyo esongela ubomi nempilo.

Okubangela uloyiko ngakumbi kukuba ama-99% e-thrombi awabonakali okanye aziva, kwaye aya esibhedlele ukuze ahlolwe rhoqo kwiingcali zentliziyo kunye nemithambo yegazi. Oku kwenzeka ngequbuliso ngaphandle kwengxaki.

Kutheni imithambo yegazi ivaliwe?

Kungakhathaliseki ukuba imithambo yegazi ivaliwe phi, kukho "umbulali" oqhelekileyo - i-thrombus.

I-thrombus, eyaziwa ngokuba yi-"blood clot", ivala imijelo yemithambo yegazi kwiindawo ezahlukeneyo zomzimba njengeplagi, nto leyo ebangela ukuba igazi lingangeni kwizitho ezinxulumene noko, nto leyo ebangela ukufa ngequbuliso.

 

1. I-Thrombosis kwimithambo yegazi yengqondo inokukhokelela kwi-cerebral infarction - i-cerebral venous sinus thrombosis

Esi sisifo sohlangothi esingaqhelekanga. Ukuqhekeka kwegazi kule nxalenye yengqondo kuthintela igazi ukuba lingaphumi libuyele entliziyweni. Igazi eligqithisileyo linokungena kwizicubu zengqondo, nto leyo ebangela isifo sohlangothi. Oku kwenzeka ikakhulu kubantu abadala abancinci, abantwana kunye neentsana. Isifo sohlangothi sibeka ubomi esichengeni.

2. I-myocardial infarction yenzeka xa igazi liqhekeka kwimithambo yentliziyo—i-thrombotic stroke

Xa ihlwili legazi lithintela ukuhamba kwegazi ukuya kumthambo osebuchotsheni, iindawo ezithile zengqondo ziqala ukufa. Iimpawu ezilumkisayo zestroke ziquka ubuthathaka ebusweni nasezingalweni kunye nobunzima bokuthetha. Ukuba ucinga ukuba ukhe waba nestroke, kufuneka uphendule ngokukhawuleza, okanye usenokungakwazi ukuthetha okanye ufe umzimba. Okukhona inyangwa ngokukhawuleza, kokukhona amathuba okuba ingqondo iphile kwakhona.

3. I-Pulmonary embolism (PE)

Eli lihlwili legazi elenzeka kwenye indawo lize lihambe ngegazi liye emiphungeni. Ngokuqhelekileyo, livela kumthambo osemlenzeni okanye esinqeni. Lithintela ukuhamba kwegazi ukuya emiphungeni ukuze lingakwazi ukusebenza kakuhle. Likwayonakalisa amanye amalungu omzimba ngokuchaphazela umsebenzi wokunikezelwa kweoksijini emiphungeni. I-pulmonary embolism inokubulala ukuba ihlwili likhulu okanye inani lamahlwili likhulu.
