I-Thrombosis iyindlela evamile yomzimba yokujiyisa igazi.Ngaphandle kwe-thrombus, abantu abaningi bangafa "ngenxa yokulahlekelwa igazi eliningi".
Ngamunye wethu ulimele futhi wopha, njengenxeba elincane emzimbeni, elizophuma ngokushesha.Kodwa umzimba womuntu uyozivikela.Ukuze kuvinjelwe ukopha kuze kube sekufeni, igazi liyojiya kancane kancane endaweni yokopha, okungukuthi, igazi liyokwakha i-thrombus emithanjeni yegazi eyonakele.Ngale ndlela, ngeke kusaba ukopha.
Lapho ukopha kuyeka, umzimba wethu uzoncibilika kancane kancane i-thrombus, okuvumela igazi ukuba lijikeleze futhi.
Indlela ekhiqiza i-thrombus ibizwa ngokuthi i-coagulation system;indlela esusa i-thrombus ibizwa ngokuthi i-fibrinolytic system.Uma umthambo wegazi sewonakele emzimbeni womuntu, uhlelo lwe-coagulation lusebenza ngokushesha ukuze kuvinjelwe ukopha okuqhubekayo;uma kwenzeka i-thrombus, uhlelo lwe-fibrinolytic oluqeda i-thrombus luzosebenza ukuze luhlakaze ihlule legazi.
Lezi zinhlelo zombili zinokulinganisela okuguquguqukayo, okuqinisekisa ukuthi igazi alijiki futhi alophi kakhulu.
Kodwa-ke, izifo eziningi zizoholela ekusebenzeni okungavamile kwesistimu ye-coagulation, kanye nokulimala kwe-intima yomkhumbi wegazi, futhi i-blood stasis izokwenza uhlelo lwe-fibrinolytic sephuze kakhulu noma lunganele ukuhlakaza i-thrombus.
Isibonelo, ku-acute myocardial infarction, kune-thrombosis emithanjeni yegazi yenhliziyo.Isimo semithambo yegazi sibi kakhulu, kukhona ukulimala okuhlukahlukene kwe-intima, futhi kukhona i-stenosis, ehambisana nokuma kokugeleza kwegazi, ayikho indlela yokuhlakaza i-thrombus, futhi i-thrombus izoba nkulu futhi ibe nkulu.
Isibonelo, kubantu asebelele isikhathi eside, ukugeleza kwegazi lendawo emilenzeni kuhamba kancane, i-intima yemithambo yegazi yonakalisiwe, futhi kwakheka i-thrombus.I-thrombus izoqhubeka nokuncibilika, kodwa ijubane lokuqedwa alisheshi ngokwanele, ingase iwe, igeleze ibuyele emithanjeni yamaphaphu ngohlelo lwegazi, ibambeke emithanjeni yamaphaphu, futhi ibangele i-pulmonary embolism, nayo ebulalayo.
Ngalesi sikhathi, ukuze kuqinisekiswe ukuphepha kweziguli, kuyadingeka ukwenza ngokuzenzakalelayo i-thrombolysis futhi ujove izidakamizwa ezisetshenziselwa ukukhuthaza i-thrombolysis, njenge "urokinase".Kodwa-ke, i-thrombolysis ngokuvamile idinga ukwenziwa phakathi nesikhathi esifushane se-thrombosis, njengaphakathi kwamahora angu-6.Uma kuthatha isikhathi eside, ngeke kuncibilike.Uma ukwandisa ukusetshenziswa kwezidakamizwa ze-thrombolytic ngalesi sikhathi, kungase kubangele ukopha kwezinye izingxenye zomzimba.
I-thrombus ayikwazi ukuncibilika.Uma ingavimbekile ngokuphelele, "i-stent" ingasetshenziswa "ukudonsa ukuvula" imithambo yegazi evinjiwe ukuqinisekisa ukugeleza kwegazi okushelelayo.
Kodwa-ke, uma umkhumbi wegazi uvinjelwe isikhathi eside, kuzodala i-ischemic necrosis yezakhiwo ezibalulekile zezicubu.Ngalesi sikhathi, kuphela "ngokudlula" eminye imithambo yegazi ingangeniswa "ukunisela" lesi siqeshana sezicubu esilahlekelwe ukutholakala kwegazi.
Ukopha kanye ne-coagulation, i-thrombosis kanye ne-thrombolysis, ibhalansi ethambile egcina imisebenzi yomzimba.Akugcini lapho, kunezilinganiso eziningi ezihlakaniphile emzimbeni womuntu, njengenzwa ezwelayo kanye ne-vagus nerve, egcina ukujabula kwabantu ngaphandle kokujabula kakhulu;i-insulin ne-glucagon ilawula ibhalansi kashukela wegazi labantu;I-calcitonin ne-hormone ye-parathyroid ilawula ushukela wegazi labantu.
