Ukuba kukho i-thrombus enkulu kwi-systemous venous system, isiqhekeza sinokuhlukana nayo, esivame ukuphelisa ukujikeleza kwegazi kwiindawo ezahlukahlukeneyo zenkqubo yokuphefumula. Ngenxa yoko, i-pulmonary embolism iyenzeka - izizathu zeso simo esiyingozi, njengomthetho, ziqulethwe kwii-clots ezinkulu zegazi ezikhoyo kwiimvini ezinzulu.
Ingozi ye-thromboembolism iyanda nini?
Ukubangela ukuphazamiseka kwegazi kunye nokujikeleza kwegazi, kwaye ngoko-ukwakheka kwe-thrombi, kufaka:
- i-myocardial infarction ;
- kuqhuba utyando;
- u bunzima;
- iintsimbi ze-tibia okanye i-femur;
- ukubetha;
- Ukuhlala ixesha elide, ukuthobela ukuphumla kombhede;
- ukungabi nakubunini bemveli kwimveliso ye-inhibitors ye-clotting yegazi;
- izifo ezikhoyo;
- ukwamkelwa kwezibeleko zomlomo.
Isizathu esiphezulu se-thromboembolism yomthamo ubukho be-clot enkulu yegazi (thrombus). Ngokuqhelekileyo itholakala emithanjeni enzulu yemilenze okanye imilenze, kaninzi kangangoko - izandla okanye enye yamagumbi entliziyo.
Iimbangela zokufa kwi-pulmonary artery thromboembolism
Iimeko ezikulo mbuzo ziphela kwisiphumo esibulalayo kwi-20% yamatyala. Oku kubangelwa ukuba emva kokuvalwa komthi we-pulmonary, igatsha elonakalisiweyo liyeke ukuba linikezelwe ngegazi, ngoko ke ligcwele i-oksijini. Ngenxa yoko, i-hypoxia (i-oksijini yindlala) yezitho zangaphakathi ziqala, kukho ukunyuka okubucayi kwingcinezelo yegazi (hypotension), kukho i-tachycardia, i-dyspnea, i- anaphylactic shock . Ukungasebenzi komnye wee-ventricles zenhliziyo, umonakalo kwi-myocardium iyabonwa. Kwiintsuku ezimbalwa, i-infarction yamaphaphu iyakwenzeka, apho i-artery ephazamisayo ikhona.
