Isifo sokuqina kwemithambo yegazi

Isifo sokuqina kwemithambo yegazi, phakathi kwezinye izifo imithambo yegazi neuropathy it has a isikhundla okuholela.

Ngokuvamile, ukugula kuthinta amadoda amadala kuka engamashumi amane. ngokuvamile Isifo sokuqina kwemithambo yegazi siyimbangela ischemia ezinzima, ligxeke iziguli buhlungu jeziso kakhulu. Nokho, iziguli eziningi bangalahlekelwa ukukwazi kwabo ukusebenza. Isikhathi esiningi imakwe isifo sokuqina kwemithambo yegazi kanye nekufundzisa tinhlavu letincane esitho imithambo. Inqubo ingase isebenze le-aorta. Ngaphezu kwalokho, ngokuvamile lesi sifo sihlasela Umthambo srednekalibernye - femoral futhi popliteal.

Abhubhisa atherosclerosis ka emikhawulweni engezansi ehambisana ne-izici ezifanayo etiological netindlela pathogenetic ezibanga izifo nezinye kwasendaweni.

Izinguquko ezinkulu kuyagcinwa e lipoidoza foci selilonke. Lokhu kuphakamisa izicubu fresh zezinzwa. Ukukhula, kuholela ekwandeni zingcwecwe fibrous. Lezi zokwakheka subsidence kwenzeka fibrin futhi platelet amahlule. Okuchichimayo lipid ekuqongeleleni kuphakamisa ukuphazamiseka kwegazi kulezi zingcwecwe. necrosis yabo okubangelwa yena, ukwakheka atheroma. Kuqukethwe izimbotshana yabo mass atheromatous iwela inesikhala bomkhumbi. Torn ohlangothini distal, bangakwazi avuse embolism.

Ngesikhathi esifanayo, wadalula yezinguquko izicubu zingcwecwe ezindaweni imicu enwebekayo yezicubu ibhekane ukonakala, baqala ukubeka calcium nosawoti. Ngakho-atherosclerosis okuphuma esigabeni sokugcina.

Phakathi nayo yonke lesi sifo izigaba ezine.

Isifo sokuqina kwemithambo yegazi iminyaka eminingi angagcina ngaphandle izimpawu. Nokho, kusukela lapho kuqala izimpawu zokwelashwa ngokuvamile iqhubeka ngokushesha okukhulu.

Kwezinye izimo, ngenxa yokuthi ukukhokha imali eningi thrombosis, ukubonakaliswa isifo esibonakala ngokuzumayo. Umlando ngokuvamile in iziguli umfutho wegazi ophakeme, umlando esivimba amanzi, angina, isifo sikashukela, izinkinga kwegazi ebuchosheni.

I izimpawu zesifo kumele labizwa ngokuthi claudication ngakanye, okuyinto kubonakala soreness kwemisipha ithole. Emizweni zivamise ukwenzeka ngesikhathi ehamba, zinyamalale emva ukuphumula iDemo.

izilonda Atherosclerotic kwemithambo yegazi iliac futhi ingxenye ukuphela kwe-besisu aorta avuse ubuhlungu ezindaweni ezithile, hhayi nje kuphela shins, kodwa imisipha ethangeni gluteal kanye endaweni lumbar. Ukuqiniswa ka claudication ngakanye waphawula phakathi ekukhuphukeni noma izitebhisi.

izimpawu ejwayelekile abhekwa umuzwa lokubaba, ephakamisela imilenze ukuzwela amakhaza, izinyawo ungenayo. Ngenxa ischemia kukhona ushintsho umbala wemikhawulo aphansi. Ngo ukuthuthukiswa okuqala e-izifo, iyaphaphatheka ngombala. Ngokuhamba isifo esikhumbeni iminwe nezinyawo babe purple-cyanotic.

iziyaluyalu trophic ukuphazamisa ukukhula izinzipho neqhaza nezinwele.

Ukuqhubeka kwesifo libhekene izinguquko esidalwa yizilonda emathunjini sibe-necrotic kwezicubu ezithambile izingxenye distal yezingalo nemilenze abathintekayo. Kuyaqapheleka edema kanye hyperemia stop. Aortoiliac occlusion ingxenye kuwuphawu nobuntu ubuthakathaka kubangelwa ukugula ngengqondo kwegazi.

Ukuhlola iziguli ngokuvamile kwembula yoma noma ukuzaca imisipha e wemikhawulo aphansi.

Ngokuvamile kukhona Ukunqotshwa kwe-ingxenye femoropopliteal, njengoba kubonakala khona kwanoma isiphi yezwakala ku imithambo we esitobhini noma Umthambo popliteal kusukela iphuzu umsuka Umthambo ezijulile femoral.

Indlela eyinhloko uphethwe kubhekwa angiography. Le ndlela ivumela ukuhlonza khona ngezinga elithile futhi kwasendaweni yenqubo sokugembula, lizinga izilonda semithambo, ebonakala kwegazi eseduze, kanye ukuhlola isimo ukugeleza kwegazi isiteshi distal.
