Yamafutha

Yegazi, phakathi kwezinye izifo iimpahla yegazi peripheral has indawo phambili.

Kaninzi, ngenxa yokugula ichaphazela amadoda amadala ngaphezu kweminyaka engamashumi amane. Yamafutha ntonje unobangela ischemia kakhulu, umgwebe izigulane ukuba isohlwayo buhlungu kakhulu. Noko ke, izigulane ezininzi banokulahlekelwa kukuba nako kwabo ukusebenza. Isikakhulu ephawulwe yamafutha ezincinane lomzimba elisezantsi. Le nkqubo yenzelwe kule aorta. Ukongeza, kaninzi sifo sichaphazela kwemithambo srednekalibernye - femoral kunye popliteal.

Lokutshabalalisa yamafutha of kweqondo ephantsi ezinxulumene iimeko ezifanayo etiological neendlela pathogenetic engabangela isifo nezinye zalapha.

Iinguqu ezinkulu kuvandlakanywa lipoidoza nakujoliso olutsha wedini. Oku kuphakamisa inyama entsha nokuqina. Ivuthwa, oko kukhokelela ekukhuleni umonakalo ezinezikhondo. Ezi ukunqamka okunokwenzeka zokwakheka kwenzeka fibrin kunye zegazi egazi. Tibusiso lipid yokuzuza evusa a ukuphazamiseka nokuhamba kwegazi kwi umonakalo. necrosis sabo sabangela, nayo, ukwakheka atheroma. Eziqulathwe mass atheromatous ngokuwa nemingxuma yabo mithambo benqanawa. Eqwengiweyo kwicala distal, ukuba bandiqumbise Embolism.

Ngelo xesha, ekucaca ukuba utshintsho nezihlunu umonakalo kwiinkalo imicu enwebekayo baye ukuphela, baqale ukubeka iityuwa calcium. Ngoko yamafutha ophuma kwinqanaba lokugqibela.

Ngexesha lonke sifo ezine zezigaba.

Yamafutha iminyaka eliqela ukuze aphuhlise ngaphandle naziphi na iimpawu. Noko ke, ukususela ekuqaleni iimpawu zonyango ngokufuthi siqhuba ngokukhawuleza kakhulu.

Kwezinye iimeko, ngenxa acceding thrombosis, obubonakala sifo ebonakala ngokukhawuleza. Imbali njalo izigulane lwegazi, imbali engabalulekanga, angina, isifo seswekile, ukuphazamiseka yegazi zobuchopho.

Iimpawu zesi sifo kufuneka zihlelwe claudication ngakanye, nto leyo ebonakalisa efakwe kwemisipha ithole. Mizwa ngokuqhelekileyo zenzeke ngexesha ukuhamba, kwaye shwaka emva luphumlo elifutshane.

amanxeba Atherosclerotic kwemithambo iliac kunye yesiphelo isabelo aorta ezenza iintlungu esiswini yenzelwe nje kuphela shins, kodwa izihlunu ethangeni gluteal kwakunye kwindawo empontshwa. Ukuqiniswa kwe claudication uveza waphawula ngexesha ummango okanye kwizinyuko.

Iimpawu zazo idla ngokuba zithathwa ingqiqo chilliness, ukukhulisa imilenze uvakalelo ebandayo, baphelelwe iinyawo. Ngenxa ischemia kukho utshintsho umbala kweqondo asezantsi. Kuphuhliso Ekuqaleni sifo, baya kuba luthuthu ngebala. Ekuhambeni kwesi sifo eluswini iminwe kunye iinyawo zibe nemfusa-cyanotic.

nokuphazamiseka Trophic ukuphazamisa ukukhula izikhonkwane negalelo ukuwa kweenwele.

Ukuqhubela phambili kwesifo uphawuleka utshintsho sisilonda-necrotic emzimbeni elithambileyo kwimimandla distal ye imilenze abachaphazelekayo. Ziphawuleka nokudumba nesingxi hyperemia. Aortoiliac occlusion isabelo luphawu uphawu yokungabi okubangelwa akaphilanga, nokuhamba kwegazi.

Uviwo lwezigulane ngokufuthi utyhila yoma okanye umonakalo izihlunu kwi eziphelweni asezantsi.

Kudla kukho ekubulaleni kwicandelo femoropopliteal, nto leyo kubonakala kungekho nayiphi na ekuphuculeni phezu imithambo yokumisa okanye ukuba umthambo popliteal ukusuka kwindawo imvelaphi kwemithambo enzulu femoral.

Indlela ephambili kokuxilongwa uthathwa angiography. Le ndlela ivumela ukuchonga ubungakanani kunye zalapha zenkqubo lwezidumbu, umgangatho izilonda semithambo, ebonakala ukujikeleziswa akananto, kwakunye ukuvavanya imeko yokumpompoza kwegazi channel distal.
