Bifurcation - is ... lo bifurcation aortic

Igama elithi "bifurcation" lisetyenziswa kwi ncwadi lonyango ixesha elide. Namhlanje siyazi iingqiqo ezininzi eziquka kumafa layo ilizwi.

Intsingiselo yegama elithi

Bifurcation - naliphi uphuphu. Ngaphezu koko, ngokokuqhelekileyo le nto ibonisa ukuba ukwahlukana kwenzeka amalungu ama-2 kunye nama-sangqa efanayo. Kubalulekile ukuba amasebe amabini yehlukana phantsi engile ezifanayo. imizekelo Zintle zingasebenza njengoko bifurcation le carotid kwemithambo, aorta okanye noqhoqhoqho.

Nangona isibakala sokuba eli gama best "babanjwa" ukuba liyeza, sinako ukusisebenzisa kwezinye iindawo. Umzekelo, kwiJografi maxa wambi kukho into enje nje bifurcation umlambo.

Ixabiso le bifurcation amayeza

Ukwahlukana zibe iimpahla zesebe malunga ngokulinganayo ezimbini okanye noqhoqhoqho unalo ixabiso elikhulu. Umzekelo, ukuba bifurcation le aorta ivumela ngesiqhelo kubonelela igazi zombini kwiziphelo asezantsi. Uyavumelana isitya likhulu umzimba womntu ekunene kwaye ekhohlo imithambo femoral. Ngelo xesha nye ivumela tracheal bifurcation oxygen yonikezelo ezimbini ukukhanya ngokulinganayo. Sothi bifurcation - buyinto ebalulekileyo amayeza.

phezu aorta

Bifurcation - ke ukwahlulwa ibe ngamaqela amabini malunga ngokulinganayo. Kwimeko ye aorta, eli gama liye esisetyenziselwe ixesha elide, kodwa enyanisweni ayikho kakhulu ntiyiso. Isibakala sokuba imithambo eziqhelekileyo iliac akukho alingane eyinxalenye aorta kunye namasebe ayo kuphela. Yena uya usihla nkqu ngohlobo impahla encinane obhityileyo.

bifurcation Aortic kwenzeka kwinqanaba empontshwa vertebra IV. Eli nxiwa yenye yezona ezibalulekileyo ngokwemigaqo uzinzo isitya xi blood rhoqo. Into yokuba apha kakhulu kaninzi asike aortic. Ngenxa kwimeko yokuba bifurcation - indawo ethe rhoqo ekucaca ukuba impembelelo lanyuka ukusuka egazini. Kulapha ukuba kufuneka zikhutshwe imithambo ezimbini ezixhaphakileyo iliac. Isiphumo luhlobo olwahlukileyo turbulence igazi kunye neziphumo ekonakaleni ezi kwemali phezu kodonga isitya kwisiza a bifurcation.

Ukongeza kwemithambo le aorta ku ukwabelana kunokwenzeka kukho imiqathango ezigqwesileyo ukuze kwakhiwe umonakalo atherosclerotic. Oku kungenxa yokuba bekhubazekile wenqanawa apho kukho bifurcation Umthambo lezabelo-2, oko kwenzeka kakhulu ngaphezu kuyo nayiphi na enye indawo. Ngokuthe ngcembe ukwandisa ngobukhulu, le nebhodi unga nciphisa ngokubaluleka ukuhamba kwegazi ukuba amalungu zangasese kunye yesiqephu asezantsi.

izilonda bifurcation aortic syndrome

Esi sifo kuyingozi kakhulu. Izisa elininzi ukungakhululeki isigulane kwaye kakhulu kakubi impilo yakhe. Isikakhulu syndrome sikhatshwa bazoyise kuphela ummandla bifurcation aortic ngokwayo, kodwa nakwezinye iindawo. Sithetha kwemithambo iliac kwezintso kokuhlambeleyo. inkqubo Further yezifo kunabela kuphela ikota kwizigulane.

Ezona mpawu ziphambili zale bifurcation syndrome aortic na ukuphazamiseka ejikeleza igazi iimpahla kweqondo ezisezantsi isinqe. Ngako oko, wabonakala ezinkulu kwezonyango aba zinxulumene neendawo. Ukuba sithethe yesiqephu asezantsi, izigulana zintlungu obukhulu ngokwaneleyo. Bathi ebizwa ngokuba yi- claudication uveza.

Ezi mpawu zonyango ichazwa ngokuba, ngenxa ukuba kobuchopho (ukunqongophala igazi kwi-) iintlungu kwaye bumandundu khona. A isici esasenza ye claudication uveza na onaso of bifurcation aortic kukuba le ntlungu hayi yenzelwe na lesiquluba, kwaye ingakumbi esinqeni kunye izihlunu gluteal.

Ethetha wabonakala phezu inxalenye amalungu zangasese, kubalulekile ukuqaphela ukuba ezikhethekileyo namadoda. Bona zibalulwe ukuncipha yobuntu kunye lubuthathaka ulwakhiwo ukuya induku. Uxilongo syndrome bifurcation aortic sisilonda esidumbileyoesingaphakathi ngokusekelwe ukuncipha kwegazi kwi iimpahla kweqondo asezantsi, oko kumiselwa ngokulinganisa BP kwi ubugcisa kunye namandla lencinibakazi ukubetha. Ukuze uqinisekise uxilongo olwenziwe sfigmo- okanye rheovasography. Ngaphandle impatho ekhethekileyo ubungqongqo sifo yandiswa kwemali.

Isahlulo kwemithambo carotid

Bifurcation - into uphawu hayi nje aorta, kodwa kwemithambo carotid. inkululo yayo kwenzeka kwinqanaba ungqameko olungezantsi intlala lengqula. Kulo mzekelo, imithambo carotid ngasekunene nangasekhohlo, nangona umahluko omkhulu kwizinto Ubude kwabo site, yahlulelwe kwii amasebe yangaphandle nangaphakathi apha.

Njengoko kunjalo kunye aorta, a bifurcation onjalo - indawo awandisiweyo ingozi. Kwakhona ukuze ukuphuhlisa aneurysms kunye nezinye iinkqubo zophendlo lwezifo ngenxa yokwanda ukungakhuseleki kwi ukuhamba kwegazi kwindawo benqanawa. Umthambo ulwelo mncinci ububanzi bayo nama-2 umphinda-xa kuthelekiswa "ukhokho 'yakhe. Ngenxa yoko, oko endaweni bifurcations ziye i trombotizatsii nengozi kunye embolization. Ngenxa yesi sizathu, kwimeko kokuvela oogqirha bezonyango ehambelana ngokuyintloko ehlola isithuba division kwemithambo, uze emva koko kwiziqephu eseleyo kwayo.

Bifurcation indlela ephambili womoya

Uqhoqhoqho umzimba umngxuma nenoxanduva lokuqhuba umoya bronchi, uze emva koko emiphungeni. Xa isakhiwo waso inani elikhulu (ukuya kwi-26) amakhonkco cartilaginous ezithintela uqhoqhoqho kudambe.

tracheal bifurcation kwenzeka ekupheleni esisemantla V vertebra thoracic. Xa abantwana, engaphezulwana nje kancinane. Ngaphezu level bifurcation inspiratory kwatshintsha yi malunga 2-3 cm ezantsi. Apha iphecana ezinkulu aeriferous yohlulwe ngasekunene nangasekhohlo bronchi ephambili. Kwixesha elizayo, ukuba uwaphule ngokuphindaphindiweyo. Intsingiselo olusisiseko bifurcation tracheal lo ngokwahlula enye indlela enkulu womoya zibe ezincinane 2. Kuyimfuneko ukuba stock ioksijini ngqo zombini nemiphunga. Le bifurcation ye uqhoqhoqho lwenziwa kwi-engile nama-70 ^o. Icandelo esebenzayo Inhalation ukuze ngandlel ukwandisa.
