Mtsempha wamagazi Popliteal: thunthu, zimachititsa chilumbachi. Kudwala a mtsempha wamagazi ndi popliteal

Popliteal mtsempha wamagazi - chotengera m'malo lalikulu, mwachindunji kupitiriza pansi womwe ndi mtsinje femoral. Yankholo mu zikuchokera kwa mtolo neurovascular, ndi mtsempha homonymous ndi mitsempha tibial. Pa kumbuyo, gawo la fossa popliteal, Vienna mabodza pafupi pamwamba kuposa mtsempha wamagazi ndi; ndipo tibial mitsempha - surfactant kuposa mtsempha.

Location, zimachititsa chilumbachi

Kuyambira pa njira m'munsi kabowo akutsogolera kuti ili pansi mbewa polumembrannoy mtsempha wamagazi popliteal moyandikana pansi zoyambirira fossa popliteal wa femur (ntchafu mwachindunji pamwamba), ndi zina - ndi chipolopolo bondo kapisozi.

ojambula m'munsi mtsempha wamagazi dipatimenti ntchafu minofu. Iwo likulowerera mu malo yopapatiza pakati pa mimba ya minofu gastrocnemius, amene amafotokoza izo. Ndipo polekezera a minofu soleus, sitima lagawidwa kutsogolo ndi kumbuyo mtsempha wamagazi tibial.

Malangizo a mtsempha wamagazi popliteal naye pa ine:
• Mu kumtunda kwa popliteal fossa chotengera uli ndi downwards ndi outwards.
• Popeza m'ma mlingo wa popliteal fossa, mtsempha wamagazi popliteal imatsogoleredwa zayamba vertically downwards.

Nthambi za mtsempha wamagazi ndi popliteal

Panjira pansi mtsempha wamagazi popliteal amapereka angapo nthambi:
• The chapamwamba akulu nthambi.
• The chapamwamba lateral bondo mtsempha wamagazi.
• The chapamwamba medial bondo mtsempha wamagazi.
• Wapakati bondo mtsempha wamagazi.
• m'munsi lateral bondo mtsempha wamagazi.
• wotsika medial bondo mtsempha wamagazi.
• mitsempha Ng'ombe (awiri, kawirikawiri - kwambiri).

Popliteal mtsempha wamagazi aneurysm

Malinga ndi zomwe zachipatala, ichi ndi kutanthauzira zambiri za aneurysms ku periphery kuti: 70% ya aneurysms zotumphukira ali isanafalikire m'dera popliteal. Chifukwa chachikulu cha boma nthendayo ankaona kuti atherosclerosis, chifukwa unali chinthu etiological mu ambiri odwala popliteal mtsempha wamagazi aneurysm.
Popliteal mtsempha wamagazi aneurysm akufotokozera pafupifupi amisinkhu; zikutanthauza zaka pafupifupi zaka 60, ndipo kufala kwa zaka - kuchokera zaka 40 mpaka 90. Amgwirizano chotupa zinalembedwa 50% ya milandu.
N'zochititsa chidwi zambiri matenda umakhuza iwowo.
Chithunzi matenda chimakhala chogwidwa ndi zizindikiro za zotupa ischemic wa malekezero wapotalikira; akhoza kuwonjezeredwa ndi psinjika zizindikiro mitsempha ndi mtsempha (ndi psinjika a aneurysm awo).
zosokonezeka:
• thrombosis wa aneurysm (aneurysmal M'mimbamo);
• aneurysm chophukacho,
• calcification wa aneurysm ya;
• psinjika a mitsempha.
Matenda ntchito:
• Angiography;
• CT.
Zochizira wa ligation kwambiri kawirikawiri anachita a mtsempha wamagazi ndi popliteal mbali ya aneurysm (proximal ndi wapotalikira ake), kenako opaleshoni kulambalala.

thrombosis Popliteal mtsempha wamagazi

Zinanso chinthu mapangidwe kuundana mu mitsempha ndi anagonjetsa mumtima pamwamba pa zotengera, zomwe zimabweretsa zinthu zotsatirazi zikhoza kukhala:
• atherosclerotic madipoziti mu Mitsempha;
• matenda oopsa;
• matenda a shuga;
• zoopsa a linga mtima;
• vasculitis.

mawonetseredwe matenda

Thrombosis a mtsempha wamagazi ndi popliteal popewa zinthu zotsatirazi:
• kupweteka kwambiri nthambi limapezeka zikuchepa. Odwala zambiri kufananiza maonekedwe ake ndi kuphulika. M'tsogolo, ululu zingatenge paroxysmal mu chikhalidwe; ndi twinge kumabweretsa maonekedwe a thukuta pa khungu. Ena easing ululu popanda cholinga limatanthauza kusintha alili pa nthawi.
• blanching wa khungu la nthambi akhudzidwa.
• Kuchepetsa kutentha kwa khungu la nthambi akhudzidwa.
• Maonekedwe a mwendo thickening; malo chikugwirizana ndi malo mlingo thrombus.
• Chepetsani, ndipo kenako - kutha kwa tilinazo wapansi; maonekedwe a paresthesias.
• Kuchepetsa sayenda ya nthambi akhudzidwa. Kenako sayenda akhoza kutayika kwathunthu.
Childs, zizindikiro kukhala pang'onopang'ono, kuyambira maonekedwe a ululu.
Popeza miyeso zokwanira angathe vuto mu mawonekedwe a chilonda. boma amakhala ndi bwino kuti pali kusiyana pakati pa minofu zachilendo ndipo necrotic. Kenako necrotizing gawo mummified.
Koipa-angakuchitireni - izo kachilombo m'dera necrotic. chikhalidwe ichi amawapeza ndi mofulumira osauka hyperthermia, amalembedwa leukocytosis m'magazi ndi kukhalapo kwa anam'peza azingokhala.
