Popliteal tsinga: anatomi uye kwakaita nzvimbo yacho. Zvokurwara of popliteal tsinga

Popliteal tsinga - mudziyo nani guru, zvakananga kuramba pasi pasi femoral tsinga. It iri Kuronga neurovascular tsapo, pamwe homonymous tsinga uye tibial etsinga. Pakupedzisira, chikamu popliteal fossa, Vienna nhema pedyo pemvura kupfuura tsinga; uye tibial tsinga - zvakawanda surfactant pane midziyo ropa.

Location uye kwakaita nzvimbo yacho

Kutanga pajinga aperture kutungamirira nzira, vari riri pasi polumembrannoy mbeva popliteal tsinga pedyo pasi rokutanga kusvika popliteal fossa pamusoro femur (chidya zvakananga pamusoro), uye zvakare - kuti ibvi Kamudzira deko.

Lower tsinga dhipatimendi contactsGoogle ari pachiuno tsandanyama. Panoparadzana mwoyo munzvimbo yakamanikana nzvimbo pakati dzinokara ari gastrocnemius tsandanyama, izvo kuifukidza. Uye wakati asvika pamucheto soleus tsandanyama, ngarava rakakamurwa mberi uye neshure tibial tsinga.

PeDare popliteal tsinga kwaari pamusoro pangu:
• Mune yokumusoro chikamu popliteal fossa mudziyo ane mirayiridzo downwards uye outwards.
• Sezvo mid-pachiyero popliteal fossa, popliteal tsinga chinotungamirwa substantially vertically pasi.

Mapazi popliteal tsinga

Paaienda pasi popliteal tsinga inopa mapazi:
• The repamusoro tsandanyama mapazi.
• The yokumusoro lateral ibvi tsinga.
• The yokumusoro medial ibvi tsinga.
• The avhareji ibvi tsinga.
• Dzikisa lateral ibvi tsinga.
• Lower medial ibvi tsinga.
• Calf arteries (mbiri, kashoma - zvimwe).

Popliteal tsinga aneurysm

Maererano zvokurapa uwandu, ichi ndicho chinonyanya kakawanda localization ose aneurysms vari arikunze: vanenge 70% kubva peripheral aneurysms vari vemunyika mune popliteal munharaunda. The kukonzera chirwere wehurumende anoonekwa kuti atherosclerosis, sezvo inosimbiswa sechinhu etiological chakaita ruzhinji varwere popliteal tsinga aneurysm.
Popliteal tsinga aneurysm hwapedyo zvinenge zvisinei nezera; zvinoreva makore anenge 60 apfuura, uye kupararira vemazera - kubva 40 kusvika 90 makore. Bilateral lesion wakanyorwa 50% nyaya.
Sezvineiwo kakawanda chirwere ichi chinobata vanhu.
The mufananidzo zvekuchipatara iri hunodzorwa zviratidzo ischemic maronda ari distal kumugumo; inogona kuwedzerwa uye compression tsinga zviratidzo uye tsinga (pamwe compression pamusoro aneurysm yavo).
yematambudziko:
• thrombosis of aneurysm (aneurysmal mhango);
• aneurysm atsamwira;
• calcification of aneurysm;
• compression of etsinga.
Rokuongorora anoshanda:
• Angiography;
• CT.
Nokuti kurapa inonyanyoshandiswa akaita ligation pamusoro popliteal tsinga iri kana parutivi aneurysm (proximal uye distal wake), zvichiteverwa ndavhiyiwa.

Popliteal tsinga thrombosis

Predisposing raivapo nokuumbwa clots vari arteries akakundwa romukati pose midziyo, iro rinoita zvinhu zvinotevera angava:
• atherosclerotic deposits vari pamasvingo midziyo ropa;
• neBP;
• cheshuga;
• kunotevera of vascular rusvingo;
• vasculitis.

zvekuchipatara kuratidzwa

Thrombosis of popliteal tsinga zvinoratidzwa anotevera zvinhu:
• Zvakakomba kurwadziwa rimwe gumbo kuti rinowanika nehasha. Kazhinji varwere enzanisa chitarisiko wake ane rukuru. Mune ramangwana, marwadzo anogona kutora paroxysmal zvakasikwa; uye twinge kunoita kuti chimiro ziya paganda. Vamwe easing kurwadziwa asina chinangwa kunoreva kuvandudza murwere nemamiriro pamusoro nguva.
• blanching pakati ganda njodzi richiripo.
• Kuderedza tembiricha iri paganda njodzi richiripo.
• The pakuonekwa gumbo thickening; ayo nzvimbo rinobatana nzvimbo thrombus chechetere.
• Deredza, uye gare gare - kunyangarika ari nehanya nomusi rutsoka; chimiro paresthesias.
• Kuderedza mufambo pakati njodzi richiripo. Naizvozvo mufambo inogona kurasika zvachose.
Kazhinji, zviratidzo kuva zvishoma nezvishoma, kutanga nechitarisiko marwadzo.
Pasina zvakakwana matanho vanogona kuva kuomesa muchimiro neronda rinonyenga. mamiriro ichi kunoratidzwa pachena kusiyana kuipa uye necrotic tishu. Naizvozvo necrotizing mugove mummified.
The zvakaipisisa zvingaguma zvaitika - nayo chirwere necrotic nharaunda. Izvi mamiriro ezvinhu akanzi ne kukurumidza kutanga hyperthermia, kwakaratidzwa leukocytosis muropa uye kuvapo maronda disintegration.
