Umthambo Popliteal: nokwakheka sendawo. Pathology we Umthambo popliteal

Umthambo Popliteal - esibuthakathaka kunalokho enkulu, Ngokuqhubeka ngqo phansi ukuba umthambo femoral. Ihlala lichaza ekwakheni lenqwaba neurovascular, nge vein homonymous futhi emsipheni tibial. Ngesikhathi misa, ingxenye fossa popliteal, Vienna amanga eduze kwamanzi ngaphandle Umthambo; futhi izinzwa tibial - surfactant ezingaphezu kuka imithambo yegazi.

Indawo kanye nesimo sendawo

Nasiqala isiteshi beso ephansi ehola, kokuba itholakala ngaphansi polumembrannoy amagundane Umthambo popliteal eduze phansi ngowokuqala fossa popliteal ka kunawo wonke (ethangeni ngqo ebusweni), futhi eminye - kuya igobolondo amadolo capsule.

Lower oxhumana umnyango Umthambo le imisipha ethangeni. It lingena endaweni ewumngcingo phakathi khaba imisipha gastrocnemius, okuyinto ukufihla. Kwathi sebefike emaphethelweni imisipha soleus, umkhumbi sehlukaniswe front futhi bakhulise tibial Umthambo.

Isiqondiso Umthambo popliteal kuye phezu kwami:
• Esikhathini engxenyeni engenhla popliteal fossa isitsha has a isiqondiso liye phansi bese phandle.
• Kusukela maphakathi nawo-ezingeni fossa popliteal, Umthambo popliteal iqondiswa kakhulu thwi phansi.

Amagatsha Umthambo popliteal

Endleleni phansi Umthambo popliteal unika amagatsha amaningana:
• I engenhla amagatsha kwemisipha.
• I engenhla lateral amadolo Umthambo.
• I engenhla medial amadolo Umthambo.
• Isilinganiso amadolo Umthambo.
• Yehlisa lateral amadolo Umthambo.
• Lower medial amadolo Umthambo.
• Inkonyane imithambo (ezimbili, akuvamile - ngaphezulu).

Popliteal Umthambo isifo sokuvuvukala kwemithambo

Ngokwezibalo yezokwelapha, lena kwasendaweni njalo iningi aneurysms e azungeze:-70% aneurysms neuropathy kuthiwa isebenze endaweni popliteal. Isizathu esikhulu isimo isifo ubhekwa isifo sokuqina kwemithambo yegazi, ngoba Kumiswa njengenhlangano isici etiological iningi iziguli popliteal Umthambo useshonile.
Popliteal Umthambo isifo sokuvuvukala kwemithambo eba cishe kungakhathaliseki ubudala; Kusho ubudala cishe engu-60 edlule, futhi ukusabalala ubudala - kusukela eminyakeni engu-40 kuya kwangu-90. lesion Bilateral kulotshwe 50% amacala.
Kuyaphawuleka kaningi lesi sifo sithinta abantu.
Isithombe emitholampilo ubuswa izimpawu of izilonda ischemic of emkhawulweni distal; kungenziwa wanezela futhi kokucindezelwa izimpawu nerve futhi umthambo (nge zlib of useshonile zabo).
yezinkinga:
• thrombosis we useshonile (aneurysmal ingaphakathi);
• isifo sokuvuvukala kwemithambo ukudabuka;
• calcification we useshonile;
• kokucindezelwa we emsipheni.
Ukuxilonga isicelo:
• Angiography;
• CT.
Ukuze ekwelapheni Ligation njalo lwenziwa iningi Umthambo popliteal ku zombili useshonile (proximal futhi distal wakhe), kulandele ukuhlinzwa dlula.

Popliteal Umthambo thrombosis

Ungalokothi uphuze isici kumiswa amahlule e imithambo linqotshiwe engaphakathi imithambo, elibangela lezi zinto ezilandelayo kungase kube:
• ezifakwa atherosclerotic ku Imithambo yegazi;
• umfutho wegazi ophakeme;
• isifo sikashukela;
• uhlukunyezwe odongeni semithambo;
• vasculitis.

ukubonakaliswa emitholampilo

Thrombosis we Umthambo popliteal kuboniswa izici ezilandelayo:
• ubuhlungu ezinamandla umlenze evelayo ngqo. Iziguli kaningi ukuqhathanisa ukubukeka kwakhe nge bang. Esikhathini esizayo, ubuhlungu kungathatha paroxysmal ngokwemvelo; futhi ulahlwa kuholela ukubukeka umjuluko esikhumbeni. Ukudamba ubuhlungu kungekho inhloso kusho ukuthuthukisa isimo lesiguli ngokuhamba kwesikhathi.
• blanching kwesikhumba esitho ethintekile.
• Yehlisa izinga lokushisa kwe-isikhumba esitho ethintekile.
• Ukubukeka the ukuqina umlenze; indawo yayo kuvumelana indawo ezingeni thrombus.
• Nciphisa, futhi kamuva - ukunyamalala ukuzwela ku nonyawo; ukubukeka paresthesias.
• Linganisa ukuhamba esitho ethintekile. Ngemva kwalokho ukuhamba ingakulahlekela ngokuphelele.
Ngokuvamile, izimpawu kancane kancane, eziqala ukubukeka ubuhlungu.
In the ukungabikho izinyathelo ezanele ingakha inkinga ngesimo esibhibhayo. Lesi simo libhekene kube nomehluko ocacile phakathi kwezicubu evamile futhi necrotic. Ngemva kwalokho necrotizing ingxenye mummified.
I zihambe - ke itheleleke endaweni necrotic. Lesi simo kuthiwa i ngomshini ngokushesha ukuthuthukisa komzimba okukhulu, imakwe leukocytosis egazini futhi khona lokubola esidalwa yizilonda emathunjini sibe.
