Lefu Dego e. vascular stenting

lefu Dego e - lefu le sa tloaelehang hore e qala ka matšoao a letlalo 'me hangata ke bolaeang le ponahalo ea "mpa a hlobaetsang le". O ile a qala ho hlaha ka letlalo la e iphetang khanya pinki. hanyenyane ruruha lekhopho papular, bohareng karolo ea eo ka mor'a nakoana bonahala ea huloa. Ka nako ena ba ba tšoeu. Ba leng teng hangata ka kutu le molaleng letlalo. Mothating ona, lesela fetotsoeng ba lahlile, 'me sebakeng sa bona, liso bulehileng le mophethong e phallang. Libeke tse seng kae hamorao ho ba le mamello e na le bohloko ba bohale le tokelo epigastric sebakeng, feberu, ho hlatsa mali. Litlhaselo tsa bohloko etsahala ka mor'a ho ja. Hoo e ka bang ka mor'a mong le e mong tlhaselo ho na le profuse letšollo. bohloko bo phehellang tsamaya adynamia, ho lahleheloa ke matla a le mokhathala oa mokuli. Bakuli ba ntseng li hōla moruong proteinemiya, hypotension, bilirubinemia. Mali setshwantsho ka kula hangata ho tloaelehile. Ka mor'a hore ponahalo ea matšoao ao a lefu ka 'na etsahala ka mor'a matsatsi a' maloa. Nakong autopsy senotsoeng thrombosis ea methapong le mala necrosis ea intestine le ntle perforation.

lefu Dego e - cutaneous mpeng lefu, eo ho eona lingaka tse hoo e ka bang kamehla ba fana ka itse'ng mafutsana. Lekhopho ka lefu lena hangata bopilwe likarolo tse 'maloa tse nang le mekhahlelo e fapaneng ntshetsopele. Papules na ka khoeli le lebali e e thehoa lilemong tse 0.5.

Ka ho etsa lipatlisiso histological ka dermis ba mokuli ba hlokometse liphetoho tse khōlō tsamaisong ea vascular. Hangata ho na le clots mali, arterioles, endothelial, blockage likepe tse khōlō le tse nyenyane. The collagen dinama tse nyenyane tse ka bophara lijana seo ba anngoeng 'me marako a ba bona ba o ile a re foci ea necrosis fibrinoid. Ka methapong tse nyenyane le hlaha tromboendoteliit. Sebakeng sa collagen likarolo atrophic matla katiloe le e koahetsoeng ka sekala le epidermis e thinned. Ka sedikiso sa lihlopha papular ho na le lijana tsa dilated mali hore a pota-potiloe ke kena ka lenyele lymphohistiocytic. lefu Dego e hapang le lijana kholoanyane teng tebileng ka dermis le subcutaneous dinama tse nyenyane tse. Tshebetso ena le khukhuneloa multiple le degeneration tsa methapo ea mala mali, letlalo le litho tsa ka hare tse ling tse ke tsoana haholo le panarteriit knotty.

Leha lefu Dego le ntshetsopeleng hlobaetsang na le itse'ng futsanehile, ho na le boetse ho na le Maemong a nang le histori e telele hore a ka phekoloa. The phekolo ea lefu lena le o etsoang tsoa le lithibela-mafu, tšelo ea mali, corticosteroid, heparin, livithamine le antihistamines. Ka "a hlobaetsang le mpa" kalafo hoo e ka bang ha e fane ka litholoana tse molemo.

lefu leha e le vascular, haholo-holo batho ba hōlileng, a ka ba le liphello tse tebileng haholo. liphetoho Atherosclerotic ka linako tse ling ama kaofela oona tsamaisong vascular. Ka diso tsa gogoga le carotid methapo, maoto le matsoho, ea bohlokoa restenosis kgothaletswa buuoa kang stenting vascular. Haholo-holo e bontša joalo ka mokhoa o sa e kotsing e phahameng ea infarction myocardial, mafu a ho potoloha ha mali bokong, ho kena-kenana ba leoto mosebetsi, liphetoho trophic.

Stenting contraindicated ka methapo nyane bophara (ka tlase ho tse 2,5 limilimithara), diffuse stenosis (bakeng sa libaka tse khōlō vasoconstriction), renal le matšoafo insufficiency pathologies tsamaisong ea mali coagulation, allergy ho formulations iodine litareng e-nang le (sebediswa ka X-ray lehlakoreng le leng paakanyong).

Pele ke buuoe, o atlehe ena phelang ho etsa lipatlisiso tsa mamello, oa ultrasound ho ithuta intravascular, Doppler ultrasound angiography, ea computed tomography, MRI, EEG, echocardiography, electrocardiography. Pele ke buuoe o etsoang ho tsoa lithethefatsi antiplatelet phekolo e fokotsa menyetla ea mathata thrombotic.

Tšebetso ea stenting vascular o etsoa tlas'a thethebatso ea moo, o ile a etsa ka ho e kgolo mothapo sebaka ka leoto kapa letsoho. Bakeng sa tshebetso radial, femoral kapa mothapo mammary ka sebelisoa. Ngaka o etsa puncture pheriferale mothapo leboteng le kena e le selateng sa (tube, eo ka eona liletsa tse ling li kenngoa).

Thin catheter ho fana ka stent ka lijaneng balonchikom pheriferale ho mothapo e batlang. The spray kgona ke X-ray fapana le moemeli. E a otlolla le stent, e leng e a phuthilweng, mohaho letlooeng tšepe e otlolloa. Tshebetso lohle le hlahellang skrineng. Fixation tsa stent e etsoang ke maikutlo a leboteng mothapo. Ka nako ho ka etsahala ho kenya stents ngata. Ebe lisebelisoa li atoloswa ho tswa lumen sejana sa. opereishene nka ka hora. Mokuli hang ikutloa bohloko le boemong bo sa thabiseng hlaha feela ka nako e ea inflating balonchika. Ka mor'a ho buuoa, mokuli o ile a tloha sepetlele ka matsatsi a 'maloa.
