Iinaliti ze-AV Fistila kwi-dialysis: Iindidi, izibonelelo, nokubaluleka

I-Arteriovenous (AV) Inale yeFistulasisixhobo esibalulekileyo esisetyenziswa kwi-hemodialysis kwizigulana ezinokuphumelela kwizintso. Idlala indima ephambili ekufikeleleni kwigazi lokususwa ngokufanelekileyo kweetyhefu kunye nokugcwala okugqithisileyo emzimbeni. I-AV Fistais yenziwa ngokuqinisa ngokuqhagamshela i-artery kwi-vein, ibonelela ngendawo yokufikelela eyomeleleyo yedayisi. Inaliti esetyenziselwa ukufikelela kule ndawo kufuneka ithembeke, ilungele kwaye ilungele. Kukho iintlobo ezahlukeneyo zeenaliti ze-AV zeFistila, kunye neendidi ezahlukeneyo zefistula, ezinjenge-bististalic fistalic, ezifumana iimfuno ezahlukeneyo zesigulana.

WUkuxoxa nge-henInale ye-hemodialysis fistla, Zimbini iintlobo eziphambili eziqhelekileyo ezenziwa ngokuxhomekeka kwimpilo ye-vascular kaguli kunye neengcebiso zonyango:

I-Brachiocephalic fista: Olu hlobo lwefistila lusenziwa ngokudibanisa ubugcisa be-brachial kwi-cein ye-binjilic, ihlala ingalo ephezulu. Kuyaziwa ngokubonelela ngenqanawa enkulu yedayisi, evumela ukuhamba kwegazi elingcono kwaye kunokuxhasa amaxabiso aphezulu okuqala kwesilayidi. I-Brachioceli fistal isetyenziswa rhoqo kwizigulana ezinemithambo engalo yengalo ephantsi ayifanelekanga kwi-fistala.

I-radiocephalic fista: idla ngokubizwa ngokuba "ngumgangatho wegolide" ye-fistilas, olu hlobo lubandakanya ubugcisa obuqu kwi-bidalic vein, ngokwesiqhelo esinqeni. Ngelixa kunokuthatha ixesha elide ukuba ivuthiwe kwaye inokuba negazi elincinci elincinci xa lithelekiswa neFrachiocelal Fistali, ibonelela ngeenzuzo njengokugcina ithambo le-proximal ukuze ifumaneke.

Izibonelelo zokusebenzisa inaliti ye-AV Fistale
Inale ye-AV Fistula ibonelela ngezibonelelo ezininzi kunyango lwedayiri, ngakumbi xa kuthelekiswa nezinye izixhobo zokufikelela ze-vascular ezifana ne-catheters ye-vehees ephakathi okanye amagqwirha aphambili. Ezinye zeenzuzo eziphambili zibandakanya:

Ukuqina: I-AV Fistais yaziwa ngokuqina kunye nokusebenza kwexesha elide. Nje ukuba ukhulisiwe, i-AV Fista inokuthi ihlale iminyaka eliqela, esenza isisombululo esisigxina sithelekiswa nezinye iintlobo zokufikelela kwe-vascular.

Umngcipheko ophantsi wosulelo: I-fistilas inomngcipheko ophantsi wosulelo xa kuthelekiswa ne-Catheters ephakathi, ngokungathi akukho nto ingaphandle ngaphakathi komzimba enokusebenzela njengomhlaba wokuzala weentsholongwane. Ukusetyenziswa kweenaliti ze-Av fistile ze-festile zinciphisa umngcipheko wokosuleleka.

Ukuhamba kwegazi okungcono: I-Av Fistais ibonelela ngokuhamba kwegazi elingcono xa kuthelekiswa nee-catheters okanye iigrafti. Oku kuhamba kwegazi okuphezulu kwegazi kuqinisekisa ubuchwephesha obusebenza ngakumbi bokucoca i-sherasis, ukuphucula ukususwa kweetyhefu kunye nolwelo olugqithisileyo kwigazi.

I-clotting encinci: I-AV Fistais ayinabuchwephesha kwi-clotting kune-graftic ye-switveetic okanye ii-catheters. Ngenxa yokuba i-fistila isebenzisa imithambo yegazi yesigulana, umzimba unokubakho kangako kwiindlela ezinqabileyo, ezinokuphazamisa idayisi.

Ukugcina iziqhulo eziphambili: I-AV Fistilais Sustilais Gcina i-Veins enkulu, ebaluleke kakhulu kwizigulana ezinokufuna i-dialysis. Ukugcina le ntaba kuqinisekisa ukuba iindawo zokufikelela kwixesha elizayo zokuhlala zihlala zilungile.

INKQUBO YOKUGQIBELA: INKQUBO YOKUDALWA KWE-AV Fistal yinkqubo yokuphuma, intsingiselo ayifuni ukuhlala isibhedlele. Izigulana zihlala zigodukamini kwangaloo mini, kwaye kanye nje i-fistla ivele, inokubuyela kwiiseshoni ezilinganayo ngaphandle kwesidingo solo utyando olongezelelweyo.

I-shanghai yeQela leQela: Umthengisi othembekileyo weIzixhobo zonyango
Xa kuziwa ekufumaneni iinaliti ezisemgangathweni eziphezulu ze-AV kunye nezinye izixhobo zonyango, i-shangstand yeqela leqela le-shangshei limi ngaphandle njengomthengisi othembekileyo nothembekileyo. Ngeminyaka yamava kwicandelo lezonyango, babonelela ngoluhlu olubanzi lweemveliso zonyango, kubandakanya izixhobo zokungena ze-vascular, zonke zenziwe ukuba zifezekise imigangatho yehlabathi. Iinaliti zabo ze-Av Fistula zenzelwe ukuchaneka, ukhuseleko, kunye nokuthuthuzelwa ngomonde, zinceda oonogada bezempilo ukuhambisa unyango olufanelekileyo nolususekileyo. Ngeziqinisekiso ezinjenge-EC, ISO13485, imvume ye-FDA, iQela leQela leShanghai iqinisekisa ukuthembeka kunye nomgangatho weemveliso zayo, ekukhonzeni abathengi emhlabeni jikelele.

Ukuqukumbela, iinaliti zeFistila Fistula ziyinxalenye ebalulekileyo yonyango lwedayili, ukubonelela ngeendlela eziqinisekileyo, ezikhuselekileyo nefanelekileyo zokufikelela kwigazi. Ngezibonelelo zokuhamba kwegazi elingcono, ukuncitshiswa komngcipheko wokosuleleka, kunye nokusebenza kwexesha elide, i-av fistis ithandwayoUkufikelela kwi-vascularkwizigulana ezininzi zedayisi. I-Shanghai yeQela leQela, ngokuzibophelela kwakhe kumgangatho kunye nokuSebenza, ibonelela ngeendlela eziphezulu ze-AV Fisti fistla Fisti fistle ezihlangabezana neemfuno eziluqilima zononophelo.
