Ukuvalelwa kwegazi okukhoyo - izintso

Ukuchaphazeleka okubonakalayo kwezintso ngesiquphe, kukuvaleka ngamandla komthambo ohambisa igazi kwizintso.

Izintso zifuna igazi elifanelekileyo. Umthambo ophambili wezintso ubizwa ngokuba ngumthambo wezintso. Ukuhamba kwegazi okuncitshisiweyo ngomthambo wezintso kunokwenzakalisa ukusebenza kwezintso. Ukuvaleka okupheleleyo kokuhamba kwegazi kwizintso kunokubangela ukusilela kwezintso ngokusisigxina.

Ukuchaphazeleka komthambo we-renal umthambo kunokwenzeka emva kokulimala okanye ukwenzakala kwisisu, ecaleni, okanye ngasemva. Amahlwili egazi ahamba egazini (emboli) anokuhlala kwimithambo yegazi.Amacwecwe e-plaque asezindongeni zemithambo anokuvela (eyedwa okanye ngexesha lenkqubo). Le nkunkuma inokuthintela umthambo omkhulu wezintso okanye enye yeenqanawa ezincinci.

Umngcipheko wee-renal artery blockages ukwanda kubantu abaneengxaki ezithile zentliziyo, ezenza ukuba babenakho ukwenza amahlwili egazi. Oku kubandakanya i-mitral stenosis kunye ne-atrial fibrillation.

Ukunciphisa umthambo we-renal kuthiwa yi-renal artery stenosis. Le meko inyusa umngcipheko wokucinywa ngequbuliso.

Ungangabinazo iimpawu xa enye intso ingasebenzi kuba intso yesibini inokulicoca igazi. Nangona kunjalo, uxinzelelo lwegazi oluphezulu (uxinzelelo lwegazi) lunokuza ngesiquphe kwaye kube nzima ukululawula.

Ukuba ezinye izintso zakho azisebenzi ngokupheleleyo, ukuvalwa komthambo wezintso kunokubangela iimpawu zokungaphumeleli kwezintso. Ezinye iimpawu zokuchaphazeleka okubonakalayo komthambo we-renal kubandakanya:

• Intlungu zesisu
• Ukuhla ngesiquphe kwimveliso yomchamo
• Umqolo obuhlungu
• Igazi kumchamo
• Intlungu yeflank okanye iintlungu ecaleni
• Iimpawu zoxinzelelo lwegazi oluphezulu njengentloko ebuhlungu, utshintsho kumbono kunye nokudumba

Qaphela: Akunakubakho zintlungu. Intlungu, ukuba ikho, ihlala ikhula ngesiquphe.

Umboneleli wokhathalelo lwempilo ngekhe akwazi ukuchonga ingxaki ngovavanyo nje ngaphandle kokuba usebenze ukusilela kwezintso.

Uvavanyo onokulufuna lubandakanya:

• I-Duplex Doppler ultrasound yovavanyo lwee-artery ze-renal ukuvavanya ukuhamba kwegazi
• I-MRI yemithambo yezintso, enokubonisa ukungabikho kokuhamba kwegazi kwizintso ezichaphazelekayo
• I-arteriography ye-renal ibonisa eyona ndawo yokuthintela
• I-Ultrasound yezintso ukujonga ubungakanani bezintso

Rhoqo, abantu abaludingi unyango. Amahlwili egazi angangcono ngokwabo ekuhambeni kwexesha.

Unokuba nonyango lokuvula umthambo ukuba ukuvaleka kufunyenwe ngokukhawuleza okanye kuchaphazela kuphela ukusebenza kwezintso. Unyango lokuvula umthambo lungabandakanya:

• Amachiza onyibilikisa amahlwili (thrombolytics)
• Amayeza athintela igazi ekunqandeni (ii-anticoagulants), ezinjengewarfarin (Coumadin)
• Ukulungiswa kotyando lwe-artery renal
• Ukufakwa kwetyhubhu (i-catheter) kwimithambo ye-renal ukuvula ukuvalwa

Unokufuna i-dialysis yexeshana ukunyanga ukusilela kwezintso. Amayeza okwehlisa i-cholesterol anokufuneka ukuba ukubhloka kubangelwe kukuqina kwethambeka kwimithambo.

Umonakalo obangelwe kukuvalelwa komzimba okungamanyala kunokuhamba. Nangona kunjalo, kwiimeko ezininzi, zihlala zisisigxina.

Ukuba sinye kuphela isifo sentso esichaphazelekayo, izintso ezisempilweni zinokuthatha indawo yokucoca igazi zivelise umchamo. Ukuba unesifo esinye kuphela sezintso, ukuvalelwa komzimba okungahambelaniyo kukhokelela kukusilela kwezintso. Oku kunokukhula kungaphumeleli kwezintso.

Iingxaki zinokubandakanya:

• Ukungaphumeleli kwezintso
• Isifo sezintso esinganyangekiyo
• Igazi elonyukayo
• Uxinzelelo lwegazi

Fowunela umnikezeli wakho ukuba:

• Uyeke ukuvelisa umchamo
• Uziva ngesiquphe, iintlungu eziqatha ngasemva, iflank, okanye isisu.

Fumana uncedo lwezonyango olungxamisekileyo kwangoko ukuba uneempawu zokungabikho komzimba kwaye unentso enye kuphela esebenzayo.

Kwiimeko ezininzi, ukuphazamiseka akunakukhuselwa. Eyona ndlela ibalulekileyo yokunciphisa umngcipheko kukuyeka ukutshaya.

Abantu abasemngciphekweni wokuphuhliswa kwamahlwili egazi kusenokufuneka bathathe amayeza okulwa amahlwili. Ukuthatha amanyathelo okulawula izifo ezinxulumene ne-atherosclerosis (ukuqina kwemithambo) kunokunciphisa umngcipheko.
