Uxinzelelo lwegazi

Uxinzelelo lwegazi oluhlaziyiweyo luxinzelelo lwegazi oluphezulu ngenxa yokuncipha kwemithambo ehambisa igazi kwizintso. Le meko ibizwa ngokuba yi-renal artery stenosis.

I-renal artery stenosis kukunciphisa okanye ukuvaleka kwemithambo ebonelela ngegazi kwizintso.

Unobangela oqhelekileyo we-renal artery stenosis kukuvaleka kwemithambo ngenxa ye-cholesterol ephezulu. Le ngxaki yenzeka xa into encangathi, enamafutha ebizwa ngokuba yiplaque yakha ngaphakathi kwimithambo, ibangela imeko eyaziwa ngokuba yi-atherosclerosis.

Xa imithambo ehambisa igazi kwizintso zakho iba mxinwa, kuncinci igazi elihamba liye kwizintso. Izintso ziphendula ngempazamo ngokungathi uxinzelelo lwegazi lusezantsi. Ngenxa yoko, zikhupha iihormoni ezixelela umzimba ukuba ubambelele kwityuwa eninzi kunye namanzi. Oku kubangela ukuba uxinzelelo lwegazi lwakho lukhuphuke.

Imiba yomngcipheko we-atherosclerosis:

• Igazi elonyukayo
• Ukutshaya
• Seswekile
• Cholesterol ephezulu
• Ukusetyenziswa kotywala kakhulu
• Ukusetyenziswa gwenxa kwecocaine
• Ukwanda kweminyaka

I-Fibromuscular dysplasia sesinye sezizathu zomchiza we-renal stenosis. Ihlala ibonwa kwabasetyhini abangaphantsi kweminyaka engama-50. Ihlala ibaleka kwiintsapho. Imeko ibangelwa kukukhula ngokungaqhelekanga kweeseli kwiindonga zemithambo ekhokelela kwizintso. Oku kukhokelela ekunciphiseni okanye ekuvaleni kwale mithambo.

Abantu abanesifo soxinzelelo lwegazi abanokuba nembali yoxinzelelo lwegazi oluphezulu kakhulu ekunzima ukuhla nalo kunye namayeza.

Iimpawu zoxinzelelo lwexinzelelo lwegazi zibandakanya:

• Uxinzelelo lwegazi xa usemncinci
• Uxinzelelo lwegazi oluphakama ngesiquphe okanye kunzima ukulilawula
• Izintso ezingasebenzi kakuhle (oku kungaqala ngequbuliso)
• Ukuxinana kweminye imithambo emzimbeni, efana nasemilenzeni, kwingqondo, emehlweni nakwezinye iindawo
• Ukwakhiwa ngesiquphe kolwelo ngeengxowa zomoya zemiphunga (i-pulmonary edema)

Ukuba unesimo esiyingozi soxinzelelo lwegazi olubizwa ngokuba yingozi yoxinzelelo lwegazi, iimpawu zingabandakanya:

• Intloko ebuhlungu
• Isihlunu okanye ukugabha
• Ukudideka
• Utshintsho kumbono
• Iimpumlo

Umboneleli wezempilo unokuva ingxolo ethi "whooshing", ebizwa ngokuba yibruit, xa ubeka istethoscope ngaphezulu kwesisu sakho.

Olu vavanyo lwegazi lulandelayo lunokwenziwa:

• Amanqanaba echolesterol
• Amanqanaba eRenin kunye nealdosterone
• BUN - uvavanyo lwegazi
• I-Creatinine-uvavanyo lwegazi
• Uvavanyo lwegazi lwePotassium
• Ukucoca creatinine

Ukulinganisa iimvavanyo kunokwenziwa ukubona ukuba imithambo yegazi yezintso inciphile na. Ziquka:

• I-Angiotensin eguqula i-enzyme (ACE) inhibition renography
• I-Doppler ultrasound yemithambo yegazi
• Imagnetic resonance angiography (MRA)
• Umthambo we-renal angiography

Uxinzelelo lwegazi olubangelwa kukuncipha kwemithambo ekhokelela kwizintso kuhlala kunzima ukuyilawula.

Elinye okanye ngaphezulu amayeza ayafuneka ukunceda ukulawula uxinzelelo lwegazi. Zininzi iintlobo ezikhoyo.

• Wonke umntu uphendula amayeza ngokwahlukileyo. Uxinzelelo lwegazi kufuneka luhlolwe rhoqo. Inani kunye nohlobo lwamayeza owathathayo anokufuna ukutshintsha amaxesha ngamaxesha.
• Buza umboneleli wakho ukuba ufunda ntoni uxinzelelo lwegazi.
• Thatha onke amayeza ngendlela obonelelwe ngayo ngumboneleli wakho.

Ngaba amanqanaba akho e-cholesterol akhangelwe, kwaye anyangwe xa kufuneka njalo. Umboneleli wakho uya kunceda ukumisela amanqanaba e-cholesterol afanelekileyo kuwe ngokubhekisele kumngcipheko wesifo sentliziyo kunye nezinye iimeko zempilo.

Utshintsho kwindlela yokuphila lubalulekile:

• Yitya ukutya okusempilweni ngentliziyo.
• Zilolonge rhoqo, ubuncinci imizuzu engama-30 ngosuku (jonga ugqirha ngaphambi kokuba uqale).
• Ukuba uyatshaya, yeka. Fumana inkqubo eya kukunceda uyeke.
• Nciphisa utywala obuselayo: 1 isiselo ngemini kubafazi, 2 ngosuku kumadoda.
• Nciphisa inani lesodium (ityuwa) oyityayo. Cwangcisa ngaphantsi kwe-1,500 mg ngosuku. Jonga ugqirha wakho malunga nokuba ungayidla kangakanani i-potassium.
• Ukunciphisa uxinzelelo. Zama ukunqanda izinto ezibangela uxinzelelo kuwe. Unokuzama ukucamngca okanye iyoga.
• Hlala kubunzima bomzimba osempilweni. Fumana inkqubo yokunciphisa umzimba ukukunceda, ukuba uyayifuna.

Olunye unyango luxhomekeke kwinto ebangela ukuhla kwemithambo yegazi. Umboneleli wakho unokucebisa ngenkqubo ebizwa ngokuba yi-angioplasty nge-stenting.

Ezi nkqubo zinokukhetha ukuba une:

• Ukuncipha okumandla komthambo wezintso
• Uxinzelelo lwegazi olungenakulawulwa ngamayeza
• Izintso ezingasebenzi kakuhle kwaye ziya zisiba mbi

Nangona kunjalo, isigqibo sokuba ngabaphi abantu ekufuneka benazo ezi nkqubo sinzima, kwaye sixhomekeke kwizinto ezininzi ezidweliswe apha ngasentla.

Ukuba uxinzelelo lwegazi alulawulwa kakuhle, usengozini yezi ngxaki zilandelayo:

• Aortic aneurysm
• Ukuhlaselwa yintliziyo
• Ukumelwa yintliziyo
• Isifo sezintso esinganyangekiyo
• Ukubetha
• Iingxaki zombono
• Ukunikezelwa kwegazi okungalunganga kwimilenze

Biza umnikezeli wakho ukuba ucinga ukuba unoxinzelelo lwegazi oluphezulu.

Fowunela umnikezeli wakho ukuba unexinzelelo lwegazi kunye neempawu ziba mandundu okanye zingaphuculi unyango. Biza kwakhona ukuba iimpawu ezintsha ziyavela.

Ukuthintela i-atherosclerosis kunokuthintela i-renal artery stenosis. Ukuthatha la manyathelo alandelayo kunokunceda:

• Ukunciphisa umzimba ukuba utyebe kakhulu.
• Buza umboneleli wakho malunga nokutshaya kunye nokusetyenziswa kotywala.
• Lawula iswekile yegazi lakho ukuba unesifo seswekile.
• Qinisekisa ukuba umboneleli wakho ujonge amanqanaba e-cholesterol yakho.
• Yitya ukutya okusempilweni ngentliziyo.
• Yenza umthambo rhoqo.
