Inani eliphelele lokubuya kwe-pulmonary venous

Ingqikithi ye-pulmonary venous return (TAPVR) iyisifo senhliziyo lapho imithambo emi-4 ethatha igazi lisuka emaphashini iye enhliziyweni inganamatheli ngokujwayelekile kwi-atrium yesobunxele (ikamelo eliphezulu elingakwesokunxele senhliziyo). Esikhundleni salokho, banamathisela komunye umthambo wegazi noma ingxenye engalungile yenhliziyo. Sikhona ngesikhathi sokuzalwa (isifo senhliziyo esizalwe naso).

Imbangela yokubuya okuphelele kwe-venous pulmonary venous ayaziwa.

Ekujikelezeni okujwayelekile, igazi lithunyelwa lisuka ku-ventricle elifanele ukuyothatha umoya-mpilo emaphashini. Libe selibuyela emithanjeni yamaphaphu (yamaphaphu) ohlangothini lwesobunxele lwenhliziyo, oluthumela igazi nge-aorta nangokuzungeza umzimba.

Ku-TAPVR, igazi elicebile oksijini libuya emaphashini liye e-atrium yangakwesokudla noma emthanjeni ogeleza ungene ku-atrium elungile, esikhundleni sohlangothi lwangakwesokunxele senhliziyo. Ngamanye amagama, igazi limane lizungeze liye noma lisuke emaphashini futhi lingaze liphume liye emzimbeni.

Ukuze usana luphile, i-atrial septal defect (ASD) noma i-patent foramen ovale (ukudlula phakathi kwe-atria yangakwesobunxele nangakwesokudla) kufanele kube khona ukuvumela igazi elinomoya-mpilo ukuba ligobele ohlangothini lwesobunxele lwenhliziyo nomzimba wonke.

Ukuthi lesi simo sinzima kangakanani kuncike ekutheni ingabe imithambo yamaphaphu ivinjiwe noma ayivinjelwe njengoba idonsa. I-TAPVR evinjelwe ibangela izimpawu zisencane futhi ingabulala ngokushesha okukhulu uma ingatholakali futhi ilungiswe ngokuhlinzwa.

Usana lungahle lubonakale lugula kakhulu futhi lungaba nalezi zimpawu ezilandelayo:

• Umbala we-Bluish wesikhumba (i-cyanosis)
• Izifo zokuphefumula njalo
• Imikhuba emibi
• Ukudla okungafanele
• Ukukhula okubi
• Ukuphefumula ngokushesha

Qaphela: Kwesinye isikhathi, akukho zimpawu ezingaba khona zisencane noma zisencane.

Ukuhlolwa kungafaka:

• I-catheterization yenhliziyo ingaqinisekisa ukuxilongwa ngokukhombisa ukuthi imithambo yegazi inamathiselwe ngokungavamile
• I-ECG ikhombisa ukukhuliswa kwama-ventricles (i-ventricular hypertrophy)
• I-Echocardiogram ingakhombisa ukuthi kunamathiselwe imikhumbi yamaphaphu
• I-MRI noma i-CT scan yenhliziyo ingakhombisa ukuxhumana phakathi kwemikhumbi yamaphaphu
• I-X-ray yesifuba ikhombisa okujwayelekile kuye enhliziyweni encane enoketshezi emaphashini

Ukuhlinzwa ukulungisa inkinga kuyadingeka ngokushesha okukhulu. Ekuhlinzeni, imithambo ye-pulmonary ixhunywe ku-atrium yesobunxele futhi ukukhubazeka phakathi kwe-atrium yangakwesokudla nangakwesobunxele kuvaliwe.

Uma lesi simo singelashwa, inhliziyo izokhula, iholele ekuhlulekeni kwenhliziyo. Ukulungisa iphutha kusenesikhathi kunikeza imiphumela emihle kakhulu uma kungekho ukuvinjelwa kwemithambo yamaphaphu ekuxhumekeni okusha okuya enhliziyweni. Izinsana ezivimbele imithambo ziye zaba nzima ukusinda.

Izinkinga zingafaka:

• Ubunzima bokuphefumula
• Ukwehluleka kwenhliziyo
• Isigqi senhliziyo esingajwayelekile, esisheshayo (arrhythmias)
• Ukutheleleka kwamaphaphu
• Umfutho wegazi ophezulu wamaphaphu

Lesi simo singabonakala ngesikhathi sokuzalwa. Kodwa-ke, izimpawu kungenzeka zingabi khona kuze kube kamuva.

Shayela umhlinzeki wakho wezokunakekelwa kwezempilo uma ubona izimpawu ze-TAPVR. Ukunakwa ngokushesha kuyadingeka.

Ayikho indlela eyaziwayo yokuvimbela i-TAPVR.
