Pulmonary arteriovenous fistula

Pulmonary arteriovenous fistula inobatana zvisina kujairika pakati petsinga uye mutsinga mumapapu. Nekuda kweizvozvo, ropa rinopfuura nemumapapu risina kuwana oxygen yakakwana.

Pulmonary arteriovenous fistula inowanzo kuve mhedzisiro yekusajeka kukura kwemitsipa yeropa yemapapu. Zvizhinji zvinoitika muvanhu vane nhaka yehemorrhagic telangiectasia (HHT). Vanhu ava vanowanzo kuve nemidziyo yeropa isina kujairika mune zvimwe zvikamu zvemuviri.

Fistula zvakare inogona kuve chinetso chechiropa chirwere kana kukuvara kwemapapu, kunyange izvi zvikonzero zviri zvishoma zvakanyanya.

Vanhu vazhinji havana zviratidzo. Kana zviratidzo zvikaitika, zvinogona kusanganisira:

• Sputum yeropa
• Kunetseka kufema
• Dambudziko rekudzidzira
• Mhino dzemhino
• Kufema kwekufema nekuedza
• Kurwadziwa pachifuva
• Ganda rebhuruu (cyanosis)
• Kubvarura kweminwe

Anokuchengetedza hutano achakuongorora. Bvunzo dzinogona kuratidza:

• Midzi yeropa isina kujairika (telangiectasias) paganda kana mucous membranes
• Ruzha rusina kujairika, rwunonzi kugunun'una kana stethoscope yakaiswa pamusoro peiyo isina kujairika yeropa
• Oxygen yakaderera kana ichiyerwa nepulse oximeter

Miedzo inogona kuitwa inosanganisira:

• Arterial yeropa gasi, iine uye isina oxygen (kazhinji kurapwa kweoksijeni hakugadzirise arterial reropa reropa zvakanyanya sekutarisirwa)
• Yakazara kuverenga ropa (CBC)
• Chest x-ray
• Chest CT scan
• Echocardiogram ine bubble kudzidza kutarisa mashandiro emoyo uye kuongorora kuvapo kweshunt
• Lung basa bvunzo
• Perfusion radionuclide lung scan kuyera kufema uye kutenderera (perfusion) munzvimbo dzese dzemapapu
• Pulmonary arteriogram kuona mapapu etsinga

Nhamba shoma yevanhu vasina zviratidzo vangangoda kurapwa. Kune vanhu vazhinji vane fistula, kurapwa kwesarudzo kuvhara fistula panguva ye arteriogram (embolization).

Vamwe vanhu vangangoda kuvhiyiwa kuti vabvise zvisizvo zvisina kujairika uye mapundu emapapu ari padyo.

Kana arteriovenous fistula ichikonzerwa nechiropa chirwere, kurapwa iko kuchinjirwa kwechiropa.

Maonero evanhu vane HHT haana kunaka kune avo vasina HHT. Kune vanhu vasina HHT, kuvhiyiwa kubvisa zvisizvo zvisina kujairika zvinowanzova nemhedzisiro yakanaka, uye mamiriro acho haazodzoke.

Kune vanhu vane chirwere chechiropa sechikonzero, kufungidzira kunoenderana nechiropa chirwere.

Zvinetso zvinogona kusanganisira:

• Kubuda ropa mupapu
• Kurohwa nekuda kweropa rinovhara iro rinofamba kubva mumapapu kuenda kumaoko, makumbo, kana huropi
• Utachiona muuropi kana mwoyo vharuvhu, kunyanya kune varwere vane HHT

Fonera mupiki wako kana iwe uchiwanzo kuve nemhino dzemhino kana kunetseka kufema, kunyanya kana iwe zvakare uine wega kana wemhuri nhoroondo yeHHT

Nekuti HHT inowanzo kuve majini, kudzivirira hakuwanzo kuitika. Genetic counselling inogona kubatsira mune dzimwe nguva.
