Kuvharidzirwa kweSVC

Kuvharirwa kweSVC kudzikisira kana kuvhara kweiyo yepamusoro vena cava (SVC), inova yechipiri tsinga huru mumuviri wemunhu. Iyo yepamusoro vena cava inofambisa ropa kubva kumusoro kwehafu yemuviri kuenda pamoyo.

Kuvharidzirwa kweSVC chiitiko chisingawanzoitika.

Iyo inowanzo kukonzerwa nekenza kana bundu mune iyo mediastinum (iyo nzvimbo yechipfuva pazasi pechifuva uye pakati pemapapu).

Dzimwe mhando dzekenza dzinogona kutungamira kune aya mamiriro dzinosanganisira:

• Gomarara repazamu
• Lymphoma
• Kenza yemapapu yemapapu (kenza yemapapu inopararira)
• Gomarara repachiedza
• Gomarara redundira
• Thymus bundu

Kuvhiringidzika kweSVC kunogona kukonzerwa nemamiriro asiri ecancer anokonzera kuora. Aya mamiriro anosanganisira:

• Histoplasmosis (rudzi rwehutachiona hutachiona)
• Kuzvimba kweiyo tsinga (thrombophlebitis)
• Zvirwere zvemapapu (senge tibhii)

Zvimwe zvikonzero zvekudzivirirwa kweSVC zvinosanganisira:

• Aortic aneurysm (kuwedzera kwetsinga inosiya moyo)
• Ropa rinovhara muSVC
• Zvinokanganisa pericarditis (kuomesa kwetambo yakatetepa yemoyo)
• Mhedzisiro ye radiation radiation kune mamwe marapirwo mamiriro
• Kuwedzera kwetachiona gland (goiter)

Catheters akaiswa mumitsinga mikuru yeruoko rwepamusoro nemutsipa zvinogona kukonzera kuwanda kweropa muSVC.

Zviratidzo zvinoitika kana chimwe chinhu chichivhara ropa kuyerera richidzokera kumoyo. Zviratidzo zvinogona kutanga kamwe kamwe kana zvishoma nezvishoma, uye zvinogona kuwedzera kana iwe uchikotama kana kurara pasi.

Zviratidzo zvekutanga zvinosanganisira:

• Kuzvimba kutenderedza ziso
• Kuzvimba kwechiso
• Kuzvimba kwevachena vemaziso

Iko kuzvimba kungangove kwakanyanya kuwanda mumangwanani emangwanani uye woenda pakati pemangwanani.

Zviratidzo zvakajairika kuperevedza mweya (dyspnea) uye kuzvimba kwechiso, mutsipa, trunk, nemaoko.

Zvimwe zvinogona kuitika zvinosanganisira:

• Kuderedza kusvinura
• Dzungu, kupera simba
• Kutemwa nemusoro
• Chiso chitsvuku kana matama
• Machindwe matsvuku
• Reddish mucous membranes (mukati memhino, muromo, uye dzimwe nzvimbo)
• Kutsvuka kuchichinja kuva kubhuruu gare gare
• Kunzwa kwekuzara kwemusoro kana nzeve
• Chiono chinoshanduka

Mubatsiri wezvehutano anoita bvunzo dzepanyama, dzinogona kuratidza kuwedzerwa mitsipa yechiso, mutsipa, uye nechepamusoro chifuva. Ropa kumanikidza rinowanzo kuve rakakwira mumaoko uye rakadzika mumakumbo.

Kana kenza yemapapu ichifungidzirwa, bronchoscopy inogona kuitwa. Munguva iyi maitiro, kamera inoshandiswa kuona mukati memhepo uye mapapu.

Kuvharika kweSVC kunogona kuoneka pa:

• Chest x-ray
• CT scan yechipfuva kana MRI yechipfuva
• Coronary angiography (moyo weropa mudziyo kudzidza)
• Doppler ultrasound (ruzha wave bvunzo yemidziyo yeropa)
• Radionuclide ventriculography (kudzidza kwenyukireya kwekufamba kwemoyo)

Chinangwa chekurapa ndechekusunungura iko kuvharika.

Diuretics (mapiritsi emvura) kana steroid (anti-anogumbura zvinodhaka) inogona kushandiswa kumbopedza kuzvimba.

Dzimwe nzira dzekurapa dzinogona kusanganisira radiation kana chemotherapy yekudzora bundu, kana kuvhiya kubvisa mamota. Kuvhiya kupfuudza iko kuvharira hakuwanzo kuitwa. Kuiswa kwe stent (chubhu yakaiswa mukati meropa reropa) kuvhura iyo SVC inogona kuitwa.

Mhedzisiro yacho inosiyana, zvinoenderana nechakakonzera uye huwandu hwekuvhara.

SVC kuvharirwa kunokonzerwa nebundu chiratidzo chekuti bundu rapararira, uye zvinoratidza murombo kwenguva refu maonero.

Huro inogona kuvharika, inogona kuvhara nzira dzekufema.

Kuwedzera kwekumanikidza kunogona kukura muuropi, zvichitungamira kune akachinja mazinga ekuziva, kuda kurutsa, kurutsa, kana kuchinja kwemaonero.

Fonera mupiki wako kana iwe ukaita zviratidzo zvekudzivirira kweSVC. Zvinetso zvakakomba uye dzimwe nguva zvinogona kuuraya.

Kukurumidza kurapwa kwehumwe kusagadzikana kwekurapa kunogona kudzora njodzi yekuvharirwa kweSVC.
