Iyo yepasi vena cava ndeimwe yeidzi huru tsinga mumuviri.

nzvimbo. Iyo yakaderera vena cava inonyanya kuwanikwa mudumbu.

mavambo. Iyo yakaderera vena cava inomuka padanho rechishanu lumbar vertebra. Iyo inowirirana nekubatana kweyakajairika iliac mitsetse. (5) (1)

Nzira. Iyo yakaderera vena cava inomhanya ichikwira kumberi kwemitumbi ye vertebral uye kumashure kweaorta kune yekutanga lumbar vertebra. Iyo inoenderera ichisimuka, ichinamira kurudyi, uye ichipfuura neiyo diaphragmatic orifice. (1) (2)

Kuguma. Iyo yepasi vena cava inobatana uye inopera padanho reatrium yekurudyi. (1) (2) Padanho iri, pakaumbwa mhasuru, inonzi vharuvhu yeiyo yakaderera vena cava kana vharuvhu yeEustachi.

Collateral matavi. Mazhinji matavi emakorari akavhurika munzira yeakaderera vena cava (1) (2):

• Lumbar tsinga. Ivo vanogadzira satellite tsinga mune lumbar arteri. Tsinga yega yega inoperera kuseri kwenzvimbo yepasi vena cava.
• Tsinga dzetsvo. Kugadzira matanda maviri ane huturu, tsinga dzetsvo dzinovhurika panzvimbo dzakapfurikidza dzeiyo yakaderera vena cava padanho rekutanga lumbar vertebra.
• Kurudyi spermatic kana ovarian vein. Inokwira ichitevedza yakaderera vena cava isati yapera pazasi pekuvhurika kweiyo renal veins.
• Kurudyi kwepakati adrenal kana capsular vein. Ino vhura pamusoro pechiso chekumashure kwenzvimbo yepasi yepasi, pakati pekuvhurwa kwemitsipa yetsvo uye nzira inopfuura neiyo diaphragmatic orifice.
• Hepatic tsinga. Kazhinji zviri zviviri, idzi tsinga dzinoguma munzvimbo yepasi vena cava pazasi pechirahwe.
• Tsinga dzemuzasi dzemitsipa. Ivo vanovhura pamberi pechiso chepamberi peiyo yakaderera vena cava, padanho reiyo diaphragmatic ndima.

Iyo yakaderera vena cava inotungamira ine venous ropa kune moyo, uye zvakanyanya kunyanya kurudyi atrium (1) (2).

Phlebitis. Iyo inonziwo venous thrombosis, chirwere ichi chinoenderana nekuumbwa kweropa, kana thrombus, mutsinga. Mavhinga aya anogona kufamba uye kukwira kune yakaderera vena cava. Ichi chirwere chinogona kutungamira kune akasiyana mamiriro senge venous insufficiency. Iyo yekupedzisira inoenderana nekusagadzikana kweiyo venous network. Kana izvi zvikaitika padanho repasi vena cava, iro ropa rinotyisa rinobva rakasanodonhedzwa uye rinogona kukanganisa kutenderera kweropa kwese (3).

Tumor. Benign kana yakaipa, mamota anogona kukura mune yakaderera vena cava. Zvisinei, kukura kwekenza uku hakuwanzoitika (4) (5).

Trauma. Kutevera kuvhunduka kwechisimba, iyo yakaderera vena cava inogona kupinda mukutambudzika. Izvi zvinogona kuratidzwa ne hypovolaemia, ndiko kuti, kushomeka kweropa. (4)

Kurapwa. Zvichienderana nehutachiona hwakawanikwa, mimwe mishonga inogona kupihwa seanticoagulants kana anti-aggregants.

Thrombolyse. Inoshandiswa panguva yemyocardial infarction, kurapwa uku kunosanganisira kupwanya iyo thrombi, kana kuwanda kweropa, nerubatsiro rwemishonga.

Kuvhiya kurapa. Zvichienderana nechirwere chakaonekwa, kuvhiyiwa kunogona kudikanwa.

Chemotherapy, radiotherapy, hormone therapy, yakanangwa kurapa. Zvichienderana nerudzi uye nhanho yebundu, aya marapirwo anogona kushandiswa kuparadza gomarara maseru. (5)

Kuongorora kwepanyama. Kutanga, kuongororwa kwekiriniki kunoitwa kuongorora zviratidzo zvinoonekwa nemurwere.

Chiremba imaging bvunzo. Kuti upedze kana kusimbisa kuongororwa, Doppler ultrasound, CT scan, kana MRI inogona kuitwa.

Ichinzi sevhavha yeEustachi, iyo yakaderera vena cava vharuvhu inonzi zita remukurumbira wezana ramakore rechi16 Italian anatomist uye chiremba, Bartolomeo Eustachi. (6)
