Portocaval anastomosis like me ka pāʻoihana i ka pilikia a me kaʻike, o ka meaola

Mākou kino i ka loa noʻonoʻo kūpono-mai nenoaiu o ka holo. I Ina o ka pilikia i loko o kekahi o ka collateral holo ua ua hō'ā oihana, a ua kena ae la ma ke alo o anastomoses. Eia kekahi, i kēia mau collaterals kekahi manawa, hoakaka lapaʻau symptoms o kekahi mau maʻi.

Venous kanaka moku koko e māheleʻia i loko o ekolu nui hui: ka'ōnaehana o ka puka aa koko, haʻahaʻa a me nā keʻena ma puha aa koko. Kēlā me kēia no kēia mau pūʻulu hoʻolako i ke outflow o ke koko, mai kekahi mau mea o ke kino. Ma waena o ia mau mea, ma laila nō ka nui o ka hui i ka poe i kaheaia portocaval a me ka kava caval anastomoses. Nolaila, ina kekahi o na nenoai i ana, e like me blockage o na aa koko, a laila, ma muli o ia i ke alo o nā detours venous outflow ua ola.

Ano lawe i ka pili nana portocaval anastomoses. Ka mea, he poe i huiʻia o ka nū aa koko (V porta.) A malalo paha kekahi keena puha venous (V cava emi iki mahope o listen i oi.) A me na kēia wahi:

- ka lalo esophagus. Ke koko mai ka nū aa koko komo i ka opu aa koko, i mea kaiāulu anastomose i esophageal. Esophageal aa koko, ma ka huli, kahe i loko o ka unpaired a me ka hemiazygos aa koko e kahe ana i ka v. cava i oi;

- rectum. Ke outflow o ke koko ua lawe mai i loko o ekolu kumu mai o ka luna, waena a me nā wahi haʻahaʻa o ka mea. I ke koko kahe aku mai o ka luna i ka malalo mesenteric aa koko, waena - i ka na iliac, a mahope mai ka lalo - i loko o ka maloko anal (i hoakaka ia ma ka maloko iliac). Maoli ai, i loko o ka mānoanoa o ka rectum ka mea, e pili ana, a hana i portocaval anastomoses;

- anterior abdominal paia (puni ka umbilical apo). Complex anastomosis, na kumu o i mea na aa koko o nā mea a pau ekolu nenoai. Portal aa koko e umbilical aa koko a i hoonohonoho ia ma ka hoʻopoepoe laulau akepaʻa. Mai ka oi vena cava i loko o ke keena anastomosis komo pū epigastrium, akā, no ka mea, o ka mea emi vena - haʻahaʻa epigastrium Vienna;

- hakuʻala mea hōʻikeʻikeʻuʻuku. Ma kēia māhele 'āina, i ka hui ana o ka emi mesenteric aa koko (mai ka nū aa koko) a me kaʻaʻa puʻuwai aa koko (mai ka lalo o ka puha).

Au pono aku nei au i ka mea e ole wale portocaval anastomoses. Ma kekahi wahi hui i ka luna, a malalo vena cava. Ia mau hui i kapaia kava caval anastomoses. ʻEkolu o ia:

- anterior abdominal pā pōhaku. Ma waho anastomosis me ka puka aa koko, i ka lalo, a me ka luna hena kaiāulu, a ua pili i kekahi i kekahi;

- vertebral plexus. I ka luna spine aa koko anastomoses me ka wahi o ka aa koko'ōnaehana, ke poo a me ka'ā'ī puha luna, a ma ka haʻahaʻa - me lumbar aa koko o ka emi vena cava. Pela, ke anastomosis ua hanaʻia e ka vertebral plexus;

- malo. Lumbar cava (emi iki mahope o vena cava) a me ka unpaired a me ka hemiazygos cava (oi vena).

Meaning detours C. Brewer outflow. No ka laʻana, i loko o ka maʻi pale o ka puka hypertension mea he nui PalekanaEND_LINK kūlana portocaval anastomoses. Ka mea o ia i loko o ke alo o keia mai, he nui no ka lapaʻau hoikeana e pili ana me ia. Aia ua kahe ana ke koko mai ka esophageal varices, e like me ia mai ka rectum. Ke Classic symptom o ka "jellyfish poʻo". Ua hoike mai ai ia ia ma ka anterior abdominal paia, a ua kikooia aku anastomosing aa koko. A pau keia mea aie a hiki i ka nui, e hoike ana no ka mea, o ka mea mahuahua puʻe i loko o ka nū aa koko koko e kahe ana ma nā mea a pau i loaʻa ala ia ia. Nā kumu no ka puka hypertension mea ake maʻi, e like me cirrhosis, hepatitis, a me nā neoplastic lesions.

Penei, i ke alo o nā anastomoses mea he mea nui wahi i loko o ka functioning o ke kino. paani ka mea, i kekahiʻano nui kūlana ma na mea he nui mai keʻano o ka hanaʻana, a ua loa nui no ka kuokoa olelo hooholo ma ke kino o na pilikia, a no kaʻike, o kekahi mau pathologies.
