Aneurysms oziziritsa

Aneurysm ziwiya oziziritsa ndi boma pathological yodziwika ndi structural wakuswa ziwiya kupanga pa makoma awo monga mbali ya ntchito yophunzitsa thumba. Kawirikawiri, chifukwa cha matenda ndi kobadwa nako matenda kapena structural chosayenerera. Kawirikawiri anati pakuwonekera kwake chifukwa zoopsa kapena atherosclerosis.

Pa kuphwanya chomwecho akhoza ili mu madera osiyana a maukonde ubongo mtima. Komabe, monga ulamuliro, iwo zili pa maziko ake m'dera la bwalo la Willis.

Malinga mtundu wa chitukuko amadziŵika ndi arteriovenous magazi matenda.

Arteriovenous aneurysm cerebrovascular ankayimiridwa ngati koyilo ndi kukwaniritsidwa ziwiya venous. Mtundu wa kuphwanya amayamba ndi kukhazikitsidwa kwa kulankhulana pakati pa mwazi wa mtsempha, mtsempha wamagazi ndi limba. Amadziwika kuti magazi apamwamba kuposa venous. kulankhulana Direct pakati pa zotengera kumabweretsa ejection magazi mtsempha wamagazi mu mtsempha, anyalanyaza ubongo minofu. Pamene kumasulidwa imeneyi limodzi ndi kuthamanga. Izi zimapangitsa patsogolo khoma venous. Mitundu ya aneurysms ubongo. Zizindikiro mapangidwe yophunzitsa monga ululu kwambiri, matenda kuyenda ndi tilinazo khunyu. Chifukwa cha amayamba kuthamanga mkati kuwonjezeka ndi kupatulira makoma anapanga sacciform kutambasuka wang'ambidwa. Zimenezi, amachititsa intracranial magazi, nthawi zambiri itha imfa.

aneurysms wolumikizira ziwiya oziziritsa amapezeka mu mitsempha ndipo zikhoza kukhala osakwatira kapena angapo, ang'ono ndi lalikulu kwambiri. Malinga mtundu wa otaya limodzi ndi mawonetseredwe osiyana kuphwanya. matenda Asymptomatic tingaone mwangozi. aneurysms Unruptured akuwonetseredwa maganizo a psinjika za misempha cranial ndi ubongo, aakulu mutu. Komanso, matenda limodzi ndi kuphwanya fungo ndi masomphenya, khunyu, siudzalandilidwa ngathi lamulo la tilinazo khungu ndi nkhope.

Extension kusiyana kumabweretsa magazi mkati. Aneurysm chotupa limodzi ndi magazi, uyenera kubwerezedwa. Tikumbukenso kuti poyamba nkhani Tsoka amapezeka chakhumi kwa makumi atatu, ndi pa yopuma mobwerezabwereza - mlingo imfa Pafupifupi makumi asanu ndi awiri.

Pogwira miyeso matenda ndi zothandiza pamene pali nkhani ya magazi intracranial (Zomwe zinachitika wake). Nthawi zina pamaziko zizindikiro kukhazikitsa matenda enieni sizingatheke aneurysm. Mafotokozedwe matenda imagwiridwa ntchito angiography. Kafukufuku matenda ziwiya ubongo limasonyeza pamaso pa Ntchito yomangayi, kukula kwake ndi malo. Monga njira zina (zina) ntchito kompyuta (CT) ndi maginito kumveka (MR) kulingalira.

Oziziritsa aneurysms. Chithandizo.

Umboni wa matenda a yowonjezera maphunziro ndi umboni mwachindunji zochizira alowererepo pa opaleshoni. Nthawi zina, opaleshoni si anasonyeza mpaka pano pamene aneurysm kufika moyo pachiswe zamitundu mtima. opaleshoni akhoza kuchitika m'njira zosiyanasiyana. Nthawi zina zapadera, kopanira kutambasuka clamped ndi sakukhudzidwa potero ku chotengeracho lomwe anapanga. Izi kumatha chiopsezo chotupa ndi magazi. Mu mulandu wina, kuchotsa gawo bwanji ikuchitika ndi n'kubweretsa apulasitiki kapena kukhazikitsa chimango wapadera pakuti (stent).
