Aneurysm - ib tug tuag kab lus?

Aneurysm - ib tug extension ntawm cov hlab, ntau tshaj ob zaug nws ib txwm hauv lub cheeb. Tshaj 60% ntawm tag nrho cov aneurysm nyob rau hauv lub plab aorta. Qhov no pathology tshwm sim ntau rau cov neeg kev txom nyem los ntawm rheumatism, aortoarteritis, syphilis, atherosclerosis, tuberculosis. Ib tug ntau ua ntawm aneurysm - mob plab poob plig, phais ntawm lub aorta.

Lub mechanism ntawm tshwm sim

Lub rov tshwm sim ntawm tus expansion yog vim degenerative hloov nyob rau hauv aortic elastic ncej. Los ua tus kuj nyob rau hauv lub distal cov hlab ntsha tsub kom siab nyob rau hauv lub plab aorta. Yog hais tias muaj yog tsis muaj tau ntawm cov hlab los mus tiv overpressure tshwm sim nws extension nyob rau hauv ib tug qhov chaw. Aneurysm - aortic seem nrog turbulent ntshav tam sim no, uas yog feem ntau tsim nyob rau thrombi.

lub tsev kho mob

Nrog ib tug me me txoj kab uas hla ntawm lub aneurysm (tsawg tshaj li 20% ntawm cov neeg) yuav asymptomatic. Nyob rau hauv lwm yam mob, tag nrho cov kev soj ntsuam tej yam tshwm sim ntawm aneurysms raug muab faib ua raug thiab indirect. Raug: pulsatile mob plab, suab nrov thaum lub sij hawm lub contraction ntawm lub plawv ntawm lub aneurysm. Tus mob tej zaum yuav zoo li lub hepatic los yog lub raum Colic, laus nyob rau sab laug ntawm lub umbilicus, yuav radiate rau tom qab los yog duav.

indirect tej yam tshwm sim

• Abdominal syndrome: xeev siab, ntuav, tsis muaj qab los noj mov, poob phaus.
• Urological syndrome: hematuria dizuricheskie teeb meem.
• Ishioradikulyarny syndrome: mob, lub cev muaj zog thiab piav thoob hlo mob nyob rau hauv ob txhais ceg.
• Mob ischemia ob txhais ceg syndrome: quas ntus claudication, trophic hloov.

Aneurysm - yog lossi progressing kab mob. Ntau tshaj ib nrab ntawm cov neeg mob tuag tsis pub dhau 2 lub xyoo ntawm mob ntawm tej yam mob.

diagnostics

Ultrasound xeem tso cai rau koj mus muab cov qhov chaw nyob thiab qhov ntev ntawm kev kawm ntawv. Nyob rau saib lub aneurysm - ib tug sib npaug extension ntawm lub thawv nrog ntshiab nkhaus, pristenochnymi overlays thiab pab turbulent flow. Angiography qhia o ntawm lub aorta. X-ray duab nyob rau hauv lub txheej txheem cej luam nruab nrog cev ntawm lub plab kab noj hniav yuav pom ncua nkhaus ntawm lub aorta nrog lub deposition ntawm calcifications, feem ntau nrog los ntawm depressions nyob rau hauv lub pob txha caj qaum - Uzury. Thaum RT txhais ncig tag nrog ntshiab nkhaus, nyias cov phab ntsa, mural thrombus thiab calcifications.

kev kho mob

Aneurysm - ib tug kab mob nyob rau hauv uas feem coob ntawm cov neeg mob, kev phais yog ua, uas yog txuam nrog ib tug siab yuav qhov muaj tseeb ntawm cov teeb meem. Lag luam yog ua rau cov neeg mob uas tau raug kev txom nyem ib tug mob myocardial infarction, muaj ib tug keeb kwm ntawm lub plawv tsis ua hauj lwm, mob stroke.

hauj lwm kev pab

Muaj ntau ntau yam kev xaiv rau kev phais kho mob:

• tshem tawm ntawm ib tug aneurysm nrog lub aneurysmal lub hnab los sis prosthetic aortic bypass graft;
• tsis muaj tshem tawm ntawm lub aneurysm sac nrog vnutrimeshkovym prosthesis.

Khoom cuav yog feem ntau nrog aortofemoral cov khoom cuav. Lub neej no tom qab cov kev pab yog tsawg tshaj li 10%. Thaum kis tau rau phais ntawm aortic stenting yog ua: nqa los ntawm lub femoral leeg self-expanding prosthesis.

nyuab aneurysms

Lub txim ntawm aneurysm yog ncaj qha nyob rau nws luaj li cas: lub loj nws yog - qhov ntau dua nws bundles los yog kev sib tawg.
