Qhov Tseem Ceeb Qhov txawv - Aneurysm vs Hemorrhage
Txawm hais tias Aneurysm thiab Hemorrhage yog ob qho kev kho mob ntshav, muaj qhov sib txawv ntawm lawv. Qhov sib txawv tseem ceeb ntawm ob qho xwm txheej no yog qhov aneurysm yog ib qho kev txawv txav ntawm lub cev uas qhov chaw dilation tshwm sim hauv phab ntsa ntawm cov hlab ntsha thaum hemorrhage yog ib qho mob pathological uas cov ntshav khiav tawm ntawm cov hlab ntsha. Txawm li cas los xij, rupture ntawm aneurysm tuaj yeem xaus nrog cov hemorrhage loj.
Dab tsi yog aneurysm?
Aneurysm yog ib qho chaw dilatation hauv phab ntsa ntawm cov hlab ntsha. Nws yuav zoo li lub zais pa uas muaj ntshav nrog rau cov hlab ntsha. Aneurysms tuaj yeem tshwm sim hauv txhua cov hlab ntsha ntawm lub cev. Qee qhov piv txwv rau aneurisms yog aneurysms ntawm lub voj voog ntawm Willis, uas nyob rau hauv lub hauv paus ntawm lub hlwb, thiab aortic aneurysms cuam tshuam rau lub thoracic los yog plab aorta. Qee zaum, aneurysms tuaj yeem tshwm sim hauv ventricles ntawm lub plawv nws tus kheej. Qhov no feem ntau tshwm sim vim qhov tsis muaj zog ntawm phab ntsa ventricular los ntawm ischemic puas.
Aneurisms zoo li loj tuaj nrog lub sijhawm. Qhov no tej zaum yuav nrog los ntawm qhov tsis muaj zog los yog thinning tawm ntawm nws phab ntsa. Yog li ntawd, aneurysms muaj kev pheej hmoo ntawm rupture. Ib qho ruptured aneurysm tuaj yeem ua rau tuag taus hemorrhage ua rau hypovolemic shock thiab tuag. Aneurysms tshwm sim vim kev tsis muaj zog ntawm cov hlab ntsha ntawm phab ntsa lossis qhov tsis muaj zog ntawm phab ntsa ntawm cov hlab ntsha los ntawm ntau yam xws li degeneration, atherosclerosis, thiab kab mob. Aneurysms kuj tuaj yeem yog qhov chaw rau kev tsim cov ntshav txhaws (thrombosis) thiab embolization (tso tawm ntawm cov hlab ntsha ua rau muaj kev cuam tshuam ntawm cov ntshav ntws hauv cov kab mob hauv nruab nrog cev. Muaj ob hom mob aneurysms.
- Ib qhov tseeb qhov tseeb: Phab ntsa ntawm qhov aneurysm yog tsim los ntawm phab ntsa hlab ntsha nws tus kheej.
- Ib qho tsis tseeb aneurysm (pseudoaneurysm): yog ib yam mob uas cov ntshav tawm ntawm cov hlab ntsha thiab phab ntsa tawm ntawm cov hlab ntsha los ntawm cov ntaub so ntswg ib puag ncig.
Radiological cov txheej txheem xws li ultrasonic scanning, sib piv-txhim kho CT scanning, thiab lwm yam. yog siv los kuaj mob aneurysms. Kev xaiv loj hlob aneurysms yog kho los ntawm kev phais. Tam sim no, muaj ntau yam kev cuam tshuam xov tooj cua uas lub catheter tau dhau los ntawm cov hlab ntsha mus txog qhov chaw ntawm qhov aneurism thiab ntau cov txheej txheem (clipping, coiling) yog siv los cuam tshuam cov kab noj hniav ntawm qhov aneurism. Cov technics no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau qhov chaw phais tsis tau xws li lub hauv paus ntawm lub hlwb.
Hemorrhage yog dab tsi?
Ntshav lossis hemorrhaging txhais tau tias yog ntshav khiav tawm ntawm lub cev. Qhov loj ntawm cov ntshav tuaj yeem nyob ntawm qhov me me capillary qib los ntshav mus rau lub neej loj heev los ntshav. Los ntshav tuaj yeem tshwm sim sab hauv hauv lub cev, qhov twg cov ntshav tawm los ntawm cov hlab ntsha hauv lub cev, lossis sab nraud, los ntawm kev qhib ntuj (xws li lub qhov ncauj, urethra) lossis los ntawm kev raug mob ntawm daim tawv nqaij. Tus neeg noj qab haus huv tuaj yeem tiv taus qhov poob ntawm 10-15% ntawm tag nrho cov ntshav ntim yam tsis muaj qhov tshwm sim loj. Kev tso tseg los ntshav yog hu ua hemostasis.
ntshav poob tau categorized li hauv qab no.
- Class I Hemorrhage: nce mus txog qhov poob ntawm 15% ntawm cov ntshav ntim. Yuav tsis muaj qhov hloov pauv ntawm cov cim tseem ceeb.
- Class II Hemorrhage: nce mus txog qhov poob ntawm 15-30% ntawm tag nrho cov ntshav ntim. Tus neeg mob yuav muaj lub plawv dhia ceev nrog lub plawv nqaim (qhov qis ntawm qhov sib txawv ntawm systolic thiab diastolic ntshav siab).
- Class III Hemorrhage: mus txog qhov poob ntawm 30-40% ntawm cov ntshav ntim. Tus neeg mob ntshav siab yuav poob thiab lub plawv dhia yuav nce
- Class IV Hemorrhage: mus txog qhov poob ntawm >40% ntawm cov ntshav ntim. Lub cev yuav tsis muaj peev xwm them rov qab rau cov ntshav poob thiab pom zoo kom resuscitation tam sim.

Qhov txawv ntawm Aneurysm thiab Hemorrhage yog dab tsi?
Definition of Aneurysm thiab Hemorrhage
Hemorrhage: Los ntshav lossis hemorrhaging txhais tau tias yog ntshav khiav tawm ntawm lub cev.
Aneurysm: Ib qho aneurysm tuaj yeem txhais tau tias yog ib qho chaw dilatation hauv phab ntsa ntawm cov hlab ntsha.
Yam ntxwv ntawm Aneurysm thiab Hemorrhage
Pathophysiological hauv paus
Aneurysm: Aneurysm yog qhov txawv txav ntawm lub cev.
Hemorrhage: Hemorrhage is a pathological mob.
Kev nce qib
Aneurysm: Aneurysm maj mam nce.
Hemorrhage: Hemorrhage yog nrawm nrawm.
Kev nyuaj siab
Aneurysm: Aneurysm feem ntau ua rau thromboembolism.
Hemorrhage: Hemorrhage ua rau hypovolemic shock.
Lub cev teb
Aneurysm: Lub cev tsis muaj qhov system los tiv thaiv kev tsim ntawm aneurysms.
Hemorrhage: Lub cev muaj txoj hauv kev los tswj cov ntshav los ntawm kev kaw qhov tsis xws luag hauv lub nkoj.
Kev kho mob
Aneurysm: Aneurysm tuaj yeem pom yam tsis tau kho yog tias me me.
Hemorrhage: Hemorrhage yuav luag txhua zaus tswj tau.
