Zokugula semithambo. besisu useshonile yomthambo i-aorta

I-aorta ubizwa ngokuthi Umthambo eziyisisekelo elikhulu umzimba. It wenza umsebenzi ukuxhumana phakathi kwenhliziyo kanye izitho zangaphakathi.

Useshonile - normal ukukhulisa ukuthi avame ukuvela le-aorta. Zivela thinning, esigabeni buthaka bomkhumbi. High blood pressure kunomthelela ukunwetshwa. ukuxilongwa sekwephuzile we isifo kungaholela ukudabuka bomkhumbi ukopha ebulalayo. Ngaphezu kwalokho, ukunwebeka ikhuthaza ukuphazamiseka ukugeleza kwegazi, nakho kwandisa ingozi igazi ihlule kumiswa (thrombosis). A ihlule legazi zandise kanye unhlangothi semithambo, ngenkathi izakhi zalo wahlukana ungashukumisela ngemithambo yegazi. Ngakho, lapho embolism. Futhi phezu thinning odongeni semithambo akhiwa ngokweqile-calcium imali.

Izandiso zingase zimiswe kunoma iyiphi indawo semithambo. Besisu useshonile yomthambo i-aorta kuyagcinwa ezintathu kuzo ezine amacala aneurysms yomthambo i-aorta. Ifomu ukunwebeka okuholela kungenzeka isikhwama-okwenyanga noma fusiform.

Kutfutfukiswa useshonile besisu yomthambo i-aorta kungahle kubangelwe isifo sokuqina kwemithambo yegazi, umfutho ophakeme wegazi, izinqubo ukuvuvukala ezindongeni umkhumbi. Kumiswa izandiso lingaphathelaniswa ne azalwa naso zezinzwa izifo izicubu, futhi izifo ezithathelwanayo, ephelezelwa umonakalo odongeni yomthambo i-aorta.

Izimpawu besisu useshonile yomthambo i-aorta owabonakaliswa okungazelelwe nobuhlungu obukhulu ngemuva nasesiswini. Izenzo sifo ahambisana emizweni Ukwedlula izinhlangano esiswini. Ngesikhathi esifanayo isigqi sabo kuvumelana isigqi ukushaya kwenhliziyo. Akuvamile ngilugcinile ubuhlungu emilenzeni, ephelezelwa pallor yabo futhi "cyanosis", okuyinto kubangelwa yokufuduka thrombus izingcezu othelawayeka ekhipha igazi enhliziyweni.

Besisu yomthambo i-aorta useshonile ukudabuka ephelezelwa ukopha. ngaleyo ndlela Symptomatology incike isiqondiso igebe.

Intraperitoneal ukufohla besisu useshonile yomthambo i-aorta kwenzeka oluhambisana ukushaqeka, ephelezelwa nokuqinisa ukopha zangaphakathi. Ngaphezu kwalokho, kukhona blanching abukhali kwesikhumba, kwenhliziyo. eshaywayo besisu wembula khona uketshezi khulula e komgodi ongaphakathi kwamathumbu. Yiqiniso inhlekelele lesi sifo kulesi simo akubandakanyi noma yiphi ucwaningo. Ukufa kwenzeka ngokushesha ngokwanele.

igebe Retroperitoneal ephelezelwa ubuhlungu emuva aphansi noma esiswini.

Breakthrough ka besisu aneurysms yomthambo i-aorta e bakhiphe elezinga eliphansi vena cava libhekene iphika, ubuthakathaka, palpitations. Kulokhu kukhona izinhlungu esiswini ukwakha therein a ejabhile alandisa systolic-diastolic umsindo (buzz). Ngokwe-obubonakala ngendlela ehlelekile esingokwemvelo, kodwa inchubekelembili inexorable. Imiphumela iba yinhlanganisela yokukhandleka isifo senhliziyo ifomu ezinzima.

ukunwetshwa Igebe ohlangothini duodenum kuhambisana nciphisa okungazelelwe nihlanze wezimpi ezalandela.

Ukuhlola esigulini ngesimiso evundlile ngokuvamile baveza kwaqinisa okusizwa ukushaya useshonile. Palpation (iminwe kumba) ka engxenyeni engenhla esiswini (ngokuvamile ohlangothini kwesokunxele isikhungo line yayo) kuthola khona ejabhile isimila kumiswa. Njengomthetho, namanje kungenzeka maloboleznennym noma buhlungu. Auscultation (kulalela) itholwa hum systolic phezu imfundo. izandiso Small bungabonakala esebenzisa ikhompyutha tomography.

Njengomthetho, ukusetshenziswa jikelele zokwelashwa izindlela wezinsimbi kwenza kube nokwenzeka kahle ukuxilonga izifo ezigulini eziningi. Yingakho ukuqashwa kukaNksz aortography kuyadingeka kuphela ezimweni lapho imiphumela yocwaningo ungabonisi isithombe esicacile lesi sifo.

Banikezwe khona izinkinga ngokuzumayo, ukuphathwa besisu aneurysms yomthambo i-aorta is olwenziwe yi-op. Kule nqubo ukususwa kanye esikhundleni bomkhumbi abathintekayo.
