a vaselor piale și evoluarea unui tablou clinic asimetric.<br />

Rezumat<br />

Prezentul studiu pe un lot <strong>de</strong> 51 <strong>de</strong> pacienţi a contribuit<br />

la evaluarea valorii procesului <strong>de</strong>generative-distrofic<br />

vertebral în patogeneza tulburărilor ischemice<br />

medulare <strong>de</strong> nivel toracic. Meto<strong>de</strong>le neuroimagistice au<br />

pus în evi<strong>de</strong>nţă hernii discale, osificarea ligamentului<br />

flav și longitudinal posterior, în asociere cu stenozarea<br />

congenitală a canalului medular <strong>de</strong> nivel toracic, fracturi<br />

tasate, osteofite posterioare, stenozarea laterală a<br />

canalului medular, cauzată <strong>de</strong> hipertrofia articulaţiilor<br />

intervertebrale, pe fundalul cărora s-au <strong>de</strong>zvoltat atât<br />

forme clinice cu evolutie simetrică prin compresia vaselor<br />

spinale magistrale, cât și asimetrică prin compresia<br />

medulară.<br />

Summary<br />

Th e study of 51 patients contributed to the assessment<br />

of the role of <strong>de</strong>generative-dystrophic modifi cations of the<br />

spinal column in the pathogenesis of thoracic ischemic<br />

medullar disturbances. Neuroimaging investigations highlighted<br />

the disc herniations, ossifi cation of fl avum and<br />

posterior longitudinal ligaments in association with congenital<br />

spinal canal stenosis of the thoracic level, vertebral<br />

compression fractures, posterior osteophytes, lateral spinal<br />

canal stenosis caused by hypertrophy of the facet joints, on<br />

which background both symmetrical and asymmetric clinical<br />

forms <strong>de</strong>veloped due to compression of spine or spinal<br />

vessels.<br />

Резюме<br />

Данное исследование группы из 51 пациентов<br />

позволило оценить роль дегенеративнодистрофического<br />

процесса позвоночника в патогенезе<br />

ишемических нарушений спинного мозга на грудном<br />

уровне. Нейровизуализационные методы выявили<br />

грыжи дисков, оссификацию задней продольной и<br />

жёлтой связок в комбинации с врождённым стенозом<br />

позвоночного канала на грудном уровне, компрессионные<br />

переломы, задние остеофиты, латеральный<br />

стеноз позвоночного канала вызванный гипертрофией<br />

дугоотростчатых суставов, на фоне которых были<br />

отмечаны клинические формы с симметричным и<br />

асимметричным течением, вызванным компрессией<br />

магистральных сосудов или непосредственным сдавлением<br />

спинного мозга.
