Previous issue date: 2017-03-07 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A Doen?a Renal Cr?nica (DRC) leva a uma perda progressiva e irrevers?vel da
fun??o renal, e o seu est?gio final e mais grave exige uma terapia de suporte por meio
de hemodi?lise. Pacientes com DRC apresentam um maior risco de desenvolver
complica??es cardiovasculares, como a aterosclerose. Essa condi??o se caracteriza pelo
ac?mulo de placas gordurosas na camada ?ntima dos vasos sangu?neos, que quando
calcificadas podem ser observadas em radiografias panor?micas. O objetivo desta
pesquisa foi avaliar a ocorr?ncia dessas calcifica??es na art?ria car?tida (CAC)
detect?veis em radiografia panor?mica digital de pacientes com DRC submetidos ?
hemodi?lise. Os dados cl?nicos foram obtidos dos prontu?rios do setor de Nefrologia do
Hospital Onofre Lopes da UFRN e as radiografias panor?micas foram coletadas do
banco de dados do Servi?o de Imagenologia do Departamento de Odontologia da
UFRN. As an?lises dos exames foram feitas por um ?nico radiologista previamente
calibrado. Dos 309 pacientes integrantes da pesquisa, 15,9% apresentaram as
calcifica??es. Para verificar as associa??es entre a presen?a de CAC, e as vari?veis
independentes do estudo, os testes do Qui-quadrado e o exato de Fisher foram
utilizados. Foi verificada associa??o estatisticamente significativa (p?0,05) entre a
presen?a dessas calcifica??es com idade, sexo, tempo de hemodi?lise, diabetes mellitus
e alongamento do processo estil?ide. Os resultados revelaram uma alta ocorr?ncia de
CAC nos pacientes com DRC em hemodi?lise, quando comparados ? popula??o em
geral. / Chronic Kidney Disease (CKD) leads to a progressive and irreversible kidney
failure. The final and most severe stage of the disease often requires support therapy by
hemodialysis. CKD patients have a higher risk of developing cardiovascular
complications, such as atherosclerosis. This condition is characterized for the fatty
plaques accumulation in inner layer of blood vessels, which when calcified can be
observed on panoramic radiographs. The aim of this study was to evaluate the detectable
carotid artery calcifications (CAC) occurrence in digital panoramic radiography in CKD
patients undergoing hemodialysis. The clinical data were obtained from Nephrology
department records of the Onofre Lopes Hospital of Federal University of Rio Grande do
Norte, RN (UFRN) and the panoramic radiographs were collected from imaging service
database at the Dentistry Department of UFRN. The exams analyzes were done by a
single radiologist, previously calibrated. Of the 309 patients in the study, 15.9% had
calcifications. To verify the associations between the presence of CAC, and the
independent variables of the study, Chi-square and Fisher's exact tests were used. A
statistically significant association (p?0.05) was observed between the presence of these
calcifications and age, sex, hemodialysis time, diabetes mellitus and presence of styloid
process elongation. The results revealed a high occurrence of CAC in patients with CKD
on hemodialysis when compared to the general population.
