Niveles de calcificaciones vasculares en radiología convencional en pacientes hemodialisis en el Hospital General Isidro Ayora.

Title: Levels of vascular calcification in conventional radiology in hemodialysis patients in the "Isidro Ayora" General Hospital of the city of Loja. General Objetive: Determine the presence of vascular calcifications identified through conducting simple radiographs of hands , pelvis and lumbar region (Kauppila and Adragao test) , and the level of calcification and its possible correlation with altered mineral metabolism and cardiovascular comorbidity. Methods: A total of 59 hemodialysis patients over a period of 10 months (March-December 2013). Vascular calcifications were evaluated by X -ray of hands, pelvis and lumbar spine, and classified according to their severity and level of vascular calcification as Adragao index and Kaupilla. Clinical and radiological data were collected during the total study time. Results: Out of 59 patients, 33 cases (56 %) were male and 26 cases ( 44 % ) female, with a similar frequency of occurrence aged 51-60 years ( 22.03% ) and 71 to 80 ( 22.03% ) . hemodialysis in the period of between 12 to 24 months with 19 cases (32.20 %). Among the main causes that led patients to opt for replacement therapy in renal function, diabetes mellitus found 35 cases ( 59.32 %) and hypertension in 16 cases ( 27.12 %). The levels of vascular calcification were assessed through two radiological indices as well : Adragao test results shown as 23 cases ( 38.98% ) did not present any type of calcification and 14 cases ( 23.73% ) have the greater degree of vascular calcification ( 8 points), 29 cases (49.15 %) with severe vascular calcification was observed ≥ 3 according to this index, in age between 71 to 80 years with 9 cases ( 69.23 %) , in females with 15 cases ( 57.69 %) and having as basis the etiology of diabetes mellitus in 27 cases ( 77.14 %). Kauppila index shows 24 cases ( 40.68 %) without any calcification and 2 cases (3.39 %) with the highest degree of calcification (24 points ) . 19 cases (32.20 %) with severe vascular calcification , as Kaupilla index ≥ 6, aged 71 to 80 years with 6 cases ( 69.23 %) was observed in males with 11 cases ( 33.33 %) and whose underlying aetiology diabetes mellitus. The lumbar segment shown Vascular calcification is L4 , a level of the anterior wall of the aorta , with 14 cases ( 23.72% ) and at the rear wall of 11 cases ( 18.64% ) . Conclusions: Severe vascular calcifications identified through index Adragao and Kauppila, showed higher frequency of occurrence in patients with diabetes mellitus with 77.14% and 40% respectively, and L4, the most affected by vascular calcification in the lumbar segment anterior wall of the aorta, with 23.72%. Keywords: Hemodialysis vascular calcification, cardiovascular risk.
