¿Existe algún factor de riesgo predictivo de mortalidad a corto plazo en pacientes de alto riesgo intervenidos de aneurismas de aorta abdominal mediante endoprótesis? / Is there any predictive risk factor of short-term mortality in high risk patients operated on for aortic abdominal aneurysms using endoprosthesis?

OBJETIVOS: Identificar factores predictivos de mortalidad a corto plazo (<24 meses) en pacientes con aneurisma de aorta abdominal (AAA), de alto riesgo quirúrgico, tratados mediante endoprótesis. MATERIAL Y MÉTODOS: Estudio retrospectivo mediante revisión de historias clínicas entre enero de 2006 y junio de 2010. El seguimiento medio de los pacientes fue de 23,7 meses (DE = 16,3; rango: 0-62). Se compara el grupo de mortalidad a corto plazo (<24 meses) con el resto, mediante regresión logística multivariante. RESULTADOS: El 3,5% (2 casos) falleció durante el ingreso y el 30,9% (17 casos) durante el periodo de seguimiento. La media de supervivencia fue 41,1 meses (34-48,2; mediana = 40 meses). La mortalidad antes de 24 meses fue el 21% (12 pacientes). En el análisis multivariante se encontró que el único factor predictivo de mortalidad a corto plazo fue la presencia de enfermedad pulmonar obstructiva crónica (EPOC) (p = 0,014; OR 13,7; IC = 1,7-109). CONCLUSIONES: La EPOC en pacientes de alto riesgo quirúrgico parece ser indicativa de mortalidad a corto plazo

OBJECTIVES: To detect any risk factor of short-term mortality in high risk patients undergoing endovascular abdominal aortic aneurism (EVAR) repair. MATERIAL AND METHODS: A retrospective study was conducted from January 2006 to June 2010, with a mean follow-up of 23.7 months. A multiple logistic regression model was used to evaluate variables of mortality after EVAR in early mortality patients. RESULTS: Two (3.5%) cases died during hospital admission, and 30.9% during the follow-up period. Short-term mortality rate (before 24 months) was 21% (12 patients). chronic obstructive pulmonary disease (COPD) was the only significant predictor of short-term mortality (P=.014; OR 13.7; 95% CI = 1.7-109). CONCLUSIONS: COPD in high risk patients could predict short-term mortality after EVAR

Cystic adventitial disease of the popliteal artery: Two case reports and a review of the literature.

Two cases of cystic adventitial disease treated at our institution over the last year are presented. They were middle-aged and apparently healthy patients, and the symptoms begin with a sudden onset of unilateral claudication. After performing a magnetic resonance angiography, a cystic formation attached to the adventitia of the popliteal artery was identified. Both patients were treated in the same manner, with resection of the affected arterial segment and vein bypass interposition. Both remain asymptomatic after one year of follow-up in one case and six months in the other. Cystic adventitial disease is a rare entity, which presents in patients without cardiovascular risk factors, so sometimes it takes long to reach a definitive diagnosis. Concerning the different treatment options, cyst excision together with the affected arterial segment seems to offer better mid- and long-term results when compared with other treatment options such as cyst aspiration or endovascular techniques, although there are no multicenter trials evidencing the superiority of one against the others.
