Antiagregación en pacientes con fractura subcapital desplazada de fémur tratados con prótesis parcial cementada. Estudio de complicaciones y mortalidad

Abstract

ObjectiveTo assess complications and factors predicting one-year mortality in patients on antiplatelet agents presenting with femoral neck fractures undergoing hip hemiarthroplasty surgery. Material and methodsA review was made on 50 patients on preoperative antiplatelet agents and 83 patients without preoperative antiplatelet agents. Patients in both groups were treated with cemented hip hemiarthroplasty. A statistical comparison was performed using epidemiological data, comorbidities, mental state, complications and mortality. There was no lost to follow-up. ResultsThe one-year mortality was 20.3%. In patients without preoperative antiplatelet agents it was 14.4% and in patients with preoperative antiplatelet agents was 30%. Age, ASA grade, number of comorbidities and antiplatelet agent therapy were predictors of one-year mortality.The one-year mortality of patients on clopidogrel was 46.1%, versus 24.3% in patients on acetylsalicylic acid. ConclusionPatients with preoperative antiplatelet therapy were older and had greater number of comorbidities, ASA grade, delayed surgery, and a longer length of stay than patients without antiplatelet therapy. The one-year mortality was higher in patients with preoperative antiplatelet therapy.
