Vascular complications of infective endocarditis

Abstract

The complications of infective endocarditis (IE) are frequent and severe. Our objectives were to analyze the clinical, paraclinical, and prognostic features of IE vascular complications observed in two cardiology units, in Dakar. Patients and methodsWe retrospectively studied 90 patients presenting with of IE, hospitalized between January 2005 and February 2011. The diagnostic criteria for IE were modified Duke University criteria. We selected in our study population, patients with vascular complications. ResultsSeventeen patients (18.8%) presented with one or more vascular complications of IE: eight male and nine female patients, with a mean age of 28 years. Infective endocarditis occurred on an abnormal valve in 15 cases. We identified 22 vascular lesions: ten neurological complications, seven arterial complications in the limbs, two myocardial infarctions, two cases of pulmonary embolism, and one splenic infarction. The vascular complication revealed an IE in seven cases. The vascular complication occurred during antibiotic treatment, in 15 cases including seven cases before the 14th day, nine of the 17 patients died. Death was related to vascular complications in six cases, in one case it was related to septic shock. ConclusionVascular complications of IE are frequent, the most common are neurological. Their prevention requires early and adequate management of IE.
