Abstract

The aim of this study was to analyze factors influencing outcomes of surgical management for lower limb acute ischemia. A retrospective analysis of 490 thromboembolectomies performed in 468 patients was conducted. Perioperative and follow-up results were analyzed. Univariate and multivariate analysis of clinical variables and patients' characteristics for the risk of reocclusion, amputation and mortality at 2 years were performed. Statistical significance was defined as a P value <0.05. Cumulative reocclusion, amputation and mortality rates at 24 months were 22.6%, 14.3% and 42.8%, respectively. At univariate analysis, the factors associated with increased 2-year reocclusion rate were severity of clinical presentation, current smoking habit, arterial thrombosis rather than embolism, atrial fibrillation and the avoidance of completion angiography. All these factors except clinical presentation maintained significance at multivariate analysis. Factors associated with increased 2-year amputation rate at univariate analysis included severity of clinical presentation, smoke, arterial thrombosis, atrial fibrillation and valvulopathy. All these factors except clinical presentation and valvular defects maintained significance at multiv...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
