Abstract

Total ankle arthroplasty (TAA) is an evolving option for treating ankle arthritis. We assessed the national trends in usage and perioperative outcomes of TAA in the United States. International Classification of Diseases, 9th revision (ICD-9), codes were used to search the National Hospital Discharge Survey database for TAA from 1997 to 2010. Patient demographics, comorbidities, hospitalization length, discharge disposition, blood transfusion, lower extremity deep vein thrombosis, pulmonary embolism, and mortality data were gathered. Trends were evaluated using linear regression with Pearson's correlation coefficient, and statistical comparisons were performed using Student's t test and z-test for proportions with significance at p = .05. We identified 120 patients with TAA. TAA demonstrated a positive correlation with time (r = 0.57), significantly increasing from 2.4 cases per 100,000 admissions from 1997 to 2003 to 3.5 cases per 100,000 from 2004 to 2010 (p = .04). The mean age was 57.8 (range 19 to 83) years. The mean number of comorbidities was 4.5 (range 1 to ≥7). Although patient age remained stable (p = .21), the mean number of comorbidities significantly increased from 4.0 from 1997 to 2003 to 4.8 from 2004 to 2010 (p ...Continue Reading

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
