Myeloid sarcoma without circulating leukemia mimicking gastrointestinal malignancy and lymphoma.

We present an unusual case of myeloid sarcoma with ascites and abdominal pain in which initial clinical, laboratory, and imaging studies suggested a gastrointestinal malignancy or lymphoma. Subsequent detection of leukemic ascites and blasts in a gastric, small bowel, and skin biopsy supported a diagnosis of myeloid sarcoma. Bone marrow biopsy revealed 15% blasts, and cytogenetics with an inversion 16 rearrangement was diagnostic of acute myeloid leukemia (AML).

Short- and long-term outcomes in octogenarian patients undergoing off-pump coronary artery bypass grafting compared with on-pump coronary artery bypass grafting.

Objective: : Coronary artery bypass grafting (CAB) on elderly patients presenting with multivessel coronary artery disease has become routine in modern day operating rooms. The aim of our study was to compare short- and long-term outcomes in octogenarian patients undergoing off-pump CAB (OPCAB) versus on-pump CAB (ONCAB).

Methods: : A propensity-adjusted, retrospective review of patients older than 80 years who underwent primary CAB from January 1996 to September 2008 at our institution's hospitals was performed.

Impact of preoperative renal dysfunction on long-term survival for patients undergoing aortic valve replacement.

Background: The impact of the degrees of renal dysfunction (RD) after aortic valve replacement (AVR) has not been well described. The purpose of this study was to compare patients undergoing AVR with a range of renal function from normal to dialysis-dependence.

Methods: A retrospective review of 2,408 patients undergoing AVR with or without coronary artery bypass graft surgery (CABG) from January 1996 to March 2009 was performed.

Long-term survival for patients with preoperative renal failure undergoing bioprosthetic or mechanical valve replacement.

Background: The objective of this study was to assess short-term and long-term outcomes after valve replacement with biologic or mechanical prostheses in patients with preoperative end-stage renal disease on chronic dialysis.

Methods: A retrospective review of patients with end-stage renal disease undergoing valve replacement from January 1996 through March 2008 at Emory Healthcare Hospitals was performed. Outcomes were compared using χ(2) tests and 2-sample t tests.

Outcomes of off-pump aortic valve bypass surgery for the relief of aortic stenosis in adults.

Background: Elderly patients with aortic stenosis presenting for an aortic valve replacement with a hostile ascending aorta remain a challenging patient cohort. The purpose of this study was to assess outcomes after the use of an aortic valve bypass performed without cardiopulmonary bypass.

Methods: A retrospective review was performed on 21 high-risk patients who underwent primary, isolated aortic valve bypass from September 2004 to June 2009 at Emory Healthcare Hospitals.
