BACKGROUND Pectoralis flaps are frequently used to treat poststernotomy mediastinitis. We compared the outcomes of omental transfer, an alternative treatment for mediastinitis, with those of pectoralis flaps. METHODS Patients treated for poststernotomy mediastinitis with isolated omental flaps (n = 21) were compared with a group of consecutive patients(More)
OBJECTIVES The outcomes of patients with metastatic melanoma are poor. Although prognostic models have been developed to predict the occurrence of pulmonary metastasis from cutaneous melanoma, few data exist to define the outcomes of these patients once metastasis has occurred. The objective of this study was to discriminate predictors of survival for(More)
BACKGROUND Post-sternotomy mediastinitis reduces survival after cardiac surgery, potentially further affected by details of mediastinal vascularized flap reconstruction. The aim of this study was to evaluate survival after different methods for sternal reconstruction in mediastinitis. METHODS Two hundred twenty-two adult cardiac surgery patients with(More)
Because high blood pressure in children is rare and most of these patients are asymptomatic, many are overlooked until they present with a hypertensive crisis or irreparable damage. Most children with renal artery stenosis are asymptomatic and the hypertension is detected only by blood pressure recording during physical examination. Angiography is the most(More)
From 1970 to 1990, 7564 patients with melanoma were seen at Duke University Cancer Center. Complete follow-up data were available in all patients. The estimated probability of a pulmonary metastasis developing 5, 10, or 20 years after initial diagnosis was 0.13, 0.19, and 0.30, respectively. Pulmonary metastases were documented in 945 patients (12%), these(More)
Positron emission tomography (PET), with the glucose analog F-18 fluoro-deoxyglucose (FDG), takes advantage of the enhanced glucose uptake observed in neoplastic cells. We examined whether the detection of preferential FDG uptake with PET permits differentiation between benign and malignant focal pulmonary lesions in patients with suspected primary or(More)
From 1970 until 1990, 8,958 cases of primary carcinoma of the lung were diagnosed at the Duke University Medical Center. During the same period, 126 patients (mean age, 53 +/- 13 years) were diagnosed with bronchial carcinoid. The overall survival was 78% for 5 years and 71% for 10 years. Surgical treatment in 106 patients included pneumonectomy (15),(More)
OBJECTIVES This study compared survival after percutaneous coronary intervention (PCI) with survival after coronary artery bypass graft surgery (CABG) among diabetics in the Veterans Affairs AWESOME (Angina With Extremely Serious Operative Mortality Evaluation) study randomized trial and registry of high-risk patients. BACKGROUND Previous studies indicate(More)
BACKGROUND Sternal wound infection (SWI) remains a devastating complication after cardiac surgery, decreasing long-term and short-term survival. In treating documented SWI, negative pressure wound therapy (NPWT) reduces wound edema and time to definitive closure and improves peristernal blood flow after internal mammary artery (IMA) harvesting. The authors(More)
BACKGROUND Whether biological or mechanical valves should be used in patients on chronic dialysis therapy remains to be clearly defined. METHODS A retrospective review was performed on 19 consecutive patients from our institution with end-stage renal disease on chronic peritoneal or hemodialysis undergoing aortic (n = 12), mitral (n = 5), or aortic-mitral(More)
