BACKGROUND Cardiopulmonary bypass (CPB) has pathophysiologic sequelae that may be more severe in high-risk subsets. We wanted to determine whether off-pump coronary bypass (OPCAB) could optimize outcomes. METHODS Our database of 242 OPCAB patients undergoing complete revascularization was compared to a base of 483 CABG patients undergoing CPB. Results(More)
Over a six year span, 41 patients with end stage renal disease (ESRD) were treated for 53 episodes of upper and lower gastrointestinal (UGI & LGI) hemorrhage. Thirty-two patients (78%) were diagnosed as having UGI bleeding and nine patients as having LGI bleeding. Mucosal inflammation of the esophagus, stomach and duodenum were the predominant etiologies of(More)
Although transvenous pacing is feasible in infants and children, uncertainty remains as to how to allow for future growth at the time of lead insertion. Accordingly, we retrospectively reviewed the relation between age and transvenous lead length. Standard posteroanterior chest roentgenograms were reviewed for 26 patients with transvenous pacemakers(More)
BACKGROUND Cardiopulmonary bypass and cardioplegic arrest result in known physiologic inflammatory, coagulopathic, and embolic states that may result in end-organ damage. Interest in off-pump complete coronary revascularization using sternotomy exposure is therefore increasing. METHODS Using specific surgical and anesthetic techniques, we have been able(More)
Alimentary tract duplications are unusual anomalies that may require surgical intervention in the neonate, infant, and occasionally in the older child. The clinical presentation of patients with alimentary tract duplications includes bleeding, abdominal pain, intussusception, and respiratory distress, or it may be an incidental finding on either abdominal(More)
HYPOTHESIS An experimental polymeric sealant (CoSeal [Cohesion Technologies, Palo Alto, Calif]) provides equivalent anastomotic sealing to Gelfoam (Upjohn, Kalamazoo, Mich)/thrombin during surgical placement of prosthetic vascular grafts. DESIGN Randomized controlled trial. SETTING Nine university-affiliated medical centers. PATIENTS One hundred(More)
Twelve patients with cor triatriatum sinistrum were treated over a 28-year period. Their ages ranged from 1 month to 7.5 years. Congestive heart failure was the most common presentation. Cardiac catheterization was performed on six of the 12 patients and a correct diagnosis of cor triatriatum was made on angiography in only four of the six. Of the remaining(More)
BACKGROUND Vesicoureteral reflux (VUR) is a common finding in children with urinary tract infection (UTI), mostly diagnosed by voiding retrograde cystogram (VCUG). Children with VUR are at higher risk of renal damage with recurrent infections. Detecting VUR and renal scarring currently depends on imaging modalities with interventional invasive diagnostic(More)
BACKGROUND Redo coronary surgery in patients with patent internal mammary artery (IMA) grafts may be hazardous. A thoracotomy approach has been used to graft the circumflex branches to avoid injury from sternal re-entry. Combining this approach with off-pump revascularization techniques may be useful. METHODS Seven consecutive patients who had undergone(More)
OBJECTIVES Considering the relation between prematurity andasphyxia and also renal failure in neonates, the aim of this study was to determine the effect of aminophyllinein urine and serum indices of renal failure and consequently its prevention, in Premature Infants with asphyxia in Esfahan-lran. METHODS In this descriptive clinical trial study, 22(More)
