Parosteal lipoma is an extremely rare benign tumor that is composed mainly of mature adipose tissue, and it has an intimate relationship to the underlying periosteal bone. We believe that only three cases have been previously reported that have described parosteal lipoma of the rib. Although parosteal lipoma is asymptomatic, motor and sensory function(More)
We evaluated the safety and stability of the less-invasive submuscular bar fixation method in the Nuss procedure. One hundred and thirteen patients undergoing the Nuss procedure were divided into three groups according to the bar fixation technique employed. Group 1 consisted of 25 patients who had undergone bilateral pericostal bar fixation, group 2(More)
The morbidity and mortality of anastomotic complications after esophagectomy have gradually decreased in recent years. However, swallowing difficulties and reflux continue to burden patients jeopardizing their quality of life. In the present study we performed endoscopic evaluation of the outcomes of esophagogastrostomy by analyzing the presence of(More)
The aim of this study was to compare clinical outcomes in pectus excavatum patients undergoing a Ravitch operation with those undergoing a Nuss procedure. Retrospective study was conducted on one hundred and twenty three patients who underwent Ravitch operation (n=16) and Nuss procedure (n=107) between 1995 and 2002. Mean age of the patients was 7.9+/-6.2(More)
Infradiaphragmatic extralobar pulmonary sequestration is an extremely rare congenital malformation. It is more frequently diagnosed in the antenatal period due to routine ultrasonic examination of the fetus or in the first 6 months of life, though on rare occasions it is discovered incidentally in adults. A 32-yr-old man presenting with epigastric(More)
The purpose of this study was to estimate the possibilities of an acellular matrix using a modified acellularization protocol, which circumvents immunological, microbiological, and physiological barriers. We treated porcine subclavian arteries with various reagents to construct acellular grafts. Afterwards, these grafts were interposed in a mongrel dogs'(More)
Guidelines for surgical management of posttraumatic pectus excavatum have not been established due to the variable clinical manifestations and limited number of cases. A 34-year-old man who was involved in a truck-mixer vehicle crash 6 months previously complained of a depressed anterior chest wall deformity. The patient had successfully undergone(More)
The goal of this study was to compare the effects of different reperfusion methods on N-terminal B-type natriuretic peptide (NT-proBNP) in percutaneous transluminal coronary angioplasty (PTCA) or off-pump coronary artery bypass (OPCAB) patients. Fifty subjects were enrolled in the study, 32 patients received PTCA and 18 OPCAB. An NT-proBNP measurement was(More)
Advances in medicine and technology have increased brachial artery utilization for diagnostic and interventional radiology. Hence, detection and assessment of variations in upper extremity vasculature are important regardless of the low surgical intervention rate in the upper extremity. Anomalies of the upper extremity artery are infrequently reported, and(More)
