Pimelodus (Pimelodidae) is a genus comprising a group of South American species with complex taxonomic relationships. Cytogenetics, polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP), and sequencing data of mitochondrial genes were analyzed to characterize 4 Pimelodus species: P. fur, P. heraldoi, P. maculatus, and Pimelodus sp.(More)
Venous ulcers in patients with post thrombotic syndromes are complex situations with multiple therapeutic options. They are responsible for high morbidity rates, conservative treatment is very slow and recurrences are very common. Deep venous reconstructive surgery is an alternative, but it should be based on the morphologic and functional aspects of the(More)
Leg ulcers constitute a highly prevalent pathology in society, and are particularly common in the Angiology and Vascular Surgery outpatient clinic. The prevalence of these patients in this Department result from the fact that 70% of them display superficial and/or deep venous insufficiency of the lower limbs. To address this problem and optimize the(More)
PURPOSE To study the short and long-term follow-up of patients with left main coronary artery disease (LMCAD) and age over 65 years, by comparing the results with patients under 65 years-old. METHODS Twenty-two patients with LMCAD and mean age of 69 +/- 3.5 years (group I) were underwent isolated coronary artery bypass grafting (CABG) and compared to 31(More)
The resection and reconstruction of the large venous vessels of the chest is a procedure intended to treat the symptoms of venous hypertension caused by the Superior Vena Cava Syndrome and to allow resection of mediastinal tumors that invade the superior vena cava (SVC) and the left and right innominate veins. We report four clinical cases of mediastinal(More)
INTRODUCTION Mycotic pseudoaneurysms are an infrequent complication of infective endocarditis; most cases are secondary to arterial trauma. The commonest site involved are the intracranial arteries, followed by the abdominal aorta and then the peripheral vessels. CASE PRESENTATION We report a case of a 36-year-old man, admitted in our institution for a(More)
OBJECTIVES To characterise liver dysfunction in patients with aortocaval fistula. DESIGN Retrospective study. MATERIALS All four patients operated on for aortocaval fistula between 1999 and 2003. Three were males with ruptured abdominal aortic aneurysm (AAA). One was a female who underwent lumbar disk surgery. Four patients operated on for ruptured AAA(More)
BACKGROUND Early recognition of heart disease in diabetics is a highly desirable goal, and diastolic dysfunction, one of its earliest manifestations, can be readily assessed by tissue Doppler imaging. We tested in normotensive diabetics without signs of coronary artery disease whether tissue Doppler imaging would improve the diagnosis of diastolic(More)
OBJECTIVES To retrospectively review the hybrid treatment of the aortic arch with supra-aortic debranching and endo- vascular stent-graft repair in a single institution. METHODS From 2007 to 2010, all patients submitted to aortic debranching procedures were entered into a prospective database analysis. For the present study, only patients with sealing(More)
