Background Arteriovenous fistula (AVF) formation is an uncommon clinical manifestation of arterial trauma. A delayed diagnosis of AVF of 15 years had been reported, underscoring the potential for missing these injuries. Patient Presentation A fifty years old male presented with left lower limb heaviness and pain associated with leg swelling, color changes, ulcerations and offensive discharge wi...

abstract   background: different methods of surgical treatment for acromioclavicular(ac) joint injury were considered in the literature. the purpose of the study was to compare intra- articular ac repair technique with the extra-articular coracoclavicular repair technique for the patients with rockwood type iii and vac joint injury when indicated.   methods: nineteen consecutive patients with r...

abstract background: renal insufficiency is a potential complication after infrarenal abdominal aortic aneurysm repair and is a significant risk factor for postoperative mortality and morbidity. the aim of this study was to analyze the effect of this risk factor, before and during operation. methods: in this prospective study, between 2003 and 2006, 45 patients underwent repair of an infrarenal...

PURPOSE Selective cerebral perfusion with the open proximal technique for thoracoabdominal aortic repair has not been conclusively validated because of its procedural complexity and unreliability. We report the clinical outcomes, particularly the cerebroneurological complications, of an open proximal procedure using selective cerebral perfusion. METHODS A retrospective chart review identified...

DATA SOURCES 1) All patients who were referred to a tertiary center with spontaneous CSF otorrhea, exposed middle cranial fossa d...

Duration Calculus (DC) is a real-time logic with measurement of duration of propositions in observation intervals. It is a highly expressive logic with continuous time behaviours (also called signals) as its models. Validity checking of DC is undecidable. We propose a method for validity checking of Duration Calculus by reduction to a sampled time version of this logic called well sampled Inter...
