An alternate solution for the treatment of ascending aortic aneurysms: the wrapping technique
Tagarakis, G. I.; Karangelis, D.; Baddour, A. J.; Daskalopoulos, M. E.; Liouras, V. T.; Papadopoulos, D.; Stamoulis, K.; Lampoura, S. S.; Tsilimingas, N. B. (2010)Background: The aortic Dacron wrapping technique is a surgical technique used under certain circumstances in cases of ascending aorta dilatation. Herein, we are presenting our experience on the method performed on multimorbid ... -
Colonic Ischemia After Endovascular Exclusion of an Aortoiliac Aneurysm Using an Iliac Branch Device
Sfyroeras, G. S.; Koutsias, S.; Karathanos, C.; Stamoulis, K.; Giannoukas, A. D. (2010)Purpose: To present the first case of colonic ischemia (CI) after endovascular exclusion of an aortoiliac aneurysm using an iliac branch device (IBD). Case report: A 69-year-old male patient with an abdominal aortic and ... -
Failure analysis and fatigue life assessment of a redesigned aircraft landing gear component
Panagiotopoulos, D. I.; Stamoulis, K. (2013)The present study deals with the failure analysis, the redesign and the fatigue life assessment of a rod end component of the North American T-2 jet trainer aircraft, nose landing gear (NLG) system. The rod ends suffer ... -
Feasibility and safety of radical cystectomy under combined spinal and epidural anesthesia in octogenarian patients with ASA score >= 3: A case series
Tzortzis, V.; Dimitropoulos, K.; Karatzas, A.; Zachos, I.; Stamoulis, K.; Melekos, M.; Gravas, S. (2015)Introduction: This study evaluated the feasibility and safety of open radical cystectomy (RC) under combined regional anesthesia (CRA) in high-risk octogenarian patients. Methods: We retrospectively evaluated the medical ... -
Hybrid procedures for the treatment of multi-focal ipsilateral internal carotid and proximal common carotid or innominate artery lesions
Karathanos, C.; Sfyroeras, G. S.; Stamoulis, K.; Drakou, A.; Vretzakis, G.; Giannoukas, A. D. (2011)We report three cases with concomitant ipsilateral proximal common carotid and internal carotid artery stenosis treated in one stage with carotid endarterectomy and retrograde primary stenting of the common carotid artery. ... -
Monitoring of brain oxygen saturation (INVOS) in a protocol to direct blood transfusions during cardiac surgery: a prospective randomized clinical trial
Vretzakis, G.; Georgopoulou, S.; Stamoulis, K.; Tassoudis, V.; Mikroulis, D.; Giannoukas, A.; Tsilimingas, N.; Karanikolas, M. (2013)Background: Blood transfusions are common in cardiac surgery, but have been associated with increased morbidity and long-term mortality. Efforts to reduce blood product use during cardiac surgery include fluid restriction ... -
Poland's syndrome and recurrent pneumothorax: is there a connection?
Tagarakis, G. I.; Karangelis, D.; Tsantsaridou, A.; Tsolaki, F.; Daskalopoulos, M. E.; Hevas, A.; Kyriakaki, K.; Stamoulis, K.; Lampoura, S.; Tsilimingas, N. B. (2011)Aim. To investigate the possible connection of Poland's syndrome with the presence of lung bullae and, thus, with an increased risk for recurrent pneumothorax. Patients-methods. Two male patients, aged 19 and 21 years ... -
A second gradient elasto-plastic model for fatigue of small-scale metal components
Stamoulis, K.; Giannakopoulos, A. E. (2010)Purpose - As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behavior becomes size dependent and thus, the classical elasticity solutions cannot be expected to hold. In particular, ... -
Size effects on strength, toughness and fatigue crack growth of gradient elastic solids
Stamoulis, K.; Giannakopoulos, A. E. (2008)The present study investigates the microstructural size effect on the strength of a bar under axial loading, and on the toughness and crack growth of a beam under three-point bending within the framework of strain gradient ... -
Structural analysis of gradient elastic components
Giannakopoulos, A. E.; Stamoulis, K. (2007)The present study investigates the size effects in the problems of cantilever beam bending and cracked bar tension within the gradient elasticity framework. Analytical solutions for metrics that characterize both the ... -
A study of size effects and length scales in fracture and fatigue of metals by second gradient modelling
Stamoulis, K.; Giannakopoulos, A. E. (2012)As the dimensions of structures are scaled down to the micro- and nano-domains, the mechanical behaviour becomes size dependent and thus, we cannot expect the classical elasticity solutions to hold. In particular, recent ... -
West Nile virus outbreak in humans, Greece, 2012: third consecutive year of local transmission
Pervanidou, D.; Detsis, M.; Danis, K.; Mellou, K.; Papanikolaou, E.; Terzaki, I.; Baka, A.; Veneti, L.; Vakali, A.; Dougas, G.; Politis, C.; Stamoulis, K.; Tsiodras, S.; Georgakopoulou, T.; Papa, A.; Tsakris, A.; Kremastinou, J.; Hadjichristodoulou, C. (2014)In 2010, the first outbreak of West Nile virus (WNV) infection in Greece was recorded, the largest in Europe since 1996. After 2010, outbreaks continued to occur in different areas of the country. Enhanced surveillance was ...
