Aim: The aim of our study, to evaluate the patients with complete or incomplete uterine rupture which occurred during pregnancy retrospectively and to analyze and present of the risk factors, maternal and perinatal outcomes, and complications. Method: Sixty one patients diagnosed as uterine rupture were investigated retrospectively in our clinic between 1999 and 2009. Result: The incidence of u...
[1] Earthquake ruptures are modeled as dynamically propagating shear cracks with the aim of gaining insight into the physical mechanisms governing their arrest or, otherwise, the often-observed variations in rupture speeds. Fault bends have been proposed as being the main cause for these variations. Following this line of reasoning, the existence of deviations from fault planarity is chosen as ...
RUPTURE iS the usual cause of death in cases of dissecting aneurysm of the aorta in the acute stage. In Sheenan's series of 300 cases (1934) the pericardium was the commonest site of rupture, the pleural cavity being next in frequency. Sheenan described only two cases that survived intrapleural rupture of a dissecting aneurysm, one for 17 days, the other 19 days, and in a review of 505 cases of...
BACKGROUND AND PURPOSE The natural history of unruptured intracranial aneurysms remains unclear, and management strategy is not well defined. METHODS From January 2003 to December 2012, we enrolled patients with aneurysm in our institution. In total, 2252 patients with 2897 aneurysms were eligible for analysis, and 1960 eligible aneurysms were conservatively managed. Precise 3-dimensional eva...
Rupture of hydatid liver cyst into biliary tree is frequent complications that involve the common hepatic duct, lobar biliary branches, the small intrahepatic bile ducts,but rarely rupture into common bile duct. The rupture of hydatid cyst is serious life threating event. The authors are reporting a case of total rupture of hydatid cyst of liver into common bile duct. A 50-year-old male patient...
Diaphragmatic rupture is a life-threatening condition. Diaphragmatic injuries are quite uncommon and often result from either blunt or penetrating trauma. Diaphragmatic ruptures are usually associated with abdominal trauma however, it can occur in isolation. Acute traumatic rupture of the diaphragm may go unnoticed and there is often a delay between the injury and the diagnosis. A comprehensive...
By its very nature, rupture of the atherosclerotic plaque is difficult to study directly in humans. A good animal model would help us not only to understand how rupture occurs but also to design and test treatments to prevent it from happening. However, several difficulties surround existing models of plaque rupture, including the need for radical interventions to produce the rupture, lack of d...
The 2013M8.3 Okhotsk earthquake involves two primary mechanisms of deep-focus earthquake rupture, mineral phase transformation of olivine to spinel and thermal shear instability. Backprojection imaging of broadband seismograms recorded by the North American and European networks indicates bilateral rupture toward NE and SSE. The rupture paths of the NE segment and other regional M7 earthquakes ...
During a 10-year period, we have encountered 6 patients (mean age, 61.2 years) with left ventricular rupture following mitral valve replacement, with an overall incidence of 1.8 percent. Four patients had early rupture, one had delayed rupture, and one had late rupture with a false aneurysm formation. Among four patients with early niptare, there were two patients with external repair by using ...
S U M M A R Y Knowledge of the rupture speed and spatial–temporal distribution of energy radiation of earthquakes is important for earthquake physics. Backprojection of teleseismic waves is commonly used to image the rupture process of large events. The conventional backprojection method typically performs temporal and spatial averaging to obtain reliable rupture features. We present an iterati...
