Difficulty of tracheal intubation is caused by many reasons and among them tracheal rupture is an infrequent factor. Tracheal rupture leads to higher mortality and poorer prognosis especial for closed tracheal rupture which is hard to early diagnose and is generally fatal. We described a case of a 34-year-old narcose man after a car accident that accepted twice unsuccessful tracheal intubation ...

Sinus of Valsalva aneurysm (SVA) is an uncommon anomaly of the aorta. Rupture of SVA often precipitates dramatic clinical complications, including heart failures. Right SVAs are the most common type, and when they rupture, they usually rupture into the right ventricle or right atrium. Rupture into left ventricle or interventricular septum is rare. Herein, we report a case of right SVA rupture w...

BACKGROUND Uterine rupture classically presents with severe abdominal pain, loss of fetal station, vaginal bleeding, and shock. CASE PRESENTATION We present a case of uterine rupture presenting as significant urinary retention that occurred following a second trimester abortion induced with mifepristone and misoprostol. Uterine rupture was discovered unexpectedly on diagnostic laparoscopy. Th...

Ventricular free wall rupture is a rare, usually fatal complication of acute myocardial infarction. Subacute free wall rupture with pseudoaneurysm formation is even rarer, but may be associated with a chance of survival if surgery is performed expeditiously. Although rupture of the left ventricle is more common, right-sided rupture has also been reported. We report an unusual case of post-infar...

BACKGROUND Plaque rupture may be present in the peripheral arteries of the patients at high risk for cardiovascular events and is possibly associated with vascular vulnerability. METHODS AND RESULTS One hundred one iliofemoral arteries from 101 patients undergoing angioplasty were studied. Intravascular ultrasound imaging was performed before intervention. Plaque rupture was defined as presen...

Dynamic force spectroscopy of single molecules is described by a model that predicts a distribution of rupture forces, the corresponding mean rupture force, and variance, which are all amenable to experimental tests. The distribution has a pronounced asymmetry, which has recently been observed experimentally. The mean rupture force follows a (lnV)2/3 dependence on the pulling velocity, V, and d...

Late aortic rupture following successful endovascular repair of abdominal aortic aneurysm still does occur. It represents the ultimate failure of endovascular aortic repair of abdominal aortic aneurysm (EVAR) and subjects patients to equivalent risk of death as de novo rupture. Unfortunately, it is difficult to identify patients at risk for post-EVAR rupture as many present with aortic rupture ...

The 10-20% incidence of cardiac rupture in acute fatal myocardial infarction has not changed in the past century, and little is known about its pathophysiology. To determine whether expansion acute dilatation and thinning of the area of infarction not explained by resorption of necrotic tissue may be a variable predictive for rupture, we studied 110 consecutive autopsied patients who died of ac...

We examine the long-period near-source ground motions from simulations of M 7.4 events on a strike-slip fault using kinematic ruptures with rupture speeds that range from subshear speeds through intersonic speeds to supersonic speeds. The strong along-strike shear-wave directivity present in scenarios with subshear rupture speeds disappears in the scenarios with ruptures propagating faster than...
