[Successful surgical management of aortico-left ventricular tunnel using modern noninvasive diagnostic imaging methods].

Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the aorta to the left ventricle. The authors present the case of a 14-year-old boy with aortico-left ventricular tunnel in whom the aortic orifice arose from the right aortic sinus and was closed by a pericardial patch. The diagnosis was confirmed by combined two-dimensional and real time three-dimensional echocardiogram and magnetic resonance imaging.

[New results in the research of the biomechanics of the venous system].

The upright posture of man had been a major evolutional challenge. The mechanisms responsible for orthostatic tolerance mostly affect the venous system. In this paper, we discuss new results regarding the biomechanics of the venous system highlighting a rather neglected field, the biomechanical properties of the vein wall.

Treatment of posttraumatic high-flow priapism in 8-year-old boy with percutaneous ultrasound-guided thrombin injection.

Treatment of high-flow priapism varies and has included transcatheter embolization when conservative approaches fail. We present the case of an 8-year-old boy with high-flow priapism, who was treated with ultrasound-guided thrombin injection because of encouraging experience with the method obtained when treating aneurysms and pseudoaneurysms. This procedure appears to be a useful alternative to transcatheter embolization and results in no radiation exposure.
