BACKGROUND AND PURPOSE MR imaging is currently not used to evaluate CSF flow changes due to short-lasting physiological maneuvers. The purpose of this study was to evaluate the ability of MR imaging to assess the CSF flow response to a Valsalva maneuver in healthy participants. MATERIALS AND METHODS A cardiac-gated fast cine-PC sequence with ≤15-second acquisition time was used to assess CSF ...

Fig. 1. (A) CT scan image. CT scan shows giant non-coronary sinus of Valsalva aneurysm with neighbouring structures. Arrows indicate closed aortic valves. Ao: aorta, NC-SVA: non-coronary sinus of Valsalva aneurysm, LV: left ventricle, PA: pulmonary artery. (B) TEE image. Trans-oesophageal echocardiography shows aortic cusps level image of sinus of Valsalva aneurysm. *Arrows show aortic cusps, *...

PURPOSE To determine effectiveness of Valsalva maneuver and standing position on scrotal color Doppler ultrasound (CDU) for the varicocele diagnosis. MATERIALS AND METHODS We reviewed the physical examination and CDU finding in 87 patients who visited National Police Hospital from January 2011 to April 2014. Diameters of pampiniform plexus were measured bilaterally during resting and Valsalva...

purpose : to report a case of purtscher retinopathy associated with valsalva retinopathy after car accident methods : a 54-year-old man presented with a sudden visual loss in his left eye after car accident. fundus examination of the left eye showed cotton-wool spots and retinal hemorrhages in the posterior pole associated with subhyaloid hemorrhage in macula. results : fundus examination showe...

OBJECTIVE A Valsalva maneuver is used clinically and on imaging in order to determine female pelvic organ prolapse. We have examined the potential confounding effect of levator co-activation at the time of a Valsalva maneuver and the impact of repetition with biofeedback instruction. METHODS Fifty nulliparous women at 36-38 weeks' gestation received 3D/4D translabial ultrasound investigation ...

in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

The Valsalva maneuver can be used as a noninvasive index of autonomic control of blood pressure and heart rate. The purpose of this investigation was to test the hypothesis that sympathetic mediated vasoconstriction, as referenced by hemodynamic responses during late phase II (phase IIb) of the Valsalva maneuver, is inhibited during whole body heating. Seven individuals (5 men, 2 women) perform...

We describe a case of ruptured aneurysm of the left coronary sinus of Valsalva diagnosed by transthoracic two-dimensional echocardiography. A very few cases with ruptured left sinus of Valsalva have been reported. We are reporting a rupture of the left sinus of Valsalva into the main pulmonary artery in a 40-year-old male diagnosed by transthoracic echocardiography.

Sinotubular junction reconstruction in reimplantation type of valve-sparing aortic procedure can present some problem when a Valsalva graft is used. Since in the Valsalva graft the sinotubular junction height is predetermined, correct matching with native commissures height can be difficult. We propose a method by which it is possible to create a new sinotubular junction in Valsalva graft witho...

Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complicatio...
