Background & Importance: Primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. Secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. We review and discuss the pathophysiology and the literature ...

To assess whether spontaneous coronary artery spasm in patients with variant angina results from local coronary hyperreactivity to a generalized constrictor stimulus or from a stimulus generated only at the site of the hyperreactive segment, the behavior of spastic and nonspastic coronary segments was studied in six patients with variant angina in whom focal coronary spasm developed spontaneous...

AIMS Contrast-guided axillary vein puncture is commonly used for pacemaker or defibrillator lead implantation. Venous spasm during contrast-guided axillary vein puncture has been reported rarely. We investigated the incidence of venous spasm during contrast-guided axillary vein puncture and the impact of venous spasm on axillary vein puncture. METHODS AND RESULTS Seventy-four consecutive pati...

Introduction:  Biliary atresia (BA) is the most common cause of neonatal jaundice, for which surgery is indicated. It may lead to portal hypertension and esophageal varices. Sometimes, BA is related to other congenital anomalies and malformation, while a coexistence of BA with facial hemangioma has not been reported, yet. Infantile hemangioma is a childhood benign vascular tumor. Beta bloc...

OBJECTIVES The aim of this study was to investigate the conformational change of arterial structure in the vasospastic lesion with optical coherence tomography. BACKGROUND Coronary artery spasm plays an important role in the pathogenesis of ischemic heart diseases. The conformational change of each arterial layer during vasospasm has not been studied in detail. METHODS We assessed 19 corona...

In this paper, a new technique (SPASM) based on a 3DASM is presented for automatic segmentation of cardiac MRI image data sets consisting of multiple planes with different orientations, and with large undersampled regions. SPASM was applied to sparsely sampled and radially oriented cardiac LV image data. Performance of SPASM has been compared to results from other methods reported in literature...
