The debilitating pain of trigeminal neuralgia often necessitates neurosurgical intervention via percutaneous transovale cannulation. While most percutaneous treatments of trigeminal neuralgia are successful, severe adverse events resulting from failure to properly cannulate the foramen ovale (FO) have been reported. With regard to specific targeting of particular trigeminal divisions (ie, V1, V2, V3, and combinations thereof), operative techniques have been described; however, these descriptions have not included specific angulation data...

Percutaneous radiofrequency thermocoagulation (RFT) of the Gasserian ganglion is an effective treatment for primary trigeminal neuralgia (pTN). Currently Hartel anterior approach is the most commonly used method to access the Gasserian ganglion. However, this approach is associated with high recurrence rate and technical difficulties in certain patients with foramen ovale (FO) anatomical variations. In the present study, we assessed the feasibility of accessing the Gasserian ganglion through the FO from a mandibular angle under computed tomography (CT) and neuronavigation guidance...

BACKGROUND AND PURPOSE: Left atrial dysfunction has been reported in patients with patent foramen ovale (PFO). Here we investigated the role of left atrial dysfunction in the development of embolic stroke in patients with PFO. METHODS: We identified consecutive patients with embolic stroke of undetermined sources except for PFO (PFO+ESUS). Healthy subjects with PFO served as controls (PFO+control). A stratified analysis by 10-year age group and an age- and sex- matching analysis were performed to compare echocardiographic markers between groups...

The carotid canal (CC) located in the petrous temporal bone transmits the internal carotid artery, internal carotid venous plexus and sympathetic nerve plexus from the neck into the cranial cavity. It is an accessible passage into the cranial cavity and is considered an important anatomical landmark for neurosurgeons. The aim of this study was to investigate the topographical, morphometric and morphological parameters of the CC. An examination of the CC and related adjacent structures in 81 dry skull specimens was performed...

The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n Heat (TH), TC System (TC) and the Tagger's Hybrid Technique (TG).In the sequence, the teeth were sectioned at 2mm and 4mm from the foramen and images were taken to measure the percentage of canal area filled with the obturation materials as well as void spaces...

An 80-year-old female presented with progressive breathlessness, worse on sitting or standing and relieved by lying flat. Subsequent investigations identified a patent foramen ovale (PFO) with right-to-left flow across the interatrial septum (IAS). A diagnosis of platypnoea orthodeoxia syndrome secondary to inter-atrial shunting was made. Technical features precluded a percutaneous PFO closure so an open surgical repair was performed with complete resolution of symptoms. We discuss the pathophysiology and management of platypnoea orthodeoxia syndrome...

A female Southern black rhinoceros ( Diceros bicornis minor) calf died unexpectedly at less than 12 hr of age, after an uncomplicated birth and uneventful early postpartum period. Gross necropsy revealed a 15-cm full thickness cleft palate, a patent foramen ovale, and four septal defects ranging from 0.3 to 1 cm in diameter. Histologic findings did not reveal any significant abnormalities. Karyotyping did not indicate any significant numerical or structural chromosomal abnormalities.

OBJECTIVE: To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. STUDY DESIGN: We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major...

PURPOSE: Malignant peripheral nerve sheath tumors are extremely rare in the general population and display a predilection for metastasis to the lungs. Here, we present a rare case of a malignant peripheral nerve sheath tumor located in the paraspinal region and highlight the importance of preoperative biopsy in diagnosis of spinal epidural peripheral nerve sheath tumors. METHODS: We describe the clinical course of the patient as well as the radiological and pathological findings of the tumor...

INTRODUCTION: Inhomogeneity of lung attenuation pattern is observed in high resolution chest computed tomography (HRCT) in some IPAH patients despite lack of interstitial lung disease. Such radiological changes are described either as ill-defined centrilobular nodules (CN) or as focal ground glass opacities (FGGO). There is no consensus in the literature, whether they indicate the distinct type of IPAH, or pulmonary venoocclusive disease (PVOD) with subtle radiological changes. Thus the aim of the present pilot study was to assess the frequency and clinical significance of inhomogenic lung attenuation pattern in IPAH...

OBJECTIVE: Global racial variability in human development can lead to differences in size of fetal cardiac structures during gestation. Our objective is to establish normal reference ranges of fetal cardiac dimensions between 20 and 34 weeks from fetal echocardiograms recorded at a single center in China. METHODS: A prospective cross-sectional study was undertaken on single pregnancies with normal fetuses of varying gestational ages (GAs). A total of 4396 normal fetuses were divided into 15 groups from 20 to 34 weeks according to the GA...

OBJECTIVE: Hemangiomas are tumors most commonly encountered in pediatric patients, and are frequently treated with propranolol. However, there are currently no standard methods for evaluating cardiac function in patients prior to propranolol treatment. The present study was designed to aid in the evaluation of pretreatment cardiac and effects of propranolol on vital signs in pediatric hemangioma patients. METHODS: A pediatric oncology specialist and a pediatric cardiology specialist examined all patients prior to initiation of propranolol treatment...

Damage to the dorsomedial thalamus usually leads to impaired episodic memory, attention, and executive function, but the role of the dorsomedial thalamus in memory processing is still not fully understood. Clinical evidence is inconclusive about whether dorsomedial thalamic damage impairs recall or whether it impairs recognition. I report a unique patient who suffered a cardioembolic stroke in the paramedian artery territory, caused by a patent foramen ovale. He was left with a chronic ischemic lesion centered in the parvocellular and, to a lesser extent, the magnocellular portions of the left dorsomedial thalamic nucleus, and marginally involving the midline and intralaminar nuclei...

BACKGROUND: Thromboembolism-in-transit straddling a patent foramen ovale (PFO) is a rare condition that requires urgent surgical intervention to prevent arterial emboli. CASE REPORT: We present the case of a 42-year-old female who presented with a symptomatic pulmonary embolism. Echocardiography identified a PFO, with a bridging thrombus-in-transit and evidence of right ventricular strain. Urgent surgery was performed because of the risk of systemic embolism. A large thrombus was identified during biatrial exploration...

PURPOSE: To explore significance, management, and outcomes of central venous catheter (CVC) tip-associated thrombi incidentally detected on echocardiography. MATERIALS AND METHODS: Echocardiogram data from all patients with CVCs from October 2009 to June 2011 were reviewed (N = 170). Patients with CVC tip-associated thrombi were selected (n = 49). Echocardiograms were reviewed for ejection fraction, presence of patent foramen ovale (PFO), presence of other intracardiac shunts, and mean thrombus size...

OBJECTIVES: This study reviewed a series of patients treated with transcatheter closure of septal defect to treat platypnea-orthodeoxia syndrome, with specific attention to septal characteristics and device choice. BACKGROUND: Platypnea-orthodeoxia syndrome is an uncommon condition characterized by positional dyspnea and hypoxemia due to intracardiac right-to-left shunting through a patent foramen ovale (PFO), an atrial septal defect, or pulmonary arteriovenous malformations...
