OBJECTIVE: The objective of treatment for polycystic liver disease is to reduce the liver volume and reduce or resolve compression symptoms such as abdominal fullness and abdominal pain due to hepatomegaly. Liver cysts are treated internally by puncture and aspiration of the cyst contents or hepatic artery embolization and surgically by cyst fenestration or hepatectomy, but no clear consensus has been reached concerning their selection. We introduced monoethanolamine oleate (EO) sclerotherapy therapy for liver cysts in 1999 and reported its effectiveness...

A 33-day-old infant with obstructed cor triatriatum sinister and partial anomalous pulmonary venous drainage presented with respiratory distress and fever. Her suprasystemic pulmonary hypertension was relieved by opening the connection to the right atrium using balloon atrial septoplasty and septostomy, and to the inferior chamber using balloon dilation of a fenestration in the dividing membrane. This enabled extubation and discharge, with elective surgical repair at 2 months. To our knowledge, this is the youngest patient to receive a catheter intervention for obstructed cor triatriatum sinister, providing relief of pulmonary hypertension and postponement of surgical repair...

BACKGROUND: In 2014, we published a series of articles in the Journal of Vascular Surgery that detailed the decrease in volume of open aneurysm repair (OAR) completed for abdominal aortic aneurysm (AAA) by vascular surgery trainees. At that time, only data points from 2000 through 2011 were available, and reliable predictions could only be made through 2015. Lack of data on endovascular aneurysm repair (EVAR) using fenestrated (FEVAR) and branched (BrEVAR) endografts also affected our findings...

BACKGROUND: Neuronavigation, the ability to perform real-time intra-operative guidance during cranial and/or spinal surgery, has increased both accuracy and safety in neurosurgery [2]. Cranial navigation of existing surgical instruments using Brainlab requires the use of an instrument adapter and clamp, which in our experience renders an endoscope 'top-heavy', difficult to manipulate, and the process of registration of the adapter quite time-consuming. METHODS: A Brainlab Disposable Stylet was used to navigate fenestration of an entrapped temporal horn in a pediatric case...

A facilitative transport system exists on the blood-brain barrier (BBB) that has been tacitly assumed to be a path for glutamate entry to the brain. However, glutamate is a non-essential amino acid whose brain content is much greater than plasma, and studies in vivo show that glutamate does not enter the brain in appreciable quantities except in those small regions with fenestrated capillaries (circumventricular organs). The situation became understandable when luminal (blood facing) and abluminal (brain facing) membranes were isolated and studied separately...

BACKGROUND: Polycystic liver disease (PLD) is a rare genetic disorder with progressive cyst growth as the primary phenotype. Therapy consists of volume reduction through invasive surgical or radiological procedures. In order to understand the process of treatment decision, our aim was to identify factors that increased the likelihood of treatment. STUDY DESIGN: We performed a cross-sectional study using an international population of PLD patients. We collected data on the following therapies: liver transplantation, resection, fenestration and aspiration sclerotherapy...

Most small-molecule inhibitors of voltage-gated ion channels display poor subtype specificity because they bind to highly conserved residues located in the channel's central cavity. Using a combined approach of scanning mutagenesis, electrophysiology, chemical ligand modification, chemical cross-linking, MS/MS-analyses and molecular modelling, we provide evidence for the binding site for adamantane derivatives and their putative access pathway in Kv7.1/KCNE1 channels. The adamantane compounds, exemplified by JNJ303, are highly potent gating modifiers that bind to fenestrations that become available when KCNE1 accessory subunits are bound to Kv7...

Since the introduction of fenestrated endovascular aneurysm repair (FEVAR) in 1996, great advances have been made in endograft development. Custom-made and off-the-shelf fenestrated and branched endografts have been used to treat patients with complex abdominal aortic and thoraco-abdominal aneurysms. Most experience has been gained with the Cook Zenith® fenestrated endograft (Cook Medical Inc., Limerick, Ireland). The Cook Zenith® endograft is customized with fenestrations, (fixed) inner or outer branches, or a combination of them, to cover a wide range of complex aneurysms...

BACKGROUND: Tuberosity healing correlates with clinical outcomes after hemiarthroplasty for 4-part proximal humeral fractures (4PHFs). We seek to examine variables that affect tuberosity healing. METHODS: This was a retrospective comparative study. At 1 year postoperatively, patients who underwent hemiarthroplasty for 4PHFs were divided into 2 groups: those with anatomically healed tuberosities and those with tuberosity nonunion. The primary variables included time between injury and surgery, prosthesis fenestration, cement mantle classification, and both vertical and horizontal tuberosity reduction...

A 22-year-old man had cerebral venous sinus thrombosis and his angiogram incidentally revealed an absent left common carotid artery with bovine origin of the left external carotid artery. There was also an associated low bifurcation of the right common carotid artery and basilar artery fenestration. The absence of a common carotid artery is a very rare angiographic finding, and an association with a bovine origin of the left external carotid artery has not been reported previously in the literature. Here we provide a description of the case along with a review of the literature and embryology...

A 78-year-old man complained of bilateral visual acuity loss. Optical coherence tomography examination showed bilateral macular schisis with fluid accumulation in the external retinal layers without vitreous traction. Fundus examination and fluorescein angiography were normal in both eyes. Both eyes were treated by phacoemulsification, intraocular lens implantation, and vitrectomy without laser, gas exchange, or retinal fenestration. Slow and progressive fluid resorption and improvement in VA were observed in both eyes...

We report an extremely rare case of fenestration of the supraclinoid internal carotid artery (ICA) diagnosed by magnetic resonance (MR) angiography. The smaller channel arose from the paraclinoid ICA aneurysmal dilatation, and the posterior communicating artery arose from the distal end of the fenestration. Careful observation of MR angiographic images, including source images, is important to detect rare arterial variations, and their identification on MR angiography is aided by the creation of partial maximum-intensity-projection images and partial volume-rendering images...

The ventriculus terminalis (VT) is a virtual cavity of the conus medullaris that appears during embryonic life. We presented a case with the cystic dilation of the ventriculus terminalis (CDVT) in a symptomatic patient. A 66-year-old female suffered from disturbance while walking evolving for the past 2 years. An MR image revealed a cystic dilatation of ventriculus terminalis. The patient experienced marked improvement of lower extremity strength by a fenestration of cyst and cyst-subarachnoid shunt. Treatment for asymptomatic patients seems to be the best conducted conservatively, whereas patients with focal neurological deficits seem to be best handled surgically...

BACKGROUND: We hypothesized that mean pulmonary artery pressure (PAP) detected on a pulmonary flow study may predict medium-term survival and right ventricular systolic pressure (RVSP) in patients with pulmonary atresia (PA), ventricular septal defect (VSD), and major aortopulmonary collateral arteries (MAPCAs). METHODS: Fifty patients with PA/VSD/MAPCAs underwent unifocalization between 2000 and 2013, and 40 of these patients had a pulmonary flow study since 2003...
