Long‐term outcomes of percutaneous closure of coronary artery fistulae in the adult: A single‐center experience

Ashish H. Shah, Mark Osten, Lee Benson, Sami Alnasser, more

Catheterization and Cardiovascular Interventions > 95 > 5 > 939 - 948

Coronary artery fistulae (CAF) are rare congenital cardiac abnormalities. With increasing age, patients with moderate to large fistulae are likely to become symptomatic and encounter complications. Percutaneous closure has been accepted as a safe and effective alternative to surgery; however, information regarding long‐term outcomes in adult patients after transcatheter closure is limited. Methods...

Analysis of intra-operative variables as predictors of 30-day readmission in patients undergoing glioma surgery at a single center

Iahn Cajigas, Anil K. Mahavadi, Ashish H. Shah, Veronica Borowy, more

Journal of Neuro-Oncology > 2019 > 145 > 3 > 509-518

Purpose Reducing the time from surgery to adjuvant chemoradiation, by decreasing unnecessary readmissions, is paramount for patients undergoing glioma surgery. The effects of intraoperative risk factors on 30-day readmission rates for such patients is currently unclear. We utilized a predictive model-driven approach to assess the impact of intraoperative factors on 30-day readmission rates for the...

Comparing invasive with MRI‐derived intracranial pressure measurements in healthy elderly and brain trauma cases: A pilot study

Ritambhar Burman, Ashish H. Shah, Ronald Benveniste, George Jimsheleishvili, more

Journal of Magnetic Resonance Imaging > 50 > 3 > 975 - 981

Background Intracranial pressure (ICP) is an important physiological parameter in several neurological disorders. Considerable effort has been made to measure ICP noninvasively. MR‐based ICP (MR‐ICP) is a nonempirical method based on principles of cerebrospinal fluid (CSF) physiology, where ICP is obtained from measurements of blood and CSF flows to and from the cranium during the cardiac cycle....

The use of dehydrated amniotic membrane allograft for augmentation of dural repair in transsphenoidal endoscopic endonasal resection of pituitary adenomas

Daniel G. Eichberg, Angela M. Richardson, G. Damian Brusko, Sheikh C. Ali, more

Acta Neurochirurgica > 2019 > 161 > 10 > 2117-2122

Background In transsphenoidal endoscopic endonasal surgery (TEES), watertight separation of the sinonasal cavity and intracranial compartment is the primary goal of closure. However, even when meticulous closure technique is implemented, cerebrospinal fluid (CSF) leaks, dural scarring, and meningitis may result. Particularly when intraoperative CSF leak occurs, materials that facilitate the creation...

Predictive modeling of brain tumor laser ablation dynamics

Walter J. Jermakowicz, Anil K. Mahavadi, Iahn Cajigas, Lia Dan, more

Journal of Neuro-Oncology > 2019 > 144 > 1 > 193-203

Introduction Laser interstitial thermal therapy (LITT) is a novel MR thermometry-guided thermoablative tool revolutionizing the clinical management of brain tumors. A limitation of LITT is our inability to estimate a priori how tissues will respond to thermal energy, which hinders treatment planning and delivery. The aim of this study was to determine whether brain tumor LITT ablation dynamics may...

Enhancing nodular lesions in Chiari II malformations in the setting of persistent hindbrain herniation: case report and literature review

Alexa Semonche, Ashish H. Shah, Daniel G. Eichberg, Sakir H. Gultekin, more

Child's Nervous System > 2019 > 35 > 7 > 1239-1243

Background Chiari II malformation includes concomitant cerebellar tonsillar herniation, hydrocephalus, and myelomeningocele. Rarely, pediatric patients with persistent hindbrain herniation develop a new enhancing nodule at the cervicomedullary junction as adults. These new lesions may be suspicious for neoplastic growth, but it remains unclear if neurosurgical intervention is necessary. Case Report...

Extracranial extra-CNS spread of embryonal tumor with multilayered rosettes (ETMR): case series and systematic review

Ashish H. Shah, Ziad Khatib, Toba Niazi

Child's Nervous System > 2018 > 34 > 4 > 649-654

Background Embryonal tumors with multilayered rosettes (ETMR) is a rare variant of embryonal tumor of infancy with nearly 200 cases reported in the literature. Leptomeningeal spread of this tumor is well known; however, extracranial metastasis has been sparsely reported in the literature. Methods Our study was divided into two sections: (1) We conducted a retrospective review of our patient series...

Transcatheter valve implantation for right atrium‐to‐right ventricle conduit obstruction or regurgitation after modified Björk–fontan procedure

Ashish H. Shah, Eric M. Horlick, Andreas Eicken, Jeremy D. Asnes, more

Catheterization and Cardiovascular Interventions > 89 > 2 > 298 - 305

Background The most common reason for reintervention after a Björk modification of the Fontan procedure, in which the right ventricle (RV) is incorporated into the pulmonary circulation by connecting the right atrial (RA) appendage to the RV directly or with an extra‐anatomic graft, is obstruction or regurgitation of the RA–RV connection. Transcatheter implantation of a valved stent is an appealing...

Presurgical thalamocortical connectivity is associated with response to vagus nerve stimulation in children with intractable epilepsy

George M. Ibrahim, Priya Sharma, Ann Hyslop, Magno R. Guillen, more

NeuroImage: Clinical > 2017 > 16 > C > 634-642

Although chronic vagus nerve stimulation (VNS) is an established treatment for medically-intractable childhood epilepsy, there is considerable heterogeneity in seizure response and little data are available to pre-operatively identify patients who may benefit from treatment. Since the therapeutic effect of VNS may be mediated by afferent projections to the thalamus, we tested the hypothesis that intrinsic...

Worsening Hypoxia Post Lung Transplant: What has Changed?

Ashish H. Shah, Andrew Leventhal, Eric Horlick, Erwin Oechslin, more

Heart, Lung and Circulation > 2016 > 25 > 11 > e155-e157

Platypnoea-orthodeoxia is a rare, but under-diagnosed clinical entity, characterised by postural hypoxia and breathlessness. Underlying pathology is inter-atrial shunt or pulmonary vascular malformation, but what anatomical distortion / physiological alterations initiates right to left shunt, usually against the pressure gradient remains unknown.

JACC: Cardiovascular Interventions > 2016 > 9 > 18 > 1928-1938

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.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...

Acute Thyrotoxicosis of Graves Disease Associated with Moyamoya Vasculopathy and Stroke in Latin American Women: A Case Series and Review of the Literature

Nirav H. Shah, Priyank Khandelwal, Gillian Gordon-Perue, Ashish H. Shah, more

World Neurosurgery > 2016 > 92 > C > 95-107

Moyamoya disease is a cerebral vasculopathy characterized by stenosis of the terminal internal carotid artery, proximal middle cerebral artery, and anterior cerebral artery. There is an association between moyamoya vasculopathy and Graves disease, primarily in Asian populations. Here, we present the largest series of non-Asian, predominantly Latino patients with moyamoya vasculopathy in the setting...

The Parable of the Errant Chest Drain in the Heart: Is There Only 1 Option?

Ashish H. Shah, Martin Simons, Hani Amad, Neilesh Soneji, more

The Annals of Thoracic Surgery > 2016 > 102 > 1 > 311-313

Accidental intraventricular placement of a pericardiocentesis catheter is a rare but well-recognized complication. Failure to achieve adequate hemostasis in the ventricular wall on removal of the catheter can potentially result in fatal consequences. Here we describe a case in which a chest drain (10.2F) accidentally entered into the right ventricle while attempting to drain pleural fluid, and the...

The role of brachytherapy in the treatment of glioblastoma multiforme

Eric Barbarite, Justin T. Sick, Emmanuel Berchmans, Amade Bregy, more

Neurosurgical Review > 2017 > 40 > 2 > 195-211

Brachytherapy (BT) for glioblastoma multiforme (GBM) involves the use of radioactive isotopes to deliver ionizing radiation directly into the tumor bed. Its application as a means to prolong survival in GBM patients over the past few decades has come with variable success. The objective of this review is to describe the utility of BT in GBM, and to report the outcomes and adverse events associated...
