Neurosurgical Outcomes, Protocols, and Resource Management During Lockdown: Early Institutional Experience from One of the World's Largest COVID 19 Hotspots.

Background: As the COVID-19 pandemic surpasses 1 year, it is prudent to reflect on the challenges faced and the management strategies employed to tackle this overwhelming health care crisis. We undertook this study to validate our institutional protocols, which were formulated to cater to the change in volume and pattern of neurosurgical cases during the raging pandemic.

Methods: All admitted patients scheduled to undergo major neurosurgical intervention during the lockdown period (15 March 2020 to 15 September 2020) were included in the study.

Experience with FRED junior flow diverter in treatment of cerebral aneurysms at or distal to the circle of Willis.

This retrospective study was aimed at assessing our results of endovascular management using the FRED junior flow diverter in cerebral aneurysms at or distal to the circle of Willis. 12 patients with 15 small cerebral vessel aneurysms at or distal to the circle of Willis underwent endovascular treatment using the FRED junior flow diverter at two tertiary care centres in Mumbai, India. 12 of the 15 aneurysms were unruptured, one was treated in an acutely ruptured setting, while two, which had presented with SAH were initially treated with balloon assisted coiling and later treated in a staged manner with a flow diverter.

Endovascular Management of Vein of Galen Aneurysmal Malformations: A Retrospective Analysis over a 15-Year Period.

Objectives: This retrospective study was aimed at assessing our results of endovascular management in vein of Galen aneurysmal malformation (VGAM).

Materials And Methods: This is a retrospective study of 26 patients of VGAM who underwent endovascular treatment between 1998 and 2012. All patients underwent trans-arterial embolization.

Pattern of Emergent Head Computed Tomography Findings in a Tertiary Care Hospital during off Working Hours: Retrospective Analysis.

Introduction: Emergency head computed tomography (CT) is rising exponentially during off working hours due to evidence-based medicine, patient's expectation and desires, easy availability and apprehension of medico-legal cases, thereby raising health-care cost. There is huge gap in demand and supply of radiologist, especially during off working hours. There is need to know the pattern of emergency head findings.

A Study on the Clinical and Angiographic Spectrum of Spontaneous Extracranial Dissections in the Cerebral Vasculature.

Aim: To prospectively study the clinical profile, angiographic features, and functional outcomes, in consecutive cases of extracranial dissection seen at two tertiary stroke care centers in South India.

Materials And Methods: In this observational study, spanning 4 years (December 12-December 16), a total of 442 patients presented with an acute ischemic stroke/transient ischemic attack (TIA) at our study centers. 14/546 (3.

Diagnosing thoracic venous aneurysm: A contemporary imaging perspective.

Thoracic venous aneurysms are a rare clinical entity and contrast-enhanced computed tomography has been the cornerstone of their diagnosis. We are reporting a rare case of isolated left brachiocephalic vein aneurysm, which was surgically managed, highlighting the role of dynamic contrast-enhanced magnetic resonance imaging as a definitive diagnostic modality in this patient.

MR fistulography with percutaneous instillation of aqueous jelly: A cost effective technique innovation.

Background: Perianal fistula is a commonly encountered condition in routine surgical practice. Accurate presurgical mapping of these tracts is vital to prevent recurrence. We have assessed the effectiveness of percutaneous instillation of aqueous jelly prior to magnetic resonance (MR) fistulography.

A Comparative Study of Pituitary Volume Variations in MRI in Acute Onset of Psychiatric Conditions.

Introduction: The growing belief that endocrine abnormalities may underlie many mental conditions has led to increased use of imaging and hormonal assays in patients attending to psychiatric OPDs. People who are in an acute phase of a psychiatric disorder show Hypothalamic Pituitary Adrenal (HPA) axis hyperactivity, but the precise underlying central mechanisms are unclear.

Aim: To assess the pituitary gland volume variations in patients presenting with new onset acute psychiatric illness in comparison with age and gender matched controls by using MRI.

Imaging and interventions in idiopathic intracranial hypertension: A pictorial essay.

Intracranial hypertension is a syndrome of elevated intracranial pressure that can be primary or secondary. The primary form, now termed idiopathic intracranial hypertension (IIH), was in the past a disease of exclusion and imaging played a limited role of excluding organic causes of raised intracranial pressure. However imaging markers have been described with patients with IIH at the orbit, sella and cerebral venous system.

Orbital apex osteodural fistula--An unusual surgical access.

Dural arteriovenous fistulas (DAVFs) are fistulas connecting the branches of dural arteries to dural veins or a venous sinus. Osteodural fistulas are a rare subset of this group of diseases. We wish to report a rare case of an osteodural arteriovenous fistula at the foot of the superior ophthalmic vein (SOV), treatment of which required an unusual surgical approach via the orbit and SOV.

Pressure injectors for radiologists: A review and what is new.

Pressure Injectors are used routinely in diagnostic and interventional radiology. Advances in medical science and technology have made it is imperative for both diagnostic as well as interventional radiologists to have a thorough understanding of the various aspects of pressure injectors. Further, as many radiologists may not be fully conversant with injections into ports, central lines and PICCs, it is important to familiarize oneself with the same.

Cerebral and spinal vascular involvement in Hereditary Hemorrhagic Telengiectasia: Report of two cases.

Introduction: We present two cases of Hereditary Hemmorhagic Telengiectasia (HHT), one pediatric and the other adult, with a view to highlight the myriad cerebral and spinal vascular manifestations of this disease. The syndrome and its various findings will be reviewed including the utility of angiography in assessing the various vascular abnormalities of the cerebral and spinal vasculature.

Methods: A review of literature regarding various developmental abnormalities including brain and spinal cord arterio-venous malformations (AVMs), arterio-venous fistulae (AVFs), micro AVMs, micro-fistulae, aneurysms and cavernomas that occur in pediatric and adult population subsets of HHT.

Abdominal sonography in the medical evaluation of aviation aspirants.

Background: Ultrasonography is increasingly used in elderly individuals for screening of occult malignancy and abdominal aortic aneurysm. Its utility as a screening tool in healthy asymptomatic individuals is not yet established. The current study was undertaken to evaluate the utility of abdominal and pelvic ultrasonographic screening as an adjunct to routine physical examination among young adults undergoing initial medical examination for aviation duties.
