BACKGROUND To study the effect of timing of total enteral feeding on various nutritional parameters and neurological outcome in patients with severe traumatic brain injury (TBI). METHODS One hundred and fourteen patients, in the age group of 20-60 years, admitted within 24 h of TBI with Glasgow Coma Scale (GCS) 4-8 were enrolled for the study. Nineteen(More)
BACKGROUND Spinal dural arteriovenous fistula (SDAVF) is a common type of spinal vascular lesion. However, there has not been any published study on its clinico-radiological characteristics or surgical outcome from India. AIM The aim of this study was to determine the clinico-radiological features of patients with SDAVF, outcomes following surgical(More)
BACKGROUND Large highly vascular meningiomas surgically challenging when preoperative embolization is not feasible. CASE DESCRIPTION We present an illustrative case of 'en bloc' excision of a highly vascular giant lateral sphenoid wing meningioma using the technique of 4 D's. After ruling out neurovascular encasement and significant brain interposition,(More)
OBJECTIVE To study the visual outcome after surgery for pituitary adenomas with visual deficits. MATERIALS AND METHODS All patients with pituitary adenoma, who presented from 2003-2014 in a tertiary care institute, were included in the study. Surgical outcome was measured in terms of difference in visual acuity, visual fields and optic fundus parameters(More)
Azygos distal anterior cerebral artery (Az.DACA) is a rare anatomical variant. This variant has been found to be associated with aneurysms in a significant proportion of patients. We present two cases of Az.DACA aneurysms associated with this anatomical variant with different branching patterns and the corresponding technical difficulties in clipping such(More)
BACKGROUND Hemangioblastoma (HBL) is rare in the cerebellopontine angle (CPA) with questionable origin and limited access for circumferential dissection and "en-bloc" excision. We report a case of surgical removal of large solid CPA-HBL and discuss the pattern of blood supply suggesting its origin and indicating preoperative embolization. CASE DESCRIPTION(More)
OBJECTIVE Regrowth of the lesion after surgical removal of pituitary adenomas is uncommon unless subtotal resection was originally achieved in the first surgery. Treatment for recurrent tumor can involve surgery or radiotherapy. Locations of residual tumor may vary based on the original approach. The authors evaluated the specific sites of residual or(More)
