Item Absence of the left common carotid artery with cervical origin of the right subclavian artery(AMERICAN JOURNAL OF NEURORADIOLOGY, 2006)We report the case of a 1(1)/(2)-year-old female child, who developed symptomatic hemorrhage from major aorto-pulmonary collaterals after surgery for Tetrology of Fallot. During the course of embolization of the aorto-pulmonary collaterals, we discovered the presence of direct origin of the left internal and external carotid arteries from the aortic arch. Further, there was cervical origin of right subclavian artery. We discuss the clinical significance and potential embryological mechanism in development of this anomaly.Item Aneurysmal bone cyst of skull - A report of two cases(RIVISTA DI NEURORADIOLOGIA, 2005) Purkayastha, S; Gupta, AK; Kapilamoorthy, TR; Bodhey, NK; Thomas, BAn aneurysmal bone cyst is a benign lesion usually involving the long bones, vertebrae including odontoid, hypoid and mandible. Skull is a rare site for aneurysmal bone cyst. Only 3% occur in the cranium and sites of involvement include temporal, occipital, orbital, frontal, parietal, ethmoids and sphenoid bones in order of frequency. We report two cases of aneurysmal bone cysts in occipital bone and maxilla. We discuss the radiological features, surgical findings and emphasize the role of endovascular management in these lesions.Item Carotid artery stenting: Results and long-term follow-up(NEUROLOGY INDIA, 2006)Background and Purpose: The role of carotid artery stenting (CAS) as an alternative to carotid endarterectomy in the treatment of for symptomatic carotid artery stenosis is investigated. Materials and Methods: Forty-seven patients underwent CAS over 10-year period. Forty-nine vessels were treated. Stenosis quantification was done using North American symptomatic carotid endarterectomy trial method. The mean follow-up period by clinical and Duplex examination ranged is 5.6 years. Results: The technical success rate was 100%. There were four deaths (8.1%) and two (4.1%) minor strokes within thirty days of procedure. There was no major strokes. All patients with minor stroke achieved complete recovery at 1-month follow up. Two deaths occurred probably due to hyperperfusion syndrome (HS) and two due to cardiac arrest. Conclusion: CAS is an effective treatment modality of symptomatic carotid artery disease but should be carefully done in high-risk groups having severe medical ailments and those having severe bilateral stenosis of the carotid arteries.Item Cerebral arteriovenous malformation embolized through persistent primitive hypoglossal artery - A case report (vol 11, pg 241, 2005)(INTERVENTIONAL NEURORADIOLOGY, 2005)Carotid-vertebral anastomoses are commonly detected as incidental findings. But sometimes these channels are important for the clinical condition of the patient. Here a case of right thalamo-capsular arteriovenous malformation is described where a persistent primitive hypoglossal artery was the only route for embolization of the arteriovenous malformation.Item Coil Migration Through Skin After Posterior Tibial Artery Pseudoaneurysm Trapping(CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY, 2011) Chatterjee, S; Bodhey, NK; Gupta, AK; Bele, KItem CT angiographic demonstration of agenesis of the internal carotid artery with transsellar cavernous collateral and PCA aneurysm(RIVISTA DI NEURORADIOLOGIA, 2004) Bodhey, NK; Gupta, AK; Varma, DR; Sonwalkar, HA; Purkayastha, SWe report an unusual case of complete agenesis of the right internal carotid artery (ICA) with transsellar anastomosis from the cavernous segment of the contralateral ICA and presence of a posterior cerebral artery aneurysm and aberrant origin of the right subclavian artery.Item Delayed frontal lobe malignancy in a child treated for medulloblastoma(RIVISTA DI NEURORADIOLOGIA, 2005) Bodhey, NK; Gupta, AKA high grade astrocytoma developing following radiotherapy for a medulloblastoma is reported in a six-year-old girl. The latency period was unusually short. The stigmata of Von Recklinghausen's disease in this patient suggest a genetic propensity, though radiation for the primary tumor is considered a more likely predisposing factor in addition to the increased likelihood of development of second malignant tumor in survivors of childhood cancer.Item Duplicate origin of the right vertebral artery in a patient with stroke. Case report(RIVISTA DI NEURORADIOLOGIA, 2004) Purkayastha, S; Gupta, AK; Sonwalkar, H; Bodhey, NKItem Early sternal erosion and luetic aneurysms of thoracic aorta: report of 6 cases and analysis of cause-effect relationship(EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY, 2005)Six patients with luetic aneurysm of the ascending aorta eroding the sternum are presented. The erosion was an early and principal presentation and the site of erosion and location and morphology of aneurysm were identical in all six patients. The erosion mainly affected the right half of the manubrium and medial end of right clavicle. The aneurysms arose from the junction of the ascending and transverse arches of the thoracic aorta and had narrow opening close to the origin of the innominate artery. The identical presentation, aetiology, angiographic location and morphology, corroborated further at surgery, suggests that syphilitic aneurysms in this location have a strong tendency to cause early sternal erosion.

Bromocriptine therapy is an effective alternative to surgery in this group of patients. We report a case of prolactinoma where the patient was put on bromocriptine therapy and after 15 months of follow-up the tumor almost regressed giving an empty sella appearance.Item Embolization of choroid plexus arteriovenous malformation. A case report(RIVISTA DI NEURORADIOLOGIA, 2005) Gupta, AK; Varma, DR; Bodhey, NK; Purkayastha, SChoroid plexus arteriovenous malformations are rare lesions that usually present with intraventricular hemorrhage. Management of these lesions is challenging as their deep location makes them relatively inaccessible for surgical excision. Recent advances in microcatheter technology have made it possible to access these lesions safely for embolization. We report a case of lateral ventricular choroid plexus arteriovenous malformation completely occluded by endovascular treatment.Item Embolization of craniofacial vascular malformations(RIVISTA DI NEURORADIOLOGIA, 2005) Bodhey, NK; Gupta, AK; Purkayastha, S; Kesavadas, C; Krishnamoorthy, T; Kapilamoorthy, T; Thomas, BCraniofacial vascular malformation (CVM) is a major cosmetic concern and may present as catastrophic situations like bleeding apart from the functional impairment. The treatment of CVM has been very challenging. Till the recent past, surgery was the mainstay of treatment. However, because of the torrential intraoperative haemorrhage and frequent recurrences, embolization has evolved as a major adjunct in treating these lesions. This study evaluated the efficacy of various preoperative embolization techniques in the management of CVM. A total of 94 patients (54 males, 40 females) with an age range from three months to 68 years with a mean of 42.4 years having craniofacial AVM (forehead, face, neck and scalp lesions) were treated with the various embolization techniques: Arterial route with (a) hydrogel only (b) hydrogel and gelfoam (c) gel foam only (d) nbutyl cyanoacrylate (NBCA), Venous route and direct puncture injection of NBCA. The devascularisation achieved with the transarterial route was between 80-95% with particulate agents and 95-100% with NBCA. Direct puncture embolization also resulted in near total devascularisation of the lesion. This resulted in a significant decrease in blood loss at surgery. Cure was obtained in a few patients without the need for surgery. After embolization, almost all the patients had mild pain and subtle increase in the swelling with firmer consistency. The embolization of CVM is an essential adjunct to surgery in most cases and can be curative in a few patients. Hydrogel, PVA and gelfoam are good embolizing agents with NBCA being excellent when used with direct puncture.Item Endovascular treatment of ruptured intracranial aneurysms: Immediate result and long term follow up - An Indian experience(JOURNAL OF NEURORADIOLOGY, 2006) Gupta, AK; Purkayastha, S; Bhattacharya, RN; Bodhey, NKItem Endovascular treatment of ruptured posterior circulation dissecting aneurysms(JOURNAL OF NEURORADIOLOGY, 2006) Purkayastha, S; Gupta, K; Krishnamoorthy, AT; Bodhey, NKBackground and aim: Dissecting aneurysms of the posterior circulation constitute a relatively uncommon subgroup of aneurysms. They account for 3-7% of cases of nontraumatic subarachnoid hemorrhage. Because of high risk, in most cases the patients require surgical or endovascular therapy. In this study we discuss the clinical efficacy of endovascular treatment with long-term follow-up in ruptured dissecting aneurysms of the posterior circulation. Materials and methods: This retrospective study was conducted at our institution between January 1995 and June 2005. Eight patients (4 male; 4 females) ranging in age from 24 to 65 years (mean, 46.75 years), were included. All presented with SAH. Endovascular treatment was based on the configuration of the dissecting aneurysm. Attempt was made to occlude the dissecting aneurysm. Result: A total of 8 ruptured dissecting aneurysms in the posterior circulation were treated. Out of them 5 were in the intradural vertebral artery, 2 in the basilar trunk and one in the proximal PCA. All the cases were technically successful. We have seen only two complications. The pre and post procedure (at the time of discharge) mean modified Rankin scores in the patients were 4.6 (SD 0.51) and 1.7 (SD 1.98). This improvement in Rankin score after endovascular treatment was statistically significant (Wilcoxon signed rank test, P=.017). Conclusion: Endovascular management of these lesions is safe and effective mode of treatment and gives adequate protection from rebleed.Item Evaluation, management, and long-term follow up of vein of Galen malformations(JOURNAL OF NEUROSURGERY, 2006) Gupta, AK; Rao, VRK; Varma, DR; Kapilamoorthy, TR; Kesavadas, C; Krishnamoorthy, T; Thomas, B; Bodhey, NK; Purkayastha, SObject. Vein of Galen malformations (VGMs) are extremely rare intracranial lesions. Clinical presentation and management strategies vary significantly in different areas of the world. The authors report their experience in evaluation, management, and long-term follow up of these lesions in India. Methods. Between October 1983 and June 2003, 25 patients with VGMs were referred to the authors' institution for evaluation and management. Ten children younger than 2 years of age presented with rapidly increasing head size as the chief complaint. Among 11 children 2 years of age or older, the most common presenting symptom was chronic headache. Four patients who presented during adulthood had chronic headache for many years before presentation. Angiographic evaluation of the lesion was performed in 21 patients. Fifteen patients were treated using endovascular techniques. Injection of the embolic material was performed after induction of systemic hypotension when the flow in the fistula was high. Complete occlusion of the arteriovenous shunt could be achieved in two patients with vein of Galen aneurysmal dilation (100% of patients with this type of malformation) and in five of the six patients with the mural type of malformation (83%). Among patients with the choroidal type of malformation, complete obliteration of the shunt could be achieved in three patients. In three patients with high-flow choroidal malformations, embolization carried out in a single sitting resulted in shunt reduction of nearly 90%. These patients received clinical follow up. Conclusions. The authors' experience in evaluation and management of VGMs reveals that in areas of the world where access to dedicated specialist care is limited, the clinical presentation of VGMs can differ appreciably from the classic descriptions in the literature. Endovascular management of these lesions results in excellent angiographic and clinical results.Item Metachronous malignant fibrous histiocytoma of skull - A case report(RIVISTA DI NEURORADIOLOGIA, 2005) Pendharkar, HS; Bodhey, NK; Gupta, AK; Purkayastha, S; Sandhyamani, S; Burathoki, SKPrimary Malignant Fibrous Histiocytoma (MFH) of skull is a rare tumour with malignant features similar to MFH located elsewhere. Primary MFH of bone may metastasize to soft tissues or other bones. We report a case of a metachronous MFH involving the skull.Item MRI features of tubercular spinal arachnoiditis - A case report(RIVISTA DI NEURORADIOLOGIA, 2005) Purkayastha, S; Bodhey, NK; Gupta, AK; Kesavadas, CRecently, there has been a significant rise in the prevalence of tuberculosis and an increase in the extrapulmonary manifestations worldwide. Diagnosis of extrapulmonary tuberculosis is often difficult. Although a positive chest radiograph or positive tuberculin skin test supports the diagnosis, negative results do not exclude the possibility of extrapulmonary tuberculosis. However, recognition and understanding of the common and uncommon radiologic findings of extrapulmonary tuberculosis can help in diagnosis. Here we describe the value of MRI in demonstration of subtle meningeal pathology in spinal arachnoiditis.Item Neurofibromatosis type I with occipital encephalocele(NEUROLOGY INDIA, 2006) Bodhey, NK; Gupta, AKItem Neuroimaging in leptomeningeal carcinomatosis: the importance of gadolinium-enhanced MRI(RIVISTA DI NEURORADIOLOGIA, 2005) Bodhey, NK; Purkayastha, S; Gupta, AKCNS parenchymal metastases are common as is metastatic meningeal involvement. However, the high index of suspicion and contrast enhanced MRI also help in detecting meningeal deposits. We herewith report cases of leptomeningeal deposits in patients with a known primary tumour elsewhere. The importance of gadolinium enhanced MRI is stressed.
