    Adult onset moyamoya disease: Institutional experience
    (NEUROLOGY INDIA, 2011) Chinchure, SD; Pendharkar, HS; Gupta, AK; Bodhey, N; Harsha, KJ
    Moyamoya disease is a progressive steno-occlusive disease of bilateral carotid forks with the formation of fine collateral vascular network and is an angiographic diagnosis. We analyzed case records of 11 patients with "adult-onset moyamoya disease." Six patients presented with intracranial hemorrhage (intracerebral and/or intraventricular) and 5 with focal ischemia. Angiography revealed bilateral Internal carotid artery involvement in 8 patients and unilateral involvement in 3. Posterior cerebral artery involvement was seen in 3 patients. Saccular aneurysm involving posterior circulation was seen in only 1 patient. Although rare, adult-onset moyamoya disease should be considered as one of the causes for intracerebral and intraventricular hemorrhage in adults.

    Anomalous Origins of Bilateral Vertebral Arteries in a Child with Down Syndrome and Moyamoya Disease A Case Report
    (INTERVENTIONAL NEURORADIOLOGY, 2012) Mishra, A; Pendharkar, H; Jayadaevan, ER; Bodhey, N
    Variations in vertebral artery origin and course are well-described in the literature. The origin of right vertebral artery from the right common carotid artery is an extremely rare variant. We describe a unique case of a child with Down syndrome with variant origins of bilateral vertebral artery, an aberrant right subclavian artery and concomitant Moyamoya disease of intracranial circulation. The presence of variations of the origin and course of craniocervical arteries might have profound implications in angiographic and surgical procedures and hence it is of great importance to be aware of such a possibility.

    Cerebral myxomatous angiopathy. Imaging features
    (RIVISTA DI NEURORADIOLOGIA, 2004) Sonwalkar, HA; Gupta, AK; Varma, DR; Purkayastha, S; Bodhey, N; Kesavadas, C
    Strokes due to embolization from a cardiac myxoma are rare. Myxomatous cerebral emboli can cause occlusion of intracranial vessels or oncotic aneurysm formation. We describe a case of cardiac myxoma presenting with stroke having bilateral cerebral infarct and oncotic aneurysm formation. Myxomatous emboli have characteristic CT, MR and angiography findings, which are well seen in this case. The pathogenesis, imaging features, clinical presentation and natural history are discussed.

    Perioperative implications of retrograde flow in both the subclavian arteries in an adult undergoing surgical repair of coarctation of aorta
    (INTERACTIVE CARDIOVASCULAR AND THORACIC SURGERY, 2011) Neema, PK; Manikandan, S; Bodhey, N; Gupta, AK
    During surgical repair of coarctation of aorta (CoA), management of spinal cord ischemia and prevention of paraplegia is an important issue. The risk factors for paraplegia include level and duration of aortic-clamping, clamping of left subclavian artery (SCA), intraoperative temperature, variability of collateral circulation to the spinal cord, cerebrospinal fluid pressure, upper body arterial pressure, and aortic pressure beyond the aortic clamp. A short clamp time (<30 min), and distal aortic pressure >60 mmHg, minimizes the risks of spinal cord injury. In an adult patient during surgical repair of CoA, the arterial pressure in the femoral artery remained around 45 mmHg and repair took 83 min of aortic-clamping. Neurological assessment on regaining consciousness showed no deficit of lower limbs. Aortic root angiogram had shown retrograde filling of both SCAs. A unique situation in which clamping of SCAs would increase flow to the spinal cord as their clamping would stop stealing of blood and aortic-clamping proximal to CoA will further increase collateral flow; because of these reasons, the patient tolerated prolonged aortic-clamping despite low distal aortic pressure without neurological deficit. However, aortic-clamping increased left ventricular after-load and the patient developed worsening of mitral regurgitation and pulmonary hypertension during aortic clamping.
