    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.

    Bilateral cerebral venous angioma associated with varices: A case report and review of the literature
    (AMERICAN JOURNAL OF NEURORADIOLOGY, 2005) Vattoth, S; Purkayastha, S; Er, J; Gupta, AK
    A varix occurring with a cerebral venous angioma is a rare combination of cerebral vascular malformations. The most common vascular anomaly associated with a venous angioma is a cavernous angioma. We report a case of bilateral supratentorial venous angioma with 2 varices involving the angioma situated on the right frontotemporal region. Multiple subependymal veins were seen in the right supratentorial region, which joined to form multiple collector veins, which, in turn, unified into a tortuous channel in the region of the sylvian fissure and continued into venous varices.

    CT cisternography of paradoxical cerebrospinal fluid rhinorrhea after operation for acoustic neuroma
    (RIVISTA DI NEURORADIOLOGIA, 2005) Thomas, B; Purkayastha, S; Vattoth, S; Gupta, AK
    Cerebrospinal fluid (CSF) rhinorrhea after acoustic neuroma surgery is a well-known complication. CT cisternography can be used to demonstrate the entry of CSF from cerebellopontine angle cistern into the mastoid air cells, middle ear and then into nasopharynx via Eustachian tube. We report a case of paradoxical CSF rhinorrhea after surgery for acoustic neuroma in which the path of CSF leak was accurately demonstrated using CT cisternography.

    Cutting balloon angioplasty in type 1 aortoarteritis - A case report
    (RIVISTA DI NEURORADIOLOGIA, 2004)
    Percutaneous transluminal angioplasty (PTA) of steno-occlusive lesions in the supra-aortic arch vessels in aortoarteritis is associated with suboptimal results and higher restenosis rates, particularly in those with diffuse disease. We report a patient with aortoarteritis who presented with critical stenosis of the right common carotid artery, right subclavian artery and 50 percent stenosis of the brachiocephalic artery. Left common carotid and left subclavian arteries were occluded and were reforming via collaterals. Cutting balloon PTA of right subclavian, right common carotid and brachiocephalic arteries was done with good anatomic patency and clinical results on six month follow up.

    Hyperperfusion syndrome after supraaortic vessel interventions and bypass surgery
    (JOURNAL OF NEURORADIOLOGY, 2005)
    Cerebral hyperperfusion and hemorrhage is a recognized complication of endarterectomy, aortocarotid bypass surgery or angioplasty and stenting of the carotid or vertebral artery. We performed 87 balloon angioplasty, stenting and bypass surgery of arteries supplying the brain over the last 15 years. We have found 6 cases of hyperperfusion syndrome in a total of 87 procedures. So the incidence of hyperperfusion was noted as 6.89%. Two cases occurred after two combined procedures in a single sitting. Hyperperfusion syndrome is a well-known complication of craniocervical revascularisation procedures. gut with proper care, including strict post procedural control of blood pressure and staged procedure in case of multiples vessel stenosis, these complications can be largely avoided.
