Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

Core Features

Gasperini syndrome (GS), a rare brainstem syndrome, is featured by ipsilateral cranial nerves (CN) V–VIII dysfunction with contralateral hemibody hypoesthesia. While there have been 18 reported cases, the GS definition remains ambiguous. We report a new case and reviewed the clinical features of this syndrome from all published reports to propose a new definition. A 57-year-old man with acute brainstem stroke had right CN V–VIII and XII palsies, left body hypoesthesia and ataxia. Brain MRI showed an acute stroke in the right caudal pons and bilateral cerebellum. After a systematic review, we classified the clinical manifestations into core and associate features based on the frequencies of occurring neurological deficits. We propose that a definitive GS requires the presence of ipsilateral CN VI and VII palsies, plus one or more of the other three core features (ipsilateral CN V, VIII palsies and contralateral hemibody hemihypalgesia). Additionally, GS, similar to Wallenberg’s syndrome, represents a spectrum that can have other associated neurological features. The revised definition presented in this study may enlighten physicians with the immediate recognition of the syndrome and help improve clinical localization of the lesions and its management.

Moyamoya disease is a chronic progressive cerebrovascular disease characterized by bilateral occlusion or stenosis of arteries around circle of Willis. We report a case of 18-year-old female presented with recurrent episodes of headache and vertigo. On cerebral angiography, the patient was diagnosed to have moyamoya disease. On further evaluation, thrombophilia profile showed increased homocysteine level. The patient was treated conservatively with cobalamin and aspirin and advised for revascularization. According to the literature, there are few case reports of moyamoya disease with thrombotic disorders. Hence, we are reporting this interesting and rare case.

Thomas Willis was born four hundred years ago on 27 January 1621 in Wiltshire. He has been dubbed ‘the father of neurology’ and is remembered for the Circle of Willis at the base of the brain. Young Thomas was educated at Oxford as a schoolboy and undergraduate. From 1646 he practised medicine and studied chemistry; he joined the Oxford Experimental Philosophical Club, and was Sedleian Professor of Natural Philosophy from 1660. He established a prosperous medical practice at The Angel on Oxford High Street, and achieved international acclaim for Cerebri anatome (1664). Lured to London in 1667, Willis lived in style but attended the sick poor on Sundays and worshipped twice daily at St Martin-in-the-Fields.
