Reversible Cerebral Vasoconstriction Syndrome: A Retrospective study from South India.

Background And Objectives: Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cause of stroke characterized by headache, seizures, focal deficits, or encephalopathy. Very little is known about this rare condition from the Indian subcontinent. Here, we present the clinical and imaging characteristics and short-term outcomes of RCVS patients from South India.

Reverse Flow Thromboembolism From Distal Subclavian Artery Aneurysm Due to Arterial Thoracic Outlet Syndrome and Posterior Circulation Stroke-Role of Dynamic Doppler Imaging.

Introduction: Arterial thoracic outlet syndrome (aTOS) is the least common among the 3 subtypes of thoracic outlet syndrome and can be the cause of posterior circulation infarction due to thrombus from a secondary thrombosed subclavian-axillary artery aneurysm.

Case Report: Here, we report a case of a 51-year-old man who presented to our institute with sudden onset vertigo, dizziness, vomiting, gait imbalance, and visual field defects immediately after strenuous exercise. Computed tomography angiography revealed bilateral cervical ribs with aneurysmal dilatation of the left distal subclavian and proximal axillary arteries.
