Cortical Hand Knob Paradoxical Thromboembolic Stroke in an Adolescent with Secundum Atrial Septal Defect and Paget-Schroetter Syndrome.

ABSTRACT

Venous thoracic outlet syndrome (vTOS) is an increasingly recognized diagnosis in young patients in which the subclavian vein is compressed within the costoclavicular space. With repetitive compression, thrombosis can develop and has been referred to as "effort thrombosis" or the Paget-Schroetter syndrome. Here, we present a 16-year-old boy with vTOS who presented with acute ischemic stroke (AIS) in the hand knob region of precentral gyrus due to paradoxical embolus in the setting of atrial septal defect.
