Cerebral ischaemic stroke due to paradoxical embolism

Description

This is a sudden loss of brain function due to a lack of adequate blood flow. It is the result of a thromboembolism – a blood clot that detached and travelled through the blood vessels – that originated in the venous system. Because of a heart defect, it passes through to the systemic circulation system, instead of becoming lodged in the lungs.

Coding note

If an additional code is used for anatomy, the artery affected by the stroke should be selected.
