A previously well 27-year-old woman presents with a history of transient ischaemic attack affecting her right side and speech. She had returned to the United Kingdom from a holiday in New Zealand two days previously. On examination there was nothing abnormal to find. An ECG, chest X-ray, CT brain scan and routine haematology and Biochemistry were all normal. What is the most likely underlying abnormality?
1) atrial myxoma
2) carotid artery stenosis
3) embolus from paroxysmal atrial fibrillation
4) patent foramen ovale
5) subarachnoid haemorrhage
Explain Ur Answers PLZ

foramen ovale.
long fly. venous stasis. thrombus in veins --> should go to lungs and dissolve, but no luck - foramen ovale is there --> thrombus goes to aorta and than embolize brain.
by the way, what organ is less likely to be embolized in such a situation?

This is a typical cause of stroke in a young person due to prolonged immobility. Deep vein thrombosis with patent foramen ovale will cause paradoxical embolism and stroke.
