Symptomless disease!

I desire to write about one devastating pathogenesis of major artery of human – carotid artery stenosis. I use to mention this stenosis carotid artery as carotid artery disease (CAD). The most devastating feature relating with clinical symptom is that this carotid artery stenosis sometime reveals symptomless, which is harmful for developing cerebral ischaemia. If we consider about medical problems that persuading carotid artery stenosis, cardiac disease (CD) or hypertension (HTN) are mentioned. Therefore, in regular medical check up of CD or HTN, it is wise to arrange one bed side examination of carotid arteries using US imaging method (ultrasound imaging).
