Common medical ethics dilemmas: Few reflections from a Saudi perspective.

Medical ethics plays a crucial role in physicians' daily practice, as it reflects on themselves, their institution, and, most importantly, the outcome of the treatment they provide to their patients. Common medical ethics dilemmas faced in Saudi Arabia include: end-of-life care, patient rights, which comprise autonomy, informed consent, and confidentiality, reproductive ethics, and equity of resources. The identification of flaws within the healthcare system and the implementation of clear guidelines are important to overcome the risk of malpractice and flawed judgment, and ensure the delivery of the best possible care to patients.

Management of Free-Floating Thrombus in the Vertebral Artery in a Middle-Aged Smoker with Secondary Polycythemia Vera.

Free-floating thrombus (FFT) of the cervicocranial arteries is a rare neurovascular condition. Up to now, there is no standardized definition for FFT. Therefore, FFT is occasionally mistaken for intraluminal thrombus (ILT) or smooth mural thrombus. The most precise and ideal definition of FFT would be a long-extended intraarterial thrombus that is attached to the arterial wall with its one end, while its other end is surrounded by blood flow and moves freely with the cardiac cycle. FFT usually manifests as an ischemic stroke, thus it is considered as an emergency case. Herein, we report a rare case of symptomatic FFT in the left vertebral artery extending from V0 to V2 segments in a middle-aged smoker, who presented with multiple embolic strokes in different territories of posterior circulation and was successfully treated medically. This case sheds light on the challenges of the clinical approach of FFT in the vertebral artery and it is an attempt to draw attention to the necessity of conducting a large-scale study to find out the ideal approach to manage such conditions.
