Is a pulmonary right-to-left shunt in patients with hereditary hemorrhagic telangiectasia associated with an increased prevalence of migraine?
This study showed a higher prevalence of PAVM in patients with migraine and HHT. The right-to-left shunt due to the PAVM might play a causal role in the pathogenesis of migraine in patients with HHT. This needs to be determined in further studies.
Obesity is an independent risk factor for death and cardiac complications after carotid endarterectomy. Surgeons should consider this when evaluating the risks and benefits of carotid endarterectomy in obese patients. Carotid artery stenting was not assessed, and future studies are needed to examine its role in management of obese patients.
