An independent 98 year-old man was admitted to our hospital for symptoms of progressive weakness with disorientation and dysphasia. Carotid Duplex ultrasonography was performed which revealed a totally occluded right internal carotid artery and high grade stenosis of the left internal carotid artery by velocities of 608/240 cm/sec. The patient refused surgical endarterectomy and thus he was referred for carotid artery stenting. Using the femoral artery approach and multiple catheter techniques, access to the common carotid artery could not be accomplished safely. The procedure was aborted and he was therefore brought back to the catheterization laboratory the following day for direct carotid access. Carotid artery stenting was accomplished by using of a 6F sheath percutaneously in the left common carotid, cerebral protection device (CPD) and a Nitinol stent. The patient was discharged the following day without complications. At 14 months follow-up the patient is functional and independent without recurrence of symptoms. Carotid artery stenting via direct access can be accomplished in patients when the femoral artery approach is anatomically prohibitive. In this case of advanced age and the patient’s refusal for surgery, direct carotid access was his only option.展开更多

This systemic precipitants that promote aggressive atherogenesis have been confirmed in multiple studies showing a relationship between atherosclerotic disease in one vascular bed with disease in another. However, the strength of this relationship varies from patient to patient. Thus, the practical utility of the diffuse nature of atheresclerosis is questionable. Ge and colleagues have proposed the use of left main (LM)coronary artery disease as a potential marker for left anterior descending (lAD) atherosclerotic disease. At first thought, this seems useless since the evaluation of the LM (by angiography or IVUS) can just as easily be performed in the LAD so why bother searching for such a surrogate? However, newer (non-invasive) imaging modalifies are making great gains and will be able to reliably image the LM sooner than the LAD (especially the distal LAD) so such a surrogate could have practical applications.展开更多
