  • External Carotid Artery stenting to treat patients with symptomatic ipsilateral internal Carotid Artery occlusion a multicenter case series
    2010
    Co-Authors: Todd A Abruzzo, Ziad A Hage, Felipe C Albuquerque, Guilherme Dabus, Mark K Eskandari, Lee R Guterman, Michael C Hurley, Ricardo A Hanel, Elad I Levy, Christopher Nichols
    Abstract:

    Background The External Carotid Artery (ECA) anastomoses in many distal territories supplied by the internal Carotid Artery (ICA) and is an important source of collateral circulation to the brain. Stenosis of the ECA in ipsilateral ICA occlusion can produce ischemic sequelae. Objective To examine the effectiveness of ECA stenting in treating symptomatic ipsilateral ICA occlusion. Methods We retrospectively reviewed patient databases from 5 academic medical centers to identify all individuals who underwent ECA stenting after 1998. For all discovered cases, coinvestigators used a common submission form to harvest relevant demographic information, clinical data, procedural details, and follow-up results for further analysis. Results Twelve patients (median age, 66 years; range, 45-79 years) were identified for our cohort. Vessel disease involvement included severe ECA stenosis >or= 70% in 11 patients and ipsilateral ICA occlusion in all patients. Presenting symptoms included signs of transient ischemic attack, stroke, and amaurosis fugax. ECA stenting was associated with preservation of neurological status in 11 patients and resolution of symptoms in 5 patients at a median follow-up time of 26 months (range, 1-87 months; mean, 29 months). Symptomatic in-stent restenosis did not occur within any patient during the follow-up course. Conclusion We found ECA stenting in symptomatic ipsilateral ICA disease to be a potentially effective strategy to preserve neurological function and to relieve ischemic symptoms. Further investigation with larger studies and longer follow-up periods is warranted to elucidate the true indications of this management strategy.

  • External Carotid Artery angioplasty and stenting to augment cerebral perfusion in the setting of subacute symptomatic ipsilateral internal Carotid Artery occlusion case report
    2007
    Co-Authors: Joseph G Adel, Bernard R Bendok, Ziad A Hage, Andrew M Naidech, Jeffery W Miller, Hunt H Batjer
    Abstract:

    The authors performed External Carotid Artery (ECA) angioplasty and stenting in a 45-year-old man who had presented with right hemispheric crescendo ischemic symptoms stemming from acute right internal Carotid Artery occlusion (ICAO). This unique application of ECA angioplasty and stenting augmented cerebral perfusion and improved clinical symptoms. In certain situations, ECA stenting can increase cerebral perfusion in the setting of ICAO and ECA stenosis. The authors are the first to describe this approach in this context.

  • spontaneous bilateral internal Carotid and vertebral Artery dissections with dominant hemisphere circulation maintained by External Carotid Artery ophthalmic Artery anastomoses
    2019
    Co-Authors: Danielle Golub, Siddhant Dogra, Jose Torres, Maksim Shapiro
    Abstract:

    Spontaneous cervical Artery dissection (sCAD) is a major cause of stroke in young adults. Multiple sCAD is a rarer, more poorly understood presentation of sCAD that has been increasingly attributed to cervical trauma such as spinal manipulation or genetic polymorphisms in extracellular matrix components. The authors present the case of a 49-year-old, otherwise healthy woman, who over the course of 2 weeks developed progressive, hemodynamically significant, bilateral internal Carotid Artery and vertebral Artery dissections. Collateral response involved extensive External Carotid Artery-internal Carotid Artery anastomoses via the ophthalmic Artery, which were instrumental in maintaining perfusion because circle of Willis and leptomeningeal anastomotic responses were hampered by the dissection burden in the corresponding collateral vessels. Endovascular intervention by placement of Pipeline embolization devices and Atlas stents in bilateral internal Carotid arteries was successfully performed. No syndromic or systemic etiology was discovered during a thorough workup.
