Low carotid stump pressure as a predictor for ischemic symptoms and as a marker for compromised cerebral reserve in octogenarians undergoing carotid endarterectomy
Carotid artery occlusive disease can cause stroke by embolization, thrombosis, and hypoperfusion. The majority of strokes secondary to cervical carotid atherosclerosis are believed to be of embolic etiology. However, cerebral hypoperfusion could be an important factor in perioperative stroke. We retrospectively reviewed the stump pressure (SP) of carotid endarterectomy (CEA) of patients at Pennsylvania Hospital to identify whether physiologic perfusion differences account for differences in perioperative stroke rates, particularly in octogenarians.

Emergent intracranial surgical embolectomy in conjunction with carotid endarterectomy for acute internal carotid artery terminus embolic occlusion and tandem occlusion of the cervical carotid artery due to plaque rupture.
Abstract Acute internal carotid artery (ICA) terminus occlusion is associated with extremely poor functional outcomes or mortality, especially when it is caused by plaque rupture of the cervical ICA with engrafted thrombus that elongates and extends into the ICA terminus. The goal of this study was to evaluate the efficacy and safety of surgical embolectomy in conjunction with carotid endarterectomy (CEA) for acute ICA terminus occlusion associated with cervical plaque rupture resulting in tandem occlusion. A retrospective review of medical records was performed. Clinical and radiographic characteristics were eval...
