Minor Stroke

The purpose of this study was to evaluate the efficacy and safety of staged carotid stenting (CS) and carotid endarterectomy (CEA) for bilateral internal carotid artery stenosis. With this strategy, initial carotid stenting was performed for the high grade carotid stenosis to reduce the risk of subsequent CEA. Eight patients were treated with staged CS and CEA; CS for asymptomatic side followed by CEA for symptomatic side. Sufficient revascularization was obtained in all procedures but one CS procedure. Two minor stroke caused by distal embolism occurred during the perioperative period of CS. Postprocedural persistent hypotension was observed in one CS procedure. The mean interval between CS and CEA was 19.8 days. In conclusion, although our strategy has some advantages such as avoidance of bilateral cranial nerve palsy and shorter admission period over staged CEA, relatively high complication rate was noted at the first CS without any stroke morbidity post CEA. Our preliminary result showed that further reduction of periprocedural complication rate at the initial stenting is mandatory for this approach justified.

Artery Flow

Abstract OBJECTIVE We evaluated the effect of carotid endarterectomy on chronic ocular ischemic syndrome due to internal carotid artery stenosis by use of data obtained from ophthalmic artery color Doppler flow imaging. METHODS We examined 11 patients with ocular ischemic syndrome due to internal carotid artery stenosis (>70% stenosis) who were being treated by carotid endarterectomy. Ophthalmic artery color Doppler flow imaging indicated ophthalmic artery flow direction and peak systolic flow velocity and was performed before and at 1 week, 1 month, and 3 months after surgery. RESULTS We assessed the ophthalmic arteries of 11 patients via color Doppler flow imaging. Before undergoing carotid endarterectomy, five patients showed reversed ophthalmic artery flow. In the other six patients who experienced antegrade ophthalmic artery flow, the average peak systolic flow velocity was 0.09 ± 0.05 m/s (mean ± standard deviation). Preoperative reversed flow resolved in each patient 1 week after undergoing surgery. All patients showed antegrade ophthalmic artery flow. The average peak systolic flow velocity in the patients who had preoperative antegrade flow rose significantly, to 0.21 ± 0.14 m/s (P < 0.05). There was no significant change as compared with findings at 1 week after surgery. During the follow-up period (mean, 32.4 mo), no patients complained of recurrent visual symptoms. At the end of the study period, visual acuity had improved in five patients and had not worsened in the other six patients. CONCLUSION Carotid endarterectomy was effective for improving or preventing the progress of chronic ocular ischemia caused by internal carotid artery stenosis.

Angioplasty And Stenting

Abstract Carotid artery stenosis is implicated in up to 40% of all ischemic strokes. Accordingly, symptomatic, high-grade carotid artery stenosis portends an especially high risk of future stroke. Intervention via open or endovascular approaches drastically reduces this risk. Under the appropriate conditions, carotid artery stenting serves as a safe and effective alternative to carotid endarterectomy. We present the case of a 57-yr-old male with symptomatic, high-grade stenosis of his right internal carotid artery, for whom a history of radiation to the head and neck represented a relative contraindication to carotid endarterectomy, and thus endovascular treatment with angioplasty and stenting was performed. Informed consent was obtained prior to the procedure. Intraprocedurally, stent delivery past the area of stenosis proved somewhat challenging. However, by employing several nuanced maneuvers, we utilized our guiding catheter in a nonconventional manner in order to successfully perform the procedure. As the field of neuroendovascular surgery evolves, each case provides us unique lessons, which in turn expands our interventional capabilities and adds to the armamentarium of neuroendovascular techniques. We present this surgical video both as a means to provide a general overview of carotid artery stenting, and to share a lesson learned through the implementation of an interesting technical nuance.
