Purpose: The present study aimed to explore the predictive ability of an ultrasound linear regression equation in patients undergoing endovascular stent placement (ESP) to treat carotid artery stenosis-induced ischemic stroke.Methods: Pearson's correlation coefficient of actual improvement rate (IR) and 10 preoperative ultrasound indices in the carotid arteries of 64 patients who underwent ESP were retrospectively analyzed. A predictive ultrasound model for the fitted IR after ESP was established.Results: Of the 10 preoperative ultrasound indices, peak systolic velocity (PSV) at stenosis was strongly correlated with postoperative actual IR (r = 0.622; P < 0.01). The unstable plaque index (UPI; r = 0.447), peak eccentricity ratio (r = 0.431), and plaque stiffness index (β; r = 0.512) moderately correlated with actual IR (P < 0.01). Furthermore, the resistance index (r = 0.325) and the dilation coefficient (r = 0.311) weakly correlated with actual IR (P < 0.05). There was no significant correlation between actual IR and the number of unstable plaques, area narrowing, pulsatility index, and compliance coefficient. In combination, morphological, hemodynamic, and physiological ultrasound indices can predict 62.39% of neurological deficits after ESP: fitted IR = 0.9816 – 0.1293β + 0.0504UPI – 0.1137PSV.Conclusion: Certain carotid ultrasound indices correlate with ESP outcomes. The multi-index predictive model can be used to evaluate the effects of ESP before surgery.

We describe a case of endo-luminal stent placement with Snare-assist for a cervical internal carotid artery stenosis in which percutaneous access was obtained via the brachial artery. A 68-year-old man with known disease of the carotid, peripheral, and coronary arteries, with Human T-cell Lymphotrophic Virus type-1 (HTLV-1) Associated Myelopathy (HAM) presented for endoluminal revascularization of a severe, progressive right internal carotid artery stenosis, but with aorto-iliac occlusion. Transfemoral access was complicated by an aorto-iliac occlusion. A trans-brachial approach was successfully attempted, and a SMARTer stent (Cordis Endovascular, Miami Lakes, FL) was successfully placed through a 7-French Shuttle-SL guide sheath (Cook, Bloomington) under Snare-assist. The trans-brachial approach is becoming an increasingly viable alternative route for stent placement in patients with contra-indicated or complicated femoral access routes. As devices become increasingly more pliable and smaller, the trans-brachial route will be used with increasing frequency in the select patient population for stenting of both the cervical and intracranial circulation.

Objective: Carotid artery stenosis is an important etiological cause of cerebrovascular events and stent implantation is widely used as an alternative treatment to endarterectomy. In this study, we compared the mid and late-term results of carotid artery stenosis patients who underwent endarterectomy and stent implantation. Methods: Patients who underwent endarterectomy (Group A, n: 27) and endovascular stent implantation (Group B, n: 22) due to carotid artery stenosis between 2008 and 2014 were included in the study. All examination, laboratory data and radiological images were collected from the hospital database. Morbidity and mortality developed in the mid (1-12 months) and late term (>12 months) periods were evaluated retrospectively. Results: While there were no neurological complications and restenosis in the midterm in Group A, 2 patients (9.09%) had stroke and 2 patients (9.09%) had restenosis in Group B. In the late-term, while there were no neurological complications in Group A, stroke in 3 patients (13.63%) (p=0.048) in Group B, restenosis was observed in 1 patient in Group A and 5 patients in Group B (3.7% vs 22.72%, p=0.043). Conclusion: We recommend endarterectomy as the primary approach for carotid artery revascularization and percutaneous approach especially in high-risk patients with recurrent ICA stenosis and distal carotid artery lesions.

Abstract Objective: To explore the mid-and long-term clinical efficacy analysis of carotid artery stenosis treated with carotid endarterectomy.Methods: Retrospective analysis of 89 cases of patients with carotid artery stenosisundergoing carotid endarterectomy from our center from Jan,2013 to June,2017. To gather the hospitalization data of patients including the general information, the past medical history, preoperative conditions, the situation during surgery, postoperative situations. All the patients were followed up from 16 months to 63 months, and to make survival analysis on the follow-up status.Results：Among the 89 cases, 22cases of mild stenosis ,67cases of severe stenosis. 5 cases had postoperation wound hemorrhage or hematoma, 2 cases of cranial nerve injury, 2cases of cerebral stroke. Among the 62 cases of symptomatic carotid artery stenosis,48cases have been improved in term of their clinical symptoms with improvement rate of 77.4%. The Nonparametric test of mRS scores before and after surgery showed that there was significant difference in the preoperative and postoperative scores（P<0.05）.Conclusion: The mid-and long-term clinical efficacy of carotid artery stenosis treated with carotid endarterectomy is good. The previous history of coronary heart disease and peripheral vascular diseases are the influence factors for the mid- and long-term adverse outcomes after carotid endarterectomy.

Background: Vasa vasorum neovascularization (VVN) is one of the characteristics of vulnerable plaque. The purpose of this study was to assess VVN using optical frequency domain imaging (OFDI) between symptomatic and asymptomatic carotid artery plaques, and to know its association with progression of stenosis. Methods: The carotid artery plaques were examined before angioplasty using OFDI system (LUNAWAVE TM , Terumo). VVN was defined as a no-signal tubuloluminal structures recognized on at least 3 consecutive images. A total number of VVN was compared between symptomatic and asymptomatic plaques. The stenosis was evaluated by carotid duplex scan within one year. The lesion was diagnosed as ‘progressive’ when the stenotic degree and peak systolic velocity were increased. Results: A total of 60 patients (29 symptomatic, 11 progression) were included. VVN was detected in 54 patients (90%), the total number of VVN was significantly higher in progressive stenosis (8.9 ± 5.7 vs. 4.5 ± 3.8, p = 0.02). However, there was no relationship between the number of VVN and ischemic symptom. Conclusions: VVN was more frequently observed in progressive stenosis. Evaluation of VVN using OFDI might be useful to predict progression of carotid artery stenosis.
