A 63 year old woman had been intensively treated for recurrent carcinoma of the neck. Following acute vascular surgery of the carotid artery, she developed the vasodilatory type of the carotid sinus syndrome. The presentation of this type of the syndrome was remarkable, since it is usually associated with primary or metastatic carcinoma in the neck region. Previous cancer treatment may have modified the course of disease in this patient, which ultimately had a lethal outcome. 相似文献

Atherosclerotic disease, as a systemic process, affects all arteries to varying degrees. In particular,coexistent carotlid aria coronary artery diseases are common; Management of such patients has been a point of continuing controversy. Current American Heart Association (AHA) guidelines recommend carotid endarterectomy (CEA) in symptomatic patients with carotid artery stenosis of 50%-99% and in asymptomatic patients with stenosis of 60%-99%. Carotid artery stenting (CAS) has become a reasonable alternative to CEA, particularly in patients at high risk for CEA. We sought to assess feasibility, safety and midterm outcome of carotid artery stenting in patients with coexisting symptomatic coronary disease and carotid artery stenosis. 相似文献

OBJECTIVE: To investigate the efficacy of continuous propofol infusion via the common carotid artery for general anesthesia. METHODS: Forty adult patients scheduled for abdominal surgery were randomly assigned into 2 groups to receive propopol via the common carotid artery (IC group, n=20) or via the median cubital vein (IV group, n=20). Anesthesia was induced with intravenous administration of drugs and maintained with continuous propofol infusion via the common carotid artery or the median cubital vein, with the CSI stabilized at 40-/+5 till the end of the operation. During the anesthesia, intravenous injection of fentanyl (3 microg.kg(-1).h(-1)) and vecuronium (50 microg.kg(-1).h(-1)) were given intermittently to maintain the analgesia and muscular relaxation. The dose of propofol used, hemodynamics and recovery of the patients were observed. RESULTS: The dose of propofol used during the surgery to maintain a CSI of 40-/+5 was significantly lower in group IC and than in group IV (2.57-/+0.67 vs 5.72-/+1.37 mg.kg(-1).h(-1), P<0.01). In group IC, the blood pressure was elevated in more than half of the patients and in some cases, the elevation exceeded one third of baseline value and needed intervention with hypotensive drugs. In the IV group, the patients' blood pressure remained stable and varied within the amplitude of 15% of the baseline level. Recovery of spontaneous breathing and consciousness was more quickly in group IC than in group IV (P<0.05). CONCLUSION: Loss of consciousness and nervous reflex can be achieved with propofol infusion via the common carotid artery, which reduces propofol dose by about 50% in comparison with intravenous infusion and allows more rapid recovery of spontaneous breath and consciousness. 相似文献

目的 观察人颈总动脉持续输注异丙酚的麻醉效果.方法 择期腹部手术患者40例,随机分为颈总动脉组(IC组,n=20)和静脉组(IV组,n=20).静脉麻醉诱导气管插管控制呼吸后,通过颈总动脉或肘正中静脉持续输注异丙酚直至麻醉深度指数(CSI)等于40±5,并维持CSI在此水平波动直至手术结束停药.术中间断静脉注射芬太尼(3μg·kg-1·h-1)和维库溴铵(50μg·kg-1·h-1)维持镇痛和肌肉松弛.观察两组患者在整个手术维持期间异丙酚的用量、血流动力学变化和苏醒情况.结果 颈总动脉和静脉给药达CSI=40±5并维持至术终异丙酚的用量分别为(2.57±0.67)mg·kg-1·h-1和(5.72±1.37)mg·kg-1·h-1(P<0.01).在此麻醉深度下,IC组在维持麻醉初期近半数患者血压持续升高,有的甚至大于其基础值的30%以上,而Ⅳ组血压基本平稳.维持在低于基础血压15%水平波动.停药恢复阶段,IC组自主呼吸恢复和清醒速度均明显快于Ⅳ组(P<0.05).结论 颈总动脉持续输注异丙酚与静脉给药一样可用于麻醉维持,但用药量仅为静脉给药的1/2. 相似文献

目的 采用计算流体力学数值模拟方法对颈动脉支架植入术(CAS)治疗颈动脉狭窄的效果进行评估.方法 采用Mimics软件对1例颈动脉狭窄患者手术前后的CT影像进行三维重建,构建个体化颈动脉分叉模型,利用计算流体力学方法对模型进行三维流动数值模拟计算,以壁面剪切应力、壁面压力、血流轨迹和流量等血流动力学指标对CAS的疗效进行评估.结果 数值模拟计算结果显示:与术前比较,CAS术后颈动脉内的流动速度、颈内与颈外动脉的流量分配比例、壁面剪切力和壁面压力等血流动力学指标发生明显变化,血液流动状态明显改善.结论 计算流体力学数值模拟评估CAS的效果更为直观且合理,并能够在术前为个体病例提供最优的指导性方案. 相似文献

目的观察颈动脉支架置入术(CAS)治疗颈动脉狭窄前后颈动脉超声变化及临床疗效。方法2010年1月—2013年12月收治颈动脉狭窄患者62例,均予CAS治疗,采用颈动脉超声检测CAS前后狭窄处管径及血流参数变化,并进行对比分析。结果 62例CAS中,2例手术失败改行颈动脉内膜剥脱术(CEA),其余60例均获成功,共置入支架60个。颈动脉超声检测结果发现,患侧颈动脉狭窄处术后收缩期峰值流速(PSV)、舒张期最低血流速度(EDV)明显降低,血管内径(R)、血管搏动指数(PI)和前向血流明显增大(P<0.05),术后1周时与对侧比较差异无统计学意义(P>0.05)。术后1年复查,与术后1周比较差异亦无统计学意义(P>0.05)。1年后随访,经颈动脉超声复查发现手术侧再狭窄1例(3.3%)。结论 CAS是治疗颈动脉狭窄的一种安全可靠手段,而颈动脉超声检查可在CAS前后对狭窄程度及血流动力学情况进行有效的评估。 相似文献
