目的 :探讨双侧基底节区对称性分水岭性脑梗死 (CWI)的病因与机理、MRI特征。方法 :回顾性分析 12例经MRI及临床证实的双侧基底节区对称性CWI的临床资料及MRI表现。结果 :12例的病因中以严重低血压及低血容量为主 ,MRI表现为双侧基底节区对称性T1WI为低 ,T2 WI为高信号 ,信号均匀 ,占位不明显 ,加强扫描无强化。结论 :双侧基底节区对称性CWI病因主要为严重低血压及低血容量。MRI能较早及敏感地显示其变化 ,其与一些好发于基底节区病变的MRI表现相似 ,鉴别时须结合临床资料。

Apnea test plays a very important role in diagnosing brain death. But, conventional method may result in severe complications such as hypotension, pulmonary artery hypertension as well as arrhythmia. This research was aiming to minimizing the complications of apnea test by artificial augmentation of PaCO 2 in dog model of brain death. Our results showed that the modified apnea test is a high reliable method. Compared with the conventional way, it efficiently keeps the circulation stabilization without increasing infusion rate of nor-epinephrine (NE) by significantly shorting the testing time. Notably, pulmonary artery hypertension didn't appear during testing. Our finding indicates that artificial augmentation of PaCO 2 is safer than conventional apnea test.

呼吸暂停试验在临床判定脑死亡诊断过程中起十分关键的作用。据报道 ,传统试验方法可引起严重低血压、肺动脉高压、心律失常等并发症。本研究在脑死亡动物模型中以吸入CO2 提高PaCO2 改进呼吸暂停试验 ,旨在减少对血流动力学的影响。结果表明 ,吸入CO2 法能有效刺激呼吸中枢 ,与传统试验方法比较 ,能显著缩短试验时间 ,对血压、心率影响较小 ,试验过程中血管活性药物的需要量无显著增加。更重要的是未发现肺动脉高压。上述结果提示 ,吸入CO2 法较传统方法更加安全 ,是一种可靠的呼吸暂停试验法

Objective Hypotension and bradycardia related carotid sinus reaction during carotid artery stenting may cause varying degrees of hemodynamic instability. The study investigated the incidence, predictors, management and influence of clinical outcome.Methods 326 patients with extracranial artery stenosis (more than 50%) were treated with self-expanded stents. The baseline, and periprocedual blood pressure changes were recorded. The incidence, predictor amd treatment of hypotentsiong (<90mmHg) were investigated, retrospectively. Results Blood pressure changed in 206 patients, among which 8 presented with hypertentsion (1 had intracranial hemotoma because of hyperperfusion), and 198 cases with blood pressure. Forty-five patients had hypotension (systolic blood pressure≤90mmHg (4min~11days). The patient recovered well without any neurologic deficit related hypotension with continuous infusion of Dopan. The blood pressure in 6 patients with a history of hypertension returned to normal level (6~25months, 13.9 months). The most important predictor of CSR was bifurcation location of carotid stenosis (bifurcation 27 cases; ostial 13 cases; isolated internal carotid artery; 4cases). Severe hypotension occurred in 34 patients treated with balloon and stenting, while 4 patients with only carotid artery stenting.Conclusions We conclude that hypotentsion occurs frequently during CAS. Bifurcation location of stenosis is the most important predictor. However, hemodynamic instability does not increase the risk of periprocedural complications.
