摘要: 目的 评价腺苷负荷脑血流灌注显像的安全性.方法 以腺苷负荷作为介入手段,按照常规腺苷负荷心肌灌注显像的方式,对80例脑病患者进行隔日法静息和负荷脑血流灌注显像.观察、记录患者在负荷过程前、中、后的主观、客观不良反应.结果 80例患者中没有发现因不良反应而提前终止或延长负荷显像的病例.有46例(58%)出现不同程度轻微不良反应.其主要症状包括头晕20例(25%)、心悸12例(15%)、低血压1例(1%)、气短7例(9%)、发热4例(5%)、出汗3例(4%)、恶心4例(5%)、皮肤潮红6例(8%)、胸部不适19例(24%)、腹部不适6例(8%)、味觉异常3例(4%)、口干1例(1%).只有1例出现ST段轻度压低心电图改变.结论 腺苷负荷脑血流灌注显像安全性好,不良反应轻微.

Abstract: Objective To evaluate the safety of adenosine as pharmacological stress agents in stress cerebral perfusion imaging. Methods Eighty patients under investigation for suspected cerebral vessel disease were recruited. Each had a resting seen and a stress scan on different days. The adenosine stress protocol was as same as the protocol used in adenosine stress myocardial perfusion imaging. Subjective and objective side-effects were investigated during pharmacological stress procedure. Results All patients completed the 6 min infusion protocol without premature termination on safety criteria or due to intolerable symptoms. 46 patients had mild side effects. 20 patients (25%) had dizziness, 12 patients (15%) had palpitation, 1 patient (1%) was hypotensive, 7 patients (9%) had dyspnoea, 4 patients (5%) felt hot, 3 patients (4%) had sweat, 4 patients (5%) had nausea, 6 patients (8%) had flushing, 19 patients (24%) had chest pain, 6 patients (8%) had abdomen pain, 3 patients (4%) had abnormal taste and 1 patient (1%) were thirsty. Transient ST change occurred in only 1 patient. Conclusion Adenosine stress cerebral perfusion imaging is a safe diagnostic method with mild side effects -
