A myocardial 201TI SPECT examination was conducted both prior to and following surgery of two adult patients with an anomalous left coronary artery originating from the pulmonary artery (Bland-White-Garland syndrome). In this syndrome, the anterior wall is usually affected first. Preoperative examination demonstrated an inferoposterior perfusion defect. In both patients, the right coronary artery was markedly dilated, and a significant left-to-right shunt formation was observed. Both patients were diagnosed as possibly having coronary steal syndrome. A prolonged inadequate blood supply to the right coronary region may cause inferoposterior cardiomyopathy. In the postoperative examination, myocardial perfusion markedly improved in one patient whose preoperative SPECT showed redistribution in a delayed scan. Thallium-201 SPECT was therefore found to be useful in assessing both the preoperative and postoperative myocardial perfusion.
对两名患有起源于肺动脉的异常左冠状动脉（布兰德 - 怀特 - 加兰综合征）的成年患者进行了手术前后的心肌201铊单光子发射计算机断层扫描（SPECT）检查。在这种综合征中，前壁通常首先受到影响。术前检查显示下后壁灌注缺损。两名患者的右冠状动脉均明显扩张，并观察到明显的左向右分流形成。两名患者均被诊断为可能患有冠状动脉窃血综合征。右冠状动脉区域长期供血不足可能导致下后壁心肌病。在术后检查中，一名术前SPECT显示延迟扫描有再分布的患者心肌灌注明显改善。因此发现201铊SPECT在评估术前和术后心肌灌注方面均有用。
