肺栓塞(PE)患者中有右室超负荷表现者的预后很差,因此评价PE右室功能很重要。为此研究肺灌注缺损范围的测定能否对右室超负荷程度进行预测。 方法 在1988年8月～1993年1月连续抽取121例经肺闪烁术(LS)或肺血管造影术确诊PE后即行多普勒超声心动图(ED)检查心功能的患者。分别用两种方法对肺扫描结果进行分析,来估计灌注缺损范围。(1)分
Patients with PE have a poor prognosis of right ventricular overload, and therefore evaluating RV right ventricular function is important. To study whether the range of lung perfusion defects can predict the extent of RV overload. Methods From August 1988 to January 1993, 121 consecutive patients who underwent pulmonary scintigraphy (LS) or pulmonary angiography to diagnose PE were examined by Doppler echocardiography (ED). Two methods were used to analyze lung scan results to estimate the extent of perfusion defects. (1 point
