肺血栓栓塞症的核素影像诊断及临床基础

目的:利用肺核素影像扫描检查及肺动脉造影等其它临床手段,对肺血栓栓塞症(PTE)进行明确诊断;从临床基础探讨PTE致病的危险因素。方法:对1993～2002年问,我院37例肺血栓患者进行临床资料分析。结果:在37例患者中,进行核素影像明确诊断32例(86.4％)。在21～50岁年龄段,女性发病率小于男性,有统计学意义(P<0.05);19例(51.4％)患者存在深静脉血栓。结论:核素影像仍是目前首选的诊断肺栓塞的筛选手段,其结果有较重要的诊断或排除诊断意义。女性PTE的发病年龄晚于男性,与雌激素降低胆固醇血浓度及月经周期改变凝血机制等有关。下肢深静脉血栓作为主要的危险因素,与PTE的发生密切相关。

Radionuclide Imaging Diagnosis and Clinical Basis of Pulmonary Thromboembolism

Objective: To diagnose the pulmonary thromboembolism(PTE) by using the radionuclide imaging scan and other clinical techniques. Utilize clinical basis to discuss the risk factors of PTE. Methods: The clinical data of 37 inpatients with PTE from 1993 to 2002 were reviewed. Results: The results of 37 cases of PTE were analyzed. Of 37 cases, 32 (86. 4% )were diagnosed definitly as PTE. From age 21 to 50,male patients were significantly more than female. In the 37 patients, there were 19(51. 4% ) patients had lower limbs deep venous thrombosis. Conclusions: The radionuclide imaging was still the preferred filtration's diagnosis of PTE. It's results were important significance of diagnosis or exclusion. Female patients were taken bad later than male. It was related to the action of estrogen. As the risk factors, lower limbs deep venous thrombosis was related closely to PTE.
