食管造影定位房间隔穿刺点两种方法的比较

Comparison of two methods of esophageal radiography for locating transseptal puncture points

目的食管造影定位房间隔穿刺点时可选用泛影葡胺或硫酸钡，探讨哪种造影剂更有利于房间隔穿刺点的定位。方法350例因行经皮球囊二尖瓣成形术（PBMV）需要房间隔穿刺的患者，随机分为研究组和对照组。采用食管造影法定位房间隔穿刺点，研究组患者一次吞服76％泛影葡胺，对照组患者一次吞服稀硫酸钡溶液。结果与对照组相比较，研究组的房间隔穿刺点定位的成功率（97．1％VS90．9％，P〈0．05）、房间隔穿刺的成功率显著提高（95．4％VS87．4％，P〈0．01）。对照组平均手术时间（47±18）min，研究组平均（41±16）min，研究组的手术时间显著缩短（P〈0．01）。结论泛影葡胺更有利于食管造影法定位房间隔穿刺点。

Objective Both meglumine diatrizoate and barium sulfate are used as the contrast agent during esophageal radiography. We investigate which contrast agent is better in locating transseptal puncture points in patients undergoing percutaneous balloon mitral valvuloplasty （ PBMV ）. Methods A total of 350 patients were randomized to receive oral meglumine diatrizoate （ study group ）, or barium sulfate as a contrast （ control group ） during esophageal radiography. Results The successful rate of locating puncture points and that of transseptal puncture were markedly higher in the study group and in the control group （ 97.1% vs. 90.9%, P〈 0.05; and 95.4% vs. 87.4%, P〈 0.01 ）. The mean surgical duration was significantly shorter in the study group than in the control group [（ 47 ± 18 ）min vs. （ 41 ± 16 ） rain, P〈 0.01]. Conclusions Meglumine diatrizoate is better for locating of transseptal puncture points during esophageal radiography.
