摘要
目的评价用Straub螺旋电吸式祛栓术治疗急性大面积肺梗死的疗效和安全性。方法5例患者经CT和肺动脉造影确诊为大面积肺血管栓塞。所有患者均有急性肺梗死的症状。采用Straub Rotarex对5例患者进行了经皮机械祛栓,1例使用了辅助局部溶栓。结果所有患者在技术上和临床症状改善上均取得了成功。机械祛栓后患者的平均肺动脉压从(41.8±7.9)mmHg降低至(30.7±8.5)mmHg(P<0.01),动脉血氧分压(PaO2)从(56.6±9.3)mmHg增加至(85.8±5.0)mmHg(P<0.01)。血氧饱和度(SaO2)从(79.0±4.3%)升至术后的(92.8±3.5)%(P<0.01)。结论初步经验显示Straub螺旋电吸式祛栓术在急性大面积肺梗死治疗中具有较好的安全性与疗效。
Objective To assess the safety and efficacy of rotational power-driven aspiration thrombectomy by using Straub Rotarex system in the treatment of acute massive pulmonary embolism. Methods Percutaneous mechanical thrombectomy was performed in 5 patients with CT.and angiographically- proved symptomatic massive pulmonary embolism by using Straub Rotarex system. Additional supplementary local thrombolysis was employed in one case. The mean pulmonary arterial pressure （PAP）, partial pressure of oxygen in arterial blood （PaO2） and oxygen saturation of blood （SaO2） were determined before and after the procedure. The results were analyzed. Results Both technical success and clinical improvement were obtained in all patients without serious complications. After the treatment, the mean PAP decreased from （41.87 ± 7.9） mmHg to （30.7 ± 8.5） mmHg （P 〈 0.01）, while the PaO2 increased from （56.6 ± 9.3） mmHg to （85.8 ± 5.0） mmHg （P 〈 0.01）, and SaO2 from （79.0 ± 4.3） mmHg to （92.0 ± 3.5） mmHg （P 〈 0.01）. Conclusion The initial experience has indicated that rotational power-driven aspiration thrombectomy with the help of Straub Rotarex device is safe and effective for the treatment of acute massive pulmonary embolism.
