Objective To evaluate interventional therapy for acute massive and submassive pulmonary embolism.Methods From June 2011 to June 2014.53 patients were enrolled and divided into group massive pulmonary embolism (MPE,n =16) and group submassive pulmonary embolism (SPE,n =37),both receiving catheter thrombectomy + contact thrombolysis within 12 hours after diagnosis.Preand post-interventional measures were assessed,including mean pulmonary arterial pressure (MPAP),cardiac biomarkers,tricuspid regurgitation,right ventricular (RV) dilatation,and massive hemorrhage within 72 hours.Patients were followed up for 6 months for the occurrence of chronic thromboembolic pulmonary hypertension.Results In all 53 patients were successfully completed catheter thrombectomy +contact thrombolysis,the mean pulmonary artery pressure in group MPE decreased from (47 ± 6)mmHg to (34 ± 4) mmHg (P ＜ 0.05),and in group SPE decreased from (44.2 ± 1.5) mmHg to (31.4 ± 6.2) mmHg (P ＜ 0.05).The ventriculus dexter disfunction was alleviated in 78.4％ patient after therapy.Overall 1.9％ patients suffered from massive hemorrhage,(0) in group MPE,and (2.7％)in group SPE.The incidence of chronic thromboembolic pulmonary hypertension during 6 moths follow up was 0.Conclusion Early interventional therapy for massive and submassive pulmonary embolism decreased pulmonary artery pressure,relieved right ventricular dysfunction,reduced bleeding complications and the incidence of chronic thromboembolic pulmonary hypertension.

Objective To evaluate ultrasonography combined with magnetic resonance imaging(MRI) diagnosis value for fetal brain deformities.Methods The results of ultrasonography and MRI was analysied in 12 fetuses with deformities,which were compared to postnatal,autopsy or other hospital inspection results and evaluated the accuracy.Results In 8 cases,the diagnoses established by ultrasonography were correct.3 cases were misdiagnosed by ultrasonography,1 case was missed the diagnosis.In 11 cases,the diagnoses established by MRI were correct and 1 case was missed the diagnosis.Conclusion Ultrasonography must be choosed in diagnosising fetal skull brain deformities,MRI was supplement to ultrasonography in complicated pregnancies.The combination of ultrasonography and MRI have an important value in guiding pregnant women to determine whether or not to continue the pregnancy.
