ABSTRACT
Objective To evaluate left ventricular function of acute myocardial infarction (AMI) patients who underwent autologous bone marrow mononuclear cells (BMMNC) after percutaneous coronary intervention (PCI) transplantation with tissue Doppler imaging (TDI). Methods Forty-eight male patients with AMI were divided into experimental group and control group (each n=24). PCI was performed within 24 hours after attach. Patients in experimental group received autologous BMMNC transplantation 7-14 days after PCI. Conventional echocardiography and TDI were performed before and 1, 3 and 6 months after treatment. Left ventricular ejection fraction (LVEF), peak systolic (S_a, S_m), early diastolic (E_a, E_m) and late diastolic (A_a, A_m) mitral velocities and regional myocardial velocities were obtained with conventional echocardiography or TDI, and compared between the two groups. Results There was no significant difference of each index between two groups before operation. Compared with the control group, S_a, S_m, E_m, E_a/A_a and Em/Am improved significantly in experimental group at each follow-up time point; LVEF and E_a were significantly higher than those of control group 3 and 6 months after treatment. Conclusion Combination of PCI and autologous BMMNC transplantation is more helpful to improve regional and global cardiac systolic and diastolic function after myocardial infarction, which can be quantitatively evaluated with TDI.
ABSTRACT
Objective To observe the therapeutic efficacy of bronchial artery embolization(BAE) and pulmonary artery embolism(PAE) for massive hemoptysis.Methods 48 cases with massive hemoptysis were treated with embolization,of them,43 underwent selective bronchial arteriography and BAE with microballoon of Baiji,three cases underwent selective bronchial arteriography and treated with PAE at the same time,two cases underwent PAE.Results The abnormal features of arteriography were displayed in all hemoptysis stopped after operation 48 h later.Three cases recurred during followed up six months later,but the hemoptysis decreased.Conclusion Pulmonary arteriography and PAE therapy should be preformed when BAE fails for massive hemoptysis.
ABSTRACT
Objective To study the diagnostic value of cavernosography in the venous leakage impotence.Methods Cavernosography were performed for 25 patients with the venous leakage impotence who had been diagnosed by the clinic just after the contrast agent had been injected.The appearance of cavernosography were analysed.Results Different degree venous leakage had been shown in 25 cases.The diagnostic accordance rate of the cavernosography,clinic impotence for the venous leakage was 100%(25/25).The accordance rate of the degree of the venous leakage shown by the cavernosography and pointed out by the clinical impotence was 36%(9/25).Conclusion Cavernosography not only can show the venous leakage and its location,but also can know the degree of the venous leakage.
