RESUMO
Objective To investigate the safety and efficacy of Embosphere microsphere in the treatment of massive hemoptysis during bronchial arterial embolization(BAE).To analyze the factors influencing the recurrence by Cox regression model.Methods Ninety patients with massive hemoptysis who underwent BAE using Embosphere microsphere were included.The immediate hemo-stasis rate within 24 hours,clinical success rate and prognostic factors were statistically analyzed.Results The immediate hemosta-sis rate within 24 hours was 94.4％(85/90).The clinical success rate was 56.7％(51/90).Cumulative hemoptysis-free recurrence con-trol rates at 6 months,1 year and 2 years postoperative were 81％,78％and 57％,respectively.Cox regression model analysis showed that the variables associated with recurrence were long-term hemoptysis,lung cancer,tuberculosis and lung destruction.Conclusion Embosphere microsphere are safe and effective embolic particles in the treatment of massive hemoptysis during BAE.Risk factors for hemoptysis recurrence include long-term hemoptysis,lung cancer,tuberculosis and lung destruction.
RESUMO
Objective:To compare the clinical efficacy and safety of percutaneous transluminal septal branch anhydrous alcohol ablation (PTSAAA) and percutaneous transluminal septal branch microsphere embolization (PTSBME) in the treatment of patients with symptomatic hypertrophic obstructive cardiomyopathy.Methods:The clinical data of 55 patients with symptomatic hypertrophic obstructive cardiomyopathy treated by PTSAAA and PTSBME were retrospectively analyzed, among whom 27 were treated with PTSAAA and 28 with PTSBME. The changes of postoperative indicators of the two groups of patients were compared, including the improvement degree of symptoms [shortness of breath after activity (cardiac function NYHA classification), chest tightness, chest pain (angina CCS classification) and amaurosis, the decrease of left ventricular outflow tract pressure gradient (LVOTPG)], the ventricular septum thickness shown by color Doppler echocardiography, the incidences of complications at postoperative month 6 and 12, and the incidences of cardiovascular events at follow-up month 12. LSD- t, χ 2 or Fisher exact probability methods were used to compare the differences of indicators between the two groups. Results:Compared to the relative indicators before operation, there were significant differences in shortness of breath after activity, chest pain and amaurosis, LVOTPG, ventricular septum thickness, the incidences of complications at postoperative month 6 and 12 and the incidences of cardiovascular events at follow-up month 12 in both the PTSAAA group and PTSBME group ( P<0.05). The PTSBME group was not inferior to the PTSAAA group in the improvement degree of amaurosis, cardiac function NYHA classification and angina CCS classification and left ventricular ejection fraction (LVEF) at postoperative month 6 and 12 ( P>0.05) as well as in the LVOTPG decrease and the ventricular septum thickness at postoperative month 6 [(16.8±7.5) mmHg vs (15.8±7.3) mmHg, (19.8±4.9) mm vs (17.4±4.1) mm, P>0.05], but was superior to the PTSAAA group in the LVOTPG decrease and the ventricular septum thickness at postoperative month 12 [(15.2±6.7) mmHg vs (9.8±5.4) mmHg, (18.4±5.1) mm vs (12.2±3.2) mm, P<0.05]. There were statistical significances in the incidences of cardiovascular events and third degree atrio-ventricular block and nosocomial mortality between the two groups (6 vs 1; 5 vs 0, P<0.05), and the PTSBME group was superior to the PTSAAA group in safety. Conclusion:PTSBME may be a safe and effective method for the management of patients with symptomatic hypertrophic obstructive cardiomyopathy.
RESUMO
Objective To compare and analyze the efficacy of PVA particles and Embosphere microspheres for partial splenic embolization (PSE)in the treatment of hypersplenism secondary to liver cirrhosis.Methods Sixty patients underwent PSE for treatment of hypersplenism secondary to liver cirrhosis were analyzed retrospectively.According to different PSE embolization materials,they were divided into two groups:30 patients with PVA particles embolization (group A),and other 30 patients with Embosphere microspheres embolization (group B).The changes of white blood cells (WBC),platelets (PLT),spleen thickness,portal vein diameter and postoperative pain and fever were compared on the 3rd day,the 1st week,the 3rd week,the 1st month,the 3rd month,and the 6th month after PSE and compared between the two groups.Results The WBC and PLT of the 2 groups after PSE were significantly higher than those before PSE (all P＜0.05 ).The spleen shrank after 2 months,and there was no significant difference in spleen thickness and portal vein diameter between the two groups at the same time (all P＞0.05).The postoperative pain in group A was significantly less than that in group B (P＜0.05).Conclusion Both PVA particles and Embosphere microspheres have good curative effect in the treatment of hypersplenism secondary to liver cirrhosis. The price of PVA particles is lower than that of Embosphere microspheres,and the postoperative pain degree is lighter than that of Embosphere microsphere,which suggests PVA particles with more advantages in clinical application.
RESUMO
Objective To observe the curative effect and safety of interventional therapy of uterine fibroids using Embosphere and Pingyangmycin lipiodol emulsion.Methods The clinical data of 120 cases with uterine fibroids treated in our hospital were reviewed,and the patients were according to the different treatments given,divided into two groups (each with 60 cases).Patients in control group were treated with interventional therapy of Pingyangmycin lipiodol emulsion,while patients in the study group were given interventional therapy of Embosphere.The clinical efficacy and safety in the two groups were compared.Results The total efficiency in the study group was 93.33%,which was significantly higher than that in the control group (75.00%),and the difference was statistically significant (P<0.05).The comprehensive indexes after the treatment were improved in both groups compared with those before the treatment,and the improvement in the study group was significantly better than the control group (P<0.05,P<0.01).Besides,the total incidence of adverse effects in the study group was 11.67%,which was significantly lower than that in the control group (26.67%)(P<0.05). Conclusion The interventional therapy using Embosphere has better effect on uterine fibroid compared with the therapy using Pingyangmycin lipiodol emulsion,which is worthwhile to be brought into clinical application.
