ABSTRACT
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.
ABSTRACT
Objectives:To analyze the safety and efficacy of chemical ablation of anhydrous alcohol combined with gelatin sponge for patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods:The clinical data of 7 HOCM patients, who underwent chemical ablation with anhydrous alcohol and gelatin sponge in Fuwai Hospital from May 2017 to December 2017, were analyzed. Results:There were 5 males and 2 females, with a median age of 56 years (range, 43-67 years), the mean interventricular septum thickness was (19.6 ± 4.8) mm, the number of ablated septal branch was 1-2, the amount of used anhydrous alcohol was 1.4 (1.0-2.0) ml, the amount of applied gelatin sponge was 0.5 (0.1-1.3) ml. After procedure, the left ventricular outflow tract pressure was significantly decreased ([31.6 ± 12.6] mmHg vs [86.4 ± 20.7] mmHg, P＜0.001), NYHA cardiac function was significantly improved (1.4 ± 0.5 vs 2.7 ± 0.8, P ＜0.05), no relevant complications occurred. Conclusions:Chemical ablation with anhydrous alcohol and gelatin sponge is safe and effective for patients with hypertrophic obstructive cardiomyopathy.
ABSTRACT
Objective To evaluate the efficacy of radiofrequency ablation combined with absolute ethanol injection in the treatment of hepatocellular carcinoma (HCC), and to study the value of contrast-enhanced ultrasound in the evaluation of therapeutic effect.Methods From May 2015 to May 2017, 60 patients with liver cancer (72 lesions) were treated in our hospital.The patients were divided into 3 groups, the RFA treatment group (n=20), 24 lesions, the PEI treatment group (n=20), 22 lesions, and the RFA+PEI treatment group (n=20) with26 lesions.3 groups of patients were treated with contrast-enhanced ultrasound (CEUS), routine color Doppler ultrasound (CDUS), enhanced CT to evaluate the specific situation of the tumor, and evaluate the therapeutic effect again after operation.The rates of necrosis, lesion inactivation and residue were evaluated in each group.Results The necrosis rate of RFA group, PEI group and RFA+PEI group were66.67%,81.82% and 96.15%, respectively.The necrosis rate of CT group was the highest, and the difference was statistically significant (P<0.05) in RFA+PEI group.Comparison of different imaging to assess the sensitivity and specificity of CDUS, to evaluate the sensitivity and specificity were 81.36% and 53.85%;CEUS to evaluate the sensitivity and specificity were 98.31% and 84.62%, significant difference was statistically significant (P<0.05).Conclusion RFA+PEI treatment program is better than RFA and PEI alone treatment, the treatment effect is better, CEUS in the evaluation of RFA+PEI treatment effect, has higher clinical value.
ABSTRACT
Objective To observe the effect of atropine in the treatment of bromiderosis with anhydrous alcohol injection. Methods Patients were randomly divided into two groups (A and B): the patients in Group A was injected with both anhydrous alcohol and atropine, and that in Group B was only injected with anhydrous alcohol. The effect of the operation was evaluated at 1, 3 and 6 months after the treatment. Results From August 2004 to January 2008, 72 patients were involved in this study. 37 cases were included in Group A, and 35 patients were included in Group B. The effective rate in the Group A was 83.78 %, and that in the Group B was 82.86 %. There was no statistical difference between these two groups. Conclusion Atropine has no effect on the treatment of axillary bromidrosis with anhydrous alcohol injection and it is, therefore, not necessarily included in the treatment.
ABSTRACT
PURPOSE: As a treatment of giant cell tumors (GCT) of the long bone, anhydrous alcohol was used in our institution due to the potential complications associated with other previous adjuvants. Therefore, this study evaluated the feasibility and effectiveness of anhydrous alcohol as a new adjuvant in the treatment of a GCT. MATERIALS AND METHODS: One hundred and three GCT patients were treated and followed up for an average of 6 years (range, 1-29.3 years) with a mean age of 33 years (range, 16-67 years). Curettage, additional burring, and reconstruction with a bone graft or cementing were performed in 69 patients. Among them, anhydrous alcohol was used as an adjuvant in 38 patients. RESULTS: Four (10.5%) patients given the anhydrous alcohol treatment had a local recurrence, whereas 15 recurrences (48.4%) developed in 31 patients treated without the anhydrous alcohol (p=0.001). There were no anhydrous alcohol-related complications. According to Kaplan-Meier's analysis and the log rank test, the anhydrous alcohol adjuvant showed a significant effect (p=0.014) in preventing the recurrence of GCT. CONCLUSION: The data suggests that anhydrous alcohol can be used as an effective adjuvant without potential risks for the treatment of a GCT of the long bone.

Objective: To study the diagnosis and treatment of primary hyperparathyroidism.Methods: The clinical data of 8 primary hyperparathyroidism patients(1992 2002) in our hospital were summarized and the references were reviewed.Results: It was found that primary hyperparathyroidism was liable to be misdiagnosed.Information on blood calcium,parathyroid hormone(PTH) and imaging may be helpful for diagnosis. Surgical resection(4 cases), anhydrous alcohol injection (2 cases), electron radiation (1 case) and internal medicine (1 case) were applied. Conclusion:Information on blood calcium,PTH and early imaging is helpful for diagnosis.Operation is the first choice of treatment, and for patients who can not tolerate surgery, anhydrous alcohol injection is an effective and safe treatment.
