We reported a 54-year-old female patient with severe tricuspid regurgitation, who received mechanic valve in the mitral position 15 years ago. The patient’s Society of Thoracic Surgeons score was 8.27%, and was intolerant to open heart surgery, so she was recommended for transcatheter tricuspid valve replacement via right vena jugularis interna. The procedures were guided by echocardiography and X ray fluoroscopy on November 13, 2021, the prosthesis was implanted successfully, and the patient was recoved without any adverse events. After 1 month follow-up, her general condition was apparently improved.
Objective To evaluate the clinical effect of Halo-vest in treatment of unstable upper cervical spine. Methods From March 1997 to October 2002, 16 cases of unstable upper cervical spineswere treated and immobilized by Halovest, aged from 14 to 53 years. There were 3 cases of isolated Jefferson fractures, 4 cases of isolated Hangman fractures and 1 case of Anderson type Ⅱ fracture. The 8 cases were immobilized for 3-4 months by Halovest. There were 3 cases of old odontoid fractures with dislocations treated by occipitocervical plate fixation and fusion, 1 case of C1 malignant tumor by posterior resection and internal fixation, 2 cases of C2 malignant tumor by anterior resection, fusion, and internal fixation; these cases were immobilized by Halo-vest during surgery. There were 1 case of C2,3 tuberculosis were treated by anterior debridement and fusion, and 1 case of gooseneck deformity by anterior decompression, fusion and screw fixation after resection of C2-7 , the 2 cases were immobilized for 3 months by Halo-vest.Of 16 cases, there were 8 cases accompanied with spinal cord syndrome. Results Fifteen cases were followed up 6 months to 5 years. Anterior arch ununion and posteriorarch osseous healing occurred in 1 case of Jefferson fracture. Other fractures and embedded bones became osseous fusion. One case of C2 malignant tumorrecurred 8 months after operation. Spinal cord syndrome of all patients disappeared. Conclusion Halo-vest immobilization is an effective method for conservative treatment and stable reconstruction of unstable upper cervical spine.
ObjectiveTo investigate the feasibility and safety of transcatheter aortic valve replacement (TAVR) through apical approach for aortic regurgitation of large annulus.MethodsFrom November 2019 to May 2020, 10 male patients aged 64.50±4.20 years with aortic valve insufficiency (AI) underwent TAVR in the Department of Cardiovascular Surgery, Xijing Hospital. The surgical instruments were 29# J-valveTM modified and the patients underwent TAVR under angiography. The preoperative and postoperative cardiac function, valve regurgitation, complications and left ventricular remodeling were summarized by ultrasound and CT before and after TAVR.ResultsA total of 10 valves were implanted in 10 patients. Among them, 1 patient was transferred to the aortic arch during the operation and was transferred to surgical aortic valve replacement; the other 9 patients were successfully implanted with J-valve, with 6 patients of cardiac function (NYHA) class Ⅱ, 4 patients of grade Ⅲ. And there was a significant difference between preoperation and postoperation in left ventricular ejection fraction (44.70%±8.78% vs. 39.80%±8.48%, P<0.05) or aortic regurgitation (1.75±0.72 mL vs. 16.51±8.71 mL, P<0.05). After 3 months, the patients' cardiac function was good.ConclusionTAVR is safe and effective in the treatment of severe valvular disease with AI using J-valve.
【Abstract】 Objective To investigate the early effectiveness of the Discover cervical artificial disc replacement in treating cervical spondylosis. Methods Qualified for the selective standard, 24 patients with cervical spondylosis were treated between March 2010 and March 2011. Of 24 patients, 13 patients underwent anterior cervical decompression and fusion (ACDF) (ACDF group, between March 2010 and September 2010) and 11 patients underwent Discover cervical artificial disc replacement (CADR group, between September 2010 and March 2011). There was no significant difference in gender, age, disease duration, lesions typing, and affected segments between 2 groups (P gt; 0.05). The operative time, blood loss, and complications were recorded. Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and Odom’s scores were used to evaluate the postoperative effectiveness. In CADR group, the cervical range of motion (ROM) in all directions, and prosthesis eccentricity were measured before and after operation. Results Symptoms disappeared and no complication occurred after operation in the patients of 2 groups. The patients were followed up 12 to 18 months (mean, 15.3 months) in ACDF group and 6 to 12 months (mean, 9.6 months) in CADR group. The NDI scores in CADR group were significantly higher than those in ACDF group at 1, 3, and 6 months (P lt; 0.05), but no significant difference was observed in JOA score improvement rate between 2 groups (P gt; 0.05). According to Odom’s score at last follow-up, the results were excellent in 6 cases, good in 4 cases, and fair in 3 cases with an excellent and good rate of 76.92% in ACDF group, and were excellent in 9 cases, good in 1 case, and poor in 1 case with an excellent and good rate of 90.91% in CADR group, showing no significant difference (χ2=3.000, P=0.223). The patients in CADR group had significant limit of cervical joint ROM in flexion and extension and right bending at 1 month (P lt; 0.05), but cervical joint ROM restored after 3 months. The ROMs of left bending at 3 months and 6 months were bigger than preoperative value (P lt; 0.05). Meanwhile, ROM in left bending were bigger than that in right bending in replaced segment and upper segment (P lt; 0.05), and the ROM difference between left bending and right bending in upper segment was 2 times higher than that in the replaced segment; a marked linear correlation (P lt; 0.05) existed between the ROM difference and prosthesis eccentricity, and prosthesis bias had bigger ROM in lateral bending. Conclusion Discover cervical artificial disc replacement for treatment of cervical spondylosis can provide a good effectiveness and cervical postoperative movement function. As a new prosthesis, it has some merits such as simple operative steps and less complications.
To study the relationship between the level of serum thyrotropin receptor antibody (TRAb) and the severity of Crave′s disease. From August, 1996 to June, 1998, 156 outpatients with Crave′s disease were followed up. The level of serum TRAb were measured by radio-receptor-analysis (RRA). Results: ①The level of serum TRAb rose in 90.1% of the untreated group; ②The level of serum TRAb restored to normal after the antithyroid drugs were used and the thyroxine level in serum returned to normal; ③In recurrent patients with the treatment of131I, drugs or operation, the serum TRAb level increased. Conclusion: The level of serum TRAb has great significance in the diagnosis, treatment and follow up of the Crave′s disease.
Pure native aortic valve regurgitation (NAVR) is one of the common heart valve diseases, and the prognosis of symptomatic chronic NAVR is poor. Although transcatheter aortic valve replacement (TAVR) is currently an "off-label" procedure, it remains the option for patients with high risk for surgery. In this case, an 81-year-old man with multiple comorbidity and high Society of Thoracic Surgeons score, the risk for surgery is rather high. Through the preoperative evaluation by the multidisciplinary heart team, considering that the patient had calcification at the junction of annulus, as well as mild aortic stenosis, after careful consideration, 29# Venus A-Valve was chosen. After the procedure, the symptoms were obviously improved and the follow-up effect was good. Due to various causes of NAVR, great anatomical variation of annulus, little calcification of aortic valve, and lack of anchor point and other problems, the procedure to treat NAVR with TAVR is still difficult. At the same time, there are few valve systems developed for the anatomical characteristics of aortic regurgitation valve. TAVR in the treatment of patients with high risk for surgery still requires long-term practice and technical development.
Transcatheter aortic valve replacement (TAVR) has become the preferred treatment for severe aortic stenosis. The localization and anchor of many transcatheter heart valves available in the clinic today are dependent on the calcific aortic valve leaflet of patients. We reported here a successful case of transapical aortic valve implantation with Ken-Valve heart valve in an 82-year-old male patient with pure severe aortic regurgitation without native valve calcium. Postoperative follow-up (3 months after the surgery) showed that the cardiac function significantly improved. The echocardiography indicated that the Ken-Valve prosthesis worked well without perivalvular regurgitation. The short-term clinical effect was satisfactory. The Ken-Valve with three position anchors is proved to be suitable for the treatment of pure aortic regurgitation.
ObjectiveTo compare the in-hospital outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) for bicuspid aortic valve (BAV) patients and tricuspid aortic valve (TAV) patients. MethodsPatients (including BAV and TAV patients) who underwent TA-TAVR with the J-ValveTM in West China Hospital from July 2014 to July 2020 were included consecutively. The clinical outcomes of the patients were analyzed. ResultsA total of 354 patients were included in the study, 75 in the BAV group and 279 in the TAV group. There were 229 males and 125 females with a mean age of 72.2±6.0 years. No death occurred during the procedure, and the overall technical success rate was 97.7%. The all-cause in-hospital mortality rate was 1.4%. Twenty (26.7%) patients with BAV and 46 (16.5%) patients with TAV had mild or higher perivalvular leaks immediately after the procedure. No patients with BAV required permanent pacemaker implantation postoperatively, while 13 (4.7%) TAV patients required permanent pacemaker implantation, with an overall pacemaker implantation rate of 3.7%. One (1.3%) BAV patient and 7 (2.5%) TAV patients developed acute kidney injury postoperatively. One (1.3%) BAV patient and 1 (0.4%) TAV patient developed perioperative myocardial infarction. The average postoperative hospital stay was 7.6±3.6 d for BAV patients and 8.6±6.1 d for TAV patients. There was no statistical difference in primary or secondary in-hospital outcomes between BAV and TAV patients (P>0.05). ConclusionCompared to TAV patients, BAV patients have similar in-hospital outcomes, with a low incidence of adverse clinical outcomes, which provides preliminary evidence for its implementation in Chinese patients with a high proportion of BAV.
ObjectiveTo summarize the technique and effectiveness of double metatarsal osteotomy for treating severe hallux valgus with increased distal metatarsal articular angle (DMAA).MethodsBetween June 2014 and December 2017, 64 patients (94 feet) of severe hallux valgus with an increased DMAA were treated with the double metatarsal osteotomy (distal metatarsal Reverdin osteotomy+proximal metatarsal open wedge osteotomy) combined with Akin osteotomy and soft tissue surgery to correct the deformity. There were 10 males (15 feet) and 54 females (79 feet) with an average age of 44.5 years (range, 26-66 years), including 34 of unilateral foot and 30 of bilateral feet. The Maryland metatarsophalangeal joint score of the American Orthopaedic Foot and Ankle Society (AOFAS) was 54.3±7.4 and the visual analogue scale (VAS) score was 6.0±2.0. The pre- and post-operative AOFAS score, VAS score, DMAA, hallux valgus angle (HVA), first-second intermetatarsal angle (1-2IMA), and the first metatarsal length (FML) were recorded and compared.ResultsAll incisions healed by first intention. All patients were followed up 12-15 months, with an average of 13.2 months. The complications occurred in 4 feet, including 1 foot of hallux stiffness, 1 foot of numbness at the edge of the wound, 1 foot of metastatic metatarsalgia, and 1 foot of metatarsal bone necrosis. At 1 year after operation, the Maryland metatarsal joint score of AOFAS was 89.2±7.4, showing significant difference compared with preoperative score (t=18.427, P=0.000); and the effectiveness was rated as excellent in 78 feet, good in 12 feet, poor in 3 feet, and bad in 1 foot, with an excellent and good rate of 95.7%. The VAS score was 1.5±2.0, showing significant difference compared with the preoperative score (t=10.238, P=0.000). The X-ray films showed that the osteotomies achieved bony healing at 3 months after operation. There were significant differences (P<0.05) in HVA, 1-2IMA, and DMAA between preoperation and 6 months and 1 year after operation; but no significant difference was found in FML between preoperation and 1 year after operation (t=0.136, P=0.863).ConclusionFor the patients with severe hallux valgus with increased DMAA, the double metatarsal osteotomy can significantly relieve the clinical symptoms and improve the imaging parameters with less postoperative complications.
ObjiectiveTo explore the efficacy and safety of ketogenic diet therapy (KDT) in the rapidly progressive stage of childhood developmental epileptic encephalopathy Dravet syndrome (DS). Methods The clinical data of all patients who added KDT in the Children’s Hospital of Fudan University from 2011 to 2022 were retrospectively collected, and the age of <6 years was used as the criterion for the rapid progression of the disease. The clinica data, genotype and the efficacy of KDT were analyzed in DS patients who met the criteria. Results A total of 32 patients met the criteria for rapid disease progress, including 22 males and 10 females. The age at onset was (5.69±2.10) months. All patients had multiple seizure phenotypes and monthly seizures despite reasonable Antiseizure medications treatment. After 3, 6, 12, and ≥24 months, 93.8% (30/32), 87.5% (28/32), 53.1% (17/32), 34.4% (11/32) remained on the KDT, while 76.7% (23/30), 75.0% (21/28), 70.6% (12/17), 54.5% (6/11) showed >50% reduction in seizure. Status epileptius (SE) was reduced by 100% at 3 months, 71.0% at 6 months, 86.0% at 12 months. After 12 months, 14 patients experienced efficacy degradation. After 3 months, the EEG background rhythm showed improvement in 75.0% patients, interictal epileptic discharges was decreased in 54.5% patients and cognitive function was improved in 78.6% patients. At the initial stage of KDT, 62.5% (20/32) patients had transisent adverse reactions, including diarrhea, vomiting, fatigue, lethargy, hypoglycemia, and metabolic acidosis, but no mid- and long-term adverse reactions were found. ConclusionKDT is an efficective and safe treatment for DS. KDT can effectively control seizures, reduce the incidence of Status SE and shorten the duration of SE. With the prolongation of the KDT course, some patients experienced a degraded effect. KDT can improve abnormal EEG and cognitive function in DS patients. Pharmoco-resistant DS patients are suggested to receive KDT in the early stage of disease progression.
