This article described the clinical diagnosis and treatment of a patient with bicuspid aortic stenosis occurring severe mitral regurgitation during transcatheter aortic valve replacement. Before transcatheter aortic valve replacement, the patient’s information about medical history, signs, evaluation of CT and echocardiography were collected. After discussion by the heart team, the trans-femoral aortic valve replacement was performed. After the valve was placed during the procedure, a severe mitral regurgitation occurred. No clear causes were found, and the patient’s hemodynamics was stable. The patient recovered well during follow-up, so surgery and other treatments were not considered. This article discussed the possible mechanism and solutions of mitral regurgitation during transcatheter aortic valve replacement, and owned certain value for similar cases to refer to.
Objective To summarize the clinical characteristics and management experiences of patients with severe tricuspid regurgitation (TR) after mitral valve surgery. Methods Thirty patients were followed up and reviewed for this report. There were 1 male and 29 female patients whose ages ranged from 32 to 65 years (47.1±92 years). A total of 28 patients had atrial fibrillation and 2 patients were in sinus rhythm. There were 13 patients of mild TR, 10 patients of moderate TR and 7 patients of severe TR at the first mitral valve surgery. Five patients received the tricuspid annuloplasty of De Vega procedure at the same time, 2 patients received Kay procedure. The predominant presentation of patients included: abdominal discomfort (93.3%, 28/30), edema (66.7%,20/30), palpitation (56.7%, 17/30), and ascites (20%, 6/30). Results Nine patients underwent the secondary surgery for severe TR. The secondary surgery included tricuspid valve replacement (6 cases), mitral and tricuspid valve replacement (2 cases) and Kay procedure (1 case). Eight patients were recovered and discharged and 1 patient died from the bleeding of right atrial incision and low output syndrome. Twentyone patients received medical management and were followed up. One case was lost during followup. Conclusion Surgery or medical management should be based on the clinical characteristics of patients with severe TR after mitral valve surgery. It should be based on the features of tricuspid valve and the clinical experience of surgeon to perform tricuspid annuloplasty or replacement.
【Abstract】 Objective To investigate and evaluate the effectiveness of covering amputated raw surface with freetissue transplantation from damaged limbs. Methods Between August 2010 and June 2011, 5 cases of severe injury of lower extremities were treated, including 4 males and 1 female with an age range of 3 years and 8 months to 43 years. Of them, 3 cases suffered from traffic accident injury and 2 had machine injury. The disease duration was 2-9 hours. Among the 5 cases, 1 suffered from half pelvis destruction and traumatic amputation of hip joint, 1 from comminuted open fracture of proximal femur, and another 3 from thigh destruction with survival soft tissue of legs. All cases were treated with emergency operation of amputation. The raw surface of the residual stumps was 20 cm × 10 cm to 20 cm × 20 cm in size. Two lateral anterior thigh flaps and 3 posterior tibial artery flaps were harvested from the damaged limbs. The flap size ranged from 15 cm × 10 cm to 25 cm × 20 cm. The wounds were repaired with free tissue transplantation. Results Five transplanted tissue flaps were survival. Skin necrosis occurred in the wound edge at 7-10 days postoperatively and was cured after excision of necrotic tissue, dressing change or vacuumed drainage for 1-2 months. All wounds healed and the patients were followed up 1-3 months. No sinus tract or ulceration was observed. The appearance of stumps was satisfactory. Conclusion The effectiveness of repairing amputated raw surface with free tissue transplantation from amputated limbs is satisfactory. It is an effective procedure to repair the raw surface of amputated stumps.
Objectives To assess the efficacy and safety of standard trauma craniectomy (STC), compared with limited craniectomy (LC) for severe traumatic brain injury (sTBI) with refractory intracranial hypertension. Methods We searched the Cochrane Central Register of Controlled Trials-Central (The Cochrane Library Issue 3, 2008), MEDLINE (1966 to October 2008), EMbase (1984 to October 2008), CMB-disc (1979 to October 2006) and CNKI (1979 to October 2008) for completed studies, as well as clinical trial registries for ongoing studies and completed studies with unpublished data. The reference of included studies and relevant supplement or conference abstracts were handsearched. The search results were extracted, and then the quality of included studies was assessed using RevMan 5.0. Meta-analysis was conducted if the data was similar enough. Results Two randomized controlled trials (RCTs) involving 716 participants were identified. Compared with the LC group, the STC group had statistically significant, more favorable outcome on the basis of the Glasgow Outcome Scale, using measures such as mortality, efficiency, and survival, compared with those of LC group, which had statistic difference. The mean ICP fell more rapidly and to a lower level in the STC group than in the LC group. There was no statistically significant difference on the incidence of postoperative complications, including delayed hematoma, incision cerebrospinal fluid fistula, encephalomyelocele, traumatic epilepsy, and intracranial infection as well. Conclusion The efficacy of STC is superior to LC for severe TBI with refractory intracranial hypertension resulting from unilateral frontotemporoparietal contusion with or without intracerebral or subdural hematoma.
ObjectiveTo evaluate the therapic efficacy for severe acute pancreatitis (SAP) during different periods. MethodsAccording to internalized standard, 234 patients with SAP admitted to this hospital from January 1986 to October 2009 were included, which were divided into two stages based on the time of admitting to this hospital. The first stage named prior operation group was from January 1986 to August 1998 (n=117), the second stage named individual treatment group was from September 1998 to October 2009 (n=117). There was comparability in demography and clinic between two groups. The prior operation group primarily underwent laparotomy and medication, and the individual treatment group underwent multiple combined therapies. These indexes were compared between two groups: hospital stay, cure rate, and mortality; the incidences of pancreatic pseudocyst, pancreatic and peripancreatic abscess, pancreatic encephalopathy, cardiac insufficiency, acute renal failure (ARF), acute respiratory distress syndrome (ARDS), and shock. The efficacies for early treatment, ascites, biliary pancreatitis, and pancreatic and peripancreatic complications were compared two groups by stratified analysis. ResultsCompared with the prior operation group, the hospital stay was shorter (Plt;0.05), cure rate was higher (Plt;0.001), and mortality was lower in the individual treatment group (Plt;0.001). During the treatments, the incidences of pancreatic pseudocyst, pancreatic and peripancreatic abscess, pancreatic encephalopathy, cardiac insufficiency, ARF, ARDS, and shock in the individual treatment group were lower than those in the prior operation group (Plt;0.05). According to the stratified analysis, the efficacies for early treatment, ascites, biliary pancreatitis, and pancreatic and peripancreatic complications in the individual treatment group were better than those in the prior operation group (Plt;0.001). ConclusionIn recent years, the change of therapeutic mode significantly improves the treatment efficacy for SAP.
ObjectiveTo compare the efficacy and safety of Venus A-Valve and other overseas devices in transcatheter aortic valve replacement (TAVR) for patients with severe aortic stenosis (AS).MethodsWe retrospectively analyzed the baseline characteristics, procedural details, and postprocedural outcomes of severe AS patients who underwent TAVR with Venus A-Valve or overseas devices between April 2012 and January 2019 in West China Hospital of Sichuan University.ResultsA total of 342 AS patients undergoing TAVR were finally included, 238 with Venus A-Valve and the other 104 with overseas devices (43 with CoreValve, 33 with Lotus, 21 with SAPIEN XT, and 7 with SAPIEN 3). Baseline characteristics were comparable between the two groups, and the proportion of patients with bicuspid aortic valve was around 50% in both groups. After successful valve implantation, all patients’ hemodynamics were significantly improved, with the median of maximum velocity decreased to 2.30 m/s (inter-quartile range: 0.60 m/s) and 2.50 m/s (inter-quartile range: 0.62 m/s), respectively (P=0.003). Postprocedural 30-day and 1-year all cause mortalities were similar (30-day: 5.9% vs. 1.9%, P=0.086; 1-year: 8.4% vs. 5.8%, P=0.307), while low incidence of procedure-related complications and improved life quality were achieved in both groups.ConclusionTAVR with the domestic Venus A-Valve is feasible, safe, and can produce favorable outcomes for AS patients, and especially for Chinese TAVR population with a high prevalence of bicuspid aortic valve.
Objective To investigate the effects of ulinastatin on Treg/Th17 and immune status in patients with severe sepsis.Methods A total of 80 patients with severe sepsis, who were hospitalized in ICU during October 2011 to July 2012, were randomly divided into a routine group and a ulinastatin group. The patients in the ulinastatin group were intravenously administered 30mg ulinastatin three times per day for 5 days in addition to routine bundle treatment. The expression of Treg, Th17 and HLA-DR were detected on the first day in ICU and 5 days after treatment. 20 healthy individuals served as controls. Results Compared with the control group, the severe sepsis group had overexpression of Treg and Th17 ( P lt;0. 01) , higher ratio of Treg/Th17( P lt;0. 01) , and decreased HLA-DR expression of CD14 monocyte ( P lt; 0. 01) . In the severe sepsis patients, ulinastatin injection reduced the abnormal expression of Treg and Th17 ( P lt; 0. 01) , decreased the ratio of Treg/Th17( P lt; 0. 01) , and improved the expression of HLA-DR ( P lt; 0. 01) more effectively compared with the routine treatment. Ulinastatin also lowered 28-day mortality of the patients with sepsis, but the difference between the ulinastatin group and the routine group was not significant. Conclusions In severe sepsis patients, there were abnormal overexpression of Treg and Th17, imbalance of Treg/Th17, and underexpression of HLA-DR which imply an immune suppression. Ulinastatin can decrease the expression of Treg and Th17, inverses the ratio of Treg/Th17, and improve the expression of HLA-DR, so as to improve the prognosis of severe sepsis patients.
ObjectiveTo investigate the effect of PI3K/Akt/mTOR signaling pathway on liver injury induced by severe acute pancreatitis (SAP). MethodsForty healthy adult male Sprague-Dawley (SD) rats were randomly divided into 4 groups: Sham operation group (SO group), SAP group, PI3K inhibitor LY294002 group (LY294002 group), and mTOR kinase inhibitor rapamycin group (rapamycin group). The rat model with SAP was made by injection with 5% sodium deoxycholate through retrogradely bilio pancreatic duct. Serum levels of amylase (AMY), alanine aminotransferase (ALT), and aspartate transaminase (AST) were detected through the inferior vena at 6 h after modeling. Pathologic change of the liver was observed under the light microscope. TUNEL analysis was used to detect apoptotic index (AI) of the heptocyte. Expressions of Akt, phosphated-Akt (p-Akt), mTOR, phosphated-mTOR (p-mTOR) protein were evaluated by Western blot. Results①Compared with the SO group, the serum levels of AMY, ALT, AST, and the hepatocyte AI were significantly increased among the other three groups (P < 0.05). Compared with the SAP group, the serum levels of AMY, ALT, AST, and the hepatocyte AI were significantly decreased in the LY294002 group and rapamycin group (P < 0.05).②Compared with the SO group, the damages of the liver tissues were aggravated among the other three groups. The pathologies of the liver tissues were ameliorated in the LY294002 group and rapamycin group as compared with the SAP group.③Compared with the SO group, the levels of p-Akt/Akt, p-mTOR/mTOR were significantly increased among the other three groups (P < 0.05). Compared with the SAP group, the levels of p-Akt/Akt, p-mTOR/mTOR were significantly decreased in the LY294002 group (P < 0.05), but in the rapamycin group, only the p-mTOR/mTOR level was significantly decreased (P < 0.05). ConclusionThe activation of PI3K/Akt/mTOR signaling pathway might be one of the reasons for the liver injury induced by SAP and blocking this signaling pathway might be a potential target of preventing progress of SAP and alleviating liver injury induced by SAP.
ObjectiveTo explore effect of α-adrenoceptor on modulating water of lung in severe acute pancrea-titis (SAP) rat. MethodsThe SD rats were randomly divided into sham operation group (n=5) and SAP group,the SAP group was divided into subgroups of SAP-4 h (n=5) and SAP-24 h (n=5).SAP model was made by injecting taurocholate into bilopancreatic duct.The wet-to-dry ratio,alveolar fluid clearance (AFC),and AFC affected by α1-adrenoceptor inhibitor-prazosin and α2-adrenoceptor inhibitor-yohimbine separately or together were measured in the lungs.The α1-adrenoceptor and α2-adrenoceptor mRNA expressions in the lungs tissues were measured by real-time PCR. Results① The wet-to-dry ratios in the SAP-4 h group and SAP-24 h group were obviously decreased as compared with the sham operation group (P<0.05),which in the SAP-24 h group was significantly lower than that in the SAP-4 h group (P<0.05).② The AFCs in the SAP-4 h group and SAP-24 h group were obviously increased as compared with the sham operation group (P<0.05).The AFCs in the SAP with α1-adrenoceptor inhibitor-prazosin or α2-adrenocpetor inhibitor-yohimbine or prazosin combined with yohimbine were all obviously decreased as compared with the SAP group (P<0.05).③ The α1 adrenoceptor and α2 adrenoceptor mRNAs in the SAP-4 h group and SAP-24 h group were obviously increased as compared with the sham operation group (P<0.05). ConclusionAFC might be modulated by α-adrenoceptor in SAP rat.
