RESUMO
@#Objective To compare clinical outcomes between the performed titanium locking plate and nickel-titanium memory alloy embracing fixator for the treatment of multiple rib fractures, and to select a better internal fixator for multiple rib fractures. Methods A total of 206 consecutive patients with multiple rib fractures were admitted to Department of Cardiothoracic Surgery in Beijing Luhe Hospital of Capital Medical University from October 2011 to September 2016. According to different treatment strategies, the patients were divided into 2 groups: a performed titanium locking plate group (a titanium plate group, n=105) and a nickel-titanium memory alloy embracing fixator group (an embracing fixator group, n=101). There were 82 males and 23 females with a mean age of 46.5±9.7 years ranging from 23 to 65 years in the titanium plate group, and 83 males and 18 females with a mean age of 44.7±10.3 years ranging from 19 to 63 years in the embracing fixator group. The preoperative data, curative outcomes, visual analogue scale (VAS) and postoperative complications were compared between the two groups. Results There was no statistical difference in the preoperative data between the two groups, and all patients successfully completed the operation. Compared with the embracing fixator group, the incision length and operation time were shorter, intraoperative bleeding and VAS score were less, and curative outcome was better in the titanium plate group. Conclusion The performed titanium locking plate has a great advantage in the clinic, which can be preferred.
RESUMO
Background: Long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI) remain uncertain. Objective: To investigate long-term outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in patients with ST-segment elevation myocardial infarction (STEMI). Methods: We performed search of MEDLINE, EMBASE, the Cochrane library, and ISI Web of Science (until February 2013) for randomized trials comparing more than 12-month efficacy or safety of DES with BMS in patients with STEMI. Pooled estimate was presented with risk ratio (RR) and its 95% confidence interval (CI) using random-effects model. Results: Ten trials with 7,592 participants with STEMI were included. The overall results showed that there was no significant difference in the incidence of all-cause death and definite/probable stent thrombosis between DES and BMS at long-term follow-up. Patients receiving DES implantation appeared to have a lower 1-year incidence of recurrent myocardial infarction than those receiving BMS (RR = 0.75, 95% CI 0.56 to 1.00, p= 0.05). Moreover, the risk of target vessel revascularization (TVR) after receiving DES was consistently lowered during long-term observation (all p< 0.01). In subgroup analysis, the use of everolimus-eluting stents (EES) was associated with reduced risk of stent thrombosis in STEMI patients (RR = 0.37, p=0.02). Conclusions: DES did not increase the risk of stent thrombosis in patients with STEMI compared with BMS. Moreover, the use of DES did lower long-term risk of repeat revascularization and might decrease the occurrence of reinfarction. .
Fundamento: Os resultados a longo prazo dos stents farmacológicos (SF) contra stents convencionais (SC) em pacientes com infarto do miocárdio com elevação do segmento ST (IMEST) permanecem incertos. Objetivo: Investigar os resultados a longo prazo dos stents farmacológicos (SF) contra stents convencionais (SC) em pacientes com infarto do miocárdio com elevação do segmento ST (IMEST) . Métodos: Foi realizada pesquisa de dados nas bases de dados MEDLINE, EMBASE, na Cochrane Library, e na ISI Web of Science (até fevereiro de 2013) para estudos clínicos aleatórios que comparam a eficácia durante mais de 12 meses ou a segurança do SF com SC em pacientes com IMEST. Foi apresentada uma estimativa agrupada com risco relativo (RR) e seu intervalo de confiança de 95 % (IC), utilizando modelo de efeitos aleatórios. Resultados: Dez estudos com 7.592 participantes com IMEST foram incluídos. Os resultados gerais mostraram que não houve diferença significativa na incidência de morte por todas as causas e trombose de stent definida/provável entre SF e SC em seguimento de longo prazo. Os pacientes que receberam implante de SF pareciam ter uma incidência de infarto do miocárdio recorrente inferior a1 ano que aqueles que receberam SC (RR = 0,75, 95% CI 0,56-1,00, p = 0,05). Além disso, o risco de revascularização do vaso alvo (RVA) depois de receber o SF diminui consistentemente durante a observação a longo prazo (todos p <0,01). Na análise de subgrupo, o uso de stents com eluição de everolimus (EEE) foi associado a um risco reduzido de trombose de stent em pacientes IMEST (RR = 0,37, p = 0,02). Conclusões: SF não aumentou o risco de trombose de stent em pacientes com IMEST em comparação com SC. Além disso, o uso de SF fez baixar o risco de longo prazo de repetição ...
