Abstract

OBJECTIVE:Temporary ventricular assist device (VAD) is a commonly used therapeutic option for cardiogenic shock. Patients requiring this treatment are often critical, and clinical outcomes remain unsatisfactory. This study evaluated the feasibility and efficacy of a sternotomy-avoiding technique for temporary VAD implantation to improve patient outcomes. METHODS:Between December 2012 and November 2018, seven patients underwent temporary VAD implantation by sternotomy-avoiding technique (SA group) and eight by median sternotomy technique (MS group). Pre- and intraoperative characteristics, postoperative 7-day hemodynamic parameters, 30-day mortality, and adverse events were compared between the groups. RESULTS:More than 50% of the patients were mechanically supported before temporary VAD implantation. Cardiopulmonary bypass time was significantly shorter in the SA than in the MS group (84 min vs 215 min; p = 0.011); surgical time tended to be shorter in the SA group (385 min vs 461 min; p = 0.064). Pump index, cardiac index, mixed venous oxygen saturation, and central venous pressure did not differ significantly during the first seven days of support. The 30-day incidence of any adverse event was not significantly different between the groups. No patients in the SA group needed re-exploration for surgical bleeding. Thirty-day all-cause mortality rates were 29% in the SA group and 0% in the MS group (p = 0.11). CONCLUSIONS:The sternotomy-avoiding and conventional techniques resulted in comparable short-term hemodynamic support. The sternotomy-avoiding technique was associated with a potential reduction in risk of re-exploration for bleeding. These results support the usefulness of the sternotomy-avoiding procedure for selected patients.

摘要

目的: 临时心室辅助装置 (VAD) 是心休克常用的治疗选择。需要这种治疗的患者通常是关键的,并且临床结果仍然不令人满意。本研究评估了胸骨切开术-避免技术用于临时VAD植入以改善患者预后的可行性和有效性。 方法: 在2012年12月至2018年11月期间,7例患者通过胸骨切开-避开技术 (SA组) 接受临时VAD植入,8例通过胸骨正中切开技术 (MS组)。比较两组患者术前和术中特征、术后7天血流动力学参数、30天死亡率和不良事件。 结果: 超过50% 的患者在临时VAD植入前得到机械支持。SA组体外循环时间明显短于MS组 (84 min vs 215 min; P   =   0.011); SA组手术时间有缩短趋势 (385 min vs 461 min; P   =   0.064)。在支持的前7天,泵指数、心脏指数、混合静脉血氧饱和度和中心静脉压没有显著差异。任何不良事件的30天发生率在各组之间没有显著差异。SA组中没有患者因手术出血需要再次探查。SA组和MS组的30天全因死亡率分别为29% 和0% (p = 0.11)。 结论: 避免胸骨切开术和传统技术可获得相当的短期血流动力学支持。避免胸骨切开术技术与再探查出血风险的潜在降低相关。这些结果支持了胸骨切开术-避免手术对于所选患者的有效性。

METHODS:OBJECTIVES:The aim was to evaluate the image quality and sensitivity to artifacts of compressed sensing (CS) acceleration technique, applied to 3D or breath-hold sequences in different clinical applications from brain to knee. METHODS:CS with an acceleration from 30 to 60% and conventional MRI sequences were performed in 10 different applications in 107 patients, leading to 120 comparisons. Readers were blinded to the technique for quantitative (contrast-to-noise ratio or functional measurements for cardiac cine) and qualitative (image quality, artifacts, diagnostic findings, and preference) image analyses. RESULTS:No statistically significant difference in image quality or artifacts was found for each sequence except for the cardiac cine CS for one of both readers and for the wrist 3D proton density (PD)-weighted CS sequence which showed less motion artifacts due to the reduced acquisition time. The contrast-to-noise ratio was lower for the elbow CS sequence but not statistically different in all other applications. Diagnostic findings were similar between conventional and CS sequence for all the comparisons except for four cases where motion artifacts corrupted either the conventional or the CS sequence. CONCLUSIONS:The evaluated CS sequences are ready to be used in clinical daily practice except for the elbow application which requires a lower acceleration. The CS factor should be tuned for each organ and sequence to obtain good image quality. It leads to 30% to 60% acceleration in the applications evaluated in this study which has a significant impact on clinical workflow. KEY POINTS:• Clinical implementation of compressed sensing (CS) reduced scan times of at least 30% with only minor penalty in image quality and no change in diagnostic findings. • The CS acceleration factor has to be tuned separately for each organ and sequence to guarantee similar image quality than conventional acquisition. • At least 30% and up to 60% acceleration is feasible in specific sequences in clinical routine.

METHODS:BACKGROUND:The main surgical techniques for spontaneous basal ganglia hemorrhage include stereotactic aspiration, endoscopic aspiration, and craniotomy. However, credible evidence is still needed to validate the effect of these techniques. OBJECTIVE:To explore the long-term outcomes of the three surgical techniques in the treatment of spontaneous basal ganglia hemorrhage. METHODS:Five hundred and sixteen patients with spontaneous basal ganglia hemorrhage who received stereotactic aspiration, endoscopic aspiration, or craniotomy were reviewed retrospectively. Six-month mortality and the modified Rankin Scale score were the primary and secondary outcomes, respectively. A multivariate logistic regression model was used to assess the effects of different surgical techniques on patient outcomes. RESULTS:For the entire cohort, the 6-month mortality in the endoscopic aspiration group was significantly lower than that in the stereotactic aspiration group (odds ratio (OR) 4.280, 95% CI 2.186 to 8.380); the 6-month mortality in the endoscopic aspiration group was lower than that in the craniotomy group, but the difference was not significant (OR=1.930, 95% CI 0.835 to 4.465). A further subgroup analysis was stratified by hematoma volume. The mortality in the endoscopic aspiration group was significantly lower than in the stereotactic aspiration group in the medium (≥40-<80 mL) (OR=2.438, 95% CI 1.101 to 5.402) and large hematoma subgroup (≥80 mL) (OR=66.532, 95% CI 6.345 to 697.675). Compared with the endoscopic aspiration group, a trend towards increased mortality was observed in the large hematoma subgroup of the craniotomy group (OR=8.721, 95% CI 0.933 to 81.551). CONCLUSION:Endoscopic aspiration can decrease the 6-month mortality of spontaneous basal ganglia hemorrhage, especially in patients with a hematoma volume ≥40 mL.

METHODS:OBJECTIVE:The primary purpose of this study was to evaluate the effectiveness of a three-dimensional (3D) software tool (smart planes) for displaying fetal brain planes, and the secondary purpose was to evaluate its accuracy in performing automatic measurements. MATERIAL AND METHODS:This prospective study included singleton fetuses with a gestational age (GA) greater than 18 weeks. Transabdominal two-dimensional ultrasound (2DUS) and 3D smart planes images were respectively used to obtain the basic planes of the fetal brain, with five parameters measured. The images, by either two-dimensional (2D) manual or 3D automatic operation, were reviewed by two experienced sonographers. The agreements between two measurements were analyzed. RESULTS:A total of 226 cases were included. The rates of successful detection by automatic display were as high as 80%. There was substantial agreement between the measurements of the biparietal diameter, head circumference and transcerebellar diameter, but poor agreement between the measurements of cisterna magna and lateral ventricle width. CONCLUSIONS:Smart Planes might be valuable for the rapid evaluation of fetal brain, because it simplifies the evaluation process. However, the technology requires improvement. In addition, this technology cannot replace the conventional manual US scans; it can only be used as an additional approach.
