目的 探究3D打印数字化塑形聚醚醚酮（PEEK）材料在颅骨修补个体化重建中的应用效果。方法 收集我院90例行颅骨修补个体化重建手术患者（2019年1月—2021年1月）,按术中应用的颅骨修补材料不同分成PEEK组（n=30）、钛网（TM）组（n=60）。2组均行颅骨修补个体化重建术。对比2组围术期指标、手术前后简易智力状态量表（MMSE）、格拉斯哥预后评分（GOS）、颅骨缺损塑形满意度、并发症发生率、材料生物相容性及患者主观感觉情况。结果 与TM组相比,PEEK组住院时长更短、治疗费用更高（P<0.05）;与术前相比,2组术后、6个月、12个月、18个月MMSE、GOS评分均升高,其中PEEK组升高幅度比TM组更为多（P<0.05）;PEEK组总满意度为93.33%,与TM组的80.00%比较差异无统计学意义（P>0.05）;PEEK组并发症总发生率为6.67%,与TM组的15.00%比较差异无统计学意义（P>0.05）;PEEK组材料生物相容性及患者主观感觉情况与TM组比较差异无统计学意义（P>0.05）。结论 3D打印数字化塑形在颅骨修补个体化重建中,应用PEEK材料治疗费用更高,但可有效减少并发症,缩短住院时长,改善认知功能及预后,提升颅骨缺损塑形满意度,且材料生物相容性高,震动感和冷热感觉体验少。

目的 探讨腹主动脉瘤腔内修复术后瘤体直径和瘤体体积的转归以及与术后内漏的关系。方法 回顾性分析2015年—2020年在我院行腹主动脉瘤腔内修复术的83例患者的临床及影像学资料。测量术前和术后各随访时间点瘤体最大直径及体积。CT评价术后内漏发生情况。定义瘤体（直径/体积）扩张/回缩及瘤体（直径/体积）稳定。以术前瘤体最大直径大小和术后内漏发生情况将患者分组,比较组间各随访时点的瘤体直径和体积转归情况。结果 患者术后平均随访时间24（10~62）个月。以瘤体直径<50 mm及≥50 mm分组,术后各随访时间点2组间瘤体体积及瘤体直径比较均无统计学差异。以术后有无内漏分组,术后各随访时间点组间比较瘤体体积变化比较差异均有统计学意义（P<0.05）,但瘤体直径变化组间比较差异均无统计学意义。结论 主动脉瘤瘤体体积与直径变化并不存在一致性,监测瘤体体积可以发现那些直径变化不明显的瘤体变化;腹主动脉瘤腔内修复术后内漏可能是导致瘤体增大的因素之一。

Objective To evaluate the outcome of aneurysm diameter and volume,and the role of endoleak after endovascular aneurysm repair of abdominal aortic aneurysm．Methods The clinical and imaging data from 83 patients who underwent endovascular repair of abdominal aortic aneurysm in our hospital from 2015 to 2020 were retrospectively analyzed．The maximum aneurysm diameter and volume were measured at the preoperative and postoperative follow-up time points．CT was used to evaluate the incidence of postoperative leakage．The aneurysm（diameter/volume）expansion/shrinkage and aneurysm（diameter/volume）stability were defined．Patients were divided into different groups according to the maximum preoperative aneurysm diameter and the incidence of postoperative endoleak,and the outcomes of aneurysm diameter and volume were compared at established follow-up points．Results The mean follow-up time was 24（10-62）months．There were no statistically significant differences in postoperative aneurysm volume and diameter at follow-up points between the patients with aneurysm diameter <50 mm and patients with aneurysm≥50 mm．There were statistically significant differences in postoperative aneurysm volume between the patients with postoperative endoleak and patients without postoperative endoleak（P<0.05）．However,there were no statistically significant differences in postoperative diameter between the two groups．Conclusions The changes of aneurysm volume and diameter were not closely related,and the detection of aneurysm volume can help to find the aneurysm changes with no obvious diameter changes．The postoperative endoleak after endovascular aneurysm repair may be one of the factors leading to aneurysm enlargement．

目的 探究超声检查对于甲状腺囊性结节随访中的作用和临床价值,探讨其临床应用意义。方法 以2018年1月—2019年1月在本院就诊,经过临床金标准诊断为甲状腺囊实性结节的83名患者作为研究对象,采用历史性队列研究方法对患者进行为期18个月的随访观察,对患者在随访期内,使用超声检查所得知的甲状腺囊实性结节的大小、形态、边界、内部回声、钙化及血流信号等特征进行记录,并与患者初次就诊时的记录进行对比分析。结果 根据随访记录得知,83例患有甲状腺囊实性结节的患者当中,75例患者在随访后发现具有甲状腺恶性结节症,其余8例患者不具有甲状腺恶性结节特征。随访后83例患者的甲状腺囊实性结节均呈现好转,主要表现为:甲状腺囊实性结节出现不同程度的吸收;结节体积减小,个数无变化;结节吸收后在超声下显示在同一部位的结节表现为低或极低回声结节;囊性液体成分明显减少,部分原结节较小的患者,囊性成分出现消失。根据对随访前后患者甲状腺囊实性结节的平均体积对比有统计学差异(P<0.05),随访后的结节半径明显小于随访前。甲状腺囊实性结节体积有效缩小率为68%～88%。结论 通过对甲状腺囊实性结节定期进行超声复查可以实现对甲状腺结节的动态观察,有助于对患者的病情进行掌握,且由于甲状腺囊实性结节患者在后期结节吸收过程中常常出现恶性结节特征。通过使用超声检查对患者进行长期随访不仅可起到早期诊断甲状腺恶性肿瘤的意义,还可以避免,因过度诊断为甲状腺恶性结节,而使用细胞穿刺检查等有创检查对患者造成的不便。
