Myocardial Hematoma Documented by Transthoracic Echocardiography After Sequential Coronary Artery Stenting

We report the case of a patient who deteriorated suddenly while undergoing endoluminal coronary artery reconstruction with multiple stents to the left anterior descending coronary artery. With the aid of transthoracic echocardiography, a pericardial effusion was noted; however, dissection of the ventricular wall due to a large myocardial hematoma was also identified. Emergency exploration with evacuation of the pericardial blood with coronary artery bypass graft surgery was successfully accomplished. We discuss the possible factors that could have been associated with this unforeseen complication and the potential benefit of transthoracic echocardiography in early recognition.     

急性脑出血患者血浆N端脑钠肽前体、和肽素的检测及其临床意义

目的：探讨急性脑出血患者血浆 N 端脑钠肽前体（NT-proBNP）及和肽素与病情严重程度及脑出血量之间的关系。方法选取该院2011年12月至2013年6月期间诊断为急性脑出血患者109例（脑出血组）和同期体检的健康者32例（对照组）,对脑出血组患者和对照组健康者血浆 NT-proBNP、和肽素水平与格拉斯哥昏迷评分（GCS）进行比较。结果脑出血组血浆NT-proBNP 及和肽素水平明显高于对照组,随病情严重程度及出血量增加呈显著升高,差异有统计学意义（P ＜0．05）。血浆 NT-proBNP、和肽素水平与脑出血量呈正相关（r＝0．63,r＝0．58,P ＜0．01）,与 GCS 呈负相关（r＝－0．52,r＝－0．46,P ＜0．01）。结论血浆 NT-proBNP、和肽素水平和急性脑出血关系密切,能反映急性脑出血患者病情严重程度。     

高血压脑出血早期控制血压对血肿扩大的影响?

目的：研究早期控制血压对高血压性脑出血患者血肿扩大的影响。方法对96例急性期高血压脑出血患者随机分为强化降压组(48例)和标准降压组(48例),分别予以强化降压及标准降压。两组入院时及入院24 h 查头颅 CT 及神经功能评分,然后对两组头颅 CT 血肿体积大小及神经缺损功能评分进行对比分析。结果入院后24 h 强化降压组较标准降压组神经功能评分明显降低(P <0.05),入院后24 h 复查头部 CT 发现,强化降压组和标准降压组入院24 h 血肿体积及血肿扩大发生率比较,差异有统计学意义(P <0.05)。结论高血压脑出血早期控制血压可降低血肿扩大,减少神经功能缺损症状。     

Traumatic Lingual Hematoma Resulting in Bilateral Temporal Mandibular Joint Dislocations

Background

Lingual hematoma (LH) is a relatively uncommon entity seen after both medical and traumatic etiologies. Regardless of the cause, the feared complication is acute airway obstruction.

胸痛发作小于3 h的急性主动脉综合征与非ST段抬高型心肌梗死的差异化风险评估

目的研究在胸痛发作小于3 h的情况下,急性主动脉综合征(AAS)及非ST段抬高型心肌梗死(NSTEMI)的差异化风险评估。方法回顾性分析AAS患者69例,NSTEMI患者136例,对两组数据进行统计学分析,比较组间差异。利用单因素及多因素Logistic回归分析评估AAS及NSTEMI的差异化风险因素。比较各差异化风险因素的受试者工作特征曲线(ROC)下面积(AUC),分析各因素鉴别AAS及NSTEMI的价值,并确定部分差异风险因素的最佳截断值。结果多因素Logistic回归分析结果显示,相比于NSTEMI,D-二聚体(OR 8.872,95%CI 4.064~19.366)、血小板分布宽度(PDW)(OR 1.635,95%CI 1.253~2.133)、非结合胆红素(UCB)(OR 1.149,95%CI 1.003~1.317)、收缩压(SBP)(OR 1.025,95%CI 1.006~1.045)是AAS发生的高风险因素。ROC曲线分析显示,AUC_(D-二聚体)=0.944(95%CI 0.897~0.973),AUC_(PDW)=0.794(95%CI 0.724~0.853)。利用ROC曲线的约登指数确定D-二聚体及PDW从NSTEMI中鉴别AAS的最佳界值,D-二聚体的ROC曲线分界点为247.5μg/L,灵敏度为95.7%,特异度为83.8%;PDW的ROC曲线分界点为16.05%,灵敏度为58.8%,特异度为95.6%。结论D-二聚体、PDW、UCB、SBP是AAS及NSTEMI的差异化风险因素;当D-二聚体247.5μg/L时,可有效除外AAS;当PDW16.05%时,大概率发生AAS。     

Postbiopsy intramural hematoma of the duodenum in an adult with Noonan's syndrome

Intramural duodenal hematoma is a rare complication of endoscopic biopsy. It is usually seen in children with growth failure and in patients with bleeding disorders or who are anticoagulated. It is frequently associated with acute pancreatitis. We present a case of an adult patient with Noonan's syndrome who developed postbiopsy intraduodenal hematoma. Abdominal ultrasound and computed tomography scan established the diagnosis. Conservative treatment was successful. According to a brief review of the literature, patients with Noonan's syndrome may develop hematoma after sampling of the duodenum because they present all the main predisposing factors. Additionally, pulmonic valve stenosis may be another predisposing factor, but this may warrant further investigation.     

大鼠脑出血血肿周围组织内的环状出血现象及其病理机制探讨

目的对大鼠脑出血血肿周围组织内的环状出血现象及其病理机制进行初步研究。方法SD大鼠11只,随机分为模型组(5只),墨汁灌注组(4只),假手术对照组(2只)。动物模型采用大鼠尾状核自体动脉血注射制作脑出血模型,术后6 h灌注并浸泡固定,常规石蜡包埋、切片,HE染色。墨汁灌注组大鼠灌注固定后用印度墨汁右旋糖酐溶液灌注。结果模型组大鼠脑血肿周围组织内小血管周围环状出血灶均广泛存在。出血灶位于血管周围间隙内,围绕在小血管周围呈环状分布。环状出血灶内的血液来自于原发血肿。结论环状出血在血肿周围组织内广泛存在,是原发血肿内的血液沿血管周围间隙向外围扩展所致。     

Femoral artery catheterization complications: A study of 503 consecutive patients

This report describes a prospective randomized trial of 503 patients who underwent a cardiac catheterization or interventional procedure at a single institution. In an effort to study femoral complications postprocedure, we evaluated three methods of femoral artery hemostasis as well as 38 variables that were felt to potentially relate to local complications. Only a marginally significant relationship between the hemostasis method and complication rate was found. The factors that contributed to femoral artery complications were: restarting heparin postsheath removal, number of procedures done during one hospitalization, noncompliance of the patient with bedrest after the procedure, number of arterial punctures to initiate the procedure, and preprocedure treatment with corticosteroids.     

Traumatic Brain Injury in Patients Receiving Direct Oral Anticoagulants

BackgroundEmergency departments (EDs) are faced with a growing number of patients with traumatic brain injury (TBI) using direct oral anticoagulants (DOACs). However, there remains uncertainty about the bleeding risk, rate of hematoma expansion, and the efficacy of reversal strategies in these patients.ObjectiveThis study aims to identify the risk of traumatic hemorrhagic complications in patients with TBI using DOACs.MethodsIn this retrospective study we included patients with TBI. All TBI patients were using DOACs, attended one of the three EDs of our hospital between January 2016 and October 2019, and received a computed tomography (CT) scan of the brain. The primary outcome was any traumatic intracranial hemorrhage on CT. Secondary outcomes were the use of reversal agents, secondary neurological deterioration, a neurosurgical intervention within 30 days after the injury, length of stay (LOS), Glasgow Outcome Scale (GOS) at discharge, and mortality.ResultsOf the included patients (N = 316), 24 patients (7.6%, 95% confidence interval [CI] 4.2–9.8) presented with a traumatic intracranial hematoma (ICH). Seven patients (2.2%, 95% CI 0.6–3.8) received a reversal agent and 1 patient (0.3%, 95% CI ?0.3–0.9) underwent a neurosurgical intervention. Of the 24 patients with a traumatic ICH, progression of the lesion was seen in 6 patients (1.9%, 95% CI 0.4–3.4). The mean LOS was 6.5 days (95% CI 3.0–10.1) and the mean GOS at discharge was 4 (95% CI 3.6–4.6). Death occurred in 1 patient (0.3%, 95% CI ?0.3–0.9) suffering from an ICH.ConclusionBased on the present findings it can be postulated that TBI patients using DOACs have a low risk for ICH. Hematoma progression occurred, however, in a substantial number of patients. Considering the retrospective nature of the present study, future prospective trials are needed to confirm this finding.
