Traditionally, the manner of death in most hospital autopsy cases is natural, in which death is due to the natural course of disease or reasonably anticipated outcomes of medical interventions. Some cases fall into a potential gray zone between natural and accident, including rare or unanticipated outcomes of medical interventions. We present a case of a patient postcoronary artery bypass graft. Autopsy revealed the proximal anastomosis of the aorta‐to‐first‐diagonal‐coronary‐artery‐to‐second‐obtuse‐marginal‐artery graft was detached from the aorta. A broken suture was present at the disconnected anastomosis, with intact knots but was broken along its length. In‐hospital mortality rates of CABG range from 1% to 3%, with several autopsy studies identifying surgical complications as the cause of death in one‐third of perioperative deaths. No publications were found that described suture rupture as directly relating to the cause of death. This case report describes a previously unreported complication of coronary artery bypass grafting. 相似文献

Previous studies on cytoskeletal changes of in vitro and in vivo animal models of ischemic myocardium have suggested the possibility of using alterations in cytoskeleton proteins as an early marker for the post-mortem diagnosis of myocardial ischemia in cases of sudden death due to coronary artery disease (CAD). In the present study, using the technique of ABC-immunohistochemistry, we examine the changes of three cytoskeletal proteins: vinculin, desmin and α-actinin in human myocardial samples taken from 14 cases of CAD sudden death and 13 cases of non-CAD death. Results of these examinations are compared with immunohistochemical changes of myoglobin and histochemical staining of hematoxylin and eosin and phosphotungstic acid, and Masson trichrome. Patchy and extensive loss of the three cytoskeletal proteins was demonstrated in the myocardium of victims who died 1 h or later following the onset of symptoms of ischemic myocardium. The pattern of cytoskeleton change is equivocal in the cases of CAD who died less than 1 h after the onset of symptoms and of the cases of non-CAD. In these cases, no significant histological change was observed. With less non-specific background changes and stronger positive staining, immunohistochemical staining of the three cytoskeletal proteins is more reliable than myoglobin, which has attracted the attention of many pathologists searching for anatomic evidence of ischemic myocardium in coronary artery disease. 相似文献

Frontal sinuses (FSs) have been studied in radiology, anthropology, and forensic anthropology. This study aimed to determine whether it was possible to predict the age and sex of an individual using FS volume. Sixty‐nine anonymized CT scans were imported to MIMICS 10.01® software (Materialise N.V.), and each FS volume was calculated in mm3. There was an absence of significant difference between right and left FS volume (p = 0.173) and an absence of correlation between age and FS volume (Pearson's test; p = 0.705). Sexual dimorphism was significantly different (p = 0.001). However, the most discriminant datum for determining sex was found to be the total FS volume (sum of an individual's right and left FS volumes) with linear discriminant Fisher's function coefficients of ?2.759 for the male group and ?1.275 for the female group. With this model, 72.5% of our sample was correctly classified according to sex. 相似文献

The high-pressure water jet unit is a generator of frequent burst of water jets. The water jet reaches very high speeds and is able to cause wounds similar to those of high-velocity projectiles. In the presented case, unusual fatal injuries sustained by water jet are presented. Operating with the unit, an untrained worker accidentally activated a high-pressure water jet unit, and the extremely high pressure of water liberated the jet unit from his hand and whirled it around him. A jet stream of water ran across his body and caused fatal penetrating injuries in the femoral region. The edges of the wound were mainly sharp with contusion rings on the skin beyond the edges. Exploring the inside of the canals during the autopsy, the left femoral artery and vein were found to be completely transected. The resemblance to a firearm entry wound and the severity of the internal injury make it a noteworthy entity. 相似文献

After strangulation, cervical arterial injuries (CAI) are uncommon. We report three unusual cases where strangulation induced immediate stroke. CAI were examined using brain CT scan and Doppler ultrasonography in the three cases and then by autopsy in one of the victims. One of the two victims who survived the attempted strangulation had a unilateral carotid dissection, whereas in the other victim, no arterial dissection or thrombosis was observed. As regards the deceased victim, the autopsy confirmed the bilateral dissection showed on CT scan and Doppler ultrasonic examination and revealed that both carotid arteries were dilated up to two times the normal diameter. Microscopic examination showed a major bilateral hemorrhagic dissection of the media with obliterating fibrous endarteritis lesions associated with inflammatory damage. CT scan with arteriography does not demonstrate all the different types of arterial injury, particularly atheromatous embolism, direct compression, or prolonged spasm. Thus, traditional autopsy remains an essential forensic tool after strangulation to show the type of CAI. 相似文献

目的观察化瘀散结法治疗子宫肌瘤患者行子宫动脉栓塞术(uterine fibroid artery embolization,UFAE)后并发症的近期临床疗效。方法将60例瘀阻胞宫证子宫肌瘤患者随机分为治疗组和对照组各30例,两组均采用Sldinger技术完成UFAE治疗。治疗组在术后3个月服用活血化瘀、散结消癥类中药,对照组酌情予对症治疗。两组患者均术后随访6个月,详细观察并记录患者治疗前后月经变化,栓塞综合征出现的时间、程度、缓解方法及消失时间。结果两组术后均未发现闭经;对照组出现1例轻度泌尿生殖系统感染,治疗组无泌尿生殖系统感染;治疗组发生盆腔疼痛的病例数显著低于对照组;治疗组盆腔疼痛评分、持续时间和阴道不规则流血持续时间显著低于对照组(P<0.05)。结论化瘀散结法治疗UFAE并发症具有明显优势,不良反应少,临床具有较好的应用前景。 相似文献
