Reconstruction and Quantitative Evaluation of Blunt Injury Cases by Finite Element Method / 法医学杂志

OBJECTIVES@#To reconstruct the cases of acceleration craniocerebral injury caused by blunt in forensic cases by finite element method (FEM), and to study the biomechanical mechanism and quantitative evaluation method of blunt craniocerebral injury.@*METHODS@#Based on the established and validated finite element head model of Chinese people, the finite element model of common injury tool was established with reference to practical cases in the forensic identification, and the blunt craniocerebral injury cases were reconstructed by simulation software. The cases were evaluated quantitatively by analyzing the biomechanical parameters such as intracranial pressure, von Mises stress and the maximum principal strain of brain tissue.@*RESULTS@#In case 1, when the left temporal parietal was hit with a round wooden stick for the first time, the maximum intracranial pressure was 359 kPa; the maximum von Mises stress of brain tissue was 3.03 kPa at the left temporal parietal; the maximum principal strain of brain tissue was 0.016 at the left temporal parietal. When the right temporal was hit with a square wooden stick for the second time, the maximum intracranial pressure was 890 kPa; the maximum von Mises stress of brain tissue was 14.79 kPa at the bottom of right temporal lobe; the maximum principal strain of brain tissue was 0.103 at the bottom of the right temporal lobe. The linear fractures occurred at the right temporal parietal skull and the right middle cranial fossa. In case 2, when the forehead and left temporal parietal were hit with a round wooden stick, the maximum intracranial pressure was 370 kPa and 1 241 kPa respectively, the maximum von Mises stress of brain tissue was 3.66 kPa and 26.73 kPa respectively at the frontal lobe and left temporal parietal lobe, and the maximum principal strain of brain tissue was 0.021 and 0.116 respectively at the frontal lobe and left temporal parietal lobe. The linear fracture occurred at the left posterior skull of the coronary suture. The damage evaluation indicators of the simulation results of the two cases exceeded their damage threshold, and the predicted craniocerebral injury sites and fractures were basically consistent with the results of the autopsy.@*CONCLUSIONS@#The FEM can quantitatively evaluate the degree of blunt craniocerebral injury. The FEM combined with traditional method will become a powerful tool in forensic craniocerebral injury identification and will also become an effective means to realize the visualization of forensic evidence in court.

Characteristics and Forensic Identification of Blunt Vertebral Artery Injury / 法医学杂志

Blunt vertebral artery injury occurs frequently in forensic practice. However, injuries of the vertebral artery are easily ignored or overlooked because of its relatively deep location. Through literatures review, this paper finds that the manners of blunt vertebral artery injury are varied and one or more injury mechanisms may be involved simultaneously. Patients often undergo immediate or delayed cerebral apoplexy as well as compression and injury of surrounding structures, due to direct injury or secondary aneurysm or dissection, resulting in disability or death. Diseases such as, vertebral atherosclerosis and dysplasia can increase the disability and death risk and the difficulty of forensic identification. In forensic identification, the details of the case should be considered. For cases of suspected vertebral artery injury, in addition to routine examination of intracranial segment, attention should be paid to the examination of extracranial segment. If conditions permit, angiography can be used prior to or during the autopsy to improve the identification efficiency and accuracy of opinions.

Complete transection of third part of duodenum following blunt injury abdomen: a rare case report

Blunt injury abdomen (BIA) is an ever-increasing problem. Isolated injury to duodenum following BIA is rare (1-4%). It can be a challenge to the surgeon and failure to manage it properly can lead on to devastating results. Blunt duodenal injury can occur in isolation or with pancreatic injury. We report a case of an isolated transection of third part of the duodenum following BIA. Initial clinical changes in isolated duodenal injury may be subtle before life-threatening peritonitis develops. High index of suspicion, knowledge of mechanism of injury, physical examination and proper imaging techniques are the key in early detection of duodenal injury.

Comprehensive study of blunt injury abdomen in single center

Background: Blunt injury abdomen is the leading cause of morbidity and mortality in all age groups. Blunt trauma differs from penetrating trauma as different organs are characteristically injured by compression from blunt straining. Focused assessment with sonography for trauma (FAST) and computed tomography (CT) abdomen are very beneficial to detect those patients with minimal and clinically undetectable signs of abdominal injury. Objective of the study was to evaluate the incidence of blunt injury abdomen, mode of injury, organs involved in patients.Methods: A retrospective study was done on blunt injury abdomen. 48 patients were enrolled in this study.Results: Out of 48, 35 (72.9%) male patients more commonly encountered blunt injury to the abdomen. 28 (58.3%) was the highest incidence for age group 21-40 years. The most common mode of injury was road traffic accidents 36 (75.0%). Grade III splenic injuries were encountered in majority 19 cases and 13 cases involved laceration of parenchyma >3 cm depth and 6 cases were subcapsular hematoma (>50%). Spleen was the most common injured organ accounting for 25 (52.0%) and second most common injury was Ileal perforation 6 (12.5%), liver injury 6 (12.5%) of the cases.Conclusions: Blunt injury abdomen mainly affected male and the younger population between the age group 21-40 years. The most common mode of injury is road traffic accidents. In this study the spleen was found to be the most common organ injured in blunt injury abdomen.

Study of the Various Factors which Influence the Outcome of Patients with Blunt Injury Chest

Introduction: Injury is the most common cause of death among people aged 1–34 years. The most common cause of injury is a road traffic accident and the majority is confined to the thoracic cage. These consist of rib fractures with underlying pulmonary contusion. When ignored, underestimated or inadequately treated chest injuries may cause the death of a patient during surgical intervention for seemingly more pressing intracranial or abdominal hemorrhage. Aim: This study aims to study the outcome of blunt injury chest patients in emergency and various modalities of treatment to identify possible risk factors for mortality. Materials and Methods: A prospective review of all cases of trauma with blunt chest injuries evaluated with X-ray or computed tomography scan. The cases were examined for age, type of injuries, presence or absence of rib fractures, hemothorax, or pneumothorax. Results: There were 50 patients included in this study. All had rib fractures and hemo/pneumothorax, 3 had lung contusion, 19 patients had associated injuries, 1 patient underwent emergency thoracotomy, 3 patients were kept on ventilator support, and 3 expired. Conclusion: Close attention to improving gas exchange and early management of hemo/pneumothorax might improve outcomes in blunt injury chest.

Efficacy of new scoring system for diagnosis of abdominal injury after blunt abdominal trauma in patients referred to emergency department / 中华创伤杂志(英文版)

PURPOSE@#The blunt abdominal trauma (BAT) is a common emergency and is significantly associated with morbidity and mortality. Our study was conducted to achieve the goal that a new scoring system could be used for the BAT patients.@*METHODS@#The statistical population of this study was 1000 patients with BAT referred to emergency department of Imam Hossein Hospital, Tehran, Iran. Sampling was carried out in a convenience non-random manner and continued to reach the required sample size. All the patients with BAT due to road traffic accidents, falls, and other direct blunt traumas such as punctures and kickbacks were included in the study. Exclusion criteria were after 3 months of pregnancy, under the age of 18, warfarin taking, no reliable medical history providing and penetrating trauma. The study questionnaire was based on BAT scoring system. The data were analyzed by SPSS V20 software. The receiver operating characteristic curve was used to analyze the effectiveness of the new scoring system in predicting the BAT patients' outcome.@*RESULTS@#The mean age of the patients (n = 1000) was (35.79 ± 13.09) years. The mean score of patients was (6.29 ± 5.80). Based on this scoring system, the patients were divided into three categories. The first group was patients at low risk with score of less than 8, the second group was patients at moderate risk with score of 8-12 and the third group was patients at high risk with score of 12-24. The score of 661 (66.1%) patients were low, 109 (10.9%) were moderate and 230 (23%) had a high score. The association between hip fracture and abdominal tenderness with abdominal injury was significant (p < 0.001). Cronbach's alpha was 0.76 showing the reliability of this questionnaire to predict the future of patients.@*CONCLUSIONS@#The study tool has a sensitivity to predict the BAT patients' outcome, and has a proper specificity that can be used to reduce the use of harmful modalities such as computed tomography scan.

Assessment of the Forensic Autopsies due to Blunt Injury Abdomen among the Patients Admitted to the Hospital - A Retrospective Study

Introduction: Blunt injury in the abdomen is seen morecommonly because of rapid industrialization and increasednumber of vehicles ultimately leading to more numberof accidents. It can occur as a result of fall from height,assault with blunt objects, sports injuries, and bomb blasts.In majority of the cases, blunt injury was the cause of death.In criminal violence, blunt injuries lead to death and more offorensic importance. The aim of the present study was to makea pattern of blunt abdominal injuries, which were fatal andresulted in death.Material and methods: A total of 160 cases of deaths fromblunt abdominal trauma from 1st July 2011 to 30th June 2013were included in the study. Demographic details about age,gender, occupation brief facts of the cases collected from theinquest report were entered. Patterns of death and types ofinjuries were studied and the data was collected through a predesigned format.Results: The most common age group affected with bluntabdominal injuries was 20-40 years followed by above 40years and below 20 years. The main cause of injury was foundto be due to road accidents. The most common organ involvedin blunt injury of abdomen was liver followed by intestineand spleen. The mechanism of death was found to be due tohemorrhage.Conclusion: Injury to abdomen is considered to be the mostcommon reason for morbidity and mortality among thegeneral population.

Retrospective study on the influencing factors of lacrimal canalicular rupture repair / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM:To analyze and compare the influence of different injury sites and injury types on surgical repair of canalicular laceration.<p>METHODS: A retrospective study was conducted on 87 cases(87 eyes)of traumatic canalicular laceration from January 2016 to August 2017, who were treated with silicone lacrimal drainage tube implantation. Lacrimal irrigation were performed 3mo and 6mo after surgery, and their respective operation results were evaluated. 3mo after surgery, lacrimal drainage tube were removed. Statisical analysis was proceeded on injury types, distances as well as the success rate of lacrimal passage irrigation.<p>RESULTS: Among the 87 cases of canalicular laceration, 29 eyes(33%)were in the PCL(proximal canalicular laceration)group, 41 eyes(47%)were in the MCL(medial canalicular laceration)group, and 17 eyes(20%)were in the DCL(distal canalicular laceration)group. There were 22 eyes(25%)of lacrimal canaliculi fracture caused by sharp instrument injury, including 18 eyes in the PCL group, 2 eyes in the MCL group and 2 eyes in the DCL group. There were 65 eyes(75%)of lacrimal canaliculi fracture caused by blunt trauma or collision, including 11 eyes in the PCL group, 39 eyes in the MCL group and 15 eyes in the DCL group. Six months after surgery, 72 eyes of lacrimal passage irrigation were successful, including 20 eyes in the PCL group, 36 eyes in the MCL group, and 16 eyes in the DCL group. The success rate of postoperative anatomic reduction in the three groups was 69%、88%、94%, respectively(<i>P</i>=0.047). There were 19 eyes of acute injury and 53 eyes of blunt injury with successful lacrimal duct irrigation respectively. The success rate of anatomical reduction was 86%、82%(<i>P</i>=0.605), respectively.<p>CONCLUSION: The canalicular laceration closed to lacrimal punctum is more vulnerable to cutting injury, while the canalicular laceration, which is near the lacrimal sac or between the lacrimal sac and center part of lacrimal punctum, can be more likely caused by lacerated wound. The success rate after operation is higher for patients with distal or medial canalicular laceration, and lower for those who with blunt wound location near the lacrimal punctum.

A Prospective Study Of Laryngotracheal Trauma And It‘S Management

BACKGROUND: Traumatic injuries of the larynx are diverse, uncommon, and potentially life threatening. Laryngotracheal trauma can be oadly divided into External trauma , which can be blunt or penetrating trauma , and internal trauma , which can be iatrogenic , thermal , caustic and foreign body injuries .external trauma which can be blunt trauma caused by motor vehicle accidents , suicidal or homicidal strangulation and penetrating trauma caused by suicidal or homicidal cut throat injuries . Iatrogenic injuries are most common cause of internal trauma . If not adequately treated these injuries lead to significant morbidity such as dysphonia , airway stenosis , aspiration and sometimes may lead to death . Laryngotracheal trauma is often associated with concomitant cervical or intracranial trauma or with multisystem poly trauma . External laryngeal trauma is rare. It has a population incidence of 1 in 137,000 in adults and accounts for 0.5% of trauma admissions in children. Incidence of postintubation laryngotracheal stenosis requiring surgical correction is 1 in 204,000 in adults and 4.9 in 100,000 in children.Laryngeal webs , intubation granulomas , laryngeal injuries while intubation , inhalational and ingestion injuries are very rare in incidence 1 . MATERIALS AND METHODS: 20 patients who presented with external and internal laryngotracheal trauma to casualty department in Government general hospital, Kakinada, Andhra Pradesh state , during the period between June 2015 to September 2017. A detailed history was taken with emphasis on trauma.Clinical features were noted and patients were appropriately investigated . RESULTS: The age of patients in present study varied from 12-70 years . Majority of patients are present in 26-40 years age group (55%) . Among the 20 cases in our study 13 cases were males (65%) and 7 cases were females (35%). In our study of 20 patients 14 patients sustained injuries due to external trauma(70%) and 6 patients presented with internal trauma of larynx(30%) due to prolonged intubation . In our study 6 of the 20 patients presented with laryngeal stenosis due to prolonged intubation among them 3 patients presented with subglottic stenosis 2 with glottic stenosis and 1 tracheal stenosis. Amongst them 9 of 14 patients were due to penetrating neck injuries(64.3%) and 5 of 14 are due to blunt neck trauma (35.7%) . 7 of 9 patients knife infected wounds and 2 due to motor vehicle accident. 2 of 5 patients in blunt trauma are due to hanging 2 are due to strangulation and one is due to bullgore injury. Most commonly presented with pain (70%) , dyspnoea (50%) , hoarseness (45%) . stridor was present mostly in laryngeal stenosis patients. The present study 15 of 20 patients airway was initially managed with the help of tracheostomy in 3 of 20 patients with intubation and 2 patients were under observation. There was a recurrence in one case of subglottic stenosis and endoscopic laser exicision was done again .In further followup there was no recurrence. CONCLUSION: In conclusion, we believe that the management of injuries to the larynx and trachea can be individualized based on the clinical presentation and mechanism of injury. Early diagnosis and stratification of treatment based on the initial history, physical findings has improved outcomes. Our goal remains preservation of life with restoration of a normal airway and voice. Patients with blunt injuries can often be managed conservatively with close monitoring in the intensive care unit. Penetrating injuries will often have associated injuries or airway compromise that will mandate operative exploration.

Pancreatic Compression during Lymph Node Dissection in Laparoscopic Gastrectomy: Possible Cause of Pancreatic Leakage

PURPOSE: Postoperative pancreatic fistula is a serious and fatal complication of gastrectomy for gastric cancer. Blunt trauma to the parenchyma of the pancreas can result from an assistant's forceps compressing and retracting the pancreas, which in turn may result in pancreatic juice leakage. However, no published studies have focused on blunt trauma to the pancreas during laparoscopic surgery. Our aim was to investigate the relationship between compression of the pancreas and pancreatic juice leakage in a swine model. MATERIALS AND METHODS: Three female pigs were used in this study. The pancreas was gently compressed dorsally for 15 minutes laparoscopically with gauze grasped with forceps. Pancreatic juice leakage was visualized by fluorescence imaging after topical administration of chymotrypsin-activatable fluorophore in real time. Amylase concentrations in ascites collected at specified times was measured. In addition, pancreatic tissue was fixed with formalin, and the histology of the compressed sites was evaluated. RESULTS: Fluorescence imaging enabled visualization of pancreatic juice leaking into ascites around the pancreas. Median concentrations of pancreatic amylase in ascites increased from 46 U/L preoperatively to 12,509 U/L 4 hours after compression. Histological examination of tissues obtained 4 hours after compression revealed necrotic pancreatic acinar cells extending from the surface to deep within the pancreas and infiltration of inflammatory cells. CONCLUSIONS: Pancreatic compression by the assistant's forceps can contribute to pancreatic juice leakage. These findings will help to improve the procedure for lymph node dissection around the pancreas during laparoscopic gastrectomy.

Bile Duct Stricture and Intrahepatic Cystic Formation after Abdominal Injury due to Child Abuse: A Case Report

A 6-year-old male who lived with a mother in a single-parent family was referred to the emergency room with multiple traumas. There was no specific finding on CT scan of the other hospital performed 55 days before admission. However, CT scan at the time of admission showed common bile duct (CBD) stenosis, proximal biliary dilatation and bile lake formation at the segment II and III. Endoscopic retrograde biliary drainage was performed, but the tube had slipped off spontaneously 36 days later, and follow-up CT scan showed aggravated proximal biliary dilatation above the stricture site. He underwent excision of the CBD including the stricture site, and the bile duct was reconstructed with Roux-en-Y hepaticojejunostomy. Pathologic report of the resected specimen revealed that the evidence of trauma as a cause of bile duct stricture. While non-iatrogenic extrahepatic biliary trauma is uncommon, a level of suspicion is necessary to identify injuries to the extrahepatic bile duct. The role of the physicians who treat the abused children should encompass being suspicious for potential abdominal injury as well as identifying visible injuries.

Initial D-dimer level as early prognostic tool in blunt trauma patients without significant brain injury

OBJECTIVE: The purpose of this study was to evaluate whether or not the d-dimer level indicating hyperfibrinolysis could be a predictor of early poor outcome (massive transfusion, death within 24 hours) associated with trauma-induced coagulopathy in blunt trauma without significant brain injury. METHODS: This study was a retrospective observational study using 516 blunt trauma patients without significant brain injury. The poor outcome group, including patients receiving massive transfusion and those who died within 24 hours, consisted of 33 patients (6.4%). The variables were compared between the poor outcome group and good outcome group, and logistic regression analysis was performed using statistically significant variables. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the poor outcome prediction ability of the initial d-dimer level. RESULTS: The poor outcome group showed more serious anatomical, physiological, and laboratory data than the good outcome group. In the ROC curve analysis for evaluation of the poor outcome prediction of the d-dimer level, the area under the curve value was 0.87 (95% confidence interval [CI], 0.84–0.90) while the cut-off value was 27.35 mg/L. In the logistic regression analysis, the high d-dimer level was shown to be an independent predictor of poor outcome (adjusted odds ratio, 14.87; 95% CI, 2.96–74.67). CONCLUSION: The high d-dimer level (>27.35 mg/L) can be used as a predictor for the poor outcome of patients with blunt trauma without significant brain injury.

Massage relieves inflammation and oxidative stress and promotes autophagy after contusion of skeletal muscles / 中华物理医学与康复杂志

Objective To observe the effects of massage on inflammation,oxidative stress and autophagy during the repair of acute contusion of skeletal muscles so as to explore its biological mechanisms.Methods Forty-two adult Sprague-Dawley rats were randomly divided into a control group (n =6),a model group (n =18),and a treatment group (n =18).Acute contusion of the gastrocnemius muscles of the rats in the model and treatment groups was inflicted using a home-made impactor.Beginning forty-eight hours later,15 minutes of massage was administered daily for two weeks.After one,7 and 14 days of the massage treatment,the injured gastrocnemius was resected from 6 rats of both the model and treatment groups.Morphological changes were observed using haematoxylin and eosin (HE) staining.The serum content of tumor necrosis factor alpha (TNF-α),interleukin1β (IL-1 β),C reactive protein (CRP) and prostaglandin E2 (PGE2) were detected using enzyme-linked immunosorbent assay (ELISA).The serum content of superoxide (SOD) and malondialdehyde (MDA) were detected using spectrophotometry.The expression of microtubule-associated protein 1 light chain 3 (LC3),Bcl-2 homeodomain protein Beclin1 and ubiquitin binding protein P62 were detected using Western blotting.Results The HE staining showed more significant collapse and swelling of cells in the model group than in the control group at each time point.New muscle cells were observed at days 7 and 14 in the model group.At each time point,significantly better recovery was observed in the treatment group compared to the model group,with more new muscle cells and better cell morphology.According to the ELISA results,a significant increase in serum pro-inflammatory factors occurred in the model group compared to the control group and compared to the treatment group after one day and 7 days of treatment.The average serum content of SOD and MDA in the model group was significantly higher than in the control group,while the average serum content of SOD in the treatment group was significantly higher than in the model group and that of MDA was significantly lower.Western blotting showed a significant decrease in LC3 (Ⅱ/Ⅰ) and Beclin1,as well as a significant increase in P62 in the model group at each time point compared with the treatment group and the controls.Conclusion Inflammation and oxidative stress increase significantly in a skeletal muscle after injury,but autophagy decreases significantly.Massage can effectively reduce the inflammatory response and oxidative stress and promote autophagy,which leads to quicker repair of skeletal muscles.

Review Of Ocular Injuries In Malaysia

Ocular injuries or trauma to the eye can be caused by variety of objects resulting in a spectrum of lesions in the eye. We did a Pubmed/Google/Science Direct search to review the spectrum of ocular injuries in Malaysia. In our review, we included 28 papers providing information on ocular injuries which were published from Malaysia during the period 1991-2016 in different medical journals. Prevalence was more among males with an average age of 35 years. Among adults they were more common in the workplace but in children it occurred at home. Few wore protective glasses at work. The mode of injury was due to sharp objects hitting the eye, motor vehicle and domestic accidents, firecrackers, chemicals and rarer causes like superglue and durian fruit. Prognostic factors for outcome were the initial visual acuity, length of the wound, associated factors like hyphaema, intraocular foreign body and vitreous prolapse. Missing the diagnosis of perforation of the eyeball is possible without eliciting a proper history. Protective devices must be worn to prevent injuries. Display of health education charts showing the effect of injuries in the eye and their preventive measures in health centres, private hospitals, schools, factories and sports centres will increase the awareness of public about the ocular injuries. It is important to diagnose the tissues involved in ocular trauma by the general practitioners and primary care physicians and refer the patients to the Ophthalmologist urgently for treatment to salvage vision. Compensation mechanisms should then be put forth in terms of rehabilitation and for monetary loss.

Intra-abdominal Organ Injuries in Blunt Injury Abdomen in SRM Medical College, Potheri: A Prospective Study.

Introduction: Blunt Abdominal trauma is the most common caused by road traffi c accidents (RTA). It also occurs as a result of fall from a height, assault with blunt objects, industrial mishaps, sports injuries, bomb blast. Investigative modality can only supplement the clinical evaluation and cannot replace it in the diagnosis of blunt abdominal trauma. In spite of the best techniques and advances in diagnostic and supportive care, the morbidity and mortality remain at large. Purpose: To estimate the frequency of various intra-abdominal organ involved, assess the various mode of blunt abdominal trauma and clinical presentation and various available investigation, treatment and complications. Methods: This a prospective study conducted in SRM Medical College among patients presenting to the casualty and general surgery outpatient department with a sample size of 72. Results: Males (91.6%) outnumbered females (8.33%). RTA forms the most common mode of injury. The most common age group affected is 21-30 years. Majority of the population presented with pain abdomen. Focused assessment with sonography for trauma has picked up solid organ injury in 46 cases. Computed tomography abdomen was performed in 100% of the population and forms the core investigation of choice and becomes more important in dealing operative versus conservative management. For splenic injury, the most common surgery performed was splenectomy (26 cases). Multiple intra-abdominal organs were involved accounting for 9.7%. Wound infection is the most common post-operative complication. The study showed a mortality of 19%. Conclusion: Blunt injury abdomen with solid organ injury forms a considerable load of patients in our society and is usually less obvious. Early diagnosis, repeated clinical examination and use of appropriate investigations form the key in the management.

The Use of Extracorporeal Membrane Oxygenation in the Surgical Repair of Bronchial Rupture / 대한구급학회지

Extracorporeal membrane oxygenation (ECMO) has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

Blunt Splenic Injury by Gunshot / 대한구급학회지

Trauma is frequently not purely penetrating or purely blunt. Such mixed trauma can result from the mechanism of injury. Recently, we encountered a patient who accidentally shot himself with a shotgun. He had a 15 x 8-cm-sized penetrating injury on left flank that did not penetrate into the peritoneal cavity and a blunt splenic injury with hemoperitoneum. Surgical and interventional treatments were performed for each injury. We present this case with a review of the related literature.

Asymptomatic Isolate Tricuspid Regurgitation with Chordae Tendineae Rupture Caused by Blunt Chest Injury / 영남의대학술지

The incidence and importance of tricuspid valve regurgitation after a blunt chest injury has risen with the increase in the number of automobile accidents and steering wheel traumas. This kind of injury has been reported more frequently in the last decade because of the better diagnostic procedures and understanding of the pathology. However, tricuspid valve regurgitation following a blunt chest injury can still be easily missed because most patients do not show symptoms at the time of the trauma. A 55-year-old male patient presented himself at our facility after suffering a chest injury from an automobile accident. His transthoracic echocardiography (TTE) revealed severe tricuspid valve regurgitation due to the prolapse of his anterior valve leaflet. We report a case of asymptomatic tricuspid regurgitation that developed after a blunt chest injury.
