Conservative management of traumatic chylothorax: a case report.

A case is presented of a right traumatic chylothorax, secondary to thoracic trauma with bilateral posterior eleventh rib fracture, treated by total parenteral nutrition and pleural drainage, with resolution within 2 weeks. On the basis of this clinical report and of a review of the literature, it is concluded that adequate conservative management should be initially the treatment of choice. Surgical treatment should be reserved to the cases in which clinical improvement does not occur within 2 weeks, and should consist of supradiaphragmatic thoracic duct ligation. Thoracoscopic fibrin glue injection has recently been described as a possible alternative treatment.

Chest injuries in children: an analysis of 100 cases of blunt chest trauma from motor vehicle accidents.

One hundred twenty-eight cases of chest injury were seen in a Paediatric Trauma Unit over a 5 1/2-year period. One hundred patients sustained motor vehicle accident (MVA)-related blunt chest injuries, 91 of them as pedestrians. Nine children had blunt chest injuries from falls, 10 had stab wounds (3 assault, 7 accidental), and 9 had gunshot injuries (6 from birdshot used by police during civil disturbance). MVA-related injuries were studied separately, as an etiologically homogeneous group. Sixty-five of these patients were under the age of 6. All but 3 also had serious extrathoracic injuries. The mean injury severity score (ISS) in MVA-related injuries was 25. Eight patients died, all with an ISS of 34 or more, 7 of whom had fatal head injuries. In MVA-related injuries, pulmonary contusion (n = 73) was the most frequent lesion seen, followed by rib fracture (n = 62), posttraumatic effusion (n = 58), pneumothorax (n = 38), and pneumatocele (n = 5). In MVA-related injuries, 18 children required ventilation. Thirty-nine (69%) of 56 children with radiologically evident posttraumatic pleural effusion had intercostal chest drainage. Analysis suggests that lung injury is a central event in MVA-related blunt chest trauma. Primary lung injury, radiologically visible as contusion, is complicated by hematoma, posttraumatic effusion, and pneumothorax.

Thoracic trauma.

The physiologic equilibrium of chest injury patients is frequently precarious, and mild stress during examination and treatment may precipitate acute decompensation and death. This is particularly true with the respiratory system, where the normally large respiratory reserve capacity may be rapidly lost. Accurate assessment of the nature of the thoracic injury and the severity of that injury must be determined in order to formulate a therapeutic plan. Many thoracic injuries, such as pneumothorax, pulmonary contusions, or rib fractures, will be self-limiting. Other conditions must be recognized for their potentially lethal nature and dealt with aggressively, and these include cardiac tamponade, tension pneumothorax, and esophageal perforation. By performing a systematic evaluation of the patient and confirming or denying the presence of all possible types of thoracic injury, the veterinarian may avoid overtreatment of self-limiting lesions and recognize and aggressively treat those with potentially fatal outcomes.

Case report: catheter-related epidural abscess.

INTRODUCTION: Catheter-related spinal epidural abscesses are rare but increasing in incidence. CLINICAL PICTURE: An elderly gentleman received 4 days of continuous epidural analgesia following multiple traumatic rib fractures. Five days subsequently, he developed an extensive epidural abscess accompanied by backache, lower limb weakness, fever, leukocytosis and Staphylococcal bacteraemia. TREATMENT: He received appropriate intravenous antibiotics and underwent an emergent decompressive laminectomy. OUTCOME: A good outcome was achieved because of prompt diagnosis, appropriate intravenous antibiotics and timely surgical intervention. CONCLUSIONS: It is important to be vigilant and continue to maintain good clinical practice and a high index of suspicion for this procedural-related complication.

Thoracic injuries. A review of 93 cases.

A report is presented of 93 patients referred for specialist management of thoracic injuries in the 5-year period 1973-1978. Penetrating trauma to the thorax had been sustained by 18 patients and blunt trauma by 75. Falls and traffic accidents were the most common causes (32 and 35 cases). Rib fractures were the most frequent lesions, and 10 of these 67 patients had flail chest. Hemothorax and/or pneumothorax were found in four-fifths of the patients. The diaphragm was torn in five cases. Three had lesions of the heart and/or pericardium and one patient had a tracheal lesion. Closed pleural drainage was the most commonly used treatment. Thoracotomy was performed in 10 of the 93 patients. The mortality rate in the series (10%) agreed with findings from other, similar studies.

[Traumatic aortic regurgitation complicating chronic bronchitis; report of a case].

A 61-year-old man with diabetes mellitus and chronic bronchitis was brought to the hospital after falling from a roof accidentally. He received blunt trauma to the left chest wall including left rib fractures, pneumothorax, hemothorax and a fracture of left scapula. After endotracheal intubation and chest drainage, he was transferred to the intensive care unit. Sixteen days later, congestive heart failure appeared. Echocardiography showed a severe aortic valve regurgitation with a prolapse of non-coronary cusp. Eight months after the injury, his heart failure deteriorated. He underwent aortic valve replacement with a mechanical prosthesis. Upon examining the aortic valve, we noted 2 perforations in the non-coronary cusp of the aortic valve. Postoperative course was uneventful.

Unrecognized pneumothorax as a cause of intraspinal air.

STUDY DESIGN: This is a case report. OBJECTIVE: A case of intraspinal air in a polytraumatized patient with unrecognized pneumothorax after blunt chest trauma is reported. SUMMARY OF BACKGROUND DATA: In most cases, intraspinal air is associated with degenerative disc disease, epidural abscess, or synovial cyst, or it follows iatrogenic manipulation. Scialdone and Wagle first reported a case of intraspinal air due to a laceration of the right main bronchus. No previous case of intraspinal air after a simple unsuspected pneumothorax following blunt chest trauma has been reported. METHODS: During routine x-ray and computed tomography examination of a polytraumatized patient, an unsuspected pneumothorax due to a rib fracture was detected in a thorax computed tomography scan. Computed tomography scans of the cervical spine showed a collection of intraspinal air. RESULTS: The computed tomography examination of a polytraumatized patient with an unsuspected pneumothorax after blunt chest trauma showed the embolization of air in the paravertebral vein plexus and in the intraspinal canal. CONCLUSION: These observations suggest a wider indication for computed tomography scans of the thorax in blunt chest trauma. Also, whenever intraspinal air is found in the diagnostic course of a traumatized patient, a hidden pneumothorax should be suspected and ruled out.

Diaphragmatic rupture and the association with occupant position in right-hand drive vehicles.

Ruptured diaphragm following blunt trauma occurs with an incidence of 3 to 8% with right-sided rupture recognised with increasing frequency. This study aimed to investigate the influence of occupant position in right-hand drive (RHD) vehicles on the side of diaphragmatic injury. A retrospective analysis of the Scottish Trauma Audit Group database was performed to gather data on blunt diaphragmatic lacerations. Police records were also searched to ascertain the point of impact in the accidents studied. In total, 35 patients were studied, 25 drivers and 10 front-seat passengers. The incidence of right-sided rupture was 40% in drivers and 20% in FSPs. The incidence of associated pulmonary contusion, rib fracture and liver injury was also higher in drivers. Given the small sample size, these differences were not statistically significant, but they show an interesting trend. The right side of a driver's body is more exposed to injury in RHD vehicles, a fact that explains the significant association between driver's side impact and right-sided rupture. As right-sided injury is more difficult to detect, it is important that a high index of suspicion is maintained, especially when managing drivers from RHD vehicles.

Mitral valve plasty for mitral regurgitation after blunt chest trauma.

A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

Laceration of the liver with delayed massive intra-abdominal hemorrhage: a case report of child abuse.

A 3-year-old girl was found unresponsive in the bedroom and expired at a hospital. Autopsy revealed massive intra-abdominal bleeding due to laceration of the liver and mesenterium with multiple rib fractures and multiple fresh and old bruises. The time of the assault causing the liver trauma was questioned because the perpetrator, her mother's boyfriend, denied any outrages on that particular day although he confessed that he had physically abused her for several months. Microscopically, numerous polymorph leucocytes infiltrated exclusively surrounding the lacerated area of the liver. Many hepatocytes were necrotic and cord arrangement of the parenchymal cells was destroyed. There should be a certain time lag between the major assault and massive intra-abdominal hemorrhage, which was not inconsistent with the statement of the perpetrator.

[Emergency surgery for chest injuries in the multiply injured: a systematic review].

OBJECTIVE: Severe chest injuries are still associated with significant morbidity and mortality. This systematic review assesses the early operative management of severe chest trauma in multi injured patients with special regard to the priority of the operative therapy. METHODS: Clinical trials were systematically sought and collected (MEDLINE, Cochrane and hand searches). Of 618 abstracts, 46 articles were selected for detailed appraisal and were classified into evidence levels (1 to 5 according to the Oxford system). RESULTS: Penetrating chest injuries in haemodynamically instable patients require emergency operative therapy. A thoracotomy is also indicated in excessive chest tube output (>1500 ml). An aortic rupture can be treated either by open suture or-in borderline patients-by endovascular stenting. In selected haemodynamically stable patients delayed treatment is also possible. Lesions of the tracheobronchial system should be treated urgently with primary surgical repair. Diaphragmatic ruptures should be closed urgently. Surgical stabilisation of rib fractures with an associated flail chest reduces the ventilator days and the length of intensive care unit stay. CONCLUSION: A large part of early surgery for chest injuries is justified because it averts immediate threats to life (level 1c evidence). No randomised and only a few controlled trials have examined the relative value of the different surgical options so far. Long-term data are lacking especially on the safety of endovascular stenting.

Thoraxsonography--Part I: Chest wall and pleura.

The fact that ultrasound (US) waves are reflected completely by the bony thorax and are erased from the aerated lung to a large extent led to the mistaken notion that sonography is not a very useful diagnostic tool for use in this region. On the other hand, since the beginning of US imaging, reports have been published regularly on pleuropulmonary sonographic diagnostic and therapeutic procedures. Rib fractures could be detected about twice as often by US than x-ray. With regard to determining the nodal status in neoplastic disease of the axilla and supraclavicular fossa, US is superior to palpation. In imaging pleural effusions, US is more accurate than chest film and is useful in determining the nature of the pleural effusion. Sonographic evidence of pleural nodules is a specific finding in patients with a malignant effusion. Chest sonography is a useful diagnostic tool for critically ill patients with chest diseases. Performed at the bedside, this technique can be particularly helpful when computed tomography is not available or when critically ill patients cannot be moved.

[Thoracic trauma in childhood. Radiologic findings].

In childhood blunt trauma to the chest wall is more frequent than penetrating injuries. Most of these are the result of traffic accidents. Solitary or serial rib fractures are seen more often than fractures of the sternum. Complications of thoracic injuries are pulmonary contusion, hemothorax and, less frequently, pneumothorax. Pulmonary contusion can result in post-traumatic pneumatocele or chronic pulmonary hematoma. Injuries of the heart, the great vessels and bronchotracheal rupture, presenting initially with pneumothorax, followed by atelectasis, rarely occur. Blunt thoracic trauma is frequently associated with further injuries (head and/or blunt abdominal trauma). The prognosis also depends on the concurrent injuries. The initial evaluation of an injured child is based on the chest X-ray and abdominal ultrasound examination. Additional information can be obtained by a CT scan in mediastinal injuries.

Massive injury to the heart after attempted active compression-decompression cardiopulmonary resuscitation.

An 84-year-old woman was unsuccessfully resuscitated for 3 min using standard cardiopulmonary resuscitation (CPR), followed by 15 min of active compression-decompression (ACD). The autopsy revealed that death was due to myocardial infarction complicated by rupture of the infarcted area and pericardial tamponade was diagnosed. Furthermore, a series of rib fractures, a transverse fracture of the sternum, rupture of the pericardial sac, the right ventricle, both atria and lacerations of the ascending aorta, were found with no signs of a vital reaction. To our knowledge, such extensive cardiac injury after CPR has not been previously reported. It is suggested that the pre-existing pericardial tamponade, the age of the patient and the application of the ACD-device to incorrect areas of the chest contributed to the extent of the cardiac injury. This case further adds to the suspicion of an increased risk of cardiac injuries when using an ACD device for cardiac massage.

Abnormalities of the thoracic bellows: stress fractures of the ribs and hiatal hernia.

The thoracic bellows mechanism consists of the rib cage and the diaphragm. The purpose of this study was to determine if nontraumatically acquired lesions of the bellows were secondary to underlying disease. Abnormalities of the bellows, specifically stress fractures of the ribs and hiatal hernia, were found in 21 dogs and cats with underlying cardiopulmonary disease, neuromuscular disease, or metabolic disease. A case-control study of Bulldogs demonstrated that hiatal hernia was associated with the more severe manifestations of brachycephalic syndrome. Stress fractures occurred mostly in females and in cats, and involved multiple ribs. Fractures were usually related to severe respiratory effort, but also occurred in association with metabolic disease. Hiatal hernia was also associated with severe respiratory effort, but may be exacerbated if a neuromuscular disorder affecting the diaphragm is present. Abnormalities of the thoracic bellows, such as rib stress fractures and hiatal hernia, may be signs of underlying disease, rather than being primary causes of disease.

Pediatric thoracic trauma.

Although thoracic injuries occur less frequently in children than adults, they remain a source of substantial morbidity and mortality. Disparate problems such as rib fractures, lung injury, hemothorax, pneumothorax, mediastinal injuries, and others may present in isolation or in combination with one another. Knowledge of the manner in which pediatric anatomy, physiology, and injury patterns change with age may expedite the evaluation of the pediatric chest after trauma. Differences in pulmonary functional residual capacity, blood volume, chest wall and spinal soft-tissue mobility, and cardiac function may translate into problems or benefits of important consequence. For example, although more predisposed to hypoxemia, young children may remain well compensated hemodynamically, despite significant blood loss. Rare injuries in children, such as cardiac and great vessel trauma, may remain undiagnosed precisely because of their scarcity and protean symptoms.

[Rupture of the diaphragm--a frequently undetected injury].

Traumatic ruptures of the diaphragm are acquired separations of the diaphragm which are aetiologically divided into indirect and rare direct ruptures. The force required to produce indirect ruptures will usually lead to additional intraabdominal lesions of liver and spleen as well as to rib fractures and fractures at the lower extremity. Hence the sequels of these accompanying lesions are often prominent in the clinical pattern to such an extent that 50 to 70% of the diaphragmatic ruptures remain primarily unrecognised. Abdominal and/or cardiorespiratory signs and symptoms become manifest only if there is an evisceration. Hence surgical strategy in preoperatively identified diaphragmatic ruptures depends on the localisation of the rupture, on the severity of the accompanying lesions, and the time until surgical treatment can be effected. Depending on the type and severity of the accompanying lesions an average lethality of 33% must be taken into account in fresh diaphragmatic ruptures. In chronic uncomplicated eviscerations the operations lethality is about one per cent.
