[Thoracic drainage. What is evidence based?].

Pleural drainage becomes a vital measure to restore physiological conditions in cases of loss of pleural negative pressure, regardless its etiology. Therefore, it is not surprising that hardly any evidence based publications on this topic are available. For the treatment of pleural empyema,the history of pleural drainage goes back to antiquity.Nowadays, quite a number of synonymously used terms are wrongly employed instead of the correct terms of thoracic or pleural drainage. Indications for placing a pleural drainage are: pneumothorax, pleural effusion, pleural empyema,hemothorax and chylothorax. As a standard method, it is recommended that the pleural drainage be placed in the fifth or sixth intercostal space in the anterior axillary line. It is not advisable to use a closed insertion with the help of a trocar due to the significantly increased risk of injury. The insertion of a pleural drainage when correctly placed is a safe procedure; rare typical complications involve the wrong placement of the drainage, hemorrhage or infection like pleural empyema. The complication rate, however, does not exceed 3%.

[The value of thoracoscopy in thorax trauma].

A hemodynamically stable patient presenting with persistent bleeding through his chest tube (ICD) is a classic indication for early thoracoscopic intervention in trauma. The source of bleeding and air leaks can be identified and often treated: bleeding and perforated pulmonary segments can be resected, and chest wall bleeding may be coagulated or sutured. Injuries to the diaphragm are difficult to diagnose, as they might not be seen in conventional trauma imaging without gross herniation of intra-abdominal contents into the thoracic cavity. Identifying the site of diaphragm perforation can give useful hints in thoracoabdominal trauma, identifying injured cavities and localizing the bullet or stab tract. Most often, diaphragmatic defects may be closed during diagnostic thoracoscopy as well. Non- or partially drainable hemothorax is another indication for thoracoscopy. Coagulated blood can be mechanically mobilised, and aspirated or primary bleeding may be stopped. Effective lavage and a high-performance suction device are required. Correct placement of the drainage is part of optimized therapy, along with inspection of all intrathoracic organs and surfaces. Furthermore, surgical and anaesthesiological teamwork and experience are prerequisites for the fast, professional application of a minimally invasive thoracoscopic approach in chest trauma patients. Diagnostically and theurapeutically, thoracoscopy plays an important role in the trauma setting--in the case of hemodynamically stable patients.

[Rupture of the azygos vein by blunt thoracic trauma. A case report and literature review].

Blunt chest trauma is a common injury in traffic accidents. Thoracic vessel trauma frequently affects intercostal arteries, the aorta and less often the subclavian artery. Azygos vein injury is uncommon and has previously been described in only 19 cases. The 20th case of blunt azygos vein injury due to high energy trauma as a consequence of a traffic accident is reported with a review of the literature. Preoperative diagnosis was performed by computed tomography. Azygos vein injury is rare but potentially lethal (8/20, 40.0%). Chest radiograph with right hemothorax is reported consistently except for two cases. Fractures of ribs and/or thoracic spine (T3-5) were found in nine patients, while neither were found in 11/20 cases. Pathognomonic signs have not been described in the literature. Early resuscitation and immediate thoracotomy with recognition and treatment of azygos vein rupture is necessary to avoid a fatal outcome.

[Chest injury. Part I: Significance--symptoms--diagnostic procedures].

Chest injuries can be sustained in isolation or in association with multiple injuries. Life-threatening complications may ensue because organs that are vital to survival of the organism are situated within the thoracic cavity. These complications include airway obstruction, tension pneumothorax, wide open pneumothorax, flail chest, cardiac tamponade and massive hemothorax. The mortality of patients hospitalized with chest injury can be as high as 10%. Clinical examination and awareness of the possibility of other injuries (high level of suspicion) are essential, and standard chest X-ray, ultrasound and thoracic computed tomography may also be needed for the diagnosis. The first part of this serial paper on the management of chest injuries focuses on anatomical aspects, pathophysiology and symptoms, but mainly on the indications for the standard diagnostic procedures and further high-tech examinations.

Pulmonary arteriovenous fistula: presentation, diagnosis, and treatment.

Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations of the lung. There is a strong association with Rendu-Osler-Weber disease. Although most patients are asymptomatic, PAVFs can cause dyspnea from a right-to-left shunt. They can also bleed and result in hemoptysis and hemothorax. Because of paradoxical emboli, various central nervous system complications have been described including stroke, and brain abscess. Currently, spiral computed tomography offers the most practical method for establishing the presence of PAVFs. Most patients should be treated. Therapeutic options include angiographic embolization with metal coils or balloon occlusion and surgical excision. Angiographic treatment has become the mainstay of therapy for most patients during the last decade. It is less invasive and can be repeated easily. Surgery, which usually consists of a conservative lung resection, is associated with low morbidity and a low recurrence rate. Both therapeutic approaches are discussed. The Mayo Clinic surgical experience of the last 20 years for PAVFs is presented.

Mesothelial lamellar bodies in norm and experimental conditions. Transmission and scanning electron microscopic observations on the peritoneum, pleura and pericardium.

The ultrastructural characteristics of the mesothelial intracellular and extracellular lamellar bodies (LB) in norm, and especially in pathological conditions are still unknown. After routine fixation procedure, material from organs in the three serous cavities of Wistar rats, as control group were compared with animals following experimental hemothorax (EH) and experimental peritonitis (EP), using transmission and scanning electron microscopy (TEM, SEM). Different membrane-bound profiles, short strip-like structures and single LB characterize the control group. Five days after EH small groups of LB were observed. Single balloon-like profiles, numerous particles and larger groups of LB with wide varieties in size, form and membrane structure characterize the 8th day after EH. Thin and concentric membranes build single LB the 5th day of EP. Eight days after the same treatment, groups of LB, complex structures with several multilamellar centers, strip-like structures with rough granulo-filamentous material and uninterrupted covering over wide areas were observed. We conclude that constant components in the untreated rats are different membrane profiles, as initial lamellar formations and single typical LB with predominant intracellular position. The preferable sites for exocytosis of LB are the intercellular spaces. The present data demonstrate simultaneous findings of the two main groups of formations by using routine fixation in the control group and in the treated animals. The first represent LB as well as other round profiles, observed by TEM and particles, observed by SEM, which are widespread and probably have a basic role. The second ones are strip-like structures and its SEM-equivalents, i.e. uninterrupted covering. TEM-profiles and their SEM-images show significant organ differences and in some cases lack of correspondence between both electron microscopic techniques in the same treatment. Significant enlargement of the number of LB and the length of the strip-like structures characterize the mesothelium after pathologic conditions. LB with considerable differences in the structure and larger particles over the microvillous border predominate after EH. Strip-like profiles, continuous covering and smaller groups of LB with similar morphology and preferable submesothelial position characterize the mesothelium after EP.

Bilateral internal thoracic artery injury induced by blunt trauma.

A case is reported of a 52-year-old man with bilateral internal thoracic artery (ITA) injury induced by blunt trauma. He was a laborer at a construction site who was hit on the anterior chest by a ceiling block. On arrival at the hospital at one hour after the accident, his general condition was good, and the chest computed tomography (CT) showed a slight hematoma at the mediastinum. However, at 4 hours after the trauma, the blood pressure fell, and the CT showed a large anterior mediastinal hematoma with bilateral hemothorax. A median sternotomy revealed bilateral ITA injury at the level of the 3rd intercostal space and incomplete fractures in the sternum and bilateral rib cartilages. Although hemostasis was achieved by ligation of the injured ITA, bleeding re-occurred from the ITA at the level of the 2nd intercostal space, and this was stopped by a second operation. The patient recovered without any further significant complication. The rarity of blunt trauma-induced ITA injury is discussed, including the mechanism, diagnosis, and treatment.

Major surgical intervention during extracorporeal membrane oxygenation.

Of 135 patients treated with extracorporeal membrane oxygenation (ECMO) between January 1987 and December 1989, 19 (14.0%) patients underwent surgical procedures while on ECMO. Thirteen (68%) patients had operations related to hemorrhage, including cannula site (6), mediastinal (1), hemoperitoneum (3), and hemothorax (3). Six of 13 patients required repetitive operations for bleeding; 4 of 6 died. Six (35%) patients had operations for congenital pathology including patent ductus (PDA) ligation (2), repair of transposition of the great vessels (2), repair of coarctation (1), and repair of congenital diaphragmatic hernia (3). One patient had multiple simultaneous procedures performed. Of these 6 patients, 4 were decannulated immediately and 2 were decannulated within 28 hours following surgery without any bleeding complications. Fifteen of 19 patients were operated on in the neonatal intensive care unit. The 4 remaining patients required transport on ECMO to the surgical suite. Thirteen of the 19 patients requiring surgical intervention on ECMO survived. In the 13 survivors, the mean time to decannulation postoperative was 45 hours, and in those that died it was 90 hours. Our experience suggests that surgical intervention while on ECMO is technically feasible with the best results achieved when rapid discontinuation of ECMO can be accomplished postoperatively. Due to this fact major surgical intervention should be postponed if possible until near the conclusion of the ECMO therapy.

Massive osteolysis of the chest in children: an unusual cause of respiratory distress.

Massive osteolysis, also called Gorham's disease, is an uncommon disease in which bone virtually disintegrates and is replaced by vascular fibrous connective tissue. The authors treated two children with massive osteolysis of the chest. Both conditions responded well to radiation therapy; one even showed evidence of reossification. Massive osteolysis should be considered in children who have spontaneous hemothorax. The bony structures should be examined for evidence of lytic lesions.

A randomized clinical trial of rib belts for simple fractures.

The authors present a pilot study in which 20 patients with simple rib fractures were randomized prospectively into two treatment groups. One group received ibuprofen and the other group ibuprofen plus a rib belt for analgesia. There were no statistically significant differences observed in pulmonary function testing between the groups at initial visit, 48 hours, or 5 days. Atelectasis developed in four patients, two in each treatment group; there were no cases of pneumonitis. Patients with displaced rib fractures experienced a higher rate of hemo- or pneumothorax than did those with nondisplaced fractures (5/10 v 1/10). Patients with displaced fractures who used rib belts experienced a higher rate of hemothorax than those using oral analgesia alone (4/6 v 1/4). Patients using rib belts uniformly reported a significant amount of additional pain relief. The clinician can use a rib belt to provide additional comfort to the patient with fractured ribs without apparent additional compromise to respiratory parameters. A further study stratifying displaced and nondisplaced fractures has been initiated to clarify the possible contributing roles of displaced rib fractures and the rib belt in patients with displaced fractures.

Association between major injuries and seat locations in a motorcoach rollover accident.

Motorcoaches and buses have the highest accident rate among different kinds of vehicles in Taiwan. It is, therefore, important to modify motorcoach designs so that they increase passenger safety. We collected patient data from a motorcoach rollover accident to assess the major injuries of the passengers and the associated risk factors for each type of injury. The accident occurred on a summer day in 2003 in central eastern Taiwan. A double-decker motorcoach carrying 46 passengers and a driver rolled over onto its left side on a downhill path because the coach's brakes failed. On the upper deck, the coach had four columns of seats, two on either side of a center aisle: 12 pairs on the left side, and 10 pairs on the right. Of the 41 seated people on the upper deck, the passengers in the down side (left seats) of each pair of seats had higher Injury Severity Scores than those in the up side (right seats), and passengers >or=65 years old had relatively higher rates of hemothorax and head injuries with subarachnoid hemorrhage or intracranial hemorrhage than those <65. Multivariate analysis showed that age >or=65 years and sitting on the down side at the time of rollover were independent risk factors for major injuries. Our analysis of the data from this motorcoach rollover accident showed that most major injuries occurred as passengers in the up side seats were thrown from their seats and compressed the neighboring passengers in the down side. We hypothesize that occupant restraint devices, such as seat belts, might prevent or reduce some injuries in motorcoach rollover accidents.

[Intraspinal air, a rare complication of blunt chest trauma].

Pneumorachis, defined as the presence of air within the spinal canal, has rarely been described, and is exceptionally due to thoracic trauma. We report the case of a 37-year-old patient who sustained a motor vehicle accident. The chest CT-scan showed a bilateral-hemothorax, a small right pneumothorax, rib fractures, and a fracture of the fourth thoracic vertebra associated with air in the spinal canal extending from T6 to L2. The fracture of T4 associated with the pleural lesion is probably responsible for the pneumorachis. Possible pathogenic mechanisms of this rare blunt chest complication are discussed.

Video-assisted thoracic surgery utilizing local anesthesia and sedation.

OBJECTIVE: Video-assisted thoracic surgery (VATS) is usually performed with general anesthesia and double-lumen endotracheal intubation, but minor procedures have been carried out with patients spontaneously breathing and with epidural or regional analgesia. We have broadened our indications for VATS utilizing purely local anesthesia and sedation. METHODS: The medical records of all patients undergoing VATS under local anesthesia and sedation at Geisinger Wyoming Valley Medical Center between 7/1/02 and 6/1/06 were reviewed. All procedures were performed in the operating room with patients in full lateral position; no patient had endotracheal intubation or epidural or nerve block analgesia. RESULTS: One hundred and fifteen patients, ranging in age from 21 to 88 years and in size from 40 to 172 kg, underwent 126 video-assisted thoracic operations: pleural biopsy/effusion drainage with or without talc 81, drainage of empyema 21, lung biopsy 18, evacuate hemothorax 3, pericardial window 2, biopsy chest wall mass 1. No patient required intubation or conversion to thoracotomy. Three patients who underwent lung biopsy died of their underlying disease (cytomegalovirus and pneumocystis, primary amyloidosis, metastatic cancer to contra-lateral lung) on postoperative days 18, 14, and 4, respectively. One patient developed transient renal insufficiency attributed to ketorolac. CONCLUSION: VATS utilizing local anesthesia and sedation is well tolerated, safe, and valuable for an increasing number of indications.

Diaphragmatic injuries in children after blunt abdominal trauma.

BACKGROUND: Traumatic rupture of the diaphragm resulting from blunt abdominal trauma remains a challenging clinical entity. Description of such type of injuries in children is scarce in the literature. PURPOSE: The aim of this study was to present this special form of injury in the pediatric age group and compare the different aspects of diaphragmatic injury with that occurring in adults. PATIENTS AND METHODS: Ten cases of diaphragmatic rupture after blunt trauma in children were reported. The presentations, findings, and management were described. RESULTS: This study included 7 boys and 3 girls aged 3 to 16 years. Trauma in 8 cases resulted from motor vehicle or auto-pedestrian accidents and 2 from falling from a height. Chest radiograph shows suggestive signs of diaphragmatic injuries in 7 occasions including intrathoracic visceral herniation in 4 cases and hemothorax in 3 cases. Associated injuries were found in 5 cases in the form of rib fractures in 3 cases and lung contusion in 2 cases. Lung tear, gut perforation, and liver tear were each reported once. Isolated diaphragmatic injury is reported in 5 cases. Three cases were repaired via thoracotomy or laparo-thoracotomy and 7 cases via midline laparotomy. On exploration, we found diaphragmatic avulsion of the costal origin in 5 cases, 3 left and 2 right contrary to tears, of which 4 were left sided and 1 right sided. Primary repair was conducted in 7 cases and an intercostal muscle flap was used in 3 cases. No mortalities were reported. CONCLUSIONS: This series of diaphragmatic rupture in children reveals the following: (1) Avulsion of the costal origin of the diaphragm is a peculiar type of injury described in children (5 of 10). (2) The intercostal muscle flap is a useful tool to bridge diaphragmatic defects. (3) Isolated diaphragmatic injuries do occur in children more frequently than in adults. (4) As in adults, diaphragmatic rupture prevails in the left side, and purposeful surgical diagnosis and early management determine the effectiveness of treatment.

Transthoracic cuffed hemodialysis catheters: a method for difficult hemodialysis access.

BACKGROUND: Recurrent vascular access failure is a major cause of morbidity in patients receiving long-term hemodialysis. Central venous catheters are often necessary for dialysis, and easily accessed vessels (ie, the internal jugular vein and subclavian vein) frequently occlude because of repeated cannulation. When standard access sites occlude, unconventional access methods become necessary. We report a technique of placing hemodialysis catheters directly into the superior vena cava (SVC). METHODS: Between January 2002 and December 2004, 22 patients with documented bilateral jugular and subclavian vein occlusion underwent transthoracic SVC permanent catheter placement. Femoral vein access was obtained, and a sheath was placed. Under fluoroscopic guidance, a diagnostic catheter was then inserted into the SVC, and a venogram was obtained. By using the fluoroscopic image as a reference guide, supraclavicular access directly into the SVC was performed with lateral and anteroposterior views to better localize the SVC. Once venous blood was obtained, a hydrophilic wire was passed into the inferior vena cava. A 5F sheath was then placed, and, with the use of an exchange catheter, the wire was switched for a stiffer wire. The hemodialysis catheter was then placed in the standard fashion over this wire. RESULTS: In a 24-month period, 22 patients underwent transthoracic permanent catheter placement. All patients had the permanent catheters successfully inserted. Two major complications occurred. One patient experienced a pneumothorax, and another patient experienced a hemothorax. Both patients were successfully treated with chest tube decompression. All permanent catheters functioned immediately with a range of 1 to 7 months. CONCLUSIONS: Transthoracic permanent catheter placement is an appropriate alternative for patients in whom traditional venous access sites are no longer available.

Computed tomography in the diagnosis of blunt thoracic injury.

BACKGROUND: Computed tomography (CT) is an important diagnostic modality in the evaluation of blunt head and abdominal injuries, but it has not been routinely used to evaluate blunt chest trauma. METHODS: One hundred seventy stable patients with blunt thoracic trauma were evaluated with chest x-ray (CXR), and subsequently by CT. RESULTS: Of a total of 131 fractures, 53% were identified on initial CXR, 39% on CT, and 26% were not seen on either study. Twenty-one pneumothoraces were seen on CT but not on CXR. Chest tubes were placed in 8 patients and 12 patients were observed without incident. One hemothorax identified by CT scan alone required treatment. Four of 6 diaphragmatic injuries were seen on CT and 2 on CXR. Parenchymal abnormalities were apparent in 189 lung fields on CT and in 66 lung fields on CXR. Most represented atelectasis and did not require treatment. Altogether, CT scanning resulted in changes in management for 11 patients (6%). CONCLUSIONS: Although CXR is less sensitive in detecting parenchymal and pleural injuries than CT, the majority of the injuries identified by CT alone are minor and require no treatment. CXR remains the primary modality for diagnostic evaluation of blunt thoracic trauma.

Ruptured thymoma causing mediastinal hemorrhage resected via partial sternotomy.

A case of a ruptured thymoma causing mediastinal hemorrhage and hemothorax that was electively resected by a partial sternotomy approach is presented. This case and others previously reported illustrate that a sudden onset of dyspnea and chest pain accompanied by acute mediastinal widening on chest roentgenogram in a previously healthy patient should suggest the diagnosis of a ruptured thymoma. An upper part sternotomy approach may be as safe and effective as a less invasive surgical procedure in resection of noninvasive thymomas, even if dense tumor adhesion exists.
