Endovascular repair of aortic lesions associated to video-assisted thoracoscopy surgery after chest trauma

AIM: Trauma of the thoracic aorta for blunt trauma shows a very high incidence of mortality. Hospital mortality rate after aortic open surgery is between 15% and 30%. Endovascular management represents an alternative treatment Associated lesions are usually seen in those critical patients. Hemothorax may be present. The authors propose a combined treatment of endovascular repair for the aortic lesion and video-assisted thoracoscopy surgery (VATS) for the treatment of chest bleeding complications. METHODS: The authors report a series of three patients with post-traumatic aortic lesion and hemothorax. In two patients endovascular procedure was first performed, followed by VATS, few days later, for retained hemothorax. In the third patient the two procedures were performed at the same time because of the patient's critical conditions. RESULTS: There was technical success of stent-graft placement in all the treated cases. No postoperative mortality. No postoperative paraplegia. No VATS converted to thoracotomy. The postoperative follow-up time range between 10 and 19 months. CONCLUSION: Considering the relatively short procedural time and minimally invasive approach of both techniques, the concomitant use of them may represent an alternative to standard open surgery in cases of thoracic aorta lesions associated with hemothorax. Those procedures may be performed sequentially or together in emergency cases with intra-thoracic more active bleeding to exclude or to treat intra thoracic bleeding.     

Video-assisted thoracoscopy as an important tool for trauma surgeons: a systematic review

Purpose

Trauma patients frequently have serious chest injuries. Retained hemothoraces and persistent pneumothoraces are among the most frequent complications of chest injuries which may lead to major, long-term morbidity and mortality if these complications are not recognized and treated appropriately. Video-assisted thoracoscopy (VATS) is a well-established technique in surgical practice. The usefulness of VATS for treatment of complications after chest trauma has been demonstrated by several authors. However, there is an ongoing debate about the optimal timing of VATS.

Methods

A computerized search was conducted which yielded 450 studies reporting on the use of VATS for thoracic trauma. Eighteen of these studies were deemed relevant for this review. The quality of these studies was assessed using a check-list and the PRISMA guidelines. Outcome parameters were successful evacuation of the retained hemothorax or treatment of other complications as well as reduction of empyema rate, length of hospital stay, and hospital costs.

Results

There was only one randomized trial and two prospective studies. Most studies report case series of institutional experiences. VATS was found to be very successful in evacuation of retained hemothoraces and seems to reduce the empyema rate subsequently. Furthermore, the length of hospital stay and costs can be drastically reduced with the early use of VATS.

Conclusion

Early VATS is an effective treatment for retained hemothoraces or other complications of chest trauma. We propose a clinical pathway, in which VATS is used as an early intervention in order to prevent serious complications such as empyemas or trapped lung.

Management of simple and retained hemothorax: A practice management guideline from the Eastern Association for the Surgery of Trauma

BackgroundTraumatic hemothorax poses diagnostic and therapeutic challenges both acutely and chronically. A working group of the Eastern Association for the Surgery of Trauma convened to formulate a practice management guideline for traumatic hemothorax.MethodsWe formulated four questions: whether tube thoracostomy vs observation be performed, should pigtail catheter versus thoracostomy tube be placed to drain hemothorax, should thrombolytic therapy be attempted versus immediate thoracoscopic assisted drainage (VATS) in retained hemothorax (rHTX), and should early VATS (≤4 days) versus late VATS (>4 days) be performed?A systematic review was undertaken from articles identified in multiple databases.ResultsA total of 6391 articles were identified, 14 were selected for guideline construction. Most articles were retrospective with very low-quality evidence. We performed meta-analysis for some of the outcomes for three of the questions.ConclusionsFor traumatic hemothorax we conditionally recommend pigtail catheters, in hemodynamically stable patients. In patients with rHTX, we conditionally recommend VATS rather than attempting thrombolytic therapy and recommend that it should be performed early (≤4 days).     

Evaluation of chest tube administration of tissue plasminogen activator to treat retained hemothorax

Background

When retained hemothorax occurs, video-assisted thoracoscopy or thoracotomy is performed, but recently, tissue plasminogen activator (tPA) has been used. This study evaluated intrapleural tPA use for retained traumatic hemothoraces.

Methods

A retrospective review was conducted of trauma patients treated with intrapleural tPA for retained hemothorax. Data included demographics, past medical and surgical histories, injury details, treatment details, and outcomes.

Results

Seven patients (median age = 47 years, male = 6, blunt trauma = 6) met study criteria. All patients received a chest tube. Six patients later received computed tomography-guided drains for tPA infusion. Number of tPA treatments per patient varied from 1 to 5. Median total tPA dosage was 24 mg. Median time from injury to chest tube placement was 11 days and from chest tube placement to first tPA treatment was 4 days. No patients required a video-assisted thoracoscopy; however, 1 patient required thoracotomy. There were no deaths or bleeding complications attributed to intrapleural tPA.

Conclusion

Although future studies are needed to identify optimum treatment guidelines, intrapleural tPA appears to be a safe and efficacious treatment option.     

Comparative analysis of chest tube thoracostomy and video-assisted thoracoscopic surgery in empyema and parapneumonic effusion associated with pneumonia in children

BACKGROUND: Controversy exists regarding the optimal management strategy for children having empyema or parapneumonic effusion as a complication of pneumonia. We hypothesized that video-assisted thoracoscopic surgery (VATS)-assisted drainage of pleural fluid and debridement of the pleural space is superior to a chest tube alone in the management of these patients. We further identified predictive factors-namely, presentation, radiographic findings, antibiotic usage, and pleural fluid features-that could predict the need for VATS rather than primary chest tube drainage. METHODS: Forty-nine pediatric patients with pneumonia complicated by parapneumonic effusion or empyema treated at the Children's Hospital of Pittsburgh (1997-2003) were divided into three groups according to the therapy instituted: Primary chest tube, chest tube followed by VATS, or primary VATS. The groups were analyzed in terms of demographics and outcome, as judged by pleural fluid analysis and hospital resource utilization. Demographic and outcome data were compared among groups using one-way analysis of variance and the Student t-test. RESULTS: All groups were similar with respect to demographics and initial antibiotic usage. Patients undergoing primary VATS had a higher initial temperature, whereas radiographic findings of mediastinal shift and air bronchograms were more likely to be found in patients who underwent primary chest tube placement. Patients undergoing primary VATS demonstrated a significantly shorter total stay and lower hospital charges than the other groups. Forty percent of children started on chest tube therapy failed even with subsequent VATS, necessitating a significantly longer hospital course (18 +/- 3 vs. 11 +/- 0.8 days; p < 0.05) and higher hospital charges ($50,000 +/- 7,000 vs. $29,000 +/- 1000) than those having primary VATS. CONCLUSIONS: Patients treated by primary VATS had a shorter stay and lower hospital charges than patients treated by chest tube and antibiotic therapy alone. There were no demographic, physiologic, laboratory, or chest radiographic data that predicted the selection of VATS as an initial treatment. These data suggest a strategy of primary VATS as first-line treatment in the management of empyema or parapneumonic effusion as a complication of pneumonia in pediatric patients.     

Thoracoscopic application of a topical sealant for the management of persistent posttraumatic pneumothorax

BACKGROUND: Persistent posttraumatic pneumothorax (PPP) is an uncommon complication of blunt or penetrating chest trauma. Currently, most patients are managed with pleural chest tube(s) and suction drainage. Prolonged hospital stay and added cost of care are not uncommon. METHODS: Over a 2-year period, 13 patients with PPP, nonresponsive to conventional management, underwent video-assisted thoracoscopic surgery (VATS). As part of our protocol for PPP, routine preoperative computed tomography of the chest and bronchoscopy to determine the presence of associated injuries were performed in all of the patients. During the VATS procedure, all of the patients underwent drainage of any retained hemothorax, and a topical surgical sealant was applied to the source of the air leak as definitive treatment. RESULTS: A persistent pneumothorax with an air leak was identified in all 13 of the patients. There were 10 patients with blunt and 3 patients with penetrating injuries, respectively. The mean age for the patients was 34 years (range, 13 to 64 years). Parenchymal lacerations were identified in all of the patients ranging in size from 0.5 to 3 cm. After the VATS procedure and application of the surgical sealant, 11 patients had the chest tubes removed within 24 hours of the procedure. In the other two patients, the chest tubes were removed within 48 hours. There was no recurrence of the pneumothorax in any of these patients. The mean length of hospital stay before VATS and the application of the surgical sealant was 6 days (range, 2-14 days). CONCLUSION: Early VATS and the use of a topical sealant in patients with PPP is a safe and effective alternative to the conventional management with prolonged thoracostomy chest tubes or an open thoracostomy. This alternative management, when used early in the appropriate patient, will decrease the length of hospital stay, cost of care, and unnecessary procedures.     

Video-assisted thoracoscopy in the early diagnosis and management of post-traumatic pneumothorax and hemothorax

Background Blunt and penetrating chest traumas continue to be associated with a high mortality rate. The related morbidity rate is a also cause for concern because it may result in extended hospitalization and permanent disabilities. The aim of this study was to retrospectively review a series of consecutive patients treated for chest trauma between 1 January 2000 and 31 December 2005, focusing particularly on cases of pneumothorax and hemothorax. alone or in combination, and to critically assess the treatment protocol adopted. Methods Eighty-one patients with pneumothorax and/or hemothorax were subdivided into two groups. Group I (n = 46) comprised 36 patients with an Injury Severity Score (ISS) <9 and 10 patients with ISS from 9 to 15, all of whom were treated with chest tube alone. Group II (n = 35) included 34 patients with an ISS >9 who were treated with tube thoracostomy and VATS and 1 patient was treated by emergency thoracotomy. Results The time to complete recovery was virtually identical in both groups. Conclusions In light of their own experience and of reports in the literature confirming both the diagnostic and therapeutic efficacies of VATS in chest trauma with pneumothorax and/or hemothorax, the authors propose a treatment protocol prescribing its use 48 h from the traumatic event in all cases of uncontrolled air and/or blood loss. This protocol yielded excellent results, including an uneventful postoperative course, rapid resolution of the signs and symptoms of the chest problem, and no disabling sequelae (empyema and fibrothorax), as well as a relatively shorter hospital stay and hence lower costs than with conservative treatment.     

Early Management of Retained Hemothorax in Blunt Head and Chest Trauma

Background

Major blunt chest injury usually leads to the development of retained hemothorax and pneumothorax, and needs further intervention. However, since blunt chest injury may be combined with blunt head injury that typically requires patient observation for 3–4 days, other critical surgical interventions may be delayed. The purpose of this study is to analyze the outcomes of head injury patients who received early, versus delayed thoracic surgeries.

Materials and methods

From May 2005 to February 2012, 61 patients with major blunt injuries to the chest and head were prospectively enrolled. These patients had an intracranial hemorrhage without indications of craniotomy. All the patients received video-assisted thoracoscopic surgery (VATS) due to retained hemothorax or pneumothorax. Patients were divided into two groups according to the time from trauma to operation, this being within 4 days for Group 1 and more than 4 days for Group 2. The clinical outcomes included hospital length of stay (LOS), intensive care unit (ICU) LOS, infection rates, and the time period of ventilator use and chest tube intubation.

Result

All demographics, including age, gender, and trauma severity between the two groups showed no statistical differences. The average time from trauma to operation was 5.8 days. The ventilator usage period, the hospital and ICU length of stay were longer in Group 2 (6.77 vs. 18.55, p = 0.016; 20.63 vs. 35.13, p = 0.003; 8.97 vs. 17.65, p = 0.035). The rates of positive microbial cultures in pleural effusion collected during VATS were higher in Group 2 (6.7 vs. 29.0%, p = 0.043). The Glasgow Coma Scale score for all patients improved when patients were discharged (11.74 vs. 14.10, p < 0.05).

Discussion

In this study, early VATS could be performed safely in brain hemorrhage patients without indication of surgical decompression. The clinical outcomes were much better in patients receiving early intervention within 4 days after trauma.

     

Current indications and results of VATS in the evaluation and management of hemodynamically stable thoracic injuries

Objective: Thoracic injuries are among the most severe forms of trauma and also a leading cause of morbidity and mortality. Video Assisted Thoracic Surgery (VATS) has recently provided an alternative method to simultaneously diagnose and manage patients sustaining chest injuries. We analyze our experience with VATS in the setting of thoracic trauma detailing indications for exploration, procedures performed and results of surgery. Methods: A 6-year single institution review of patients undergoing VATS due to injuries sustained from both blunt and penetrating chest trauma at a Level I trauma center and university teaching hospital. Comparisons were made between groups of blunt and penetrating trauma as to Injury Severity Score (ISS), presence of extra-thoracic injuries, initial thoracostomy drainage and length of postoperative stay. Results: VATS was successfully performed in 19 consecutive patients without conversion to thoracotomy. Indications for exploration included acute hemorrhage, retained hemothorax, suspected diaphragmatic injuries (DI), suspected cardiac injury, intra-thoracic foreign body, persistent airleak and chronic empyema. Procedures performed consisted of evacuation of retained hemothorax, hemostasis of intra-thoracic bleeders, repair of DI, wedge lung resections and decortication. Mean postoperative length of stay was 5.86 days. There were no morbidities. One patient with severe intra-abdominal injuries expired on the first postoperative day. Conclusion: In hemodynamically stable patients with thoracic injuries, VATS provides an accurate assessment of intra-thoracic organ injury and can be utilized to definitively and effectively manage injuries sustained as a result of blunt or penetrating thoracic trauma. VATS should be used with caution in patients sustaining severe and life threatening intra-abdominal injuries.     

Is video-assisted thoracoscopic surgery the best treatment for paediatric pleural empyema?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether video-assisted thoracic surgery (VATS) is the best treatment for paediatric pleural empyema. Altogether 274 papers were found using the reported search, of which 15 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that early VATS (or thoracotomy if VATS not possible) leads to shorter hospitalisation. The duration of chest tube placement and antibiotic use is variable and does not correlate with treatment method. Patients who underwent primary operative therapy had a lower aggregate in-hospital mortality rate (0% vs. 3.3%), re-intervention rate (2.5% vs. 23.5%), length of stay (10.8 days vs. 20.0 days), duration of tube thoracostomy (4.4 days vs. 10.6 days), and duration of antibiotic therapy (12.8 days vs. 21.3 days), compared with patients who underwent non-operative therapy. Similar complication rates were observed for the two groups (5% vs. 5.6%). Moreover, median hospital charges for VATS were $36,320 [interquartile range (IQR), $24,814-$62,269]. The median pharmacy and radiological imaging charges were $5884 (IQR, $3142-$11,357) and $2875 (IQR, $1703-$4950), respectively, for VATS and tube drainage. Adjusting for propensity score matching, costs for primary VATS were equivalent to primary chest tube placement. Only one article found discordant results. Ninety-five children (52%) received antibiotics alone, and 87 (45%) underwent drainage procedures (21 chest tube alone, 57 VATS/thoracotomy, and eight chest tube followed by VATS/thoracotomy); only four received fibrinolytics. Mean (standard deviation) length of stay was significantly shorter in the antibiotics alone group, 7.0 (3.5) days vs. 11 (4.0) days. The strongest predictors of undergoing pleural drainage were admission to the intensive care unit and large effusion size (>1/2 thorax filled).     

Use of a Trauma Service Clinical Pathway to Improve Patient Outcomes for Retained Traumatic Hemothorax

Introduction  Early evacuation of retained hemothorax (RHTX) has been shown to improve clinical outcomes. In 2006, our trauma surgery service instituted a clinical pathway for management of RHTX that was designed to decrease time to operation and improve patient outcomes. We report our experience with early evacuation of posttraumatic RHTX after instituting a service-wide clinical pathway. Methods  From 2006 to 2007, 29 operations were performed by the trauma surgery service for RHTX. Using the clinical pathway, if patients had a persistent effusion on hospital day 2, the patient underwent thoracoscopic (VATS) evacuation of the hemothorax. A case control cohort (24 patients) was generated from 2003 to 2005 of operations for retained hemothorax before implementation of this pathway. Results  The mean age was 33.2 years. There was no difference in ISS between groups (p = 0.14). The study group had significantly decreased time to operating room (3.0 ± 0.33 days vs. 9.9 ± 2.0 days, P = 0.002) and shorter hospital stays (10.8 ± 0.8 days vs. 30.5 ± 5.8 days, P = 0.003). All 29 study patients had their hemothorax evacuated by VATS, whereas 14 of 29 control patients had evacuation attempted by VATS (P = 0.0003). There were no differences in complications or reoperation between groups. Total hospital charges for the study group were $46,471 in the study group compared with $126,221 in the control group (P = 0.03). Conclusions  Implementation of a clinical pathway for early evacuation of retained hemothorax can significantly improve patient outcomes and decrease hospital costs. Furthermore, trauma surgeons are capable of safely performing thoracic surgery for evacuation of retained hemothorax.

How early should VATS be performed for retained haemothorax in blunt chest trauma?

Background

Blunt chest injury is not uncommon in trauma patients. Haemothorax and pneumothorax may occur in these patients, and some of them will develop retained pleural collections. Video-assisted thoracoscopic surgery (VATS) has become an appropriate method for treating these complications, but the optimal timing for performing the surgery and its effects on outcome are not clearly understood.

Materials and methods

In this study, a total of 136 patients who received VATS for the management of retained haemothorax from January 2003 to December 2011 were retrospectively enrolled. All patients had blunt chest injuries and 90% had associated injuries in more than two sites. The time from trauma to operation was recorded and the patients were divided into three groups: 2–3 days (Group 1), 4–6 days (Group 2), and 7 or more days (Group 3). Clinical outcomes such as the length of stay (LOS) at the hospital and intensive care unit (ICU), and duration of ventilator and chest tube use were all recorded and compared between groups.

Results

The mean duration from trauma to operation was 5.9 days. All demographic characteristics showed no statistical differences between groups. Compared with other groups, Group 3 had higher rates of positive microbial cultures in pleural collections and sputum, longer duration of chest tube insertion and ventilator use. Lengths of hospital and ICU stay in Groups 1 and 2 showed no statistical difference, but were longer in Group 3. The frequency of repeated VATS was lower in Group 1 but without statistically significant difference.

Discussion

This study indicated that an early VATS intervention would decrease chest infection. It also reduced the duration of ventilator dependency. The clinical outcomes were significantly better for patients receiving VATS within 3 days under intensive care. In this study, we suggested that VATS might be delayed by associated injuries, but should not exceed 6 days after trauma.     

Diagnostic and treatment strategy for patients with the first episode of primary spontaneous pneumothorax

A retrospective analysis of 198 patients (164 men and 28 women) with the first episode of primary spontaneous pneumothorax (PSP) was made. All the patients underwent diagnostic thoracoscopy (DT) under local anesthesia before insertion of a chest tube. For 115 patients the chest tube thoracoscopy was the only treatment procedure (group I) and 77 patients underwent video-assisted thoracoscopic (VATS) wedge (atypical) resection and pleurectomy (group II). The patients were followed-up from 13 through 77 months. In group I there were 19 recurrences (16.5%), and only two recurrences in group II. In patients of group II having no pathological changes there were no recurrences while in group I there were two (3.3%). The recurrence rate in patients with pathological changes (II, III and IV stages of Vanderschuren classification) was 3% after VATS and as high as 31.5% after the chest tube treatment. The diagnostic thoracoscopy should be performed in all patients with the first episode of PSP for the assessment of the lung and pleura condition. The presence of any pathological changes points to a high risk of recurrences and should be considered as an indication for antirelapse measures (VATS). Surgery is not necessary when no morphological alterations are revealed at DT.     

Frühe Drainagenentfernung nach videoassistierten thorakoskopischen Operationen

BACKGROUND: Chest tubes frequently cause postoperative patient discomfort after video-assisted thoracoscopic surgery (VATS). Therefore, a prospective randomized study was conducted to analyze whether early chest tube removal within 2 h postoperatively is justified in VATS. METHODS: Ninety-three patients fulfilled the inclusion criteria (VATS including wedge resection, complete lung extension on postoperative chest roentgenogram) and showed no exclusion criteria (lung volume reduction surgery, extensive pulmonary fibrosis, pneumothorax, pleural effusion, air fistula). Randomization resulted in early chest tube removal in 48 patients and in conventional chest tube management in 45 patients. RESULTS: Pain intensity was significantly reduced after early chest tube removal (P=0.03, t-test). In consequence, the mean analgesic requirement was significantly reduced (P=0.0001, t-test). The number of postoperative chest roentgenograms was significantly reduced after early chest tube removal (P=0.0001, t-test). The mean postoperative length of hospital stay was 5.4 vs 6.7 days (P=0.11, t-test). No postoperative complication occurred after early chest tube removal, while postoperative complications were observed in six patients with conventional chest tube management (P=0.01, Fisher's test). CONCLUSION: Early chest tube removal after video-assisted thoracoscopic wedge resection is recommended. The inclusion and exclusion criteria of this study should be considered for future early chest tube removal. Long-term follow-up will clarify if early chest tube removal also leads to a reduction in chronic pain.     

Complications in the native lung after single lung transplantation.

OBJECTIVES: Single lung transplantation is a viable option for patients with end-stage pulmonary disease; despite encouraging results, we observed serious complications arising in the native lung. We retrospectively reviewed 36 single lung transplants to evaluate the incidence of complications arising in the native lung, their treatment and outcome. METHODS: Between 1991 and 1997, 35 patients received 36 single lung transplants for emphysema (16), pulmonary fibrosis (14), lymphangioleiomyomatosis (4), primary pulmonary hypertension (1) and bronchiolitis obliterans (1). The clinical records were reviewed and the complications related to the native lung were divided into early (up to 6 weeks after the transplant) and late complications. RESULTS: Nineteen complications occurred in 18 patients (50%), leading to death in nine (25%). Early complications (within 6 weeks from the transplant) were bacterial pneumonia (1), overinflation (3), retention of secretions with bronchial obstruction and atelectasis (1), hemothorax (1), pneumothorax (1) and invasive aspergillosis (3); one patient showed active tuberculosis at the time of transplantation. Two patients developed bacterial pneumonia and invasive aspergillosis leading to sepsis and death. The other complications were treated with separate lung ventilation (1), bronchoscopic clearance (1), chest tube drainage (1) and wedge resection and pleurodesis (mechanical) by VATS (1). One patient with hyperinflation of the native lung eventually required pneumonectomy and died of sepsis. The patient with active tuberculosis is alive and well after 9 months of medical treatment. Late complications were recurrent pneumothorax (4), progressive overinflation with functional deterioration (2), aspergillosis (1) and pulmonary nocardiosis (1). Recurrent pneumothorax was treated with chest tube drainage alone (1), thoracoscopic wedge resection and/or pleurodesis (2) and pneumonectomy (1); hyperinflation was treated with thoracoscopic lung volume reduction in both cases; both patients with late infectious complications died. CONCLUSIONS: After single lung transplantation, the native lung can be the source of serious problems. Early and late infectious complications generally result in a fatal outcome; the other complications can be successfully treated in most cases, even if surgery is required.     

Empyema thoracis

Early recognition of empyema is of prime importance. Accurate assessment of stage is crucial in planning management. Exudative empyema (stage I) should be treated by aspiration or tube thoracostomy. Fibrinopurulent empyema (stage II) can be treated effectively by video-assisted thoracic surgery (VATS). Debridement and decortication are the main components of surgical treatment of stage III empyema. It is worthwhile assessing most cases by video-assisted thoracoscopy.
