Delayed cardiac tamponade and hemothorax induced by an acupuncture needle.

We report a 52-year-old man who presented with cardiac tamponade a few years after accidental breakage of an acupuncture needle that had not been removed. Thoracotomy showed a hemopericardium with penetration of the pulmonary artery by the very fine needle which was barely detected on the chest roentgenogram. This lesion was not suspected on the basis of roentgenography, two-dimensional echocardiography, or computed tomography, but was detected by the presence of other thick needles in the neck, chest and abdomen. This case showed a possible threat of 'stealthy' and migrating foreign bodies, such as very fine acupuncture needles.

Hemopneumothorax missed by auscultation in penetrating chest injury.

OBJECTIVE: To determine the frequency and extent of hemothorax, pneumothorax, and hemopneumothorax missed by auscultation in penetrating chest injury. DESIGN: A retrospective chart and chest radiograph review. MATERIALS AND METHODS: One hundred and eighteen patients suffering penetrating chest injuries during 1993 were studied. A missed auscultation was defined as a patient with normal breath sounds but shown by chest radiograph to have a hemothorax, pneumothorax, or hemopneumothorax. The amount of hemothorax was recorded after chest tube placement or at thoracotomy. The degree of pneumothorax was determined by Rhea's method. RESULTS: Seventy-one patients (60%) had a hemothorax, pneumothorax, or hemopneumothorax. Auscultation to detect hemothorax, pneumothorax, or hemopneumothorax had a sensitivity of 58%, a specificity of 98%, and a positive predictive value of 98%. Thirty of 71 patients (42%) were found to have pleural space blood or air missed by auscultation. Twelve patients (41%) had a hemopneumothorax, 11 patients (36%) had hemothorax, and seven patients (23%) had pneumothorax. Auscultation missed hemothorax up to 600 mL, pneumothorax up to 28%, and hemopneumothorax up to 800 mL and 28%. CONCLUSION: Hemopneumothorax and hemothorax are the conditions most likely to be missed by auscultation, especially in patients with gunshot wounds. Auscultation has a high positive predictive value because it indicates injury with a fair degree of certainty; however, a negative auscultation does not rule out injury.

[The radiological diagnostic and clinical approach to the patient with stab and cut wounds of the chest. The authors' personal experience].

PURPOSE: To report our personal experience with the clinical and radiological diagnostic approach to stab and cut wounds of the thoracic cage and its content, a type of injury whose diagnosis and treatment, as well as the surgical approach, vary case by case. CT of deep penetrating wounds permits correct assessment of severe changes such as pneumothorax, hemothorax and pneumomediastinum. MATERIAL AND METHODS: In the last three years we examined 57 patients (48 men and 9 women; mean age 34 years, range 16-54): chest radiography was performed in 51 of them, with orthogonal projections in the standing and sitting positions. Chest CT was performed in emergency with i.v. contrast agent injection, with scans from the midneck to the diaphragm insertion to study border regions. Thoracostomy with pleural drainage was performed in 35 patients with pneumothorax and hemothorax while thoracotomy was performed in 8 patients, namely 4 with injury to the diaphragm, 2 to the heart, 1 with tear of the main bronchial artery and 1 of the aortic arch. RESULTS: The most frequent symptoms we found were chest pain (100% of cases) and dyspnea (84%); laboratory data showed anemia and decreased hematocrit levels in 28 cases. Chest radiography was negative in 14 cases. The patients were then examined with CT to exclude radiographic underestimation of minimal pneumothorax, small lacerocontusive or hemorrhagic foci and hemothorax, which were observed in 4, 2 and one cases, respectively, and where radiography was actually negative for traumatic changes. Chest radiography was positive in 43 cases: the most frequent finding was pneumothorax, with 37 cases (86%)--8 of them associated with hemothorax and 5 with pneumomediastinum. Lacero-hemorrhagic foci of lung parenchyma were found in 5 cases and single pulmonary hematoma from punch crossing was seen in 1 case. DISCUSSION AND CONCLUSIONS: CT was an accurate tool and had higher sensitivity than chest radiography in detecting and detailing pneumothorax, pneumomediastinum and lacero-hemorrhagic foci, as well as in quantifying hemothorax. Chest radiography had 12% false negatives and therefore we decided to perform CT in all the patients with penetrating wounds to prevent radiographic underestimation. Given the low rate of false negatives (7/57 cases) CT might appear superfluous but since in 2 of these 7 cases we had massive pneumothorax and pneumomediastinum associated with neck emphysema we suggest its use to prevent complications, clinical failures and medicolegal problems. CT permits correct assessment of penetrating stab and cut wounds of the chest and efficient and targeted treatment, which can be conservative, with thoracostomy with pleural drainage, or surgical.

Complications related to subclavian catheters for hemodialysis. Report and review.

Personal experience with subclavian vein cannulations for hemodialysis are given, and the pertinent literature on the subject is reviewed. Two hundred subclavian dialysis catheters were placed in 148 patients who kept them in place for a total of 2,798 days. Immediate complications were two pneumothoraxes and two hemothoraxes due to subclavian artery puncture. Seventeen cases of bacteremia were related to subclavian catheter infections. In 1 case, a complication of sepsis was a vertebral osteomyelitis. Clinical evidences of subclavian vein thrombosis occurred in 5 cases. Life-threatening complications were met in 2 cases: 1 with pericardial tamponade due to right atrium perforation and 1 with mediastinal hematoma and right hemothorax due to superior vena cava perforation. Review of the literature indicates that pneumothoraxes and/or hemothoraxes occurred in 1.7% of the catheter insertions and that sepsis related to subclavian dialysis catheters occurred in 8.9% of the patients. As systematically investigated subclavian vein thrombosis involved at least 50% of the patients. Our 2 personal cases of life-threatening complications and 14 similar cases of the literature were analyzed: left subclavian catheters were associated with superior vena cava perforation with right hemothorax or mediastinal hematoma, while right subclavian catheters gave atrial perforation with pericardial tamponade. Death occurred in 3 of 16 cases, and emergency surgery was required in 5 of 16 cases. Taking into account all these complications, recommendations are made for the use of subclavian dialysis catheters.

Pulmonary artery rupture associated with the Swan-Ganz catheter.

OBJECTIVES: This study was designed to determine the incidence rate, define risk factors, and suggest proper management protocols for pulmonary artery (PA) rupture associated with Swan-Ganz catheters. DESIGN: This is a retrospective chart-review study. SETTING: This study involved 32,442 inpatients requiring hemodynamic monitoring with Swan-Ganz catheters in the operating rooms and ICUs at a large, private teaching hospital over a 17-year period (1975 to 1991). RESULTS: Ten patients sustained PA rupture, yielding an observed rupture rate of 0.031% of catheter insertions. All ten patients had hemoptysis and five (50%) had pulmonary hypertension. Two patients (20%) had undergone anticoagulation at the time of rupture. Four of the six surgical patients were still in surgery at the first sign of rupture. A thoracotomy was performed in five patients. We noted a trend toward survival with thoracotomy, but it was not statistically significant. The overall mortality rate was 70%. When data from our 10 patients were combined with 65 patients from the literature, we found that thoracotomy was essential for survival in patients with hemothorax. There were no survivors among seven patients with hemothorax simply observed, compared with eight (50%) survivors in 16 patients undergoing thoracotomy (p = 0.026). Thirty-nine (75%) of 52 patients without hemothorax survived, whether or not a thoracotomy was performed. CONCLUSIONS: Our study suggested that the incidence of Swan-Ganz catheter-associated PA rupture is 0.031% and that an urgent thoracotomy should be performed if hemothorax is present at any point.

[Video-thoracoscopy in the treatment of patients with penetrating wound of the thorax].

Thoracoscopic surgical procedures were used in the treatment of 79 patients with penetrating wound of the thorax complicated by hemothorax. Small hemothorax was diagnosed in 72.1% patients; 56.1% had injuries of thoracic organs, 26.3% -- injuries of diaphragm. Thoracoscopic hemostasis and correction of intrathoracic injuries were performed in 84,6% patients. Conversion to video-assisted minimally-invasive thoracotomy (because of injuries of the diaphragm as a rule) occurred in 15,8% patients, conversion to typical thoracotomy -- in 3.5%. In medium hemothorax (16.4% patients) injuries of thoracic organs and anatomic structures were diagnosed in 76.9% cases. Hemostasis and correction of intrathoracic injuries through thoracoscopic approach were performed in 43.8% patients, conversion to typical thoracotomy was necessary in 7% cases. Big hemothorax was diagnosed in 11.4% patients, 55.6% of them had injuries of thoracic organs and anatomic structures. Complete thoracoscopic procedure was performed in 44.4% cases; 33.3 patients required conversion to thoracotomy. Thoracoscopy is an effective method of surgical treatment of thoracic injuries in patients who don't require urgent thoracotomy. This procedure permits repair of intrathoracic injuries in 73.4% cases. Postoperative complications were seen in 15% cases, postoperative lethality was 1.4%.

Factors predicting early in-hospital death in blunt thoracic aortic injury.

BACKGROUND: Despite technical advances in the diagnosis and repair of blunt thoracic aortic injury (TAI),1,2 patients continue to die after arrival at trauma centers. Most of these deaths occur consequent to free intrapleural aortic rupture before surgical repair. We sought to identify characteristics of the subpopulation of blunt TAI patients at particular risk for early in-hospital death. METHODS: The records of a Level I trauma center were reviewed for the period from 1/1/90 through 5/1/00. Fifty-one patients with aortic injury were identified. A subgroup was identified with isolated aortic injury. The resultant study group consisted of 26 patients and included 11 cases of free rupture (FR) and 15 cases of contained rupture (CR). Data from both groups were analyzed for mechanism, abnormal vital signs, initial chest radiographic findings, symptoms, physical findings, time course from injury to rupture or treatment, clinical outcome, and pathologic findings. RESULTS: All 11 of the FR group died. In the CR group, 14/15 survived. Mechanism in all cases was "high-speed" or "head-on" motor vehicle collision. All cases with FR had the mediastinal abnormalities of "grossly widened mediastinum" + hemothorax; 10/11 had an episode of transient hypotension that initially responded to fluid resuscitation before their terminal event. In the CR group, there were a variety of chest radiographic findings, but only one "grossly widened mediastinum," no hemothorax, and no incidences of hypotension. However, multivariate analysis revealed that the combination of grossly widened mediastinum + hemothorax + transient hypotension was strongly and uniquely associated with those patients who went on to have free rupture (FR group) (p < 0.00001, Fisher's exact test). CONCLUSION: For patients exposed to a high-speed decelerative mechanism, the constellation of "grossly widened mediastinum + hemothorax with transient hemodynamic instability" appears not only to be highly specific for aortic injury but also to be a marker of impending sudden death from free rupture. This association would seem to warrant immediate surgery in this high-risk group without the traditional diagnostic studies.

Operative videothoracoscopy in the surgical treatment of penetrating firearms wounds of the chest.

We prospectively analyzed our experience with operative videothoracoscopy (OVT) performed in a field military hospital in cases of penetrating firearms wounds of the thorax (PFAWT) sustained in Chechnya. From February to April 1996, we treated 206 wounded patients, of whom 37 (18.0%) had sustained chest injuries. PFAWT were present in 23 soldiers, accounting for 62.2% of all chest injuries. Twelve injuries were confined to the thorax, eight patients had associated injuries, and three soldiers had thoracoabdominal injuries. Nineteen patients had pleural drainage performed during medical evacuation. The thoracic injuries were right-sided (17), involved bullets or shell splinters (23); were through and through (16), represented solitary wounds (19), and were associated with internal organ injuries (21). Fifteen patients had indications for OVT when they were delivered from the battle-field 1.5 to 22 hours after injury. All patients manifested signs of hemorrhagic shock and hemodynamic instability. Indications for OVT were ongoing intrapleural bleeding (6), clotted hemothorax (6), or marked air leakage (3) preventing lung inflation with the OP-02 apparatus (field modification). OVT revealed 12 lung wounds, nine of which were multiple wounds, pleural bleeding in 6 patients, clotted hemothorax in 11 patients, and foreign bodies in 5 patients. Two patients underwent thoracotomy, one for suspicion of heart injury and the second because we could not adequately visualize and control bleeding revealed at OVT to be from the intercostal artery in the left costovertebral angle. Eight of 23 patients had no indication for operative videothoracoscopy and were managed with continued pleural aspiration and drug therapy. Wedge resection of the lung using an Endo-GIA-30 stapler was necessary in two patients because of parenchymal destruction and bleeding. Evacuation of clotted blood by fragmentation and aspiration was satisfactory in all cases. Satisfactory manual suturing of selected lung injuries was obtained largely with intracorporeal knot tying. The duration of the procedures ranged from 40 to 90 minutes. No morbidity nor mortality was encountered in patients undergoing OVT. Postoperative pain was minimized by using OVT placement of catheters in the chest wall soft tissue with local administration of 2% Trimecain. Patients were able to stand in 10 to 12 hours and to walk by the end of the first postoperative day. All patients who underwent OVT were evacuated without drains by the third or fourth postoperative day, all tolerating sitting and standing positions. We conclude that early OVT in the military field hospital for continued bleeding, clotted hemothorax, and continued major air leakage has several advantages in military patients with PFAWT: early definition and management of organ injury; identification and control of bleeding in most instances; earlier and more accurate assessment for thoracotomy; vigorous lavage and removal of projectiles such as bone fragments and evacuation of clotted hemothorax; early debridement with suture closure of the thoracic wall canal; and minimal postoperative pain with dramatically reduced suppurative sequelae and bronchopleural fistulae.

[Shock room diagnosis in polytrauma. Value of thoracic CT].

OBJECTIVE: The aim of this prospective study was to evaluate whether early thoracic computed tomography (TCT) is superior to routine chest X-ray (CXR) in the diagnostic work-up of blunt thoracic trauma and whether the additional information obtained influences subsequent decisions on therapy in the early management of severely injured patients. PATIENTS AND METHODS: In a prospective study of 103 consecutive patients with clinical or radiological signs of chest trauma (94 multiply injured patients with chest trauma, 9 patients with isolated chest trauma) who had an average ISS of 30 and an average AIS thorax of 3, initial CXR and TCT were compared after the first assessment in our emergency department (a level I trauma center). Mortality in this group was 10% (n = 10). RESULTS: In 67 patients (65%) TCT revealed major complications of chest trauma that had been missed on CXR: lung contusion (n = 33), pneumothorax (n = 27), residual pneumothorax after chest tube placement (n = 7), hemothorax ((n = 21), displaced chest tube (n = 5), diaphragmatic rupture (n = 2), myocardial rupture (n = 1); in 11 patients only minor additional pathologic findings (dystelectasis, small pleural effusion) were visualized on TCT; and in 14 patients CXR and TCT showed identical pathologic results. In 11 patients neither CXR nor TCT revealed pathologic findings. The TCT scan was significantly more effective than routine CXR in detecting lung contusions (P < 0.001), pneumothorax (P < 0.005) and hemothorax (P < 0.05). In 42 patients (41%) the additional TCT findings did affect, the therapy selected: chest tube placement or chest tube correction in mostly anteriorly located pneumothoraces or large hemothoraces (n = 31), influence on ventilation mode and respiratory care (n = 14), influence on the management of fracture stabilization (n = 12), laparotomy in cases of diaphragmatic lacerations (n = 2), bronchoscopy for atelectasis (n = 2), exclusion of aortic rupture (n = 2), endotracheal intubation (n = 1), pericardiocentesis (n = 1). CONCLUSIONS: TCT is highly sensitive in detecting thoracic injuries after blunt chest trauma and is superior to routine CXR in visualizing lung contusions and pneumo- and hemothorax. Early TCT influences therapeutic management in a considerable subset of patients. We therefore recommend TCT in the primary diagnostic work-up of multiple injured patients with suspected chest trauma, because early and accurate diagnosis of all thoracic injuries along with acceptance of the implications for therapy may reduce complications and improve the outcome in polytraumatized patients with blunt chest trauma.

Thoracic endometriosis syndrome: new observations from an analysis of 110 cases.

PURPOSE: To determine the demographics, clinical presentations, pathological findings, and the effectiveness of treatment in 110 patients with thoracic endometriosis syndrome (TES). METHODS: Retrospective analysis based on data published in the English medical literature. RESULTS: The mean age at presentation of TES was 35 +/- 0.6 years (+/- standard error of the mean) with a range from 15 to 54. The trends of age-specific incidence for pelvic endometriosis and TES were similar. The peak incidence for pelvic endometriosis occurred between 24 and 29 years, whereas the peak incidence for TES was between 30 and 34 years. Pneumothorax was the most common presentation, occurring in 80 of 110 (73%), followed by hemothorax in 15 (14%), hemoptysis in 8 (7%), and lung nodules in 7 (6%). The right hemithorax was involved in more than 90% of all manifestations except for nodules. Hemothorax was more often associated with presence of pleural and pelvic endometriosis compared with other manifestations (P < 0.003, P < 0.02). Compared with hormonal treatment, surgical pleurodesis resulted in low recurrence rate for pneumothorax or hemothorax among patients treated with danazol or oral contraceptives. CONCLUSIONS: There is a significant association between the presence of pelvic endometriosis and TES, with the latter occurring approximately 5 years later. Pneumothorax is the most common manifestation. The most plausible explanation for pathogenesis involves peritoneal-pleural movement of endometrial tissue through diaphragmatic defects and microembolization through pelvic veins. Diagnosis is established on clinical grounds in most cases. Surgical pleural abrasion is superior to hormonal treatment in the long-term management of pneumothorax. Earlier diagnosis and effective therapy of TES can decrease the morbidity of this disease in women during their reproductive period.

Preliminary report on videothoracoscopy in the evaluation and treatment of thoracic injury.

A prospective trial of videothoracoscopy was conducted at an urban trauma center between February 1992 and February 1993 to determine the efficiency of this less invasive method of evaluation and treatment. Twenty-four consecutive patients with chest trauma (penetrating, n = 22; blunt, n = 2) were examined thoracoscopically for clotted hemothorax that otherwise would have been treated with thoracotomy (n = 9), suspected diaphragmatic injury (n = 10), and continued bleeding (n = 5). To ensure maximal exposure, general anesthesia with a double-lumen endotracheal tube was used in each patient. Clotted hemothorax was successfully evacuated in eight of nine patients (89%). Diaphragmatic laceration was suspected in 10 patients (2 abnormal chest radiographs, 8 proximity penetrating wounds) and confirmed thoracoscopically in 5. In four patients, diaphragmatic lacerations were successfully repaired with thoracoscopic techniques. Five patients underwent thoracoscopy for continued hemorrhage (greater than 1,500 mL per 24 hours) after tube thoracostomy. Intercostal artery injury was confirmed in all patients, and diathermy provided hemostasis in three patients without thoracotomy. No complications occurred. These data suggest the following: (1) Videothoracoscopy is an accurate, safe, and minimally invasive method for the assessment of diaphragmatic injuries, control of continued chest wall bleeding, and early evacuation of clotted hemothorax. (2) This technique should be used more frequently in patients with thoracic trauma. (3) Technical advances may expand the therapeutic role of thoracoscopy.

The role of videothoracoscopy in management of precordial thoracic penetrating injuries.

OBJECTIVES: To report on the value of diagnostic videothoracoscopy in patients with possible penetrating cardiac wounds. METHODS: Thirteen patients admitted over a 4 year period with hemodynamic stability and a penetrating injury in cardiac proximity had exploratory videothoracoscopy. All data related to those patients were retrospectively reviewed. RESULTS: Eighty-five percent of patients had videothoracoscopy within 8 h of trauma. In most cases (eight of 13), operations were performed on patients in the supine position with the chest slightly rotated. Nine patients had a left hemothorax, five had pulmonary lacerations and five had a bleeding parietal vessel. Pericardial exploration was achieved either by direct vision (nine patients), or by the performance of a pericardial window (four patients). Acute hemopericardium related to a cardiac wound was diagnosed in two patients. Procedures included evacuation of clotted hemothorax (six patients), stapling of pulmonary laceration (four patients), and electrocoagulation of bleeding parietal vessel (four patients). Four patients required conversion to thoracotomy: two for repair of a cardiac wound, one for adequate exposure of the pericardium and one for ligation of a bleeding intercostal artery. The mean operative time was 37+/-23 min. Two patients experienced postoperative complications (coagulopathy, subcutaneous emphysema) and the in-hospital mortality was 0%. The mean hospital stay was 10+/-4 days. CONCLUSIONS: In the hands of an experienced surgeon, videothoracoscopy may represent a valid alternative to subxiphoid pericardial window in patients with hemodynamic stability and a suspected cardiac wound. Videothoracoscopy can rule out a cardiac injury and allows for the performance of associated procedures such as diaphragm assessment/repair, evacuation of clotted hemothorax, hemostasis of parietal vessels or pulmonary laceration and removal of projectiles.
